At 5:31 PM Phoenix time, we are 5 Hours away from the landing of Curiosity in Gale Crater on Mars, pictured above. The signal from Curiosity to the orbiting spacecraft Mars Odyssey to Earth takes about 14 minutes. In the view from Mars, the Earth sets while Curiosity is still suspended from the parachute. Communication is only through the orbiting satellite.
So we won’t know until long after the landing is over.
Meanwhile, get your peanuts ready.
