Video of Saturday’s New Shepard flight

7:36 pm

Blue Origin has released video of its New Shepard test flight on Saturday, once again in a slick edited presentation rather than raw video of the flight itself. I have embedded this video below the fold.

As promised, the propulsion module came down at full speed until only a few seconds before impact, then fired its engines and gently slowed, then hovered, then touched down without harm. The long shot of it coming down is especially breathtaking.

New Shepard flies again, for the third time

1:23 pm

The competition heats up: On Saturday Blue Origin successfully launched and landed its reusable New Shepard suborbital capsule/rocket spacecraft

The vehicle lifted off from the company’s test site shortly after 11 a.m. Eastern time, according to a series of tweets by company founder Jeff Bezos. The vehicle’s propulsion module, the same one that flew earlier test flights in November and January, made a successful powered landing, he said. Its crew capsule, flying without people on board, parachuted to a safe landing. … The vehicle reached a peak altitude of nearly 103.4 kilometers, slightly above the “von Karman line” frequently used as the boundary of space and similar to previous test flights.

This flight also carried some science experiments, demonstrating that Blue Origin’s customers will not be limited merely to space tourists.

New Shepard to fly this weekend

4:39 pm

The competition heats up: Jeff Bezos indicated today on Twitter that the next New Shepard flight will be this weekend.

“Working to fly again tomorrow,” Blue Origin founder and Amazon.com CEO Jeff Bezos tweeted on Friday. “Same vehicle. Third time.” Adding to the intrigue, Bezos said there was a higher chance of a crash on the upcoming unmanned test flight. During its descent, the booster’s hydrogen-fueled BE-3 engine will re-light closer to the ground — just 3,600 feet up — and at higher thrust than before.

“Pushing the envelope,” said Bezos. “Impact in 6 sec if engine doesn’t restart & ramp fast.”

I will be out caving this weekend, so my reactions will have to wait until I return on Sunday night. Should be quite exciting however, especially as this will be third flight into space for this ship/rocket, a first as far as I know in space travel. There have been some vehicles reused, but I don’t remember any that reached space and were reused more than once.

Sierra Nevada favors Alabama for Dream Chaser’s commercial port

9:50 am

The competition heats up: At a workshop in Alabama this week Sierra Nevada’s vice president indicated that though the company has not yet finalized its decision, it is strongly leaning to picking Huntsville as the commercial spaceport for its Dream Chaser mini-shuttle, being built to ferry cargo to ISS.

“There was a leap of faith on the Huntsville side that we would be a company that could get this vehicle built and start servicing the space station…,” Sierra Nevada Vice President John Roth said Thursday. “Yes, we have been approached by other airports for ventures. We’re not moving forward at this time with any of those. Right now, Huntsville is the only community we’re moving forward with a (landing) license on.”

A preliminary local study identified four hurdles to landing Dream Chaser at the Huntsville International Airport: required licenses for the craft and airport, environmental impact approval, Federal Aviation Administration approval of the landing path and possible runway damage.

Why do I sense the unseen hand of porkmeister Senator Richard Shelby (R-Alabama) in this story? Could it be that one of the reasons NASA finally included Dream Chaser in its cargo contract was that the company had not only chosen the Alabama-based Atlas 5 rocket for its launch vehicle but was also courting Alabama for its commercial base, and Shelby had made it clear behind the scenes that he wanted that business? Could it be that Sierra Nevada is now returning the favor, having gotten the contract?

Don’t get me wrong. I think it was a good choice for NASA to give that contract to Sierra Nevada. I just think it important to note how giving some of our power away to politicians allows them to wield that power over us, sometimes to our benefit, sometimes against it, but always to make themselves more powerful. In the end, giving that power away is never a good option.

Opportunity takes a spin

9:36 am

In attempting several times this past week to climb the steepest ever tried by a rover on Mars and failing, Opportunity has moved on to a new less challenging target.

The rover’s tilt hit 32 degrees on March 10 while Opportunity was making its closest approach to an intended target near the crest of “Knudsen Ridge.”

Engineers anticipated that Opportunity’s six aluminum wheels would slip quite a bit during the uphill push, so they commanded many more wheel rotations than would usually be needed to travel the intended distance. Results from the drive were received in the next relayed radio report from the rover: The wheels did turn enough to have carried the rover about 66 feet (20 meters) if there had been no slippage, but slippage was so great the vehicle progressed only about 3.5 inches (9 centimeters). This was the third attempt to reach the target and came up a few inches short.

The rover team reached a tough decision to skip that target and move on.

Having operated thirteen years longer than originally planned, the science and engineering team that operates the Mars rover Opportunity are increasingly willing to try more risky things. For example, the valley the rover is in, called Marathon Valley, is actually an east-west slice through the rim of 14-mile-wide Endeavour Crater. Traveling into that slice towards the crater’s interior is a far riskier trip than ever dreamed of by Opportunity’s designs more than a decade ago.

Looking back at Comet 67P/C-G

9:27 am

Comet 67P/C-G backlit

Cool image time! As part of its research plan, Rosetta has been moved outward from Comet 67P/C-G for the next few weeks in order to better study its coma and tail. In this new position, engineers were able to maneuver the spacecraft so that it was flying about 600 miles farther from the Sun and could look back and see the Sun being eclipsed by the comet.

Thanks to the combination of a long, four-second exposure, no attenuation filter and a low-gain setting on the analogue signal processor of NAVCAM (a setting that is used to image bright targets), the image reveals the bright environment of the comet, displaying beautiful outflows of activity streaming away from the nucleus in various directions. It is interesting to note hints of the shadow cast by the nucleus on the coma below it, as well as a number of background stars sprinkled across the image.

In the next week the spacecraft will move back in close to the comet.

Ordered to reduce red tape, federal bureaucrats increased it

6:53 pm

Government in action: In response to two executive orders by President Obama ordering federal agencies to review their regulations to eliminate red tape and streamline government operations, federal bureaucrats added 6.5 million paperwork hours to their workload and increased regulatory costs by $16 billion even as they wrote these reviews.

The American Action Forum has found the reviews consist mostly of recycled regulations by federal agencies that have actually increased regulatory costs. “The recent ‘retrospective reports’ from the administration reveal that executive agencies have added more than $16 billion in regulatory costs, up from $14.7 billion in the previous update, and 6.5 million paperwork hours,” the report said.

The agency reviews are a result of President Barack Obama’s initiative for a “government-wide review of rules on the books,” which the White House claims to have led to $28 billion in net five-year savings since 2011. However, the American Action Forum has found retrospective reviews often add additional costs to the economy. A review in 2014 added $23 billion in costs and 8.9 million paperwork burden hours.

No one should be surprised by this. Asking agencies to review their regulations will instead be seen by them as a glorious opportunity to justify their existence with more work. The way to eliminate these regulations is for the elected officials in charge to, surprise!, eliminate these regulations. Don’t ask the bureaucrats to do it. Tell them to do it.

And when these bureaucrats go to the press to complain and say how the elimination of this or that regulation will cause the sky to fall, the politicians have to have the courage to not back down, even when the press teams up with the bureaucrats to slander them for trying to bring the federal government under control.
