ALL THESE WORLDS ARE YOURS, EXCEPT EUROPA: NASA’s Juno space probe arrives at giant planet.

“Welcome to Jupiter!” flashed on screens at mission control at NASA’s Jet Propulsion Lab in Pasadena, California. The Juno team cheered and hugged.

“This is phenomenal,” said Geoff Yoder, acting administrator for NASA’s Science Mission Directorate.

The probe had to conduct a tricky maneuver to slow down enough to allow it to be pulled into orbit: It fired its main engine for 35 minutes, effectively hitting the brakes to slow the spacecraft by about 1,212 miles per hour (542 meters per second).

“NASA did it again,” said Scott Bolton, Juno principal investigator.

“We’re there, we’re in orbit. We conquered Jupiter.”
