Photos: Atlas 5 rocket soars from West Coast

United Launch Alliance has completed stacking of the major elements of the Atlas 5 rocket assigned to power NASA’s Perseverance rover toward Mars, but the mission’s launch date has been pushed back three days to July 20 after teams repaired an issue with a crane in the Atlas 5’s assembly building.

The United Launch Alliance Atlas 5 rocket lifted off from California at 10:30 a.m. local time (1:30 p.m. EST; 1830 GMT) today to deliver the sharp-eyed WorldView 4 satellite into space to collect best-in-the-industry, 31-centimeter-resolution commercial imagery for retail.

An Atlas 5 rocket successfully launched another Cygnus cargo freighter for Orbital ATK Tuesday night, fulfilling the booster’s role of reestablishing America’s resupply link to the International Space Station.
