Dream Chaser, NASA’s Artemis and extra

Sierra Nevada Company is finest generally known as a personal aerospace and nationwide safety contractor – however the firm is investing closely in its house methods division, particularly because it sees NASA and different corporations constructing infrastructure in orbit.

“Our view of the long run is a vibrant, business low Earth orbit economic system,” Steve Lindsey, SNC’s senior vp of technique house methods, instructed CNBC. “We need to be the logistics and crew suppliers in that future, so we’re actually enjoying the lengthy recreation.”

Whereas SNC so far has been concerned in tons of of exploration missions and extra, the crown jewel of its house portfolio is Dream Chaser: A reusable spacecraft that, in look resembling a miniaturized NASA House Shuttle, is constructed to launch atop a conventional rocket and land on a runway like an airplane.

“We view the Dream Chaser as one thing that finally in low Earth orbit shall be offering transportation, logistics and crew for everyone,” Lindsey mentioned.

Within the coming 12 months or so forward, SNC is concentrated on Dream Chaser’s first launch. The automobile SNC is constructing now could be optimized to hold cargo, somewhat than crew, and is beneath contract to fly provides and analysis to the Worldwide House Station for NASA.

Lindsey has been engaged on SNC’s Dream Chaser program for practically a decade. Whereas SNC had received greater than $360 million in improvement contracts from NASA beneath the aggressive Industrial Crew program, the company in 2014 ended up going with SpaceX and Boeing for additional contract awards. Regardless of the setback in creating a Dream Chaser as a crew automobile, SNC pivoted to focus the spacecraft on profitable contracts beneath NASA’s second technology of Industrial Resupply Providers program.

However SNC is constructing Dream Chaser to go far past the upcoming cargo missions.

“We see it as the long run automobile that shall be flying for the following 30, 40 or extra years,” Lindsey mentioned.

The corporate earlier this 12 months introduced the primary Dream Chaser is known as “Tenacity,” which Lindsey mentioned feels becoming amidst the challenges introduced on by the COVID-19 pandemic.

“2020 has been considerably tough 12 months for all of us, however we’re working by the challenges … and coming up with alternative ways of doing issues to maintain us on observe,” Lindsey mentioned.

SNC has been in a position to keep on schedule manufacturing the primary Dream Chaser spacecraft, he famous, with the corporate working a number of shifts a day. SNC is constructing each Dream Chaser, which might carry 4,080 kilos of provides, and the “Taking pictures Star” cargo that goes with it, which might carry an extra 11,000 kilos of cargo. One of many main meeting steps upcoming is to put in the wings on Dream Chaser, which Lindsey expects will occur early subsequent 12 months.

As soon as Dream Chaser and Taking pictures Star are constructed, then SNC will transfer to acceptance testing. That is the place SNC will bend and push the boundaries of the spacecraft’s construction, to copy the extraordinary bodily pressures of launching and reentering by the ambiance. Subsequent, SNC will take each spacecraft to Plum Brook Station, a facility at NASA’s Glenn Analysis Heart in Ohio. There the automobile shall be put in a thermal vacuum chamber and endure testing that simulates the setting of house, together with vibration and acoustic testing.

From Plum Brook, Lindsey mentioned SNC will ship the 2 spacecraft to NASA’s Kennedy House Heart in Florida, the place it can undergo last checks and processing earlier than launch.

SNC has confirmed “that the Dream Chaser construction is licensed for no less than 15 missions,” Lindsey mentioned. That is key to the corporate’s heavy funding within the spacecraft, as reuse will assist scale back its prices. Moreover, Lindsey famous that SNC is seeking to additionally certify its thermal safety system for 15 missions. This a part of the spacecraft consists of about 2,000 tiles that shield the spacecraft throughout re-entry into the ambiance, when temperatures can attain greater than 3,000 levels Fahrenheit. Lindsey, who flew 5 House Shuttle missions himself, famous that the Dream Chaser tiles “are a lot more durable than” those on NASA’s earlier spacecraft. Dream Chaser’s environmental management system will then assist maintain the temperature all the way down to what Lindsey described as a “shirtsleeves” stage, essential for flying delicate cargo in addition to individuals.

Dream Chaser additionally does not have any poisonous propellants on board. Whereas some spacecraft use what are generally known as hypergolic propellants, which Lindsey mentioned would have been simpler, the corporate prevented it “as a result of we wish to have the ability to land wherever on this planet {that a} 737 plane can and course of the automobile with none particular tools.”

The crew model of Dream Chaser is designed to fly as much as 5 astronauts. SNC goals to make Dream Chaser worth aggressive with others out there, with Lindsey saying that his firm needs “to be down nearer to what what SpaceX is concentrating on.” NASA expects SpaceX’s Crew Dragon capsule will price about $55 million per particular person.

