Engine trouble keeping Juno in elongated orbit until December

18 October 2016 Stephen Clark

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 this week to reshape the probe’s orbit around Jupiter.

Juno gets its closest look at Jupiter

28 August 2016 Stephen Clark

Nearly two months after NASA’s Juno spacecraft slipped into orbit around Jupiter, the solar-powered probe made a passage 4,200 kilometres over the giant planet’s colourful banded clouds Saturday, the closest planned encounter during its 20-month exploration of the solar system’s largest world.

Take a walk around NASA’s asteroid sample probe

26 August 2016 Stephen Clark

We take a walk around NASA’s OSIRIS-REx spacecraft before it was loaded into the nose cone of the Atlas 5 rocket that will launch it on 8 September.

One of NASA’s cleanest spacecraft ever is ready to fly

24 August 2016 Stephen Clark

Five years after winning $1 billion from NASA to mount the first U.S. asteroid sample return mission, scientists and engineers will get their last look at the OSIRIS-REx spacecraft this week as it is closed up inside the nose cone of an Atlas 5 rocket for launch in September.

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

6 July 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.

One last glimpse of Jupiter before Juno’s arrival

This is the final view taken by the JunoCam instrument on NASA’s Juno spacecraft before Juno’s instruments were powered down in preparation for orbit insertion.

Live coverage: NASA’s Juno spacecraft arrives at Jupiter

4 July 2016 Stephen Clark

NASA’s Juno spacecraft is barreling toward a rendezvous with Jupiter after a 2.8 billion kilometre (1.7-billion-mile), five-year trip from planet Earth. The research probe’s main engine will ignite for 35 minutes to maneuver Juno into orbit, and engineers expect to receive confirmation of burn’s start at 0318 GMT Tuesday.

NASA’s Juno mission is about to peel back the layers on Jupiter

4 July 2016 Stephen Clark

Whether you’re a casual stargazer or armed with a toolkit of observing gadgets, chances are you have caught a glimpse of Jupiter this year beckoning as one of the brightest objects in the night sky. It’s about to get its first visitor in nearly a decade, when NASA’s Juno spacecraft rockets into orbit.

Juno’s British-built engine ready for all-important firing at Jupiter

3 July 2016 Stephen Clark

Ground controllers have pressurised the Juno spacecraft’s propulsion system in preparation for a 5 July rocket firing by the probe’s UK-made rocket engine that will steer the spinning, solar-powered robot into orbit around Jupiter.

Jupiter and its satellites seen by ‘people’s camera’ on Juno probe

26 June 2016 Stephen Clark

The visible camera on NASA’s Juno spacecraft is capturing a time-lapse movie of Jupiter and its four largest moons as the orbiter dives toward the giant planet for a 4 July rendezvous, and officials have released a first taste of the views armchair scientists and space enthusiasts can anticipate over the coming weeks and months.
