A list of all smallsat launch rockets

8:29 am

Doug Messier has compiled a very interesting table showing all the known smallsat launch vehicles presently under construction or in operation.

Most of the operational rockets, such as Orbital ATK’s Minotaur, have turned out to be too expensive for their small payloads, and have not been very profitable. The new generation of rockets, however, have the chance of success, as they are all working to reduce the cost significantly. Keep your eye especially on Rocket Labs (which just signed a contract with Moon Express), Swiss Space Systems, Firefly Space Systems, and (dare I say it?) Virgin Galactic.

France considers developing reusable first stage

12:57 pm

The competition heats up: Two French government aerospace agencies have announced that they are researching the development of a reusable first stage.

It is very unclear how this research will be applied, since Europe’s replacement for the Ariane 5 is being built by Airbus Safran and they have made it clear that they only intend to recover their rocket’s engines, not the entire first stage.

ULA completes its 100th successful launch

12:52 pm

The competition heats up: In a rare private commercial launch, ULA’s Atlas 5 rocket put a Mexican communications satellite in orbit on Friday, the 100th successful launch for the company.

The company still faces the same problems it did before this launch: It is running out of Russian engines for the Atlas 5, Congress is not willing to give them permission to use more, and the cost competition from SpaceX is not going to let up.

Moon Express buys launch contract

12:17 pm

The competition heats up: The leading private effort to win the Google Lunar X-Prize, Moon Express, has signed a contract with the smallsat launch company Rocket Labs for three launches.

Mountain View, California-based Moon Express plans to use the launches to send to the moon new, smaller versions of its MX-1 lunar lander. Two of the launches will take place in 2017, with a third to be scheduled. All three will use Rocket Lab’s Electron small launch vehicle, whose first flight is scheduled for no earlier than late 2015 from New Zealand. – See more at: http://spacenews.com/moon-express-buys-rocket-lab-launches-for-lunar-missions/#sthash.J1hEuCp3.dpuf

Rather than piggyback on the major launch of big payload, which would deny them any control over launch dates, they have signed with a new and as yet unproved small rocket company. The result? Not only do we have the chance of getting our first privately built lander on the Moon, the contract jumpstarts a new rocket company designed to put small payloads into space.

Charon in color

11:39 am

Charon

The New Horizons science team has released new high resolution images of Pluto’s moon Charon, including the global enhanced color view on the right.

High-resolution images of the Pluto-facing hemisphere of Charon, taken by New Horizons as the spacecraft sped through the Pluto system on July 14, and transmitted to Earth on Sept. 21, reveal details of a belt of fractures and canyons just north of the moon’s equator. This great canyon system stretches across the entire face of Charon, more than a thousand miles, and probably around onto Charon’s far side. Four times as long as the Grand Canyon, and twice as deep in places, these faults and canyons indicate a titanic geological upheaval in Charon’s past. “It looks like the entire crust of Charon has been split open,” said John Spencer, deputy lead for GGI at the Southwest Research Institute in Boulder, Colorado. “In respect to its size relative to Charon, this feature is much like the vast Valles Marineris canyon system on Mars.”

The team has also discovered that the plains south of the canyon, informally referred to as Vulcan Planum, have fewer large craters than the regions to the north, indicating that they are noticeably younger. The smoothness of the plains, as well as their grooves and faint ridges, are clear signs of wide-scale resurfacing.

In many ways these images remind me of an upside-down Mars, with the smooth lower plains in the south instead of the north. Obviously, the causes on Charon are going to be significantly different than those on Mars.

Vostochny launch building built to the wrong size

8:37 am

Government marches on! The Russians have just discovered that their Soyuz 2 rocket does not fit in the building just finished at their new spaceport at Vostochny.

The cutting-edge facility was meant be ready for launches of Soyuz-2 rockets in December, but an unidentified space agency of a of a told the TASS news agency of a of a late Thursday that the rocket would not fit inside the assembly building where its parts are stacked and tested before launch. The building “has been designed for a different modification of the Soyuz rocket,” the source said, according to news website Medusa, which picked up the story from TASS.

The rocket had just been delivered to Vostochny for assembly, so this report, though unconfirmed at this time, fits well with current events.

NASA pulls funding from private asteroid hunter

10:57 pm

Because of a failure to meet its developmental deadlines, NASA has cut its ties with the privately funded Sentinel satellite, designed to spot 90% of all near Earth asteroids that might pose a threat to the Earth.

