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.
