Photos: Delta 2 rocket blasts off with SMAP satellite

At Cape Canaveral’s Vertical Integration Facility, adjacent to the Complex 41 launch pad, workers with United Launch Alliance stacked the Atlas 5 rocket that will propel NASA’s OSIRIS-REx spacecraft on its voyage to Asteroid Bennu.

The European-built Solar Orbiter spacecraft arrived in Florida late Friday after a trans-Atlantic journey from a test center in Germany, ready to begin preparations for a liftoff from Cape Canaveral in February aboard a United Launch Alliance Atlas 5 rocket.

United Launch Alliance chief executive Tory Bruno said Thursday the company will offer more rides for CubeSats aboard future Atlas 5 rocket flights, and give some away for free, in a bid to tap into a growing market of small satellites with applications in education, scientific research and commercial business.
