Engineers have leveled the seismometer and made progress on adjusting the position of the tether so that it doesn't interfere for the experiment. Most significantly for the mission, they have balanced the Very Broad Band sensors -- 3 of SEIS’ 6 seismic sensors -- and confirmed that they are generating good data.
New Horizons has "phoned home" as expected, 4 hours after its closest approach to 2014 MU69. Its brief transmission contained no science data, but gave the scientists welcome news: New Horizons has successfully pulled off the most distant flyby ever.
Today at 19:43 UTC, OSIRIS-REx entered orbit at asteroid Bennu. In so doing, it accomplished both the tightest orbit (at an altitude under 2 kilometers) and the orbit of the smallest object ever. UPDATE: Early science results from OSIRIS-REx discussed at New Horizons MU69 flyby event.
Unaffected by the shutdown of the U.S. government, New Horizons is still on course for its New Year’s encounter with 2014 MU69 (nicknamed “Ultima Thule”). This post collects the latest images from New Horizons' approach to the tiny Kuiper belt object and will be updated regularly.
After more than 11 years in deep space, after unveiling the two largest uncharted worlds in the inner solar system, after overcoming myriad daunting obstacles, Dawn's interplanetary adventure has come to an end.
It’s been a busy first three weeks on the InSight mission, and they’ve already achieved a major milestone: placing the seismometer on the ground. They've also gathered a self-portrait and 360-degree panorama.
New Horizons is rapidly approaching its New Year’s encounter with the most distant world ever visited, 2014 MU69. Closest approach will be at a distance of 3,500 kilometers at about 05:33 on 1 January UTC.
Mars Reconnaissance Orbiter has finally spotted the InSight lander, its parachute, and its heat shield resting on the Martian surface. The images confirm the location of InSight's landing site, a little to the north and west of the center of the landing ellipse. The lander is located at 4.499897° N, 135.616000° E.
Just after a failed drill attempt at Inverness, Curiosity suffered a serious computer problem. The mission has now recovered by switching computers, and has successfully drilled at Highfield. One last drill site in "red Jura" rocks is planned before leaving Vera Rubin ridge behind.
Voyager 2 is now outside the reach of the solar wind, traveling in the interstellar medium. Unlike Voyager 1, Voyager 2 has a working plasma spectrometer so will be doing exciting new science. It is expected to last another 5 to 10 years, though not with all instruments operating.
