Arianespace and ESA sign contract for three launches

9:53 am

Arianespace and the European Space Agency (ESA) signed a contract on Thursday for the Ariane 5 rocket to launch 12 more of Europe’s Galileo GPS satellites on three launches.

This contract is a perfect example of European pork. Europe’s Galileo system might provide competition to the U.S. GPS and Russian Glonass systems, but I am not sure what additional capabilities it provides that will convince GPS users to switch to it. Instead, building it provides European jobs, while using the Ariane 5 rocket to launch it gives that increasingly uncompetitive rocket some work to do. In fact, this situation really reminds me of the U.S. launch market in the 1990s, when Boeing and Lockheed Martin decided that, rather than compete with Russia and ESA for the launch market, they instead decided to rely entirely on U.S. government contracts, since those contracts didn’t really demand that they reduce their costs significantly to compete.

Europe now appears to be heading down that same road.

NASA’s Space Launch System searches for a mission

9:26 am

Managers of NASA’s Space Launch System (SLS) are searching for a mission that they can propose and convince Congress to fund.

Any honest read of this article will conclude that this very expensive rocket system is an absurd waste of money. It has no mission now, and will never get one considering the cost. Instead, NASA will spend billions to fly two test flights, both unmanned, and then the money will run out.

Sierra Nevada abandons its own hybrid engine for Dream Chaser

1:13 am

The competition heats up: Sierra Nevada has decided not to use its own hybrid engine on its Dream Chaser manned shuttle.

With the apparent decision by Virgin Galactic to also abandon this engine, it would appear that hybrid rocket technology is not yet ready for prime time, if ever.

Posted from Spokane, Washington, where Diane and I will be visiting my oldest friend Lloyd and his family for the rest of the week.

Orbital plans upgrade to Antares

1:00 am

The competition heats up: On its next cargo mission to ISS Orbital Sciences plans on launching an upgraded Antares rocket.

For its third paid cargo mission to station, slated to launch Oct. 21, Orbital will replace the ATK Castor 30B Antares used for its latest launch with an ATK Castor 30XL. The upgrade will allow Cygnus to carry about 2,290 kilograms of cargo to station — an increase of nearly 40 percent by mass, compared with the second mission, according to Orbital’s Aug. 18 press release.

The Castor 30XL is the latest in the Castor 30 series ATK developed specifically as an Antares upper stage. A pair of Antares demonstration launches in 2013, which did not count toward fulfilling the company’s delivery-and-disposal contract with NASA, used the Castor 30A. ATK has lengthened subsequent versions of the motor, squeezing more power out of it by packing it full of more solid fuel.

Like SpaceX, Orbital Sciences is demonstrating the ability here to do operational missions simultaneously with developmental missions.

Curiosity retreats from Hidden Valley

3:27 pm

Finding its sandy floor slipperier than expected, engineers have backed Curiosity out of Hidden Valley to drill some holes while they reassess the rover’s route.

The rover’s wheels slipped more in Hidden Valley’s sand than the team had expected based on experience with one of the mission’s test rovers driven on sand dunes in California. The valley is about the length of a football field and does not offer any navigable exits other than at the northeastern and southwestern ends. “We need to gain a better understanding of the interaction between the wheels and Martian sand ripples, and Hidden Valley is not a good location for experimenting,” said Curiosity Project Manager Jim Erickson of JPL. …

Curiosity reversed course and drove out of Hidden Valley northeastward. On the way toward gaining a good viewpoint to assess a possible alternative route north of the valley, it passed over the pale paving stones on the ramp again. Where a rover wheel cracked one of the rocks, it exposed bright interior material, possibly from mineral veins.

More and more, the journey to Mount Sharp appears to be increasingly adventurous for the rover.

Competition with SpaceX forced ULA CEO out

8:59 am

A news story today in Defense News speculates that the competitive pressure from SpaceX is what forced ULA’s CEO to step down.

Changes at the CEO level are usually accompanied by a change in how business is done, said Byron Callan, an analyst with Capital Alpha Partners. “Generally, when you see abrupt leadership changes, there’s an abrupt change of strategic or tactical course needed,” Callan said. “You don’t make those changes unless you see something that needs fast corrective action.”

Caceres said he expects to see layoffs and a streamlining of ULA to find all possible cost savings. “My sense is you’re going to see at ULA a restructuring of some sort, because ultimately they’re going to have to find a way to be a lot more competitive on price,” he said.

