New Horizons Spacecraft Returns Its Sharpest Views of Ultima Thule

The most detailed images of Ultima Thule -- obtained just minutes before the spacecraft's closest approach at 12:33 a.m. EST on Jan. 1 -- have a resolution of about 110 feet (33 meters) per pixel. Their combination of higher spatial resolution and a favorable viewing geometry offer an unprecedented opportunity to investigate the surface of Ultima Thule, believed to be the most primitive object ever encountered by a spacecraft. ...

Opportunity did not answer NASA’s final call, and it’s now gone to us

Late Tuesday night, scientists at NASA's Jet Propulsion Laboratory sent their final data uplink to the Opportunity rover on Mars. Over this connection, via the Deep Space Network, the American jazz singer Billie Holiday crooned "I'll Be Seeing You".

But in the end, no response came. Opportunity would finally be declared dead on Sol 5352, as in five thousand, three hundred, and fifty-two days on Mars. ... Sehen Sie mehr

First green leaf on moon dies as temperatures plummet

The appearance of a single green leaf hinted at a future in which astronauts would grow their own food in space, potentially setting up residence at outposts on the moon or other planets. Now, barely after it had sprouted, the cotton plant onboard China’s lunar rover has died.

The plant relied on sunlight at the moon’s surface, but as night arrived at the lunar far side and temperatures plunged as low as -170C, its short life came to an end. ... Sehen Sie mehr
