Надо же - у шаттла тоже было это "достоинство".  И где теперь его достоинство?

У Шаттла кроме этого был еще и недостаток - его размер... И уязвимая ТЗ. И электроника 70х годов... И тем не менее - он летал больше чем КК "Союз" всех модификаций...

DREAM CHASER® SPACECRAFT PRIMARY STRUCTURE ARRIVES IN COLORADO
Most Advanced High-Temperature Composite Spaceframe

SPARKS, Nev., October 15, 2019 – Sierra Nevada Corporation (SNC), the global aerospace and national security leader owned by Chairwoman and President Eren Ozmen and CEO Fatih Ozmen, announces the arrival of the primary vehicle structure to the company's Colorado production facility, kicking off full assembly of the Dream Chaser® spacecraft ahead of its first mission for NASA in 2021.  The structure is the largest piece of technology to make up Dream Chaser and the most advanced high-temperature composite spaceframe ever built.

"It's an extraordinary engineering and manufacturing accomplishment," said Eren Ozmen, chairwoman and president of SNC. "Our team has been looking forward to this day for a long time so that we can fully assemble America's spaceplane in preparation for its first mission for NASA."

The primary structure is a pressurized composite structure that will contain pressurized payloads heading to the International Space Station. The structure was manufactured by subcontractor Lockheed Martin and recently shipped fr om their Fort Worth, Texas facility to Louisville, Colorado, wh ere Dream Chaser is being built and integrated by SNC.

"As the first building block of the spacecraft, it represents the first critical path hardware to be received in Colorado and launch of the assembly, integration and test (AI&T) phase of the program," said former NASA space shuttle commander, astronaut and retired USAF pilot Steve Lindsey, now senior vice president of strategy for SNC's Space Systems business area.  "Dream Chaser is truly a state-of-art vehicle with cutting edge technology. This structure exemplifies its unique design and complexity."

Highlights about the design:

[/li]
• Uses advanced composite 3D woven assembly methods and represents the most advanced high-temperature composite spaceframe ever built.
  
• Structure is about 30 feet long by 15 feet wide and approximately 6 feet high and weighs roughly 2,200 pounds.
  
• Materials include carbon fiber reinforced polymers (CFRPs), more traditionally referred to as "composites."
  
• The use of CFRP materials instead of aluminum and titanium alloys, lowers manufacturing costs for creating a unique, aerodynamically complex spaceframe design.
  
• Composites decrease the amount of thermal protection required compared to an aluminum primary structure.
  
• Advanced 3D woven construction minimize penetrations to the hot lower aeroshell.
  

Dream Chaser is scheduled to launch starting in late 2021 for at least six cargo resupply and return services to the International Space Station for NASA under the Commercial Resupply Services 2 (CRS-2) contract.  The Dream Chaser Cargo System can carry up to 12,000 pounds of supplies and other cargo, and returns delicate science to Earth with a gentle runway landing.

SNC'S "SHOOTING STAR" ARRIVES AT NASA'S KENNEDY SPACE CENTER

SPARKS, Nev., November 19, 2019 – Sierra Nevada Corporation (SNC), the global aerospace and national security leader owned by Eren and Fatih Ozmen, delivered a test version of its Shooting Star cargo module to NASA's Kennedy Space Center for testing ahead of its planned launch with SNC's Dream Chaser® spacecraft in 2021.

Shooting Star is a 15-foot attachment to Dream Chaser that will be used on NASA's Commercial Resupply Services 2 (CRS-2) contract to provide extra storage for payloads and to facilitate cargo disposal upon re-entry into Earth's atmosphere.

"With the addition of Shooting Star we add a capability for NASA, sending even more critical science, food and cargo to the International Space Station, and contributing to the important work the astronauts are doing every day," said Eren Ozmen, SNC's Chairwoman and President.

Dream Chaser will execute its first of at least six launches to the International Space Station in fall of 2021 under the CRS-2 contract.  The cargo module will carry an additional 10,000 pounds of pressurized and unpressurized payloads to the International Space Station.

A key capability for Dream Chaser is performing cargo disposal upon re-entry. SNC's Shooting Star cargo modules will burn up in the earth's atmosphere, discarding unwanted material offloaded from the International Space Station.

"Shooting Star's ability to deliver additional cargo and provide a disposal service makes it and Dream Chaser extremely effective and versatile," said former NASA space shuttle commander and retired USAF pilot Steve Lindsey, now senior vice president of strategy for SNC's Space Systems business area.

For additional versatility, Shooting Star can support logistics services to other LEO destinations, including future commercial outposts, and for the lunar Gateway. SNC has also developed a concept for a free flying version that can act as a satellite to carry large payloads, with high-power capacity.

A "Shooting Star" was unveiled Tuesday, Nov. 19, at Kennedy Space Center.

During a media event held in the Florida spaceport's Space Station Processing Facility high bay, former NASA astronaut and current Senior Vice President of Strategy for Sierra Nevada Corporation (SNC) Space Systems Steve Lindsey revealed the name of the cargo module that will attach to the back of the company's Dream Chaser spacecraft: Shooting Star.

"It's an exciting day for us," said Lindsey, a veteran of five NASA shuttle missions.

Shooting Star is a 15-foot-long cargo module that will attach to the back of the 30-foot-long Dream Chaser. It will be used to deliver more than 12,000 pounds of supplies and other cargo for NASA to the International Space Station as part of the Commercial Resupply Services-2 (CRS-2) contract. Its first flight is scheduled to launch fr om Kennedy in fall 2021.

"Sierra Nevada Corporation is excited to be expanding our footprint here at Kennedy Space Center," said Kimberly Schwandt, senior communications manager for SNC Space Systems.

Dream Chaser will fly back to Earth and land on the runway at Kennedy's Launch and Landing Facility, formerly the Shuttle Landing Facility. Shooting Star will have a different fate. It will carry unwanted cargo from the space station, disposing of it while burning up upon re-entry into Earth's atmosphere. The process of "burning up" is wh ere the Shooting Star name came from, Lindsey explained.

"The cargo module is really interesting because it's kind of the unsung hero of the whole Dream Chaser cargo system design," Lindsey said, while standing in front of a Shooting Star testing mockup. "It has a very unique shape — notice how it angles in as you go higher. It's shaped to handle external and internal payloads."

Payload capability includes pressurized and unpressurized cargo. Though it was designed specifically for cargo resupply services to the space station, Shooting Star can have many other applications, Lindsey said, including carrying crew, operating as a free-flying satellite and going from low-Earth to lunar orbit.

"It's a pretty versatile system," Lindsey said, "and the more we worked on it, the more we realized there are multiple applications for it."

The Shooting Star mockup was recently delivered to Kennedy from SNC's facility in Colorado. It will remain at the Florida spaceport, Lindsey said, for testing, processing and training of flight controllers.

NASA selected Dream Chaser for the CRS-2 contract, which involves launching six cargo missions to the space station by 2024.
