SpaceX Completes Crewed Orbit and Entry Review

NASA Commercial Crew Program (CCP) partner Space Exploration Technologies (SpaceX) recently reviewed the systems critical to sustaining crews in orbit and returning them safely to Earth aboard the company's Dragon spacecraft.

SpaceX is one of three commercial space companies working under NASA's Commercial Crew Integrated Capability (CCiCap) initiative to develop spaceflight capabilities that eventually could provide launch services to transport NASA astronauts to the International Space Station from U.S. soil.

During the preliminary design review at SpaceX headquarters in Hawthorne, Calif., company engineers presented NASA representatives and aerospace industry experts detailed analyses of Dragon systems critical to keeping crews safe in orbit and during re-entry operations. From basic life support functions, including pressurizing Dragon with breathable air, to stocking the capsule with enough food and water for as many as seven crew members, the spacecraft must be designed to protect humans in the harsh conditions of space. Company designers and NASA engineers dissected the plans carefully to make sure no details were overlooked.

"NASA has learned a lot about keeping our astronaut crews safe throughout a mission, and we don't want those lessons to be forgotten," said Ed Mango, NASA's CCP manager. "So, we're sharing a lot of what we already know, and the company is adding its own innovations to suit its needs and meet its challenges."

The review detailed equipment and software aboard Dragon that would help guide crews to the International Space Station for rendezvous and docking operations. This included discussion on SpaceX’s planning for software code which, in this modern era of spaceship design, just as critical as the hardware design. The company also described how the spacecraft will be operated both by its onboard crew and by ground controllers.

While SpaceX works to further develop its crewed Dragon spacecraft, it also is preparing for the upcoming launch of the third of at least 12 cargo missions to the space station with a remotely controlled Dragon under NASA's Commercial Resupply Services contract.

"SpaceX’s Dragon spacecraft was designed from the outset to accommodate the upgrades necessary to safely carry people, so we’re excited to have reached the halfway point in our agreement with NASA to design those features,” said Gwynne Shotwell, SpaceX president and chief operating officer. “As we leverage our experience successfully delivering cargo both to the International Space Station and back to Earth, SpaceX remains committed to providing the safest manned flights ever conducted."

In December, the company completed preliminary design reviews covering the ground systems and ascent, which are the first two phases of flight. Completion of the orbit and entry review clears the way for SpaceX to proceed with detailed designs for its integrated space transportation system, comprised of its Dragon spacecraft, Falcon 9 rocket and supporting ground systems.  

The review was the seventh milestone for SpaceX under CCiCap. The company is on track to complete all 15 of its CCiCap milestones by the summer of 2014. All of NASA's industry partners, including SpaceX, continue to meet their established milestones in developing commercial crew transportation capabilities.

NASA - Sierra Nevada Corporation Dream Chaser Testing Begins at NASA Dryden, Langley

SNC Dream Chaser Testing Begins at NASA's Dryden, Langley

Sierra Nevada Corporation's (SNC) Space Systems Dream Chaser flight vehicle arrived at NASA's Dryden Flight Research Center in Edwards, Calif., Wednesday to begin tests of its flight and runway landing systems.

 The tests are part of pre-negotiated, paid-for-performance milestones with NASA's Commercial Crew Program (CCP), which is facilitating U.S.-led companies' development of spacecraft and rockets that can launch from American soil. The overall goal of CCP is to achieve safe, reliable and cost-effective U.S. human access to and from the International Space Station and low-Earth orbit.

 Tests at Dryden will include tow, captive-carry and free-flight tests of the Dream Chaser. A truck will tow the craft down a runway to validate performance of the nose strut, brakes and tires. The captive-carry flights will further examine the loads it will encounter during flight as it is carried by an Erickson Skycrane helicopter. The free flight later this year will test Dream Chaser's aerodynamics through landing. 

 Meanwhile, on the east coast, several NASA astronauts will be at the agency's Langley Research Center in Hampton, Va., this week to fly simulations of a Dream Chaser approach and landing to help evaluate the spacecraft's subsonic handling. The test will measure how well the spacecraft would handle in a number of different atmospheric conditions and assess its guidance and navigation performance.

 "Unique public-private partnerships like the one between NASA and Sierra Nevada Corporation are creating an industry capable of building the next generation of rockets and spacecraft that will carry U.S. astronauts to the scientific proving ground of low-Earth orbit," said William Gerstenmaier, NASA's associate administrator for human exploration and operations in Washington. "NASA centers around the country paved the way for 50 years of American human spaceflight, and they're actively working with our partners to test innovative commercial space systems that will continue to ensure American leadership in exploration and discovery." 

 The Dream Chaser Space System is based on Langley's Horizontal Lander HL-20 lifting body design concept. The design builds on years of analysis and wind tunnel testing by Langley engineers during the 1980s and 1990s. Langley and SNC joined forces six years ago to update the HL-20 design in the Dream Chaser orbital crew vehicle. In those years, SNC worked with the center to refine the spacecraft design. SNC will continue to test models in Langley wind tunnels. Langley researchers also helped develop a cockpit simulator at SNC's facility in Louisville, Colo., and the flight simulations being assessed at the center. 

 NASA is partnered with SNC, Space Exploration Technologies (SpaceX) and The Boeing Company to meet CCP milestones for integrated crew transportation systems under the Commercial Crew Integrated Capability (CCiCap) initiative. Advances made by these companies under their funded Space Act Agreements ultimately are intended to lead to the availability of commercial human spaceflight services for government and commercial companies. 

 While NASA works with U.S. industry partners to develop commercial spaceflight capabilities, the agency also is developing the Orion spacecraft and the Space Launch System (SLS), a crew capsule and heavy-lift rocket to provide an entirely new capability for human exploration. Designed to be flexible for launching spacecraft for crew and cargo missions, SLS and Orion will expand human presence beyond low-Earth orbit and enable new missions of exploration in the solar system.