This restructuring is entirely the result of the new competition from SpaceX, as repeatedly noted by the article.

Branson insists he will fly this year

8:54 am

In an interview for USA Today Richard Branson once again repeated his expectation that he will fly in space on SpaceShipTwo before the end of the year.

It sounds like they plan three test flights with their new engine, followed by Branson’s public relations stunt. Even if this plan happens, however, I do not see them ready to fly paying passengers, as they will probably need more test flights to make sure the ship and its engine are truly trustworthy.

Russia to build new satellite communications cluster

10:06 am

The competition heats up: The Putin government’s newly released draft plan for Russia’s space industry includes the development of a new communications satellite constellation.

In addition to encrypted mobile communications, the Ellips satellites will support air-traffic control and traditional fixed communications. Reflecting its dual (civilian and military) application, the Ellips project would be funded jointly by the Russian space agency, Roskosmos, and by the Russian Ministry of Defense at a price tag of 65.6 billion rubles to develop and deploy the constellation.

The article then goes on to detail at length the problems the Russian communications satellite industry has had for the past two decades, including their inability to build satellites that will last in orbit as long as their competitors.

Another look at why ULA’s CEO stepped down

9:52 am

Why did ULA’s CEO step down, and did SpaceX or the Atlas 5’s dependence on Russian engines play a part?

Very worthwhile reading, as it suggests that not only is the competition from SpaceX a major factor, so was ULA’s effort to monopolize the military launch industry as well as monopolize its access to the Russian engines, denying their use by Orbital Sciences.

And to this I say, thank god for competition. It always shakes things up in a good way.

Worldview-3 in orbit

9:30 am

The competition heats up: Worldview-3, launched yesterday, has been successfully activated and can now provide commercial and private customers images of the Earth with resolution comparable to military intelligence satellites.

The sensor package on WorldView-3 will be able to image objects with a ground sample distance of 31 cm (12 in.). “So we can tell you if it’s a truck, SUV or a regular car,” says Kumar Navulur, director of next-generation products at DigitalGlobe. “If there’s a high contrast we can identify features of fine scale,” he adds, giving examples of markings in a parking lot or “a tomato plant in a backyard in Asia.”

Obviously, this has both good and bad possibilities. Nonetheless, its availability increases the value of the space-based industry.

The flight of gifted engineers from NASA

5:43 pm

Rather than work in NASA, the best young engineers today are increasingly heading to get jobs at private companies like SpaceX and XCOR.

It is a long article, worth reading in its entirety, but this quote will give the essence:

As a NASA engineering co-op student at Johnson Space Center, Hoffman trained in various divisions of the federal space agency to sign on eventually as a civil servant. She graduated from college this year after receiving a generous offer from NASA, doubly prestigious considering the substantial reductions in force hitting Johnson Space Center in recent months. She did have every intention of joining that force — had actually accepted the offer, in fact — when she received an invitation to visit a friend at his new job with rising commercial launch company SpaceX.

Hoffman took him up on the offer, flying out to Los Angeles in the spring for a private tour. Driving up to the SpaceX headquarters, she was struck by how unassuming it was, how small compared to NASA, how plain on the outside and rather like a warehouse.

As she walked through the complex, she was also surprised to find open work areas where NASA would have had endless hallways, offices and desks. Hoffman described SpaceX as resembling a giant workshop, a hive of activity in which employees stood working on nitty-gritty mechanical and electrical engineering. Everything in the shop was bound for space or was related to space. No one sat around talking to friends in the morning, “another level from what you see at NASA,” she said. “They’re very purpose-driven. It looked like every project was getting the attention it deserved.”

Seeing SpaceX in production forced Hoffman to acknowledge NASA might not be the best fit for her. The tour reminded her of the many mentors who had gone into the commercial sector of the space industry in search of better pay and more say in the direction their employers take. She thought back to the attrition she saw firsthand at Johnson Space Center and how understaffed divisions struggled to maintain operations.

At NASA young engineers find that they spend a lot of time with bureaucracy, the pace is slow, their projects often get canceled or delayed, and the creative job satisfaction is poor. At private companies like SpaceX, things are getting built now. With that choice, no wonder the decision to go private is increasingly easy.

It ain’t gravity holding this asteroid together

1:14 pm

Astronomers have discovered that near Earth asteroid 1950DA is spinning so fast that gravity can’t hold it together. Instead, it is kept whole by cohesive forces called van der Waals forces, predicted but never detected before on an asteroid.

