Sierra Nevada starts installing thermal tiles on Tenacity

June 27, 2020 at 6:05 pm Robert Zimmerman Points of Information

Capitalism in space: Sierra Nevada has received and started to install the thermal protection tiles for its first Dream Chaser reusable mini-shuttle, dubbed Tenacity.

The Thermal Protection System (TPS) tiles are one of the major hardware components used on Dream Chaser and cover nearly the entire craft to protect it from the heat of the sun and the plasma regime during atmospheric reentry. The tiles can withstand the scorching heat of 1,650°C (3,000°F) and prevent the vehicle from being destroyed during reentry.

Dream Chaser has approximately 2,000 TPS tile compared to the 24,000 tiles used on the Space Shuttle. Dream Chaser is about 1/4 the size of a Shuttle Orbiter. The tiles on Dream Chaser utilize a room temperature vulcanizing (RTV) silicone to keep the tiles bonded to the vehicle at all times. The silicone can withstand high temperatures, making it ideal for use. Each of the tiles is tested by a mechanism that pulls on each one, helping avoid issues of the tiles falling off, which happened early in the Space Shuttle Program.

The company notes that the vehicle remains on schedule for a 2021 launch on a ULA Vulcan rocket.

Sierra Nevada names its first Dream Chaser spacecraft “Tenacity”

May 2, 2020 at 7:52 am Robert Zimmerman Points of Information

Capitalism in space: Sierra Nevada yesterday announced that it is giving the name “Tenacity” to its first Dream Chaser spacecraft.

Though the press release does not say so, this decision essentially confirms the company intention to build more Dream Chaser spacecraft, once this one proves itself in flight. And I would expect those later craft will be aimed at manned flight.

Update on Dream Chaser

January 10, 2020 at 9:54 am Robert Zimmerman Points of Information

Link here. According to Sierra Nevada, the company that is building this mini-shuttle cargo ship, they are on track to launch next year. They are also aggressively working on a Dream Chaser version that would be able to transport humans to space.

SNC has “never stopped working” on the crewed version of Dream Chaser, Lindsey said. While the company’s focus right now is getting the cargo version ready for its first flight on a United Launch Alliance (ULA) Vulcan-Centaur rocket next year, the first crewed flight “absolutely” will take place within 5 years.

“There’s interest, not necessarily from NASA, but other customers” that Lindsey expects to grow once the cargo version is flying. SNC will offer either a “taxi model” where it supplies the crew to fly it, or a “rental car model” where the customer provides the crew. It will be up to the customer to decide.

If they can get this spacecraft operational, they will join SpaceX as a leader in the reusability market, having built a ship that can be flown repeatedly on profit-making missions. In fact, it appears that the entire private American effort to get humans into space is aggressively shifting towards full reusability. SpaceX has got the first stage solved, and is also now routinely reusing its cargo Dragon capsules. It is also working to make both the upper stage (Starship) and manned capsules (crew Dragon) reusable. Sierra Nevada is in turn working on the manned spacecraft with Dream Chaser. Similarly, Blue Origin says the first stage of its New Glenn rocket will be reusable.

Those companies and nations that ignore this development (such as the Europeans Space Agency and Russia) will find themselves left far behind. Reusablity of rockets has been proven, and it lowers the cost to get to space so radically that without it you cannot compete.

Sierra Nevada updates Dream Chaser status, names its cargo module

November 20, 2019 at 11:01 am Robert Zimmerman Points of Information

Capitalism in space: In providing a detailed update in the construction of its reusable Dream Chaser mini-shuttle, Sierra Nevada yesterday revealed that it has named the small expendable cargo module that it will be attached to its Dream Chaser “Shooting Star.”

As part of Dream Chaser’s overall design, the vehicle itself does not contain the berthing port or solar arrays needed for it to perform its mission. Instead, those elements are mounted on what had been, before today, referred to as the cargo module – an element of Dream Chaser that now has a dedicated name: Shooting Star.

The name is a nod to the fact that it is the only part of Dream Chaser that is disposable and will burn up in the atmosphere as a streaking ball of fire – just like a shooting star.

