Europe settles on Ariane 6 design

6:47 pm

The competition heats up? Airbus Safran and the European Space Agency have settled on the design of their next generation rocket, Ariane 6.

It will not be re-usable, and though they say it will be 40-50% cheaper to produce than Ariane 5, it is very clear from the quotes in the article that they are instead depending on trade restrictions to maintain their European customers, even if it costs them a lot more to put satellites in orbit.

For its part, Airbus Safran does not envisage making Ariane 6 recoverable, not in the short term. Mr Charmeau [the company’s CEO] believes that different market conditions apply in Europe and the US, which means there will not be a single, winner-takes-all approach. He cites, for example, the restricted procurement that exists in all major political blocs, which essentially bars foreign rockets from launching home institutional and government satellites. Nowhere is this more true than in the US, but in Europe too there is an “unwritten rule” that European states should use European rockets.

From an American perspective this lazy attitude is fine with me. Let American companies compete aggressively. They will then leave the Europeans and everyone else in the dust.

Private company proposes commercial airlock for ISS

10:01 am

The competion heats up: The private company NanoRacks has proposed building a large airlock for ISS which could be used to launch private cubesates while also allowing NASA to eliminate spacewalks by bringing faulty equipment inside for repairs.

For commercial opportunities, NanoRacks has a small satellite launcher, and it is also designing a “haybale” system to launch as many as 192 cubesats at a time. After the airlock is configured, it would be depressurized and sealed. Then a station robotic arm could grab it, move it away from the vehicle, and deploy its payloads.

NASA is also interested in the opportunity to potentially fix large, external components of the space station. Before the space shuttle’s retirement, NASA used the sizable delivery vehicle to stash dozens of replacement pumps, storage tanks, controller boxes, batteries, and other equipment on the station, known as ORUs. When one of these components broke, astronauts would conduct a spacewalk to install a replacement unit.

However sometimes the problem with a broken unit is relatively minor, such as a problematic circuit card. With a larger airlock, damaged components could be brought inside the station, assessed, and possibly fixed, saving NASA the expense of building and delivering a new unit to the station—or losing a valuable spare. Finally, the space agency could use the airlock to dispose of trash that accumulates on station and can be difficult to get rid of.

It is exactly this kind of technology, spurred by the lure of profits, that interplanetary spaceships need if they are going to be maintainable far from home.

McCain and Air Force question ULA military arrangement

9:53 am

On Wednesday, the military arrangement between the Air Force and ULA came under strong attack.

First, Senator John McCain (R-Arizona) and House Majority Leader Kevin McCarthy (R-California) introduced a bill in Congress that would re-instate the ban on ULA’s use of Russian engines in the Atlas 5 rocket. The ban had been lifted when Senators Richard Shelby (R-Alabama) and Richard Durbin (D-Illinois) snuck language doing so into the giant omnibus budget bill in December.

Second, at a hearing in the Senate on Wednesday, Air Force, under attack by Senator McCain for its sweetheart deal which gives ULA $800 million annually whether or not it launches anything regardless, admitted that it is thinking of terminating that deal early.

Air Force Secretary Deborah Lee James told the Senate Armed Services Committee during a Wednesday hearing the service is considering early termination of the current EELV Launch Capability (ELC) contract, a unique arrangement set up in 2006 to fund the cost of maintaining ULA launch infrastructure. At the time, the arrangement made sense because ULA was the Pentagon’s sole source for military space launch. “I was very surprised and disappointed when ULA did not bid on a recent GPS competitive launch opportunity,” James said. “And given the fact that there are taxpayer dollars involved with this ELC arrangement I just described to you, I’ve asked my legal team to review what could be done about this.”

The McCain bill is not likely to pass. However, the pressure he is putting on the Air Force, combined with the renewed and cheaper competition being offered by SpaceX, could very well lead to the ending of ULA’s EELV deal.

I expect to see a similar scenario play out in connection with Orion/SLS sometime in the next two years. When SpaceX and others begin to fly manned capsules and big rockets for relatively little money, our elected officials are eventually going to notice how much more expensive that bloated government program is, even as it doesn’t accomplish much. Some of them will suddenly realize the political advantage in attacking SLS, and begin to do so.

Air Force certifies Falcon 9 upgrade for military launches

6:35 pm

The competition heats up: The Air Force has approved use of SpaceX’s upgraded Falcon 9 rocket for use in military launches.

