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.

Congress demands American rocket engines for military launches

9:11 am

In a letter written by a bi-partisan group of California legislators, Congress is pressuring the Air Force to replace the Russian engines on its Atlas rocket, and do to it competitively.

“While it is important that we invest in new technology, the problem of Russian reliance calls for an immediate solution,” states the Sept. 22 letter, which was signed by 32 of California’s 53 members of the U.S. House of Representatives. … In the letter, the House members said they are “troubled by the Department’s willingness to continue sourcing this engine from the Russian government, apparently in the hope that the situation with Russia does not deteriorate further, and that Russia chooses to continue supporting U.S. military launches — while it ignores American sources of engine technology. “We strongly encourage you to recognize that the United States — and specifically, California — today produces technology that exceeds any capability offered by Russian systems,” the letter said. “It is time for the Department to look to these existing U.S. engine manufacturers and launch vehicle providers.”

This letter suggests to me that SpaceX has won its battle with the Air Force and is going to get some launch contracts. It also suggests that ULA and Blue Origin will likely be able to get the funding from Congress to finance the design and construction of the replacement engine they have jointly proposed.

Washcloth delays SLS engine tests

8:59 am

The testing of an engine for the giant SLS rocket will be delayed because engineers have found the remains of a washcloth in the ducts of the test stand at Stennis Space Center.

The investigation found the fibers belong to a cotton shop rag from a weld shop that had been involved with working on the LOX duct ID surface during manufacture. The roughened surface (of the duct) was where the fibers were observed to be hanging up on.

The investigation team reported that, under microscope inspection, a piece of the run duct stock showed metallic particles loosely adhered to the ID surface and embedded in the ‘machining’ groves. Several were easily dislodged and identified as ID surface material. “A tape sample was pulled from the same stock (after an identical cleaning process) and produced a rather large quantity of particles. This is an unacceptable condition and it was agreed that the entire run duct will need to be replaced or reworked (~30-ft of pipe),” added the investigation notes.

Replacing the duct will cause a several month delay in the test program. Fortunately for NASA, they have some wiggle room (for the moment), since the entire SLS schedule has already slipped a year to 2018.

Nonetheless, do not be surprised if this is only the first of many further delays.

Mangalyaan’s first global images of Mars

8:49 am

Indian engineers have released the first global images taken by Mangalyaan.

As MOM’s orbit is highly elliptical, reaching from 262 miles (periareon — closest approach) to 47,841 miles (apoareon — farthest extent), we can expect a lot more global views from Mars’ newest satellite, providing us with a beautiful global perspective of a planet that currently has seven robotic missions (from three different space agencies) exploring it.

These images suggest that a dust storm is beginning to stir on the Martian surface.

Something keeps coming and going in a sea on Titan

11:14 am

Cassini images taken in 2007, 2013, and 2014 of one of Titan’s largest hydrocarbon seas find that a mysterious feature there keeps appearing and disappearing.

The mysterious feature, which appears bright in radar images against the dark background of the liquid sea, was first spotted during Cassini’s July 2013 Titan flyby. Previous observations showed no sign of bright features in that part of Ligeia Mare. Scientists were perplexed to find the feature had vanished when they looked again, over several months, with low-resolution radar and Cassini’s infrared imager. This led some team members to suggest it might have been a transient feature. But during Cassini’s flyby on August 21, 2014, the feature was again visible, and its appearance had changed during the 11 months since it was last seen.

Scientists on the radar team are confident that the feature is not an artifact, or flaw, in their data, which would have been one of the simplest explanations. They also do not see evidence that its appearance results from evaporation in the sea, as the overall shoreline of Ligeia Mare has not changed noticeably. The team has suggested the feature could be surface waves, rising bubbles, floating solids, solids suspended just below the surface, or perhaps something more exotic.

That the seasons are slowly changing on Titan is probably contributing to the transient nature of this feature.

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.

India: Space success vs red tape?

8:43 am

Even as India celebrates the success of its Mars orbiter Mangalyaan, its aerospace industry complains of red tape and a slow-moving bureaucracy.

Between 2007 and 2012, ISRO accomplished about half of its planned 60 missions, government data showed. The government cited “development complexity” as the reason for the delay in some missions. Between 2012 and 2017 the target is 58 missions. The agency has completed 17 missions so far, and ISRO did not say why the number remained low. Some company executives and experts do not see that changing any time soon, with the absence of heavy rocket launchers, too few launch facilities and bureaucratic delays hampering growth.

I could also say that the battle is now joined between India’s military-industrial complex and private enterprise. With a government now in power that claims to be pro-business, we shall see where this battle leads.

Soyuz docks successfully with ISS

12:54 am

Despite the failure of one solar array to deploy, a Soyuz capsule carrying three astronauts successfully docked with ISS today.