The module itself, while containing the solar arrays and main propulsion elements for orbital maneuvering, will also be capable of transporting a large amount of internal cargo to the Station. It is also the part of Dream Chaser on which external cargo can be mounted for delivery and disposal of external elements that are no longer needed for the orbital outpost.

The article provides many details about the status of Dream Chaser that are worth reading, including noting its other potential uses beyond supplying ISS with cargo.

Dream Chaser’s primary structure completed

October 16, 2019 at 9:34 am Robert Zimmerman Points of Information

Capitalism in space: The primary structure for Sierra Nevada’s reusable mini-shuttle, Dream Chaser, has been completed and delivered to the company’s Colorado facility for final assembly.

Essentially, this structure, built by Lockheed Martin, is basically the hull of Dream Chaser. Sierra Nevada now has to install the guts.

They won the contract to build Dream Chaser from NASA in 2016, and for the past three years the company has said little about its progress, causing me concern that there might be issues. This story dispels those concerns.

It is also instructive to compare their progress with SLS, if only to illustrate the advantage of NASA buying what it needs from private companies, who retain ownership of their work, rather than having NASA design and own its hardware.

Dream Chaser: Sierra Nevada first began development of Dream Chaser in 2011, but full construction did not begin until the 2016 contract award. They hope to launch by the end of 2021. This means they will go from award to flight in five years.

The contract’s specific amount was never published, but NASA’s did say that the maximum it would spend for all missions performed by all three cargo capsules (SpaceX, Northrop Grumman, Sierra Nevada) would be $14 billion. This means Sierra Nevada’s share is probably around $4 to $5 billion.

SLS: NASA began its first design work on this heavy lift rocket in 2004, but the first design, dubbed Constellation, was cancelled by President Obama in 2010. Congress then stepped in and mandated that construction continue, under a revised design, now dubbed the Space Launch System. Launch of the first SLS is now expected in 2021.

The cost? Based on my research for my policy paper, Capitalism in Space, the cost by 2021 will be $25 billion.

So, while Sierra Nevada will take five years and $4 to $5 billion to fly its spacecraft, NASA will take eleven years and $25 billion to fly its. I admit the scale is different, but SLS fares as badly when a similar comparison is made with Falcon Heavy.

The difference? Dream Chaser is privately owned, privately designed, and privately managed, by one company, with the goal of making a profit as quickly as possible. SLS is government owned, government designed, and managed by a host of agencies, lawmakers, and contractors, with no set clear goal and no requirement to make a profit at any time.

Schedule for Dragon/Starliner manned flights revised

June 21, 2019 at 9:04 am Robert Zimmerman Points of Information

Capitalism in space: NASA has released a new updated planning schedule for the manned flights of both SpaceX’s Dragon and Boeing’s Starliner manned capsules.

Boeing’s first unmanned demo flight of Starliner is now set for September 17, 2019. This will be followed by SpaceX’s first manned Dragon flight, scheduled for November 15, 2019. Boeing will then follow with its first manned Starliner flight on November 30, 2019.

These are considered target dates. I have great doubts that the Starliner schedule will proceed as described, while SpaceX’s schedule is more likely.

The article also had this interesting tidbit about the upcoming launch schedule of Sierra Nevada’s unmanned reusable cargo ship Dream Chaser:

According to the document, the first flight of Dream Chaser will take place in a planned September 2021 timeframe and will see the vehicle remain berthed to the International Space Station for up to 75 days before returning to Earth to land on a runway for reuse.

There are clearly issues with all these commercial projects. For example, the GAO today released a new report citing the numerous delays in this commercial manned program and calling for NASA to come up with a more complete back-up plan.

Nonetheless, the 2020s have the potential to be the most exciting decade in space exploration since the 1960s. If all goes even close to these plans, the U.S. will have three operating manned spacecraft (Dragon, Starliner, Orion), two reusable cargo spacecraft (Dragon, Dream Chaser), one non-reusable (Cygnus), and a plethora of launch companies putting up payloads of all kinds, from planetary missions to basic commercial satellites numbering in the thousands.

Much could happen to prevent all this. Keep your fingers crossed that nothing will.

