Sierra Space confirms its Tenacity spacecraft successfully completed vibration testing

9:16 am

Sierra Space yesterday confirmed that its first Dream Chaser reusable mini-shuttle Tenacity, being readied for a hoped-for April launch, successfully completed vibration testing last month.

Key accomplishments in this first critical phase of pre-flight testing included: the completion of Sine Vibration Testing (in all three axes or directions), a Separation Shock Test that simulates the separation of the Dream Chaser from Shooting Star and a test that involved deploying the spaceplane’s wings. These tests evaluated Dream Chaser’s performance under the stresses of launch, operation in orbit and ability to communicate with the International Space Station (ISS).

What I find revealing about the press release at the link is that it really adds nothing from a NASA press release from a month ago. Then NASA said that Tenacity was about to move to a vacuum chamber for environmental testing. According to this new press release, that move has still not occurred and the environmental test still must begin.

That engineers didn’t move Tenacity to environmental testing while they were reviewing the vibration test data suggests there was something in that test data that prevented it. It appears that unstated issue is resolved, but it caused a pause in testing.

As a result, it appears that an April launch is unlikely delayed by a month or more, assuming my attempt to read between the lines is correct.

Vibration testing of Sierra Space’s Tenacity mini-shuttle completed

9:01 am

NASA engineers have now completed vibration testing of Sierra Space’s Tenacity mini-shuttle, set to launch on a Vulcan rocket later this year.

Reading between the blather in the NASA press release at the link, it appears that testing was successful, proving that the Dream Chaser spacecraft can survive the vibrations of launch. This conclusion by me however remains unconfirmed. Engineers are now preparing the mini-shuttle for environmental testing.

Next up, Dream Chaser will move to a huge, in-ground vacuum chamber that will continue to simulate the space environment Dream Chaser will encounter on its mission. The spaceplane will be put through its paces, experiencing low ambient pressures, low-background temperatures, and dynamic solar heating.

Previously the launch date had been targeting April 2024, according to ULA officials. It now appears, from the vagueness of recent reports, as well as the actual testing now in progress, that the launch date has slipped. They appear to be targeting the first half of 2024, but are as yet unwilling to commit to a date.

NASA: The flight plan for Dream Chaser Tenacity’s first demo mission to ISS

9:30 am

NASA today provided a detailed description of the flight plan for the first demo ISS mission of Sierra Space’s first Dream Chaser reuseable mini-shuttle, dubbed Tenacity, now targeting some unspecified date in 2024.

It will carefully approach ISS, testing its maneuvering and rendezvous capibilities, and then be grabbed by the station’s robot arm to be berthed to the station.

On its first flight to the International Space Station, Dream Chaser is scheduled to deliver over 7,800 pounds of cargo. On future missions, Dream Chaser is being designed to stay attached to the station for up to 75 days and deliver as much as 11,500 pounds of cargo. Cargo can be loaded onto the spacecraft as late as 24 hours prior to launch. Dream Chaser can return over 3,500 pounds of cargo and experiment samples to Earth, while over 8,700 pounds of trash can be disposed of during reentry using its cargo module.

On this first demo flight it will remain docked for 45 days, and then land on the shuttle runway at Cape Canaveral.

Sierra Space shakes up its staffing

8:44 am

Sierra Space yesterday did a major staffing shake up, laying off 165 workers while shifting 150 with secruity clearances from its parent company Sierra Nevada.

Sierra Space this week shipped the first Dream Chaser, named Tenacity, for pre-launch testing at NASA’s Armstrong facility in Ohio. The layoffs began soon after, the Sierra Space spokesperson said, noting the company conducted a surge in hiring this year to complete work on the Tenacity spacecraft.

With Tenacity shipped, Sierra Space’s spokesperson said the company is realigning to focus on the operations phase of Dream Chaser’s first mission, as well as on classified national security work. The latter part of Sierra Space’s realignment includes adding nearly 150 employees with security clearances from Sierra Nevada Corp., the aerospace and defense contractor owned by Fatih and Eren Ozmen, which the space company was spun out of two years ago. Sierra Space’s spokesperson said the company is creating a national security space team to work on several classified contracts.

