QUOTE Late afternoon on Tuesday, June 5, 2007, MESSENGER will fly within about 210 miles (340 kilometers) of the surface of the planet Venus, and get a gravity kick toward its ultimate destination, the sun-baked planet Mercury... Mission operators at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., said MESSENGER’s systems performed flawlessly as the spacecraft sped over the cloud tops of Venus at a relative velocity of more than 30,000 miles per hour, passing within 200 miles of the surface of the planet at 23:08 UTC (7:08 p.m. EDT). 200 miles? Was this an areobraking event? |
