Strictly speaking, a satellite collision is when two satellites collide while in orbit around a third, much larger body, such as a planet or moon. This definition is typically loosely extended to include collisions between sub-orbital or escape-velocity objects with an object in orbit.

Space collisions happen when stars, asteroids and even galaxies smash into one another. Learn what space collisions look like and what the results are.

2024年10月11日 · In this activity, students make predictions about what will happen when two objects collide and compare their hypotheses to their observations. They also compare what happens when objects made of different materials collide to determine how the makeup of objects affects the impact.

2024年11月22日 · Using one of the most powerful telescopes on Earth, astronomers have witnessed an intimidating 2-million-mile-per-hour (3.2-million-kilometer-per-hour) smash-up between galaxies at a...

On February 10, 2009, two communications satellites —the active commercial Iridium 33 and the derelict Russian military Kosmos 2251 —accidentally collided at a speed of 11.7 km/s (26,000 mph) and an altitude of 789 kilometres (490 mi) above the Taymyr Peninsula in Siberia. [1][2][3][4][5][6] It was the first time a hypervelocity collision occurr...

Space Shuttle Challenger breaks up during its 1986 launch resulting in the death of all seven crew members. This article lists verifiable spaceflight-related accidents and incidents resulting in human death or serious injury.

2009年2月11日 · WASHINGTON — Iridium Satellite LLC confirmed today that one of its satellites was destroyed Feb. 10 in an unprecedented collision with a spent Russian satellite and that the incident could...

If so many satellites are sent to space, how do they not end up colliding? Source: Celes Trak. A standard collision avoidance procedure has been established by space agencies to avoid any such accident. Every time a satellite is launched, a Collision On …

2021年8月17日 · In March, the U.S. Space Force's 18th Space Control Squadron (18SPCS) reported the breakup of Yunhai 1-02, a Chinese military satellite that launched in September 2019. It was unclear at the...

1993年5月25日 · NASA's Hubble Space Telescope (HST) has discovered a new population of exceptionally bright and young star clusters at the heart of a head-on collision between two galaxies. The orbiting telescope also discovered a rotating, pinwheel-shaped disk at …
