Its blades will spin at almost 3,000 rpm, roughly 10 times the rate employed by helicopters on Earth.NASA pushes back giant space telescope launch to 2020 The altitude record for a helicopter air force homme flyin black sambas g here on Earth adidas marathon tr original is about 40,000 feet. The atmosphere of Mars is only one per cent that of Earth, so when our helicopter is on the Martian surface, it s already at the Earth equivalent of 100,000 feet (30,480 meters) up, Mimi Aung, the Mars Helicopter project manager at NASA s Jet Propulsion Laboratory, said in a statement.NASA officials said the rotorcraft will Hsyk Vehicle number plate fee jacked up
