The Falcon has landed

SpaceX has produced a short video that recaps its last launch and the successful landing of its first stage. I have embedded it below, because it is worth seeing again as the company is preparing to do it again this weekend. It is also worth watching again to see the joyous celebration of everyone watching at the moment, all of whom know deep down that they have just witnessed a significant event in the history of the human race.

SLS still has no mission

At a meeting at the Kennedy Space Center on Monday, outlining the status of the Orion/SLS program, managers admitted that the program still lacks funding for any missions past its initial 2018 unmanned test flight.

Internally, a huge amount of work is continuing to take place on providing SLS with Design Reference Missions (DRMs). However, those are only for planning purposes and the outlook continues to change, resulting in uncertainty. Numerous factors are to blame, with funding once again mentioned as an issue during the KSC meeting – citing SLS is “lacking booked missions at this time due to tight funding.”

In other words, Congress has not provided NASA any funding for any real SLS missions. I also don’t expect Congress to ever do so, since the cost per launch ranges from $3 to $14 billion, depending on how you calculate the numbers. This is in comparison to the estimated per launch cost of about $100 to $150 million for a Falcon Heavy launch, capable of putting in orbit about two-thirds that of SLS. Even a stupid Congressmen can read these numbers and figure out that they will get a lot more bang per buck dumping SLS for Falcon Heavy.

Daft Punk – Get Lucky

An evening pause: Hat tip Kyle Kooy. I don’t think the Chinese military realized that they were marching to this music, but gosh darn it, they sure appear to. As Kyle noted to me, “Somebody took a Chinese military parade and set the music to the American song “Get Lucky” by Daft Punk. … [It] creates a very mesmerizing video that is both upbeat and somewhat eerie at the same time.”

Gaming Obamacare

Finding out what’s in it: The Obama administration and health insurers are discovering that, because of the high cost of health insurance forced on consumers due to Obamacare, those consumers are improvising ways to “game the system”.

The article describes a whole range of tricks citizens are discovering that allow them to get insurance companies to pay for their health costs while paying those same insurance companies as little as possible. This example, which is not the focus of the story, encapsulates for me the entire insane nature of this monstrous law, forced upon us by Obama and the Democratic Party:

[Insurance companies] note many people have figured out they need pay for only nine months to get a full year of coverage. An enrollee might buy an ACA policy, get their health needs addressed and then let their coverage lapse — without having to pay the penalty for being uninsured.

It is only going to get worse. By not letting the free market function, the government is forced to ration care and impose restrictive rules, which people naturally try to improvise their way around, either legally or in a black market. The solution proposed in the article is even more restrictive rules and rationing.

The only real solution is to dump the whole thing and go back to the basic American principle of a free market. Such a system carries risk, but it forces the industry and the citizenry to find the most efficient solutions. It also depends on a very radical concept: personal responsibility.

Former Virgin Galactic employee battles company in court

A former employee of Virgin Galactic, in a arbitration dispute, has accused the company of lying about its spacecraft’s safety and performance.

Virgin Galactic’s former vice president of propulsion, Thomas Markusic, has accused Richard Branson’s space company of lying about the safety and performance of its SpaceShipTwo suborbital tourism vehicle. “Dr. Markusic was forced to separate from VG [Virgin Galactic] because the company was defrauding the public about the ability of the vehicles to reach space and was utilizing rocket engine technologies that have a high probability of causing catastrophic failure and loss of life,” according to the document. “VG directed Dr. Markusic to lie to customers about the performance and safety of the company’s hybrid rocket technology,” the document continues. “VG asserts that Dr. Markusic secretly plotted to start his own rocket company and exploited his position at VG; whereas, in reality, Dr. Markusic’s conscience forced him to to leave.”

Read the whole thing. It appears Markusic left Virgin Galactic to form his own company, and in doing so might have violated an anti-competition clause in his contract, resulting in the arbitration dispute. At the same time, his accusations ring true, considering these rumors had been flying about at the time and have since been more or less confirmed.

Crater close-ups from Dawn

Kupalo Crater on Ceres

The Dawn science team today released a set of close-up images of several craters on Ceres, showing a number of geological features similar but different than features seen in lunar craters.

The image on the right, of Kupalo Crater, shows the same kind of bright material on the rim that is seen on the floor of Occator Crater as two bright areas. The bright material is now believed to be a salt deposit leeched from beneath the surface. Other craters showed extensive fractures in their floor as well as lobes and scarps.

Was the Wow! signal from two comets?

One of the most baffling radio astronomical detections, dubbed the “Wow! signal” and that some believe could have been caused by an extraterrestrial transmission, is now theorized to have been caused by two comets, not an alien civilization.

Antonio Paris, a professor of astronomy at St Petersburg College in Florida, thinks the signal might have come from one or more passing comets. He points the finger at two suspects, called 266P/Christensen and P/2008 Y2 (Gibbs). “I came across the idea when I was in my car driving and wondered if a planetary body, moving fast enough, could be the source,” he says.

Comets release a lot of hydrogen as they swing around the sun. This happens because ultraviolet light breaks up their frozen water, creating a cloud of the gas extending millions of kilometres out from the comet itself. If the comets were passing in front of the Big Ear in 1977, they would have generated an apparently short-lived signal, as the telescope (now dismantled) had a fixed field of view. Searching that same area – as subsequent radio telescopes did – wouldn’t show anything. Tracing the comets’ positions back in time, Paris says that the possible origin for the Wow! signal falls right between where they would have been.

Neither comet was known in 1977; they were both discovered in the last decade, which would mean nobody would have thought to search for them.

Philae officially dead

After another attempt to contact Rosetta’s lander Philae ended with no response, engineers now consider the spacecraft dead

“We did not hear anything,” says lander manager Stephan Ulamec. In the best-case scenario, Philae may have received the command and moved, but be unable to respond due to a damaged transmitter. It is more likely that the signal was not received. The team will try a few more commands, but it looks like Philae has officially gone. “We have to face reality, and chances get less and less every day as we are getting farther and farther away from the sun,” says Ulamec. “At some point we have to accept we will not get signals from Philae anymore.”

Mighty Saturn

Saturn

Cool image time! Be sure to click on this link to see the full resolution Cassini version of the image on the right. Its resolution is 10 miles per pixel, and even so the giant planet cannot be fit in the frame.

One moon, Tethys, is visible, though to make it so required its brightness to be increased by 2. Also, if you look close at the bands at the north pole you can see their strange still-not-understood pentagon shape.
