Humanity’s Farthest Signal: Voyager 1 Hits One Light-Day

NASA has confirmed that Voyager 1 will reach a distance of one light-day from Earth on November 18, 2026, making it the first human-made spacecraft to achieve this milestone. At that point, signals will take a full 24 hours to travel between Earth and the probe.

Voyager 1 was launched by NASA on September 5, 1977, at 12:56 UTC from Cape Canaveral, Florida, aboard a Titan IIIE rocket. It was part of the Voyager program, designed to explore the outer planets and eventually interstellar space.

Voyager 1 is the most distant human-made object, traveling toward the constellation Ophiuchus. It carries a phonograph record with sounds, images, and music representing Earth’s diversity.

Voyager 1 entered interstellar space on August 25, 2012.

The Milestone

• Exact Date & Time: November 18, 2026, at 2:16:07 AM PST (10:16:07 AM UTC / 12:16:07 AM CST)
• Distance: ~16.1 billion miles (25.9 billion km), equal to 173.14 astronomical units (AU)
• Speed: Voyager 1 is traveling at ~79,960 mph (128,700 km/h)
• Signal Delay: Commands from Earth will take 24 hours to reach Voyager 1, and another 24 hours for data to return

Voyager 1’s Journey

• Launch: September 5, 1977, from Cape Canaveral
• Planetary Encounters: Discovered active volcanoes on Jupiter’s moon Io; revealed Saturn’s rings; studied Titan’s atmosphere
• Interstellar Crossing: Entered interstellar space on August 25, 2012, after crossing the heliopause
• Trajectory: Voyager 1 is headed toward the constellation Ophiuchus, moving “up” out of the solar plane

Voyager Program Legacy

• Voyager 2: Launched earlier in 1977, visited all four gas giants (Jupiter, Saturn, Uranus, Neptune). It is ~2 billion miles closer to Earth and moving slower, so it will never catch up
• Golden Record: Both spacecraft carry a phonograph record with sounds, music, and images representing Earth’s diversity — a symbolic message to extraterrestrial civilizations
• Longevity Efforts: NASA engineers are shutting down non-essential instruments to conserve power. In 2025, the Cosmic Ray Subsystem was turned off. Future interventions are planned to extend the mission

Why It Matters

• Scientific Value: Voyager 1 continues to send back data about the interstellar medium, helping scientists understand the boundary between our solar system and deep space
• Cultural Impact: This milestone highlights humanity’s ability to send technology beyond its cradle, inspiring future missions like interstellar probes and deep space exploration

• Discovery Tool: Hubble Space Telescope
• Distance: ~300 million light-years from the Earth
• Composition: At least 99.9% dark matter, with vanishingly few visible stars
• Detection Method: Identified through the presence of four globular clusters orbiting an otherwise invisible mass
• Visibility: Nearly invisible in optical wavelengths

Why This Matters

• Dark Galaxies: CDG-2 is a strong candidate for the long-hypothesized class of “dark galaxies.”
• Cosmological Significance: Dark matter outweighs normal matter in the universe by about 5-to-1.
• Scientific Opportunity: Studying CDG-2 could help astronomers understand galaxy formation when star birth is suppressed.

Comparison: Typical Galaxy vs. CDG-2

Feature	Typical Spiral Galaxy (e.g., Milky Way)	CDG-2 (Candidate Dark Galaxy)
Dark Matter Fraction	~85–90%	~99.9%
Visible Stars	Hundreds of billions	Almost none (detected via clusters)
Detection Method	Direct observation of stars & gas	Indirect, via globular clusters
Brightness	High, easily visible	Extremely faint, nearly invisible

Challenges & Open Questions

• Verification: Further observations needed, possibly using radio telescopes or gravitational lensing.
• Formation Myst ery: Why did CDG-2 fail to form stars?
• Implications: More galaxies like CDG-2 could reshape our understanding of cosmic structure.

