Live coverage: International Space Station crew lands in Kazakhstan

Two communications payloads — one for Intelsat and another for Europe’s data relay satellite system — lifted off from French Guiana aboard an Ariane 5 rocket at 1930 GMT (3:30 p.m. EDT) Tuesday.

Russian officials postponed the planned launch of a Proton rocket with an X-ray astronomy satellite Friday until no earlier than July 12 resolve a problem with an inadvertently drained battery on the vehicle.

Expanding a single instant in time to 30 minutes, the upcoming Atlas 5 rockets with Cygnus cargo-delivery freighters bound for the International Space Station will have an unprecedented opportunity available to launch each day.