The solar array issue, still unresolved, needs to be figured out, as this Soyuz spacecraft must serve as one of ISS’s lifeboats for the next few months. Without that array the spacecraft will have limited power, and will definitely not be considered the best way home should something go wrong on the station.

A solar panel on manned Soyuz fails to deploy

5:00 pm

One of the two solar panels on the manned Soyuz capsule transporting three astronauts to ISS has failed to deploy.

“According to our data, one of the solar panels is still unable to unfold for reasons unknown. But preliminary data suggest that it will not impede [the spacecraft] from docking to the ISS. They have carried out a maneuver just now which involved all of the spacecraft’s engines, all systems are running smoothly, the crew is OK,” the source in the agency said.

Because they are flying the fast route to ISS a shortage of power is not as critical. However, this failure once again indicates the increasing quality control problems faced by the Russian aerospace industry. In past decades these problems simply did not happen, especially on their manned missions. Now they are happening with increasing frequency.

Mangalyaan sends its first Mars pictures

9:15 am

Mangalyaan's first image of Mars

Indian engineers have posted Mangalyaan’s first image on the spacecraft’s Facebook and Twitter accounts, as well as presented the photo to their nation’s leader.

My first reaction when I looked at the image above was an immediate flashback to 1969, when the American probes Mariner 6 and Mariner 7 flew past Mars, taking images of its cratered southern hemisphere and thus making scientists think for several years that Mars was not much different than the Moon. The Indian image is of about the same quality, and shows lots of moon-like craters.

Image if this was the first close-up image of Mars anyone had ever seen. It would be very easy to assume that Mars is pockmarked with craters everywhere, just like the Moon.

Europe struggles to contain costs on its next generation rocket

9:02 am

New budget estimates for replacing Arianespace’s Ariane 5 rocket now say that they will have to include the construction of an entirely new launchpad, raising costs.

Nonetheless, Europe is trying to keep its per launch cost down and competitive.

ESA and the Airbus-Safran joint venture that proposes to manage Ariane development also floated per-launch costs that were lower than previous estimates. The lighter-version Ariane 62, with two solid-rocket boosters, could be built for as little as 65 million euros assuming a nine-per-year launch rhythm, officials said. The heavier Ariane 64, intended mainly for the commercial market and capable of carrying two satellites weighing a combined 11,000 kilograms into geostationary transfer orbit, could be built for 85 million euros each, again assuming a nine-per-year production rate.

These numbers are tiny compared to what they have charged in the past, and though higher than SpaceX’s, are within a price range that will keep them in business, assuming they can achieve them.

Why India’s Mars probe was so cheap

5:32 pm

Alan Boyle has some interesting thoughts on why it cost India so little, less than the budget of the movie Gravity, to build and send its probe Mangalyaan to Mars.

The $74 million Mars Orbiter Mission, also known by the acronym MOM or the Hindi word Mangalyaan (“Mars-Craft”), didn’t just cost less than the $100 million Hollywood blockbuster starring Sandra Bullock. The price tag is a mere one-ninth of the cost of NASA’s $671 million Maven mission, which also put its spacecraft into Mars orbit this week. The differential definitely hints at a new paradigm for space exploration — one that’s taking hold not only in Bangalore, but around the world. At the same time, it hints at the dramatically different objectives for MOM and Maven, and the dramatically different environments in which those missions took shape.

Read it all. It gives us a hint at the future of space exploration.

Russia announces plans to fund its share of ISS through 2025

8:50 am

In a somewhat unexpected development today, Russian Deputy Prime Minister Dmitry Rogozin revealed today that Russia intends to spend $8.2 billion (321 billion rubles) on research and development at the International Space Station through 2025.

“The 2016-2025 draft of the target federal program provides for allocating 321 billion rubles for the ISS development and operation, including the creation of new modules for unmanned spacecraft,” Rogozin said during a visit to a cosmonaut training center. “Russia channels considerable funds into development of this area of Russian space science. We are now thinking of research projects designed to explore outer space, as well as new projects in manned cosmonautics,” Rogozin said.

Up until now the Russians have been unclear about what they intend to do at ISS. NASA had asked them to extend the partnership to 2024. Their initial response was almost hostile, with Rogozin even threatening to stop flying American astronauts to ISS on Russian Soyuz rockets/capsules. Now it appears that they have decided to up their participation with new modules and agree to the extension.

Moreover, Rogozin’s statement suggests they are going to take a more independent position when it comes to human research in space. Up until now, they have allowed NASA a veto on flying any long manned missions on ISS, which is why no yearlong expeditions prior to next year’s have taken place. NASA kept saying no. This report suggests that once we have our own methods for getting astronauts to ISS they are going to go their own way and begin flying their own long term missions to ISS. We will fly our astronauts there on our schedule, and they will fly their astronauts there on their schedule.