What this means is that SpaceX is increasingly considered an acceptable bidder for future military launch contracts. Moreover, it means that SpaceX will be able to use the Falcon 9 first stage that they are landing vertically, giving them more recoverable first stages for future flights.

Blue Origin to increase New Shepard launch rate

6:32 pm

The competition heats up: Blue Origin expects to increase the rate of test flights for its New Shepard reusable rocket in 2016.

“We expect to shorten that turnaround time over time this year, and fly this vehicle again and again,” [Blue Origin President Rob Meyerson] said. Those upcoming tests will use the same New Shepard vehicle that flew the previous two flights, with hardware and software modifications as needed between flights. Meyerson said the company still plans to perform “dozens” of test flights of New Shepard over the next couple of years before the company is ready to carry people on the vehicle. “It really depends on how the flight test program goes,” he said. “It could be a little faster than that, or it could be a little longer than that, depending on what we learn.”

I expect that by the end of 2016, the U.S. will have two proven reusable first stage rockets and two operational orbital cargo spacecraft. And that doesn’t count the likely first demo flight of Falcon Heavy.

Comet 67P/C-G’s active surface

9:28 am

Comet 67P/C-G's active surface

Cool image time! The Rosetta science team today released a spectacular image, taken by Rosetta’s high resolution camera, of the surface of Comet 67P/C-G. A cropped version is above and below the fold. A cropped version of the full image, focusing in on the smooth and active area dubbed Imhotep, is above.

This smooth dusty terrain, which covers about 0.8 sq km, is etched with curvilinear features stretching hundreds of metres and which have been found to change in appearance over time. Many large boulders are also seen scattered within the smooth terrain, including the boulder Cheops in the foreground. Smaller but more numerous boulders are associated with exposed cliff faces and are most likely the product of erosion. In some debris falls, detailed analysis has revealed the presence of water ice.

I have also included, below the fold, a second close-up crop from this same image, showing the layered cliffs to the left of Imhotep as well as several mysterious as-yet not understood round features at the cliff’s base.

Blue Origin reflies and lands New Shepard again

8:53 am

The competition heats up: Blue Origin yesterday successfully re-flew its New Shepard booster, vertically landing it for the second time.

Data from the November mission matched our preflight predictions closely, which made preparations for today’s re-flight relatively straightforward. The team replaced the crew capsule parachutes, replaced the pyro igniters, conducted functional and avionics checkouts, and made several software improvements, including a noteworthy one. Rather than the vehicle translating to land at the exact center of the pad, it now initially targets the center, but then sets down at a position of convenience on the pad, prioritizing vehicle attitude ahead of precise lateral positioning. It’s like a pilot lining up a plane with the centerline of the runway. If the plane is a few feet off center as you get close, you don’t swerve at the last minute to ensure hitting the exact mid-point. You just land a few feet left or right of the centerline. Our Monte Carlo sims of New Shepard landings show this new strategy increases margins, improving the vehicle’s ability to reject disturbances created by low-altitude winds.

They are not clear whether the capsule was re-flown as well. They do say they intend to re-fly New Shepard many times in 2016, probably at an increasing rate. If so, I would say that the race to be the first to sell suborbital tickets to tourists is won by Blue Origin, and that Virgin Galactic and XCOR have been left in the dust.

I have embedded the company’s video below the fold of yesterday’s flight.

Europe kicks in money for Dream Chaser

2:54 pm

The competition heats up: NASA’s decision to award Sierra Nevada a cargo contract has triggered a $36 million investment by the European Space Agency (ESA) to build a new docking unit for Dream Chaser at ISS.

Sierra Nevada Corp.’s win of a NASA contract to ferry cargo to the International Space Station will trigger a $36 million investment by the 22-nation European Space Agency following a cooperation agreement to be signed in the coming weeks, ESA said. Once the agreement is signed, ESA will begin work building the first flight model of the International Berthing and Docking Mechanism (IBDM), which Sierra Nevada’s Dream Chaser Cargo System will use to attach itself to the space station.

ESA said it would spend 33 million euros ($36 million) to complete the design of the IBDM and build a flight model for Dream Chaser’s first cargo run. Future IBDMs will be financed by Sierra Nevada, ESA said.

