Running a day late, a United Launch Alliance heavy-lift Delta 4 rocket thundered away from Cape Canaveral early Sunday, boosting NASA’s $1.5 billion Parker Solar Probe into space on a daring seven-year mission to “touch the sun” with repeated trips through the star’s blazing outer atmosphere.

Astrobotic, a Pittsburgh-based company developing a robotic lunar lander, will launch its first moon mission under contract to NASA on the debut flight of United Launch Alliance’s Vulcan Centaur rocket in 2021, officials announced Monday.

NASA’s Parker Solar Probe, fueled and buttoned up for liftoff Aug. 11 on the first mission to fly through the sun’s corona, arrived at its launch pad at Cape Canaveral early Tuesday after a convoy trip from a nearby fueling and test facility.
