Competition for ISS cargo contract reduced to three

9:50 pm

The competition heats up: With NASA once again delaying its decision on the next contract round for supplying cargo to ISS — this time to January — Boeing also revealed that NASA had eliminated the company from the competition, leaving only SpaceX, Orbital ATK, and Sierra Nevada in the running for the two contracts.

Earlier I had said that if the decision had been up to me, which of course it isn’t, I would pick Orbital and Sierra Nevada, since SpaceX and Boeing already have contracts to ferry crews to ISS. If you add Orbital’s Cygnus and Sierra Nevada’s reusable Dream Chaser, you then have four different spacecraft designs capable of bring payloads into orbit, a robust amount of redundancy that can’t be beat. When I wrote that I also noted that I thought it wouldn’t happen because Boeing’s clout with Congress and NASA would make it a winner.

With Boeing now out of the picture, it seems to me that the reason NASA has delayed its final decision again is that it wants to see what happens with the return to flight launches of Dragon and Cygnus in the next three months. A SpaceX Dragon success will cement that company’s position in the manned contract area, while an Orbital ATK Cygnus succuss will make picking them for a second contract seem less risky. In addition, maybe NASA wants Sierra Nevada to fly another glide test of its Dream Chaser test vehicle, and is now giving it the time to do so.

Sierra Nevada touts new work on Dream Chaser

9:14 pm

The competition heats up: As part of the normal lobbying that companies due prior the awarding of a government contract, Sierra Nevada today put out a press release describing the work they are doing to prepare both their Dream Chaser engineering test article (ETA) for glide tests and their Dream Chaser orbital vehicle for flight tests.

The announcement describes how they plan to do the next ETA glide test early in 2016, followed by orbital test flights of the orbital vehicle. Of course, that plan depends entirely on whether NASA picks them as one of the two companies for the second round of contracts to provide cargo to ISS.

The release however does include a nice picture of the ETA, which looks completely ship-shape following the failure at landing of one of its landing wheels during the first glide test. They have since replaced those wheels, which came from an airplane and were not the intending wheels for the actual spacecraft.

India’s spaceplane prototype to fly by August

10:16 am

The competition heats up: The first test flight of India’s prototype scaled-down version of a reusable spaceplane is expected by late July or early August at the latest.

It appears the Modi government is accelerating development of this mini-shuttle, which is essentially India’s version of Sierra Nevada’s Dream Chaser. If they build it first, it will mean they will have the chance to grab the business that Sierra Nevada has been hoping to grab.

NASA ISS cargo contracts delayed

8:15 am

The competition heats up: NASA has delayed, for the second time, when it will award its next round of cargo contracts to ISS, pushing the date back from June to September.

Though agency officials said they could not reveal why they had delayed the contract awards, they did say it was to gather more information. My guess is that the agency wants to see how SpaceX’s launch abort tests turn out this year before it makes a decision. If successful, they will then have the option of dropping SpaceX’s as a cargo carrier and pick someone else, possibly Dream Chaser, to provide up and down service to ISS. That way, they would increase the number of vehicles capable of bringing people and supplies up to ISS.

Delaying the award decision until September gives them time to evaluate the abort tests results, as well as give them a cushion in case those tests get delayed somewhat.

Sierra Nevada and Germany sign agreement

9:00 am

The competition heats up: Sierra Nevada has signed a new development agreement with Germany in connection with its Dream Chaser reusable mini-shuttle.

The agreement does not appear to involve any money and thus is largely symbolic. Nonetheless, it shows again that Germany is interested in having Dream Chaser built, and is throwing its support behind the manned spacecraft.

Sierra Nevada makes deal with Houston airport authority for Dream Chaser landings

10:19 am

Sierra Nevada has made an agreement with Houston’s airport authority to use Ellington Airport there to land its Dream Chaser spacecraft.

This announcement is part of the public relations push going on right now as NASA prepares to award its next round of cargo freighter contracts to two private companies. Sierra Nevada has bid to use an unmanned version of Dream Chaser to launch that cargo.

Sierra Nevada introduces its cargo version of Dream Chaser

6:35 pm

The competition heats up: Sierra Nevada has unveiled a revised cargo version of Dream Chaser, competing for NASA next round of freighter contracts to ISS.

