The future of NASA’s Dawn spacecraft, running low on hydrazine fuel and now flying around the dwarf planet Ceres without the help of internal pointing wheels, will be decided in the coming weeks by top space agency managers.

NASA’s InSight spacecraft plunged into the rarefied atmosphere of Mars at a speed of more than 12,000 mph Monday and braked to a gentle touchdown, setting the stage for a two-year surface mission to probe the planet’s deep interior.

NASA’s Kepler planet-searching spacecraft is stable and out of emergency mode, officials said Monday, and the observatory is downlinking data to help engineers determine what caused it to suspend science operations last week.
