The Russian company that owns the Proton rocket is considering a redesign that would allow them to launch two satellites on one rocket.

8:36 am

The competition heats up: The Russian company that owns the Proton rocket is considering a redesign that would allow them to launch two satellites on one rocket.

Launching two or more satellites during a single launch is not ground-breaking technology, but the Russian have never done it with their Proton. If they make this change, it will allow them to reduce the cost for a commercial launch considerably, thus making them more competitive against companies like SpaceX.

That they have decided to consider this now, after almost three decades of commercial operation since the fall of the Soviet Union, is more proof that the low prices of SpaceX are forcing innovation and an effort to lower costs across the entire launch market.

Update: My statement above about Proton never launching more than one satellite is wrong. They have done it numerous times, something I am very aware of but for some reason completely forgot when I was writing this post. (The jet lag from the trip to Israel must still be affecting my brain.) In fact, they have just rolled to the launchpad a Proton with two communications satellites on board, a fact that makes the story at the first link above very puzzling.

The comet that the European probe Rosetta will visit in August has awakened.

11:37 am

The comet that the European probe Rosetta will visit in August has awakened.

Already 67P/Churyumov-Gerasimenko is approximately 50 percent brighter than in the last images from October 2013. While the comet has moved another 50 million kilometers closer to Earth in this time (and 80 million kilometers closer to the Sun), the increase in brightness cannot be explained by the smaller distance alone. “The new image suggests that 67P is beginning to emit gas and dust at a relatively large distance from the Sun”, says Colin Snodgrass from the MPS. This confirms a study presented by Snodgrass and his colleagues last year in which they had compared the comet’s brightness as recorded during its previous orbits around the Sun. The calculations showed that already in March 2014 its activity would be measurable from Earth.

Update: A preprint paper published today on the astro-ph website predicts that Rosetta will see an unusual topographical feature on the comet’s surface when it arrives in August:

Comet 67P/Churyumov-Gerasimenko. The Secular Light Curve (SLC) of this comet exhibits a photometric anomaly in magnitude that is present in 1982, 1996, 2002 and 2009. Thus it must be real. We interpret this anomaly as a topographic feature on the surface of the nucleus that may be a field of debris, a region made only of dust or an area of solid stones but in any case it is depleted in volatiles. We predict that images taken by spacecraft Rosseta will show a region morphologically different to the rest of the nucleus, at the pole pointing to the Sun near perihelion.

On Saturday SpaceX successfully conducted a dress rehearsal countdown and static fire engine test of the Falcon 9 rocket that will loft a Dragon capsule to ISS next week.

The results of the test itself have not been released, but that it was completed suggests all is well for the upcoming launch.

Neil deGrasse Tyson poo-poos private space.

8:39 am

Standing on the wrong side of history: Neil deGrasse Tyson poo-poos private space.

Tyson described space travel as “a long-term investment”: “It’s an investment that private enterprise cannot lead.” He recalled the excitement around SpaceX’s delivery of cargo the International Space Station, which sparked discussion about whether private companies would replace government as the main engine behind space travel. Tyson’s response? “They brought cargo to the space station! NASA’s been doing that for 30 years!”

Tyson, who also said that government is the only one willing to do exploration and that private space only comes after, will probably push this agenda on his new Cosmos television series.

On this subject, Tyson has the outdated opinions of today’s leftwing academic community. And he is wrong. The only reasons private space didn’t lead in the past fifty years is because our federal government was against it. It wanted the turf all to itself and the private companies who could have done it were willing to acquiesce. Now that this monopoly is crumbling, stand by to see private enterprise dominate the show.

Virgin Galactic is close to getting its FAA launch license.

5:19 am

According to the company’s CEO, Virgin Galactic is close to getting its FAA launch license.

The CEO also said that they hope to fly their first suborbital flight this summer after several lower altitude powered flights.

At this point I will believe this when I see it. Virgin Galactic has made promises like this repeatedly for the past three years, none of which have come true. The time has come for them to put up, or shut up, or finally tell us the truth.

In testimony to Congress Wednesday, Elon Musk described how allowing SpaceX to compete as a military launch provider would significantly lower costs.

7:49 am

The competition heats up: In testimony to Congress Wednesday, Elon Musk described how allowing SpaceX to compete as a military launch provider would significantly lower costs.