“What’s actually attention-grabbing is that lots of the pricing actually depends upon the worth of the rocket,” Lindsey mentioned. “Our prices, working Dream Chaser by itself, aren’t that top. So what we’re excited to see is all of the issues which might be occurring [in the industry] – each single main launch firm is constructing new rockets to be extra worth aggressive. That is one of many issues that is required for the low Earth orbit economic system to take off, is these rocket costs drop.”

Presently United Launch Alliance, the three way partnership of Boeing and Lockheed Martin, is Dream Chaser’s launch supplier. SNC indicators a six mission cope with ULA to fly on the approaching Vulcan rocket, with the primary mission scheduled for subsequent 12 months.

“Our objective right here is to get this automobile to flight as quickly as we presumably can, however we additionally need to do it safely,” Lindsey mentioned.

SNC could not but communicate extra particularly to when launch day is scheduled, with Lindsey noting that the timing is “a negotiation between us and NASA.” However the company’s management final week stopped by SNC’s services in Louisville, Colorado, the place in addition they go to see Dream Chaser on the manufacturing ground.

That Dream Chaser could also be constructed for cargo, however 85% of its elements are the identical because the crew variation – with the construction additionally licensed for crew. 

“Now we have by no means misplaced observe of [flying astronauts],” Lindsey mentioned. “Our intention is to go to crew finally.”

SNC’s engaged on a bit of the infrastructure for individuals to reside and work in house: An inflatable habitat, which the corporate’s been creating beneath a NASA contract for a number of years. SNC’s habitat design has three flooring however, as a result of it is inflatable, it could possibly be launched on a traditional rocket. The habitat has a wide range of functions, Lindsey famous, akin to a station in orbit or a base on the floor of the Moon. The corporate’s current testing has additionally discovered the inflatable construction to be even stronger than anticipated.

“We simply accomplished testing with a 3rd scale mannequin and we needed to finish the testing as a result of we could not break it,” Lindsey mentioned.

Inflatable habitats have been checked out by different corporations, because of the benefit of launching in a smaller kind issue after which increasing to a bigger quantity as soon as in house. Bigelow Aerospace is well-known for its improvement of inflatable habitats, having linked its BEAM module to the Worldwide House Station in 2016. However Bigelow Aerospace had not launched considered one of its deliberate full dimension habitats earlier than the corporate reportedly closed operations earlier this 12 months.

Lindsey famous that SNC’s construction and technique is totally different than what Bigelow Aerospace was, however the two corporations had labored collectively – as SNC constructed the mechanism that linked BEAM to the ISS.

Along with the inflatable habitat, Lindsey has a complicated improvement group at SNC that he mentioned “is taking a look at by-product Dream Chaser applied sciences and making use of them in different areas.” That staff got here up with a proposal for an orbital outpost that makes use of the Taking pictures Star cargo module – which SNC in July received a contract for from the Pentagon’s Protection Innovation Unit.

“Think about a big, very succesful satellite tv for pc with an enormous quantity of energy, that might optionally be crewed or uncrewed,” Lindsey mentioned.

The SNC VP put it merely: “We’re closely concerned in just about all the pieces that NASA is doing in exploration.” With the U.S. house company largely centered on additional exploration of the Moon, SNC is part of three NASA efforts: The Human Touchdown Methods (HLS) program, the lunar Gateway, and the Industrial Lunar Payload Providers (CLPS) program.

The HLS program is the most important near-term alternative, with NASA seeking to make investments closely in no less than one of many three groups competing to construct a lunar lander that may carry astronauts to-and-from the floor of the Moon. SNC is part of the HLS staff led by Dynetics – an area firm owned by protection contractor Leidos – which is competing with Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin. The three groups received a mixed $967 million earlier this 12 months, with much more profitable awards anticipated in February after a 10 month design research interval.

“We’re additionally concerned in, imagine it or not, constructing a lunar rover with a number of entities,” Lindsey mentioned. “Whereas there hasn’t been a request for proposals … NASA is taking a look at an unpressurized rover that may really carry individuals on the lunar floor – form of an Apollo on steroids.”

Moreover, Lindsey famous that Japan’s house company not too long ago partnered with NASA to supply a pressurized lunar rover – one other proposal SNC is concerned in. 

“We’re working by some partnerships proper now on these two main rovers,” Lindsey mentioned. “We won’t actually discuss an excessive amount of about teammates however … we’ll go pursue that chance.”

Lastly, SNC can be contemplating utilizing its Taking pictures Star cargo module as a pressurized spacecraft that may carry astronauts from Earth’s orbit to the Moon. 

“We will go up with Dream Chaser, simply switch crew right into a free flying cargo module and use that to move individuals,” Lindsey mentioned.

The Dream Chaser spacecraft is on the core of SNC’s imaginative and prescient for infrastructure in house – with the corporate aiming to be part of lots of the areas that trade analysts anticipate will develop shortly within the subsequent decade.
