Reusable Unmanned Drone Launched for Space Experiments by US Air Force

The US Air Force on Sunday successfully launched its high-tech drone X-37B, which is called highly secretive mission. Launched on an Atlas V rocket, the lift-off placed the reusable unmanned drone into orbit for its sixth secretive mission in space. The autonomous spacecraft X-37B was lofted into orbit from Cape Canaveral Air Force Station in Florida.

The drone will deploy a small research satellite dubbed FalconSat-8, to carry out additional experiments, Secretary of the Air Force Barbara Barrett, which has been overseeing the X-37B program, explained earlier this month.

Weighing 300 pounds, the FalconSat-8 satellite is the size of a small refrigerator and carries high-tech gear, including an experimental thruster to propel it through space and a cutting-edge antenna that will test whether new, compact antenna designs can work as well in space as their larger cousins.



“This X-37B mission will host more experiments than any prior missions," said Barrett, who also heads the recently created US Space Force.

The liftoff was announced by Barbara Barrett on her Twitter profile page -



Began as a NASA project in 1999, the X-37 is now operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120-percent-scaled derivative of the earlier Boeing X-40.

The unmanned and robotic spacecraft, which looks like a mini space shuttle, has been a secretive Air Force project for years. It is a reusable robotic spacecraft boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane.

History

In 1999, NASA selected Boeing Integrated Defense Systems -- a division of The Boeing Company responsible for defense and aerospace products and services -- to design and develop an orbital vehicle.

Built by the California branch of Boeing's Phantom Works, the X-37 was transferred from NASA to the Defense Advanced Research Projects Agency (DARPA) on 13 September 2004. Phantom works is the advanced prototyping arm of the Boeing Company that develops advanced military products and technologies, many of them highly classified and secretive.

Between year 1999 and 2003, a total of US$192 million was spent on the project, with NASA contributing $109 million, the U.S. Air Force $16 million, and Boeing $67 million. In late 2002, a new $301-million contract was awarded to Boeing as part of NASA's Space Launch Initiative framework.

Previous Launches of X-37

According to the Wikipedia page, the X-37's first mission was launched in April 2010 and returned to Earth in December 2010. A second X-37 was launched in March 2011 and returned in June 2012. The third mission was launched in December 2012 and landed in October 2014. The fourth mission was launched in May 2015 and landed in May 2017. The fifth X-37 mission, which is the longest X-37 to date, was launched on 7 September 2017 and landed back to the Earth on 27 October 2019 after 780 days in orbit.

India Plans High-Tech Warfare with 5 New DRDO Labs focusing AI, Quantum, Cognitive Tech & Smart Materials

Representative

India has set sight over high-tech warfare as state-owned military research & development agency, Defence Research and Development Organisation (DRDO), has announced that it has launched five new laboratories known as Young Scientists laboratories, each focusing core areas of futuristic technologies including Artificial Intelligence (AI), Quantum Technologies, Cognitive Technologies, Asymmetric Technologies and Smart Materials -- object which can change shape, size and behavior upon external stimuli.

These five new defence labs under the DRDO, formally launched on Thursday by PM Narendra Modi, are located in Bengaluru, Mumbai, Chennai, Kolkata and Hyderabad. These labs will be led by under-35 directors and young military scientists to drive India's warfare technologies of the future.

Jadavpur University campus in Kolkata will have research lab of futuristic area of Asymmetric Technologies. While, the research in hot and critical area of Smart Materials and their applications will be based out of Hyderabad. Research in the area of Artificial Intelligence will be carried out at Bengaluru, while the all-important area of Quantum Technology will be based out of IIT Mumbai.

In the area of cognitive technologies research, IIT Madras will house the lab for the same.

To recall, in 2018 a govt. of India initiated task force led by Tata Sons Chairman N. Chandrasekaran handed over the report to the Indian defence minister for implementation of its recommendations on using AI for military superiority.

While AI and Quantum computing are familiar to tech enthusiasts, Asymmetric technolgies and smart materials are quite new and described in brief as below -

Asymmetric technologies, in our understanding, refers to technologies involved in war between enemy or entity that acts in a hostile manner and whose relative military power/strategy/ tactics differs significantly. Asymmetric warfare is a form of irregular warfare and the term is also frequently used to describe what is also called "guerrilla warfare", "insurgency", "counterinsurgency", "rebellion", "terrorism", and "counter-terrorism", essentially violent combat between a formal military and an informal, less equipped and supported, undermanned but resilient and motivated opponent.

Smart Materials are objects that can change shape or behaviors with hot water, pressure, chemical, light or heat. Essentially, these materials sense and react to environmental conditions or stimuli (e.g., mechanical, chemical, electrical, or magnetic signals). Smart materials are said to be beneficial for industries such as aerospace, medical, textile, construction, and electronics as it improve efficiency and save resources by responding to corrosion, pH changes, water content, temperature, mechanical forces, and much more.

These smart materials could even self-assemble when one touches them. When a stimulus is applied on such a smart object, it is possible to transform into a brand new shape as these materials are reacting to their external environment.

Cognitive Technologies, on other hand, extend the power of information technology to tasks traditionally performed by humans, such technology can mimic functions of the human brain through various means, including natural language processing, data mining and pattern recognition.

High-Tech Warfare Programs of US & China

While DRDO is India's military research body, the analogous of same in the United States is DARPA (Defense Advanced Research Projects Agency), which has developed several futuristic technologies and warfare systems way beyond imaginations to countries in south-east Asia. While cognitive tech research are being done since 2002 by the US agency, asymmetric warfare technologies is said to be first introduced by DARPA in 1960s used for fighting Communist insurgents in Vietnam and Thailand.

DARPA is working on 'Sensor plants' which uses plants to gather intelligence information" through DARPA's Advanced Plant Technologies (APT) program, which aims to control the physiology of plants in order to detect threats including chemical, biological, radiological and nuclear threats.

DARPA is also said to be working on creating a ‘black box’ for brain, which is much like the black box used in airplanes. The microchip implanted in brain will record every moment and make it possible to obtain information one's final moments.

The Chinese counterpart of DARPA is considered to be COSTIND (Commission for Science, Technology and Industry for National Defense), which aims to facilitate the transfer of technology between the military and civilian sectors and has played an important role in China's space program.
