Next Falcon 9 launch set for Monday

8:56 am

The competition heats up: The next commercial Falcon 9 launch is now set for tonight, Monday, less than two weeks after the last Falcon 9 launch.

The next two weeks will be especially busy for SpaceX, as they also have scheduled the first launch abort test of Dragon on May 5. The launch will also be the fifth for Falcon 9 this year, putting it in the lead as the busiest rocket in the world for 2015, ahead of the Russian Soyuz.

Russians cancel effort to fly humans from Vostochny by 2019

8:51 am

The heat of competition? In order to meet a government deadline to launch humans from their new spaceport at Vostochny, the Russians had planned, though now cancelled, a single manned launch there in 2019, using a new rocket.

Their cancelled plans had included two prior test flights of the rocket with Progress freighters.

If cargo missions were successful, the one brave crew would ride into orbit from the new spaceport, knowing that in case of a serious problem with the rocket, the descent module of the spacecraft would parachute into deep forest of the Russian Far East or somewhere in the Pacific.

After “satisfying” this political goal with a single crew, all manned Soyuz and cargo Progress missions would then revert back to Baikonur for a safe ascent trajectory. The Soyuz spacecraft would continue flying two missions annually from Baikonur, until the veteran spacecraft’s final launch in 2025. In 2021, Soyuz spacecraft missions originating from Baikonur would switch from Soyuz-FG to Soyuz-2-1a rocket.

The Russians have now decided, rather than rush this first flight on the new rocket, to hold to the slower schedule.

This story is important to the United States. I think we must definitely end our dependence on the Russians before they make the switch to the new rocket. Based on the levels of poor quality control and corruption seen recently in Russia, I have grave doubts the new rocket will fly reliably at first. It would be a mistake to buy its use to put Americans in space.

Seven big failed environmentalist predictions

3:49 pm

Link here.

Like the author, I remember every single one of these doomsday predictions. I also remember how every single one of these predictions was wildly wrong. Until these fear-mongers can reliably predict things, I see no reason to believe them.

His article however does provide one entertaining tidbit:

You know how old I am? I’m so positively ancient that I remember when one of Jimmy Carter’s big answers to the impending shortage of oil was to increase federal funding for research on how to extract oil from shale. It ended the way you would expect: it went nowhere. But some decades later, private oil companies did find a way to more economically extract oil from shale—and environmentalists promptly made it public enemy #1.

All true. And just one more example of how the government fails at something while private enterprise, fueled by the profit motive, finds a way to make that exact same thing happen.

New Shepard test flights to begin within weeks

8:21 am

The competition heats up: Blue Origin is expected to begin regular test flights of its suborbital resusable manned spacecraft, New Shepard, within mere weeks.

This news came from a government FAA official involved in approving flight permits. The company itself has declined to comment.

Even if it is a few months rather than weeks, these flight tests will put more pressure on Virgin Galactic in the race to become the first commercial suborbital tourism company to sell and actually fly a passenger. And if I had to bet who’d win the race, I would no longer put my money on Virgin Galactic.

NASA ISS cargo contracts delayed

8:15 am

The competition heats up: NASA has delayed, for the second time, when it will award its next round of cargo contracts to ISS, pushing the date back from June to September.

Though agency officials said they could not reveal why they had delayed the contract awards, they did say it was to gather more information. My guess is that the agency wants to see how SpaceX’s launch abort tests turn out this year before it makes a decision. If successful, they will then have the option of dropping SpaceX’s as a cargo carrier and pick someone else, possibly Dream Chaser, to provide up and down service to ISS. That way, they would increase the number of vehicles capable of bringing people and supplies up to ISS.

Delaying the award decision until September gives them time to evaluate the abort tests results, as well as give them a cushion in case those tests get delayed somewhat.

Japan to the moon!

8:54 am

The competition heats up: Japan’s space agency has announced plans to send an unmanned lander to the Moon, as early as 2018, as part of a longer range plan to explore Mars.

They also intend to use their new Epsilon rocket to launch it.

Gee, I wonder if the successful efforts of India and China to send probes to both the Moon and Mars had some influence on this decision.

Incorrectly built SLS welding machine to be rebuilt

9:16 am

You can’t make this stuff up. A giant welding machine, built for NASA’s multi-billion dollar Space Launch System (SLS), needs to be rebuilt because the contractor failed to reinforce the floor, as required, prior to construction.

Sweden’s ESAB Welding & Cutting, which has its North American headquarters in Florence, South Carolina, built the the roughly 50-meter tall Vertical Assembly Center as a subcontractor to SLS contractor Boeing at NASA’s Michoud Assembly Facility in New Orleans.

ESAB was supposed to reinforce Michoud’s floor before installing the welding tool, but did not, NASA SLS Program Manager Todd May told SpaceNews after an April 15 panel session during the 31st Space Symposium here. As a result, the enormous machine leaned ever so slightly, cocking the rails that guide massive rings used to lift parts of the 8.4-meter-diameter SLS stages The rings wound up 0.06 degrees out of alignment, which may not sound like much, “but when you’re talking about something that’s 217 feet [66.14 meters] tall, that adds up,” May said.