Angara at Vostochny trimmed

10:16 am

Due to cuts in the Russian government’s ten-year plan for aerospace, the number of Angara launchpads at the new Vostochny spaceport has been slashed in half, with construction delayed as well.

On January 20, 2016, Roskosmos officials admitted that budget cuts at the end of 2015 required to drop plans to build one of the two launch pads for Angara rockets in Vostochny. Previously, the Russian space officials claimed that a dual launch complex for the Angara was absolutely necessary to support the four-launch scenario of the lunar expeditions relying on the Angara-5V rocket. The beginning of the construction of the remaining single pad was now delayed from 2016 to 2017.

Based on all the different reports I’ve read, they have also eliminated in the 10-year plan all lunar missions and the construction of a new space station. Essentially, their budget can only barely sustain what they are already doing. Like NASA, they have too large a labor force — jobs maintained for pork barrel reasons rather than actually accomplishing anything — that makes it impossible for them to afford anything new.

Orion: construction in slow motion

9:57 am

Today NASA announced completion of the welding of the next Orion capsule, a job that this story said took about three months to do 7 welds. The story also noted this:

After putting on the finished touches, NASA plans to ship the vehicle to the Kennedy Space Center (KSC) aboard NASA’s Super Guppy airplane on or about Feb. 1. At KSC, engineers working inside the Neil Armstrong Operation and Checkout Building (O & C) will spend the next two years outfitting Orion for launch in late 2018 by installing all the systems and subsystems for its inaugural flight to the Moon and back.

Overall this is the third Orion capsule that NASA has built, following the Ground Test Article (GTA), which did not fly, and the EFT-1 capsule which successfully launched just over one year ago on Dec. 5, 2014. [emphasis mine]

Three months to do 7 welds. Two years to outfit a capsule. Wow! At that pace they might launch before the end of the century.

Seriously, this is an absurdly slow work pace, illustrating the wasteful nature of the SLS/Orion program. Orion’s budget these days is about $1 billion per year, with a total cost expected to reach $17 billion by the time the fourth capsule is built and launched in 2023, for a project first proposed in 2004.

In other words, it will take NASA and Lockheed Martin almost 20 years to build four capsules for the cost of $17 billion. That is absurd. Compare it to commercial space: The entire budget for all the commercial crew contracts, including both cargo contracts and the manned contract, is about half that, and will produce four different vehicles, all of which will be built and flying by 2019 at the latest. And in the case of Dragon and Cygnus, more than a dozen capsules have already flown.

Is there no one in Washington with the brain power to read these numbers and come to a rational decision about SLS/Orion? It costs too much and isn’t getting us into space. Moreover, at its pace and cost it isn’t doing anything to help the American aerospace industry. Better for Congress to put money into other things, or save it entirely and reduce the deficit and thus not waste it on this pork barrel garbage.

Unfortunately, our elected officials today not only don’t have brains, too many of them are downright corrupt. They prefer to bankrupt the nation for their own petty gain rather than do things that might help the nation grow.

Video of Dragon/SuperDraco engine test

9:20 am

The competition heats up: SpaceX today released a video of a five second test they did in November of the SuperDraco thrusters attached to their Dragon capsule.

I have embedded the video below the fold. This test, which took place on a test stand with the capsule hanging from a crane cable, was part of their work to develop a launch abort capability for the manned version of Dragon. The thrusters will also be used eventually to make possible vertical land landings of the capsule.

Dantu Crater on Ceres

11:30 am

bright areas on crater wall on Ceres

Cool image time! As Dawn continues its close survey of Ceres, the science team has released this image of Dantu Crater, showing the bright spots on its rim as well as fractures on the crater floor. The picture was taken in December and has a resolution of about 120 feet per pixel.

Though scientists now favor salt deposits of some kind as the cause of the bright areas on Ceres, they also recognize that this theory is not yet proven. Moreover, the theory suggests that the salt was deposited as part of a water brine. When the water in the brine evaporated away, it left the salt behind. The problem, however, is that we do not yet have direct evidence that there is any water on Ceres at all, either on the surface or in the interior, which makes this theory exceedingly uncertain.

World View gets incentives to settle in Arizona

9:27 am

The competition heats up: The space tourism balloon company World View has obtained $15 million in subsidies from an Arizona county to base their operation in Tucson.

