SpaceX offers 10% discount for satellites launched on reused 1st stages

10:46 pm

In interview today for Space News, SpaceX’s president Gwynne Shotwell revealed that the company is only offering a 10% launch discount for any satellite launch that uses a reused Falcon 9 first stage, not the 30% price break she had indicated in March.

Though the interview also touched upon SpaceX’s September 1 launchpad investigation, it did not include anything significantly new. Shotwell readily admitted that the company did consider sabotage as a possible cause, but always considered it unlikely and right now has pretty much dismissed it. She also remains confident that the company will resume launches this year.

Stratolaunch to use Orbital ATK’s Pegasus rocket

10:32 pm

The competition heats up? Vulcan Aerospace and Orbital ATK announced today that they are renewing their partnership, using Pegasus in conjunction with Stratolaunch to put satellites into orbit.

Under a multiyear “production-based partnership,” the companies said, Orbital ATK will provide “multiple” Pegasus XL air-launch rockets to be used with the Stratolaunch aircraft, which, when completed, will have the largest wingspan of any plane ever built.

With the Pegasus XL rockets, the Stratolaunch aircraft will be able to launch small satellites weighing up to 1,000 pounds, according to the firms’ joint statement released Thursday. Pegasus rockets already have done this kind of work: Orbital ATK has used them to launch satellites from the belly of its Stargazer aircraft.

This deal suggests to me that Vulcan Aerospace has a problem. It couldn’t find anyone to build a large rocket for Stratolaunch and this deal was therefore conjured up to paper over this problem. First , it appears that the reason Orbital ATK originally backed out was that they didn’t want to build the new rocket. Maybe they had engineering concerns. Maybe they were worried about cost or management. Regardless, they didn’t want to build it.

Second, using Stratolaunch with Pegasus seems pointless if the satellite weigh is still limited to only 1,000 pounds. That’s the payload capacity of Pegasus using Orbital ATK’s L-1011 Stargazer airplane. Why bother switching to Stratolaunch if the giant plane doesn’t give you any benefits?

Thus, it appears to me that what has happened is that Vulcan needed some rocket to use with Stratolaunch so that they could squelch the rising doubts about the company. This deal gives them that. It also probably gives Orbital ATK some extra cash to get them to agree to do it.

Success for New Shepard launch abort test

3:56 pm

The competition heats up: Blue Origin’s New Shepard capsule not only successfully rocketed away from its propulsion module and landed safely, the propulsion module unexpectedly survived today’ launch abort test and landed vertically as well.

This was the fifth flight of the propulsion module, which with the capsule will now be retired and placed on display.

Below the fold is the video of the entire test flight, including countdown and several long holds. The actual launch is at 1:06:19.

Redesigned Antares launch scheduled for Oct 13

6:45 pm

NASA and Orbital ATK have now set October 13 as the date for the first Antares launch in two years.

Though ISS is not short of supplies, this quote underlines the difficulty of the particular situation now.

While the space station has plenty of food, water, experiments and other provisions, NASA officials are eager for the Antares rocket to resume flights as all of the research outpost’s other servicing vehicles are facing delays.

SpaceX’s Falcon 9 rocket, which launches the company’s Dragon cargo craft, is grounded after a launch pad explosion Sept. 1, and Dragon resupply missions to the space station may not start up again until early next year.

The Japanese HTV cargo freighter was supposed to blast off Sept. 30 with several tons of supplies, including new lithium-ion batteries for the space station’s electrical system. But that launch has been delayed until at least December after Japanese engineers discovered a leak during an air tightness test in August.

And a Soyuz crew capsule that was supposed to launch Sept. 23 with three new space station residents will not lift off until at least Oct. 19 after Russian workers discovered a technical problem on the vehicle. The Soyuz delay will likely push back the launch of Russia’s next unpiloted Progress cargo freighter from Oct. 20 until late November or early December.

Even with numerous redundent methods for hauling cargo to ISS, it is still possible for them all to have problems all at once.

Space letter wars in Congress!

6:34 pm

Turf war! A bi-partisan group of Congressmen, in response to an earlier letter by ten Republican senators questioning SpaceX’s ability to complete a thorough investigation of its September 1st launchpad explosion, have issued their own letter of support for the company.

In a letter to the heads of the Air Force, NASA and the Federal Aviation Administration, 24 members of Congress said that it was proper that SpaceX was leading the investigation. “Accidents are unfortunate events, and accident investigations should not be politicized,” wrote the bipartisan group led by Rep. Bill Flores (R-Tex.). “We encourage you to reject calls for your organizations to abandon established, well-considered and long-standing procedures.”

Ain’t democracy wonderful? It seems that SpaceX might have rounded up its own crony Congressmen to battle ULA’s crony Congressmen.

