The mysterious upcoming commercial launch in Alaska

Link here. The article takes a detailed look to try to find out the unnamed commercial company behind the mid-April launch, and learns that it will be a suborbital launch, and that the company might be one called Astra Space.

Alaska Aerospace signed a contract with Astra Space in 2017 to support launches of that company’s vehicle from PSCA, according to the minutes of an Alaska Aerospace board of directors meeting in August 2017.

Alaska Aerospace “has a contract with Astra to support the first four launches of their small liquid fuel commercial launch vehicle from PSCA. The first launch is planned for December 2017,” the minutes state. It added that it would be the first liquid-propellant launch from the spaceport, which previously had hosted only solid-fuel rockets. “This will be a very innovative launch.”

Minutes from a Nov. 2 meeting of the Alaska Aerospace board stated that “Astra is moving forward” with plans, holding weekly planning teleconferences and paying a $100,000 deposit for a launch date. That launch was planned at that time for “possibly February or later.”

It appears the company is doing work for both NASA and DARPA, the latter of which might explain the secrecy. Or maybe the company is taking the Blue Origin approach, keeping things close to the vest until they are sure of success.

Chinese competition in smallsat rocket industry forcing prices down

Capitalism in space: The price to launch smallsats is plummeting, partly because of competitive pressure coming from China.

During a panel discussion at the Satellite 2018 conference here March 12, executives of several launch providers said they expected small launchers under development or entering service in China, either by state-owned enterprises or private ventures, to sharply reduce launch prices in the coming years. “I think the Chinese are going to drive an order of magnitude reduction in launch costs, building satellites and operating satellites. That will happen in the next five years,” said Rich Pournelle, vice president of business development for NanoRacks, a company that offers rideshare launch services for smallsats, primarily from the International Space Station.

Pournelle said that there are already signs of price pressure on launches. “Cubesats that used to cost $350,000–400,000 to launch are now $250,000 and going down,” he said. “You’re seeing a tremendous pressure from Asia, especially, on the launch side.”

Others on the panel agreed. “I think prices will settle and start to go lower as the Chinese put more launchers on,” said Curt Blake, president of Spaceflight, which also provides rideshare launch services on a variety of vehicles. “That will put pressure on U.S. launch vehicles.”

The industry concern here is that the Chinese companies are not really private, and can be heavily subsidized by China so that they can offer lower prices than anyone else. They are therefore suggesting that the government should step in and act to protect them from this competition.

I say, the government should stay out. For one thing, U.S. law today prevents American companies from using Chinese launchers, and a vast majority of the launch business is going to come from the U.S. The U.S. smallsat launch industry will have plenty of work, and can very effectively deal with the Chinese competition without government help. Moreover, this Chinese competition will only serve to enliven the market, and bring about more innovation and lower prices. The last thing we need is the government stepping in to interfere with that healthy and free competition.

Alaskan spaceport schedules first commercial launch

The spaceport in Kodiak, Alaska, has announced that its first commercial launch is now scheduled for mid-April.

The Coast Guard has notified mariners of the launch, which is scheduled for some time between April 6-13, the Kodiak Daily Mirror reported Monday.

Alaska Aerospace has launched 19 rockets in collaboration with government agencies including NASA, the U.S. Air Force and the Missile Defense Agency since the spaceport opened in 1998. But in recent years, the publicly owned corporation has partnered with commercial launch companies amid the growth of the private spaceflight industry. In preparation for the launch, berms are in place to protect the launch pad and surrounding facilities. A glass structure has been placed on top of a shipping container, which will serve as a mission control center.

Sources with knowledge of the industry have refused to name the company that will launch in April due to a non-disclosure agreement, the Daily Mirror reported. But the launch will not be from Vector Space Systems or Rocket Lab — two companies that have known contracts with Alaska Aerospace.

If not Rocket Lab or Vector, this suggests another smallsat company, such as Interorbital, Firefly, or Arca, or even a company I have not spotted up to now. If so, this will certainly heat up the competition in the smallsat rocket industry.

Port of Los Angeles approves SpaceX portside construction site

The Port of Los Angeles has granted SpaceX approval to begin construction of a booster construction and refurbishment facility on a large abandoned lot with direct ocean berthing access.

A request summary completed on March 6 details SpaceX’s proposal, laying out a bright future of rocket manufacturing for the abandoned 18-acre lot at Berth 240, one that might soon support “composite curing, cleaning, painting, and assembly [of commercial transportation vessels]” that “would need to be transported by water due to their size.