NASA approves Dream Chaser design

December 19, 2018 at 9:04 am Robert Zimmerman Points of Information

Capitalism in space? Sierra Nevada has, after several years of work, obtained NASA’s approval of the design of its Dream Chaser mini-shuttle, and will now begin construction.

I put a question mark in the header above because I am no longer sure Sierra Nevada is building a privately designed and privately owned spacecraft for the launch market. It seems that they have been captured entirely by NASA, and will instead be building the spacecraft NASA wants, which might raise costs enough to make this vehicle unaffordable for other customers.

The situation is understandable. Sierra Nevada does not have the independent capital that gives SpaceX its independence. It needs NASA to get this ship built, and thus will do whatever NASA demands. I just worry that NASA, unconcerned about cost (as is every agency in the federal government today), will spoil Dream Chaser’s viability in the commercial market.

Sierra Nevada opens all rockets to launching Dream Chaser

April 19, 2018 at 9:33 am Robert Zimmerman Points of Information

In a status update for its Dream Chaser reusable mini-shuttle cargo ship to ISS, Sierra Nevada officials also revealed that they are considering a wide range of launch companies for future launches.

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.”

Their willingness to open up the launch bidding is merely a recognition that they can save money by encouraging competition for their business. The vehicle itself has not yet completed its design review, though they hope to begin its assembly within a month, with a planned launch date in late 2020.

The company was awarded its cargo contract in January 2016, more than two years ago. It seems to me that it has taken far too long to get to this point. I wonder if NASA has thrown up roadblocks, as it has with SpaceX.

NASA approves 2020 launch window for first Dream Chaser flight

February 9, 2018 at 8:32 am Robert Zimmerman Points of Information

Capitalism in space: Sierra Nevada has gotten the okay from NASA to aim for a 2020 launch window for the first flight of its reusable Dream Chaser mini-shuttle.

SNC announced Feb. 7 that it had received “authority to proceed” on that mission using the company’s Dream Chaser vehicle. The mission will launch on a United Launch Alliance Atlas 5 rocket in late 2020. The mission is the first of six in the company’s Commercial Resupply Services (CRS) 2 contract it won in 2016 to transport cargo to and from the ISS. SNC received a CRS-2 contract along with current CRS providers Orbital ATK and SpaceX.

“While we won the contract a couple of years ago, the contract still needed to be validated by a task order,” said Mark Sirangelo, executive vice president of SNC’s Space Systems business area, in a Feb. 7 speech at the Federal Aviation Administration’s Commercial Space Transportation Conference here. That order, he said, is the “biggest step” to date on the program. That flight will be a “full scale, fully operational mission,” he said, even though it will represent the first orbital flight of the Dream Chaser. Orbital ATK and SpaceX, who developed their Cygnus and Dragon spacecraft, respectively, under earlier NASA Space Act Agreements, flew demonstration missions before starting their operational CRS cargo flights.

Do not be surprised if this flight does not launch on schedule. I fully expect that development will push it back into 2021, a delay that would not be unreasonable.

Capitalism in space: Sierra Nevada’s Dream Chaser test vehicle today completed its second glide test, the first since 2013, successfully gliding to a perfect landing after being dropped from a helicopter at an altitude of 10,000 feet.

Unlike the 2013 glide test, the landing gear worked perfectly. With two such tests under their belt, the company I think has demonstrated that the spacecraft will be able to execute a landing. Next comes the building and test flight of the actual spacecraft.

Sierra Nevada and Canada sign agreement for using Dream Chaser

October 3, 2017 at 3:11 pm Robert Zimmerman Points of Information

Capitalism in space: Sierra Nevada has signed an agreement with the Canadian Space Agency (CSA) to study ways in which Canada might utilize the company’s reusable Dream Chaser spacecraft.

This agreement is very preliminary, with no apparent specific plans announced nor any exchange of money. It is however another signal of the strong interest that foreign governments have in buying time on Dream Chaser, once it is operational.

Capitalism in space: Sierra Nevada and the German Aerospace Center have signed a new agreement increasing their partnership for using Dream Chaser in space.

The current MOU follows a 2013 Technical Understanding between the parties that initiated cooperation on space activities. This new agreement allows the two entities to establish goals and baseline objectives on future missions, scientific contributions and future space architecture for LEO, Cislunar and lunar operations, and deep space exploration.

