Want to watch a nuclear bomb go off? You can!

Engineers at Lawrence Livermore National Laboratory (LLNL) have obtained declassified films of many of the nuclear tests performed by the U.S. from 1945 to 1962 and are digitally scanning them and preserving them for posterity.

Conducted by LLNL weapon physicist Greg Spriggs and a team of film experts, archivists, and software developers, the project’s goal was to track down as many as possible of the ten-thousand 2,400 frames per second reels of film. This was because the cine film, and its immense historical and scientific value, was in danger of being lost for all time. The reels were mostly of acetate stock that was not stored under anything like ideal conditions and was slowly decaying or being attacked by fungus and microbes.

“You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films,” says Spriggs. “We know that these films are on the brink of decomposing to the point where they’ll become useless. The data that we’re collecting now must be preserved in a digital form because no matter how well you treat the films, no matter how well you preserve or store them, they will decompose. They’re made out of organic material, and organic material decomposes. So this is it. We got to this project just in time to save the data.”

You can view a number of the films at the second link above. I have embedded below the fold just one, from Operation Teapot in 1955. This was a series of 14 tests in Nevada. In this particular video the explosion occurs in the air, and you can sense the incredible force of the explosion when the shock wave hits the ground and bounces back, producing the mushroom cloud. Not much would have survived that impact.

SpaceX successfully launches commercial satellite

The competition heats up: SpaceX tonight successfully launched Echostar 23.

This launch is almost four weeks after their last launch, which sent a Dragon capsule to ISS. Their goal this year has been to do one launch every two weeks, a goal they have not yet reached. The next launch, which will also place a commercial communications satellite into orbit, is tentatively set for March 27, and will also be the first launch that reuses a first stage. If they make that happen it will be first time they have hit the two week launch rate this year. They will then try to follow with another Dragon resupply mission, this time reusing a Dragon capsule for the first time.

House leans to less regulation of commercial space

During a hearing on March 8 of the House subcommittee on space the representatives overall pushed for less regulation of commercial space activities.

The overall problem was once again dealing with the Outer Space Treaty:

At a March 8 hearing of the subcommittee, members and witnesses grappled with the issue of how the government should oversee emerging commercial space activities in order to comply with obligations to the Outer Space Treaty, including whether such oversight is, in fact, required. Such “authorization and continuing supervision,” as specified in Article 6 of the treaty, is handled today by various agencies for commercial communications and remote sensing satellites and for launch. It’s less clear who would regulate new activities, ranging from commercial lunar landers to satellite servicing efforts, creating uncertainty in industry about who, if anyone, could provide that authorization and continuing supervision.

An April 2016 report delivered to Congress by the White House’s Office of Science and Technology Policy, required by Section 108 of the Commercial Space Launch Competitiveness Act of 2015, recommended what it called a “mission authorization” approach for providing that oversight. This approach would be modeled on the payload reviews performed by the Federal Aviation Administration during the launch licensing process, including an interagency review of proposed missions. While the mission authorization concept had won support from many in industry, as well as the FAA and some members of Congress, a change of administrations and its approach to regulation has emboldened some who want to limit industry regulation.

“Unfortunately, the Obama administration issued a report last year that called for expansive regulations over all types of private space activities,” said Rep. Lamar Smith (R-Texas), chairman of the House Science Committee, at the hearing. He cited a “crisis of overregulation” in general as a reason to oppose the previous administration’s proposal.

The House members and the witnesses apparently rejected the regulatory proposals that had been put forth by the Obama administration, and were instead searching for ways to limit the amount of regulation required under the Outer Space Treaty.

I say, dump the treaty. Nothing in it helps the development of space by private individuals or companies. Everything in it encourages bureaucracy and the limitation of private property.

SpaceX wins another Air Force launch contract

The competition heats up: SpaceX has been awarded a $96.5 million contract to launch an Air Force GPS satellite.

This price is about $14 million more than the last SpaceX Air Force launch contract. That’s probably because SpaceX was trying to undercut ULA’s price by as little as possible so that they could increase their profit. Until there are others in the business who can compete with SpaceX’s prices, the company is sitting pretty in any competitive bidding situation. Their costs are less, so they can always beat everyone else’s prices, while maximizing their profits.

Microsoft inserts ads in Windows 10

Why I use Linux, part 5,234,657: Microsoft is now inserting advertisements for its software throughout its Windows 10 operating system.

Microsoft has taken the next step in pushing advertising on customers of its Windows 10 operating system, with users reporting an advertisement for Microsoft OneDrive now appearing in their File Explorer.