They have made a number of changes, but the most significant is the new folding wings, allowing the spacecraft to fit inside the fairings of most rocket systems. This also eliminates one of the concerns I have read about the previous design on whether its wings could have withstood exposure to the maximum atmospheric stresses experienced during launch.

NASA explains why it picked Boeing over Sierra Nevada

9:38 am

In a report released by NASA late last week, the agency outlined the reasons it picked Boeing’s CST-100 manned capsule over Sierra Nevada’s Dream Chaser mini-shuttle for the second contract to provide manned ferry capabilities to ISS.

Sierra Nevada’s Dream Chaser spacecraft, which would take off on top of a United Launch Alliance Atlas 5 rocket and land on a runway like the space shuttle, is not as far along in development as the competing CST-100 and Crew Dragon capsules proposed by Boeing and SpaceX, according to a source selection statement signed by Bill Gerstenmaier, head of NASA’s human exploration and operations directorate. “A winged spacecraft is a more complex design and thus entails more developmental and certification challenges, and therefore may have more technical and schedule risk than expected,” Gerstenmaier wrote in the selection statement.

NASA wants to have the commercial crew capsules operational by the end of 2017 to end U.S. purchases of astronaut seats on Russia’s Soyuz ferry craft. Before NASA permits its astronauts to fly on the CST-100 and Crew Dragon, each spaceship will go through ground testing and complete unpiloted and crewed test flights.

The reasoning seems quite reasonable. It also suggests that Sierra Nevada might have a better shot at winning a contract during the next round for cargo, as scheduling will not be as critical since NASA has other alternatives to get cargo to ISS.

Dream Chaser lives on!

8:55 am

The competition heats up: Sierra Nevada reveals that it intends to bid its Dream Chaser mini-shuttle as an ISS cargo vessel in NASA’s next round of cargo contracts.

The company also says that it is continuing development of the shuttle right now, despite the present lack of a contract. If this is true, I would expect them to do, as promised, the additional glide tests they had planned, using their engineering test vehicle. If not, then the claim of further development is merely talk, a lobbying effort to improve their chances of winning the next contract.

Not that I blame them. I just think they would do themselves a lot more good doing an actual glide test.

Bringing Dream Chaser home

9:47 am

The competition heats up: At an space industry conference this week Sierra Nevada outlined the ability of Dream Chaser to land at almost any airport, including the many financial and safety advantages of that flexibility.

The story notes that because Dream Chaser would not need an unusually long runway, it could land at most airports. Also, because it would have no hazardous materials on board, removing it from the runway after landing would be simple and straightforward. You would simply tow it away. The biggest advantage of this, howevr, is that if the spacecraft was docked at ISS and there was an emergency that required immediate evacuation, bringing Dream Chaser and its passengers home to a runway will be possible any time.

This presentation is part of Sierra Nevada’s sales effort to find new backers for their spacecraft, now that NASA has begged out. I think they make a good sales pitch. I hope someone with money agrees.

Sierra Nevada announces an X-37B version of Dream Chaser

9:29 am

The competition heats up: In a press release today, Sierra Nevada has announced plans to build a version of Dream Chaser optimized for science research.

The Dream Chaser for Science, or DC4Science, spacecraft is designed to fly independently for short and extended durations to provide customers in such fields as biotech and pharmaceuticals, biology and life science, and material and fluid science with a flexible and evolvable vehicle easily suited for individual mission requirements.

More details here.

I call this version of Dream Chaser a variation of the X-37B because that is essentially what it would be, an unmanned reusable robot vehicle capable of taking experiments into space for periods of time and then bringing them safely back to Earth on a runway.

What Sierra Nevada is doing by announcing this now, shortly after the landing of the X-37B, is selling the concept in an effort to drum up customers who will then invest in the vehicle and thus help fund its construction.

Sierra Nevada fights back

9:15 am

The company that wants to build Dream Chaser has filed a lawsuit to prevent NASA from proceeding with its contracts with Boeing and SpaceX.

When Sierra Nevada had first protested the contract awards, NASA had first suspended work, then decided to allow work to go forward. This lawsuit is to prevent that from happening until after Sierra Nevada’s protest is resolved.

Here’s what I think is happening: Sierra Nevada has said it is going to submit a bid to NASA for the agency’s second round of cargo flights to ISS, proposing Dream Chaser as one of those unmanned freighters. By playing hard ball now with the manned contact awards, the company is creating leverage with NASA. Though no one can say this publicly, I am sure they are making it clear privately that if they get picked for the cargo contract, they will drop both their lawsuit and protest.

