SpaceX to display recovered first stage

9:04 am

The competition heats up: Rather than re-fly it, Elon Musk suggested today that, after some testing, SpaceX will likely put its first recovered Falcon 9 first stage on display instead.

“[We will] do a static fire at the launch pad there, to confirm that all systems are good and that we are able to do a full thrust hold-down firing of the rocket,” Musk said after the stage landed. The static fire will also test the modifications SpaceX has made to Pad 39A to support its rockets.

After that though, the stage will become a display piece. “I think we will keep this one on the ground for tests that prove it could fly again and then put it somewhere — just because it is quite unique,” Musk said.

Since they already have a satellite company, SES, willing to buy that first stage, this only underlines how this last Falcon 9 launch changes everything. Nor do I think this change has sunk in with most people yet. The last launch was not a one-time event. SpaceX’s intends to recover as many of its first stages as it can in all future launches. Their Falcon 9 first stage is no longer expendable. Thus, they can afford to put this first recovered stage on display because they expect all future first stages to fly again.

Proton successfully launches satellite

8:58 am

The competition heats up: A Russian Proton rocket successfully placed a commercial communications satellite in orbit today, the fifth successful launch in a row since a May launch failure and the second launch in only 10 days.

For the Russians the Proton successes during the second half of 2015 are encouraging. Whether they have solved their chronic quality control problems, however, remains unknown. I remain doubtful, especially because they have eliminated competition within their industry and folded everything into a single government entity that runs it all.

A new lightweight and very strong metal

9:03 am

Engineers have developed a new superlight and very strong metal.

A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices.

Russia hints at Vostochny schedule

8:36 am

The competition heats up? Russian sources today suggested that the first unmanned launch from Vostochny will occur on April 25, 2016 (subject to testing) while the first manned flight will occur in 2023

The second story is more significant, as it demonstrates the slow, laborious pace of this government operation. Based on the pace being set by the private companies in the U.S., by 2023 they will be flying regular manned missions from several privately run launch sites, all built quickly with as little cost as possible, with some flights possibly going beyond Earth orbit. Vostochny is expected to cost about $2.9 billion and take more than a decade to complete. The first manned missions will go to ISS only, with the first lunar manned mission not expected until after 2025 (this link also gives some details about the Russian government’s ongoing struggle to establish a 10 year plan for its space program amid continuing and changing budget crises).

The differences here are striking. While the Russian government builds an expensive spaceport built on old technology, Americans will be launching innovative and low-cost rockets that no one has ever seen before. Who do you want to hitch your ride to?

U.S. production of plutonium-238 resumes

7:10 pm

After a 30 year hiatus, the Department of Energy has produced the first plutonium-238 in the United States since the late 1980s.

Plutonium-238 is the fuel of choice for deep-space exploration. But for nearly 30 years, nobody in the United States was making it.

On Tuesday, that all changed. The Department of Energy announced that 50 grams of the stuff had been made by researchers at the Oak Ridge National Laboratory in Oak Ridge, Tenn. Fifty grams isn’t much, but this is the first time the substance has been made in the country since the Savannah River Plant in South Carolina stopped making it in the late 1980s.

What this does is provide NASA and the U.S. the ability to fly unmanned deep space missions for many more years. Without this plutonium-238, there would be no practical way to power spacecraft traveling out beyond Mars orbit.

And why did the U.S. stop making plutonium-238 in the late 1980s? The story is of course complicated, but one of the big factors is that at that time nuclear power had become politically incorrect after the Three Mile Island and Chernobyl nuclear power plant failures, and thus politicians fell over themselves to be the first to ban any such production, even if it was harmless and incredibly beneficial.

ULA buys 20 more Russian engines for Atlas 5

6:54 pm

With the Congressional ban on buying Russian rocket engines lifted, ULA today wasted no time and immediately purchased 20 more engines from its Russian supplier to use in its Atlas 5 rocket.