Takeaway

CDG-2 is one of the most compelling candidates yet for a “dark galaxy,” offering a rare glimpse into a realm where dark matter reigns almost completely unchecked. Its discovery underscores how much of the universe remains hidden and how vital tools like Hubble are in uncovering these cosmic mysteries.

NASA Discovers Heart-Shaped Wonders on Mars

In a delightful twist to planetary science, NASA's Mars Reconnaissance Orbiter has captured images of dozens of heart-shaped landforms sprinkled across the Martian surface—turning the cold, red expanse into a gallery of cosmic affection.

These curious shapes have appeared in various regions, from Arabia Terra to the southern highlands. While they might evoke sentiments of love and whimsy, scientists assure us they’re no extraterrestrial Valentine’s messages. Instead, they’re crafted by natural forces over millions of years.

How Does Mars Carve Out a Heart?

• Impact Craters: Small meteoroids collide with Mars, revealing lighter sediment underneath and sculpting crater patterns that coincidentally resemble hearts.
• Erosion & Volcanism: Mesas and depressions, shaped by erosion or volcanic activity, also contribute to heart-like silhouettes.
• Lighting & Shadows: Martian sunlight plays visual tricks—enhancing ridges and dips to accentuate these romantic outlines.

“It's one of those moments where science meets poetry,” remarked Dr. Alisha Grant, a planetary geologist at NASA's Jet Propulsion Laboratory. “We're interpreting nature’s randomness as a symbol of something very human.”

Mars: The Solar System’s Secret Romantic?

NASA has been sharing these striking visuals each year around Valentine’s Day, fueling public fascination. One post even quipped, “Looks like Mars has been secretly playing Cupid all along.”

The trend has gained momentum online, with space enthusiasts tagging their favorite heart-shaped formations and debating whether the Red Planet deserves a new nickname: ‘The Loveliest Planet.’

What It Means for Science & Storytelling

While the formations are scientifically valuable—helping researchers analyze erosion patterns, geological layering, and ancient water flows—they also serve a purpose beyond data. They invite the public to engage with space exploration in a playful, emotional way.

After all, when a distant planet 225 million kilometers away starts resembling symbols of love, it’s hard not to feel a cosmic connection.

Ghost Waves Beneath the Ice: NASA's ANITA Hears What Shouldn't Exist

High above Antarctica, a NASA experiment called ANITA (Antarctic Impulsive Transient Antenna) detected radio waves coming from beneath the ice — at angles around 30° below the surface. That’s a big deal because, according to the Standard Model of particle physics, such signals should be absorbed by thousands of kilometers of rock before ever reaching the surface. Yet, somehow, they made it through.

Initially, scientists thought these might be caused by neutrinos, those ghostly subatomic particles that rarely interact with matter. But the angles and behavior of the signals don’t match what we’d expect from neutrinos. Researchers have ruled out known particle interactions, background noise, and even checked data from other observatories like Pierre Auger in Argentina — still no satisfying.

The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere.

Some theorists are now floating ideas that range from dark matter interactions to new physics beyond the Standard Model. Others suggest we might be seeing an unknown behavior of radio waves near ice or the horizon. A new balloon-based detector called PUEO is expected to launch soon to gather more data and hopefully crack the case.

ANITA was placed in Antarctica because there is little chance of interference from other signals. To capture the emission signals, the balloon-borne radio detector is sent to fly over stretches of ice, capturing what are called ice showers. Credit: Stephanie Wissel / Penn State.

After ANITA's balloon-borne detectors picked up those impossible upward-traveling radio pulses (in both 2006 and 2014), researchers ruled out neutrinos as the cause. The angles were just too steep — around 30° below the horizon — meaning any particle would’ve had to pass through nearly 3,000 km of solid Earth. That’s a feat no known particle can pull off.

To double-check, scientists turned to other observatories like IceCube in Antarctica and Pierre Auger in Argentina. Neither found matching events, reinforcing the anomaly. Theories now range from exotic particles to unknown radio propagation effects near ice or the horizon — but none fully explain the signals.