Why NASA picked Boeing over Sierra Nevada

9:43 am

A NASA internal document obtained by Aviation Week outlines the agency’s reasons for rejecting Sierra Nevada and its Dream Chaser spacecraft in its commercial manned space program.

Although the document praises Sierra’s “strong management approach to ensure the technical work and schedule are accomplished,” it cautions that the company’s Dream Chaser had “the longest schedule for completing certification.” The letter also states that “it also has the most work to accomplish which is likely to further extend its schedule beyond 2017, and is most likely to reach certification and begin service missions later than the other ‘Offerors’.”

Discussing costs, Gerstenmaier says that “although SNC’s [Sierra Nevada] price is lower than Boeing’s price, its technical and management approaches and its past performance are not as high and I see considerably more schedule risk with its proposal. Both SNC and SpaceX had high past performance, and very good technical and management approaches, but SNC’s price is significantly higher than SpaceX’s price.”

The document essentially was written, and probably leaked to the press now, to justify the political decision to give the contracts to Boeing and SpaceX. Thus, it waxes very enthusiastic about Boeing, since giving Boeing the contract, with the highest price and the least metal cut, needs some justification.

Stratolaunch and Sierra Nevada team up

9:14 am

The competition heats up: Sierra Nevada and Stratolaunch have signed an agreement to use a 3/4 scale version of Dream Chaser as the manned vehicle launched by Stratolaunch’s giant first stage airplane.

The Dream Chaser is a reusable, lifting-body spacecraft capable of crewed or autonomous flight. Dream Chaser is the only lifting-body spacecraft capable of a runway landing, anywhere in the world. Stratolaunch Systems is a Paul G. Allen project dedicated to developing an air-launch system that will revolutionize space transportation by providing orbital access to space at lower costs, with greater safety and more flexibility.

As designed, the Dream Chaser-Stratolauncher human spaceflight system can carry a crew of three astronauts to LEO destinations. This versatile system can also be tailored for un-crewed space missions, including science missions, light cargo transportation or suborbital point-to-point transportation. The scaled crewed spacecraft design is based on SNC’s full-scale Dream Chaser vehicle which, for the past four years, has undergone development and flight tests as part of NASA’s Commercial Crew Program.

More information is expected to be released about this partnership at the International Astronautical Congress taking place in Toronto this week.

Summing up, however, this partnership is a blatant challenge to NASA’s Orion/SLS system as well as its its commercial crew capsules built by Boeing and SpaceX. Sierra Nevada and Stratolaunch are essentially telling the world that they are going to build their own manned reusable vehicle, and that it is going to be better than anyone else’s.

Oh how I love competition. It sure makes things happen quickly.

Dream Chaser still alive!

9:22 am

The competition heats up: Sierra Nevada (SNC) has announced a new effort to gain international customers for its Dream Chaser manned spacecraft.

From the press release:

SNC’s Global Project offers clients across the globe access to low Earth orbit (LEO) without the time, resources and financial burden of developing the necessary capabilities or infrastructure to support a mature human spaceflight program. The Global Project utilizes the Dream Chaser spacecraft as a baseline vehicle which, in turn, can be customized by the client for an array of missions to support government, commercial, academic and international goals. The individual mission customization of the Global Project can be applied to both crewed and uncrewed variants for a single dedicated mission or suite of missions.

This is excellent news, as it tells us that the company is not giving up on the spacecraft, and intends to push hard to finish it. Not only are they working make it a viable product to many customers and thus obtain the construction financing to build it outside of NASA’s manned program, they also appear ready to bid on NASA’s second round of cargo launches, using Dream Chaser as an unmanned cargo freighter to ISS.

In fact, I would not be surprised if NASA chooses Dream Chaser over Dragon for that second round of cargo deliveries. Dragon is slated for the manned flights, so the agency will need another vehicle to replace it. Why not give the contract to Sierra Nevada, thus providing NASA with two manned vehicles and three cargo vehicles, all capable of accessing the station.

All in all, this increasingly looks like a win-win situation for everyone.

Sierra Nevada protests NASA manned spacecraft contact award

5:47 pm

The competition heats up: Sierra Nevada has formally protested NASA’s decision to award Boeing and SpaceX manned spacecraft contracts.

