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.

Russian investigation begins on failed Soyuz solar array

5:55 pm

The Russians have established an investigation committee to look into the failure of a solar array to deploy during the most recent Soyuz manned launch.

They are also going to have the array inspected by Russian astronauts during a planned spacewalk in October. Still no word, however, on the capsule’s viability as a lifeboat for the next five months with one failed solar array.

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.