Enter PUEO — the Payload for Ultrahigh Energy Observations. It’s ANITA’s successor, slated to launch soon with five times the sensitivity. It’ll carry more antennas and upgraded electronics to hunt for similar signals and hopefully determine whether we’re seeing new physics or just misunderstood phenomena.

Stephanie Wissel, a lead physicist on the project, summed it up best:

It's one of those long-standing mysteries. We’ve ruled out what it’s not — now we’re trying to figure out what it is

It’s like the ice is whispering secrets from a realm we haven’t yet mapped. Want to dive deeper into the theories — dark matter, exotic particles, or even the more speculative ones? Follow IndianWeb2.com on X, LinkedIn or Facebook.

NASA Fast-Tracks Mars Missions, Puts Lunar Plans on Hold

NASA is considering launching missions to Mars as early as next year, marking a significant shift in priorities. This change comes after the U.S. administration released its proposed budget, which emphasizes landing a human on Mars and allocates an additional $1 billion for Mars-related projects.

SpaceX's Starship is expected to play a key role in these missions, given its capability to reach the Red Planet. The agency is evaluating launch windows in 2026 and 2028 to test technologies that will support human exploration on Mars. However, this shift may lead to tensions with lawmakers who have mandated NASA to focus on a long-term lunar presence.

With this NASA's shift toward Mars missions is causing major changes to its lunar exploration plans. The Artemis program, which was designed to establish a long-term human presence on the Moon, is facing significant cuts. The Space Launch System (SLS) rocket and Orion crew capsule—key components of Artemis—are set to be retired after Artemis 3, the first planned crewed Moon landing. Additionally, the lunar Gateway space station, which was meant to serve as a staging point for deep-space missions, is being canceled.

Despite these cuts, NASA is still allocating over $7 billion for lunar exploration. However, the agency is shifting toward commercial alternatives, such as SpaceX's Starship, to support future Moon missions. This move aligns with the administration’s goal of prioritizing Mars while maintaining a presence on the Moon.

Notably, NASA and ISRO's NISAR mission remains on track despite NASA's shift toward Mars. The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is scheduled for launch in June 2025. This Earth observation mission will use dual-frequency radar (L-band and S-band) to monitor changes in landforms, ice sheets, and ecosystems every 12 days.

While NASA is prioritizing Mars, NISAR's funding and development remain intact, as it serves a different purpose—tracking environmental changes, disaster management, and infrastructure monitoring. The satellite is currently undergoing final integration at ISRO's Satish Dhawan Space Centre in Sriharikota.

So, while NASA's deep-space ambitions are shifting, its collaboration with ISRO on Earth science remains strong.

This shift of priorities from NASA is sparking concerns among lawmakers and international partners, as NASA had previously committed to a sustained lunar presence. What do you think, should NASA focus on Mars, or is the Moon still a crucial stepping stone? Do comment your opinion below...

50 Yrs of Climate Change: NASA Image Shows The 'Blue Planet' Has Turned Grey

Half a century ago, Earth was a shimmering marble in the void—a planet so vibrantly blue, its image from space became a symbol of purity, balance, and life. But in the last 50 years, that celestial blue has dimmed, clouded by the scars of human progress. Rising temperatures, poisoned oceans, and vanishing forests—our home has morphed into something unrecognizable.

The Apollo 8 images from 1968 captured Earth in its pristine glory, a vibrant blue sphere untouched by the extreme climate shifts we see today. Meanwhile, NASA's EPIC (Earth Polychromatic Imaging Camera) images from 2025 provide a stark contrast, revealing the effects of rising temperatures, pollution, and deforestation.

1968: A pristine, thriving Blue Planet. The beginning of space exploration and hope.

Explore these images here:

• 1968 Apollo 8 Earth View: [See it here]
• 2025 NASA EPIC Earth View: [See it here]

Besides this 1968 photo, the original slide film of the famous 1972 Blue Marble photograph was taken by the Apollo 17 crew on December 7, 1972, during their journey to the Moon. This iconic image, officially designated AS17-148-22727, became one of the most widely distributed photographs in history, showcasing Earth in its full, illuminated glory.

