The Kessler syndrome is a scenario where space debris hits a satellite, creating fragments that destroy more satellites in a chain reaction until orbit is choked with junk. Losing GPS and communications could set civilization back to 1970.
In 2013, during a gameSuper Mario 64 speedrun, Mario suddenly teleported. A $1,000 bounty yielded no answers for 8 years. The cause: spaceradiation flipped a single bit in the console's memory, altering Mario's position coordinates.
About 80–90% of a rockets total weight is fuel. To send 1 kg of cargo to space, roughly 10 kg must be launched. Most of a rockets kinetic energy is carried away by the expelled gas, not the rocket itself.
The spaceelevator concept involves dropping a 36,000 km cable from an orbiting satellite down to Earth, rather than building a tower upward. If realized, it could reduce space cargo transport costs to between 1/100th and 1/10,000th of rocket launches.
SETI@home used volunteers' idle computers to scan space for extraterrestrial signals. Aimed at 50,000–100,000 machines, it drew 5.2 million participants and logged over 2 million years of computing—about 50x faster than the world's top supercomputer in 2013.