It is clear once again that Sierra Nevada is trying to find partners who can pay to keep Dream Chaser flying as much as possible, between its cargo missions to ISS.

UN announces proposed Dream Chaser international mission

September 27, 2017 at 10:15 am Robert Zimmerman Points of Information

Capitalism in space: The Outer Space office of the United Nations has announced an opportunity for member nations to express their interest in doing a science mission using Sierra Nevada’s Dream Chaser reusable spaceship.

The UN announcement states that

The purpose of this Call for Interest (CFI) is to provide a summary of the proposed mission and to solicit information from Member States interested in providing experiments, payloads, or satellites that could be flown on this mission. The CFI also has the objective of gathering information on the interested countries so that UNOOSA may better understand the demand for this type of mission.

The actual call [pdf] roughly describes a mission lasting 2 to 3 weeks and carrying about 20 experiments. This call is designed to give them a better idea of what those experiments might be, what nations wish to participate, and where the funding for the mission might come from. The actual announcement to submit experiment proposals won’t come until March 2018.

Being a UN mission, it is not surprising that it wants to focus on a variety of leftwing “Sustainable Development Goals”:

Dream Chaser test vehicle undergoing tow tests

July 17, 2017 at 8:58 pm Robert Zimmerman Points of Information

Capitalism in space: Sierra Nevada’s Dream Chaser engineering test vehicle underwent tow tests today.

Rolling on two main landing gear wheels and a nose skid, the Dream Chaser traveled down a runway Monday in Sierra Nevada’s latest tow test at Edwards Air Force Base, which is co-located with NASA’s Armstrong Flight Research Center. Once cut free from its tow vehicle, the Dream Chaser slowed to a stop, allowing engineers to gather data on the craft’s brakes, steering system, and guidance, navigation and control sensors that will line the spaceplane up for landing, according to Eric Cain, a Sierra Nevada engineer who described Monday’s test on the company’s Twitter account.

More tests are planned in the coming months, including additional tow tests and a “captive carry” flight with the Dream Chaser suspended under a helicopter.

This is the same engineering test vehicle that underwent tow tests and flew successfully once, though its landing gear failed up upon touchdown. They have replaced that landing gear, which was borrowed from the Air Force and was never intended to be the spacecraft’s wheels. Thus, they need to go through these tests all over.

Dream Chaser flight tests upcoming

March 6, 2017 at 10:40 pm Robert Zimmerman Points of Information

The competition heats up: According to Sierra Nevada officials, drop tests and glide tests of the engineering test ship of its Dream Chaser cargo spacecraft will begin this spring.

The partially-assembled test craft arrived at the California test site, located on Edwards Air Force Base, on Jan. 25. Technicians are adding the ship’s V-shaped tail fins and other equipment before kicking off ground and flight tests in the coming months, according to Mark Sirangelo, corporate vice president of Sierra Nevada’s space systems division. “We’ll do a series of ground tests,” Sirangelo said in a recent interview. “That will include towing the vehicle down the runway, and that allows us to see how it stops and how it moves, but it also allows us to test all the sensors on the vehicle because we can get it up to a high enough speed where that will happen.”

…After the ground tests, Sirangelo said the Dream Chaser test article will perform “captive carry” tests suspended under a helicopter, using the exercises to verify the movements of the craft’s aerosurfaces and navigation instrumentation. “When that’s done, we’ll move into a series of flight tests, where it will be dropped for approach and landing like the shuttle Enterprise,” Sirangelo said, referring to the vehicle NASA used for landing demonstrations in the 1970s before the first full-up space shuttle mission.

This all sounds great, but Sierra Nevada has been promising these test flights now for more than a year. It is time they got started already.

Using the X-37B as a space ambulance?

November 8, 2016 at 10:16 am Robert Zimmerman Points of Information

Researchers have proposed using the Air Force’s X-37B as an ambulance in space.

