NASA Reestablishes Contact with Voyager 1 Spacecraft After Brief Communication Blackout

Brief by Shorts91 Newsdesk / 04:04am on 02 Nov 2024,Saturday Science

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.

ISRO Launches India's First Analog Space Mission in Ladakh to Simulate Life Beyond Earth

Brief by Shorts91 Newsdesk / 08:37am on 01 Nov 2024,Friday Science

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 Reestablishes Contact with Voyager-1 Spacecraft After Brief Communication Loss

Brief by Shorts91 Newsdesk / 06:15am on 31 Oct 2024,Thursday Science

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.

Asteroid Hits Near California After Last-Minute Discovery, Burns Bright Over Pacific Ocean

Brief by Shorts91 Newsdesk / 05:42pm on 25 Oct 2024,Friday Science

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.
