NASA pulls Crew-11 from ISS in first medical evacuation as SpaceX Dragon heads for splashdown

NASA pulls Crew-11 from ISS in first medical evacuation as SpaceX Dragon heads for splashdown

CAPE CANAVERAL, Florida, Jan 15, 2026, 01:41 (EST) Late Wednesday, a SpaceX Dragon capsule carrying four astronauts undocked from the International Space Station, marking NASA’s first medical evacuation from the orbiting lab following a crew member’s health issue. The decision trims the Crew-11 mission by about a month, leaving the station with fewer crew members until the next rotation. It’s…

NASA’s Moon Nuclear Reactor Push Meets DOE Safety Rule Shake-Up — What Space and Nuclear Stocks Are Watching

NASA’s Moon Nuclear Reactor Push Meets DOE Safety Rule Shake-Up — What Space and Nuclear Stocks Are Watching

WASHINGTON, January 14, 2026, 03:25 EST NASA and the U.S. Department of Energy announced plans to develop a nuclear reactor for the Moon’s surface by 2030, reviving a partnership that places fission power at the heart of America’s lunar ambitions. Why it matters now: a reactor could provide a reliable power source during the Moon’s long periods of darkness, a…

SpaceX Falcon 9 lifts off with 29 Starlink satellites as FCC clears bigger buildout

CAPE CANAVERAL, Florida, Jan 9, 2026, 19:27 EST SpaceX launched 29 Starlink internet satellites into orbit on Friday on a Falcon 9 rocket from Cape Canaveral, Florida. The first-stage booster landed at sea on the droneship A Shortfall of Gravitas after stage separation, and SpaceX later confirmed the satellites were deployed. Spaceflightnow The flight came as U.S. regulators moved to…

Alien Talk Fades Around Interstellar Comet 3I/ATLAS as New Searches Find No Signals and Images Turn Green

Alien Talk Fades Around Interstellar Comet 3I/ATLAS as New Searches Find No Signals and Images Turn Green

WASHINGTON, January 7, 2026, 21:00 EST Astronomers scanning interstellar comet 3I/ATLAS for signs of alien technology came up empty, a result that adds weight to the case that the fast-moving visitor is natural, not a spacecraft. That matters now because 3I/ATLAS is only the third object ever confirmed to have entered the solar system from interstellar space, and it is…

Europa Clipper’s UV look at Comet 3I/ATLAS backs water-ice call as radio “technosignature” scan finds none

Europa Clipper’s UV look at Comet 3I/ATLAS backs water-ice call as radio “technosignature” scan finds none

WASHINGTON, January 7, 2026, 14:24 (EST) NASA’s Europa Clipper spacecraft caught interstellar comet 3I/ATLAS in ultraviolet light while the object was hidden from Earth-based and near-Earth observatories, the SETI Institute said on Tuesday. It detected hydrogen and oxygen in the comet’s coma — the cloud of gas around its nucleus — pointing to water-ice sublimation, and saw no sign the…

Moon rush 2026: Blue Origin, Firefly, Intuitive Machines and Astrobotic line up lunar landings

Moon rush 2026: Blue Origin, Firefly, Intuitive Machines and Astrobotic line up lunar landings

Seattle, Jan 6, 2026, 05:14 (PST) Private lunar landings are back on the calendar for 2026, with Blue Origin, Firefly Aerospace, Intuitive Machines and Astrobotic lining up robotic missions to the Moon. The run of attempts would add fresh pressure to prove that commercial lunar delivery can work more than once. The push comes as NASA prepares Artemis II, a…

Alien-signal hunt finds nothing from interstellar comet 3I/ATLAS after Green Bank scan

Alien-signal hunt finds nothing from interstellar comet 3I/ATLAS after Green Bank scan

NEW YORK, Jan 5, 2026, 04:15 ET A search for possible technosignatures — potential signs of advanced technology — in the interstellar comet 3I/ATLAS found no credible radio transmissions, Breakthrough Listen researchers reported. The team said its campaign detected no candidate signals down to the 100 milliwatt level. arXiv The finding matters because 3I/ATLAS is a rare visitor from outside…

Interstellar comet 3I/ATLAS vents water after Sun swing-by as radio search finds no signals

Interstellar comet 3I/ATLAS vents water after Sun swing-by as radio search finds no signals

NEW YORK, January 4, 2026, 18:22 ET Scientists tracking interstellar comet 3I/ATLAS with a Sun-watching spacecraft have estimated how quickly it shed water after its late-October pass around the Sun, before activity eased as it moved outward. A separate radio scan also reported no sign of artificial transmissions from the object. (https://ts2.tech/en/soho-spots-water-gushing-from-interstellar-comet-3i-atlas-after-its-sun-pass/) The readings matter because 3I/ATLAS — only the…

Scientists Scanned Interstellar Comet 3I/ATLAS for Alien Signals — and Found Nothing

NEW YORK, January 4, 2026, 05:41 ET Scientists hunting for signs of alien technology from interstellar comet 3I/ATLAS reported no radio signals that could be traced to the object, after aiming one of the world’s most sensitive dishes at it during its recent close pass by Earth. ScienceAlert The result matters because 3I/ATLAS is rare — only the third known…

Green Bank Telescope schedules fresh scan of interstellar Comet 3I/ATLAS as it heads out

Green Bank Telescope schedules fresh scan of interstellar Comet 3I/ATLAS as it heads out

NEW YORK, January 3, 2026, 10:19 ET The Green Bank Telescope in West Virginia scheduled a six-hour “chemical survey” of interstellar comet 3I/ATLAS early on Saturday, according to the facility’s public observing schedule. The slot ran from 01:30 to 07:00 ET and used a high-frequency receiver band commonly used to hunt for molecular fingerprints. The timing matters because 3I/ATLAS —…

  • Alphabet Shares Fall 2.4% Amid Mixed AI Sentiment and Market Tensions
    January 20, 2026, 8:57 PM EST. Alphabet Inc. (NASDAQ: GOOGL) shares declined 2.4% to $322 on Tuesday amid heightened trading volume. The drop came despite recent positive analyst upgrades and strong sales of Google's Gemini AI models, which have boosted long-term revenue expectations. Alphabet's entry into the $4 trillion market cap club reflects its AI-driven strategy but currently acts more as a thematic support than an immediate catalyst. Market concerns persisted due to geopolitical tensions affecting tech stocks broadly and a delayed clinical trial for Alphabet-backed Isomorphic Labs, dampening near-term biotech hopes. Analysts maintain mostly bullish outlooks with price targets ranging from $315 to $370, citing secular growth from AI and cloud. However, sector rotation and divergence among mega-cap tech names present risks to Alphabet's short-term performance.
