Watch a video replay of NASA’s exoplanet announcement

Iridium has secured a launch for five more of its next-generation communications craft in a rideshare arrangement with two U.S.-German research satellites aboard a SpaceX Falcon 9 rocket by early 2018.

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.

NASA’s Perseverance rover has been closed up inside its protective aeroshell, the structure that will protect the spacecraft when it plunges into the Martian atmosphere, in preparation for launch no earlier than July 20 from Cape Canaveral.
