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

The next time astronauts land on the moon, they will ride to the lunar surface in a spacecraft that looks a lot different than the Apollo-era landing module last used in 1972. Lander concepts proposed by SpaceX, Blue Origin and Dynetics — which won a combined $967 million in NASA funding Thursday — take wildly different approaches to carrying crews to the moon.

A day-and-a-half before its liftoff with a U.S. Air Force communications satellite, a United Launch Alliance Atlas 5 rocket rolled out to its launch pad at Cape Canaveral on Monday morning.

NASA’s Juno spacecraft sailed over Jupiter’s cloud tops early Monday, the fourth time the solar-powered probe has approached the giant planet and collected science data since its arrival last July 4.
