  • DreamChaser spaceplane update

    Adding credibility to their statements is that Sierra Nevada got the largest share of a $50 million CCDev Space Act grant just for the development of DreamChaser.

    Ain't she purdy?

    DC could launch on an Atlas V, Delta IV or a Falcon 9 or Falcon 9 Heavy. She's based on the HL-20 that NASA originally planned to be the crew-taxi backup for the Shuttle if it had to be grounded, but it was canceled when Congress cut their funds. NASA sold the concept to SpaceDev, which was later acquired by proven space systems developer Sierra Nevada. Along with all of NASA's stuff they also got an HL-20, so they aren't starting from zero. In fact they started 2-3 years ago with modernizing its systems and materials.

    In the picture above Sierra Nevada Corporation's Dreamchaser reusable vehicle concept docks with the International Space Station. Of NASA's five Commercial Crew Development initiative funded space act agreements announced on 2 February Sierra Nevada won the largest sum, $20 million out of a total fund of $50 million

    Sierra Nevada's Mark Sirangelo told Hyperbola: "We are planning to mature our rocket motor system and develop an early prototype drop test vehicle under this programme and supplementing it with our own resources. It is only an eight month programme in its current form. Our programme goal is to have a usable orbital vehicle in service by 2014. The vehicle will take seven crew and critical cargo to and from [low Earth orbit] destinations and be able to land on a 3,000m [9,800ft] runway. Our team consists of seven prominent space companies and universities all with considerable experience."

    The feasibility of integrating Dream Chaserâ„¢ spacecraft on Atlas V launch vehicle has been investigated at a preliminary level, and found to be promising. The preferred configuration identified in this study is a fully-fueled Dream Chaserâ„¢ installed without a fairing on top of an Atlas x22. The Atlas x22 vehicle includes a dual-engine Centaur surrounded by a new cylindrical 3.8-m diameter fairing/interstage adapter, and two standard solid strap-on boosters. The primary launch site would be Launch Complex 41 at the CCAFS.

    Estimated performance of this vehicle is sufficient to carry 2,000 – 3,000 kg of internal cargo to the ISS, with expansion capability available by adding SRBs (up to a maximum of five). The Atlas V reliability record is exemplary; however, in the event of an ascent abort, this configuration appears to offer the best capability for a rapid, clean Dream Chaser™ separation. The cross-range capability of a fully-fueled Dream Chaser™ spacecraft gives it the ability to reach an acceptable landing site from an abort anywhere on the nominal trajectory and perform a normal runway landing. This includes an ability to abort directly off the launch pad to the nearby Shuttle Landing Facility.
