JUNO POSITION & STATUS

View of Juno's position on January 10 from NASA's Eyes on the Solar System.

As of Jan. 10, Juno was approximately 78 million miles (125 million kilometers) from Earth. The one-way radio signal travel time between Earth and Juno is currently about seven minutes. Juno is currently traveling at a velocity of about 17 miles (28 kilometers) per second relative to the sun. Velocity relative to Earth is about 16 miles (26 kilometers) per second. Juno has now traveled 1.16 billion miles (1.87 billion kilometers, or 12.5 AU) since launch.

The Juno spacecraft is in excellent health and is operating nominally.

Recent Spacecraft Significant Events

The Juno operations team successfully enabled the solar array medium strings (for the second and final time) on Jan. 7. This action increases available power, adding three medium string panels to the two long string panels, as the spacecraft moves farther outward from the sun and into the asteroid belt. The next (and final) string enable will be to bring the six short-string panels online around Sept. 2014. With that action, the full power production capability of Juno’s huge solar arrays – the first to power a mission to Jupiter – will be enabled.
