Google tells a major conservative website to take a hike.
It sure appears that Google has cut the website off for political reasons.
Building a scale model of the International Space Station — using matchsticks!
Recently completed by Acton, the wooden ISS is as impressive in size as it is in detail. Comprised of 282,000 matchsticks, the 1/26 scale model required 8 gal (30 L) of glue and took roughly 1,950 hours to complete. Whereas the actual ISS measures out at 108.5 m (356 ft) wide and 72.8 m (239 ft) long, Acton’s scaled down version measures out at an impressive 4.1 m (13.5 ft) and 2.8 m (9.2 ft) wide. Solar arrays, trusses, communication components, and even the Space Shuttle Atlantis, are all there in intricate detail.
With pictures.
Fact checking Elon Musk’s statements about his company’s efforts to reuse the Falcon 9 first stage reminds us of some space history and one of Musk’s chief competitors.
The bottom line: Bringing the first stage back to Earth safely and vertically is doable, and has been done before.
Because of issues preventing a dress rehearsal countdown and launchpad static fire of the Falcon 9 rocket SpaceX has delayed Saturday’s launch.
No new date has yet been set, but I expect the delay will not be long.
Ten modern conveniences we take for granted that didn’t exist before 1970.
I especially like the picture of the audio cassette and the pencil with the caption, “Our children will never know the link between the two.”
How to turn an American spacecraft ferrying astronauts to ISS serve as a lifeboat as well.
A very interesting read, as it outlines the specific technical problems faced by engineers that one wouldn’t normally consider. The capsule has to be able to remain functional and reliable after months in orbit, but it also has to become functional at a moment’s notice, should an emergency happen.
The competition heats up: SpaceX’s next Falcon 9 commercial launch, set for early Saturday morning, will once again attempt a soft splashdown of its first stage.
If this launch happens as scheduled it will also be the fastest turn-around between launches for the company.
The sanctions against Russia imposed by the Obama administration could delay the launch of Iridium’s second generation communications constellation of satellites.
The competition heats up: SpaceX continues to acquire land in Texas for its planned spaceport in Brownsville.
Elon Musk’s Dogleg Park LLC picked up an additional five lots in late April, bringing the total number of lots it has acquired in Cameron County to 95. The total land area that SpaceX now owns is roughly 38 acres of land, public records show. This is in addition to 56.5 acres that SpaceX has under lease at the site of what would be the world’s first private and commercial vertical launch site.
Compared to the acquisitions made by the federal government when it established its space centers in Florida and Wallops Island, these purchases are small. Nonetheless, they are likely sufficient for what the company plans to do.
The competition heats up: SpaceX releases spectacular footage of another vertical take-off and landing test of their Falcon 9R rocket, this time flying over 3,000 feet in the air.
Video below the fold. What I think everyone, including me, has missed so far about both the Grasshopper and the Falcon 9R test flights is that the test vehicle not only was able to land safely using its rockets, both vehicles were quickly turned around and flown again. This certainly lends weight to the feasibility of the company’s plan to make their first stage reusable.
A draft bill in Congress is proposing the Pentagon develop an engine for the Atlas 5 engine to replace the Russian engine now used.
The legislation passed by a House subcommittee Wednesday calls for up the U.S. military to spend up to $220 million next year to kick off full-scale development of the engine, which could be ready for flights no later than 2019. The bill states the Defense Department “should develop a next-generation liquid rocket engine that is made in the United States, meets the requirements of the national security space community, is developed by not later than 2019, is developed using full and open competition, and is available for purchase by all space launch providers of the United States.”
There is no reason for this funding gift to the aerospace industry. For one thing, there are two rockets that already exist that use all U.S. parts, the Delta family of rockets and the Falcon 9. For another, if Congress stays out, the private sector will take care of this need and do it for a lot less and far quicker, while costing the taxpayers relatively little. By making this a government project we guarantee it will be expensive and take forever, thus keeping the pork flowing to Congressional districts without solving the problem.
And speaking of keeping pork flowing to Congressional districts, pork king Senator Richard Shelby (R-Alabama) today ripped into NASA for trying to trim a little from the budget of SLS (which sends a lot of cash to Alabama). He also condemned NASA’s manned commercial effort.