I could also title this post “The Death of the Vulcan Rocket”. With at least 20 engines available, ULA no longer has any need to develop that new rocket. The Air Force is still willing to overpay for Atlas 5 launches, and they will now have enough engines to fly that rocket for probably 5 to 10 more years. Since there have already been indications that the bean-counters at ULA have been reluctant to fund Vulcan’s development, I expect them to now kill it.

This of course will be a very short-sighted decision. They might get some business with the Altas 5 and the Delta from the government for those few years, but this will not make them competitive in the new rocket industry. Eventually, they are going to go the way of the American steel industry, which failed to innovate and compete with foreign companies, and in the end lost its business to those foreign companies.

In the case of aerospace, however, the competition is coming from American companies. And that is wholly to the good.

Musk vs Bezos vs Branson

6:40 pm

The competition heats up: Two stories today highlight the entertaining and totally beneficial space race that now exists between private American space companies, instigated by SpaceX’s successful vertical landing of its Falcon 9 first stage.

The first is a Popular Mechanics post showing two graphics comparing the flights of Blue Origin’s New Shepard rocket with Falcon 9’s first stage.

As they correctly note,

Both companies did a big thing and deserve accolades for it. The race is on to bring on true reusability, which has the potential to drive down the cost of space launches if done correctly. But Jeff Bezos is working with a rocket barely the size of the engine of the Falcon 9 first stage. For suborbital flight, Bezos did a big thing. For orbital flight, SpaceX did an even bigger thing. In suborbital flight, Bezos may have beat SpaceX’s Grasshopper rocket to a full suborbital flight and return, but he isn’t ready to fly with the Falcon yet.

Blue Origin is posed to become SpaceX’s biggest competitor, but they clearly are behind in the race and will need to do a lot to catch up.

The second article is an excellent essay by Doug Messier at Parabolic Arc noting that at this stage the race isn’t really between Musk and Bezos but between Bezos and Richard Branson.

Messier notes that Bezos’ New Shepard rocket is built to sell tickets to tourists on suborbital flights. He is not competing with SpaceX’s orbital business but with Richard Branson’s space tourism business at Virgin Galactic. And more significantly, it appears that despite a ten year head start, Richard Branson appears to be losing that race, and badly.

Not only that, but while SpaceShipTwo is essentially a deadend, capable only of suborbital tourism, Bezos’s New Shepard was designed to be upgraded to an orbital ship and rocket. Once they chaulk up some suborbital ticket sales and some actual flights, something they seem posed to do in the next two years, they will likely then begin moving into the orbital field. They will then leave Virgin Galactic far behind.

InSight Mars mission suspended

3:14 pm

Because of a serious technical problem with its prime instrument, NASA has decided that its InSight Mars lander will not make its March 2016 launch window and has suspended the mission.

NASA said the decision to delay follows unsuccessful attempts to repair a leak affecting the device, which requires a vacuum seal around its three main sensors to withstand the harsh conditions of the Martian environment. A leak discovered earlier this year, that prevented it from retaining vacuum conditions, was successfully repaired, and the mission team “was hopeful the most recent fix also would be successful.”

However, the instrument once again failed to hold a vacuum during testing on Monday in extreme cold temperature.

It is even possible that the mission will be cancelled entirely because of the problem.

Images of Ceres from Dawn’s lowest orbit

10:40 am

The Dawn science team has now released new high resolution images of Ceres taken from the spacecraft’s lowest orbit.

Dawn took these images of the southern hemisphere of Ceres on Dec. 10, at an approximate altitude of 240 miles (385 kilometers), which is its lowest-ever orbital altitude. Dawn will remain at this altitude for the rest of its mission, and indefinitely afterward. The resolution of the new images is about 120 feet (35 meters) per pixel.

Among the striking views is a chain of craters called Gerber Catena, located just west of the large crater Urvara. Troughs are common on larger planetary bodies, caused by contraction, impact stresses and the loading of the crust by large mountains — Olympus Mons on Mars is one example. The fracturing found all across Ceres’ surface indicates that similar processes may have occurred there, despite its smaller size (the average diameter of Ceres is 584 miles, or 940 kilometers). Many of the troughs and grooves on Ceres were likely formed as a result of impacts, but some appear to be tectonic, reflecting internal stresses that broke the crust.

