Live coverage: Soyuz crew lands in Kazakhstan

Watch as the New Horizons team hold a press conference an hour after they received confirmation that the spacecraft had successfully flown by Ultima Thule and had recorded the expected amount of science data.

Russian and European teams at the Guiana Space Center in South America plan to detach a UAE spy satellite from its Soyuz launcher to replace the rocket’s Fregat upper stage, forcing a likely delay until April from the mission’s original launch date of Friday.

SpaceX launched its 12th Falcon 9 rocket of the year Thursday from California with Taiwan’s Formosat 5 Earth observation satellite. The two-stage rocket lifted off at 11:51 a.m. PDT (2:51 p.m. EDT; 1851 GMT) and deployed the Taiwanese-built spacecraft into polar orbit. The Falcon 9’s first stage booster successfully landed on a drone ship downrange in the Pacific Ocean.
