Photos: Atlas 5 rolls out for launch

A flight demonstration of an inflatable heat shield that could be used to retrieve reusable engines from United Launch Alliance’s next-generation Vulcan rocket, and for the delivery of heavier cargo to the surface of Mars, is planned for launch in late 2021 or early 2022 as a piggyback payload on an Atlas 5 rocket with a NOAA weather satellite.

United Launch Alliance’s final Delta 2 rocket is now on display at the Kennedy Space Center Visitor Complex in Florida, a monument to an industry workhorse that helped build the GPS navigation satellite fleet and enabled a new era of Mars exploration.

A decade in the making, the core stage for NASA’s first Space Launch System heavy-lift rocket rolled into the Vehicle Assembly Building at the Kennedy Space Center Thursday to join up with twin solid rocket boosters and an Orion capsule for an unpiloted test flight around the moon.
