ULA concedes GPS competition to SpaceX

8:47 am

The competition cools down: ULA has decided against bidding on a military GPS launch contract, leaving the field clear for SpaceX.

ULA, which for the past decade has launched nearly every U.S. national security satellite, said Nov. 16 it did not submit a bid to launch a GPS 3 satellite for the Air Force in 2018 in part because it does not expect to have an Atlas 5 rocket available for the mission. ULA has been pushing for relief from legislation Congress passed roughly a year ago requiring the Air Force to phase out its use of the Russian-made RD-180 engine that powers ULA’s workhorse Atlas 5 rocket.

This decision might be a lobbying effort by ULA to force Congress to give them additional waivers on using the Atlas 5 engine. Or it could be that they realize that they wouldn’t be able to match SpaceX’s price, and decided it was pointless wasting time and money putting together a bid. Either way, the decision suggests that ULA is definitely challenged in its competition with SpaceX, and until it gets a new lower cost rocket that is not dependent on Russian engines, its ability to compete in the launch market will be seriously hampered.

Copenhagen Phil – Ravel’s Bolero

6:01 pm

An evening pause: You really can’t pick a better classical piece for a flash mob performance than Bolero. It builds bit by bit, allowing the performers to slowly gather as if by accident. I also noticed that they seemed to be really enjoying the casual dress nature of this performance, which occurred at Coperhagen Central Station on May 2, 2011..

Hat tip Danae.

Vizio smart televisions watch YOU

10:12 am

If you are going to buy a smart television, don’t buy one by Vizio, as they by default track your viewing and provide the information to advertisers.

The feature, “Smart Interactivity,” is already turned on as a default setting for millions of people who have purchased the device. Viewers are able to turn off the setting, that is, if they know it even exists. “Non-personal identifiable information may be shared with select partners… to permit these companies to make, for example, better-informed decisions regarding content production, programming and advertising,” Vizio said in a statement.

Vizio seems to be taking a new approach by tracking viewers by default, while competitors like San Jose-based Samsung or LG Electronics leave it to customers to turn the setting on. Vizio’s sharing with advertisers also reportedly lets them target devices like your phone, which other companies do not.

Somehow this seems to be a direct violation of privacy, which also might be quite illegal.

Bibles banned from school libraries in Tennessee

9:19 am

Fascists: Because of a complaint, a Tennessee school administrator has banned Gideon Bibles from providing free bibles to the school’s libraries.

Superintendent Jennifer Terry would not elaborate on the complaints made. In a statement to Channel 3 News, she said the school system will no longer allow any religious group or material to be distributed. “Bledsoe County Schools do not allow the distribution of religious materials from any religious groups. The distribution of religious materials in a public school is in violation of constitutional provisions and well established federal and state laws and precedence,” Jennifer Terry, Director of Schools in Bledsoe County

This is insane. The government is not establishing a state religion by accepting free bibles from private American citizens for its libraries. It is a library, where books are made available to read. If the school can get some of those books free they should take them. To suggest that a government-run library can’t contain any religious books is the height of stupidity.

The article suggests that the community plans to protest this at the next school board meeting. It will be interesting to see what happens.

Dubai to use jetpacks to fight fires

8:59 am

Buck Rogers lives! In order to better fight fires among its many high skyscrapers, Dubai officials have purchased 20 jetpacks for use by its firefighters.

Martin Jetpacks have been developed with first responder use in mind. They can be flown by a pilot or via remote control, take off and land vertically, operate in confined spaces (such as close to or between buildings or near trees) and carry commercial payloads of up to 120 kg (265 lb). This functionality means the Jetpacks can provide a variety of first response services. For example, they can be used for surveillance or observation (such as to determine the focus of a fire), transporting equipment to where it is required, rescuing individuals or deploying specialist teams.

Though it sounds cool, remotely controlled drones would make more sense for most of these tasks. The jetpacks might be useful for getting crews in and out of difficult high locations, as well as possibly rescuing trapped victims, but to make this practical will require significant training, something that I don’t see as realistic.

SpaceX successfully tests its Dragon capsule abort rocket thrusters

10:39 am

The competition heats up: SpaceX has successfully tested its abort rocket thrusters that will be used to speed a Dragon capsule away from any rocket during a failed launch.