This is the coolest factoid from the article, however:

“We found that 1950 DA is rotating faster than the breakup limit for its density,” said Rozitis. “So if just gravity were holding this rubble pile together, as is generally assumed, it would fly apart. Therefore, interparticle cohesive forces must be holding it together.”

In fact, the rotation is so fast that at its equator, 1950 DA effectively experiences negative gravity. If an astronaut were to attempt to stand on this surface, he or she would fly off into space unless he or she were somehow anchored.

The important take away from this discovery is that it will be very easy to break this kind of asteroid up, turning a large and big threat into a collection of small but harmless rocks.

Another former SpaceX employee sues

9:09 am

SpaceX has been hit by its second lawsuit in a week from a former employee.

The lawsuit, filed in Los Angeles Superior Court, alleges that SpaceX supervisors impose schedules on their employees that make it impossible for them to take statutorily required rest periods every four hours or first or second meal breaks as required by California law.

I consider this suit a bigger threat to the company than the first. The first suit merely claimed that the company didn’t give its fired employees the 60 day warning as required by law. If they win, they will get some payments, but the company will be able to continue as before.

This second suit, if successfully, could force the company to change its aggressive culture, where employees are expected to work very hard, sometimes 60-80 hour weeks, to make things happen quickly. While those work hours might seem abusive to some, to most of the people working there it is what they want to do. A successful lawsuit here could force the company to literally stop them from working. The conditions then might be more relaxed, but the ability to make progress will be stymied, and the costs for making that progress will go up considerably.

ULA CEO steps down

4:24 pm

Faced with stiff competition from SpaceX, United Launch Alliance (ULA) announced today a change in leadership.

United Launch Alliance has named a new president and chief executive to replace Michael Gass, who led the Atlas and Delta rocket company since its inception in 2006. Gass will be replaced effective immediately as president and CEO by Tory Bruno, an executive at Lockheed Martin Corp., which formed ULA in December 2006 in a 50-50 joint venture with Boeing Co., ULA said in a statement Tuesday. Gass is retiring at the end of the year, according to ULA.

Despite Gass’s planned retirement, the abrupt nature of his departure has everything to do with the competition from SpaceX, something that every single article about this change at ULA noted.

NASA admits that it is struggling to meet the 2017 launch date for SLS

11:13 pm

Delays in the construction of Orion’s European-built service module as well as cracks in the spacecraft’s heat shield are threatening the planned 2017 launch date for Orion’s first test flight, unmanned, beyond Earth orbit.

Note that this program, costing anywhere from $10 to $20 billion, is only building a handful of capsules for flying three or four test flights. Beyond that, there is no money.

I have predicted this before, and I will predict it again: SLS will never take any humans anywhere. The cost is too high, the bureaucracy too complex, and the schedule is too slow. It will vanish when the new private companies begin flying humans into space in the next three years.

Another Rosetta closeup of 67P/C-G

4:15 pm

67P on August 8

The above image is not the most recent daily image from Rosetta, but it is the most interesting of the last three.

It shows the side of the comet nucleus that has not been featured in most images, as the topographical differences between its two sections is not as distinctly highlighted. What is highlighted is the neck that connects the two sections, lighter colored and thus likely made up of less dusty ice.

Also of interest here is the circular features on the larger bottom section. These certainly resemble craters, and are likely remnants of early impacts that are now been corroded away as the nucleus’s ice particles evaporate off the surface. The scientific question here is this: Why are crater features more evident on this side and section of the comet nucleus than on other areas of its surface?

Test results from NASA saucer Mars landing test

8:09 pm

NASA has released video and test results from the first test flight of its Low-Density Supersonic Decelerator (LDSD), referred by many press outlets as a “flying saucer” because of its shape.

The purpose of the test was to see if the saucer and its parachute would work to slow a vessel down sufficiently in the Martian atmosphere. The parachute tore and failed. The video describes the flight and the failure and how the data from this failure can now be used to modify the parachute for the next two test flights.

The Dream Chaser test vehicle to fly again

10:08 am

The competition heats up: Sierra Nevada has announced that its Dream Chaser engineering test vehicle has been refurbished and will complete a number of manned and unmanned flight tests in the fall, with their schedule on track for a November 2016 orbital test flight.

“We will do between two and five additional flights. A couple will be crewed. As a result of the vehicle being upgraded, we will be flying our orbital flight software, which will give us about a year’s worth of advancement on the vehicle.” Flights are expected to last over a six- to nine-month period, he adds.