This shift suggests that at least in the short run, Sierra is putting more focus on future military contracts rather than its civilian manned space projects like its LIFE space module (for the Orbital Reef space station) and future manner versions of its Dream Chaser mini-shuttle. I wonder if the company is having more internal doubts about Orbital Reef and its main partner, Blue Origin. Unlike the stations being built by Axiom and Voyager Space, which have already garnered contracts from both national and international customers, Orbital Reef has not done the same. There could be great doubts in the space community it will be built because of Blue Origin’s absymal record for building anything.

Sierra Space: Tenacity is complete and ready for ground testing

9:50 am

Sierra Space announced yesterday that its reuseable Tenacity cargo freighter, the first of its Dream Chaser mini-shuttles, is now complete and ready shipment to NASA’s test facilities in Ohio for ground testing.

The spacecraft hopefully will fly next year. Though this is four years behind schedule, it signals an important milestone for the company, and suggests its operational pace will pick up afterward. Though its arrival comes very late in ISS’s lifespan, the coming arrival of many private space stations, including Sierra’s own, will likely provide it many customers.

Sierra Space raises another $290 million in private investment capital

2:26 pm

Sierra Space today announced that during its most recent funding round it successfully raised another $290 million in private investment capital, bringing the total capital it has raised to $1.7 billion.

The round is co-led by Japan’s largest bank, MUFG, Kanematsu Corporation, a Japanese trading company and Tokio Marine & Nichido Fire Insurance, Japan’s largest property and casualty insurance group with participation from Sierra Space’s existing investors. The companies are already participating in a JAXA (Japanese Aerospace Exploration Agency) study to explore how to conduct activities in LEO as the ISS approaches the end of service.

These Japanese partnerships act to strengthen Sierra’s already strong links to Japan, including ongoing negotiations to land its Dream Chaser reusable mini-shuttes at Oita Airport, as well as partnership deals with Kanematsu, Japan Airlines and Mitsubishi.

This successful fund-raising round suggests strongly that the company’s plans to finally have its first Dream Chaser cargo shuttle, Tenacity, ready to fly in December might actually happen. Or at least, that plan acted to convince these investors to pony up some cash.

Sierra Space says first Dream Chaser will be ready for launch by December

12:41 pm

In a presentation at an investor conference on June 27, 2023, a Sierra Space official provided an update on the status of its first Dream Chaser reusable mini-shuttle, dubbed Tenacity, stating that they expect it to be ready for launch by December, with the main question whether its ULA Vulcan launch rocket will also be ready.

The launch is supposed to be the second for Vulcan, but the first launch was just delayed for an undetermined amount of time so ULA can make modifications to the rocket’s Centaur upper stage. Once Tenacity is flying Sierra has a contract with NASA for seven cargo flights to ISS, with plans beyond.

The company is also working on a second version that can carry both crew and cargo. Vice said that version will have 40% greater cargo capacity than the first version and can support a six-person crew.

The ability of Dream Chaser to glide back to Earth in a runway landing, rather than splash down in the ocean, is a key selling point to customers, he argued. “We just think that landing at runways around the world is a huge differentiator: low-g landing back on a runway for both time-critical cargo and science, but also just the way people are going to want to fly back and land.”

The official also indicated that this human-rated version is being designed to work with the private Orbital Reef space station that Sierra Space is building in partnership with other companies. The company also said it is planning its own free flying version of its Orbital Reef LIFE module that the company hopes to launch by the end of 2026, ahead of Orbital Reef. If so, that would make this the sixth independent private space station planned by American companies.

Because much of this presentation was designed to impress potential investors, we should take it with a touch of skepticism. Nonetheless, that the company is considering launching its own station, independent of the Blue Origin-led Orbital Reef station, suggests it has its own doubts about whether that project will ever take off as planned, and has thus decided to make its own contingency plans.

Sierra Space powers up its Dream Chaser mini-shuttle for the first time

9:09 am

Sierra Space yesterday announced that it has successfully run electricity for the first time through its first Dream Chaser mini-shuttle, dubbed Tenacity.

