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.
The model landed by parachute undamaged and is in the collection of the Smithsonian National Air and Space Museum. The first proposed shock absorber was a ring-shaped airbag. It was soon realized that, should an explosion fail, the 1,100,000–2,200,000-pound (500,000–1,000,000 kg) pusher plate would tear away the airbag on the rebound.
GRB 080916C is a gamma-ray burst (GRB) that was recorded on September 16, 2008, in the Carina constellation and detected by NASA's Fermi Gamma-ray Space Telescope.The burst lasted for 23 minutes (1400 s).
Now new research claims to have shown that the explosion is in fact a nearly perfect sphere, and is completely symmetrical. Scientists have pursued a number of possible explanations – such as ...
The explosion, observed on March 7, was the second brightest gamma-ray burst ever witnessed by telescopes in more than 50 years of observations, over one million times brighter than the entire ...
What researchers are calling a "Once-in-a-lifetime event," is a nova, or explosion, between two suns 3,000 lightyears away. 'Once-in-a-lifetime event': Explosion in space to look like new star ...
Liquid lithium, serving as a moderator, fills the space between the D-T cylinder and the uranium sheath. Current is run through the liquid lithium, a Lorentz force is generated which then compresses the D-T plasma by a factor of 10 in what is known as a Z-pinch. The compressed plasma reaches criticality and undergoes fusion reactions.
The visual effects of a high-altitude or space-based explosion may last longer than atmospheric tests, sometimes in excess of 30 minutes. Heat from the Bluegill Triple Prime shot, at an altitude of 50 kilometers (31 miles), was felt by personnel on the ground at Johnston Atoll , and this test caused retina burns to two personnel at ground zero ...