Halberg said that an effective astronaut taxi should, among other things, be able to stay at the ISS for two years or more at a stretch; be capable of getting people back to Earth rapidly, within three hours or so; impose minimal G-loads on occupants; have the ability to land close to a hospital; and allow patients to lie in a supine position. These requirements all point to a space plane rather than a capsule, Halberg said — meaning SpaceX’s Dragon capsule and Boeing’s CST-100 capsule, which are scheduled to start flying NASA astronauts to and from the ISS within the next year or two, wouldn’t make the grade as ambulances.

Another private crew-carrying vehicle that’s currently in development, Sierra Nevada Corp.’s Dream Chaser space plane, is an intriguing option that bears further investigation, Robinson and Halberg said. But their initial concept study focused on the robotic X-37B, chiefly because the 29-foot-long (8.8 meters) military space plane has already racked up millions of miles in orbit, while Dream Chaser has yet to launch.

Makes sense, though once Dream Chaser is flying it will have the potential to provide the same service with far greater capabilities.

Dream Chaser to fly 14-day UN mission in 2021

September 28, 2016 at 9:05 am Robert Zimmerman Points of Information

The competition heats up: Sierra Nevada today signed a deal with the United Nations to fly a 14-day mission in 2021 using Dream Chaser.

The first-ever United Nations space mission is intended to launch in 2021 and will allow United Nations Member States to participate in a 14-day flight to low-Earth orbit (LEO) on SNC’s Dream Chaser spacecraft. “One of UNOOSA’s core responsibilities is to promote international cooperation in the peaceful use of outer space,” said Simonetta Di Pippo, director of UNOOSA. “I am proud to say that one of the ways UNOOSA will achieve this, in cooperation with our partner SNC, is by dedicating an entire microgravity mission to United Nations Member States, many of which do not have the infrastructure or financial backing to have a standalone space program.”

According to Ms. Di Pippo, funding of the mission will come from multiple sources. “We will continue to work closely with SNC to define the parameters of this mission which, in turn, will provide United Nations Member States with the ability to access space in a cost-effective and collaborative manner within a few short years. The possibilities are endless.” Countries selected to provide mission payloads will be asked to pay a pro-rated portion of the mission cost, based on the resources required to host the payload and their ability to pay. In addition, major sponsors are being sought to finance a large portion of the mission costs.

While the press today is in a feeding frenzy writing stories about Elon Musk’s speech, they are ignoring this story. Yet, this deal between the UN and Sierra Nevada is actually far more important. Musk’s proposals, while exciting and important in how they move the conversation of space exploration forward, are mostly Powerpoint fantasies. He does not have customers for his interplanetary transportation system. He does not have a rocket. All he has is the Raptor engine, which is only beginning its design testing. It will be years before any of his proposals here become real.

This UN/Sierra Nevada deal however is reality. A private American company is building a spaceship that it is now selling successfully to third world nations. Actual money will change hands. Profit will be earned. And Sierra Nevada will be in a position to use those earnings to upgrade and advance its designs. This will be the future, far sooner than Elon Musk’s International Transportation System.

Sierra Nevada preps for Dream Chaser glide tests

July 29, 2016 at 8:31 am Robert Zimmerman Points of Information

The competition heats up: In preparing its Dream Chaser engineering test vehicle for glide tests in California this fall, Sierra Nevada unveiled it to the press yesterday.

This is essentially the test vehicle’s first public viewing since its one glide test, when the front landing gear did not deploy correctly and the vehicle was damaged during landing. Since the landing gears were not the gears being developed for the flight craft, and since the glide test itself went well, both the company and NASA considered that glide test to be a success.

It has now been refurbished for new tests in conjunction with the company’s contract to use Dream Chaser as a cargo ship for NASA.

Sierra Nevada completes first Dream Chaser milestone

July 12, 2016 at 7:56 am Robert Zimmerman Points of Information

The competition heats up: Even as it prepares to complete the last milestone in its NASA contract for developing a manned version of Dream Chaser, Sierra Nevada has just completed the first milestone on its contract to build a cargo version of the reusable lifting body spaceplane.

Though Sierra Nevada did not win a contract to build the manned Dream Chaser, it did have a development contract with NASA that called for one more glide flight test, a test the company had until now decided not to fly because the cost would exceed the milestone payment. This changed however after they won a cargo contract, as the flight will provide important test data for building the cargo version.

