Rider on the Storm

9:23 pm

Rider on the storm.

At approximately 6:00 pm, Lt Col Rankin concluded that his aircraft was unrecoverable and pulled hard on his eject handles. An explosive charge propelled him from the cockpit into the atmosphere with sufficient force to rip his left glove from his hand, scattering his canopy, pilot seat, and other plane-related debris into the sky. Bill Rankin had spent a fair amount of time skydiving in his career—both premeditated and otherwise—but this particular dive would be unlike any that he or any living person had experienced before.

Or since.

Alan Boyle describes the details behind NASA’s decision to go with simpler contracting for future commercial rocket contracts

Alan Boyle describes the details behind NASA’s decision to go with simpler contracting for future commercial rocket contracts.

If you read the article, you’ll notice that the opposition to this decision comes from a Congressman and the GAO. In both cases they cite safety as an issue, as is by some magic giving NASA a lot of bureaucratic approval rights on every design is going to make the rockets or capsules safer. All this will really do is slow things down, increase costs, and possibly increase risks as the companies will no longer have as many resources to focus on design issues. Instead, they will have to spend a fortune pleasing NASA bureaucrats.

And yes, I call them bureaucrats. Any NASA engineer who spends his or her time looking over the shoulder of another engineer — who is doing the real design work — is nothing more than a bureaucrat. Better to quit NASA and get a job with one of these new companies where you can do some real work.

A big sideways slip on Mars

3:15 pm

Mars Reconnaissance Orbiter today released an image of a really spectacular transform fault on Mars, a spot where the ground cracked and two sections moved sideways to each other. In this case, the sideways movement was about 300 feet. The image is posted below the fold.

Compare that with the Japanese magnitude 9 earthquake on March 11, which only shifted the seabed sideways 165 feet while raising it 33 feet. The quake that moved these two pieces of Martian bedrock sideways must have been quite a ride.

Rutan, Allen, Musk, Griffin team up to develop an air-launch rocket system to fire hardware and humans into orbit.

12:30 pm

Superstars of space: Rutan, Allen, Musk, and Griffin have teamed up to develop an air-launch rocket system to fire hardware and humans into orbit.

Their concept calls for Rutan, a noted aircraft designer, to create a carrier jet with a 385-foot wingspan and six engines to ferry a liquid-fueled, 120-foot-long rocket built by SpaceX and outfitted with five main engines to altitude where the winged booster will be released for launch into orbit.

Southwest orders 208 Boeing 737s valued at $19 billion

9:49 am

Some good news: Southwest Airlines has ordered 208 of Boeing’s 737, a deal valued at $19 billion. Plus this:

Last month, Boeing said Indonesia’s Lion Air committed to pay $21.7 billion for 230 Boeing 737s. Lion Air also has options for 150 more planes, valued at $14 billion, bringing the deal’s total potential value to $35 billion. But the Lion Air deal is not a certainty; it still has to complete the order. Also in November, Emirates Airlines ordered $18 billion worth of 777s.

Maybe Boeing should pump some of those profits into building the CST-100 manned space capsule and thus win more profits in the space tourism industry.

Orbital Sciences has renamed its Taurus II rocket the Antares rocket

2:49 pm

Orbital Sciences has renamed its Taurus II rocket the Antares rocket.

To clear up any marketplace confusion and provide clear differentiation between this new launch vehicle and our Taurus XL rocket. Antares is significantly different – it serves the medium-class space launch market and its liquid fuel first stage technology is major departure from previous Orbital space launch vehicles. In addition, a project of this scale and significance deserves its own name like Orbital’s Pegasus®, Taurus® and Minotaur rocket programs that have come before it.

I think they have also realized they needed to distinguish Antares from the Taurus XL rocket’s recent problems, failing twice to put NASA climate satellites into orbit.

An audit by NASA’s inspector general finds that NASA can’t keep track of its moon rocks

3:47 pm

An audit by NASA’s inspector general has found that NASA can’t keep track of its moon rocks.

In a report issued by the agency’s Inspector General on Thursday, NASA concedes that more than 500 pieces of moon rocks, meteorites, comet chunks and other space material were stolen or have been missing since 1970. That includes 218 moon samples that were stolen and later returned and about two dozen moon rocks and chunks of lunar soil that were reported lost last year.

Over-the-counter osteoporosis drug appears to keep astronauts from losing bone density on long space flights

10:14 am

Big news: New research on ISS now shows that the standard over-the-counter osteoporosis drugs used by millions on Earth appears to keep astronauts from losing bone density during long space flights.

Beginning in 2009, the group administered the drug to five long-stay astronauts on the International Space Station (ISS), including Koichi Wakata, 48, and Soichi Noguchi, 46. The five took the drug — an over-the-counter bisphosphonate used to treat osteoporosis — once a week starting three weeks before they lifted off until they returned to Earth. The researchers then monitored the astronauts’ bone mass over time and compared the results to those for 14 astronauts that had never taken the drug.

The results showed that the 14 who had never taken the drug had average bone density loss of 7 percent in the femur, and 5 percent in the hip bone. The five astronauts on bisphosphonate, however, only had average bone density loss in the femur of 1 percent, and even a 3 percent increase in the hip bone. Calcium levels in their urine, which rise the more bone mass is lost, were also very low.

If these results hold up, they might very well solve one of the biggest challenges faced by any interplanetary traveler. Up until now, bone loss during long weightless missions never seemed to average less than 0.5 percent per month. After spending three years going to and from Mars, an astronaut could thus lose about almost 20 percent of their bone mass in their weight-bearing bones, and would probably be unable to return to Earth.

Thus, a mission to Mars seemed impossible, unless we could build a ship with some form of artificial gravity, an engineering challenge we don’t yet have the capability to achieve.

If these already tested drugs can eliminate this problem, then the solar system is finally open to us all. All that has to happen now is to do some one to two year manned missions on ISS to test the drugs effectiveness for these long periods of weightlessness.
