Q&A with Scott Bolton, principal investigator on NASA’s Juno mission

The MASCOT lander released from Japan’s Hayabusa 2 spacecraft this week made three hops to different locations on asteroid Ryugu before draining its battery, outliving its design life and sending back data from all four of its instruments, according to German and French officials who developed the surface robot.

NASA’s robotic Dawn spacecraft is now getting its closest look at the dwarf planet Ceres, the largest resident of the asteroid belt, and mission managers say the probe has enough leftover propellant to keep flying into early 2017, several months beyond the prescribed end of its survey.

A European Ariane 5 rocket is scheduled for blastoff  Tuesday from a jungle launch pad in South America with two geostationary telecom payloads — one owned by a Saudi Arabian operator and built in Colorado by Lockheed Martin, and another for India’s space agency.
