SpaceX’s first stage teaches them how to land on Mars

The competition heats up: This update on the status of SpaceX’s manned Dragon capsule also provides this interesting detail about the engineering knowledge gained from the company’s effort to vertically land its Falcon 9 first stages:

The company is also using the propulsive landings as a way to practically and physically test landing systems in a near-Mars atmospheric environment. “Earth’s upper atmosphere is also a really good analogue for Mars’ atmosphere,” noted [Garrett Reisman, Director of Space Operations]. “When you get up high enough, the density and consistency of the atmosphere is very similar to what you face during Entry, Descent, and Landing (EDL) on Mars. So every time we land, we take one of these rockets and we perform hypersonic retrograde propulsion, the data from which we’re sharing with JPL because it’s the first time this has ever been demonstrated on a major scale.”

To this end, Reisman pointed out that the Falcon 9 first stage landings are really serving as test beds for the EDL systems of eventual Mars missions. “Every time you see one of those rockets coming back, not only is it enabling a whole new paradigm for launching things into space, but it’s also bringing us one step closer to Mars.

As for Dragon, it now appears the company wants to do a full unmanned demo flight to and from ISS before it performs its launch abort test. They will then follow this with a manned demo mission to ISS. All three flights are planned for 2017.

Sierra Nevada prepares for Dream Chaser glide tests

The competition heats up: Sierra Nevada now expects to deliver its refurbished engineering test prototype of Dream Chaser to NASA for new glide tests in August.

“Our version of the shuttle Enterprise is about to be finished for its next phase of flight tests,” [said Mark Sirangelo, corporate vice president.] “Somewhere in the August time frame, it’s going to be shipped off to California, to the Armstrong [Flight Research] Center and to Edwards to be in Phase 2 of flight testing, which is going to be really fun and exciting.”

Sirangelo said lessons learned from the atmospheric flight tests will be applied to the development of the orbital test vehicle, which is now being outfitted in Colorado. That test vehicle, in turn, will blaze the trail for the spacecraft that will carry cargo for NASA under the CRS-2 contract. “We are looking to be launching on time, which is about three years from now, in the second half of 2019,” Sirangelo said.

They get this cargo version flying successfully, and they will certainly get a contract to build a manned version.

Russia in perspective

The coming dark age: This column today attempts to put the present economic shape of Russia into context with the rest of the world. Russia does not come off well.

According to the International Monetary Fund’s most recent data, the Russian economy is approximately the same size as Australia and slightly smaller than South Korea. As an exporter, it is now less important than Belgium, Mexico, and Singapore. And it is poor. The World Bank ranks Russia’s GDP per capita below Lithuania, Equatorial Guinea, and Kazakhstan. A larger proportion of its population lives below the poverty rate than in Indonesia, India, or Sri Lanka. It is ranked 67th in the world in the Global Competitive Index and 66th in the UN’s Human Development Index.

I find this news very disturbing and worrisome. As much as I might consider Russia a competitor to the U.S., I also want it as a nation to thrive, because otherwise it can only be a threat to the rest of the world. If Russia can’t figure out how to be a successful, competitive, and vigorous first world capitalist nation, it can only become something none of us will like. These are the same circumstances that made the rise of Hitler and Mussolini possible.

Unfortunately, I am not optimistic about Russia’s ability to turn things around. When they had the chance after the fall of the Soviet Union, instead of encouraging free competition, the people who remained in power divided the country and its industries up like Prohibition-era gangsters, and stamped out anyone who tried to move in on their territories with new ideas. Those people remain in power, and have acted to further consolidate their power by recreating the Soviet model of centralized control from the top-down.

Russia plans 12 person lunar base by 2030

The competition heats up? Russia has announced plans to build a 12-person lunar base by 2030.

Color me skeptical. Since the late 1990s I have been reading these stories about ambitious Russian space plans, none of which has ever happened. In fact, they all remind me of the dozens of ambitious space plans announced by NASA over the years, none of which ever happened either. Typical of big government projects, they end up on the scrapeheap because government can’t do things quickly or efficiently.

Damaged Falcon 9 first stage returns to port

The remains of the damaged Falcon 9 first stage that tipped over during its barge landing last week returned to port this past weekend.

Video and images of it can be seen at the link, all of which suggest that there is a slight chance the engines might be salvageable. Regardless, SpaceX once again has valuable used space hardware that no one else has ever had which it can study to improve its future rocket designs.

Russia’s continuing weakness in space

In the heat of competition: Russia this week announced new space agreements with both China and Europe.

The first describes a deal whereby Europe will pay Russia to use its Bion capsules to launch life science experiments. In addition, the article notes that Europe will continue its agreement with Russia to launch commercial Soyuz rockets from its Arianespace launchpad in French Guiana.

The second and third stories describe a variety of negotiations between Russia and China, whereby the two countries will work together in a number of ways, including the possibiliity that China will buy the same Russian rocket engine that ULA uses in its Atlas 5 rocket as well as maybe jointly build a heavy lift rocket with Russia. In the second article, Russia’s deputy prime minister Dmitry Rogozin, in touting the excellence of the Russian rocket engine, could not help taunting the United States.

Florida demands $15K port fee from SpaceX

Nice first stage you got there, be a shame if something happened to it: The Florida port where SpaceX has been offloading its recovered first stages from its barge has announced that it wants to charge the company $15,000 each time.

“We view their cargo passing over our dock just like any other cargo passing our dock,” Port Canaveral Chief Executive Officer John Murray said. “We’re not looking at this as an adversarial relationship. It’s no different than anything else coming across the dock. You have to pay for use of port facilities. That’s how a port makes its money.”

“The proposed wharfage fee is 14 times higher than what any other business is being charged for using port facilities,” SpaceX spokesman John Taylor said in an email to FLORIDA TODAY. “Port Canaveral is an important partner in our recovery operations. But we expect fees to be fair and reflect our actual use of the port. We’re looking forward to participating in the meeting later this week.”

The port notes that the size and the weight of the first stages cause significant wear and tear to the port, and thus should pay more. They have a point, but this still looks like they have noticed they have a customer with deep pockets that they now are trying to pick.