Today’s go-ahead from the Pima County Board of Supervisors represents an initial step toward setting up the tourist operation. The supervisors voted to invest $15 million, backed by future tax revenue, to build the spaceport. World View would lease the facility from the county over a 20-year term to pay back the investment. The facility would include a launch pad, headquarters building and manufacturing facility, World View said.

Increasingly it looks like Virgin Galactic’s SpaceShipTwo is being left in the dust as other companies move forward with their own plans.

Astronomers propose Neptune-sized planet in Kuiper Belt

9:13 am

The uncertainty of science: Using the orbital data of many recently discovered Kuiper Belt objects [KBOs], two astronomers have proposed the existence of a planet ten times the mass of the Earth and orbiting the sun every 20,000 years.

Trujillo and Sheppard had noted that Sedna, VP113, and several other KBOs all shared a peculiar property: their closest approach to the Sun lay in the plane of the Solar System, and they all moved from south to north when crossing that plane. Batygin and Brown analyzed the orbits further and discovered that their long axes were physically aligned, too, as if something had nudged them to occupy the same region of space around the Sun. The team concluded that a massive object must be shepherding the objects. “We have a gravitational signature of a giant planet in the outer Solar System,” Batygin says.

Planet Nine — informally known as Phattie — is probably smaller than Neptune and icy with a gassy outer layer. The gravitational effect of Uranus and Neptune would have flung it outward in the first 3 million years of the Solar System’s existence, Batygin says.

Be warned! The existence of this as-yet unseen giant planet is quite uncertain. The orbits of the KBOs they are using to postulate its existence have only been observed for a very short period and have not been completely mapped. Thus, those orbits themselves are very uncertain. Moreover, we so far have a very incomplete census of the Kuiper Belt. The orbital behavior used as evidence of another planet could also be caused by many other known factors that have not yet been observed.

Tuesday’s Batchelor podcast

10:38 pm

Below the fold is the podcast of my appearance on the John Batchelor Show today, Tuesday. It was fun comparing the recent successes of private space compared to the big space programs of the U.S., Russia, and China. I also made reference to this essay I wrote after watching Elon Musk first announce in 2011 his plans to vertically land the first stage of his Falcon 9 rocket. Took him only five years to do it.

The Falcon 9 first stage almost landing

10:50 pm

I can’t resist. I have to post that video here of the Falcon 9 first stage landing and then falling over from Sunday. You can see it below the fold. It is incredibly impressive, because it shows that the stage actually did succeed in landing, though a failure of some kind afterward caused it to tip over. The company says it was the failure of one landing leg, but if you watch the video you can see that the angle of fall is between two legs, which suggests that the cause was more complicated.

Nonetheless, don’t be surprised if by the end of 2016 SpaceX is successfully landing its first stages on every launch.

Russia names next manned spaceship “Federation”

7:44 pm

They might not be close to building it, but the Russian government has decided that the name they will use for their next generation manned spaceship to replace Soyuz will be “Federation.”

“Federation is a perfect name for the series of new Russian spacecraft. Russia is a federation of 85 constituent entities and each of them will be able to give its name for one of the spaceships,” the corporation [Energia] said [in a press release].

Don’t bet on this spaceship appearing in the near future. In fact, don’t bet on it having this name either. Remember how in the 2000s they were going to build “Clipper”? That never happened either. With a shrinking economy and the consolidation of their entire aerospace industry into a single government entity I expect Russia’s space industry to have a great deal of problems building anything new in the coming years.

Falcon 9 launches NASA satellite, first stage landing fails

7:30 pm

The competition heats up: SpaceX successfully put its first NASA/NOAA science satellite in orbit today, though its attempt to land the Falcon 9 first stage on a barge failed when one landing leg broke and the stage tipped over.

The first stage however was still recovered as it fell sideways on the barge. The link above includes a picture, which shows that stage lying on its side. The engines might be recoverable, but certainly they have enough material from the stage to do tests and learn a great deal more about how it tolerates the stresses of launch. Commenter Frank provides a link to a video that shows the stage falling over and exploding, something the images I had seen previously had not shown. They might have more material to test, but hardly as intact as I had first thought.

Nonetheless, they have now successfully test fired the engines from last month’s recovered first stage.