The press release is remarkably lacking in detailed information, or graphics. This quote is really the only hard facts mentioned:

Sierra Space simulated the power that will be generated from Dream Chaser’s solar arrays once on orbit. Test engineers plugged that power into Dream Chaser and began turning on systems. Sierra Space exercised flight computers, base processors and low-voltage distribution units.

Tenacity has been under construction since 2016, when the company won its NASA contract to build it. That’s seven years to build a single spacecraft, and yet all they have done so far is feed electricity through it for the first time. In that time period SpaceX not only built multiple prototypes of Starship and Superheavy, it has flown multiple test flights.

Is money an issue? The actual contract amount NASA gave Sierra Space to build Tenacity has never been published, though NASA has said the total awarded for all the cargo missions to be flown by SpaceX, Northrop Grumman, and Sierra Space equaled $14 billion. Since these fixed price contracts also require the companies also commit some of their own funds, or obtain outside financing, it is possible that Sierra Space has had money issues slowing development.

Regardless, Dream Chaser was first supposed to fly in 2020. It is now three years late, with no clear indication that a launch will come anytime soon. In many way, Sierra Space is beginning to remind me of Blue Origin, endlessly issuing promises but never delivering.

Launch of Sierra Space’s Dream Chaser now scheduled for six month window opening in August

9:47 am

After years of delays, Sierra Space’s first Dream Chaser reusable mini-shuttle, dubbed Tenacity, is now scheduled for launch during the six month mission to ISS of a crew scheduled for launch in August.

Dream Chaser’s first flight on a United Launch Alliance Atlas V rocket is expected while Crew-7 is aboard and two of those crew members, NASA’s Jasmin Moghbeli and JAXA’s Satoshi Furukawa, recently trained on it. JAXA and NASA formally announced Furukawa’s assignment to Crew-7 today. Furukawa, Moghbeli, ESA’s Andreas Mogensen and a Russian cosmonaut whose assignment has not been officially announced yet, are expected to launch in mid-August for a 6-month stay on the ISS.

The exact launch date within that mission has not yet been determined. It will largely depend scheduling, fitting it in with other launches to the station, assuming Tenacity’s construction is finished in time. That construction began in 2015, and has taken three to four years longer than first announced.

  • Sierra Space: Mission: Tenacity Part 1

    • This video is just an empty-of-content commercial for Sierra Space, filled with feel-good “woke” blather but little real information about the actual status of this long overdue spacecraft. It is worth watching however because it reveals this emptiness. Reminds me of the many similar videos from Blue Origin and NASA over the years, filled with big promises but little actual achievement.

  • How does Starlink Satellite Internet Work?

    • This video, almost 30 minutes long, is definitely worth watching if you have any interest in signing up for Starlink, or just have an interest in the coming low orbit satellite constellation boom.

Thanks to BtB’s stringer Jay.

That’s nice, but years have passed and the first Dream Chaser cargo spacecraft, Tenacity, has still not flown. It is well past time for this company to finally get off the ground.

This also be the first spacewalk using the airlock on the space station’s new Wentian module.

It appears to be built by the pseudo-company Orienspace.

Sierra Space signs partnership deal with Turkey

10:15 am

Sierra Space and ESEN (another affiliated company of Sierra Space’s mother company Sierra Nevada) have signed a partnership agreement with the Turkish Space Agency to work together over the next five years in developing Sierra Space’s Dream Chaser spacecraft and its LIFE orbital space station.

Though the agreement mentions how the three will work together to develop both Dream Chaser and LIFE, because of State department security regulations Sierra Space must be very careful about what technology it reveals to Turkey. I therefore expect the heart of the agreement are these two bullet points from the press release:

  • Space environment utilization on-orbit in LEO, including use of Sierra Space’s Large Integrated Flexible Environment (LIFE) space habitat module
  • Sending payloads to low Earth orbit (LEO) and the moon

Turkey wants to launch its own planetary probes as well as astronauts in order to compete with its Middle East neighbor the UAE. It has thus decided to pay Sierra Space to help it do that. The company can use the cargo Dream Chaser to lift smallsat payloads into orbit, and later use the manned version to lift Turkish astronauts to the LIFE station.

