After his twelve minutes outside, Leonov's space suit inflated in the vacuum to the point where he could not reenter the airlock. He opened a valve to allow some of the suit's pressure to bleed off, and was barely able to get back inside the capsule after suffering side effects of the bends. Because the spacecraft was so cramped, the crew could ...
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.
The other two crew members were exposed to the vacuum of space in the capsule, but did not leave it. First all-private crew spacewalk with commercially developed hardware, procedures, and the EVA suit. New record for most people exposed to the vacuum of space at a time.

When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [17] and a height of 121.3 m (398 ft). [6] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [18] it consists of the Super Heavy booster and the Starship upper stage [19] which are powered by Raptor and Raptor Vacuum engines.

A kinetic bombardment or a kinetic orbital strike is the hypothetical act of attacking a planetary surface with an inert kinetic projectile from orbit (orbital bombardment), where the destructive power comes from the kinetic energy of the projectile impacting at very high speeds.
Soon, the disk will grow so heavy that it will become violent and unwieldy, and inevitably, explode like a thermonuclear bomb. Neither star is destroyed however, and the process repeats itself ...
Salyut 1, the world's first space station, was deliberately de-orbited into the Pacific Ocean in 1971 following the Soyuz 11 accident. Its successor, Salyut 6, was de-orbited in a controlled manner as well. On June 4, 2000, the Compton Gamma Ray Observatory was deliberately de-orbited after one of its gyroscopes failed. The debris that did not ...
