Russia Looks at Methane Propulsion for Next Generation Soyuz

Soyuz

With 1,806 launches to its credit,  the most recent a military satellite launched from Plesetsk on June 7th, the Russian Soyuz remains in a class all by itself.  In all likelihood it will remain that way.  Anatoly Zak reports on Russianspaceweb.com today that engineers at Tsskb Progress in Samara, which manufactures the Soyuz booster, are considering a future “Soyuz 5″ launch vehicle powered by engines burning methane rather  than kerosene.

It is interesting to note that a “lite” version of the  Soyuz, designated the Soyuz 1 is  directly related to an ongoing engine controversy in the United States.  The first Soyuz 1, which is powered by a single, legacy NK-33 engine is currently at Plesetsk undergoing further tests before it makes a planned first flight scheduled for later this year. Russia has been trying to build the case to restart production of the NK-33 in order to provide a long term future for the  lighter, less expensive version of its historic launcher which does not include the familiar four strap-on first stage boosters.

The NK-33 has already been given new life in a renovated version modified by Aerojet  and labelled the AJ-26, where it recently made history by powering the first launch of Orbital Science Corporation’s Antares booster. Concerned that the existing stock of 40 year old engines would run out, OSC  reportedly sought to acquire the larger RD-180 used on the ULA Atlas V, for future versions of the Antares, only to be denied due to an alleged exclusive access provision negotiated by United Launch Alliance. The issue is currently being investigated by the Federal Trade Commission.

According to a report in Space New today,   events have taken a new turn with an announcement coming out of the Paris Air Show that newly named Aerojet-Rocketdyne can supply new engines if OSC is willing to sign. No doubt supporters of the Soyuz -1 hope it will do just that.

While today’s story on the Soyuz 5 is hardly definitive, as various Russian design bureaus frequently put forward new launch proposals which are never developed, the focus on a methane based engine indicates some interest in this largely unexplored but very appealing fuel selection that, according to comments made by Elon Musk late last year, is also drawing notice from SpaceX.

NASA’s Asteroid Retrieval Mission May Lack a Viable Target

Looking for You Credit : NASA

A Future in Space Operations presentation earlier this week by Dan Adamo, which can be found here, highlights a potential serious problem with NASA’s proposed asteroid capture mission.  The presentation focuses on a “V” plot  which shows a range of Near Earth Asteroids grouped into three different classes by their orbital characteristics.  Some NEAs falling within in the V meet the basic guidelines as outlined in the NEO HSF Accessible Targets Study (HNATS) for a crewed mission.   The guidelines call for the asteroid to be in a certain size range, be accessible with a certain minimal velocity change to get there and back, as well as fall within the a few degrees of Earth’s own orbital plane. Finally, the asteroid’s orbits must place them within reach of Earth’s within the time frame of the proposal, by 2030.  There are a number of known NEAs which might otherwise be ideal, but which are on long orbits which carry them too far from Earth for consideration.

As it turns out, even though the Asteroid Retrieval Mission (ARM)  relieves NASA of the difficulties of an extended duration manned mission to travel to an asteroid and study it,  the new criteria imposed;  a close Earth approach, diameter of 7 – 10 meters, and a mass of  around 500 metric tons,  appears to reduce the number of possible targets to zero. Meaning that as of this  moment,  NASA does not have a target that aligns with the plan to capture and return to it Cis-Lunar orbit in time to neatly coincide with an early mission for the Orion spacecraft. Oops.

As the author goes on to point out, there are other options, but they bring other problems.  Still working with known asteroids, the field of possible visits could be expanded by changing the mission from capturing a smallish free flying asteroid, to instead “landing” on a body much too large to return, gathering samples, possibly large ones from loosely accreted materials, and bringing them back to the Earth Moon system.  Besides even further diminishing the popular appeal of a proposal which has failed to generate much enthusiasm to begin with, this option runs the risk of targeting an asteroid which does not readily yield pieces of itself.  An even more embarrassing prospect is targeting an object whose orbital characteristics are not perfectly understood, and missing it entirely. 

On the other hand,  NASA could instead seek to expand the field of available candidates by searching for more NEAs in the first place.  This option has the decided benefit of helping to identify and characterize the much smaller group of Earth crossing asteroids which pose a potential threat to all of us. This of course, is the mission of the B 612 Foundation and its Sentinel project, so there is clear room for collaboration. The problem here is one of time, in that there isn’t enough of it. 

The asteroid retrieval plan is conceived around highly efficient, but painfully slow electric propulsion to reach a target and then gently direct it our way, a process which will take several years flight time.  Any new start, pre-cursor mission to fund, design, build, launch and operate a telescope to search for better targets would need to be gearing up, or already underway to allow time for actual retrieval mission, and that isn’t happening.

ULA Investigated for Anti Trust Violations

Trouble ? Credit : PWR

Trouble ?

What was already likely to not be a very happy week at United Launch Alliance just got a whole lot worse. Only a day after SpaceX entered into an agreement with the Air Force to begin the process of qualifying its boosters for EELV business,  Reuters is reporting that the Federal Trade Commission is opening an investigation into allegations that the ULA prevented RD Amross, a joint venture of Pratt and Whitney Rocketdyne and NPO Energomash, from selling its Russian built RD-180 main rocket engines to Orbital Sciences Corporation for its Antares booster.

The timing of the allegations is fascinating, if more than a little confusing.  Just two days ago the FTC approved the purchase of PWR by GenCorp, the same company which also owns Aerojet, for $550 million from current owner United Technologies. Given that the result of the acquisition will be a new monopoly,  specifically that of large liquid rocket engines, it seems a little late to be raising this issue.