Guns or rockets: Which part of the ATK split is the stronger?
The competition heats up: Boeing and Bigelow show off their respective manned capsule and space station module. More here.
The images of Bigelow’s mock-up of its BA-330 space module are what is especially interesting, considering that we have seen similar mock-ups already of the interior of Boeing’s CST-100 capsule.
A gigantic forest fire threatens Russia’s new spaceport under construction in Vostochny.
[Spaceport construction chief Konstantin] Chmarov reportedly characterized the fire-fighting effort in the region as “chaos.” Fueled by hot weather and strong winds, the fire approached the airport in Svobodny and was also moving toward Vostochny. In the meantime, satellite images showed heavy smoke blanketing the future space center.
The Putin government has been giving the completion of this spaceport a high priority. Having it burn down before completion is not what they want.
SpaceX has won an injunction from a federal judge, preventing ULA from buying any further Russian engines.
Federal Claims Court Judge Susan Braden said her preliminary injunction was warranted because of the possibility that United Launch Alliance’s purchase of Russian-made engines might run afoul of the sanctions. NBC News’ past coverage of the issue was cited in Braden’s ruling.
Wednesday’s injunction prohibits any future purchases or payments by the Air Force or United Launch Alliance to NPO Energomash, unless and until the Treasury Department or the Commerce Department determines that the deal doesn’t run counter to the U.S. sanctions against Russian officials. Braden stressed that her ruling does not affect previous payments to the Russians, or purchase orders that have already been placed. United Launch Alliance says it already has some of the engines on hand.
This injunction is not directed specifically at the Air Force’s bulk buy from ULA, nor does it address the cartel-like nature of the ULA monopoly for Air Force launches that SpaceX is challenging. However, it does put a serious crimp, if temporary, on the use of Lockheed Martin’s Atlas 5 rocket, which depends on the engine for all its launches. Though the company has engines in stock, they will quickly run out with no way to immediately replace them.
The competition heats up: Thaicom has chosen Orbital Sciences to build its next major communications satellite and SpaceX to launch it.
Thaicom used a Falcon 9 in January to launch its Thaicom 6 satellite, also built by Orbital Sciences. Apparently they were very satisfied with both companies.
Orbital Sciences is considering using ATK’s solid rocket motors to replace the refurbished Russian engines in the first stage of its Antares rocket.
This helps explain the merger between the two companies, as it gives Orbital control over the equipment it needs to keep Antares viable. More important, it also could make it entirely American made, which will be attractive to both Congress and many U.S. commercial satellite companies.
The competition heats up: Arianespace has successfully launched a commercial satellite with its new Vega rocket.
SpaceX has released video of its Falcon 9 first stage splashing down vertically in the ocean.
The video is not very good, but at one point you can clearly see for a flash that the first stage is vertical and appears to be hovering above the water.
For decades engineers and managers in the aerospace industry have said that returning a first stage vertically made no sense. Elon Musk insisted that SpaceX try. It appears he and his company are now going to prove that everyone else was wrong about this.
The competition cools? ATK is splitting off its aerospace division to merge that division with Orbital Sciences.
Alliant Techsystems Inc. ATK on Tuesday said it plans to split into two independent companies, one focused on outdoor sports and hunting products, the other centered on aerospace and defense. The outdoor sports operations–which produce commercial ammunition, hunting products and other related items–will be spun off to Alliant shareholders in a tax-free transaction, the company said. The segment generated $2.2 billion in revenue during 2013, Alliant said.
After the separation, Alliant said it plans to merge the aerospace and defense business–which produces rocket propulsion systems and satellite systems, among other things–with rocket and space-system developer Orbital Sciences Inc. The company will be named Orbital ATK Inc.
More here. The company press releases call this “a merger of equals” and do not make it clear what instigated the deal. Did Orbital offer to buy ATK’s aerospace division with its ammo business spun off, or did ATK want to sell off its aerospace division to focus on ammo? I wonder. The ammo business right now is booming, while aerospace remains a much more risky venture. ATK might have wanted to focus on ammo, where the money is, and proposed the idea to Orbital.
Arianespace today scrubbed the third launch of its new Vega rocket at T-minus 10 minutes due to a technical problem.
The reliability of Arianespace’s rockets has always been the company’s big selling point, so a launch scrub is very unusual for them. Then again, this is only the third launch of Vega, so we shouldn’t be surprised if they are still working out the kinks.
A proposed House bill would forbid use of Russian rocket engines in launching any American military payloads.
This bill is being put forth partly because of the Ukrainian situation and partly to support SpaceX’s effort to break the ULA Atlas/Delta monopoly on military launches. Whether it makes any sense or not is of course beside the point.
Meanwhile, the State Department has expanded the sanctions on satellite exports to Russia, which might threaten some future commercial Proton launches.
Both actions suggest that Elon Musk’s political clout is growing. Obviously his company’s concerns are not the prime motivation behind these decisions, but we should note that both actions hurt his direct competitors, while doing little harm to SpaceX.
The competition heats up: ULA has accelerated delivery of its required Russian rocket engines in anticipation of worsening relations with Russia and with members of Congress.
ULA presently is the only company the Air Force uses to launch its military satellites, and members of Congress are questioning this monopoly in the context of the situation in the Ukraine as well as SpaceX’s lawsuit challenging it.
The competition heats up: Russia’s Proton rocket successfully put two satellites into orbit on Monday.
This is the first of a slew of Proton launches in the next few months as they work to catch up on their launch manifest.
At the end of a press conference Elon Musk lets slip the news that SpaceX has chosen Brownsville, Texas as the location of its commercial spaceport.
They still have to get some FAA and environmental approvals, but expect to be launching from Texas in “a couple of years.”
SpaceX sues to block ULA’s monopoly on Air Force military launches.

The competition heats up: Orbital Sciences intends to use an upgraded Antares rocket as its contribution to Stratolaunch.
Part of the upgrades appear to be making sure Antares has an available replacement engine for the refurbished Soviet-era engines Antares is now using.
The competition heats up: SpaceX has signed a deal to have its new Raptor engine tested at NASA’s Stennis Space Center.
This is a good use of these government facilities, providing a service and also making money for the government.
Surprise, surprise! Russia has noticed literally no change in cooperation with NASA since the U.S. government announced two weeks ago that all such cooperation, excluding ISS, was being cut off.
Russia’s Roscosmos space agency has yet received no official notifications from NASA on curtailing cooperation, and working contacts continue, Roscosmos chief Oleg Ostapenko said in an interview with Vedomosti newspaper Wednesday. “Roscosmos has received no official notifications on suspending cooperation, we continue working contacts with NASA and other space agencies,” Ostapenko told Vedomosti adding: “Recently I held talks with the NASA leadership and European colleagues.”

I had said that so-called NASA cut-off was all show and aimed not at Russia but at Congressional budget negotiations over NASA’s commercial crew program. This story only proves it.
