NASA has today had to place its new mission to the Moon on hold after high winds placed the rocket vehicle in danger.
The Gravity Recovery and Interior Laboratory (GRAIL) mission was set to depart at 12.37 GMT from NASA’s Cape Canaveral Air Force Base in Florida earlier today. Unfortunately, in a bold move by the space agency, the rocket’s launch was provisionally postponed at fear for the two probes inside.
GRAIL is a lunar bound mission being sent in order for scientists to map out the Moons gravitational surface in unprecedented detail. Two probes will be ejected from inside the Delta 2 rocket after exit from the Earth’s atmosphere and then team up together orbiting the rocky body as a synchronised couple. Both Probes, worth $258m each, will work collectively in an effort to cross section the moon from crust to core to help understand how all rocky planets and other celestial bodies are formed. A similar mission Gravity Recovery and Climate Change (GRACE) has already mapped Earths bumpy gravity field in attempts to understand why it forms in the way it does.
Man has always had a fascination with its earthly neighbour, unsurprisingly. The rocky form takes up the most space in our sky after the sun, its same face has stared down at us for millennia and its behaviour has always wanted to be tamed.
Michael Florent van Langren made the first map of the surface in 1645, thirty five years after the first telescopic observation was made by legendary astronomer Galileo Galilei. Over three hundred years later the first man-made object reached our orbiting partner, the Soviet Luna 2 module crashed into the surface in 1959.
Then came a defining moment in history when NASA led a team of astronauts to the exterior of the Moon to collect sample rocks and to mark it as the first celestial body, other than the Earth, to be graced by humans, in the entire Universe.
Another manned operation to the surface will be in a number of years but for now NASA has GRAIL.
Weather reports forecast that on September 9th 2011 the rocket holding the two probes will have a 40% chance of departure when its launch opportunity opens at 12.33 GMT. A second chance for takeoff will come at 13.12 GMT on the same day, if neither of these time zones present a successful mission outlook then the launch will be placed on hold once more.
NASA have until October 19th 2011 in this preliminary launch window until this mission will be placed on the literal back burner of a stand by launch pad.