The 156-foot first stage booster that carried out that successful landing was taken to the company’s hangar at Launch Complex 39A at NASA’s Kennedy Space Center in Florida and partially inspected. It was later taken back to Launch Complex 40 and hoisted upright via a crane. On Jan. 15, a static fire was conducted. “Data looks good overall,” Musk said in a tweet, but noted Engine No. 9—one of the outer engines—showed thrust fluctuations. He said that there may have been some debris ingestion, but the engine data looks OK and that they would borescope later that night. There has been no word on how that inspection went.

That all nine engines functioned is a very good sign, even if one had issues.

Spacewalk cut short due to spacesuit water leak

10:50 am

Today’s spacewalk at ISS to repair a failed voltage regulator of the station’s power system has been cut short because a water bubble had appeared inside one of the astronaut’s spacesuit.

The astronauts are presently in the airlock about to remove their spacesuits, so it appears they are not in danger. However, this problem is the return of the earlier water leaks inside NASA’s spacesuits, something that the agency had thought it had solved last year. If it has returned, this is of serious concern, since it suggests that they have not yet pinpointed the chronic cause of the problem.

It should be noted that the astronauts had successfully replaced the voltage regulator prior to the premature conclusion of their spacewalk. They had had other less critical tasks on their schedule which they had to forego because of the leak.

Russia trims its 10-year space plan

10:28 pm

The competition cools: Due to budget pressures, Russia has once more cut what it plans to do in its as yet not finalized 10-year space plan.

Not only do they expect to fly fewer satellites during the plan, they appear to either have dropped or are significantly curtailing their plans for their own space station after they pull out of ISS in 2024.

The corporation has also lost some of the original ambitious projects, including creation of two autonomous modules (transformable and power generating ones, ordered by the Russian Academy of Sciences), meant for the creation of a Russian orbital station. The project is absent from the latest version of the program. A transformable module was to be created in 2020-2025 and its launch was scheduled for 2025. Its service life was estimated at five years and design and manufacturing costs, 12.3 billion rubles.

In addition, it appears they are cutting back their plans for planetary research.

Bush, Cruz, Carson, and Sanders on space policy

10:04 am

This article takes a look at the positions on space policy of four candidates for President.

Not surprisingly, there is not much substance to what these candidates have said. They mostly mouth positive platitudes about space, and often indicate by those platitudes a general lack of knowledge about the subject.

What is more important to consider is their overall political philosophies combined with legislative actions they have actually done. Cruz for example is clearly in favor of reducing the cost and size of government. He has also made it clear by his actions in the Senate that he considers space an important national priority. These facts tell me that, should he become president he will likely move to end SLS while shifting resources to private space, since it costs a lot less and the government (and nation) will get more for its money.

Sanders meanwhile has consistently voted for a smaller space program in all his years in the Senate. As a socialist and a liberal who sides with the Democrats routinely, he, like them, has generally opposed spending any money on NASA or space, generally arguing that the money would be better spend solving problems on Earth. While he might mouth support for NASA now, I would expect him to try to kill it once in office.

Orbital ATK and SpaceX win Air Force contracts

9:42 am

The competition heats up: The Air Force has awarded Orbital ATK and SpaceX contracts to develop new rocket engines to help end the U.S.’s reliance on Russian rocket engines.

The Orbital contract is initially worth $47 million, with the company committed to spend $31 million of its own money., according to the Defense Department’s daily digest of major contract awards. Eventually the government could pay the company $180 million. SpaceX’s contract meanwhile was for $33.6 million initially for the development of its new Raptor upper stage engine, with a total government payment to be $61 million.

And that’s not all. Later today NASA will announce the winners in its second ISS cargo contract. The competitors are SpaceX, Orbital ATK, and Sierra Nevada. I am hoping the latter two win, since that would allow the construction of a fourth American spacecraft, Sierra Nevada’s Dream Chaser, capable of lifting cargo and crew into space.

Juno becomes most distant solar-powered mission

9:34 am

Scheduled to enter orbit around Jupiter in July 2016, the American space probe Juno has now broken the record as the most distant solar-powered interplanetary spacecraft ever to operate.

The previous record had been held by Rosetta. In the past most missions beyond Mars used nuclear-generated power plants, since the amount of sunlight is insufficient. However, improvements to the efficiency of solar power, combined with a lack of nuclear fuel in the U.S., has made it possible to fly missions using solar power farther from the sun.
