Juno orbiter races by Jupiter on fourth science pass

March 27, 2017 Stephen Clark

NASA’s Juno spacecraft sailed over Jupiter’s cloud tops early Monday, the fourth time the solar-powered probe has approached the giant planet and collected science data since its arrival last July 4.

NASA’s Juno spacecraft to remain in current orbit around Jupiter

February 21, 2017 Stephen Clark

Concerns about the health of the Juno spacecraft’s main engine have compelled NASA managers to keep the research probe in its current arcing, high-altitude orbit around Jupiter, a decision that will delay the full science return from the $1.1 billion mission but should still allow it to meet all predetermined objectives.

Juno dives over Jupiter’s cloud tops with main engine still offline

NASA’s Juno spacecraft made a high-speed pass less than 3,000 miles over Jupiter’s turbulent clouds Thursday, taking dozens of pictures, measuring radiation and plasma waves, and peering deep inside the planet’s atmosphere, but officials still have not cleared the orbiter’s main engine for a planned maneuver to position the probe in its intended science orbit.

Intelsat satellite in service after overcoming engine trouble

An Intelsat communications satellite launched last August entered service Sunday, about three months later than planned after a main engine problem forced engineers to position the craft in geostationary orbit using backup low-thrust rocket jets.

Juno recovers from reboot, but propulsion problem lingers

October 28, 2016 Stephen Clark

NASA’s Juno spacecraft will stay in its current long-period orbit around Jupiter until at least February, and perhaps longer, as engineers study balky valves inside the science probe’s propulsion system and an unexpected computer reboot that interrupted key functions of the orbiter earlier this month.

Mission managers keeping Juno in elongated orbit until December

Ground teams are buying more time to study two sluggish valves inside the Juno spacecraft’s fuel pressurization system and postponing a major engine burn that was scheduled for next week to reshape the probe’s orbit around Jupiter, officials said Friday.

Juno beams back dramatic new pictures of Jupiter

September 2, 2016 William Harwood

NASA’s Juno spacecraft, making its first scientific run over Jupiter’s poles Aug. 27, captured remarkable images of Jupiter’s atmosphere, showing that the equatorial bands and zones familiar to even amateur astronomers completely disappear at high latitudes.

Juno gets its closest look at Jupiter

August 27, 2016 Stephen Clark

Nearly two months after NASA’s Juno spacecraft slipped into orbit around Jupiter, the solar-powered probe made a passage 2,600 miles over the giant planet’s colorful banded clouds Saturday, the closest planned encounter during its 20-month exploration of the solar system’s largest world.

Researchers eager for Juno’s first chance for Jupiter science

July 15, 2016 Stephen Clark

NASA’s Juno spacecraft fine-tuned its orbit around Jupiter this week, helping steer the spinning space probe on a course to dip beneath the giant planet’s radiation belts in late August for the first time with all its science instruments activated.

See Jupiter’s Galilean moons in motion from Juno’s camera

July 5, 2016 Stephen Clark

Juno’s visible camera had a bird’s-eye view of Jupiter’s four largest moons over the last few weeks, recording the satellites in their orbital ballet around the giant planet as the spacecraft approached from above Jupiter’s north pole.
