Q&A with Carol Raymond, deputy principal investigator on NASA’s Dawn mission

Look back on Monday’s blastoff of a SpaceX Falcon 9 rocket from the Kennedy Space Center in this gallery of photos captured by remote cameras at the launch pad, plus views of the first stage returning to Cape Canaveral for a propulsive landing.

A European Ariane 5 rocket took off from French Guiana and delivered two commercial communications satellites and a NASA scientific package to orbit Thursday after an unexpected radio blackout raised worries that the mission failed. But questions lingered early Friday about the accuracy of the payload deployments.

A technical issue with the United Launch Alliance Atlas 5 rocket that will send NASA’s $2.4 billion Perseverance rover toward Mars has pushed the mission’s launch date back to no earlier than July 30, nearly two weeks into a month-long window for the rover to head to the Red Planet, or else face a two-year delay.