This classic photograph of the Earth was taken on December 7, 1972.

• NASA's archival records: [View here].
• Agent Gallery Chicago, which offers a large transparency slide of the image: [See details]

This image was groundbreaking because it was the first time astronauts could capture the entire Earth, including the South Pole, in a single frame. It remains a powerful reminder of our planet’s beauty and fragility.

The Warning We Ignored

The first murmurs of a climate crisis emerged in the 1970s, when scientists started linking fossil fuel emissions to global temperature rise. Fast forward to today, and their predictions have become stark reality. Glaciers retreat like beaten warriors, islands sink beneath rising tides, and entire species are disappearing before our eyes. The warnings were there, yet humanity plowed ahead, chasing industrial expansion and unchecked consumption.

Oceans: The Fading Blue

2025: A fading, wounded Earth. 50 years of climate change and the fight for survival. (NASA Image taken on 22 April 2025) 

Once a vast cradle of life, our oceans bear the deepest wounds. Nearly 30% more acidic than 50 years ago, their coral reefs bleach into graveyards, unable to withstand relentless temperature spikes. Polluted waters choke marine ecosystems, while plastic islands float aimlessly—monuments to our disregard for nature. What was once Earth's lifeblood has transformed into a struggling, poisoned entity.

Forests: The Vanishing Green

The lungs of our planet are collapsing. The Amazon, once infinite in its stretch, has lost millions of acres. Climate-triggered wildfires ravage Australia and California with apocalyptic force, leaving behind a scorched wasteland. Trees—nature’s most efficient carbon scrubbers—are being erased at an alarming rate, allowing carbon dioxide to fill the air like an invisible plague.

A dramatic comparison between 2000 and 2015 reveals vast areas of forest replaced by roads and plantations.

The Temperature Siege

We've surpassed tipping points once thought unimaginable. The last decade was the hottest in recorded history, with summers stretching longer and fiercer, and winters becoming erratic. As Arctic ice melts, new pathways open for geopolitical ambition, but at a devastating cost—the loss of an ancient ecosystem. Cities once considered safe from climate threats are now battling floods, heatwaves, and resource scarcity.

What Now?

Despite the bleak picture, all is not lost. Renewable energy innovations, ambitious climate agreements, and the relentless fight of environmental activists offer glimpses of hope. Nations are slowly shifting towards greener economies, corporations are being held accountable, and individuals are embracing sustainable habits. The Earth’s wounds are deep, but not irreparable—if we act, if we adapt, if we revolutionize.

The question remains: Will we restore the blue that made Earth the envy of the cosmos, or will we stand idly as it fades to gray?

Sunita Williams to Return Safely on March 19: Sr Scientist at NASA-JPL

• “Sunita Williams to return home safely on March 19”: Dr. Goutam Chattopadhyay at ABP Network’s Ideas of India 2025
• “There is no conspiracy theory here; Sunita Williams’ return was delayed due to a technical glitch,” said Dr. Goutam Chattopadhyay
• “We have not found life outside Earth; not even a single cell,” said Dr. Goutam Chattopadhyay

“There is no conspiracy theory here. NASA is not keeping Sunita Williams in space. Sunita Williams’ return was delayed due to a technical glitch, but on March 19, they will be safely back home. In fact, we are using this opportunity to explore space further,” Dr. Goutam Chattopadhyay, Senior Scientist at NASA's Jet Propulsion Laboratory and Visiting Professor at Caltech said on NASA’s Sunita Williams stuck on the International Space Station (ISS) at ABP Network’s Ideas of India 2025 in Mumbai, today.

Against the backdrop of India's growing leadership in space exploration, Dr. Goutam Chattopadhyay, exploring humanity's latest discoveries in the quest to understand the universe, said, “Can life exist outside of Earth? The answer is yes. But we have not found life outside of Earth; not even a single cell. But with 400 billion stars and the majority having planets revolving around them, the probability of life existing beyond Earth is there. Our goal is to find a planet where life is sustainable.”