Asked why ESAB did not reinforce the foundation as it was supposed to, May said only it was a result of “a miscommunication between two [Boeing] subcontractors and ESAB.”

How everyone at NASA, Boeing, and ESAB could have forgotten to do the reinforcing, even though it was specified in the contract, baffles me. It also suggests that the quality control in the SLS rocket program has some serious problems.

Update: The original story at Space News that I originally linked to disappeared sometime in the next week, and was replaced with a slightly more detailed and more positive story, now linked above.

Sierra Nevada and Germany sign agreement

9:00 am

The competition heats up: Sierra Nevada has signed a new development agreement with Germany in connection with its Dream Chaser reusable mini-shuttle.

The agreement does not appear to involve any money and thus is largely symbolic. Nonetheless, it shows again that Germany is interested in having Dream Chaser built, and is throwing its support behind the manned spacecraft.

SpaceX is considering a ground landing for its next first stage return attempt

9:08 am

The competition heats up: After its second attempt this week to land its first stage on a barge in the Atlantic, SpaceX is now considering landing their next attempt on the ground.

This shouldn’t be a surprise. The reason they have been landing over the ocean in these initial tests was for safety. The last two landings however had demonstrated that they can reliably bring that first stage back accurately and precisely. Since they have the ability to destroy the stage should it go off course, it seems reasonable to shift to land now and simplify their challenge.

Stratolaunch considers multiple rockets for its giant airplane

8:56 am

The competition heats up: Stratolaunch is now considering widening its options for the upper stage that can be attached to its giant airplane.

[Chuck Beames, president of Seattle-based Vulcan Aerospace, the parent company of Stratolaunch Systems] said the interest in alternative launch options is driven by the growing interest in small satellites, for which the current Stratolaunch system is oversized. A smaller vehicle, he said, could be developed more quickly and less expensively. “It takes a more near-term focus on revenue generation,” he said.

Stratolaunch could eventually support several launch vehicles, he said, with varying payload capabilities to serve different customers. “We’ll likely have multiple launch vehicle options,” he said. “Some will be available earlier than others.”

It appears they are revising their launch system airplane into a modular design with a variety of upper stages, depending on customer. Note also the focus on the growing small satellite industry.

An engineering analysis of the Falcon 9 first stage landing failure

8:44 am

Link here.

SpaceX founder and chief technology officer Elon Musk tweeted that “excess lateral velocity caused it [the booster] to tip over post landing.” In a later tweet that was subsequently withdrawn, Musk then indicated that “the issue was stiction in the biprop throttle valve, resulting in control system phase lag.” In this statement, Musk was referring to “stiction” — or static friction — in the valve controlling the throttling of the engine. The friction appears to have momentarily slowed the response of the engine, causing the control system to command more of an extreme reaction from the propulsion system than was required. As a result, the control system entered a form of hysteresis, a condition in which the control response lags behind changes in the effect causing it.

Despite the failure of the latest attempt, SpaceX will be encouraged by the landing accuracy of the Falcon 9 and the bigger-picture success of its guidance, navigation and control (GNC) system in bringing the booster back to the drone ship. The GNC also worked as designed during the prior landing attempt in January, which ended in the destruction of the vehicle following a hard touchdown on the edge of the platform.

Why SpaceX’s first stage failure is really a magnificent success

9:48 am

Yesterday SpaceX attempted for the second time to land the first stage of its Falcon 9 rocket on an unmanned barge in the Atlantic. They failed, spectacularly.

I however consider this attempt to be a magnificent success. I also think they could fail at achieving this vertical landing for the next twenty launches and still those failures would each be a magnificent success.

Why? How can an engineering failure like this really be considered an achievement? It is very simple. Even if SpaceX continues to fail in its effort to recover its Falcon 9 first stage and reuse it, the possibility that they might succeed — demonstrated time after time by the company with each launch — has struck terror in the hearts of every other aerospace launch company. Each landing attempt shows SpaceX’s commitment to lowering launch costs while developing cutting edge engineering capabilities. Each attempt shows the world that they are the world’s leading launch company.

The result? Every other launch company in the world, both old and new, are scrambling desperately to lower their own costs as well as improve their own engineering.

Another successful Dragon/Falcon 9 launch

1:16 pm

The competition heats up: SpaceX has successfully launched another Dragon freighter to ISS.

We await word on whether the first stage was able to successfully land vertically on a barge in the Atlantic.

Update: Musk reports that the first stage landed on the barge but “too hard for survival.” Expect some interesting video to follow. I have posted SpaceX’s video of the launch below the fold. Beginning at about 22:45, after first stage separation, you can see it maintain a vertical orientation as it begins its descent.

Stratolaunch update

8:48 am

This article about Paul Allen’s Stratolaunch company notes that the payload the system will put in orbit is likely to be less than originally hoped.

