The first chemical analysis of Comet 67P/C-G’s coma

8:30 am

The Rosetta science team today released their first analysis of the chemical make-up of Comet 67P/C-G’s coma, finding that not surprisingly it is made up mostly of water, carbon monoxide, and carbon dioxide.

However, ROSINA [the instrument on Rosetta for doing this analysis] has made the surprising observation that the ratio between these species varies quite significantly, depending on where in the coma Rosetta is. Sometimes carbon monoxide is almost as abundant as water; sometimes it’s only around 10%. In addition, ROSINA has not only detected these main species already, but many of the expected minor ones, such as ammonia, methane, and methanol.

Europe’s satellite makers want Ariane 6

8:50 pm

Europe’s six biggest satellite makers have written Arianespace to demand that the company build its next generation Ariane 6 rocket by 2019 or face a significant loss of business.

Given the advent of electric propulsion and the dramatic launch-cost reduction offered by Space Exploration Technologies Corp., the operators say, the new Ariane 6 needs to be in service by 2019 or face the risk that Europe’s Arianespace launch consortium will be permanently sidelined. The letter was signed by six members of the European Satellite Operators Association. Signatories included the chief executives of Intelsat, SES, Eutelsat, Inmarsat, Hispasat and HellasSat.

This letter is clearly intended to help prod Arianespace into making a decision on whether to build a new rocket, Ariane 6, or upgrade Ariane 5. Right now the company’s partners have been unable to come to an agreement about what to do.

Another delay at Virgin Galactic

2:21 pm

In an interview with David Letterman this week, Richard Branson admitted that his first flight on SpaceShipTwo will not be in December 2014 but early next year.

Watch the interview at the link. It is very clear that Branson is getting uncomfortable with the situation. He has made these claims too many times without showing any results. Also note the incredible ignorance exhibited by Letterman. A good interviewer has to ask some basic questions, but a good interviewer also needs to have a basic understanding of the subject. Letterman shows us here that he doesn’t know squat.

The Russian takeover of Crimea once again threatens American access to space

10:12 pm

A decision by the Russians to possibly shift astronaut training back to a base in the Crimea, now under their control, could lock American astronauts from future Soyuz flights.

Shifting the survival training to Russian-occupied Crimea will require foreign cosmonauts to accept travel there without Ukrainian visas, an explicit acquiescence to the new diplomatic status of the province. Refusal to attend survival training is equivalent to failing the training, which by existing training regulations is an automatic disqualification for flight certification. No Crimea trip, no space trip.

The Russians have not yet made this shift official, so it is possible it will not become a problem. However, the article outlines many reasons why it makes good sense for the Russians to do it.

Polish and Egyptian teams win first European rover competition

2:29 pm

In Europe’s first college competition to see who could build the best Mars rover, two Polish teams finished first and second, with an Egyptian team coming in third.

The first ever European Rover Challenge (ERC) is over and the Scorpio Team from Wrocław University of Technology can now celebrate their victory over 9 other contestants plus a $1,000 cash prize. The challenge was to design, construct and operate a rover that most successfully complete a number of Mars-exploration themed tasks designed by the organizers. “A year of hard work is now finally fulfilled,” said Jędrzej Górski of the Scorpio Team. “Our efficiency is the result of our cohesive team.” The second spot was secured by Polish crew also, the Impuls Team from Kielce University of Technology. Lunar and Mars Rover Team from Cairo University in Egypt scooped the 3rd place. A special bonus award was given to the Robocol Team of Universidad de los Andes (Colombia). ERC 2014 took place in Podzamcze, Poland on Sept. 5-7.

Another launch contract for SpaceX

9:24 am

The competition heats up: In a deal to build Bulgaria’s first communications satellite, Space Systems/Loral has contracted SpaceX’s Falcon 9 as launch vehicle.

The article makes a point of noting that the deal was financed by the U.S. Export-Import Bank, a detail that has in the past almost never been mentioned. The Ex-Im Bank however faces almost certain shutdown because of opposition in Congress, so this mention might be part of a vain attempt to save it.

Arianespace signs four new contracts

7:37 pm

The competition heats up: As a result of lowering its prices to compete with SpaceX, Arianespace on Monday announced four new launch contracts for lighter weight commercial satellites.

At a press briefing here during the World Satellite Business Week conference, organized by Euroconsult, Arianespace said the contracts illustrate the company’s ability to win business in head-to-head competition with what has become its principal competitor, Space Exploration Technologies Corp. and the Falcon 9 rocket. Individual satellite operators choose satellite and rocket suppliers using a range of criteria including schedule, price, recent launch record and export credit-agency financing.

