A new study suggests Earth may survive the Sun’s red giant phase by drifting outward as the star loses mass. The result conflicts with earlier research that predicted Earth would still be engulfed.
Launched in 1977, NASA's Voyager 1 spacecraft, now 25 billion km away, continues to send data from interstellar space. Despite a shrinking power supply and communication delays, it remains the most distant human-made object and is expected to transmit basic data into the 2030s.
NASA, in collaboration with L3Harris, is testing a 'cryocoupler' for in-orbit refueling of spacecraft, enabling future deep space missions to refuel before departure.
NASA's Deep Space Network (DSN) is struggling to meet the increasing data demands of its missions, particularly the Artemis lunar program. The network experienced strain during Artemis I and II, impacting science missions. To address this, NASA is developing new infrastructure like Lunar Exploration Ground Sites (LEGS) and exploring optical communications, while also facing challenges with a damaged 70-meter antenna at Goldstone.
The Artemis II crew has returned from a record-breaking mission beyond low Earth orbit. Experts highlight the significant physical challenges of deep space, including radiation exposure and microgravity effects, and how NASA monitors and mitigates these risks for future exploration.
