NASA’s Dawn spacecraft will remain at Ceres for the rest of its mission, heading closer to the asteroid belt’s largest resident than ever before to obtain new measurements of ice, salts and a tenuous intermittent atmosphere detected around the dwarf planet, the space agency announced Thursday.

In the ten years since its launch from Cape Canaveral, NASA’s Dawn spacecraft has orbited the two largest worlds in the asteroid belt and overcome defective components that threatened to derail the mission on its 4 billion-mile voyage, discovering unexpectedly rich geologic tapestries suggesting both destinations have a watery past.

A very close encounter

Back in October 2012, the near-Earth asteroid 2012 TC4 had a close encounter with Earth. It passed our planet at a distance only a quarter of that between the Earth and the Moon. In October 2017, this small asteroid, with a size of only about 15 to 30 metres, will return for another very close fly-by, making it the perfect object to test the asteroid detection and tracking network.

Earlier launch of NASA’s Psyche mission touted as cost-saving measure

A NASA spacecraft set to explore a metallic asteroid for the first time will launch in 2022, a year earlier than originally planned, and reach its destination in 2026, four years ahead of schedule, giving ground teams a shorter wait for the mission’s scientific payoff and shaving $100 million off the project’s total cost, officials said Wednesday.
