Shannon Airport Was Considered a NASA Space Shuttle Emergency Landing Site, Newly Released Irish State Papers Show

Shannon Airport Was Considered a NASA Space Shuttle Emergency Landing Site, Newly Released Irish State Papers Show

Declassified Irish State Papers show the U.S. asked Ireland in 1995 to designate Shannon Airport as an emergency landing site for NASA’s Space Shuttle. Documents detail an “eight to 20 second” window where the shuttle might not reach its main European abort site in Spain, making Shannon a backup. Irish officials outlined emergency plans but considered the odds of use low.

Comet 3I/ATLAS Latest Update: Wobbling Jets in a Rare Sun-Facing Tail, NASA’s Multi-Mission Watch, and What Happens Next

Comet 3I/ATLAS Latest Update: Wobbling Jets in a Rare Sun-Facing Tail, NASA’s Multi-Mission Watch, and What Happens Next

Comet 3I/ATLAS, only the third confirmed interstellar object, is leaving the solar system after reaching perihelion in October 2025. In late December, astronomers observed a rare anti-tail pointing toward the Sun and jets that wobble with a regular rhythm. The comet passed closest to Earth on December 19 at 1.8 AU. Scientists continue to analyze new data from its passage.

Comet 3I/ATLAS Today (Dec. 26, 2025): Wobbling Jets Detected in a Rare Sun-Facing Tail as the Interstellar Visitor Departs

Astronomers report Comet 3I/ATLAS shows wobbling jet structures inside a rare sun-facing anti-tail, with the jets’ angle shifting every 7.74 hours. The anti-tail extended up to 1 million kilometers. This marks the first periodic jet-angle modulation seen in an interstellar comet. On Dec. 26, 3I/ATLAS is magnitude 13.2, about 1.8 AU from Earth, in Leo.

Doomed SpaceX Starlink Satellite 35956 Photographed From Orbit After In‑Space Anomaly Spreads Debris

Doomed SpaceX Starlink Satellite 35956 Photographed From Orbit After In‑Space Anomaly Spreads Debris

A high-resolution orbital image captured Dec. 18 shows damaged Starlink satellite 35956 still largely intact after a Dec. 17 anomaly caused it to lose contact and begin an uncontrolled descent. SpaceX says the satellite and debris will burn up in the atmosphere within weeks and pose no risk to the ISS. Observers attribute the incident to an internal failure, not a collision.

Comet 3I/ATLAS Today (Dec. 23, 2025): New Spacecraft Data, X‑Rays, “Radio Signals,” and the Next Big Test at Jupiter

Comet 3I/ATLAS Today (Dec. 23, 2025): New Spacecraft Data, X‑Rays, “Radio Signals,” and the Next Big Test at Jupiter

Comet 3I/ATLAS, the third confirmed interstellar object, passed closest to Earth on Dec. 19 at 1.8 astronomical units, posing no threat. ESA and Japan’s XRISM mission detected an X-ray glow from the comet as its gases interacted with the solar wind, a first for an interstellar comet. NASA estimates its nucleus is between 440 meters and 5.6 kilometers wide. 3I/ATLAS was discovered by the ATLAS survey in Chile on July 1, 2025.

Interstellar Comet 3I/ATLAS Nears Closest Earth Flyby on Dec. 19: New X‑ray Views, UN Tracking, and What Scientists Know Now

Interstellar Comet 3I/ATLAS Nears Closest Earth Flyby on Dec. 19: New X‑ray Views, UN Tracking, and What Scientists Know Now

Interstellar comet 3I/ATLAS will make its closest approach to Earth on December 19, 2025, passing about 270 million kilometers away. The comet poses no threat, but global observatories are tracking it, aided by the International Asteroid Warning Network. New X-ray observations are revealing rare gases in the comet’s makeup. 3I/ATLAS is only the third confirmed interstellar object seen in our solar system.

NASA Loses Contact With Critical MAVEN Mars Orbiter: What the Sudden Silence Means for Future Missions

NASA Loses Contact With Critical MAVEN Mars Orbiter: What the Sudden Silence Means for Future Missions

NASA lost contact with the MAVEN Mars orbiter on December 6, 2025, after it slipped behind the planet during a routine orbit. The spacecraft, in service since 2014, has not responded to repeated attempts to re-establish communication. As of December 11, engineers are still investigating the cause and have not regained contact. MAVEN remains officially classed as lost-signal.
