NASA has succeeded again as the spacecraft Juno finished its five-year journey to Jupiter on Monday. It successfully entered the planet’s orbit, according to USA Today.

The spacecraft had to be slowed down by over 1,200 mph in order to successfully be drawn in by Jupiter’s gravity — a delicate maneuver that many thought might fail. To complete this procedure, the craft fired its engines for approximately 35 minutes, which served to slow Juno down until it was effectively in orbit.

Scott Bolton is a scientist from California Institute of Technology’s Jet Propulsion Laboratory, which is in charge of Juno.

“NASA did it again,” he said in a news conference.

Juno is the first spacecraft to orbit the planet since the Galileo mission, which was terminated Sept. 21, 2003, according to CNN. The spacecraft is 540 million miles away from Earth and is the farthest solar-powered craft in our solar system, CNN reported.

The purpose of the mission is to discover more about the composition of the planet and the formation of our solar system. Because researchers think Jupiter was one of the first planets, it is likely that discoveries could tell us far more about how the solar system formed.

The plan is for Juno to orbit Jupiter 37 times for 20 months, diving in and out of the radiation belts of the planet.