Speaking at the session ‘Adventures in Space – Our Place in the Universe,’ Dr. Goutam Chattopadhyay, added, “We search for the unknown with the knowledge of the known. But we don’t even know what kind of life could start or where it may exist. That is what we are trying to figure out. The best place to live a happy life in this universe is our Earth. Why should we go live on Mars? We can send you there if you want, but it’s a one-way ticket.”

Dr. Goutam Chattopadhyay also spoke on India’s unmatched potential in the global landscape, stating, “ISRO and NASA are collaborating on a project right now. ISRO is doing great and executing successful missions.”

Talking about how astronomy is different from astrology, Dr. Goutam Chattopadhyay said, “Astronomy truly opens up your vision to the universe and it is a big mystery that we are trying to solve."

ABP Network’s Ideas of India 2025, centred on the theme ‘Humanity’s Next Frontier’, will bring together thought leaders and innovators to explore the challenges and opportunities in India’s ascendance in a rapidly changing world. In the face of climate change, geopolitical conflicts, and technological advancements such as AI, the summit delved into India’s role as both an ancient civilisation and a demographic powerhouse in shaping the future.

China Dam Slowing Down Earth's Rotation, Says NASA

The Three Gorges Dam in China had a measurable impact on Earth's rotation, says scientists from the US space agency NASA. The dam spans the Yangtze River in Hubei province, China. It is about 2,335 meters (7,660 feet) long and 185 meters (607 feet) high. The reservoir created by the dam is 600 kilometers (370 miles) long and can hold up to 39.3 cubic kilometers (9.43 cubic miles) of water.

The primary purpose of the dam is to generate electricity. It has an installed capacity of 22,500 megawatts, making it the largest hydroelectric power station in the world.

The massive weight of the water stored in the dam's reservoir has increased Earth's moment of inertia. This means that the distribution of Earth's mass has changed, causing a slight decrease in the speed of Earth's rotation.

As a result, the length of a day has increased by about 0.06 microseconds. While this change is incredibly small and not noticeable in daily life, it is scientifically significant.

 If filled, the dam would hold 40 cubic kilometers (10 trillion gallons) of water. That shift of mass would increase the length of day by only 0.06 microseconds and make the Earth only very slightly more round in the middle and flat on the top. It would shift the pole position by about two centimeters (0.8 inch).

Other Effects

Power Generation: The dam generates a massive amount of electricity, approximately 88.2 billion kWh annually, making it the world's largest hydroelectric power station.

Environmental Impact: The construction and operation of the dam have led to significant environmental changes, including the relocation of over 1.2 million people and the flooding of large.

Future Projects

China is planning to build an even larger dam on the Yarlung Tsangpo River, which could have even more pronounced effects on Earth's rotation and the environment.

How Do Astronauts Vote From Space?

Fascinating blend of technology and democracy are working together to ensure everyone's voice can be heard, even from outer space.

Astronauts have the unique opportunity to vote from space, thanks to a special process set up by NASA.

The First Vote from Outer Space

David Wolf, the first American to vote in space, relaxes in the Spacehab module while Space Shuttle Atlantis was docked to Mir (10/16/1997)

The very first vote from space was cast by NASA astronaut David Wolf in 1997 while he was aboard Russia's Mir Space Station. This historic event was made possible by legislation passed by the Texas Legislature, which allowed NASA astronauts to cast ballots from orbit. The process involved sending an encrypted electronic ballot to the astronaut, which was then transmitted back to Earth and delivered to the appropriate county clerk's office.

Why Astronauts have to Vote from the Space?

The ability for astronauts to vote from space ensures that they can participate in the democratic process, even while they are on extended missions. It's a testament to the importance of civic duty and the innovative ways technology can support it.

Astronauts vote from space primarily because they may be on extended missions during election periods and cannot return to Earth to cast their ballots. This process ensures that astronauts can still participate in the democratic process while fulfilling their duties aboard the International Space Station (ISS) or other space missions.

