<p>NASA has warned of two massive asteroids will make their closest approach on Monday (December 16, 2024). These celestial bodies are named 2024 XY5 and 2024 XB6. They are racing towards Earth at incredible speeds. Although NASA has confirmed that neither poses a danger to our planet. These near-Earth objects (NEOs) highlight the importance of vigilant monitoring by space agencies.</p></p>

It will make its closest approach to Earth at 12:26 AM IST on Monday, passing within 2,180,000 miles—about 16 times the average distance between Earth and the Moon.

<p>During a recent press conference, it was revealed that NASA is grappling with an unforeseen situation, which has led astronauts Sunita Williams and Barry&nbsp;Wilmore to get stuck on the International Space Station (ISS) as they wait for their return to Earth. What was supposed to be a short mission of two months has now been extended till at least February 2025.</p>

<p>NASA astronauts Williams and Wilmore took off aboard Boeing's Starliner on June 5 and reached their destination, the ISS, on June 6.</p>

<p>According to the schedule, they were supposed to return around mid-June. However, plans had to be adjusted after various issues, including the propulsion system, helium leaks, and thruster malfunction were detected in the Starliner’s capsule.&nbsp;</p>

<p>Ken Bowersox, associate administrator of NASA’s Space Operations Mission Directorate, said “We’re reaching a point where that last week in August we really should be making a call, if not sooner.”</p>

<p>This comes as the Starliner’s crew and authorities are focused on the safe return of the two astronauts to Earth. They are said to be trying their best to bring Williams and Wilmore back on Starliner. However, the option of using the SpaceX Dragon spacecraft for the return mission is also being considered, just to be on the safe side.</p>

<p>Joel Montalbano, deputy associate administrator of NASA’s Space Operations Mission Directorate, said astronauts prepare for every possibility before their human spaceflight.&nbsp;</p>

<p>He said, “Butch [Barry Wilmore] and Suni [Sunita Williams] said ahead of their launch that they know this mission might not be perfect. Human spaceflights are inherently risky, and as astronauts, we accept that.”&nbsp;</p>

<p>Montalbano said that if both astronauts did not return on Starliner, they would have to spend almost eight months in orbit. “They will have about eight months in orbit. If the two astronauts come on the SpaceX craft, they will return to Earth by February 2025,” he added.</p>

<p>Recently, NASA has conveyed that Starliner would not be used for the astronauts’ return.&nbsp;</p>

<p>However, SpaceX can be the possible choice for NASA’s Crew-9 mission to the ISS, which is scheduled for September 24. This will enable the two astronauts to return home by 2025.</p>

<p>In case&nbsp;of an emergency, there is a possibility that the two astronauts could be unsuited, said Montalbano.</p>

<p>When asked if the Starliner would be uncrewed or if any special equipment had been allotted for them, NASA said, “From a suits standpoint, they are not interchangeable. You can’t have a Boeing suit in SpaceX or a SpaceX suit in a Boeing vehicle, so that would not be the plan. If the Starliner undocks and only the Dragon is available, they might have to return unsuited on the Dragon.”&nbsp;</p>

<p>The extra SpaceX flight suits will be sent through the Crew-9 team, Montalbano said.&nbsp;</p>

Sunita Williams and Barry Wilmore could be stuck in space until Feb 2025. Here's why NASA is in a conundrum

<p>NASA is actively promoting ongoing scientific, educational, and technological advancements in low Earth orbit for the benefit of humanity, while simultaneously supporting deep space exploration efforts targeting the Moon and Mars. As the agency shifts towards commercially-operated space facilities in near-Earth orbit, it's vital to prepare for the safe and responsible deorbiting of the International Space Station (ISS) in a controlled manner after its operational life concludes in 2030.</p>

<p>NASA has announced that SpaceX has been chosen to develop and deliver the U.S. Deorbit Vehicle. This spacecraft will be responsible for safely deorbiting the space station, ensuring that it poses no risk to populated areas during re-entry.</p>

<p>Ken Bowersox, associate administrator for Space Operations Mission Directorate at NASA Headquarters in Washington, emphasised the importance of this decision. He stated that selecting a U.S. Deorbit Vehicle for the ISS will help NASA and its international partners ensure a safe and responsible transition in low Earth orbit as station operations come to an end. This decision also aligns with NASA's plans for future commercial destinations and supports the continued use of near-Earth space.</p>

<p>While SpaceX will develop the deorbit spacecraft, NASA will take ownership of it after development and operate it throughout its mission. The deorbit vehicle, along with the space station, is expected to break up during the re-entry process.</p>

<p>The International Space Station has been a collaborative effort since 1998, involving five space agencies: CSA (Canadian Space Agency), ESA (European Space Agency), JAXA (Japan Aerospace Exploration Agency), NASA, and Roscosmos. Each agency is responsible for managing and controlling the hardware it provides. The station's design is interdependent, relying on contributions from all partners to function.&nbsp;</p>

<p><br />
The United States, Japan, Canada, and participating ESA countries have committed to operating the station through 2030, while Russia has committed to continued operations through at least 2028. The safe deorbiting of the ISS is a shared responsibility among all five space agencies.</p>

<p>The contract awarded to SpaceX for the U.S. Deorbit Vehicle has a total potential value of USD 843 million. The launch service for this vehicle will be procured separately in the future.</p>

<p>Currently in its 24 year of continuous crewed operations, the ISS serves as a unique scientific platform. Crew members conduct experiments across various research disciplines, including Earth and space science, biology, human physiology, physical sciences, and technology demonstrations that are not possible on Earth. The station has facilitated over 3,300 experiments in microgravity, with crews acting as the hands of thousands of researchers on the ground.</p>

<p>The ISS has become a cornerstone of space commerce, fostering partnerships in commercial crew and cargo operations, as well as commercial and national lab research. The lessons learned aboard the International Space Station are instrumental in paving the way for future commercial stations, ensuring the continued advancement of human presence and scientific discovery in space. &nbsp;</p>

<p>In the video, the satellite shows the popularity of the sport through the lights. In a small tour, the US space agency grabbed a clear view where the station orbits Earth to catch the stadium's lights in Atlanta.&nbsp;</p>

<p>Meanwhile, Tom Brady won the Super Bowl for a sixth time as Patriots defeated the Los Angeles Rams 13-3 in a defence-dominated finale.</p>

<p>Brady, 41, became the first player ever to win six Super Bowls, 17 years after leading the Patriots to his first title in 2002.&nbsp;Patriots' wide receiver Julian Edelman won the Super Bowl MVP trophy.</p>

NASA scientists have chosen five green technology concepts that have the potential to transform the aviation industry in the next decade by reducing aircraft fuel usage and emissions by 75 per cent.<br />
<br />
The concepts were selected under NASA&#39;s Transformative Aeronautics Concepts Programme in the US for a two-year study.<br />
<br />
The topics, including three specifically targeted at electrically-propelled aircrafts are the use of alternative fuel cells, three-dimensional (3D) printing to increase electric motor output, lithium-air batteries for energy storage, new mechanisms for changing the shape of an aircraft wing in flight and a lightweight material called aerogel in the design and development of aircraft antenna.<br />
<br />
These five concepts, in addition to three of the six selected last year, address NASA&#39;s green aviation initiatives to cut fuel use by half, lower harmful emissions by 75 per cent, and significantly reduce aircraft noise, scientists said.<br />
<br />
&quot;There definitely was an emphasis in our selections on bringing forward activities that addressed a NASA aeronautics goal to reduce the carbon footprint of aviation during the 21st century,&quot; said programme manager Doug Rohn.<br />