Make sure to click on the link. The images show that Ceres is not the dull boring surface that the wider shots have suggested.

The coming bright age

10:20 am

As regular readers of Behind The Black know, I routinely report on the depressing state of western culture, where our intellectual academic community appears more interested in standing with their eyes closed and their fingers in their ears yelling, “La-la-la-la-la-la-la-la!!!” as loud as they can so they can avoid learning new things or hearing facts that might disturb their tiny little bubble of incorrect assumptions. Such behavior is comparable to the close-minded thinking that caused the medieval dark ages, when the search for knowledge died and Roman culture withered. It took a thousand-plus years for western civilization to come out of that shadow and begin to grow again.

The success of SpaceX yesterday to vertically land the first stage of its Falcon 9 rocket while also successfully putting eleven smallsat satellites in orbit however that gives me hope that a dark age is not coming. Despite living in a time when freedom is denigrated, when free speech is squelched, and when oppressive regulation and government control is the answer to every problem, the enduring spirit of the human soul still pushed through to do an amazing thing.

SpaceX’s success is only the beginning. The ability to reuse the engines and first stage will allow them to lower their launch costs significantly, meaning that access to space will now be possible for hundreds if not thousands of new entrepeneurs who previously had ideas about developing the resources of the solar system but could not achieve them because the launch costs were too high. In fact, the launch of Orbcomm’s smallsat constellation by this Falcon 9 demonstrated this. Not only is this company proving the efficiency of smallsats, they now have a launch vehicle, the Falcon 9, that they can afford to use. In the past Orbcomm would have been hard-pressed to finance its satellite constellation using the expensive rockets of older less innovative launch companies like Boeing and Lockheed Martin.

SpaceX however is not alone in revolutioning the launch industry. Blue Origin has also demonstrated some of the same launch capabilities as SpaceX, vertically landing its first stage. In competition these two companies and their armies of brilliant and creative engineers are going to make it possible for the human race to explore and colonize the solar system.

Even as old Earth sinks into increasing regulation, oppressive rule-making, and tyrannical close-mindedness, the explorers of the solar system, led by this new American launch industry, will break away from that morass. Hopefully, the new space-faring societies they create out there amid the stars will, like the settlers of North America in the 1600s, help re-establish freedom for future generations back here on Earth.

SpaceX lands the first stage!

6:42 pm

The competition heats up: SpaceX has successfully vertically landed its first stage after putting 11 Orbcomm satellites into orbit.

If you go to the SpaceX website they broadcast the whole thing live. And people are going crazy there right now.

I am sure they will post the video at the SpaceX website and youtube channel later today. The link to the full broadcast of the launch and landing is here. The landing sequence begins at about 25 minutes in, a little less than four minutes after launch.

Cause of Soyuz docking problems pinpointed

8:48 am

The failure of a Soyuz capsule to dock automatically with ISS last week is now attributed to a software problem that failed to provide the right commands to the spacecraft’s thrusters.

The problem has now been linked by the Russian press to three different causes. I wonder if they actually have any idea at all, or are simply throwing out red herrings in order to distract everyone from noticing the problem at all.

Budget bill lifts ban of Russian engines on Atlas 5

11:53 pm

The giant omnibus budget bill negotiated and announced by Congress today includes language that effectively lifts the limit on the number of Russian engines that ULA can use in its Atlas 5 rocket.

John McCain (R-Arizona) is very unhappy about this, and is threatening to ban the use of any Russian engines on any further Atlas 5 in future bills.

On the record, I make this promise. If this language undermining the National Defense Authorization Act is not removed from the Omnibus, I assure my colleagues that this issue will not go unaddressed in the Fiscal Year 2017 National Defense Authorization Act. Up to this point, we have sought to manage this issue on an annual basis, and we have always maintained that, if a genuine crisis emerged, we would not compromise our national security interests in space. We have sought to be flexible and open to new information, but if this is how our efforts are repaid, then perhaps we need to look at a complete and indefinite restriction on Putin’s rocket engines.