The article then speculates that this facility will be used to build SpaceX’s BFR. Maybe so, but my guess is that the facility is needed now for bringing reused Falcon 9 and Falcon Heavy boosters back after launch and prepping them for reuse.

While it is likely to take a fair amount of time to prepare the lot for the construction of a facility capable of manufacturing advanced composite rocket components, the wording in the Port documentation also suggests that SpaceX means to transfer its Falcon 9 recovery work to the new berth as soon as it’s available. Indeed, the comparatively massive space would give SpaceX far more room for recovery operations with the drone ship Just Read The Instructions (JRTI), and could potentially become a one-stop-shop for booster recovery and refurbishment. As of now, boosters recovered on the West Coast are transported to the Hawthorne factory for all refurbishment work, operations that themselves already require brief road stoppages to accommodate the sheer size of Falcon 9.

World’s largest jet engine makes first test flight

The world’s largest jet engine, built by GE Aviation for Boeing’s next generation wide body passenger jet, made its first test flight last week.

The GE9X is a monster compared to its predecessors. Due to the extensive use of composites in building the fan blades and the fan case, 3D-printed nozzles, new light- and heat-resistant ceramics, and reducing the number of fan blades from 22 to 16, GE was able to lighten the engine and expand its size so that its fan is now 134-inches (341 cm) across and the entire engine is as wide as a Boeing 737 fuselage. In addition, it can push 100,000 lb of thrust and is 10 percent more efficient than the GE90 engine used on the current generation of 777s.

The engine was attached to a 747 test plane for the flight, and the images at the link truly illustrate how large this engine is. The 747 still had its two outer normal engines attached, and the size difference is gob-smacking. When I first looked at the pictures I was convinced it was fake and that they had photoshopped this giant engine onto the 747. They didn’t.

Firefly Aerospace shows off its Lightning-1 rocket engine

Capitalism in space: Firefly Aerospace earlier this week did a demonstration static fire test of its Lightning-1 rocket engine, designed as the upper stage engine for its Alpha rocket.

Currently under development, the engine will power the upper stage of the company’s 95-foot-tall (29-meter-tall), two-stage Firefly Alpha rocket. The full vehicle will be capable of sending some 2,200 pounds (1000 kilograms) into low-Earth orbit (LEO) for about $10 million. Additionally, it will be able to send 1,300 pounds (600 kilograms) into a 310-mile (500-kilometer) Sun-synchronous orbit.

These numbers suggest to me that this rocket will be comparable to India’s PSLV. At $10 million per launch, it will beat everyone else in that rocket class. They expect to do their first test orbital launch sometime in late 2019.

Firefly Aerospace had gone bankrupt because of a successful lawsuit against it by Virgin Galactic. It then found new backers and came back from the dead.

New spaceport bill becomes law in the United Kingdom

The new colonial movement: A new bill designed to encourage the establishment of private or public spaceports in the United Kingdom has now become law.

If you wish to read the entire law, you can download it here [pdf] My quick review suggests it deals only with the regulations and liability issues necessary to encourage the creation of spaceports, which is confirmed by the language in the press release above.

In other words, the UK punted. Initially there were suggestions this law would try to deal with the property right issues related to the Outer Space Treaty. I suspect that as they reviewed those issues, the government realized they couldn’t do much about them, without changing the treaty itself, and decided to focus on what they could change. This law is aimed at bringing spaceport business to the United Kingdom, and in that I hope it works.

Russia gets multiple launch contracts for its Proton?

International Launch Services, Russia’s division for obtaining commercial launch contracts, announced yesterday that it obtained “multiple orders” for its Proton rocket.

ILS, a leading provider of commercial launch services, announced multiple launch assignments for Proton Medium launches that will include the use of both the 4.35 meter and the new 5.2 meter payload fairing. The missions will take place beginning in late 2019 from Pad 24 at the Baikonur Cosmodrome in Kazakhstan.

The reason I put a question mark in the headline is that this announcement is incredibly vague. It doesn’t name the customers. It doesn’t specify the actual number of launches. It really doesn’t tell us anything, other than the Proton has obtained launch orders!

I suspect the Russians have gotten some launch contracts, but I also suspect that these contracts are with Russian companies only, and they want to hide this fact because it indicates once again that they have lost their international market business to SpaceX and others. Launch orders from within Russia are essentially ordered to go to Proton by the government. No one else however wants to buy their services, because no one has faith in their quality control processes. There have been too many launch failures in recent years.

New Air Force launch contracts for SpaceX and ULA

Capitalism in space: The Air Force announced yesterday that it has awarded launch contracts to ULA and SpaceX worth nearly $650 million.