Windows 10 has been repeatedly reprimanded by technology journalists over the past year for the increasing amounts of advertising that are baked into the system. Advertisements in various forms have appeared in the Start menu, the lock screen, the taskbar, in the Windows Store, and various other areas. This seems to be the first time that users are noticing them in the File Explorer, the application that allows users to look through their documents and applications on their computer.

As I have been saying for years, dump Windows. It invades your privacy, provides you bad service while crashing at the worst possible moments. There are alternatives. I have been using Linux now for more than a decade, and it hasn’t held me back. Here again are the links to James Stephens’ series on Behind the Black for Getting and Installing Linux:

Parachute tests for Boeing Starliner

Boeing’s Starliner spacecraft has successfully completed a parachute test at New Mexico’s Spaceport America.

Uniquely, this test wasn’t conducted via the use of a helicopter of an aircraft – as seen with other vehicles, such as the Orion spacecraft. Boeing was not able to fit the Starliner test article into the hold of a C-130 or C-17 aircraft, so they instead used a 1.3-million-cubic-foot balloon, which is able to lift the capsule to its intended altitude.

The test went well, with Starliner released from the balloon, deploying two drogue parachutes at 28,000 feet to stabilize the spacecraft, then its pilot parachutes at 12,000 feet. The main parachutes followed at 8,000 feet above the ground prior to the jettison of the spacecraft’s base heat shield at 4,500 feet. Finally, the spacecraft successfully touched down.

The article once again makes note of NASA’s fake concern over the Atlas 5 rocket. The concern isn’t that the rocket isn’t reliable. The concern is that Boeing hasn’t yet gotten NASA’s certification that it is reliable. In other words, because NASA hasn’t signed a piece of paper stating the obvious fact that the Atlas 5 is safe, Boeing’s Starliner cannot be considered safe.

Congress micromanages rocket development at ULA

Corrupt Congress: Even though ULA favors Blue Origin’s BE-4 engine for its Vulcan rocket, various elected officials in Alabama are pushing the company to use Aeroject Rocketdyne’s AR-4 engine instead.

At the end of February, two US representatives, Mike Rogers of Alabama [Republican] and Mac Thornberry of Texas [Republican], decided to push a little harder. On February 28, they sent a letter to Lisa Disbrow, the acting secretary of the US Air Force, and James MacStravic, who is performing the duties of the undersecretary of defense for acquisition, technology, and logistics. In addition to reiterating a desire that ULA continue to fly a second rocket, the Delta IV Heavy, the letter urges the Pentagon officials to be skeptical about the BE-4 engine.

“The United States Government (USG) must have a hands-on, decision-making role… in any decision made by United Launch Alliance to down-select engines on its proposed Vulcan space launch system, especially where one of the technologies is unproven at the required size and power,” the letter states. “If ULA plans on requesting hundreds of millions of dollars from the USG for development of its launch vehicle and associated infrastructure, then it is not only appropriate but required that the USG have a significant role in the decision-making concerning the vehicle.” The letter then goes on to say the Air Force should not give any additional funding to ULA, other than for current launch vehicles, until the company provides “full access, oversight of, and approval rights over decision-making” in its choice of contractors for the engines on Vulcan.

The article also mentions porkmaster Senator Richard Shelby (R-Alabama), who also favors Aerojet Rocketdyne because they say they will build it in Alabama. Note also that these elected officials are not only trying to pick the winner in the private competition between these two rocket engines, they also want to force ULA to keep using the Delta rocket, even though it is very expensive and not competitive with the newer rockets being developed by other companies. And their only reason for doing so is because they provide jobs for their districts.

This one story illustrates perfectly the corruption that permeates both parties in Congress. While it is more likely that Democrats will play this pork game, there are plenty of corrupt Republicans who play it as well. These petty dictators all think they have the right to interfere in the private efforts of Americans, whether it involves building a new rocket or buying health insurance. And all we get from this is a poorer nation and a bankrupt federal government.

Blue Origin signs second contract for New Glenn

The competition heats up: One day after announcing its first launch contract, Blue Origin announced today a second contract for its New Glenn rocket.

In a tweet this morning, Blue Origin Founder Jeff Bezos said OneWeb has reserved five launches using the rocket, bringing to six the number of missions in the New Glenn manifest.

So far I can find no information about the prices being charged by Blue Origin for these launches. I suspect they are giving their customers discounts for being the first, but this is not confirmed yet.