1. Application for Absentee Ballot: Before their mission, astronauts fill out a Federal Post Card Application (FPCA) to request an absentee ballot.

2. Secure Transmission: NASA's Johnson Space Center in Houston sends the encrypted electronic ballot to the astronaut via a secure communication system.

3. Voting from Space: The astronaut fills out the ballot on an onboard computer, which is equipped with unique credentials to ensure security.

4. Transmission Back to Earth: The completed ballot is then encrypted and transmitted back to Earth using NASA's Tracking and Data Relay Satellite System (TDRSS).

5. Final Delivery: The ballot is relayed to the county clerk's office responsible for casting the ballot.

This process ensures that astronauts can participate in the democratic process even while they are orbiting Earth

Indian Conglomerate Scouts for NASA's Next Space Station

An Indian multinational conglomerate, which has been a key partner for the Indian space agency ISRO for over five decades, is exploring opportunities to contribute to NASA's successor to the International Space Station (ISS).

Mumbai, Maharashtra-headquartered Larsen & Toubro (L&T) has been a key player in powering ISRO's space missions for over five decades and is now looking to expand its reach to the international market. L&T is hopeful that Indian firms will play a role in the supply chain for America's next space station.

Vikas Khita, Vice President of L&T Precision Engineering and Systems, mentioned that while earlier talks with Blue Origin for supplying orbital launch capabilities and space habitat solutions faced challenges, remnants of those discussions are still ongoing, now involving NASA.

Khita told news agency PTI that L&T has been in discussions with Blue Origin, a Jeff Bezos's aerospace manufacturer, for supplying orbital launch capabilities and space habitat solutions.

While these talks encountered some challenges, remnants of the discussions are still ongoing, now involving NASA.

NASA is collaborating on developing a space station owned, built, and operated by a private company — either Axiom Space, Voyager Space, or Blue Origin. NASA is giving each company hundreds of millions of dollars in funding and sharing their expertise with them.

NASA's next space station is called Gateway. It's a lunar space station designed to support deep space exploration and serve as a multi-purpose outpost for lunar surface missions, science in lunar orbit, and human exploration further into the cosmos. Gateway is central to NASA's Artemis missions, which aim to return humans to the Moon and eventually pave the way for human missions to Mars and beyond.

Known as India's largest engineering firm, Larsen & Toubro (L&T) has been involved in the fabrication of various satellites for ISRO, including the GSAT series and IRNSS (Indian Regional Navigation Satellite System) satellites.

Moreover, L&T has even contributed to the development of ISRO's launch vehicles, including the Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). L&T is also involved in ISRO's Gaganyaan program, which aims to send Indian astronauts into space.

L&T is also interested in building space ports, space parks, and manufacturing clusters, aligning with the Indian government's decision to open up the space sector for private participation.

Next-Gen Spacesuits to Allow Astronauts Communicate via Voice and Video

Soon, Astronauts will be able to communicate more effectively with mission control and other crew members on the lunar surface. This real-time communication can improve safety, coordination, and decision-making during missions.

Artemis III, the first crewed NASA mission to set foot on the Moon in more than 50 years, will be a historic mission, returning astronauts to the Moon for the first time since Apollo 17 in 1972.

Axiom Space has partnered with Nokia to integrate advanced 4G/LTE communication capabilities into the next-generation spacesuits for the Artemis III lunar mission.

These spacesuits, known as the Axiom Extravehicular Mobility Unit (AxEMU), will support HD video, telemetry data, and voice transmission over multiple kilometers on the Moon. This advancement will allow Artemis III crewmembers to capture real-time video and communicate with mission controllers on Earth while exploring the lunar surface.

Texas, US-headquartered privately funded space infrastructure developer, Axiom Space, has selected Nokia’s Lunar Surface Communications System (LSCS) for integration into its AxEMU spacesuits, which Artemis III astronauts will wear as they work on the lunar surface.

In its collaboration with Axiom Space on the Artemis III lunar spacesuit, Nokia intends to prove that the same cellular technologies that connect billions of devices on Earth can meet the critical communications needs of these seminal missions.