Colorado-based ULA was awarded a $355 million contract for its launch services to deliver two Air Force Space Command spacecraft, labeled AFSPC-8 and AFSPC-12, to orbit. The missions are expected to launch from Cape Canaveral Air Force Station by June 2020 and March 2020, respectively.

…SpaceX, meanwhile, secured a $290 million contract to launch three next-generation Global Positioning System satellites for the Air Force, known as GPS III. The first is expected to launch from the Space Coast by March 2020, either from Cape Canaveral Air Force Station’s Launch Complex 40 or Kennedy Space Center’s pad 39A.

Note the price difference between the ULA and SpaceX.launches. ULA’s cost is $177.5 million per launch, while SpaceX’s is $96.7 million per launch. While it could be that the ULA launches need to cost more because of the nature of the payloads, I don’t buy it. The company simply charges too much, partly because its rockets are expensive. The Air Force however has a strategic need to have more than one launch company, so they bite their tongues and pay the larger amount.

I should add one positive aspect about ULA’s price. The price is considerably below what they used to charge, before SpaceX entered the game. Then, their lowest launch price was never less than $200 million, and usually much more. This lower price indicates they are working at getting competitive. Though SpaceX offers the Falcon Heavy at $90 million (with reused boosters) and $150 million (all new) to commercial customers, its price for the Air Force will likely be higher because of the Air Force’s stricter requirements. This means that ULA’s per launch price of $177.5 here is getting quite close to being competitive with the Falcon Heavy.

Note that the article mentions that SpaceX has also gotten two more commercial launch contracts with DigitalGlobe, so that company’s business continues to boom.

Bezos releases video of BE-4 static fire test

Capitalism in space: Jeff Bezos today released a video of a 114 second engine test of Blue Origin’s BE-4 engine.

I have embedded the video below the fold. The test was at 65% power, but it strongly suggests that the company is getting close to certifying this engine for use, which will then allow ULA to make its final decision on whether to use it in its Vulcan rocket. It also will allow Blue Origin to begin construction of its own New Glenn rocket, which is set to begin flights in 2020.

Orbital ATK unveils new satellite servicing robots

Capitalism in space: At a satellite conference yesterday Orbital ATK unveiled a new robotic satellite servicing system utilizing two new robots, the Mission Robotic Vehicle (MRV) and Mission Extension Pods (MEP), simpler yet also more sophisticated versions of its Mission Extension Vehicle (MEV) which is already planned for launch later this year.

Under the new approach, a Mission Robotic Vehicle, based on the MEV design, will carry 10 to 12 Mission Extension Pods. The Mission Robotic Vehicle would approach a customer’s satellite and use a robotic arm to attach a pod to that satellite. The pod would then take over stationkeeping, proving up to five years of additional life. The Mission Robotic Vehicle and Mission Extension Pods are intended to provide new solutions to customers that don’t need the full-fledged capabilities of the MEV. The pods have a shorter lifetime than an MEV and do not provide attitude control capabilities.

The new system, designed to be ready for service in 2021, largely incorporates existing technology. The Mission Robotic Vehicle is a version of the MEV and the Mission Extension Pods is based on Orbital ATK’s ESPASat small satellite bus.

One new technology will be the robotic arm. Tom Wilson, president of SpaceLogistics, the Orbital ATK subsidiary offering the satellite life extension program, said the company was considering technology from NASA as well as Europe. “We’ve got a couple of different options,” he said, but hasn’t yet made a decision on the specific technology.

Orbital ATK’s new design will certainly cost its customers a lot less, since its design that will allow them, with one launch, to place a robot in orbit capable of servicing up to twelve different satellites. You want to extend the life of your communications satellite by five years? You call Orbital ATK, and they use their already orbiting Mission Robotic Vehicle to install an extension pod on your satellite. This way they can spread the cost of the launch across a dozen different customers.

Blue Origin gets its fourth launch contract for New Glenn

Capitalism in space: Blue Origin has signed its fourth launch contract for putting satellites in orbit with its New Glenn rocket, this time with the Japanese company Sky Perfect JSAT.

Blue Origin now has satellite launch agreements with four companies. Last year, the company reported deals with Eutelsat, OneWeb and mu Space. Today Blue Origin said its memorandum of understanding with Thailand-based mu Space has been converted into a firm contract for a geostationary satellite launch.

No launch price was revealed, though I suspect the price is very competitive with SpaceX prices.