Whether McCain will be able to do this however is somewhat questionable. He is up for election next year, is very disliked in Arizona, and is likely going to face a very tough primary battle that he very well might lose. Even so, it really won’t do ULA much good if they get the right to keep using Russian engines. As I said earlier today, ULA’s future as a rocket company is extremely limited if it doesn’t develop a cheaper rocket. Continued use of the Atlas 5 and these Russian engines does nothing to get that cheaper rocket built.

Russian officials decide to broadcast launches

10:12 am

The return of the Soviet Union! After experimenting with the online broadcast yesterday of the Soyuz manned launch, Russian officials announced today that they will continue these broadcasts on future launches.

The launch from Baikonur was for the first time broadcast via the Luch (Ray) satellite retransmission system. More than 1,000 people have watched the live broadcast.

The Luch system is designed to solve the problems of relaying information of monitoring and control of low-orbit spacecraft, manned space systems, including the Russian segment of the International Space Station, and to serve in controlling launch vehicle flights using an alternative technology. The Luch is a series of geosynchronous Russian relay satellites, used to transmit live TV images, communications and other telemetry from the Soviet/Russian space station Mir, the Russian Orbital Segment of the International Space Station and other orbital spacecraft to the Earth, in a manner similar to that of the US Tracking and Data Relay Satellite System. “One of the main spheres we intend to develop is our functions of mobile communications and data retransmission, including for the broadcast of launches as the most interesting events for the promotion of space exploration,” Komarov said. According to the Roscosmos chief, the Gonets company will be engaged in the development of this sphere. [emphasis mine]

Wow! A thousand people watched the launch! Isn’t that amazing!

In other words, either they didn’t make it easy for the public to find the broadcast online, or they didn’t make it public at all and the 1,000 viewers were merely government apparatchiks. It is clear from the article that they are still working to get their communication satellite network back into operation — which crumbled in the 1980s and 1990s with the collapse of the Soviet Union — but if they can broadcast to 1000 people they can broadcast to far more than that. Hopefully after this first effort they will broaden its access for future launches, though I wonder if that will happen. All of Russian aerospace is now government-controlled, and the natural inclination of government bureaucrats is to squelch information so that people don’t see bad things happen.

Soyuz docking issue during ISS arrival

9:37 am

When the manned Soyuz rendezvoused and docked with ISS yesterday, there was a problem with the automatic docking system, requiring the astronauts to take over and manually dock the spacecraft.

Initial reports suggested the failure was with the radar system having a conflict with the communications systems on the berthed Cygnus capsule. The link above instead claims the failure was caused by a malfunction in one of the Soyuz attitude thrusters. The former would be annoying but less of a concern than the latter. A thruster malfunction is somewhat rare, and would be another indication of the serious quality control problems in the Russian aerospace industry.

New China manned vehicle under development

7:42 pm

The competition heats up: China has begun development of two versions of a second generation manned capsule.

Instead of the three-module arrangement of the current Shenzhou vehicle, the future Chinese crew vehicle will adopt a two-module arrangement, with a large inhabitable crew module at the front, and an uninhabitable cylindrical-shaped service module at back. The size of the re-entry vehicle will be twice of Shenzhou’s, capable of accommodating up to six crew members. A docking port and its associated docking sensors are fitted to the front-end of the crew module. The spacecraft can be fitted with two different service modules, with different propulsion systems and propellant capacities.

In other words, rather than copy and upgrade the design of the Russian Soyuz, as they did with their Shenzhou capsule, they will copy and upgrade the American Apollo capsule.

ULA’s fight to use Russian engines continues

9:06 am

This article provides a detailed account of the political battle between ULA and Congress of its future use of Russian engines in its Atlas 5 rocket.

Congress has imposed a strict limit on the number of engines the company can use. ULA is still lobbying for an increase, claiming that the limit will mean that they will not be able to meet the government military launch needs for a few years when the engines on hand run out and its new American-built engines are not yet available.

