Release 14-287 New Commercial Rocket Descent Data May Help NASA with Future Mars Landings

NASA successfully captured thermal images of a SpaceX Falcon 9 rocket on its descent after it launched in September from Cape Canaveral Air Force Station in Florida. The data from these thermal images may provide critical engineering information for future missions to the surface of Mars.

"Because the technologies required to land large payloads on Mars are significantly different than those used here on Earth, investment in these technologies is critical," said Robert Braun, principal investigator for NASA's Propulsive Descent Technologies (PDT) project and professor at the Georgia Institute of Technology in Atlanta. "This is the first high-fidelity data set of a rocket system firing into its direction of travel while traveling at supersonic speeds in Mars-relevant conditions. Analysis of this unique data set will enable system engineers to extract important lessons for the application and infusion of supersonic retro-propulsion into future NASA missions."

NASA equipped two aircraft with advanced instrumentation to document re-entry of the rocket's first stage. The first stage is the part of the rocket that is ignited at launch and burns through the rocket's ascent until it runs out of propellant, at which point it is discarded from the second stage and returns to Earth. During its return, or descent, NASA captured quality infrared and high definition images and monitored changes in the smoke plume as the engines were turned on and off.

"NASA's interest in building our Mars entry, descent and landing capability and SpaceX's interest and experimental operation of a reusable space transportation system enabled acquisition of these data at low cost, without standing up a dedicated flight project of its own," said Charles Campbell, PDT project manager at NASA's Johnson Space Center in Houston.

NASA's Scientifically Calibrated In-Flight Imagery (SCIFLI) project team at NASA's Langley Research Center in Hampton, Virginia, had their eyes, cameras and telescopes trained on the Falcon with the help of two long-range aircraft provided by NASA and the U.S. Navy.

A NASA WB-57, a twin jet engine high-altitude research aircraft from Johnson, was equipped with a long-range infrared optical system to capture the images. It is a unique full-motion video camera system that is gimbal-mounted on the nose of the WB-57. It collects full-color high definition and infrared video.

A Navy NP-3D Orion aircraft from the Naval Air Systems Command Weapons Division's Air Test and Evaluation Squadron-30 at Point Mugu, California, was equipped with a long-range infrared optical system and also took thermal images of the launch.

On launch day, the WB-57 and NP-3D Orion reached their observation locations about 50 miles from the projected rocket trajectory. After launch, the rocket emitted enough thermal energy for the plane's infrared cameras to catch a glimpse. Both flight crews then worked to obtain data as the first stage descended at supersonic speeds off the coast of Georgia.

"Through our partnership with SpaceX we're gaining access to real-world test data about advanced rocket stage design and retro-propulsion," said Michael Gazarik, NASA's associate administrator for Space Technology at NASA Headquarters in Washington. "Through this partnership we're saving the taxpayer millions of dollars we'd otherwise have to spend to develop and test rockets and flights in-house. This is another great example of American companies partnering with NASA to enable our future exploration goals."

This research and technology effort is funded by the Game Changing Development program in NASA's Space Technology Mission Directorate (STMD). STMD builds, tests and flies technologies needed for the aerospace missions of tomorrow and continues to solicit the help of the best and brightest minds in academia, industry, and government to drive innovation and enable solutions in important technology thrust areas. These planned investments address high priority challenges for achieving safe and affordable deep space exploration.

RELEASE 14-290 NASA Partners with Leading Technology Innovators to Enable Future Exploration

Recognizing that technology drives exploration, NASA has selected four teams of agency technologists for participation in the Early Career Initiative (ECI) pilot program. The program encourages creativity and innovation among early career NASA technologists by engaging them in hands-on technology development opportunities needed for future missions.

NASA’s Space Technology Mission Directorate created the ECI to enable a highly collaborative, joint-partnering work environment between the best and brightest NASA early career innovators and leading innovators in industry, academia and other government organizations.

"Continued investment in technology is a requirement for the success of NASA's current and future missions," said Michael Gazarik, associate administrator for Space Technology at NASA Headquarters in Washington. "Investing in the future leaders in space technology in partnership with the nation’s leading innovators is part of our overall portfolio strategy for mission success."

RELEASE 14-291 Boeing Concludes Commercial Crew Space Act Agreement for CST-100/Atlas V

Boeing has successfully completed the final milestone of its Commercial Crew Integrated Capability (CCiCap) Space Act Agreement with NASA. The work and testing completed under the agreement resulted in significant maturation of Boeing’s crew transportation system, including the CST-100 spacecraft and Atlas V rocket.

NASA in July approved the Critical Design Review Board milestone for Boeing’s crew transportation system, confirming the detailed designs and plans for test and evaluation form a satisfactory basis to proceed with full-scale fabrication, assembly, integration and testing. It is the culmination of four years of development work by Boeing beginning when the company partnered with NASA during the first round of agreements to develop commercial crew transportation systems. To get to this point, extensive spacecraft subsystem, systems, and integrated vehicle design work has been performed, along with extensive component and wind tunnel testing.

Boeing is one of eight companies NASA partnered with during the last four years to develop a human-rated transportation system capable of flying people to low-Earth orbit and the International Space Station. NASA’s unique approach encouraged companies to invest their own financial resources in the effort and open up a new industry of private space travel. Other current NASA partners Blue Origin, Sierra Nevada Corporation and SpaceX all are deep in development of their own commercial crew transportation systems under separate Space Act Agreements.

NASA's spaceflight specialists from a variety of technical expertise areas not only assisted the companies but also worked closely with them in judging progress and deciding whether milestones in the Space Act Agreements were met.

The partnership with Boeing began in 2010 when NASA selected the company as one of five awardees for the first phase of commercial crew development. NASA’s second round of development awards in April 2011 also included Boeing and called for the CST-100 crew transportation system design to be advanced to the preliminary design review point.

The CCiCap initiative, the third phase of development, began in August 2012 when NASA announced an agreement with Boeing totaling $460 million to advance the design of the integrated transportation system. NASA added an optional milestone in 2013, bringing the total level of NASA investment in Boeing for CCiCap to $480 million.

Development work aligned with milestone goals of the initiative, and work took place at numerous locations across the country to take advantage of unique facilities. Engineering teams tested and modified mission flight software, including launch, docking, on-orbit, and re-entry and landing maneuvers. Teams conducted mission simulations to advance communications and mission operations planning.

Models of the CST-100 and the Atlas V launch vehicle were tested in wind tunnels. Launch abort engines and thrusters the spacecraft will use for maneuvering in space were test-fired. Work was done to refine the spacecraft and service module designs and make modifications required for human rating the existing commercially available United Launch Alliance Atlas V rocket. Ground systems design and operation included launch site modification plans for crews and pad workers. Landing and recovery details also were conceived, reviewed, tested and approved. All this work ensured Boeing’s crew transportation system matured to the verge of flight test article construction.

NASA's goal for the Commercial Crew Program is to facilitate the development of a U.S. commercial crew space transportation capability with the goal of achieving safe, reliable and cost-effective access to and from low-Earth orbit and the International Space Station. The next and final phase of commercial crew development was announced recently with the award of Commercial Crew Transportation Capability (CCtCap) contracts to Boeing and SpaceX. With the new contracts, NASA’s goal is to certify crew transportation systems in 2017 that will return the ability to launch astronauts from American soil to the International Space Station using privately built spacecraft.