Named SuperDracos, the engines are arranged in four pairs – SpaceX calls them ‘jetpacks’ – integrated around the outside of the Crew Dragon spacecraft. Firing all at once, the eight engines produce 120,000 pounds of thrust – enough power to accelerate a Crew Dragon from zero to 100 mph in 1.2 seconds. In the unlikely event of an emergency, that power means the ability to lift the crew a safe distance off the launch pad or far away from a booster failing on the way to orbit. That capability was demonstrated earlier this year in a pad abort test that confirmed the SuperDraco design in a flight-like condition.

A normal launch of the Crew Dragon atop a Falcon 9 rocket would not offer the SuperDracos anything to do during the mission since their only responsibility is to fire in an emergency to rescue the crew onboard. Eventually, SpaceX plans to use the SuperDracos in the place of a parachute during landing.

Congress revises law governing commercial space

10:32 am

The competition heats up? Congress this week passed a revision to the Commercial Space Act that they claimed will help encourage the growth of the new industry.

According to the Senate press release, the bill does the following:

  • Extend the liability waiver for private space launches until 2023
  • Extend ISS operations until 2024
  • Establishes a legal right for U.S. companies to mine resources in space
  • Demands a new more streamlined framework for the government’s regulation of the industry

The last item is probably mostly blather, since a close look at the bill itself [pdf] reveals that most of these demands are merely requirements that the executive branch write a report. The odious rules that will allow the federal government to regulate and restrict the industry all remain. And even though the bill makes a big deal about establishing these regulations in concert with the industry itself, that only means that today’s players can use the government to make it difficult for new players to get started.

The claim that the bill also establishes “a legal right to resources a U.S. citizen may recover in space consistent with current law and international obligations of the United States,” as noted in the Senate press release, is a very big overstatement. The bill’s wording does nothing to get the U.S. out of the UN’s Outer Space Treaty, which forbids any person or nation from claiming ownership of territory in space. All the bill does is express the desire that American citizens should have the right to own what they mine, while at the same time stating that these resources will be “obtained in accordance with applicable law, including the international obligations of the United States.’’ In other words, the Outer Space Treaty still applies, and you can’t own it.

For what it’s worth, the bill also renames the FAA’s space regulatory agency from “The Office of Space Commercialization” to “The Office of Space Commerce.”

All in all, the bill’s most important overall accomplishment is that it strongly emphasizes and encourages the development of a private space industry, and tries to focus the government’s regulatory efforts in that direction. This ain’t perfect, but it could be considered a step in the right direction.

One more thing to note: Senator Ted Cruz (R-Texas) appears to have been a major player in getting this bill written and passed.

Another new American rocket engine tested successfully

9:58 am

The competition heats up: Sierra Nevada has successfully tested a new rocket engine, dubbed Vortex, specifically designed to fulfill a wide range of uses. From the press release:

These tests demonstrate the ability to transition use of different propellant combinations in the same core rocket engine design with slight changes to accommodate a specific combination of fuel and oxidizer, including propane and kerosene fuels with nitrous oxide (laughing gas) and liquid oxygen oxidizers. This latest development offers customers a suite of engines scalable to higher thrust levels and customer-selected fuel combinations from a single core rocket engine design. ORBITEC’s patented vortex rocket engines utilize a unique swirling propellant flow to naturally cool the engine walls, allowing for the development and manufacture of simpler, low-cost, light-weight and more robust rocket engine systems.

What strikes me about this is that, until SpaceX built its Merlin engine in the mid-2000s, it had been decades since the American aerospace industry had developed a new rocket engine. After the development of the shuttle’s main engines in the late 1970s nothing new was created for the rest of the 20th century. Since Merlin, however, we have seen a string of new engines from several different companies, suggesting that the new renaissance I wrote about back in 2005 is on-going and accelerating.

Why cold fusion and NASA’s EM Drive are most likely frauds

7:55 am

Link here. The writer does a nice job of explaining why impossible engines that appear to defy basic laws of physics are almost certainly incapable of doing what they promise, and are likely frauds.

An extraordinary result has to come with extraordinary evidence. When someone claims they have come up with something that can do something that engineers have been unable to do for centuries — since the very beginnings of the Industrial Age — I get very very suspicious, especially when their evidence is scanty and their data is not open for study.
