NASA's Juno spacecraft has successfully entered Jupiter's orbit after traveling 2.8 billion kilometers over five years.
The spacecraft, moving at 193,121 kilometers an hour, was successfully slowed to 1,931 kilometers an hour and captured by Jupiter's gravity on Monday (U.S. time).
"It's a very significant event," said Juno project manager Rick Nybakken. "This is make-or-break. It's all or nothing."
The engineer posted on Twitter that the rocket burn to reduce speed was accurate to within a second of the flight plan.
Juno is expected to orbit Jupiter 37 times over 20 months.
It will then drop into the planet's atmosphere, where it will burn up to prevent any damage to Europa, one of Jupiter's moons that NASA considers a major candidate to harbor life.