The company said late Friday that its bid in the NASA Commercial Crew Transportation Capability (CCTCap) was $900 million less than the bid submitted by Boeing, which won a contract worth as much as $4.2 billion to complete development, test fly and operate its CST-100 crew capsule. At the same time, SNC said, its proposal was “near equivalent [in] technical and past performance” source-selection scoring.

“[T]he official NASA solicitation for the CCtCap contract prioritized price as the primary evaluation criteria for the proposals, setting it equal to the combined value of the other two primary evaluation criteria: mission suitability and past performance,” the company stated. “SNC’s Dream Chaser proposal was the second lowest priced proposal in the CCtCap competition.”

In other words, they are challenging NASA’s decision to pick Boeing over them, as their proposal was far cheaper.

We all know that Boeing got the contract as much for its political clout as for its technical expertise. NASA wanted to make sure that members of Congress who promote the Boeing jobs in their districts would have nothing to complain about. Whether Sierra Nevada can get the government to look past that political clout is very doubtful, though I think I support them whole-heartedly in their effort.

The decision on manned spaceflight

9:23 am

The rumors are swirling. Today alone the news included three different articles about NASA’s upcoming decision to down-select to either one or two in its manned commercial crew program.

The third article above speculates that the decision will be made shortly after this weekend, maybe as soon as next week. It also outlines in nice detail the companies who are competing for the contract.

I strongly expect NASA to pick two companies, not one, as the agency has repeatedly said it wants to have redundancy and competition in manned space flight. To this I agree whole-heartedly. Right now, if I was a betting man (which I am not), I would pick SpaceX and Sierra Nevada as the two companies to get the nod.

If NASA only picks one company that I don’t think there is much doubt that it will be SpaceX.

And then again, government agencies, because of politics, have sometimes made some incredibly stupid decisions. For example, back in the 1970s the company that proposed the space shuttle was rejected for another big space company that had more political clout, which then turned around and essentially stole the first company’s designs to build the space shuttle from them. It just took longer and cost more.

Sierra Nevada abandons its own hybrid engine for Dream Chaser

1:13 am

The competition heats up: Sierra Nevada has decided not to use its own hybrid engine on its Dream Chaser manned shuttle.

With the apparent decision by Virgin Galactic to also abandon this engine, it would appear that hybrid rocket technology is not yet ready for prime time, if ever.

Posted from Spokane, Washington, where Diane and I will be visiting my oldest friend Lloyd and his family for the rest of the week.

What private manned spaceship will NASA pick?

8:47 am

Speculation grows on the upcoming down-select decision by NASA of its manned commercial space program.

Next up is the announcement of the transition to the Commercial Crew Transportation Capability (CCtCap) contracts, to be announced later this month, or early in September, depending on political direction. Although the source selection process is obviously an internal debate, with its results embargoed until the time of the NASA announcement, it is hoped that two of the commercial crew providers will move forward with additional funding.

At the ASAP meeting, Ms. Lueders expressed “NASA’s desire to continue the partnerships even after the announcement, including with companies not selected.” That continued association may be in the form of unfunded Space Act Agreements (SAA), not unlike that which Blue Origin is currently working under, as it develops a crew capsule outside of the trio working with CCiCAP funding. “People are recognizing the value of competition and have an appreciation for shared knowledge,” added Ms. Lueders. “NASA has learned from the companies and the companies have learned from NASA. It would be a big plus to continue the relationships.”

As to which companies are likely to win through to the CCtCap phase, that is a tightly kept secret. However, over recent months, sources have noted NASA’s strong affection toward the multi-capable Dream Chaser, while SpaceX has a growing track record with its Falcon 9 and cargo-Dragon combinations via its Commercial Resupply Services (CRS) missions. [emphasis mine]

My sense in the last few months has also leaned heavily in favor of Dragon and Dream Chaser, both of whom appear to be moving forward with construction at a fast pace. Boeing meanwhile has instead made it seem that it wishes to invest as little capital in its project as possible, unless it wins the competition. While the first two companies have unveiled real hardware, Boeing continues to show us mostly mock-ups.

The Dream Chaser test vehicle to fly again

10:08 am

The competition heats up: Sierra Nevada has announced that its Dream Chaser engineering test vehicle has been refurbished and will complete a number of manned and unmanned flight tests in the fall, with their schedule on track for a November 2016 orbital test flight.