Still to be determined are the manned and cargo craft Stratolaunch will eventually send to orbit or even the International Space Station, Beames said. Musk’s SpaceX, an initial partner, is no longer associated with the venture. The rocket produced by Orbital ATK Inc., which replaced SpaceX, will probably be smaller than the medium-lift vehicle with a 6,000 kilogram (13,000-pound) payload that Stratolaunch had initially planned, Beames said. “I think it’s more likely we’ll be targeting a smaller payload class,” Beames said. “We’re not announcing anything on that yet.”

Allen’s company, Vulcan Aerospace, is also demanding that ULA change the name of its new Vulcan rocket, just revealed yesterday.

ULA has dubbed its next generation rocket Vulcan

1:59 pm

ULA has announced its plans for replacing the Delta and Atlas 5 rockets, dubbing its new rocket Vulcan.

They plan to develop Vulcan’s first stage first and use it initially on Atlas 5 rockets so they can replace the Atlas 5 Russian engines as soon as possible. Also, they plan to recover the Vulcan rocket’s engines by having them separate from the booster after use and then get captured in a mid-air before hitting the ground. (See the graphic at the link to see a launch profile.)

In watching the press conference, ULA officials made it very clear that they are focusing a lot of their effort on lowering the cost of the rocket.

Tank tests for launch abort rocket

9:27 am

The competition heats up: This week SpaceX conducted at Vandenberg a tank test of the booster rocket that will be used for its Dragon in-flight launch abort test later this year.

That they are doing these tank tests at Vandenberg is interesting. I would think the actual abort test would take place at Kennedy, where astronauts will be launched. Either the company is taking advantage of its second launchpad to save time while Kennedy is in use for Monday’s Dragon launch, or they will actually do this launch abort test out west. In truth the test can be done from Vandenberg. The flight path will be different, but the technical requirements will be essentially the same.

Note that this booster is for the in-flight launch abort flight, scheduled at this moment for July, not the launchpad abort test, scheduled at this moment for May 2.

Also, it is interesting to compare the pictures of SpaceX’s Vandenberg launchpad in this article with the pictures I took when I visited Vandenberg two weeks ago. Then, the pad was quiet, with no rocket visible (though it is likely that this booster stage was inside the building being prepared). Now it is quite busy.

Cubesat satellite industry booming

9:03 am

The competition heats up: In 2014 more cubesats were launched than during the industry’s first ten years.

Without doubt the concept of cubesats is now taking the satellite industry by storm, mainly because of the advent of new electronic miniaturization. However, the most fascination part of this story was how the concept was born:

In 1999, Puig-Suari met with Bob Twiggs, at the time an aerospace engineer at Stanford University, to discuss ways of getting more student projects into space. “We had to do something to get more opportunities to launch these things,” recalls Twiggs, now at Morehead State University in Kentucky. They focused on slimming down the spacecraft, because weight drives up the cost of reaching orbit.

Over lunch at a sandwich shop in San Luis Obispo, Twiggs and Puig-Suari sketched out options on a napkin. They thought hard about the potential capabilities of a 10-centimeter cube with a mass limit of 1 kilogram—the size and weight of a liter of water. Clad in solar cells, the cube would eke out perhaps a watt of power, enough to power a small computer and a radio: “a Sputnik,” Puig-Suari says. Back at Stanford, Twiggs found the perfect life-size demonstration model: a plastic box used for storing the insanely popular stuffed animals known as Beanie Babies. A standard was born.

Read the whole thing. The low cost of these tiny satellites is about to revolutionize the entire unmanned space industry.

SpaceX to try a first stage recovery again on April 13

8:52 am

The competition heats up: In its next launch on Monday, SpaceX will once again try to safely land its first stage on an ocean barge, allowing it to reuse that stage on later flights.

Monday afternoon is certainly going to be an exciting day for space cadets. First, at 4 pm (Eastern) the head of ULA will reveal the design of that company’s new rocket. Then, at 4:33 pm (Eastern), SpaceX will launch Dragon to ISS while attempting to return the first stage safely.

Airbus Safran demands full ownership of Ariane 6

5:15 pm

The competition heats up: One of the heads of Airbus Safran that is offering to build Europe’s next rocket, Ariane 6, has said that they must have full control of the rocket and project or they won’t do it.

“We are now a few weeks from the submission of a bid, and of course at this stage everyone defends his camp,” Lahoud said. “It is said that industry needs to make a financial contribution. We have said it’s possible we will contribute, but on condition that [development] not be conducted under the former system.

“We want responsibility for the design, the production, the commercialization and operations to be in the hands of industry, and not in a sort of mixed-economy creation that borrows more from the United Nations than from what our competitors do. Under these circumstances, and only under these circumstances, will there be a business case that allows us to invest, and to defend before our boards of directors the fact that corporate cash needs to be spent.”

In other words, they will not build something that will be under the complex bureaucratic control of the many-headed European Space Agency. Under that framework, they don’t think they can compete, so why bother?