[Senator Richard Shelby (R-Alabama)] said the Air Force EELV contracts require compliance with complex oversight and accounting practices that add costs to the program. As a result, he suggested comparing the cost of a SpaceX Falcon 9 and a ULA Atlas or Delta was comparing apples and oranges.

Musk agreed “there is additional cost for U.S. government missions due to the mission assurance process.” And he said SpaceX’s costs for launching a military mission would be 50 percent higher than for a purely commercial launch. Even so, he said, SpaceX could provide a Falcon 9 rocket for around $90 million as opposed to nearly $400 million for a ULA launcher. “Even when you add the Air Force overhead, there’s still a huge difference,” he said. [emphasis mine]

The only reason that Congress is against eliminating the military launch monopoly given to ULA and allowing SpaceX to compete is because the monopoly feeds a lot of pork to the districts of certain but powerful legislators like Shelby.

ULA and Shelby are losing the argument however. The cost differences are too high, and SpaceX has proven that it can do the job efficiently and effectively. Eventually the monopoly will die, and the sooner the better.

China finally reveals Yutu’s problem: the failure of a control circuit prevents it from storing its solar panels during lunar night.

8:02 am

China finally reveals Yutu’s problem: the failure of a control circuit prevents it from storing its solar panels during lunar night.

A functioning control circuit is required to lower the rovers mast and protect the delicate components and instruments mounted on the mast from directly suffering from the extremely harsh cold of the Moon’s recurring night time periods. “Normal dormancy needs Yutu to fold its mast and solar panels,” said Ye. The high gain communications antenna and the imaging cameras are [also] attached to the mast. They must be folded down into a warmed electronics box to shield them from the damaging effects of the Moon’s nightfall when temperatures plunge dramatically to below minus 180 Celsius, or minus 292 degrees Fahrenheit.

“What happens if Russia refuses to fly U.S. astronauts?”

7:58 am

“What happens if Russia refuses to fly U.S. astronauts?”

The problem: the situation in the Ukraine. If tension between the U.S. and Russia worsens then Russia might suspend carrying American astronauts to and from ISS.

The fault here belongs with Congress and George Bush, who decided in the 2000s to let the shuttle retire before its replacement was ready. In addition we can blame Congress in the 2010s for forcing NASA to spend billions on the unaffordable Space Launch System rather than focus on getting humans into space cheaply and quickly.

A retired NASA manager is suing the Discovery Channel for its false portrayal of his action in connection with the Challenger shuttle accident.

7:49 am

Fake but accurate: A retired NASA manager is suing the Discovery Channel for its false portrayal of him in a movie about the Challenger shuttle accident.

The suit says that in the movie’s crucial scene Lovingood is shown testifying falsely that the odds of a shuttle failure were much higher than other NASA engineers calculated. … “The clear statement and depiction was that Lovingood lied about the probability of total failure being 1 in 100,000 when NASA’s own engineers said it was 1 in 200,” the lawsuit says. “This movie scene never took place in real life at any hearing. (Lovingood) was never asked to give any testimony as depicted and he did not give testimony to the question shown in the movie in this made up scene.”

“It makes it look like (NASA leadership) ignored a highly risky situation” in deciding to launch Challenger that day, Lovingood’s attorney Steven Heninger of Birmingham said Friday. Heninger said the movie was the network’s “first attempt at a scripted program … and they took shortcuts because they were writing for drama.” The testimony in the movie was not in the investigation commission’s records or Feynman’s book “What Do You Care What Other People Think?,” both of which were sources for the film, the suit claims.

Though NASA management did consistently claim the shuttle was safer than it actually was, to falsely portray this specific individual as the person who said those lies when he did not is without doubt slander. I hope he wins big.

This is, by the way, a nice example of typical media arrogance. If you are going to fictionalize real events for dramatic purposes, you don’t use the names of real people and put words in their mouth when you do so. It leaves you very vulnerable legally to exactly this kind of lawsuit. That the Discovery Channel did so is good evidence they think they are above the law and do not have to care if they destroy people’s lives.

An investigation into the dangerous leak of water into a spacesuit during a spacesuit last July has found that NASA engineers had missed an earlier failure of the same suit.

The leak had first happened in a spacewalk a week earlier, and engineers misdiagnosed the problem. In addition, it appears they didn’t look closely enough at it.

Meanwhile, the investigation has pinpointed the cause of the leak as a clogged filter, but still could not trace what caused that clog.

NASA is preparing the next round of commercial contracts to supply cargo to ISS.