Together, Nokia and Axiom Space will incorporate high-speed cellular-network capabilities in AxEMU, supporting HD video, telemetry data and voice transmission over multiple kilometers on the Moon. This advancement will enable Artemis III crewmembers to capture real-time video and communicate with mission controllers on Earth while they explore the lunar surface.

The ability to transmit HD video and telemetry data over longer distances will facilitate scientific research, exploration, and documentation. Astronauts can share their experiences and findings with experts back on Earth.

Noki plans to deploy the first cellular network on the Moon as part of Intuitive Machines’ IM-2 mission, which is scheduled to be delivered to the launch site in this year only.

The Lunar Surface Communications System (LSCS)

Nokia’s Lunar Surface Communications System (LSCS), pioneered by Nokia Bell Labs’ research and innovation, will be deployed during IM-2 and will be further adapted for use in the AxEMU spacesuit.

While it is a 4G/LTE system at its heart, it is quite different to any cellular network on Earth.

4G/LTE Space Hardware

Nokia Bell Labs completely reconceptualized the hardware and software design of a 4G/LTE network, we experience on the Earth, to prepare the system for the unique operating parameters of a lunar mission and the harsh conditions of the Moon’s surface.

The LCS has been carefully engineered to withstand the extreme environmental conditions on the lunar surface, including radiation, extreme temperature variations and the Moon’s complete lack of atmosphere.

Finally, the equipment is designed to withstand the dynamic stresses of launch, spaceflight and lunar landing, as well as to meet Artemis III’s rigorous weight, size and power limitations.

Notably, the LSCS is the result of nearly two decades of research and innovation into automation, optimization, miniaturization and hardware and software integration. Nokia Bell Labs completely reconceptualized the hardware and software design of a terrestrial 4G/LTE network to prepare the system for the unique operating parameters of a lunar mission and the harsh conditions of the Moon’s surface.

The LSCS has two main components. First, a network-in-a-box combines the radio, base station, routing, security and core elements of a terrestrial network into a single highly resilient unit that will be integrated into the HLS. Second, device modules will be integrated into Axiom Space’s AxEMU spacesuits, providing mobile voice and broadband connectivity up to two kilometers away from the Artemis III human landing system (HLS).

The LSCS network system software is highly integrated and optimized, creating an extremely compact system that is fully autonomous and capable of self-deploying, self-configuring and self-healing.

As lunar missions become more frequent, this collaboration between Axiom Space and Nokia sets a precedent for developing lunar communication infrastructure. Future missions may build upon this technology or explore even more advanced communication systems.

Boeing’s Rockets Are Built with Inexperienced and Untrained Workforce, Reports NASA's Inspector General

A recent report has highlighted significant issues with Boeing's workforce involved in rocket production. The report, issued by NASA's inspector general, points out that Boeing's quality control practices at the Michoud Assembly Facility in Louisiana are lacking. This is largely due to the workforce having insufficient aerospace production experience.

The lack of a qualified workforce has led to numerous "Corrective Action Requests" and has caused delays and increased costs for the Space Launch System (SLS) rocket program. For instance, unsatisfactory welding operations resulted in propellant tanks that did not meet specifications, causing a seven-month delay.

These findings are concerning, especially given the importance of the SLS rocket for NASA's Artemis program, which aims to return humans to the Moon.

The Space Launch System (SLS) is NASA's super heavy-lift launch vehicle designed for deep space exploration. It is a key component of NASA's Artemis program, which aims to return humans to the Moon and eventually send astronauts to Mars.

The audit was performed, by the NASA Inspector General, because the SLS’s new upper stage — the Exploration Upper Stage (EUS)— is a critical component of the SLS upgrade, which is being done by the Boeing Company.

Once completed, the EUS will give the SLS a 40% upgrade in capability to send the Orion Multi-Purpose Crew Vehicle capsule and large cargos to the Moon, from 27 metric tons under Block 1—the SLS rocket’s first iteration—to 38 metric tons with Block 1B.

