Live coverage: SpaceX Falcon Heavy launches NASA’s Psyche on mission to a metal asteroid

Juno left the Earth atop a United Launch Alliance Atlas 5 rocket on Aug. 5, 2011, beginning its journey to Jupiter atop the most powerful Atlas variant with five side-mounted boosters. It arrives at the gas giant on Monday.

Nearly a decade after Orbcomm raised the money to pay for a second-generation satellite fleet to drastically expand the company’s reach, the $230 million program is finally primed for completion after Monday’s launch of a Falcon 9 rocket from Cape Canaveral.

Science teams from across the United States have submitted 28 proposals for missions to explore the moons of Jupiter and Saturn, touch the asteroid-like satellites orbiting Mars, visit unseen worlds and hunt for objects that could strike Earth one day.
