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.

Rosetta mission ends with comet touchdown

30 September 2016 Stephen Clark

Europe’s Rosetta mission ended its 12-year mission Friday with a slow-speed belly-flop on comet 67P/Churyumov-Gerasimenko, concluding an interplanetary odyssey that gave humanity a first close-up introduction to a class of objects which has stimulated imaginations for millennia.

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.