Sierra Space developing crewed version of Dream Chaser; will train astronauts

9:24 am

Capitalism in space: In a press release mostly focused on touting the company’s new project to establish a training center for astronauts, Sierra Space dropped this bigger story:

A crewed variant of the Dream Chaser spaceplane is currently in development and will be operational in 2026, having successfully completed its System Requirements Review (SRR) earlier this month. Orbital Reef will be on orbit and operational in 2027.

Though it was always expected that the company would upgrade the cargo version of Dream Chaser it is presently building, until now it had been made no announcement to that effect. Moreover, until now Sierra Space has functioned much like the old big space companies, doing nothing without a contract from NASA. This effort to build a manned version of Dream Chaser is apparently occurring without any such contract. All Sierra has right now is a contract to launch cargo to ISS.

The astronaut training center fits in nicely with this new manned Dream Chaser, which also fits in nicely with Sierra Space’s partnership to build the commercial space station Orbital Reef.

FAA approves Huntsville airport as landing site for Dream Chaser

9:24 am

Capitalism in space: The FAA announced on May 13, 2022 that it has approved use of Huntsville International airport for landing Sierra Space’s reusable Dream Chaser cargo mini-shuttle, once it begins flying.

The approval covers “up to eight reentry operations at the airport from 2023 to 2027.” Though Sierra Space will still need to get its launch license from the FAA before those flights can happen, it looks like the company is finally getting close to the first flight of Tenacity, its first Dream Chaser ship.

Update on Dream Chaser

10:57 am

Link here.

Overall progress has been incredibly slow, considering the NASA contract to build this was awarded in 2016. Sierra Space is only building one spacecraft, designed to be reusable. For six years to have passed and the spacecraft, dubbed Tenacity, is still a year away from flight, seems excessive, especially because the spaceplane is small. It took SpaceX only four years to go from concept to successfully landing first stages. Starship began test flights only three years after the project began.

Still, the spaceplane is moving forward. Hopefully by February ’23 it will finally fly, giving the U.S. another method besides Dragon for getting cargo to and from space. That it might do so before Boeing’s Starliner is somewhat ironic, and puts more pressure on that company to get that capsule operational.

Sierra Space raises $1.4 billion in investment capital

9:28 am

Capitalism in space: Sierra Space, the space subsidiary of Sierra Nevada, has raised $1.4 billion in investment capital in a recent round of fund-raising.

The company will use the funds to support development of Dream Chaser, the lifting-body vehicle it is building for to transport cargo for the International Space Station starting in late 2022. The company originally developed Dream Chaser to carry people as a competitor in NASA’s commercial crew program, and company executives have frequently stated they still plan to develop a crewed version at a later date.

The funds will also support development of its Large Integrated Flexible Environment (LIFE) inflatable module. Both LIFE and Dream Chaser are part of Orbital Reef, the commercial space station concept announced Oct. 25 by a team that includes Sierra Space along with Blue Origin, Boeing and Redwire.

It appears that the investment community likes the Orbital Reef commercial space station concept, and especially likes Sierra Space’s part in it. This influx of cash also suggests that the investors got a good look at the status of Dream Chaser, and were satisfied its development was proceeding as planned.

Sierra Space teams up with Blue Origin to build its Life space station

10:45 am

Proposed Orbital Reef space station

Capitalism in space: Sierra Space and Blue Origin today announced [pdf] that they are forming a consortium of space companies to build a space station they dub Orbital Reef. From the press release:

The Orbital Reef team of experts brings proven capabilities and new visions to provide key elements and services, including unique experience from building and operating the International Space Station:

  • Blue Origin – Utility systems, large-diameter core modules, and reusable heavy-lift New Glenn launch system.
  • Sierra Space – Large Integrated Flexible Environment (LIFE) module, node module, and runway-landing Dream Chaser spaceplane for crew and cargo transportation, capable of landing on runways worldwide.
  • Boeing – Science module, station operations, maintenance engineering, and Starliner crew spacecraft.
  • Redwire Space – Microgravity research, development, and manufacturing; payload operations and deployable structures.
  • Genesis Engineering Solutions – Single Person Spacecraft for routine operations and tourist excursions.
  • Arizona State University – Leads a global consortium of universities providing research advisory services and public outreach.

