COLORADO SPRINGS — As Sierra Nevada Corporation (SNC) prepares its Dream Chaser cargo vehicle for a first launch on an Atlas 5 in late 2020, the company expects to make a decision by the end of this year on the rocket that will launch later missions.

At a briefing during the 34th Space Symposium here April 18, company officials said development of the cargo version of Dream Chaser is on schedule for a first launch in the fourth quarter of 2020. That mission, the first of at least six missions to the International Space Station under a NASA Commercial Resupply Services 2 contract awarded in January 2016, will launch on a United Launch Alliance Atlas 5.

"It is a very well proven rocket. We have a long relationship with United Launch Alliance," said Mark Sirangelo, executive vice president for SNC Space Systems. "We think it is a good way to start."

SNC announced a contract with ULA in July 2017 that covered two Dream Chaser launches, in 2020 and 2021. Both would use the Atlas 5 552, the largest version of the Atlas 5 with a five-meter payload fairing, five solid rocket boosters and a dual-engine Centaur upper stage.

However, Sirangelo said the company was looking at other options for launching the second and later Dream Chaser ISS cargo missions. "It's a quite interesting time in the launch business, where we see all the major launch companies coming out with a new launch system," he said. "We are looking at all of the launch systems."

Sirangelo said later that the company issued a request for proposals for multiple Dream Chaser launches. "We'll probably be making a decision by the end of this year," he said. "We're gotten tremendous response for it." He declined to discuss specific vehicles under consideration but said SNC received "really great response from all the major providers."

He noted that there are no requirements under its NASA contract that require those cargo missions to fly on U.S. vehicles, citing NASA's use of European and Japanese cargo vehicles to resupply the ISS. "We think it's certainly feasible," he said, adding that there was interest in launching Dream Chaser on vehicles outside the U.S.

The Dream Chaser cargo vehicle is currently going through its critical design review (CDR), said Steve Lindsey, vice president at SNC Space Exploration Systems. That review should be completed by July.

Production of the first vehicle will soon start, even as the CDR is still being finalized. "The first parts of our primary structure are arriving next month," he said. "We're marching along really well with that."

SNC held the briefing in front of the Dream Chaser engineering test article that performed a glide flight at Edwards Air Force Base in California in November. That test article, developed under earlier NASA commercial crew awards, will now be placed in "flyable storage" at the company's Colorado facilities.

Lindsey said the company will likely keep the test article in storage until the company is ready to resume development of a crewed version of Dream Chaser. "We're going to keep it in a condition ready to fly," he said. "We'll modify it for flying crew, put a pilot in there and do some testing in the future."

ЦитироватьDREAM CHASER® SPACECRAFT PASSES KEY NASA MILESTONE PRODUCTION OF ORBITAL SPACECRAFT TO BEGIN

SPARKS, Nev.,  December 18, 2018 – Sierra Nevada Corporation's (SNC) Dream Chaser spacecraft passed a key milestone for NASA'S Commercial Resupply Services 2 (CRS-2) contract, validating design performance and clearing the way for full spacecraft production. The milestone marks completion of Integration Review 4 (IR4) demonstrating NASA's confidence in the safety and maturity of Dream Chaser's design.

"NASA's acknowledgement that SNC has completed this critical milestone and its approval of full production of the first Dream Chaser spacecraft is a major indication we are on the right path toward increasing vital science return for the industry," said John Curry, program director for CRS-2 under SNC's Space Systems business area.

Many critical parts of the orbital vehicle are already complete, built and being tested, including major structural components, thermal protection system tiles and avionics hardware. With the success of IR4, these components are now being integrated into the orbital vehicle assembly at SNC's Space Systems facilities in Louisville, CO.

Subject matter experts from NASA and SNC thoroughly reviewed the Dream Chaser spacecraft design and its integrated performance with launch, ground and flight elements. Based on system capabilities, design maturity and the extensive data products presented, SNC and NASA jointly concluded the Dream Chaser program was ready to move to full-scale spacecraft manufacturing and testing.

SNC's Dream Chaser spacecraft is slated to service the International Space Station as early as late 2020. Production includes both the uncrewed Dream Chaser winged vehicle and the cargo module, which remains attached to the winged vehicle during orbital operations.

