Incredible: Touchdown for the lander played out 510m kilometres - TopicsExpress



          

Incredible: Touchdown for the lander played out 510m kilometres from Earth, between the orbits of Mars and Jupiter, on a comet hurtling through space at more than 18km/s. At so vast a distance, even radio signals travelling at the speed of light take nearly half an hour to travel from Earth to the spacecraft, making real-time control of the landing impossible. Instead, the entire descent was precalculated, uploaded and run automatically. theguardian/science/2014/nov/12/rosetta-mission-philae-historic-landing-comet
