NASA Astronaut Jonny Kim Returns to Earth After 245-Day Space Mission

NASA astronaut Jonny Kim, along with Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, has safely returned to Earth after completing a 245-day mission aboard the International Space Station (ISS). The crew landed in Kazakhstan after departing the ISS on the Soyuz MS-27 spacecraft. During their mission, they conducted various scientific experiments, including studies on bioprinted tissues and remote robotic command. This mission marked the first spaceflight for Kim and Zubritsky, while Ryzhikov completed his third space journey.

NASA Investigates MAVEN Spacecraft Signal Loss at Mars

NASA Investigates MAVEN Spacecraft Signal Loss at Mars

NASA's MAVEN spacecraft, which is orbiting Mars, experienced a loss of signal with Earth-based ground stations on December 6. Prior to the signal loss, telemetry indicated that all subsystems were functioning normally. The signal was lost when MAVEN orbited behind Mars, and it did not re-establish contact upon re-emerging. NASA's Deep Space Network is currently working with the spacecraft and operations teams to investigate the anomaly and restore communication. MAVEN, launched in 2013, has been studying Mars' upper atmosphere and its interactions with solar wind to understand atmospheric loss.

University of Surrey Proposes Space Junk Recycling to Address Orbital Debris

University of Surrey Proposes Space Junk Recycling to Address Orbital Debris

Researchers at the University of Surrey have published a paper proposing a comprehensive approach to managing space junk through recycling and repurposing. The study suggests using existing technologies like AI collision avoidance systems and repurposing space stations for recycling space debris. The concept, although familiar on Earth, is relatively new to the space industry. The paper highlights the growing problem of space debris, with over 25,000 pieces larger than 4 inches orbiting Earth, posing risks to satellites and global communications. The proposal aims to create a sustainable system by coordinating technologies and designing satellites for easier end-of-life disposal.

University of Surrey Proposes Systemic Space Recycling to Combat Space Junk

University of Surrey Proposes Systemic Space Recycling to Combat Space Junk

Researchers at the University of Surrey have published a paper proposing a comprehensive approach to managing space debris, which is accumulating at an alarming rate. The paper suggests making space operations more sustainable by using less material, repairing existing satellites, and recycling space junk that cannot be repaired. This approach aims to address the growing problem of space debris, which includes over 25,000 pieces larger than 4 inches in diameter and millions of smaller fragments. The accumulation of space junk poses significant risks, such as the Kessler Syndrome, where collisions could create a cascade of debris, rendering parts of space unusable. The paper emphasizes the need for industry-wide systemic changes rather than relying solely on individual technological solutions.

NASA Warns of Satellite Contamination in Space Telescope Images

NASA Warns of Satellite Contamination in Space Telescope Images

NASA has issued a warning about the potential contamination of space telescope images due to the increasing number of satellites in low Earth orbit. The proliferation of satellite internet services, such as SpaceX's Starlink, has led to a dramatic rise in satellite numbers, posing a threat to astronomical observations. Simulations show that reflected light from satellites could affect up to 96% of images taken by certain space telescopes, impacting scientific research and the detection of celestial objects.

Soyuz MS-27 Crew Prepares for Return to Earth from International Space Station

Soyuz MS-27 Crew Prepares for Return to Earth from International Space Station

The Soyuz MS-27 spacecraft, carrying NASA astronaut Jonny Kim and Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, is set to undock from the International Space Station (ISS) and return to Earth. The undocking is scheduled for approximately 8:41 p.m. EST, with a parachute-assisted landing expected at 12:03 a.m. on December 9, 2025, in Kazakhstan. NASA is providing live coverage of the event on multiple platforms, including NASA+, Amazon Prime, and YouTube. This marks the conclusion of an eight-month mission focused on space research and international collaboration aboard the ISS.

NASA Astronaut and Roscosmos Cosmonauts Prepare for Departure from International Space Station

NASA astronaut Jonny Kim, along with Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, are set to depart the International Space Station (ISS) aboard the Soyuz MS-27 spacecraft. The crew will close the hatch between the spacecraft and the ISS at 5:10 p.m. EST, with undocking scheduled for approximately 8:41 p.m. The spacecraft is expected to land in Kazakhstan at 12:04 a.m. on December 9, local time. This mission marks the first spaceflight for both Kim and Zubritsky, while Ryzhikov concludes his third mission, bringing his total time in space to 603 days, ranking him 13th all-time. The crew's mission lasted 245 days, during which they orbited Earth 3,920 times and traveled nearly 104 million miles.

NASA Monitors Plane-Sized Asteroid Approaching Earth at Safe Distance

NASA Monitors Plane-Sized Asteroid Approaching Earth at Safe Distance

NASA is tracking an asteroid named '2025 XM' as it approaches Earth, expected to pass within 295,000 miles today. The asteroid, traveling at 9,753 miles per hour, measures approximately 84 feet in diameter, comparable to a commercial airplane. Despite its proximity, 2025 XM does not meet NASA's criteria for a potentially hazardous object, which requires a diameter of over 150 meters and a closer approach. This asteroid is one of several passing near Earth this week, including '2019 XN3' and '1999 SF10', which will pass at greater distances.
