“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.

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.

Curiosity is out of safe mode and will be resuming full science operations by next week.

It is imperative that the engineers clear up these computer problems now, as communications with the rover will be limited in April because the sun will be in the way.

Transmissions from Earth to the orbiters [Mars Odyssey and Mars Reconnaissance Orbiter] will be suspended while Mars and the sun are two degrees or less apart in the sky, from April 9 to 26, with restricted commanding during additional days before and after. Both orbiters will continue science observations on a reduced basis compared to usual operations. Both will receive and record data from the rovers. Odyssey will continue transmissions Earthward throughout April, although engineers anticipate some data dropouts, and the recorded data will be retransmitted later.

The Mars Reconnaissance Orbiter will go into a record-only mode on April 4. “For the entire conjunction period, we’ll just be storing data on board,” said Deputy Mission Manager Reid Thomas of JPL. He anticipates that the orbiter could have about 40 gigabits of data from its own science instruments and about 12 gigabits of data from Curiosity accumulated for sending to Earth around May 1.

NASA’s Mars Exploration Rover Opportunity is approaching its fifth solar conjunction. Its team will send no commands between April 9 and April 26. The rover will continue science activities using a long-term set of commands to be sent beforehand.

ILS, the company that launches the Russian Proton rocket, has lowered its prices.

The competition heats up: ILS, the company that launches the Russian Proton rocket, has lowered its prices.

The reason they have given is that the insurance rates to use their rocket have risen due to the three Proton rocket failures in the past two years and that they want to offset that cost for their customers. I suspect a second reason is the price pressure that the Falcon 9 is placing on them.