I suspect that this deal is actually telling us that Jeff Bezos is spreading some of his Blue Origin money to help finance Sierra Space’s work. The deal also appears to be an effort to generate work for Blue Origin’s not-yet-launched New Glenn rocket and Boeing’s not-yet launched Starliner capsule.

The release says nothing about target dates, but the overview [pdf] on the Orbital Reef website says they are aiming for the second half of this decade.

While the success of such a project can only increase the competition and lower the cost to orbit, thus making the settlement of space more likely, this announcement reeks of the same kind of high-minded promises that came with Blue Origin’s Blue Moon lunar lander: Big plans by the best and most established space companies, with little firm commitment by these companies to actually build anything.

Compared to the Blue Moon lunar lander project, however, this project has one very significant difference that could make it real. Orbital Reef is not being touted in order to win a government contract. It is being touted as a commercial station for private customers. Such a project will require these companies to either invest their own money, or obtain outside investment capital, to build it. To make money they can’t sit and wait for their customers to pay for it, since customers never do that (except the government). They need to first build it.

Meanwhile, the BE-4 engine is not yet flight worthy, so that Blue Origin’s New Glenn rocket remains no closer to launch, even though it is now approaching two years behind schedule.

Sierra Space makes deal with UK spaceport for Dream Chaser landings

9:05 am

Capitalism in space: Sierra Space has signed an agreement with a spaceport in Cornwall, England, allowing it to land its Dream Chaser mini-shuttles there.

Sierra Space signed a memorandum of understanding (MOU) with Spaceport Cornwall expressing support for future landings of Dream Chaser at the spaceport, also known as Cornwall Newquay Airport in southwestern England.

The MOU came after Sierra Space performed a study, supported by the U.K. Space Agency, evaluating the feasibility of using the spaceport for Dream Chaser landings. The lifting body vehicle is designed to glide to a landing on runways, and the initial study concluded the spaceport is “a suitable and viable return location for the orbital return” for Dream Chaser, Sierra Space said in a statement.

The more places Sierra can land Dream Chaser the more commercially viable it will be. For Cornwall, this strengthens its position as a spaceport, having already signed an agreement with Virgin Orbit to allow it to launch from there.

Sierra Nevada gets clearance to land Dream Chaser in Florida

4:58 pm

Capitalism in space: Sierra Nevada today announced that it has now gotten clearance to land its Dream Chaser-class Tenacity spacecraft at the Kennedy Space Center, with a hoped-for first flight in ’22.

The Use Agreement makes SNC the first commercial user of Space Florida’s FAA Re-entry Site Operator License and provides the runway and support facilities needed during testing and landing. It also takes SNC one step further in applying for its own FAA re-entry license, something needed ahead of the first Dream Chaser mission next year.

Because Tenacity is a cargo freighter only, they do not plan a significant test program prior to that first launch to ISS.

Sierra Nevada to make its space operations a separate company

10:01 am

Capitalism in space: Sierra Nevada has decided to spin off its space operations involving Dream Chaser and its proposed private space station into a separate company called Sierra Space.

In a message to employees April 14, SNC [Sierra Nevada] Chairwoman and President Eren Ozmen said the company’s Space Systems division will become a standalone company, called Sierra Space, although remain a subsidiary of SNC.

…Ozmen provided few details about how the transition of SNC’s space business to Sierra Space would unfold, but she said it would take several months to complete. Even after the transition, Sierra Space will “continue deep cooperation and synergy” with SNC’s other business areas in aviation and defense.

My guess is that Ozmen does not want the risks of its space-related projects to impact its more reliable aviation and defense holdings. By separating it out, she can better isolate the success or failure of each. This does not necessarily mean that the space holdings are failing, only that they carry a greater financial risk.

Sierra Space’s future strongly hinges on the success of the first Dream Chaser cargo shuttle, Tenacity, whose inaugural flight has been delayed from ’21 to ’22. If that fails, all the other plans of this space division will likely fail as well. If it succeeds however the company’s financial future will be quite promising.