Sierra Nevada has also continued to expand its partnerships, both in the aerospace industry as well as with other countries. The first action is likely part of a lobbying effort to help convince NASA to choose it when it down selects its commercial manned program from three manned spacecraft to two later this year. The second action indicates that even if Sierra Nevada is not chosen by NASA, they plan to proceed to construction anyway to serve other customers.

Orion first test flight scheduled

10:00 am

NASA has set December 4 for the first test flight of Orion.

In related news, the Navy has successfully completed a splashdown recovery test of Orion.

I haven’t labeled these stories “The competition heats up” because I have serous doubts Orion or SLS will survive the next Presidential election, even if this test flight on a Delta 4 Heavy rocket is a complete success. And if you want to know why, just read the first article above. It lists the long troubled ten-year long history of this capsule, with the following punchline describing the schedule for further launches with the actual SLS rocket:

While the first SLS/Orion mission, known as EM-1, is still officially manifested for December 15, 2017 – internally that date has all-but been ruled out. Internal schedules shows EM-1 launch date as September 30, 2018, followed by the Ascent Abort (AA-2) test – required for crew launches – on December 15, 2019, followed by EM-2 on December 31, 2020.

I find also find it interesting that in describing the many problems Orion has had in development, the article fails to mention the cracks that appeared in the capsule that required a major structural fix. Nor does the article mention the ungodly cost of this program, which easily exceeds $10 billion and is at least four times what NASA is spending for its entire program to get three different privately built spaceships built in the commercial program.

Dragon launch abort tests scheduled

9:45 am

The competition heats up: SpaceX has scheduled its Dragon launch abort tests for November and January.

The Hawthorne, California-based company plans to conduct a pad abort test at Cape Canaveral Air Force Station, Florida, in November, followed by an in-flight abort test from Vandenberg Air Force Base in California in January, Garrett Reisman, SpaceX Dragon Rider program manager, said here Aug. 6 at the American Institute of Aeronautics and Astronautics Space 2014 conference.

In the pad-abort test, Dragon will be mounted to a mocked-up SpaceX Falcon 9 rocket and use its hydrazine-fueled SuperDraco thrusters to boost itself up and away from the pad, as it might need to do in the event of a major problem just before or during liftoff. The in-flight test will attempt to repeat the feat at altitude.

In related news, two former SpaceX employees who were terminated in July when the company laid off about 400 people in an annual restructuring of its workforce have sued the company for not giving them ample notice as required by California law.

The California law is pretty clear, which means these employees will likely win, which also sounds to me like a good reason to shift SpaceX’s entire operation to Texas and its new spaceport in Brownsville.

67P from 52 miles

9:32 am

67P from 52 miles, August 7, 2014

The image above was taken on August 7 from only 52 miles. For the first time I had to scale it down slightly so that it would fit on the webpage.

My impression with this image is that there actually might be hints of some very ancient craters at several of the vaguely circular pitted features. For example, look at the large feature on the end of the nucleus’s smaller component on the right. This might be a crater that now is significantly eroded as the comet’s surface evaporated away each time it approached the Sun every 6.5 years.

Congress applies pressure to ULA and the Air Force

8:58 am

Two congressional committees are holding up approval of a budget revision for the Air Force’s launch program because of concerns about cost overruns and the program’s dependency on a Russian rocket engine.

Such requests must be approved by each of the four congressional defense committees, and so far, the EELV proposal has won the support of only two. The Senate Appropriations Defense subcommittee and the House Appropriations Defense subcommittee have green-lighted the plan, while the House and Senate Armed Services committees have deferred approval, according to budget documents dated July 25 and July 31, obtained by Defense News.

[The Senate Armed Services Committee] (SASC) asked the Air Force to draw up a plan, by Sept. 30, “that leads to the production of a liquid rocket engine by 2019,” according to one of the documents, sent to Pentagon Comptroller Michael McCord by SASC Chairman Carl Levin, D-Mich.

Meanwhile, others legislators are questioning the program’s cost overruns. Though only hinted at in the article, this hold up is also related to SpaceX’s demand that the bidding for Air Force launches be opened up to competition.

Comet 67P on the day of rendezvous

8:39 am

67P/C-G on August 6

The image above was taken at a distance of 60 miles by Rosetta’s navigation camera on August 6, the day the spacecraft rendezvoused and began flying in tandem with it. It looks at the “backside” of the comet, the side where the distinction between its two components is less pronounced. Once again, no obvious craters, and the surface is pockmarked and corroded.