According to Safety and Mission Assurance officials at NASA and DCMA officials at Michoud, Boeing’s quality control issues are largely caused by its workforce having insufficient aerospace production experience," the report states. "The lack of a trained and qualified workforce increases the risk that the contractor will continue to manufacture parts and components that do not adhere to NASA requirements and industry standards."

This lack of a qualified workforce has resulted in significant program delays and increased costs. According to the new report, "unsatisfactory" welding operations resulted in propellant tanks that did not meet specifications, which directly led to a seven-month delay in the program.

Notably, SLS is the only rocket capable of sending the Orion spacecraft, astronauts, and large cargo directly to the Moon in a single mission. The rocket has multiple configurations, with the initial Block 1 capable of lifting 95 metric tons to low Earth orbit (LEO) and future versions (Block 1B and Block 2) designed to carry even heavier payloads.

The SLS will support various missions, including crewed lunar landings, deep space exploration, and potentially missions to Mars.

The SLS represents a significant advancement in space exploration technology, combining power, versatility, and the capability to support long-duration missions beyond Earth's orbit.

NASA Inspector general's report has projected that SLS Block 1B costs will reach approximately $5.7 billion before the system is scheduled to launch in 2028. This is $700 million more than NASA’s 2023 Agency Baseline Commitment, which established a cost and schedule baseline at nearly $5 billion.

EUS development accounts for more than half of this cost, which the report estimates will increase from an initial cost of $962 million in 2017 to nearly $2.8 billion through 2028. Boeing’s delivery of the EUS to NASA has also been delayed from February 2021 to April 2027, and when combined with other factors, suggests the September 2028 Artemis IV launch date could be delayed as well.

ISRO, ESA and NASA Team Up to Study Asteroid Apophis During Its 2029 Flyby

An asteroid, named after Egyptian deity of destruction, — Apophis — will come remarkably close to Earth during its flyby in 2029. At its closest approach, it will be about 19,000 miles (30,500 kilometers) from our planet's surface. To put this in perspective, that's closer than some of our geostationary satellites.

This close encounter provides a unique and rare opportunity for detailed observations and scientific study. Space agencies of USA and Europe – NASA and ESA – are gearing up to learn more about this intriguing asteroid.

In a latest now Indian Space Research Organisation (ISRO), ESA and NASA have team up to Study Asteroid Apophis During Its 2029 Flyby. 

Asteroid 99942 Apophis is a near-Earth object (NEO) estimated to be about 1,100 feet (335 meters) across. Initially considered one of the most hazardous asteroids, its impact assessment changed after precise orbit analysis. Recent radar observations ruled out any impact risk for at least a century, including the close approaches in 2029 and 2036.

ESA's Rapid Apophis Mission for Space Safety (Ramses) mission aims to closely study Apophis during its safe but exceptionally close flyby of Earth in 2029. Ramses will provide valuable insights into this large asteroid, enhancing our preparedness for future asteroid threats.

NASA already has a probe to study Apophis after its 2029 flyby, complementing ESA's efforts.

While ISRO is not directly involved in the collaborative study of asteroid Apophis in 2029, their contributions to space exploration and scientific research are noteworthy. ISRO is India's national space agency, known for its successful satellite launches, lunar missions (such as Chandrayaan-2), and Mars Orbiter Mission (Mangalyaan). The Indian Space agency has expertise in remote sensing, communication
satellites, and interplanetary exploration.

However, according to reports ISRO may send its own spacecraft or collaborate with NASA and ESA to enhance the overall mission's scientific return. The Indian Space agency plans to observe Apophis during its 2029 flyby, though specific mission details are still under consideration.

ISRO has emphasized the real possibility of an asteroid impact on Earth, and the space agency is actively working on planetary defense efforts.

ISRO continues to expand its capabilities, and future collaborations may involve joint efforts in planetary defense and space science

Remember, space exploration is a collective endeavor, and each agency's contributions enhance our understanding of the cosmos.