It was not immediately clear how many of the latest satellite wins for Arianespace followed competitions in which SpaceX offered bids compatible with customer specifications and still lost.

These satellites will be launched in the lower berth of the Ariane 5 rocket, which launches two satellites with each launch. Thus, these contracts — while encouraging for Arianespace — still leave the company with the need to find customers to fill that upper berth.

Construction completed on first Orion capsule

7:32 pm

NASA has released the first photo of the completed first Orion capsule, now finished and scheduled to do a test flight in December.

As interesting as that first test flight will be, launching the capsule to about 3,600 miles before it dives back into the atmosphere to test its heat shield, I can’t get that excited about it. I sincerely believe this program will go the way of Ares, the Orbital Space Plane, Constellation, and a host of other big NASA projects that were too expensive and took too long to build. It will get cancelled before it actually flies any humans anywhere.

Another Falcon 9 launch success

9:31 am

The competition heats up: SpaceX has successfully launched its second commercial Asiasat satellite into orbit in just over a month.

“These two satellites launching a month apart are really growth satellites for us,” [William Wade, AsiaSat’s president and CEO] said. “They’re not replacements. They’re new, incremental growth satellites for us across Asia, with C-band on AsiaSat 6 mainly in China, and Ku-band on AsiaSat 8, which was mainly for the Indian subcontinent as well as the Middle East.”

AsiaSat paid SpaceX $52.2 million for each of the launches, according to regulatory filings. [emphasis mine]

As has been noted frequently, that price of $50 million per launch is anywhere from half to a quarter what other companies have been charging. Asiasat got a great deal, and every commercial satellite and launch company in the world is aware of this.

Indecision in Europe about their future commercial rocket

5:57 pm

The competition is burning them up! With Germany and France unable to come to an agreement about the next Arianespace commercial rocket, the company is considering cancelling a December conference that was supposed to settle the issue.

The basic division remains despite the German government’s alignment with the French view that Europe needs a lower-cost rocket to maintain its viability in the commercial market — which in turn provides European governments with a viable launch industry.

Despite the consensus over the longer term, the two sides remain split on whether European Space Agency governments should spend 1.2 billion euros ($1.6 billion) to complete work on a new upper stage for the existing Ariane 5 rocket, which could fly in 2018-2019, or abandon the upgrade to focus spending on a new Ariane 6 rocket, whose development would cost upwards of 3 billion euros over 7-8 years. [emphasis mine]

Though SpaceX is not mentioned in this particular article, numerous previous articles on this subject (such as this one) have made it very clear that it is SpaceX’s low prices that are driving the need for Arianespace to cut costs. The problem, as this article makes very clear, is that Arianespace’s partners can’t figure out how to do it, at least in a manner that will still provide them all an acceptable share in the pie. The result might be that the entire partnership falls apart.

Sarah Brightman, astronaut

9:01 am

The competition heats up: The start of Sarah Brightman’s astronaut training has been delayed from this fall to the beginning of 2015.

I suspect this delay has more to do with accommodating her schedule and the fact that she is very enthusiastic and well-prepared than any negative issues related to her or the mission. They have probably decided that she just needs less time to train.

Her actual flight to ISS is scheduled for the fall of 2015.

Review panel approves extensions for seven planetary missions.

5:19 pm

In approving extensions of seven NASA planetary missions, a review panel concluded that the Curiosity rover wasn’t doing the best it could, and that the project scientist didn’t work hard enough to change their minds.

The Mars Science Laboratory’s Curiosity rover landed on the red planet in August 2012. Equipped with a drill to gather surface samples and spectroscopy equipment to analyze the samples, the rover has collected and analyzed five surface specimens so far and, according to the extended mission proposal just approved by NASA, would analyze another eight over the next two years. That is “a poor science return for such a large investment in a flagship mission,” a 15-person senior review panel chaired by Clive Neal, a geologist at the University of Notre Dame in South Bend, Indiana, wrote in a report published Sept. 3.

The report also chided John Grotzinger, the lead Curiosity project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California, for neglecting to show up in person during a Mars-focused senior review panel meeting in May. “This left the panel with the impression that the [Curiosity] team felt they were too big to fail,” the senior review panel wrote.

This sounds like a pissing war between scientists. Grotzinger didn’t give them the required deference so they slammed him. No matter happened, however, we know they weren’t going to cancel Curiosity’s funds.

Vladimir Putin, space cadet

9:38 am

Two news stories today demonstrate without question that Russia’s newly reorganized aerospace industry and its project to build a new spaceport are not merely the efforts of mid-level bureaucrats in that aerospace industry.