The problem for the B612 Foundation, the private company committed to building Sentinel, is that they haven’t clearly laid out a way any investors could make money from the satellite. Thus, they have so far raised only $1.6 million from private sources. They need almost half a billion to build it, according to their own budget numbers.

Congress places additional limits on Russian rocket engine use

10:48 pm

Bad news for ULA and the Atlas 5: A defense bill approved by the Congressional negotiators has placed further limits on the number of Russian rocket engines ULA can use in future Atlas 5 government launches.

The bill, which still faces an Obama veto, only allows ULA to use 9 more Russian engines. The company however says it needs to have at least 18 available to keep its ability to launch government payloads while it develops its new Vulcan rocket.

Read the whole article. The political complexity of this whole situation does not bode well for ULA or its Vulcan rocket. Too many players with too many conflicting goals appear to make it difficult for the company to push the development forward efficiently.

Smallsat company buys its own Falcon 9 rocket to launch 20 satelites

10:40 pm

The competition heats up: Spaceflight Industries has purchased a single dedicated Falcon 9 rocket launch to launch 20 small satellites sometime in 2017.

Buying a dedicated launch, rather that seeking excess capacity on other launches, provides Spaceflight with more than just additional payload capacity. Secondary or “rideshare” payloads are subject to the schedule of the primary capability, and can be bumped off the launch if the mass of the primary payload grows. With a dedicated mission, Spaceflight is in greater control. “It helps us establish a regular cadence of launches,” Blake said. “We can book all kinds of rideshare passengers onto something that is going to be there at a certain time to a certain orbit.”

This purchase also indicates the growing strength of the smallsat industry. These companies are beginning to gain the investment capital to buy their own launches rather than fly as secondary payloads.

Development of Blue Origin’s BE-4 rocket engine moves forward

10:33 pm

The competition heats up: Blue Origin has completed more than 100 development tests of its new BE-4 rocket engine, being developed for ULA.

Much of this announcement sounds like public relations blather. However, it contained this nugget of information that is crucial to understanding why this engine is likely to get built quickly:

The BE-4 engine is also the leading candidate to be used in the first stage of ULA’s Vulcan vehicle. Speaking to reporters after the Sept. 15 Florida event, Blue Origin founder Jeff Bezos said that while he was aware of competing engines for the Vulcan, like the AR-1 under development by Aerojet Rocketdyne, he was focused on completing the BE-4. “We’re going to build the best 21st century engine that we can for ULA,” he said. “Ultimately they will make the decision about what they want to do.”

Bezos also noted that, unlike the AR-1 or other concepts, Blue Origin was not seeking funding from the U.S. Air Force to help pay for development of the BE-4. “The most unique feature of the BE-4 engine is that it’s fully funded,” he said. “It’s not something you see in rocket engine programs very often.” [emphasis mine]

Aerojet Rocketdyne wants the government to pay for its new AR-1 engine. To get that done, they need to lobby Congress for funds that are simply unreliable in these days of budget-cutting. Moreover, it means that Aerojet Rocketdyne is not fully committed to the engine: if the funds don’t arrive they won’t build it.

Blue Origin is going forward, fully committed, and will likely deliver, if only because they can’t get their investment back until they do.

Creeping towards commercial and private weather satellites

10:13 pm

Link here. The editorial at Space News outlines the effort in Congress to force NOAA to buy weather data supplied by private commercial satellite companies rather than build its own satellites. It also outlines what might be the major reason private companies have never been able to make a profit in the field:

The agency [NOAA] is obliged as a member the World Meteorological Organization [WMO] to share weather data openly and freely with other nations. If that obligation applies to commercially procured data, as NOAA insists, it could dramatically shrink the addressable global market for commercial weather data — to the point that it could shatter business models. – See more at: http://spacenews.com/editorial-inching-toward-a-commercial-weather-policy/#sthash.vG9fs3Sj.dpuf

In other words, private companies can’t sell their data because of the U.S.’s membership in the WMO, which requires that data to be made available for free. To make the commercialization of weather work, the U.S. is going to have to pull out of WMO, something I think will be difficult to sell to Congress.

Virgin Galactic tests new rocket engine

10:04 pm

The competition heats up? Virgin Galactic has released video of a test burn of a new engine designed to work with its LauncherOne rocket.

