“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”

“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”

I’m both glad and not surprised that some heavy hitters are beginning to say this. As I noted last year, as the commercial space program begins to show success the politics will increasingly favor it over the very expensive and not very productive NASA-built Space Launch System.

Be prepared for SLS to steadily lose political support in the coming years.

At a cave rescue course

Posting this weekend is light because I am attending a class here in Tucson on cave rescue. Today, Saturday, was a mostly in class session going over the basics, most of which I am very familiar with from many years of experience. We did spend ninety minutes learning how to carry people around in a sked or sled, two different types of equipment used to carry a patient through difficult cave passage. In this case the terrain was simulated by going up, over, under, and around scaffolding and vehicles inside a garage. Lots of fun.

On Sunday we will be doing a mock rescue, whereby we will arrive at a cave entrance where we will have to locate the patient in the cave and get that person out of the cave safely. Should be most interesting.

India has successfully tested a homebuilt engine to be used in its more powerful geosynchronous launch rocket, set for launch in July.

The competition heats up: India has successfully tested a homebuilt engine to be used in its more powerful geosynchronous launch rocket, set for launch in July. More here.

Previous launches of the GSLV rocket used a Russian-built engine on a second stage. They also ended in failure, not because of the Russian equipment but because of other problems.

Elon Musk confirms that on future Falcon 9 launches they will do tests of a powered return of the first stage.

The competition heats up: Elon Musk confirms that on future Falcon 9 launches they will do tests of a powered return of the first stage.

For the upcoming flight, after stage separation the first stage booster will do a burn to slow it down and then a second burn just before it reaches the water. In subsequent flights they will continue these over-water tests. He repeatedly emphasized that he expects several failures before they learn how to do it right. If all goes well with the over-water tests, they will fly back to launch site and land propulsively. He expects this could happen by mid-2014.

These tests are an extension of the Grasshopper tests, only this time they will take place during an actual launch.