No, these efforts have been instituted and are being pushed at the very top of the Russian government, by Vladmir Putin himself. It appears that he has decided, or has always believed, that Russia deserves a strong and vibrant space program, run from Moscow, and is doing everything he can to make it happen, as part of his personal vision for Russia.

The first story described a visit on Tuesday that Putin made to Russia’s new space port, Vostochny, in the far eastern end of Russia. While there he noted that construction is several months behind schedule and that this slack must be made up. He then endorsed the proposal put to him by space agency officials that the number of people working on construction should be doubled.

The second story described Putin’s endorsement of the construction of a new Russian heavy lift rocket, capable of putting 150 tons into orbit. Such a rocket would be comparable in power to the largest version of the U.S.’s SLS rocket, not due to be launched, if ever, until the 2020s.

Musk vs Bezos

9:08 am

The competition heats up: SpaceX is challenging a patent issued to Jeff Bezos’ Blue Origin for landing the first stage of a rocket vertically on a floating platform.

“The ‘rocket science’ claimed in the ‘321 patent was, at best, ‘old hat’ by 2009,” says SpaceX in one of two challenges, filed last week with the U.S. Patent Trial and Appeal Board following the approval of the Blue Origin patent in March. SpaceX cites prior work by researchers and scientists who proposed techniques similar to those in Blue Origin’s patent.

If the patent holds it might force SpaceX to pay Blue Origin for the right to bring its Falcon 9 first stage back safely,

All geckos lost from Foton-M4

8:47 am

Upon the return to Earth today of Russian biology satellite Foton-M4 biologists discovered that all the geckos on board had died sometime during the mission.

The cause of death has not yet been announced. The mission itself had some problems, and returned to Earth about two weeks early. Nonetheless, the Russians also announced that flies on board were still alive upon landing.

Battle of the heavy lift rockets

9:44 am

Check out this very detailed and informative look at unstated competiton between NASA’s SLS rocket and SpaceX’s heavy lift rocket plans that are even more powerful than the Falcon Heavy.

Key quote: “It is clear SpaceX envisions a rocket far more powerful than even the fully evolved Block 2 SLS – a NASA rocket that isn’t set to be launched until the 2030s.”

The SpaceX rocket hinges on whether the company can successfully build its new Raptor engine. If they do, they will have their heavy lift rocket in the air and functioning far sooner than NASA, and for far far far less money.

Opportunity to get a reboot

9:32 am

Because of an increasing number of computer resets on the Mars rover Opportunity, engineers plan to reformat the rover’s computer.

The resets, including a dozen this month, interfere with the rover’s planned science activities, even though recovery from each incident is completed within a day or two.

Flash memory retains data even when power is off. It is the type used for storing photos and songs on smart phones or digital cameras, among many other uses. Individual cells within a flash memory sector can wear out from repeated use. Reformatting clears the memory while identifying bad cells and flagging them to be avoided.

Obviously there is a risk, though small, that this action will not work and the mission will end here. Stay tuned.

The decision on manned spaceflight

9:23 am

The rumors are swirling. Today alone the news included three different articles about NASA’s upcoming decision to down-select to either one or two in its manned commercial crew program.

The third article above speculates that the decision will be made shortly after this weekend, maybe as soon as next week. It also outlines in nice detail the companies who are competing for the contract.

I strongly expect NASA to pick two companies, not one, as the agency has repeatedly said it wants to have redundancy and competition in manned space flight. To this I agree whole-heartedly. Right now, if I was a betting man (which I am not), I would pick SpaceX and Sierra Nevada as the two companies to get the nod.

If NASA only picks one company that I don’t think there is much doubt that it will be SpaceX.

And then again, government agencies, because of politics, have sometimes made some incredibly stupid decisions. For example, back in the 1970s the company that proposed the space shuttle was rejected for another big space company that had more political clout, which then turned around and essentially stole the first company’s designs to build the space shuttle from them. It just took longer and cost more.

The X-37B just keeps going.

2:56 pm

The Energizer bunny of space: The X-37B has now completed more than 600 days in orbit, with no indication when it will return to Earth.

The Air Force is believed to have only two X-37B space planes. These space planes have flown at otal of three missions, which are known as OTV-1, OTV-2 and OTV-3. (“OTV” is short for Orbital Test Vehicle.) The first mission blasted off in April 2010, and the craft circled Earth for 225 days. The second X-37B vehicle launched in March 2011, performing the OTV-2 mission. This spaceflight lasted 469 days, ultimately landing at Vandenberg Air Force Base in California in June 2012. That was the same landing site OTV-1 used after completing its mission.

The current OTV-3 mission is reusing the first X-37B space plane from the OTV-1 flight, showcasing the reusability aspect of the program.
