The deep space Planck telescope will retire this week after a successful four-year mission that revealed our universe to be 80 million years older than previously thought, the
Mission controllers fired Planck's thrusters to empty its fuel tanks - one of the final steps before the spent satellite can be "parked" in a safe orbit around the Sun, far away from the Earth and Moon, after it went out of action yesterday.
"The final step will be switching off the transmitters: we will witness the silencing of Planck and we will never receive a signal from her again," ESA spacecraft operations manager
"This is important because we cannot cause radio interference for any future mission."
Launched in 2009, Planck was to look at radiation remnants from the "Big Bang" that created the universe some 14 billion years ago.
In March, ESA unveiled a 50-million pixel, all-sky snapshot of radiation left over from the Big Bang, compiled from data gathered by the orbiter. - Sapa-AFP
