Rosetta mission controllers have made the first call to “Go” for an attempted landing

The comet is currently hurtling through space at 24,600 miles per hour and its nucleus is only 2.5 miles wide. If the systems check out and a ‘Go-for-landing' is declared, the separation motors will fire at 3:46 a.m. ET Wednesday. But due to the distance between the spacecraft and Earth, it will take a further 18 minutes for the signal confirming separation to reach Earth.
