Virgin Galactic outlines near term test flight schedule

10:06 am

The competition heats up: In a newspaper interview, the CEO of Virgin Galactic has outlined the company’s flight plans for SpaceShipTwo in the coming months, leading hopefully to its first commercial flights.

“We expect to get to space altitude in a short number of flights, assuming the rocket performs as expected,” Whitesides told the Journal. “Scaled made it to space in four flights with SpaceShipOne. I believe it will be a little more than that for us, but not dramatically so.”

Once SpaceShipTwo successfully reaches space, Scaled Composites will turn over the rocket to Virgin Galactic for its commercial operations based in New Mexico. Virgin has already taken control of the mothership, which it flew to Spaceport America for some initial test operations in September. “Once we take control of SpaceShipTwo, we expect to do some more testing here in New Mexico, but that will primarily be efficiency testing rather than technology testing,” Whitesides said. “It will give pilots an opportunity to train at this airfield after Mojave to practice things like coming in on final approach.”

As much as I have expressed strong skepticism in recent months of Virgin Galactic’s promises, I truly hope this happens, and soon.

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.

Update on Bigelow’s ISS module

9:14 am

This article is a nice overview of Bigelow’s planned inflatable module for ISS, due to launch next year, and includes some good images.

I found this paragraph especially intriguing:

Earlier this year, Bigelow announced how much it’ll cost you to spend some time inside the BA 330 when it launches. Expect to pay $25 million for a sixty day lease of one-third of the station — if you can get yourself there and back. Should you need a ride, round-trip taxi service between SpaceX and your local launching pad will run you an additional $26.5 million.

That’s a total cost of just over $50 million for a sixty day stay in space.

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.

Orbiting X-37B to land on Tuesday

9:08 am

After twenty-two months in orbit, on its second space mission, the Air Force plans to bring the X-37B back to Earth this coming Tuesday.

The exact time and date will depend on weather and technical factors, the Air Force said in a statement released on Friday. The X-37B space plane, also known as the Orbital Test Vehicle, blasted off for its second mission aboard an unmanned Atlas 5 rocket from Cape Canaveral Air Force Station in Florida on Dec. 11, 2012. The 29-foot-long (9-meter) robotic spaceship, which resembles a miniature space shuttle, is an experimental vehicle that first flew in April 2010. It returned after eight months. A second vehicle blasted off in March 2011 and stayed in orbit for 15 months.

SpaceShipTwo poised for powered test flights

3:51 pm

Virgin Galactic officials outline the status of SpaceShipTwo, suggesting that powered flight tests are finally about to begin.

Providing a rare glimpse of progress on a second spacecraft under assembly at sister organization, The Spaceship Co., Virgin Galactic Vice President of Operations Mike Moses says, “we are ready for space.” A former NASA launch integration manager for the space shuttle, Moses adds that SS2 “has been in modification, getting retrofitted ready to resume powered flights.” He notes that “those are going to start imminently—literally very imminently.”

Commenting on the extensive gap between now and the last rocket flight in January, Moses says, “It might seem a long time since our last powered flight-testing and that maybe nothing has been happening, but [ground testing] has been happening.” Tests have largely focused on ground-firings of a hybrid rocket motor fueled with polyamide-based plastic in place of the hydroxyl-terminated polybutadiene, a form of rubber used for the first series of powered tests. Although this fuel had been used successfully in SpaceShipOne, the vehicle developer Scaled Composites and Virgin Galactic encountered fuel-burn stability and power issues as they tried to scale the Sierra Nevada Corp.-provided hybrid motor up to the size required by the larger SS2.

It appears my guess was right and that the last two glide tests were to retrofit SpaceShipTwo for the new fuel and engine. This has now been accomplished, and they are preparing to begin powered flight tests.

The article also describes work on a second SpaceShipTwo, which when completed will give Virgin Galactic the beginnings of a fleet of ships.

Launch abort system installed on Orion for December test flight

9:14 am

Engineers have installed a test version of the launch abort system (LAS) for the first test flight of the Orion capsule in December.

The LAS will not be active during the uncrewed EFT-1 mission, but during future missions it will be equipped to act within milliseconds to pull the spacecraft and its crew away from its rocket so that Orion could parachute safely back to Earth.  While the abort motors  are inert and not filled with solid fuel, the LAS will have an active jettison motor so that it can pull itself and the nose fairing away from the spacecraft shortly before Orion goes into orbit. The flight test will provide data on the abort system’s performance during Orion’s trip to space.