I put a question mark above because I have become very skeptical of any press announcements out of Virgin Galactic. They might have made progress on this new engine, and it also appears that they are doing engine work first for developing LauncherOne, a wise plan. However, their track record with SpaceShipTwo makes me doubtful about their ability to follow through. They need to produce to make me a believer once again.

Comet 67P/C-G was formed by a soft collision

9:04 am

Scientists, using data from Rosetta, have concluded that Comet 67P/C-G’s double lobed shape was caused by the slow-motion collision of two distinct comets.

By using high-resolution images taken between 6 August 2014 and 17 March 2015 to study the layers of material seen all over the nucleus, they have shown that the shape arose from a low-speed collision between two fully fledged, separately formed comets. “It is clear from the images that both lobes have an outer envelope of material organised in distinct layers, and we think these extend for several hundred metres below the surface,” says Matteo Massironi, lead author from the University of Padova, Italy, and an associate scientist of the OSIRIS team. “You can imagine the layering a bit like an onion, except in this case we are considering two separate onions of differing size that have grown independently before fusing together.”

While erosion continues to eat away at the comet’s surface, changing its shape, the two lobes formed separately, though in much the same way.

Boeing’s first stealth plane concept

10:57 am

Boeing has just released the few remaining photos and documents relating to a 1960s stealth plane concept, including pictures of a half-scale prototype.

The concept dates back to the early 1960s, with a one-half scale model of the aircraft being built sometime between 1962 and 1963. The aircraft was an exercise in utilizing specific materials and shapes to drastically reduce the radar cross-section of a tactical aircraft. From this pioneering design, five Boeing “stealth” patents were awarded, and they only appear to have shown up in public records in the early 1990s, decades after they were officially filed. 

The model of Quiet Bird was said to have been tested at Boeing’s Wichita facility in 1962-1963, all of which occurred on a radar range. No actual flight testing of Quiet Bird itself was said to have happened, though. But the tests were highly successful: they proved that it was possible to drastically decrease the radar signature of a tactical aircraft.

Using fish to study bone loss in weightlessness

9:04 pm

A Japanese experiment on ISS, comparing the development of fish in weightlessness with those on the ground, has provided` scientists more information about bone density loss in weightlessness.

Akira Kudo at Tokyo Institute of Technology, together with scientists across Japan, have shown that medaka fish reared on the International Space Station for 56 days experienced increased osteoclast activity – bone cells involved in the re-absorption of bone tissue – likely leading to a subsequent reduction of bone density. They also found several genes that were upregulated in the fish during the space mission. The team generated fish with osteoclasts that emit a fluorescent signal. They sent 24 fish into space as juveniles, and monitored their development for 56 days under microgravity. The results were compared with a fish control group kept on Earth.

Kudo and his team found that bone mineral density in the pharyngeal bone (the jaw bone at the back of the throat) and the teeth of the fish reduced significantly, with decreased calcification by day 56 compared with the control group. This thinning of bone was accompanied by an increase in the volume and activity of osteoclasts. The team conducted whole transcriptome analysis of the fish jaws, and uncovered two strongly upregulated genes (fkbp5 and ddit4), together with 15 other mitochondria-related genes whose expression was also enhanced. Reduced movement under microgravity also has an influence. The fish began to exhibit unusual behavior towards the latter stages of their stay in space, showing motionless at day 47.

What the data mostly confirms is that long-term weightlessness is a bad thing for the development of bones, and not just in humans. Whether scientists can use these results to counter these harmful effects is not clear, however.

First rocket arrives at Vostochny

8:25 am

The competition heats up: The Russians have now delivered to Vostochny the first Soyuz rocket for launch from that spaceport.

The launch is still planned for December, though no one would be surprised if it got delayed.

One minor but interesting thing to note at the link above. The pictures of the train and the containers holding the rocket sections were taken by none other than Dmitry Rogozin, the Russian deputy prime minister whom Putin himself has placed in charge of the construction of Vostochny. This is as if Obama put Biden in charge of NASA’s SLS program, and Biden himself took pictures of some construction event for the news media.

Rosetta data reveals how a comet evaporates

9:57 am

Newly released Rosetta data has shown, for at least one area on the surface of Comet 67P/C-G, the process by which the surface ice is replaced by water ice from below as the comet rotates and sunlight causes the surface ice to evaporate away.