Should make for some interesting news stories, eh? Will Russian and American astronauts even be allowed in each other’s modules? I am reminded of stories of messy divorces where the couples still had to live in the same house.

Success for India’s Mars Orbiter Mission

8:33 am

The competition heats up: On Wednesday morning India’s Mars orbiter Mangalyaan successfully fired its engines and attained Mars orbit.

More here.

There are probably three dozen stories in the India press today extolling this success. And there should be. As described in detail in the second link above, India did this mission smart, simple, and fast, showing everyone else that a science mission doesn’t have to take a decade and a billion dollars to be get built.

I expect that this success will quickly lead to the Indian manned flight tests their space agency ISRO has been advocating for the past few years.

The Great Space Race

1:00 pm

Yesterday the private commercial launch company SpaceX broke ground on its own private spaceport near Brownsville, Texas.

“This feels great. It feels like the future,” [SpaceX founder Elon] Musk said at the ground-breaking. … He intends to have the first launch in late 2016, with an initial 12 launches a year. Ultimately, “thousands of launches,” he projected. Furthermore, “when we start doing commercial crew activities, I would expect us to launch a crew from here,” he said.

The significance of this construction is not trivial. This will be the first spaceport built by a private company that will be used to launch its privately-built commercial rockets, and will do it for profit. Other spaceports have been established in the last decade for the purpose of private space tourism, but none have seen anything fly, and all those spaceports were some form of quasi-government operation.

SpaceX’s Brownsville spaceport, rumored to be dubbed Mars Crossing, is not a government-run operation, however. It will be wholly owned and operated by the company, and is being built to allow them to launch commercial satellites unconstrained by the rules that make launches from the government controlled spaceports at the Kennedy Space Center as well as Vandenberg Air Force Base in California difficult and complicated.

This ground-breaking also comes on the heels of last week’s announcement that SpaceX and Boeing have been chosen by NASA to build spacecraft to ferry human astronauts to and from the International Space Station.

It also comes at the same time the Russian government has reorganized its entire aerospace industry to place it under government control, committed billions for the accelerated construction of a new spaceport on Russian territory, and launched the first test flight of its own new rocket, Angara, designed to compete for commercial market share while also reenergizing the entire Russian space effort.

Nor is that all.

MAVEN enters Mars orbit

7:25 pm

Upon completion of its engine burn this evening at 10:10 pm (eastern), MAVEN successfully entered Mars orbit.

Stephen Clark’s status updates on Spaceflight Now were accurate, informative, and right on the money. The live telecast on NASA-TV was confusing, idiotic, distracting, and uninformed. They never once announced when the engine burn had started, ignored the reactions of the people in the control room when they cheered some important event, and spent a lot of time discussing facts that were irrelevant to this event, which is “Will MAVEN achieve orbit!?” Worst of all, the male “anchor” was clearly ignorant of the mission while the female “anchor” spoke in a sing-song manner as if her audience were kindergarten toddlers who needed careful herding. All in all, it was embarrassing to watch.

They did manage to shut up just in time to catch the announcement from mission control that telemetry had confirmed that MAVEN had reached orbit. They then went back to chattering about irrelevant stuff. As I said, embarrassing.

India inks space deal with China

10:06 am

The competition heats up: India has signed a cooperative agreement with China to work together on several space projects.

Asked about the areas of focus, [Isro chairman K Radhakrishnan] said: “Right now, broadly speaking, it will be natural disasters and remote sensing, which are natural choices. But by March-April 2015, the joint working team would have prepared a roadmap, chalking out various options and opportunities for concentrated efforts in space exploration.”

This article is among a lot of articles from India this week about space and the upcoming orbital insertion of their Mars Orbiter Mangalyaan. As I’ve said repeatedly, this emerging prosperous and capitalist nation is space happy!

Also, when you click on the link make sure you scroll down to read the secondary sidebar piece at the bottom titled “After Mars, Kathakali beckons Isro chief.” There they describe the other culture interests of the head of India’s space agency, and how he plans to spend his time after he steps down in December. It will give you a flavor of India’s culture and how it differs from ours, even as it strives to emulate us.

Falcon 9 launch puts Dragon in orbit

11:03 pm

The competition heats up: SpaceX’s Falcon 9 rocket has successfully put its fifth Dragon cargo freighter into orbit, with a docking at ISS scheduled for Tuesday.

Spaceflight Now’s status update above also noted that this is the 13th launch of a Falcon 9 rocket since 2010. All these flights have successfully put their primary payloads into orbit as promised, an amazing track record for a new rocket built by a new company only in existence for less than a decade.
