NASA Dawn spacecraft runs out of fuel days after Kepler loss

Though the mission is over, Dawn's achievements remain. NASA elected to keep Dawn at Ceres and fly in different orbits around it, including its final orbit that brought the spacecraft to within 35 kilometers of the planet's surface. 1). It is expected to remain in orbit around Ceres for decades, but will no longer be able to communicate with Earth.

NASA's Kepler mission has come to an end

NASA's Kepler mission has come to an end

Now orbiting some 156 million kilometres from Earth, the spacecraft will drift further from our planet after its retirement, the USA space agency said. "It was like trying to detect a flea crawling across a auto headlight when the vehicle was 100 miles away", said Borucki said. When it comes to the planet quest, the next big thing on the horizon is the James Webb Space Telescope, which is now due for launch in 2021 and may be able to look for signs of life in the atmospheres of alien planets.
