Live coverage: ExoMars orbiter safely arrives at Mars, lander’s fate uncertain

NASA’s New Horizons spacecraft made a historic New Year’s encounter with an object nicknamed Ultima Thule in the Kuiper Belt a billion miles beyond Pluto. The probe passed around 3,500 kilometres from the mysterious object at 0533 GMT on New Year’s Day, making it the most distant Solar System body ever explored up close.

Making its fifth science pass close to Jupiter’s turbulent cloud tops, NASA’s Juno spacecraft sailed by the Solar System’s king planet Friday to collect another treasure trove of data on the giant world’s atmosphere, internal structure, and magnetic field.

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.
