At the AIAA meeting this week in Pasadena, NASA officials admitted that the Space Launch System (SLS) will likely cost half a billion dollars per launch
It’s only money! At the AIAA meeting this week in Pasadena, NASA officials admitted that the Space Launch System (SLS) will likely cost half a billion dollars per launch.
That means that after only two flights this rocket will have cost about the same as the entire manned commercial program, from which three different space companies are building three different methods for getting humans into space. After three missions it will cost more, and after four missions it will have cost double. And this is assuming that the half billion dollar “target” number ends up correct.
We can’t afford this. We never could, which is why the Saturn 5 rocket was abandoned, and why the shuttle never fulfilled its stated goal of lowering the cost of access to space and after thirty years was abandoned as well. Instead, we have got to find a cheaper way to do this, and to my mind, competition and private enterprise is the only hope.

A dispute over launch pricing between ArianeSpace, the launch company, and Globalstar, the satellite company.
A dispute over launch pricing between Arianespace, the launch company, and Globalstar, the satellite company.
The article only quotes an executive from Arianespace, who suggests Globalstar has been having troubles making payments. I wonder instead if maybe Globalstar has been balking at Arianespace’s prices (knowing there are other companies that can do it cheaper) and has been holding out for a price cut.

An experimental vertical take-off and landing rocket crashed during its most recent test on Tuesday.
An experimental vertical take-off and landing rocket crashed during its most recent test flight on Tuesday.
The Xaero had already flown more than 100 test flights, so this crash does not make it a failure. Like all engineering tests, the flight will only be a failure if they cannot figure out what went wrong.
This update says they have located the problem, the failure of a valve.

Whiskey in space?
Whiskey in space? Not really, just some chemicals taken from a distillery up to ISS to test the effects of gravity on “the maturation process.”
Nonetheless, the distillery has issued a limited edition whiskey to celebrate the experiment.

The Russian space agency has ordered the recall and inspection of every Briz-M upper stage used in their Proton rocket.
The Russian space agency has ordered the recall and inspection of every Briz-M upper stage used in their Proton rocket.
This is part of the on-going shake-up of the Russian rocket industry following the recent failures of the upper stage during several commercial launches. One interesting and positive note is that they expect to resume launches in October, which is extremely fast.

Three super weird homes
India’s space agency celebrated its 100th launch today.
The competition heats up: India’s space agency celebrated its 100th launch today.
It is unclear whether the numbers include their failed launches. Regardless, India has a vibrant space program, modeled somewhat after the Russian system, a government space agency focused on gaining commercial market share. Whether that model can successfully compete in the commercial world remains unknown. Russia has had success, but only during a period when they were faced with few competitors. Now that the competition is heating up it is unclear whether Russia’s model will be flexible enough to compete.
What is clear about India, however, is that they are passionate about space exploration. Historically, even the Russian government model has worked when the country using it was the new kid on the block.

Sign the LunarCOTS petition.
Do you think the commercial space program led by SpaceX is the fastest and cheapest way for the U.S. to get humans back into low Earth orbit? Then why not do it for missions beyond Earth orbit?
The LunarCOTS petition is a campaign to have NASA subsidize private companies to design and build the United States’ future interplanetary missions rather than have NASA do it in big government programs like SLS. Makes sense to me, and so I signed the petition immediately.

Sounds great, but Clark Lindsey has a very informative review of the history of these announcements from Russia, none of which has ever born fruit.

The Forest Products Laboratory of the U.S. Forest Service has opened a $1.7 million pilot plant for the production of cellulose nanocrystals, which have the potential to be stronger, stiffer, and lighter than Kevlar or carbon fibers.
The Forest Products Laboratory of the U.S. Forest Service has opened a $1.7 million pilot plant for the production of cellulose nanocrystals, which have the potential to be stronger, stiffer, and lighter than Kevlar or carbon fibers.
It appears that the lab has been researching the useful properties of these nanocrystals, which is a good thing. However, I can’t help wondering why they are now building a production plant. Shouldn’t this be left to the private sector? What business is it of the Forest Service to be a producer of this product? It could be that the plant is aimed not at production but at figuring out how to make it affordable and practical, a goal that might make sense for a government agency to pursue. If not, however, it seems inappropriate for a government agency to use taxpayer dollars to run a facility aimed at selling a product to the private sector.
The article, as well as the lab’s webpage, do not make this clear.
