‘Dream Chaser’ mini spaceplane hoisted over Mojave Desert

A test version of a spacecraft resembling a mini space shuttle was carried aloft over the Mojave Desert by a helicopter Wednesday in a precursor to a free flight in which it will be released to autonomously land on a runway as it would in a return from orbit.

Sierra Nevada Corp.’s Dream Chaser craft was lifted off the ground at 7:21 a.m., at NASA’s Armstrong Flight Research Center on Edwards Air Force Base, California, and was carried to the same altitude and flight conditions it will experience before release in a free flight.

A control team sent commands to the wingless vehicle and collected data before the helicopter brought it down at 9:02 a.m., the company said.

‘Everything we have seen points to a successful test with useful data for the next round of testing,’ director of flight operations Lee ‘Bru’ Archambault said in a statement.

A second captive-carry test is scheduled this year and if it is successful, a free flight test will follow.

The Dream Chaser is being developed to carry cargo to and from the International Space Station without a crew aboard. 

The version flown Wednesday is for tests in the atmosphere. 

The version that will be launched into space is still in development.

With the addition of life-support equipment, a Dream Chaser could transport a crew of seven.

Last month, Sierra Nevada selected United Launch Alliance’s Atlas 5 rocket to launch the first two Dream Chaser cargo missions, which are scheduled to blast off from Cape Canaveral, Florida, in 2020 and 2021. Those missions will land at Kennedy Space Center. 

‘Fans disconsolate after retirement of NASA’s shuttle fleet can take heart: The next generation in reusable space vehicles is set to debut,’ NASA has said.

NASA says the ‘guiding principles’ for the craft are ‘Fly frequently, travel safely, land on (most) runways, and operate economically’.

It plans to use the craft, called Dream Catcher, as a cargo-carrying aerospace workhorses routinely launching to low-Earth orbit for space station resupply and crew transfers.

In January 2016 SNC was one of three companies awarded contracts to ferry cargo from 2019 through 2024 to the International Space Station (ISS). 

Under the terms of NASA’s Commercial Crew Program, and as part of a Space Act Agreement, SNC is able to use agency wind tunnels for Dream Chaser studies and experiments. 

That’s where Langley came in, mounting a Dream Chaser scale model in its Unitary Plan Wind Tunnel for extensive aerodynamic data gathering, which was subsequently added to the spacecraft’s performance database.

Although a quarter of the size of any of the now-retired space shuttles, Dream Chaser can carry as many as seven crew members. 

Although there is but one basic spacecraft airframe, there are two system variants optimized for either manned or unmanned missions. 

SNC says the Dream Chaser can be reused 15 or more times, more than any other current operational space vehicle.

The company also touts the spacecraft’s flexibility in remote sensing, satellite servicing, and even ‘active debris removal,’ otherwise known as space-trash cleanup.

A second round of Dream Chaser flight tests at NASA’s Armstrong Research Center is slated to continue through the end of the 2017 calendar year.

The test campaign will help SNC validate the aerodynamic properties, flight software and control system performance of the Dream Chaser.

It is being prepared to deliver cargo to the International Space Station under NASA’s Commercial Resupply Services 2 (CRS2) contract beginning in 2019.

The data that SNC gathers from this test campaign will help influence and inform the final design of the cargo Dream Chaser, which will fly at least six cargo delivery missions to and from the space station by 2024.

Last year NASA  announced Sierra Nevada Corp. will join SpaceX and Orbital ATK in launching cargo to the International Space Station.

These flights, yet to be finalized, will run through 2024, and marks a second chance for the Nevada-based company, which is developing a mini shuttle called Dream Chaser. 

Sierra Nevada competed for NASA’s commercial crew contract, but lost out in 2014 to SpaceX and Boeing.

The new spaceplane stage has been set by decades of NASA work done at Langley Research Center on horizontal-landing, or HL, lifting bodies. 

Sporting a design reminiscent of the upward-flexing pectoral fins on breaching manta rays, HL vehicles feature rudimentary wings. 

As the craft settles through Earth’s atmosphere from orbit the chubby, cigar-like fuselage generates lift from more air pressure on the bottom than on the top.