"We are one step closer to the Dream Chaser spacecraft's first orbital flight. This comprehensive review approved moving the Dream Chaser program into the production phase so we can get Dream Chaser to market as a critical space station resupply spacecraft as soon as possible," said Fatih Ozmen, co-owner and CEO of SNC. "IR4 was a series of reviews, documentation, and data deliverables that are the culmination of many years of design work, analysis and development testing."

The Dream Chaser will perform at least six missions to provide cargo resupply, disposal and return services to the International Space Station under NASA's CRS-2 contract. The spacecraft delivers up to 5,500kg (~12,100lbs) of pressurized and unpressurized cargo and returns over 1,850 kg (~4,000lbs) of cargo with a gentle runway landing. The spacecraft also provides approximately 3,400kg (~7,400 lbs) of disposal capability each mission via the cargo module, which burns up in the atmosphere after separation from the Dream Chaser winged vehicle.

SNC, though, is keeping its launch options open for future Dream Chaser missions. "We're looking at all launch vehicles out there," Steve Lindsey, vice president for space exploration systems at the company, said during a panel discussion Oct. 11 at the International Symposium for Personal and Commercial Spaceflight in Las Cruces, New Mexico.

Competition in the launch market has helped drive down costs for SNC. "When those launch vehicle prices come down — which, by the way, is about 80 percent of our costs on every mission we fly — that opens up the commercial market," he said. That includes other applications of Dream Chaser, such as a free-flying experiment platform.

At that conference, Lindsey said he expected to be "the majority of the way through" assembly and testing of the first Dream Chaser by next October, while planning "changes and upgrades" for a second vehicle.

Dream Chaser to Use Europe's Next-Generation Docking System

 April 6, 2017  Doug Messier 

PARIS (ESA PR) — ESA and a team of European industrial contractors led by QinetiQ have finalised an agreement with Sierra Nevada Corporation for the use of Europe's International Berthing Docking Mechanism on the Dream Chaser spaceplane.

The Sierra Nevada Corporation (SNC) Dream Chaser is being developed as a reusable, lifting-body, multi-mission spacecraft capable of landing at commercial airports or spaceports that can accommodate large commercial aircraft anywhere in the world.

Sel ected to provide cargo delivery, return and disposal services for the International Space Station under NASA's Commercial Resupply Services 2 contract, it is a safe, affordable, flexible and reliable system, designed to provide crewed and uncrewed transportation services to low orbit destinations, such as the Space Station and future commercial space infrastructures.

The International Berthing Docking Mechanism (IBDM) is an androgynous, contact force-sensing, low-impact docking system, capable of docking and berthing large and small vehicles.

The IBDM consists of the Soft-Docking System and the Hard-Docking System. The first captures and actively dissipates the kinetic energy of the two spacecraft. The second makes the structural pressurised connection between the spacecraft.

The IBDM is fully compatible with the International Docking System Standard (IDSS) defined by the Station partner agencies and with the new docking ports being made available at the Station.

ESA developed the docking system in cooperation with NASA, with the goal of building a modern docking system for space vehicles visiting the Station after the Space Shuttle's retirement.

The dual active control loop markedly improves on existing technology by reducing the docking forces on the space infrastructure and by enabling the capture and docking of a wide range of spacecraft mass and flight envelopes.

QinetiQ has been leading IBDM development since the beginning and it has set up an industrial team including SENER (Spain and Poland), responsible for the Hard-Docking System, Ruag AG (Switzerland) for the linear actuators, and Maxon (Switzerland) for the electric motors.

 August 4, 2016  Doug Messier

SACRAMENTO, Calif., Aug. 02, 2016 (Aerojet Rocketdyne PR) — Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), has been awarded a contract from Sierra Nevada Corporation (SNC) to supply the electrical power system for the Dream Chaser, a commercial spacecraft that will carry cargo to and from the International Space Station. The system will regulate power generated from the solar arrays and distribute it to the reusable spacecraft's avionics, thermal and propulsion systems, as well as payloads that require electrical power.

