Q&A with Jamie Bock, principal investigator of NASA’s SPHEREx mission (members only)

NASA’s Cassini orbiter sailed through the tenuous outermost reaches of Saturn’s atmosphere without trouble Monday, performing the first of five close swings nearer to the planet than any previous spacecraft before a final dive Sept. 15 to end the probe’s nearly 20-year mission.

The launch of NASA’s Perseverance Mars rover has been delayed two days to July 22 after an issue with ground support equipment at the Kennedy Space Center held up encapsulation of the spacecraft inside the payload fairing of its Atlas 5 rocket.

Cameras in various locations at Cape Canaveral and Kennedy Space Center capture the launch of a SpaceX Falcon 9 rocket carrying NASA’s TESS planet-hunting telescope.
