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. The two-day summit brought together a confluence of ideas from global thought leaders, intellectuals, and change-makers, covering transformative possibilities in science, medicine, social contracts, and global leadership, with experts from diverse fields offering bold visions of a better, more sustainable world for all.

Sunita Williams and Butch Wilmore Returning to Earth Next Month

Sunita Williams and her crewmate Butch Wilmore are set to return to Earth earlier than expected. NASA has announced that they will be coming back aboard a SpaceX Crew Dragon capsule in mid-March 2025. Their return was delayed due to technical issues with the Boeing Starliner capsule, which extended their stay on the ISS to over eight months

Williams and Wilmore have been conducting important research and even took part in spacewalks during their extended missio. Despite the challenges, they've remained in good spirits and assured everyone that they are safe and well-supplied.

During her extended stay on the ISS, Sunita Williams conducted several important research projects. One notable study focused on preventing cartilage damage and boosting bone strength in astronauts during long space missions. This research involved jumping exercises, which showed promising results in maintaining joint health and preventing cartilage degradation in mice. The findings suggest that similar exercises could be beneficial for astronauts on future long-duration missions, such as those to Mars.

Williams has faced several challenges, including muscle atrophy, bone density loss, and appetite-related weight loss due to prolonged exposure to microgravity. Despite these difficulties, she has continued to perform crucial tasks outside the ISS and conduct scientific research.

Spacewalk Record by Sunita

During this time, Sunita has broken the record for the most cumulative spacewalking time by a female astronaut. On January 30, 2025, NASA astronaut Sunita Williams made history while floating 423 kilometers above the Pacific Ocean. During her 9th spacewalk outside the International Space Station (ISS), she captured a breathtaking selfie, marking a memorable moment in her space journey.

Williams also participated in various other experiments and maintenance tasks aboard the ISS, contributing to our understanding of how the human body adapts to prolonged space travel.

In their latest statement, Sunita Williams and Butch Wilmore reassured everyone that they are safe and well-supplied despite the extended stay on the ISS. Williams mentioned, "I don’t think I’m abandoned. I don’t think we’re stuck up here". She also addressed concerns about her appearance in recent images, explaining that the changes were due to the common effects of microgravity on bodily fluids.

They both expressed gratitude for the support and efforts to bring them back home and are looking forward to their return in mid-March 2025 aboard a SpaceX Crew Dragon capsule.

Effects of Long-Term Duration Stay in Space

Long-duration space missions have revealed several health effects on astronauts due to the unique environment of space. The lack of gravity in space leads to muscle atrophy and bone density loss. Astronauts can lose up to 1-2% of bone mass per month and experience muscle weakening.

Prolonged exposure to microgravity can cause changes in the cardiovascular system, including reduced heart muscle mass and fluid shifts that lead to a puffy face and bird legs syndrome (swelling of the legs and feet).

Space radiation, including galactic cosmic rays and solar particle events, poses significant risks. It can increase the risk of cancer and cause damage to the central nervous system.

Some astronauts experience visual impairment intracranial pressure (VIIP), which includes swelling of the optic nerve, changes in eye shape, and degraded vision.

Besides, the isolation, confinement, and distance from Earth can lead to psychological stress, including sleep disturbances, mood changes, and cognitive decline.

Spaceflight can alter the immune system, making astronauts more susceptible to infections and reducing their ability to fight off pathogens.

Long-term exposure to space radiation can lead to cancer and genetic damage.

These health effects highlight the importance of developing countermeasures and technologies to ensure the safety and well-being of astronauts on future long-duration missions.
