First test flight of Angara is officially postponed

9:10 pm

It’s official: The first flight of Angara has been postponed for at least a week or more.

“The rocket will be removed from the launchpad and transferred to a technical stand for comprehensive analysis,” RIA quoted the Khrunichev center as saying, adding the new launch time would only be decided after the checks.

Though no information was released that describes the cause of the scrub, that they are going to give the rocket a major look-over suggests that at least one of the problems reported by Anthony Zak at Russianspaceweb are likely true. To quote him again:

According to a veteran of Baikonur Cosmodrome and the Russian space historian Vladimir Antipov, the scrub at that moment could indicate a failure in the pneumatic and hydraulic system activating the rocket’s propulsion system. A screenshot of the launch countdown clock, which had surfaced on the Internet, indicated a scrub at T-1 minute 19.7 seconds. It then transpired that the loss of pressure in a flexible gas line of the propulsion system caused the delay.

It could take as long as a week to fix the problem, industry sources said on the Novosti Kosmonavtiki web forum. GKNPTs Khrunichev, the Angara’s manufacturer then posted a one-line press-release saying that the date of the next launch attempt would be announced later.

According to other sources, a valve on the oxidizer line failed, which could require to return the rocket to the assembly building, to cut out the device and weld in the new valve. Due to a built-in nature of the valve, the return of the rocket to the manufacturing plant in Moscow could also be required, likely postponing the mission for weeks.

An contract extension from NASA for SpaceX and Sierra Nevada

3:18 pm

NASA has given SpaceX and Sierra Nevada six additional months, until March 2015, to complete their last contractual milestones for building their manned spacecraft.

An amendment signed by William Gerstenmaier, NASA’s associate administrator for human exploration and operations, on May 16 gives SpaceX until March 31, 2015, to complete the 14th and final milestone under its $440 million CCiCap agreement — a pad abort test of its Dragon capsule. The test originally was planned for April 2014.

On May 19, Gerstenmaier signed a similar amendment to Sierra Nevada’s $212.5 million CCiCap award to extend work associated with flight tests of the company’s Dream Chaser engineering test article until March 31, 2015.

NASA’s third Commercial Crew partner, Boeing, is on track to complete all its milestones, worth a combined $460 million, by the end of August,

The significance of this extension is that it reveals something about the dates for both SpaceX and Sierra Nevada’s next flight tests. The previously date for the pad abort test for Dragon had most recently been set for this summer. They are obviously not meeting that schedule and need more time. Sierra Nevada meanwhile wants to fly its Dream Chaser test vehicle some more, but apparently needs time to get it flight ready after it sustained damage during landing on its one and only flight test.

In addition, this extension suggests something about NASA’s assessment of the efforts of all three companies. The agency is supposed to down select to two companies by the end of the summer. The extension suggests that they are hoping to keep all three companies funded so that they all build their spacecraft.

Angara launch scrubbed.

8:41 am

Only moments prior to launch computers aborted the first flight of Angara, Russia’s first new rocket since the Soviet-era.

More information here. According to a Russian web forum, the problem is probably a leaky valve or the loss of pressure in the propulsion system and that it might take a week to be fixed.

The quote below from the first story above is interesting in that it once again illustrates how Putin is trying to exert his authority over the space industry to re-establish the Soviet-era top down way of doing things:

Putin, who had been poised to watch the rocket’s inaugural flight from the northern military Plesetsk cosmodrome via video link from the Kremlin, ordered his generals to report on the cause of the delay within an hour.

Comparing the rocket vs balloon space tourism ride.

8:59 am

The competition heats up: Yahoo today published a 5 point comparison between a ride on Virgin Galactic’s SpaceShipTwo and Worldview’s Voyager balloon.

The winner, Virgin Galactic, but by a nose. As the story notes, Worldview is the better buy. “You can use the money you save for a nice vacation on Earth — where you can make new friends by telling stores about that time you went to space.”

China heads for the Moon and Mars.

8:43 am

The competition heats up: In several different news stories today China touted its future plans in space.

The landing test described in the first story above will also be the first test flight of China’s new heavy lift rocket, Long March 5.

That China is both politically and culturally serious about this effort can be seen by the nationalistic enthusiasm for this space effort that permeates these stories. They also can’t help comparing their plans to U.S. efforts.

Arianespace lowers its prices.

8:44 pm

The competition heats up: In an effort to compete with SpaceX, Arianespace has lowered the price it charges for launching smaller satellites on its Ariane 5 rocket.

According to Stephen Israel, the company’s CEO, the lower prices have already produced some contracts. However, the company has not been able to institute comparable cost savings in its operations, which means it

…will force the European launch supplier to ask European governments this year for a 16 percent increase in annual support payments. In its 2013 annual report, Evry, France-based Arianespace said it will ask European Space Agency governments in December to allocate 116 million euros ($158 million) per year for the period between 2015 and 2018 to enable Arianespace to reach financial break-even. That figure compares to the current allocation of about 100 million euros per year for 2013 and 2014 that ESA governments approved in late 2012.

I wonder if the company will get these additional subsidies. In the past there were complaints from the European partners about the inability of Arianespace to make a profit. For it to lose even more money now will not make people happy.

I think, however, that Israel recognizes this. He has been pushing the organization to streamline its operation. Whether he can succeed against Arianespace’s entrenched pork-laden structure remains the big question.

Another update on the reactivation of ISEE-3

8:32 am

The private effort to reactivate this 1970s science probe continues.

They attempted today to fire the thrusters to spin up the spacecraft as required, but were forced to abort. The information gained however tells them that they should be able to do what is necessary, including two major engine burns on June 30 and July 2, to put the spacecraft into its new orbit.
