Juno Post-Arrival News Conference

The OSIRIS-REx sample-return spacecraft is finding one surprise after another orbiting asteroid Bennu, including unexpected “ejection events.”

Before sunrise on Thursday 19 January, observers in Western Europe can see an interesting celestial conjunction in the southern sky. At about 6am local time, the waning gibbous Moon, largest planet Jupiter and Spica — the brightest star in the constellation of Virgo — all lie in a line encompassed by the field of view of a typical 7x or 8x binocular.

Despite ongoing problems with its flash memory, Opportunity reached the summit of “Cape Tribulation” on the rim of Endeavour Crater during its 3,894th Martian day, pausing to photograph the stunning vista.