Agriculture Secretary demands Americans reduce their food portions

2:54 pm

We’re here to help you! The Obama administraton’s agriculture secretary on Monday called for Americans to stop wasting food by reducing their food portions.

Vilsack declared that “first and foremost, America can stop wasting food.”

“We can reduce portion sizes, we can have a more informed consuming public,” he said. “The USDA is providing an app that allows you to sort of go online and figure out if something’s been in the refrigerator for a couple of days, is it still OK to eat that type of thing? And if we can’t reduce it or reuse it, then we need to recycle it. So that’s one strategy that we’re working on.”

He was trying to outline ways to solve future food shortage issues as well as landfill shortages. However, this is really a case of the pot calling the kettle black. For example, I wonder if he has ever looked at the food that is routinely wasted at every Washington function at the fancy buffet tables that are made available to every participant. I doubt it. I suspect that food alone could probably feed the populations of several third world nations.

Morever, what business is it of his to tell us how much food we are allowed to eat? Since when did the federal government gain this power? Worse, I expect that every proposal that the government will try to solve the problem is only going to make it worse. Instead, the government should just shut up, get out of the way, and allow competition, freedom, and necessity to find solutions, quickly and in the most efficient manner.

Not sabotage!

6:55 am

This closer look at the circumstances behind the September 1 Falcon 9 launchpad explosion outlines why sabotage by a sniper is almost certainly not the cause of the explosion.

The rocket was destroyed about eight minutes before it could start its engines for the static test fire. The supposed sniper could have waited until first-stage engine ignition, which would have covered the sound of a shot. Even a suppressed rifle can be quite loud, and the passage of the bullet through the air would have generated a distinctive sound. As Elon Musk wrote on Twitter a while ago, his team did not come to that conclusion. “Particularly trying to understand the quieter bang sound a few seconds before the fireball goes off,” Musk tweeted. “May come from rocket or something else.”

The .50-caliber Barrett rifle has a maximum effective range of little over a mile. It would be extraordinarily difficult (albeit not impossible) for a trained sniper to get within rifle range of the launch pad, given the tight security at Cape Canaveral Air Force Station.

The article also notes that fuel tanks simply don’lt explode when you fire a bullet into them. Moreover, the problem came from the rocket’s second stage helium tank, and it would have been easier for a sniper to fire at the rocket’s first stage.

It was necessary for the investigation to look into this possibility, but it is also necessary to put the suspicion aside when it is found to be invalid. SpaceX had a rocket failure of significant importance on September 1st, and they need to uncover its actual cause in order to prevent it from happening again. Getting distracted by theories that don’t work will prevent them from doing that.

Firefly shuts down

6:39 am

More details have been released by the shut down of operations at Firefly Space Systems.

They have furloughed all their employees, having lost one of their major investors. According to the company, the investor did not pull out because of the company’s litigation with Virgin Galactic, but because of its own internal considerations. The article also includes hints that Firefly might be one of the options that Vulcan Aerospace is looking at for building the rocket that its giant airplane Stratolaunch will launch.

A detailed look at SpaceX’s Raptor engine

8:40 am

Link here. This story confirms for me a thought I had had while I watched Elon Musk’s talk last week outlining his proposed Interplanetary Transport System: SpaceX is still a good long way from actually building this rocket, since they have barely begun developing the rocket engine. They have made excellent progress in engine development, but they have a lot to do, with many pitfalls certain.

I therefore think that the company will be relying on its Falcon 9 and Falcon Heavy rockets, with their Merlin engines, for many more years to come.

Sabotage?

9:08 am

The competition really heats up: The SpaceX investigation into the September 1 Falcon 9 launchpad explosion has apparently also included looking into the possibility that sabotage could have played a part.

As part of the investigation, SpaceX officials had come across something suspicious they wanted to check out, according to three industry officials with knowledge of the episode. SpaceX had still images from video that appeared to show an odd shadow, then a white spot on the roof of a nearby building belonging to ULA, a joint venture between Lockheed Martin and Boeing. The SpaceX representative explained to the ULA officials on site that it was trying to run down all possible leads in what was a cordial, not accusatory, encounter, according to the industry sources, who spoke on the condition of anonymity because of the ongoing investigation.

The building, which had been used to refurbish rocket motors known as the SMARF, is just more than a mile away from the launchpad and has a clear line of sight to it. A representative from ULA ultimately denied the SpaceX employee access to the roof and instead called Air Force investigators, who inspected the roof and didn’t find anything connecting it to the rocket explosion, the officials said.

To quote Sherlock Holmes, “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.” In this case, it appears that they have eliminated this impossibility, though it is interesting that SpaceX felt compelled to consider it.
