This March 2, 2015 NASA artist's concept obtained November 1, 2018 shows NASA's Dawn spacecraft arriving at the dwarf planet Ceres (lower right), travelling through space using a technology called ion propulsion, in which ions are accelerated out of an engine, giving the spacecraft thrust, the xenon ions glow with blue light. - Dawn, a NASA spacecraft that launched 11 years ago and studied two of the largest objects in the asteroid belt, has ended its mission after running out of fuel, officials said November 1, 2018. Scientists have known for about a month that Dawn was essentially out of its fuel, hydrazine, which kept the spacecraft's antennae oriented toward Earth and helped it turn its solar panels to the Sun to recharge. Then, the spacecraft missed scheduled communications with NASA's Deep Space Network on Wednesday and Thursday, and the space agency declared it formally dead.