In the long run I think this battle is irrelevant. What really matters is what it costs to launch a satellite, and ULA is simply not focused on reducing its costs. Consider this quote from the article, emphasis mine:

ULA has designed a new rocket dubbed Vulcan that features a U.S.-made engine, but this vehicle will not be available until around 2021, assuming the project gets funded — which is by no means a given.

They made a big deal earlier this year about how Vulcan will soon replace Atlas 5 at a lower cost, but it now appears that this was merely a public relations event. ULA wants someone else to pay for this new rocket, and thus has not yet committed any of its own money to begin actual development.

Other companies however are funding the development of their own new American-made rockets that will also be far cheaper to fly. Sooner rather than later our spendthrift Congress is going to mandate that the military use those cheaper rockets. If ULA doesn’t get moving it will be left in the dust, whether or not Congress allows it to use more Russian engines.

New astronaut crew to ISS, including Brit

8:47 am

A Russian Soyuz rocket today successfully launched a new crew to ISS, including Great Britain’s first official astronaut.

Tim Peake is not the first Brit in space, but he is the first paid for by the British government. The first British citizen to fly in space, back in 1991, was Helen Sharman, whose flight was a publicity stunt mostly paid for by the Russians themselves.

The crew is expected to dock with ISS later today.

Rosetta hi-res images released

8:41 am

Lots of cool images! The science team running Rosetta’s high resolution camera have finally made available to the public the camera’s large archive of images.

The images cover the period 20 June 2014 – 16 September 2014, corresponding to Rosetta’s approach to the comet, arrival, and insertion into orbit.

In exchange for creating and running the mission, the scientists had been given a 12 month period in which these hi-res images belonged entirely to them. This gave them the chance to use them to publish papers documenting their discoveries. While this is a reasonable arrangement — used by most planetary missions in some manner to reward the scientists who made the mission possible — with Rosetta the hi-res images were kept so close to the vest that practically none have been seen, until now. Moreover, this release is very late, anywhere from 15 to 18 months after the images were taken, not 12.

Most other planetary missions make sure that at least some images are released as the mission proceeds, since the images were paid for by the public. The European Space Agency should take a look at its future policies for publicly-funded missions to make sure the public gets better access in the future.

Proton launch success

8:22 am

The competition heats up: Russia’s Proton rocket successfully launched a military communications satellite on Sunday.

The link provides a lot of interesting information about the satellite as well as some recent upgrades the Russians have installed in Proton, but for context the last two paragraphs are probably the most important:

Sunday’s launch was the seventy ninth orbital launch attempt of 2015 and the seventh Proton launch of the year. Five of the six previous launches were successful, with May’s launch of Mexsat-1 failing to achieve orbit. Proton has had eleven failures in the last ten years, with 2009 the only year since 2005 in which it has not suffered at least one anomaly.

The next Proton launch is scheduled for 23 December, with another Proton-M/Briz-M carrying the Ekspress-AMU1 communications satellite. Details of any future Garpun launches are not available.

The launch reliability for Proton has seriously fallen since 2005, and to compete in the changing launch market they will need to fix this.

Second Google Lunar X-Prize launch contract confirmed

10:05 am

The competition heats up: The Google Lunar X-Prize has now confirmed two launch contracts for sending a privately financed and built rover to the Moon by 2017.

Moon Express is now the second company to have a launch contract for their lunar lander spacecraft verified by the X Prize Foundation. An Israeli team, SpaceIL, had its contract to launch a lander on a SpaceX Falcon 9 verified by the foundation in October. SpaceIL will be one of the primary payloads on a launch purchased in September by Spaceflight Industries that will carry about 20 other spacecraft. That initial launch contract verification allowed the foundation to formally extend the competition’s deadline to the end of 2017. Teams have until the end of 2016 to submit their own launch contracts in order to continue in the competition.

Sixteen teams remain in the competition, announced in September 2007, to land a privately-developed spacecraft on the moon, travel at least 500 meters across its surface, and return high-resolution videos and other data. Some teams are cooperating with others for launch arrangements.
