Update on Russia’s proposed new space station project

8:58 am

Another article has been published in Russia describing the possibility of that country pulling out of ISS and building its own space station, as soon as 2017.

My impression of these stories is that the Russian government is considering taking the modules it has been slowly building for ISS and instead using them to assembly an independent station orbiting the Earth at an almost polar orbit, thereby giving them a much more complete view of their own country as well as the rest of the world.

Russias pulling out of ISS in 2020

8:41 am

Another news story from Russia has confirmed that the Russian government intends to break off its partnership at ISS in 2020, and that it will instead start assembling its owns space station in 2017 and will use some modules now docked with ISS to do it.

This event was always possible, and one of the many reasons I always opposed Bill Clinton’s decision to form the ISS partnership. The partnership acted as a crutch for NASA and the U.S, allowing us to avoid spending the money to build a self-sufficient space station. When the Russians leave in 2020 ISS will lack some crucial facilities that it now depends on, and will require some fast scrambling and additions to the station by NASA to keep it going at that point.

Alternative rockets and 2015 launch dates for Cygnus

8:54 am

The heat of competition: Orbital Sciences has pinpointed available launch slots and alternative rockets for getting Cygnus into orbit in 2015.

[Orbital CEO David] Thompson said Wednesday the company has narrowed its options to three launch providers which have openings as early as the second quarter — between April 1 and June 30 — of next year. Two of the launch providers are based in the United States. Orbital could also launch Cygnus missions with a European-based company, Thompson said. The contractors under consideration are presumably United Launch Alliance, SpaceX and Arianespace.

Unlike Virgin Galactic’s claims in my previous post, I find Thompson’s prediction here quite likely. His main problem is not technical but political. He has to convince his competitors to help him, and this story is his first shot across the bow in that negotiation. By making these facts public, Thompson applies pressure on these other companies to agree. And though the request is unstated, he is also enlisting NASA’s aid, since the agency is certain to back him in this negotiation and apply its clout in his favor.

Turbopump failure in first stage engine eyed for the Antares launch failure

8:14 am

The investigation into the launch failure of the Antares rocket one week ago is now focusing on the turbopump in one of the rocket’s first stage engines.

“The Investigation Board (AIB) is making good progress in determining the primary cause of last week’s failure. A preliminary review of telemetry and video data has been conducted and substantial debris from the Antares rocket and its Cygnus payload has been collected and examined,” noted Orbital on Wednesday. “While the work of the AIB continues, preliminary evidence and analysis conducted to date points to a probable turbopump-related failure in one of the two Aerojet Rocketdyne AJ26 stage one main engines. As a result, the use of these engines for the Antares vehicle likely will be discontinued.”

It was later noted that the AJ-26 could still be used if they were proven to be completely flight-worthy.

If Orbital Sciences decides to completely cease using the Russian engines, it could mean a very significant delay before they can launch again, maybe several years. If they do that, I expect them to face contract penalties from NASA for the failure to deliver cargo to ISS on a reasonable schedule. It will also mean that their chances of winning a second contract will go down significantly.

They need to replace the engine, but they also need to keep launching. The article as well as a company press release today describes how they are exploring other launch vehicles, including the Falcon 9, to launch Cygnus, but I see no reason for them to completely abandon the Russian engines immediately. What they need to do is find what failed, fix it in the remaining engines, and keep flying while they scramble hard to replace the engine entirely.

Initial assessement of Wallops launchpad completed

6:00 pm

The investigation into the Antares launch failure has completed its initial assessment of the launchpad.

More here. Overall, the pad’s condition sounds better than expected. To quote the Orbital press release at the first link above,

The overall findings indicate the major elements of the launch complex infrastructure, such as the pad and fuel tanks, avoided serious damage, although some repairs will be necessary. However, until the facility is inspected in greater detail in the coming days, the full extent of necessary repairs or how long they will take to accomplish will not be known.

The image at the second link above shows some of the damage, none of which looks devastating.

Lawsuit could delay Cygnus cargo flight in April

7:20 pm

A lawsuit between Orbital Sciences and one of its subcontractors threatens to delay the planned April launch of Antares/Cygnus to ISS.

The lawsuit, filed Oct. 21 with the U.S. District Court for the Eastern District of Virginia, centers around a roughly $2 million contract Orbital Sciences awarded in 2013 to defendants Integrated Systems and Machinery of Smithtown, New York, and its owner, Kevin Huber. The contract called for Huber’s company to build new gimbals and cylinders for the hydraulic system used by the slow-moving, truck-like Transporter Erector vehicle that hauls Orbital’s Antares cargo rocket and Cygnus space freighter out of their Wallops Island, Virginia, hangar and raises them vertical at their Mid-Atlantic Regional Spaceport launch pad over a kilometer away.

Orbital’s third cargo run to the ISS — which at press time was still slated to launch Oct. 27 — can proceed without the withheld hardware. However, Orbital is obligated under an agreement with the Mid-Atlantic Regional Spaceport’s host state to upgrade the Transporter Erector before launching its fourth contracted cargo run, the debut of a bigger, heavier Cygnus cargo tug.

I don’t really expect this dispute to delay the April launch. What we have here is a case of hardball negotiations, with the subcontractor using the situation to try to squeeze more money out of Orbital Sciences. In the end they will come to an agreement and the upgrade will be installed.

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.

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.

A decision in November on Orbital’s reliance on Russian engines in Antares

9:38 am

The competition heats up: Orbital Sciences has announced that it will make a decision in November on replacing the Russian rocket engine that it uses in its Antares commercial rocket.

In a presentation at the 65th International Astronautical Congress here, Orbital Executive Vice President Frank Culbertson said the engine decision is linked to the company’s proposal for NASA’s Commercial Resupply Services (CRS)2 competition. NASA issued the request for proposals for CRS2 on Sept. 26, with responses due Nov. 14. “We’ll make sure we’ll have a decision on that before we submit the proposal,” Culbertson said when asked about the status of the engine decision.

Orbital has been weighing for several months a replacement for the AJ-26 engines that Antares currently uses. Those engines, provided by Aerojet Rocketdyne, are refurbished versions of Soviet-era NK-33 engines originally designed for the N-1 lunar rocket developed in the 1960s.

The company is considering several proposals, including one from ATK, which is in the process of merging with Orbital at this very moment.

The article also notes that Orbital recognizes that the use of Russian engines will likely work against them in the competition to win the next ISS cargo contract, and that if they don’t have a plan to replace those engines it is quite possible that NASA will go with a different company, such as Sierra Nevada, when it awards that contract.

As I said already, oh how I love competition.

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.

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.

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.

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.
