Live coverage: Antares rocket launch scrubbed in Virginia

China launched a civilian-operated Earth-observing satellite Tuesday to survey global land and water resources, air pollutants, greenhouse gases and other environmental parameters.

An automatic alarm in the final two minutes of the Delta 4-Heavy rocket’s countdown early Saturday forced officials to delay blastoff with NASA’s Parker Solar Probe by 24 hours.

Engineers working on the James Webb Space Telescope, which had its launch delayed to 2020 earlier this year, recently discovered another problem during testing at the observatory’s prime contractor Northrop Grumman in Southern California.
