Live coverage: Mission control loses contact with Indian moon lander

Arianespace’s launch team loaded an Ariane 5 rocket full of super-cold liquid hydrogen and liquid oxygen propellants Tuesday for a fiery sunset blastoff from French Guiana at 2139 GMT (4:39 p.m. EST) with two European-built television broadcast satellites for Brazil and Indonesia.

Ten new satellites joined Iridium’s global voice and data relay constellation Sunday after a successful launch, and landing, of a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California. Liftoff occurred at 1:25 p.m. PDT (4:25 p.m. EDT; 2025 GMT).

NASA officials plan to replace the Mars 2020 rover’s heat shield after engineers discovered a crack in the structure earlier this month, but managers anticipate no delay in the mission’s scheduled launch date a little more than two years away.