Flying Wingless First championed for flight testing by NASA engineer H. Dale Reed in the early 1960s, the HL concept went through a number of design changes and improvements, eventually resulting in a series of experimental piloted aircraft. 

The Northrop HL-10 – referring to the tenth design evaluated by Langley engineers – was built to assess specific structural refinements. Langley laboratories and wind tunnels hosted a variety of early studies on scale models before any full-scale craft were constructed.

The HL-10 would be one of five ‘heavyweight’ lifting body designs flown at NASA’s Flight Research Center (now known as Armstrong Research Center) from July 1966 to November 1975 to demonstrate a pilot’s ability to maneuver and safely land a wingless vehicle. 

The information the lifting-body program generated contributed to a database crucial to the genesis of the space shuttle program.

A New Kid Spurred by the Soviet Union’s development of its subscale, unmanned BOR-4 – a testbed for the country’s would-be Buran space shuttle – by the 1980s Langley had set to work on a HL-10 successor, known as the HL-20, or ‘Personal Launch System (PSL).’  

By 1990s, a 29-foot full-size, non-flying HL-20 model was built by the students and faculty of North Carolina State University and North Carolina A & T University to study crew-seating arrangements, habitability, equipment layout and how best to enter and exit. 

Although never flight-tested, the PSL did ultimately deliver: its design would be the basis for development of Sierra Nevada’s Corporation’s (SNC) Dream Chaser.

HISTORY OF THE NASA SHUTTLE PROGRAMME

The Space Shuttle Discovery is launched on Mission STS-29, March 13,1989

Born with Columbia, it was Nasa’s longest-running space exploration programme. 

Atlantis was launched in 1985. 

The next-to-youngest in Nasa’s fleet remains at Kennedy Space Center as a museum display.

This grand finale came 50 years to the day that Gus Grissom became the second American in space, just half a year ahead of Glenn.

Atlantis – the last of Nasa’s three surviving shuttles to retire – performed as admirably during descent as it did throughout the 13-day flight. 

A full year’s worth of food and other supplies were dropped off at the space station, just in case the upcoming commercial deliveries get delayed. 

The international partners – Russia, Europe, Japan – will carry the load in the meantime.

Not all 1,333 days in space have been a success, however.

Two of the shuttles – Challenger and Columbia – were destroyed, one at launch, the other during the ride home. 

Fourteen lives were lost. 

Yet each time, the shuttle programme persevered.

The decision to cease shuttle flight was made seven years ago, barely a year after the Columbia tragedy. 

President Barack Obama put paid to President George W. Bush’s lunar goals, however, opting instead for astronaut expeditions to an asteroid and Mars.

The space shuttle was sold to America as cheap, safe and reliable. It was none of those.

It cost $196billion over 40 years, ended the lives of 14 astronauts and managed to make less than half the flights promised.

Nasa’s first space shuttle flight was in April 1981. 

Now Atlantis has landed, it and the other two remaining shuttles are officially museum pieces – more expensive than any paintings.

The total price tag for the programme was more than twice the $90billion Nasa originally calculated.

Atlantis undocked  from the International Space Station in September 2006.

But as a mistake it is one that paid off in wildly unexpected ways that weren’t about money and reliability.

Former president George Bush Sr said: ‘The discoveries it enabled, the international co-operation it fostered and the knowledge it gained – often at great human cost – has also contributed in countless, important ways to humanity and our common progress.’

Mr Bush oversaw the programme’s early days as vice-president, a job that has traditionally included supervising Nasa.

University of Colorado science policy professor Roger Pielke Jr., who studies shuttle costs and policies, said there are probably other ways the U.S. could have spent several billion dollars a year on a human space programme and gained more.

When the shuttle succeeded, it did so in a spectacular way.

But its failures were also large and tragic. 

Seven astronauts died when Challenger exploded about a minute after launch in 1986 and seven more died when Columbia burned up as it returned to Earth in 2003.

Last-ditch appeals to keep shuttles flying by such Nasa legends as Apollo 11’s Neil Armstrong and Mission Control founder Christopher Kraft landed flat.
