The two satellites involved in the collision: Iridium 33 (silver and gold) and a digital rendering of Kosmos 2251 (blue cylinder) 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 ...
Saudi officials inspect a crashed PAM-D module in January 2001. Space debris usually burns up in the atmosphere, but larger debris objects can reach the ground intact. According to NASA, an average of one cataloged piece of debris has fallen back to Earth each day for the past 50 years.
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.
Gold's value is based on faith –- like the faith you have in the U.S. dollar -- and there are many vested interests who want gold to retain its value the way it has for thousands of years.
Investors have been burned by past crashes, most notably in the early 1980s, when gold prices fell some 45% as the Federal Reserve hiked interest rates to stop runaway inflation; and in 2013, when ...
The crash landing sites themselves are of interest to space archeology. Luna 1 , not itself a lunar orbiter, was the first spacecraft designed as an impactor . It failed to hit the Moon in 1959, however, thus inadvertently becoming the first man-made object to leave geocentric orbit and enter a heliocentric orbit , where it remains.
A cat named Creme Puff is considered to be the oldest cat ever with a lifespan of 38 years and 3 days. We’ve compiled a list of the 10 oldest cats by accepting the owner’s word as reported in ...
April 10: During descent to Earth of Soyuz MS-02 crewed spacecraft, a part of the parachute system hit the capsule during deployment, causing partial depressurization at the altitude of about 8 kilometres (5.0 mi), 3 kilometres (1.9 mi) higher than during normal operations. As the crew were wearing pressure suits, the loss of pressure didn't ...