"Aerojet Rocketdyne is honored to supply a critical power-management system for a spacecraft that will deliver supplies to astronauts living and working onboard the space station," said Aerojet Rocketdyne CEO and President Eileen Drake. "We have been instrumental in efficiently and effectively managing power on the station for decades. We look forward to building upon that experience with Sierra Nevada Corporation, and developing future power systems for use on commercial missions, as well as NASA exploration programs and in-space transportation."

"The capacity of the rechargeable batteries will allow Dream Chaser to increase its free-flight time in space, as well as support the spacecraft's cargo delivery and return journey back to Earth," said Julie Van Kleeck, vice president of Advanced Space and Launch at Aerojet Rocketdyne. "We are proud to be able to provide a low-cost solution for the commercial spacecraft's electrical power system."

Aerojet Rocketdyne will design, develop, fabricate, test and integrate SNC's Dream Chaser electrical power system, including power conversion, distribution units and rechargeable batteries.

ESA to Invest in Sierra Nevada's Dream Chaser

January 22, 2016  Doug Messier 

Sierra Nevada Corporation is receiving an investment fr om ESA for its Dream Chaser spacecraft:

Once the agreement is signed, ESA will begin work building the first flight model of the International Berthing and Docking Mechanism (IBDM), which Sierra Nevada's Dream Chaser Cargo System will use to attach itself to the space station.

ESA said it would spend 33 million euros ($36 million) to complete the design of the IBDM and build a flight model for Dream Chaser's first cargo run. Future IBDMs will be financed by Sierra Nevada, ESA said.

ESA and Sierra Nevada in early 2014 agreed to adapt the IBDM to Sierra Nevada's winged Dream Chaser, which was originally designed to carry astronauts and more recently has been adapted for unmanned cargo missions.

The agency spent about 8 million euros on the early work, which slowed after Sierra Nevada failed to win a NASA contract to send commercial crews to the space station.

ESA said it had spent some 20 million euros in total in recent years working on IBDM and on preparatory work for Dream Chaser.

А они что полностью одинаковые по задачам? Для запуска используется один и тот же РН? Нет, конечно скорость запуска пилотируемого Союза после аварии РН впечатляет. Покупается у одного и того же поставщика, а не создается типа конкуренция с уменьшением цены заказчику? (конечно от количества изменяется и цена)

ЦитироватьDREAM CHASER® SPACECRAFT PASSES ANOTHER NASA MILESTONE

Ground and Flight Operations Enabled, First Flight in 2021

SPARKS, Nev., March 21, 2019 – Sierra Nevada Corporation's (SNC) Dream Chaser spacecraft passed NASA's Integrated Review Milestone 5 (IR5), a key status check on SNC's performance of a variety of ground and flight operations.

IR5 demonstrates that the Dream Chaser team is on track to operate the space vehicle in advance of the first mission to the International Space Station under the Commercial Resupply Services Contract 2 (CRS-2).

"This milestone is a great accomplishment for the team focused on operations development and demonstration. It shows we can operate the Dream Chaser from the ground, including getting critical science in and out of the vehicle," said John Curry, CRS-2 program director within SNC's Space Systems business area.

The review included development of the vehicle's flight computers and software, mission simulator and Mission Control Center. SNC also performed cargo demonstrations using high fidelity mock-ups of the vehicle and its cargo module, showing loading and unloading time and efficiency.

Milestone testing took place at SNC's Louisville, Colorado and NASA Kennedy Space Center facilities. Data was also used from the Dream Chaser 2017 free-flight test at Edwards Air Force Base, California, with the help of NASA's Armstrong Flight Research Center.

"Our Dream Chaser team continues to successfully execute milestones as we move closer to getting this spacecraft into space," said Fatih Ozmen, SNC's owner and CEO. "The orbital spacecraft is being built and this milestone demonstrates the vehicle keeps passing key reviews and is making great strides."

Dream Chaser continues to meet technical and scheduled milestones on its way to first flight in spring 2021. The Dream Chaser will conduct at least six orbiting flights to the space station, delivering equipment and supplies to advance space exploration and then safely return life science and other time-critical items on a conventional runway.
