Deep Impact at Comet 9P/Tempel 1 Dart Impact at Dimorphos Mars 2020 Skycrane descend stage crash smoke plume in the distance. This is a list of uncrewed spacecraft which have been intentionally destroyed at their objects of study, typically by hard landings or crash landings at the end of their respective missions and/or functionality.
Very-high-energy gamma rays may be slowed down as they propagate through the quantum turbulence of space-time. [6] [7] The explosion took place 12.2 billion light-years (light travel distance) away. That means it occurred 12.2 billion years ago—when the universe was only about 1.5 billion years old.
Just seconds after Elon Musk’s SpaceX launched the first test flight of its biggest and most powerful rocket yet, the craft started tumbling uncontrollably and exploded, leaving a dramatic cloud ...
GRB 221009A was an extraordinarily bright and very energetic gamma-ray burst (GRB) jointly discovered by the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope on October 9, 2022. The gamma-ray burst was ten minutes long, [1] but was detectable for more than ten hours following initial detection.
Astronomers are anticipating the appearance of a “new star” triggered by an explosive event that could appear in the night sky anytime between now and September. ‘Once-in-a-lifetime ...
International Space Station astronaut Alexander Gerst caught footage of the Cygnus spacecraft as it burned up in Earth's atmosphere and broke apart. The resupply ship was carrying 1.4 tons of food ...
NASA artist rendering, from 1999, of the Project Orion pulsed nuclear fission spacecraft. Project Orion was a study conducted in the 1950s and 1960s by the United States Air Force, DARPA, [1] and NASA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft.
The episode Conflict from Gerry and Sylvia Anderson's U.F.O. sci-fi TV series shows how small alien spaceships could use Terrestrial space debris such as orbital boosters to become undetectable by SHADO's orbital Space Intruder Detector (S.I.D.).
