NASA Loses Signal from Critical Mars Orbiter

NASA's Chandra telescope has employed a novel technique known as 'X-arithmetic' to uncover how black holes influence the formation and evolution of galaxy clusters. This innovative approach allows scientists to analyze complex data and gain insights into the gravitational effects of black holes on their surrounding environments.

NASA astronaut Jonny Kim has returned to Earth after an extensive eight-month mission aboard the International Space Station (ISS), during which he completed 3,920 orbits around the planet. This mission concluded on December 9, 2025, marking a significant achievement in his career and contributions to space exploration.

NASA has lost contact with its MAVEN Mars orbiter while it was on the far side of the Red Planet. The communication link was abruptly severed, raising concerns about the status of the spacecraft, which had been operational for over a decade prior to this incident.

NASA's Perseverance rover has successfully collected significant samples from Mars, yet the mission to return these samples to Earth is encountering substantial obstacles that could delay or complicate the process.

NASA's Perseverance rover has captured audio evidence of lightning-like discharges in the thin atmosphere of Mars, marking a significant advancement in understanding the planet's atmospheric phenomena. This discovery allows scientists to hear dust devils crackling with electricity, providing new insights into Martian weather patterns.

Astronomers using NASA's James Webb Space Telescope (JWST) have identified the most ancient supernova ever observed, dating back to a time when the universe was less than a billion years old. This discovery marks a significant milestone in understanding the early universe and the formation of celestial bodies.

NASA astronaut Jonny Kim and Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky successfully landed on Earth aboard the Soyuz MS-27 on December 9, 2025, concluding a 245-day mission at the International Space Station (ISS). This return marks the end of their extensive scientific research and collaboration in orbit.