Based on what I know of the Orion/SLS launch schedule, I don’t think NASA ever intends to test it during a full launch of the SLS rocket. For one thing, the rocket is too expensive and NASA can’t afford to waste a launch just to test this one component. For another, the rocket’s development is too slow as it is, with the first launch not scheduled until 2018 and the first manned flight not until 2021, at the earliest. If they add a launch test of the abort system, NASA might not fly an SLS manned mission until late in the 2020s.

Meanwhile, NASA is sure insisting that SpaceX do such tests. And they will, since their capsule and rocket is affordable and quick to launch. What does that tell us about the two systems? Which would you buy if you were the paying customer?

Oh wait, you are the paying customer! Too bad you your managers in Congress don’t seem interested in managing your money very wisely.

Air Force to take over two former shuttle hangers in Florida for its X-37B program

8:47 am

In an effort to find tenants for its facilities, the Kennedy Space Center is going to rent two former shuttle processing hangers to Boeing for the Air Force’s X-37B program.

NASA built three Orbiter Processing Facilities, or OPFs, to service its space shuttle fleet between missions. All three are located next to the iconic Vehicle Assembly Building at the Florida spaceport where Apollo Saturn 5 moon rockets and space shuttles were “stacked” for launch. Under an agreement with NASA, Boeing will modify OPF bays 1 and 2 for the X-37B program, completing upgrades by the end of the year.

The company already has an agreement with NASA to use OPF-3 and the shuttle engine shop in the VAB to assemble its CST-100 commercial crew craft being built to ferry astronauts to and from the International Space Station. The company says up to six capsules can be processed in the facility at the same time.

The most important take-away from this news is that it strongly suggests the Air Force now intends to expand the X-37B program. They will not only be flying both X37B’s again, they might even planning to increase the fleet’s size from two ships.

Independent Arianespace investigation cites design error as cause of Russian launch failure

8:36 am

A just released independent investigation by Arianespace of the Soyuz rocket launch failure that put two European Galileo GPS satellites in the wrong orbits has concluded that the design of the Fregat upper stage, not an assembly error, was at fault for the failure.

The upper stage was not oriented correctly because fuel lines to thrusters had become frozen.

The freezing resulted from the proximity of hydrazine and cold helium feed lines, these lines being connected by the same support structure, which acted as a thermal bridge. Ambiguities in the design documents allowed the installation of this type of thermal “bridge” between the two lines. In fact, such bridges have also been seen on other Fregat stages now under production at NPO Lavochkin. The design ambiguity is the result of not taking into account the relevant thermal transfers during the thermal analyses of the stage system design.

That the Russian investigation found that this arrangement of feed lines happened once in every four stages that were assembled still suggests sloppiness, if not in assembly then in design. The Arianespace investigation, though thorough, thus appears to me to be trying to provide cover for thier Russian partners here.

XCOR sells its Lynx suborbital spaceplane

10:19 pm

This NBC story tries very hard to help XCOR sell its Lynx suborbital space plane, but I found myself very unimpressed. To me the images suggested instead that little progress has occurred in recent months, and that the project has stalled.

I hope I am wrong, but this whole story reminded me strongly of many of Richard Branson’s efforts to sell Virgin Galactic, which have so far proven to be vastly overstated.

Successful American spacewalk today on ISS

9:55 pm

Two American astronauts today successfully completed the first American spacewalk this year on ISS.

The spacewalk, known as US EVA-27, was originally slated to occur in August, but was postponed due to concerns with the batteries in the Extravehicular Mobility Unit (EMU) spacesuits, which necessitated a delay while new Long Life Batteries (LLBs) were launched to the ISS aboard the recent CRS-4 Dragon and the Soyuz TMA-14M/40S on September 25, and subsequently installed into the suits.

The work done was mostly clean-up in preparation for a series of future spacewalks to reconfigure the American sections of ISS so that it can allow docking of two private manned capsules as well as two private cargo freighters.

SpaceX wins safety design award

4:52 pm

I post this story about SpaceX winning an award for its safety-in-design work mostly to illustrate again that, except for one lone commenter on my webpage, most of the aerospace industry recognizes the generally good work that SpaceX has been doing. Not only do their recognize it, they have found themselves struggling to meet the competitive challenge that SpaceX now represents, an effort that has been all to the good for everyone in the space industry.
