    The Beresheet moon lander will attempt to become the first privately-funded spacecraft to reach the moon, and these photos show the robotic probe’s journey through testing inside a clean room at Israel Aerospace Industries, followed by its attachment to a multi-satellite stack for launch on a Falcon 9 rocket. Beresheet, which means “genesis” or “in…

    Scientists’ understanding of the shape of Ultima Thule, officially known as 2014 MU69, has changed since the New Horizons spacecraft’s Jan. 1 flyby. Imagery downlinked by the probe in recent weeks suggests Ultima Thule’s two lobes have a flatter shape than the spherical projection suggested by the flyby’s initial pictures. The dashed blue line marks…

    MarCO-B, one of the experimental Mars Cube One (MarCO) CubeSats, took these images as it approached Mars. Credit: NASA/JPL-Caltech After a successful mission that pushed the limits of small satellite technology, ground controllers have lost contact with two briefcase-sized CubeSats beyond Mars, NASA said Tuesday. The pioneering Mars Cube One, or MarCO, mission set records…
