A peer-reviewed study from the German Aerospace Center reports that Mercury has lost up to 14 miles of diameter over its lifetime, roughly 30 percent more contraction than scientists previously measured. Researchers led by Gaku Nishiyama, a planetary scientist affiliated with Hokkaido University in Japan, compared maps of geologic faults and contraction features against surface roughness data built from NASA's Messenger spacecraft imagery . What they found was straightforward: the roughest patches of Mercury's battered surface showed far fewer of the wrinkle-like ridges that signal planetary shrinkage. The reason, the team concluded, is that billions of years of asteroid and comet impacts buried those ridges under debris, hiding the true…Open
Professor Kevin Knuth, whose peer-reviewed paper estimated the 2004 Nimitz Tic-Tac at up to 5,400 G, tells Ross Coulthart what conservation of energy says should have happened when it stopped. Watch this full episode of "Reality Check": https://youtu.be/UxiZrYBFjXk #TicTacUFO #Nimitz #UAP
David Burbach of the U.S. Naval War College joins “Jesse Weber Live” to describe how the US may engage with adversary nations beyond the atmosphere one day. “Think more like ‘Hunt for Red October’ than ‘Star Wars.’ Space war is going to be slow, like a chess game, satellites slowly sneaking up on each other — both sides trying to keep moves very secret, nobody quite sure what’s going on,” he said. #Space #Politics #War "Jesse Weber Live" brings a fresh, fast-paced, and often unexpected take on the day’s headlines, diving into the biggest stories through the lens of legal expertise.
On Tuesday’s "Hot Take," Jesse Weber breaks down the terrifying new reality of ‘orbital dogfighting’ and how the U.S. and China are preparing for a potential conflict in space. Joining the show is Peter Hays, adjunct professor at the Space Policy Institute at George Washington University, to discuss hunter satellites, secretive spaceplanes, and whether we are entering a brand new space arms race.
Researchers want to explore the idea that microscopic particles shed by alien civilizations have accumulated on the lunar surface, making it an archive of extraterrestrial technology.
A private spacecraft that was supposed to save NASA's sinking Swift Observatory has managed to come within nine miles of the doomed spacecraft and even snap pictures