The data suggest that water ice on and a few centimetres below the surface ‘sublimates’ when illuminated by sunlight, turning it into gas that then flows away from the comet. Then, as the comet rotates and the same region falls into darkness, the surface rapidly cools again. However, the underlying layers remain warm owing to the sunlight they received in the previous hours, and, as a result, subsurface water ice keeps sublimating and finding its way to the surface through the comet’s porous interior.

But as soon as this ‘underground’ water vapour reaches the cold surface, it freezes again, blanketing that patch of comet surface with a thin layer of fresh ice. Eventually, as the Sun rises again over this part of the surface on the next comet day, the molecules in the newly formed ice layer are the first to sublimate and flow away from the comet, restarting the cycle.

They discovered this process when they noticed surface ice evaporating in this region during the comet’s 6-hour day and then getting resurfaced with ice during the comet’s 6-hour night.

Meanwhile, Rosetta is about to move as much as 1500 kilometers away from the comet for several weeks so that its scientists can study its coma more broadly.

Aerojet is considering increasing its $2 billion offer to buy ULA

9:29 am

The competition heats up: A news report today suggests that Aeroject Rocketdyne is considering increasing its $2 billion bid to buy ULA, thus forcing that company to use its rocket engines rather than Blue Origin’s.

The article contains a lot of information that helps explain the background behind Aerojet Rocketdyne’s offer as well as ULA’s recent switch to Blue Origin. For one thing, ULA apparently dumped Aeroject because the company refused to invest any of its own money in developing a new rocket engine.

Last summer, Aerojet’s board also rejected ULA’s request that Aerojet invest $300 million to accelerate work on the AR-1 engine it is developing as an alternative to the Russian RD-180 engine that powers ULA’s Atlas V rocket, the sources said. … Aerojet’s refusal to invest more in the AR-1 engine ultimately drove ULA to opt for the BE-4 engine being developed by privately held Blue Origin, which is owned by Amazon.com founder and billionaire Jeff Bezos, the sources said.

More significant, it appears that the Rocketdyne portion of the company is owned by the Russians!

An Aerojet takeover of ULA would also require Russia to give its regulatory approval and transfer a technology license for use of the RD-180 engines, according to two of the sources. Russia refused to transfer the license to Aerojet when it bought Rocketdyne from Pratt & Whitney, a United Technologies Corp (UTX.N) unit in 2013, forcing Pratt to retain control of a small company that brokers RD-180 sales, and could be more reluctant to do so now, the sources said.

While the quote above is somewhat confusing, it certainly suggests that, with Congress banning the use of Russian-built engines in American rockets, using Aerojet Rocketdyne engines by ULA has become problematic.

In related more bad news for Aeroject Rocketdyne, the company has just agreed to pay Orbital ATK $50 million in connection with last year’s Antares launch failure. In addition, they will take back the Russian-built engines they refurshed and sold to Orbital. The agreement also ends the company’s part in Antares.

China debuts another new rocket

9:10 am

The competition heats up: China successfully completed the first launch of another new rocket today, putting three technology satellites into orbit with its solid-fueled Long March 11 rocket.

The Long March-11 (Chang Zhwng-11) is a small solid-fueled quick-reaction launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT). It’s goal is to provide an easy to operate quick-reaction launch vehicle, that can remain in storage for long period and to provide a reliably launch on short notice. Very little is known about the rocket, with only one badly taken photo available on the internet. However, LM-11 is known to be a solid-fueled launch vehicle equipped with a liquid-fueled trim stage.

Moreover, the three satellites the rocket put in orbit are cubesats designed to test formation flying technologies. This puts China in the forefront of the effort to make these tiny satellites capable of doing what larger satellites now do, thus making possible the eventual replacement of those more costly larger satellites.

New Pluto images

4:07 pm

thumbnail of Pluto closeup

Cool image time! The New Horizons team has released some new images. A thumbnail of what I think is the most interesting image is shown on the right. Be sure to look at the full resolution image. It shows a flat plain of what look like frozen polygon plates with a thin layer of what appear to be dunes. In the center some rocks poke out like islands, with what looks like a wind-swept wake to the right. The wake could be caused by Pluto’s very thin atmosphere. Or maybe there are currents that slowly push the frozen plates past the harder rocks (which probably are ice, which in Pluto’s very cold environment has the structural strength of granite).

