NASA's 47-year-old Voyager 1 spacecraft, currently 15 billion miles away in interstellar space, experienced a brief communication interruption on October 16. Engineers at Jet Propulsion Laboratory re-established contact on October 24 using a radio transmitter last used in 1981. The outage occurred when Voyager 1's fault protection system switched to a lower-power transmitter. Signals take 23 hours to travel between Earth and the spacecraft. Investigation revealed the system's automatic power-down triggered the shutdown. Successful reconnection ensures continued transmission of vital data from the historic spacecraft.

India's space agency, ISRO, has launched its first analog space mission in Leh, Ladakh, to study the challenges of extraterrestrial conditions. The mission includes a compact, inflatable habitat named Hab-1, simulating life in an interplanetary habitat to tackle challenges of a base station beyond Earth. This groundbreaking project, developed in collaboration with ISRO's Human Spaceflight Centre, the University of Ladakh, IIT Bombay, and Aaka Space Studio, will help understand challenges future astronauts may face on missions beyond Earth. Key objectives include testing human endurance, advanced habitat designs, biometric data collection, and life support systems.

NASA's Voyager-1 spacecraft, launched in 1977, briefly lost contact with Earth due to a technical issue. On October 16, a command to activate a heater triggered the spacecraft's fault protection system, shutting down its primary X-band transmitter. The system automatically switched to a backup S-band transmitter, last used in 1981. NASA's Jet Propulsion Laboratory team successfully reestablished communication on October 24, overcoming challenges posed by the weaker signal traveling 25 billion kilometers from Earth. The incident demonstrated Voyager-1's resilience and NASA's expertise in maintaining communication with the 45-year-old probe.

NASA astronaut Sunita Williams, currently stationed on the International Space Station (ISS), shared heartfelt Diwali greetings from space. In a video message, she expressed gratitude to U.S. President Joe Biden and Vice President Kamala Harris for celebrating Diwali at the White House, recognizing the Indian community’s contributions. Williams, who has been aboard the ISS since June, reflected on her cultural heritage and the significance of Diwali. Originally planned as a short mission, her stay was extended, with her return expected in February. Williams shared, “Diwali is a time of joy as goodness in the world prevails.”

ISRO Chief S Somanath has announced updated timelines for India’s upcoming space missions. The Chandrayaan-4 mission, aimed at returning lunar samples, is scheduled for 2028. The Chandrayaan-5 mission, a collaborative moon landing with Japan’s JAXA, is also expected after 2028, carrying a 350-kg rover, ten times heavier than Chandrayaan-3’s. India’s first manned mission, Gaganyaan, is planned for 2026, with future goals set for a moon mission by 2040. Additionally, ISRO will launch the TDS-01 electric-propelled satellite in December 2024. Somanath shared these updates at the Sardar Patel Memorial Lecture, highlighting India’s space advancements.

A NASA astronaut has been hospitalized after returning to Earth from a 235-day mission on the International Space Station (ISS). The unnamed astronaut was taken to Ascension Sacred Heart Pensacola hospital for an undisclosed medical issue, with NASA emphasizing caution. Three other crew members, including two NASA astronauts and one Russian cosmonaut, were released from the hospital and have since returned to Houston. The mission’s return, originally delayed by Boeing's Starliner capsule issues and weather conditions, finally concluded with a safe splashdown in the Gulf of Mexico. NASA described the astronaut’s condition as stable and under observation.

On October 22, 2024, a 3-foot-wide asteroid, designated 2024 UQ, struck Earth’s atmosphere over the Pacific Ocean just hours after its discovery. The impact occurred about 1,000 km off the California coast, creating a bright fireball that was detected by NASA’s Center for Near Earth Object Studies (CNEOS) at 3:54 am PT. Surveys like ATLAS and Catalina are increasingly able to detect such space rocks before impact, although no sightings were reported from land. This marks the third time in 2024 that an asteroid was discovered mere hours before striking Earth, with no harm caused.

After nearly eight months on the International Space Station (ISS), four astronauts—three Americans and one Russian—returned to Earth on Friday. The SpaceX capsule carrying the crew landed safely in the Gulf of Mexico near Florida. Originally scheduled to return two months ago, the mission faced delays due to Boeing's Starliner capsule issues and Hurricane Milton. NASA’s Matthew Dominick, Michael Barratt, and Jeanette Epps, along with Russia's Alexander Grebenkin, finally undocked mid-week. Their replacements include Starliner test pilots Butch Wilmore and Sunita Williams, along with two others, ensuring the ISS returns to its regular crew of seven.

NASA's Crew-8 mission has begun its 34-hour return to Earth after six months aboard the International Space Station. The SpaceX Dragon capsule, carrying NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Russian cosmonaut Alexander Grebenkin, undocked from the ISS at 2:40 am (IST) on Thursday. Their return had been delayed by poor weather conditions. The crew is expected to splash down near the Florida coast at around 1 pm (IST) on Friday. This marks the end of their mission, which involved various scientific experiments and maintenance activities during their time in space.