“We will do between two and five additional flights. A couple will be crewed. As a result of the vehicle being upgraded, we will be flying our orbital flight software, which will give us about a year’s worth of advancement on the vehicle.” Flights are expected to last over a six- to nine-month period, he adds.

Sierra Nevada has also continued to expand its partnerships, both in the aerospace industry as well as with other countries. The first action is likely part of a lobbying effort to help convince NASA to choose it when it down selects its commercial manned program from three manned spacecraft to two later this year. The second action indicates that even if Sierra Nevada is not chosen by NASA, they plan to proceed to construction anyway to serve other customers.

Dream Chaser air frame unveiled

10:16 pm

The competition heats up: Sierra Nevada and Lockheed Martin today unveiled the composite airframe that will be used for the Dream Chaser spacecraft.

Essentially this is the first major structural component of the actual spacecraft. Lockheed was chosen by Sierra Nevada as the subcontractor to build it because of that company’s extensive experience with composites. It also gets them bonus points in Congress by using this powerful well placed company with many employees in important Congressional districts.

Sierra Nevada signs deal with Japan

9:14 am

The competition heats up: Japan has signed a development agreement with Sierra Nevada in connection with its Dream Chaser manned spacecraft.

I was also tempted to preface this post with the phrase, “Who needs NASA?” Sierra Nevada has a viable product that can get humans into space cheaply. Several countries, Germany, now Japan, want to get their own citizens into space, and have realized what a bargain Dream Chaser is. Sierra Nevada is taking advantage of this demand to sell its product worldwide. If Congress decides to defund them, or NASA decides not to pick them to continue development, they very clearly intend to build the ship anyway. It just won’t be used to put American astronauts into space.

An contract extension from NASA for SpaceX and Sierra Nevada

3:18 pm

NASA has given SpaceX and Sierra Nevada six additional months, until March 2015, to complete their last contractual milestones for building their manned spacecraft.

An amendment signed by William Gerstenmaier, NASA’s associate administrator for human exploration and operations, on May 16 gives SpaceX until March 31, 2015, to complete the 14th and final milestone under its $440 million CCiCap agreement — a pad abort test of its Dragon capsule. The test originally was planned for April 2014.

On May 19, Gerstenmaier signed a similar amendment to Sierra Nevada’s $212.5 million CCiCap award to extend work associated with flight tests of the company’s Dream Chaser engineering test article until March 31, 2015.

NASA’s third Commercial Crew partner, Boeing, is on track to complete all its milestones, worth a combined $460 million, by the end of August,

The significance of this extension is that it reveals something about the dates for both SpaceX and Sierra Nevada’s next flight tests. The previously date for the pad abort test for Dragon had most recently been set for this summer. They are obviously not meeting that schedule and need more time. Sierra Nevada meanwhile wants to fly its Dream Chaser test vehicle some more, but apparently needs time to get it flight ready after it sustained damage during landing on its one and only flight test.

In addition, this extension suggests something about NASA’s assessment of the efforts of all three companies. The agency is supposed to down select to two companies by the end of the summer. The extension suggests that they are hoping to keep all three companies funded so that they all build their spacecraft.

Sierra Nevada has announced that it plans to do additional test flights in 2014 of its prototype Dream Chaser engineering test vehicle

4:51 pm

Sierra Nevada has announced that it plans to do additional test flights in 2014 of its prototype Dream Chaser engineering test vehicle.

This is the same test vehicle that skidded off the runway during its first flight when one of its landing legs did not deploy. The company has never released any images of that smashup, but has said the craft was salvageable. I imagine this announcement is part of the continuing lobbying campaign by all the companies (SpaceX, Boeing, Sierra Nevada) competing in NASA’s commercial manned program. NASA is supposed to down select to two companies, maybe only one, by the end of the summer.

Sierra Nevada has successfully completed wind tunnel tests a several scale models of their winged spacecraft Dream Chaser.

8:38 am

The competition heats up: Sierra Nevada has successfully completed wind tunnel tests a several scale models of their winged spacecraft Dream Chaser.

It appears from these tests that the spacecraft’s design works better than expected during ascent and re-entry.

The article also gives a quick overview of the status of all three commercial companies, and from this it really looks to me as if Boeing is the least aggressive in pursuing its construction effort. This is merely an impression, and not to be taken too seriously, but it really does look like Boeing is playing the public relations game, doing as little work as possible while trying to garner the most publicity while waiting for the award of the contract.
