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.

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.

Live coverage: Falcon 9 rocket counting down to launch tonight

14 August 2016 Stephen Clark

For the second time this year, SpaceX is preparing to launch a commercial communications satellite for Tokyo-based SKY Perfect JSAT Corp. early Sunday. A Falcon 9 rocket is set to blast off at 1:26 a.m. EDT (0526 GMT) from Cape Canaveral with the JCSAT 16 satellite to relay data and video across Japan and the Asia-Pacific. A first stage landing attempt will follow in the Atlantic Ocean a few minutes later.

China’s Yutu rover dies on the Moon

A Chinese rover sent to the Moon in 2013 has stopped operating, officials announced this week, ending a groundbreaking 31-month mission that made discoveries in lunar geology and catapulted China’s space programme to new heights.

ExoMars orbiter fine-tunes path toward red planet

29 July 2016 Stephen Clark

A European spacecraft cruising toward Mars fired its main engine, tweaking its trajectory and helping set up for carefully-choreographed simultaneous maneuvers to place part of the tandem mission into orbit around the red planet and deposit a stationary battery-powered lander on the Martian surface.

Japan’s Hitomi observatory made cosmic discovery before failing

12 July 2016 Stephen Clark

Japan’s doomed Hitomi observatory peeled back a veil on the inner workings of the Perseus cluster of galaxies before the satellite spun out of control earlier this year, revealing in unprecedented detail how gas heated to millions of degrees behaves around an unseen supermassive black hole, scientists said.

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.

Juno spacecraft braves the unknown at Jupiter to enter orbit

5 July 2016 Stephen Clark

Setting up post at the king of planets, NASA’s Juno spacecraft fired its main engine for 35 minutes Monday, steering into orbit around Jupiter to peer inside the gas giant and give scientists a better idea of how the solar system took shape 4.6 billion years ago.

Scientists on edge awaiting Juno’s perilous encounter with Jupiter

4 July 2016 Stephen Clark

Speeding toward Jupiter at nearly 40 miles per second, NASA’s Juno spacecraft must brave a field of computer-zapping radiation and Jupiter’s tenuous ring of ice and dust particles when it brakes into orbit around the planet Monday and zooms just 2,900 miles from the world’s turbulent cloud tops.