These images were posted on the New Horizons website with no accompanying press release. I think the science team has decided it will just upload them, and reserve press releases for when they have accumulated enough data to announce some intelligent conclusions. Right now, they can only speculate as wildly as I from these images. It is reasonable to give them the time to assess the data more closely before announcing any explanations. At the same time, we should also congratulate them for posting the images immediately so that others can see them.

Update: a press release was released, though it really doesn’t add much except review the images.

Boeing reveals landing sites for Starliner

11:33 pm

The competition heats up: Boeing has revealed the prime landing sites for its manned Starliner capsule.

Boeing is still finalizing a list of five candidate landing sites in the Western United States, but the U.S. Army’s White Sands Missile Range in New Mexico and the Army’s Dugway Proving Ground in Utah will initially be the prime return locations, said Chris Ferguson, deputy manager of the CST-100 Starliner program. The capsules will parachute to airbag-cushioned landings after each mission, beginning with the CST-100’s first test flights in 2017.

The article also outlines the overall status of Starliner, including what sounds to me like some scheduling and design concerns:

Boeing is taking a different approach to development of its human-rated spacecraft than SpaceX, which has already completed a pad abort test and plans an in-flight abort demo in late 2016. SpaceX is testing as it goes, while Boeing is doing more design work up front. “A lot of focus is on ensuring, at this phase, that we’ve got full rigor in all our processes and all of our designs, really trying to buy down the risk that something could come up downstream to perturbate either our design or our schedule,” Mulholland said.

Boeing plans no such in-flight escape test, and Mulholland said it can prove out the CST-100 abort system through wind tunnel analyses. “That’s our philosophy — to make sure we don’t run a test just to go run a test,” Mulholland said. “We make sure we fully understand all the requirements that we need to certify to, and we pick the best approach.”

Mulholland said the sequence of test flights in 2017 is tight, but Boeing’s schedule has margin to achieve the start of operational missions by the end of that year. Managers decided to move the pad abort test from early 2017 to August, a change that Mulholland said created more margin in the schedule leading to the first crew flight. [emphasis mine]

The lack of an in-flight test of the abort system is worrisome. This sounds just like NASA and Boeing in the shuttle era when they repeatedly made overconfident claims about the shuttle’s reliability and safety that were completely unrealistic, based not on tests but on computer simulations. The tight schedule also is a concern, especially because of the corporate culture of Boeing, which has a history of using these contracts to squeeze money from the government while putting a low priority on actually building anything.

I fear that might be what is happening here, especially since Boeing, unlike SpaceX, refused to build much of anything prior to the announcement of its Starliner contract. The company does not like to take any risks at all.

GAO criticizes the staff and budget request of FAA’s commercial space office

11:12 pm

A GAO report has concluded that the FAA has not provided sufficient justification for its 2016 requested budget and staff increases for its Office of Commercial Space Transportation (AST).

AST requested an additional $1.5 million more plus an increase of its staff by 13 to handle what it expects to be an increase in commercial launches. However,

The GAO report cautioned about using predictions of launches as a reason for hiring additional staff because, in recent years, “the actual number of launches during those years was much lower than what FAA projected.” In one example, the FAA projected it would license more than 40 launches and reentries in 2014, but the actual number was about 20.

The report also revealed a split among companies in the commercial launch business about the importance of increasing AST’s budget. While industry organizations like the Commercial Spaceflight Federation have expressed their support for the proposed budget increase, only three of the nine companies surveyed by the GAO believed the office has insufficient resources to deal with its workload. Three other companies thought the office has sufficient resources, and the remaining three expressed no opinion. The report did not identify which companies held those opinions, but did list the nine companies contacted by the GAO: Blue Origin, Boeing, Masten Space Systems, Orbital ATK, SpaceX, United Launch Alliance, Virgin Galactic, Vulcan Aerospace and XCOR Aerospace.

The second paragraph in the quote above suggests that a majority of the private companies that AST would regulate are not enthused about giving that government agency more resources or abilities. To me, I suspect that the phrase “We’re here to help you!” and what it usually signifies about the government has something to do with that lack of enthusiasm.

ULA and Orbital ATK ink new rocket motor contract

10:55 pm

The competition heats up: ULA has signed a new contract with Orbital ATK to provide solid rocket motors for its Atlas 5 and Vulcan rockets.

This deal is another nail in the coffin of Aerojet Rocketdyne, as it strongly suggests that the corporate leadership at ULA is very uninterested in doing any business with that rocket engine builder. Recently they have been taking their business every where but to Aerojet.
