- What scientists can learn from debris crashing into the moon
A four-ton upper stage of a SpaceX rocket hit the moon at 5,400 mph due to solar activity and gravity. The rocket was launched last year to carry lunar landers, and scientists are discussing concerns about lunar litter.
- SpaceX rocket debris believed to have crashed into the moon
NASA scientists believe a SpaceX Falcon 9 rocket debris crashed into the moon at over 5,000 mph, creating an explosion and debris field. The incident, attributed to solar activity and gravity, highlights growing concerns about space junk, with over 170 million tracked debris pieces orbiting Earth. Former NASA Administrator Sean O'Keefe emphasized the need for a global strategy to address uncontrolled orbital debris.
- Private mission to rescue NASA's aging telescope runs into its own trouble
Katalyst Space Technologies' Link satellite, intended to rescue NASA's Swift telescope, is experiencing thruster problems causing an uncontrollable spin. The mission aims to boost Swift's orbit to prevent its fall, with NASA providing $30 million in funding.
- NASA races to save Swift telescope from falling back to Earth with daring rescue mission
NASA is partnering with Katalyst Space Technologies to launch a robotic spacecraft named Lift to boost the Swift Observatory into a higher orbit, preventing it from re-entering Earth's atmosphere due to solar activity. The mission aims to extend Swift's operational life and could pave the way for future satellite rescues, including NASA's Hubble Space Telescope.
- Scientists discover towering red auroras reaching deep into space above Japan
Scientists discovered red auroras over Japan reaching unexpectedly high altitudes during mild space storms, suggesting solar activity may be stronger than previously understood. This finding has important implications for satellite safety and space weather prediction.
- Sun unleashes 2 colossal X-flares within 7 hours of each other, knocking out radio signals on Earth
The Sun emitted two powerful X-flares within 7 hours, causing temporary radio signal disruptions across Earth's dayside. The twin eruptions highlight increased solar activity and its immediate impact on communication systems.