 It could be however, that the FTC, which voted 4-0 to approve the purchase , felt compelled to do so on the basis of Department of Defense assertions that it was needed for “national security” purposes, including the catchall justification of  protecting the industrial base.  The arguments put forward in this June 6th DOD response to the FTC, are nearly comical, and just as demonstrably absurd as the similar arguments put forward in justifying the formation of United Launch Alliance in the first place. But then again, as much larger ongoing events would seem to indicate, the “needs” of national security are being used to justify a whole range of activities many would consider questionable.  

Having acceded to the DOD request, it appears the FTC could be making a point by pursuing the RD-180 issue. According to Reuters,  which cited “industry sources “  Orbital Sciences, anticipating the day that the stock of Russian built Aerojet modified AJ-26 engines runs out,  has made multiple inquiries into purchasing the RD-180, only to be rebuffed, presumably at the behest of ULA which has fought tooth and nail to prevent SpaceX from entering into the EELV market,  and recently scored a pre-emptive victory over Orbital Sciences when it convinced the Air Force to fund a dual launch adapter for the Atlas-V for GPS-III satellites, a market for which the Antares could be expected to compete.

OCS’s reasons for pursuing the RD-180 are interesting, indicating that the company would like to solidify  its entry into the liquid fueled launch vehicle business which took a big step forward with the recent maiden launch of the Antares.  It suggests that even for a fairly conservative, publicly traded company such as Orbital Sciences, the market pricing distortion created by the ULA monopoly is so extreme, that its own analysts believe there is room for entry.   It also at least raises the question of whether or not OSC might have otherwise pursued a liquid fueled first stage for the booster it is supplying to Stratolaunch, but was left with little choice but solids after it was unsuccessful in acquiring the RD-180.

Everybody is of course clamming up at this point, but it would be hard to argue that story doesn’t fit a pattern of behavior which began before the merger between Lockheed Martin and Boeing launch efforts which formed ULA , when the pre-merger courtship was highlighted by lawsuits from both parties claiming the other was attempting to constrain trade, a result of Boeing’s admission that it was in possession of the thousands of pages of proprietary Lockheed Martin documents regarding the Atlas-V.  

Given that ULA bases much of its current justification for excessively high prices on the reliability of its two booster lines,  an argument thoroughly undercut  by the equally reliable, but commercially successful Ariane-V,  it is easy to see the potential threat posed by the prospect of an RD-180 engine, which is the reason for much of that reliability,  powering a domestic competitor.  The ads almost write themselves.   “All the reliability,  half the price.”    

The fact that the entire substance of the allegation is over an American company preventing another American company from buying a Russian built main engine for use after the latter company’s original source of 40 year old Russian engines runs out, highlights the fact that efforts to protect the industrial base have not merely failed, they have become a farce as well.

SpaceX Takes Another Step into EELV Market

The U.S. Air  Force Space and Missile  Systems Center announced yesterday that it has signed a Cooperative Research and Development Agreement (CRADA) with Space Exploration Technologies Corp., paving the way for the company to take the next steps along the pathway to entering the EELV business as outlined in the New Entrants Certification Guide which was introduced in October 2011.  According to the press release the CRADA 

  ”enables the Air Force to evaluate the Falcon 9 v1.1 launch system according to the Air Force’s New Entrant Certification Guide (NECG). As part of the evaluation, SMC and SpaceX will look at the Falcon 9 v1.1′s flight history, vehicle design, reliability, process maturity, safety systems, manufacturing and operations, systems engineering, risk management and launch facilities. SMC will monitor at least three certification flights to meet the flight history requirements outlined in the NECG. Once the evaluation process is complete, the SMC commander will make the final determination whether SpaceX has the capability to successfully launch NSS missions using the Falcon 9 v1.1.”

As the announcement indicates,  it will still be some time before SpaceX will be in a position to compete for EELV launches,  and there  is no word on when the Air Force evaluations will begin.  Presumably however,  SpaceX would want to wait until after the new booster has successfully completed the first few flights on its manifest, and in particular delivered its first commercial communications satellite to GTO,  which should come with flight number and the launch of  SES-8 out of Cape Canaveral.  

SpaceX will enter into a separate certification agreement with the Air Force to enable the Falcon Heavy to compete for EELV class launches, a process which will probably quite a bit longer, as the company currently lists three launches on its manifest for the triple core booster; a demo flight which will likely take place in 2014, followed by two flights the following year, one of which is a demonstration flight for the Air Force,  labelled Space Test Program -2, contracted under the  Orbital/Suborbital-3  (OSP-3) program.  The remaining Falcon Heavy flight currently on the manifest is for Intelsat, but that may not be the case for long. 

A sucessful introductory campaign for the Falcon 9 v1.1, the core of the Falcon Heavy, beginning with the launch of Cassiope out of Vandenberg, and followed by the SES launch,  is likely to open the door heavy and super heavy class comsat launches in short order. 

In a related note, SpaceX has notified the Waco Tribune that another “loud” test similar to 112 second run on Friday evening is imminent.

China’s Shenzhou-10 mission lifted off successfully this morning at 5:38 a.m. EDT, (5:38 p.m. local) sending the crew of three on what is expected to be a 40 hour rendezvous with the awaiting Tiangong-1  space station. During what the Chinese space agency has described as an “applications oriented flight,”  the astronauts will conduct both a manual and an automatic docking with the station to improve on the nation’s experience  prior to beginning construction of a larger,  3-person station with rotating crews planned for 2020.  

Today’s liftoff took place aboard a Long March 2F rocket, which is a 2-stage, all hypergolic launch vehicle, equipped with 4 strap-on liquid fueled “stage 0″ boosters which are also hypergolic.  Although China is working on both kerosene / liquid oxygen and  fully cryogenic hydrogen / oxygen boosters, progress has thus far been slow.