Meanwhile, the company’s plan for building the cargo vehicle has been approved by NASA, thus rewarding them their first milestone on that contract, with the following schedule:

Per current schedule goals, Mr. Olson added the inaugural Dream Chaser cargo flight to ISS is aiming for a launch – on the United Launch Alliance Atlas V – as early as October 2019, or as late as April 2020. The company is aiming to build two Dream Chasers, able to fly a total of 30 times over a 10 year lifetime.

Once built and successfully flying, they also plan to move forward on developing the manned version, both for NASA and for others.

Sierra Nevada signs deal with UN

June 29, 2016 at 9:29 am Robert Zimmerman Points of Information

The competition heats up: Sierra Nevada has signed a memorandum of understanding with the United Nations, creating the framework for UN member nations to use its Dream Chaser cargo vehicle for science research.

Under the agreement, [Sierra Nevada] committed to dedicating one or more Dream Chaser missions that will host payloads from member countries. The cooperation will focus on developing an interface control document and payload hosting guide to allow payloads developed by participating countries, especially non-space-faring ones, to be flown into orbit.

What this means is that American space technology, developed and owned privately rather than built by NASA, is beginning to grab business wherever it can find it. These UN space missions eventually flown on Dream Chaser might be foreign built, but it will be the American spacecraft that gets them to space..Sierra Nevada will not only make money doing so, it will position itself financially to develop even better space products that it can sell worldwide. Nor will Sierra Nevada be alone in this. The result will be the increasing prosperity of the American aerospace industry as it gains a larger share in the settlement of the solar system.

Sierra Nevada prepares for Dream Chaser glide tests

June 23, 2016 at 9:46 am Robert Zimmerman Points of Information

The competition heats up: Sierra Nevada now expects to deliver its refurbished engineering test prototype of Dream Chaser to NASA for new glide tests in August.

“Our version of the shuttle Enterprise is about to be finished for its next phase of flight tests,” [said Mark Sirangelo, corporate vice president.] “Somewhere in the August time frame, it’s going to be shipped off to California, to the Armstrong [Flight Research] Center and to Edwards to be in Phase 2 of flight testing, which is going to be really fun and exciting.”

Sirangelo said lessons learned from the atmospheric flight tests will be applied to the development of the orbital test vehicle, which is now being outfitted in Colorado. That test vehicle, in turn, will blaze the trail for the spacecraft that will carry cargo for NASA under the CRS-2 contract. “We are looking to be launching on time, which is about three years from now, in the second half of 2019,” Sirangelo said.

They get this cargo version flying successfully, and they will certainly get a contract to build a manned version.

The competition heats up: At a workshop in Alabama this week Sierra Nevada’s vice president indicated that though the company has not yet finalized its decision, it is strongly leaning to picking Huntsville as the commercial spaceport for its Dream Chaser mini-shuttle, being built to ferry cargo to ISS.

“There was a leap of faith on the Huntsville side that we would be a company that could get this vehicle built and start servicing the space station…,” Sierra Nevada Vice President John Roth said Thursday. “Yes, we have been approached by other airports for ventures. We’re not moving forward at this time with any of those. Right now, Huntsville is the only community we’re moving forward with a (landing) license on.”

A preliminary local study identified four hurdles to landing Dream Chaser at the Huntsville International Airport: required licenses for the craft and airport, environmental impact approval, Federal Aviation Administration approval of the landing path and possible runway damage.

Why do I sense the unseen hand of porkmeister Senator Richard Shelby (R-Alabama) in this story? Could it be that one of the reasons NASA finally included Dream Chaser in its cargo contract was that the company had not only chosen the Alabama-based Atlas 5 rocket for its launch vehicle but was also courting Alabama for its commercial base, and Shelby had made it clear behind the scenes that he wanted that business? Could it be that Sierra Nevada is now returning the favor, having gotten the contract?

Don’t get me wrong. I think it was a good choice for NASA to give that contract to Sierra Nevada. I just think it important to note how giving some of our power away to politicians allows them to wield that power over us, sometimes to our benefit, sometimes against it, but always to make themselves more powerful. In the end, giving that power away is never a good option.