1:34 pm

The competition heats up: NASA is preparing the next round of commercial contracts to supply cargo to ISS.

NASA announced the plan in a request for information released late Feb. 21. Responses from industry are due March 21. The document, which NASA posted online, did not say when the agency would solicit bids, or when it would make an award for the Commercial Resupply Services 2 (CRS) contract. The expected budget for CRS 2 is between $1 billion and $1.4 billion a year from 2017 to 2024, NASA said. NASA envisions four to five flights a year under CRS 2. Back in January, the White House announced it wanted to extend space station operations through 2024. Congress has currently committed to fund the space station through 2020. CRS 2 contract calls for delivery of 14,250 to 16,750 kilograms per year of pressurized cargo, and delivery of 1,500 to 4,000 kilograms per year of unpressurized cargo.

Assuming both SpaceX and Orbital Sciences win new contracts, this will give them a strong cash flow as they pursue new space endeavors.

The consolidation of the Russian aerospace industry continues as the government considers taking over privately owned Sea Launch.

11:42 pm

The consolidation of the Russian aerospace industry continues as the government considers taking over privately owned Sea Launch.

The Russian government will a take closer look at the idea of buying commercial launch services provider Sea Launch, which is owned by a top Russian space contractor but whose key assets are based in California, Russia’s Deputy Prime Minister Dmitry Rogozin said Feb. 19. Moscow has asked the Russian space agency, Roscosmos, and Russian manufacturer RSC Energia, which holds 95 percent of Swiss-registered Sea Launch, to submit an overview of the financial situation of the maritime launch services company, Rogozin said in remarks posted on the Russian Cabinet website. The Russian government holds 38 percent of Energia, which supplies the upper stage of the Sea Launch rocket.

Should the government go forward with the deal, it likely would move the oceangoing rocket pad and command ship from Long Beach, Calif., to a Russian port on the Pacific Ocean, Rogozin said. “Something tells me that if we go for it, then the base will definitely be outside the United States,” he said.

Without question the Putin government is trying to recreate the top-down centralized system that existed during the Soviet era, with everything controlled and even owned by the government. While this might please their love of power, I doubt it will be an effiicent way to compete in the open commercial market.

Which means this consolidation is a wonderful opportunity for the new private launch companies. Soon, Russia will be out of the market, focused instead on launching Russian only satellites and spacecraft.

A ruling by “a fatwa committee” in the United Arab Emirates now forbids Muslims from going on a one way mission to Mars.

8:17 am

A ruling by “a fatwa committee” in the United Arab Emirates now forbids Muslims from going on a one way mission to Mars.

“Such a one-way journey poses a real risk to life, and that can never be justified in Islam,” the committee said. “There is a possibility that an individual who travels to planet Mars may not be able to remain alive there, and is more vulnerable to death.” Whoever opts for this “hazardous trip”, the committee said, is likely to perish for no “righteous reason”, and thus will be liable to a “punishment similar to that of suicide in the Hereafter”.

Suicide and martyrdom in the name of Islam, however, is perfectly all right.

Russia on track to test launch its new Angara rocket before June.

8:10 am

The competition heats up: Russia on track to test launch its new Angara rocket before June.

A full-scale mockup of the rocket was rolled out to a launch pad earlier this week to check ground support systems. The Angara is planned to launch from both Plesetsk and the new Vostochny space center in Russia’s Far East that is being built to reduce reliance on the Baikonur launch facility in Kazakhstan. The modular launcher will have a variety of configurations to cover a wide range of payload weights, from two to 24.5 metric tons. They are currently served by several different rockets, including the Proton, Russia’s largest booster.

That first test launch will be a revealing event, as this is the first completely new Russian rocket in almost a half century. The last time they built a new rocket stage, the Briz-M upper stage for the Proton rocket, they had several significant failures before they worked out all the kinks.

And in a related story, Russia’s deputy prime minister made it clear on Wednesday that his country’s spacecraft manufacturers will face stiffer penalties for any failure to meet production deadlines.

An Audit Chamber report in July last year concluded that the country’s space industry was ineffective and plagued by poor management and misuse of funds. It said Russia had only launched 47 percent of the required number of satellites between 2010 and 2012.

Both stories are revealing by their emphasis on keeping Russia commercially competitive. Note however that Russia recently consolidated its entire space industry into a single entity run by the government. Though I doubt it, we shall find out if this Soviet-style strategy can compete with American-style competition and private enterprise.