Sierra Nevada will build space stations and a manned version of Dream Chaser

Sierra Nevada's proposed LIFE space station
Artist conception of Sierra Nevada’s LIFE space station

Capitalism in space: Sierra Nevada announced today that it will not only build a manned version of its Dream Chaser reusable mini-shuttle, it now intends to use that shuttle as a ferry to its own space station, made up of inflatable modules.

They have dubbed their proposed station LIFE, and describe as follows:

The LIFE habitat is a three story, 27-foot large inflatable fabric environment that launches on a conventional rocket and inflates on-orbit. The LIFE habitat is undergoing a NASA soft-goods certification this year and the full size ground prototype developed under NASA’s NextSTEP-2 contract is in the process of being transferred from Johnson Space Center in Texas to Kennedy Space Center in Florida for further testing on short-and long-term habitation. SNC’s Astro Garden® system also provides fresh food within the habitat.

Making a manned version of Dream Chaser was always expected. Adding the company’s own station makes complete sense. Except for the rocket to launch a Dream Chaser spacecraft, Sierra Nevada will be able to provide a full service experience to, in, and from space.

Dream Chaser first flight delayed to ’22

3:44 pm

Officials from Sierra Nevada today revealed they have now delayed the first flight of their mini-reusable Dream Chaser shuttle Tenacity until ’22 rather than late this year.

They claim the cause of the delay is the Wuhan flu.

Sierra Nevada has not announced when in 2022 Dream Chaser will attempt to make its first flight, but Lindsey described how pandemic restrictions prevented engineers from being on site for structural testing of the cargo model. Instead, engineers remotely oversaw the tests from a mission control center in Colorado. While the workaround allowed testing to continue, it took three or four times as long as it should have, Lindsey said.

Other delays came from supplier shutdowns due to COVID-19 outbreaks. Technical challenges not related to the pandemic also caused problems, though Lindsey did not elaborate. “All of those things have conspired to move the date a little bit,” Lindsey said.

The first issue is a management decision by the company. I note that SpaceX does not create these kinds of restrictions, and has therefore not experienced any slowdown in its launches or Starship development. It also appears to be experiencing no significant issues with COVID-19 infections.

The second issue is also in a sense a management decision. Sierra Nevada is subcontracting a lot of its work, and thus is at the mercy of other companies. Once again, SpaceX made a decision years ago to do as much as possible in-house. Thus, they are at no one’s mercy, and can push forward even as others cower in fear.

Overall, the pace of development at Sierra Nevada has not been impressive, but then, much of their work is being done by others, such as Lockheed Martin.

Sierra Nevada delays first Dream Chaser launch to ’22

1:22 pm

Sierra Nevada officials revealed yesterday that they are delaying the first test flight of their Dream Chaser reusable cargo mini-shuttle from late 2021 to some unspecified time in 2022.

‘’COVID has definitely played a role” in that delay, said Steve Lindsey, senior vice president for strategy at SNC Space Systems. One example he gave involved structural testing of the spacecraft’s cargo module at a contractor’s facility in San Diego. COVID-related restrictions prevented SNC engineers from being on site at that facility to oversee the tests. SNC developed a workaround by using a mission control center it developed for Dream Chaser in Colorado so those engineers could remotely oversee those tests. “That worked great. Unfortunately, it took probably three or four times as long as it should have,” he said.

A related problem, he said, involves suppliers who have had to suspend operations because of COVID-19 outbreaks at their facilities. There have also been technical challenges with Dream Chaser, although he did not go into details about specific issues. [emphasis mine]

I underline the unspecified technical issues, because I suspect they might be the real issue. SpaceX has not been slowed in any significant way due to the Wuhan panic, even though it deals with NASA also. I would therefore not be surprised if they are using COVID-19 as a cover for other issues.

It is a new craft, and problems are expected. I’d just rather they didn’t hide it. It contributes to doubts about the company, which by the way has been much slower in its development than one should expect. NASA awarded this contract in January of 2016, with the first launch then planned for as early as October 2019. It is now 2020, and the launch is still now two years away.

Sierra Nevada starts installing thermal tiles on Tenacity

6:05 pm

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”

7:52 am

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

9:54 am

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

11:01 am

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

9:34 am

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

9:04 am

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.
