Space junk from old SpaceX missions may have landed in rural Australia. A piece of charred material reportedly left over from the reentry of the SpaceX spacecraft was found in the middle of a sheep paddock near Dalgety; The discovery followed an “explosion” heard by witnesses July 9 local time in the southeast of the country. SpaceX has yet to confirm whether the pieces were part of its Crew-1 Dragon spacecraft that managed to crash on May 2, 2021. That said, longtime space debris tracker Jonathan McDowell said in twitter (opens in a new tab) Friday (July 29) that Dalgety was actually under the re-entry projection of a piece of unstressed Dragon “stem”, dumped before re-entry. McDowell added that the photos showed that the debris came from one of the trunk fins. These fins are on the circumference of the rocket to aid aerodynamics during the launch phase of the mission.

Credit: NASA/Goddard Space Flight Center/Arizona State University NASA’s Lunar Reconnaissance orbiter (LRO) has discovered a crater hole near the Moon’s Sea of ​​Tranquility at room temperature. An LRO onboard thermal imager found that a 328-foot depression about the length and width of a football field had overshadowed an area that maintained a constant, cool temperature of around 63 degrees Fahrenheit. The hope is that future astronauts will be able to use such a hole as a shelter from the extreme temperatures of the lunar surface that can fluctuate between 260 degrees Fahrenheit on lunar days and cold to minus 280 degrees Fahrenheit on lunar nights. First discovered on the Moon in 2009, such holes, subsurface lava tunnels, and caves can also offer protection from cosmic rays, solar radiation, and micrometeorites, NASA said. “Abou

Mars explorers may have to dig deeper for signs of ancient life. New research shows that certain protein-building amino acids that could be evidence of ancient life on Earth Mars more susceptible to radiation than scientists thought, meaning any amino acids left behind by life forms might only survive if they were buried deep beneath the planet’s surface. “Our results show that amino acids are destroyed by cosmic rays in Martian surface rock and regolith at a much faster rate than previously thought,” Alexander Pavlov, a space scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said in a statement. statement . “Current Mars rover missions are drilling to about two inches (about five centimeters). At that depth, it would take only 20 million years to completely destroy the amino acids.” Related: Possible sign of Martian life?
