LAS VEGAS -- The Boeing Company tests the forward heat shield FHS jettison system of its CST-100 spacecraft at the Bigelow Aerospace facility in Las Vegas as part of an agreement with NASA's Commercial Crew Program CCP during Commercial Crew Development Round 2 CCDev2) activities. The FHS will protect the spacecraft's parachutes, rendezvous-and-docking sensor packages, and docking mechanism during ascent and re-entry. During a mission to low Earth orbit, the shield will be jettisoned after re-entry heating, allowing the spacecraft's air bags to deploy for a safe landing. In 2011, NASA selected Boeing for CCDev2 to mature the design and development of a crew transportation system with the overall goal of accelerating a United States-led capability to the International Space Station. The goal of CCP is to drive down the cost of space travel as well as open up space to more people than ever before by balancing industry’s own innovative capabilities with NASA's 50 years of human spaceflight experience. Six other aerospace companies also were selected to mature launch vehicle and spacecraft designs under CCDev2, including Alliant Techsystems Inc. ATK, Excalibur Almaz Inc., Blue Origin, Sierra Nevada Corp. SNC, Space Exploration Technologies SpaceX, and United Launch Alliance ULA. For more information, visit www.nasa.gov/commercialcrew.

Future work also will replace the antiquated communications, power and vehicle access resources with modern efficient systems. Some of the utilities and systems slated for replacement have been used since the VAB opened in 1965.

CAPE CANAVERAL, Fla. -- Media learn about the plans Space Exploration Technologies Corp. (SpaceX) has to take NASA astronauts to the International Space Station at Space Launch Complex-40 on Cape Canaveral Air Force Station. SpaceX is working to make its Falcon 9 rocket and Dragon capsule safe for humans for NASA's Commercial Crew Program (CCP) under the Commercial Crew Development Round 2 (CCDev2) activities. SpaceX already is developing these systems under NASA's Commercial Orbital Transportation System (COTS) Program to take supplies to the space station. Scott Henderson, director of SpaceX mission assurance, explained that the company is drafting designs to make the Dragon capsule crew-capable with life support systems while meeting CCP's safety requirements. One such option under discussion is a launch abort system that would push astronauts away from the launch pad in the event of an emergency, which is different than traditional pull systems. It's the freedom to develop innovative solutions such as this that CCP hopes will drive down the cost of space travel as well as open up space to more people than ever before. CCP, which is based at NASA's Kennedy Space Center in Florida, partnered with seven aerospace companies to mature launch vehicle and spacecraft designs under CCDev2, including Alliant Techsystems Inc. (ATK) of Promontory, Utah, Blue Origin of Kent, Wash., The Boeing Co., of Houston, Excalibur Almaz Inc. of Houston, Sierra Nevada Corp. of Louisville, Colo., Space Exploration Technologies (SpaceX) of Hawthorne, Calif., and United Launch Alliance (ULA) of Centennial, Colo.

DALLAS – This image was taken during a series of wind tunnel tests for Blue Origin's Space Vehicle at Lockheed Martin's High Speed Wind Tunnel Facility in Dallas. The Space Vehicle's innovative biconic shape is designed to provide more cross-range and interior volume than a traditional capsule and weigh less than a winged vehicle. More than 180 wind tunnel tests validated the company's analysis of the Space Vehicle's aerodynamics during descent through the atmosphere and the ability to change its flight path, which could increase the number of available landing opportunities and enhance the vehicle's emergency return capability.

Mango stuck to the social networking service's 140 character limit and answered dozens of questions. At left, is Brittani Sims, a member of the CCP team. The goal of CCP is to drive down the cost of space travel as well as open up space to more people than ever before by balancing industry’s own innovative capabilities with NASA's 50 years of human spaceflight experience. Seven aerospace companies are maturing launch vehicle and spacecraft designs under the program’s second round of development, called Commercial Crew Development Round 2 CCDev2), including Alliant Techsystems Inc. ATK, The Boeing Co., Excalibur Almaz Inc., Blue Origin, Sierra Nevada, Space Exploration Technologies SpaceX, and United Launch Alliance ULA. For more information, visit www.nasa.gov/commercialcrew.

DELAMAR DRY LAKE BED, Nev. – The Boeing Company's CST-100 crew capsule floats to a smooth landing beneath three main parachutes over the Delamar Dry Lake Bed near Alamo, Nev. This is the second parachute test that Boeing performed under its partnership with NASA's Commercial Crew Program CCP. The first showed the parachute system’s deployment scheme worked and that it could be re-packed and re-used for this second test. In 2011, NASA selected Boeing during Commercial Crew Development Round 2 CCDev2) activities to mature the design and development of a crew transportation system with the overall goal of accelerating a United States-led capability to the International Space Station. The goal of CCP is to drive down the cost of space travel as well as open up space to more people than ever before by balancing industry’s own innovative capabilities with NASA's 50 years of human spaceflight experience. Six other aerospace companies also are maturing launch vehicle and spacecraft designs under CCDev2, including Alliant Techsystems Inc.

LOUISVILLE, Colo. – Sierra Nevada Corporation Space Systems’ Dream Chaser full-scale test vehicle is lifted by an Erickson Air-Crane helicopter to verify proper aerodynamic flight performance near the Rocky Mountain Metropolitan Airport in Jefferson County, Colo. This captive-carry test is one of several milestones the company is meeting during its partnership with NASA’s Commercial Crew Program CCP. Data from this test will provide SNC an early opportunity to evaluate and prove hardware, facilities and ground operations in preparation for approach and landing tests scheduled for later this year.

LAS CRUCES, N.M. -- Pratt & Whitney Rocketdyne tests a thruster destined for Boeing's CST-100 spacecraft. The thruster was fired in a vacuum chamber that simulated a space-like environment of 100,000 feet at NASA's White Sands Test Facility in Las Cruces, N.M., to verify its durability in extreme heat, evaluate the opening and closing of its valves and confirm continuous combustion and performance. Twenty-four thrusters will be part of the spacecraft's orbital maneuvering and attitude control system OMAC, giving the CST-100 the ability to maneuver in space and during re-entry. The thrusters also will allow the spacecraft to separate from its launch vehicle if an abort becomes necessary during launch or ascent.
