Volatile sunspot fires 21 major flares in 24 hours as region turns Earth‑ward

In a 24‑hour period a rapidly growing sunspot produced at least 18 M‑class flares and three X‑class flares — including an intense X8.3 eruption — as the active region rotates into an Earth‑facing position. The concentrated burst elevates near‑term space‑weather monitoring for satellites and HF/GNSS services.

JPL used Anthropic’s Claude AI to map a 450‑m driving path for Perseverance on Mars Engineers at JPL successfully used Anthropic’s Claude AI to map a 450‑meter driving path for NASA’s Perseverance rover on Mars. The demonstration applied a commercial AI model to planetary‑surface route planning and produced a navigable traverse mission planners can use for upcoming drives.

NASA begins 49‑hour Artemis II wet dress rehearsal, fuels SLS ahead of simulated Feb. 2 liftoff NASA began a 49‑hour wet dress rehearsal at Kennedy Space Center on Jan. 31 for Artemis II, powering up and fueling the SLS core in a full practice countdown. The test—including a simulated liftoff targeted for 9 p.m. ET Feb. 2—is the final major check before a four‑astronaut lunar flyby.

Time puts Artemis II crew on a 'Back to the Moon' cover Time magazine put the Artemis II astronauts on a commemorative "Back to the Moon" cover, framing the crewed mission as a potential cultural touchstone. The feature invokes Apollo 8's role in 1968 and suggests Artemis II could exert similar social and symbolic impact today.

Galileo NIMS archival data reveal first ammonia-bearing compounds on Europa Reanalysis of Galileo NIMS archival data has revealed the first spectral evidence of ammonia-bearing compounds on Europa's surface, concentrated in fracture regions. The finding implies altered ocean chemistry and recent subsurface-to-surface exchange, reshaping target selection and science goals for upcoming missions to assess habitability.
