NASA Will Explore F-1 Upgrade For Heavy LifterThe powerful rocket engine developed in the 1960s to launch the first men to the Moon could be reprised in the 2020s as the powerplant for strap-on boosters that NASA hopes to use in heavy-lift human missions to Mars. Under a new NASA risk-reduction project, Dynetics Inc., a relative newcomer to space launch, will explore the idea for the U.S. agency in partnership with Pratt & Whitney Rocketdyne.
Rocketdyne built the 1.5-million-lb.-thrust F-1 engine for NASA, which mounted five of the kerosene-fueled behemoths in the Saturn V first stage to propel the massive Saturn/Apollo stack off the launch pad. The F-1—19 ft. tall, with a nozzle 12.5 ft. across—epitomized the scale of the flight hardware and ground infrastructure NASA used to beat the Soviet Union to the Moon. If NASA decides to fly it again, it probably will be tested in the same stands built for the F-1 at the agency's Marshall and Stennis field centers, stacked in the same 40-story Vehicle Assembly Building at the Kennedy Space Center used for Apollo and the space shuttle, and launched from one of the pads built for the Moon program.
Dynetics scored big in a $200 million NASA effort to reduce the risk on advanced boosters for the planned Space Launch System (SLS) that Congress ordered as a government-owned deep-space alternative to the commercial vehicles the agency wants to use for transport to the International Space Station. Last week NASA selected the company to negotiate for three of six 30-month study contracts designed to reduce risk on the twin boosters that will be needed to raise the SLS capability from an initial 70 metric tons to the 130 metric tons the agency believes will be needed for human missions beyond low Earth orbit.