I expect that by the mid-2020s, these two companies will be completely dominating the commercial large satellite market. The one threat to that dominance will be whether that large satellite market will be able to compete with the new tiny cubesat and nanosat market that is only now beginning to develop. It could be that by the mid-2020s, almost all unmanned communications satellites will be small, and that the market for these big rockets will have shifted to manned space.

More likely, we will have a very vibrant smallsat market, a vibrant largesat market, and a emerging manned market, all vying for launch contracts from many different rocket companies. Things should be quite exciting.

NASA concludes design error caused June 2015 Falcon 9 launch failure

NASA’s independent investigation into the SpaceX’s June 2015 Falcon 9 launch failure has concluded, like SpaceX, that it was caused by the failure of a strut holding an internal tank, but unlike SpaceX the report cites a “design error” for that failure.

In simpler terms, the steel strut that SpaceX chose was not certified to be used in such conditions. Furthermore, SpaceX did not meet the 4:1 redundancy requirement that the manufacturer had instructed. Therefore, the IRT recommended that SpaceX applied greater care when certifying commercially sourced parts for flight.

Interestingly, the IRT also discovered another area of concern not directly related to the accident that arose during the investigation. The report found that the telemetry architecture on the upcoming “Full Thrust” version of the Falcon 9 included a new method of handling packets that increased latency, and thus vital data could have been lost in the event of a similar anomaly.

The IRT report finished by noting that all of the key findings in the report were addressed by SpaceX in time for the successful Jason-3 mission for NASA.

I suspect a political decision at NASA explains the timing of the release of this report, far later than normal. At this point the issues it raises are mostly moot, as SpaceX has upgraded the Falcon 9 and is no longer using the older version that failed on that June 2015 launch. Moreover, NASA has certified those upgraded rockets, which suggests they have reviewed the company’s methods and have decided it is now using parts that are properly certified.

However, the recent successful launch of Falcon Heavy has created a big threat to SLS. This report, released now, is certainly going to be used by SpaceX’s enemies to argue that it is dangerous to buy its heavy lift rocket. “Look, SpaceX is sloppy! It uses uncertified parts that cause its rockets to blow up!” I can see the op-eds, paid for covertly by the big space companies Boeing and Lockeheed Martin, being typed even as I write this.

NASA’s interim administrator to retire in April

NASA’s interim administrator, Robert Lightfoot, has announced that he plans to retire in April.

Lightfoot’s retirement leaves NASA without any leadership, as the Senate has shown no interest in confirming Trump’s candidate for the position, Congressmen Jim Bridenstine (R-Oklahoma).

All 49 Democrats in the Senate are expected to vote against to Bridenstine’s confirmation, and Sen. Marco Rubio (R-Florida) is also reportedly also opposed, Space News reported. Sen. John McCain (R-Arizona) is not in Washington as he undergoes treatment for cancer, leaving Bridenstine short of the 50 votes needed for confirmation.

Bridenstine is not a perfect choice, and I have reservations about his commitment to commercial space, but the reasons for the Democratic opposition is, as far as I can tell, the same as all their other opposition to every other Trump or Republican proposal: pure spite. “We hate it because of YOU!”

The lack of a politically appointed administrator at NASA however is not necessarily a bad thing, considering that the important stuff happening right now is not at NASA but in the private sector. Having NASA adrift for awhile might actually work to weaken NASA’s pork projects, SLS and Orion, that are in direct competition with private space.

Funding shortfall causes Planetary Resources to cut back

Because of their failure to close a round of investment fund-raising, Planetary Resources has been forced to cut back, including some layoffs and delaying several proposed later missions.

The delayed investment, though, forced Planetary Resources to lay off some of its employees. Lewicki declined to say how many were let go from a peak of 70 employees prior to the layoffs.

That setback also affects the schedule for future asteroid prospecting missions. In his conference talk, Lewicki showed a video of a planned mission where several small spacecraft, launched as secondary payloads, fly to near Earth asteroids to measure their water content. In past presentations featuring that video, company officials said the mission was scheduled for launch in 2020.

However, Lewicki didn’t state in this talk when that mission would launch, and acknowledged later the funding problems would delay it until some time after 2020. “The 2020 date was assuming we would get all the necessary financing on schedule last year,” he said.

To me, this article illustrates why Planetary Resources failed to obtain its investment funds. They pitch themselves as an asteroid mining company, but very little of what they are doing has anything to do with actual mining, or obtaining profits from that mining. At the moment, they remain an Earth observation company with capabilities not as good as a host of other similar companies expressly dedicated to this task.

I say this not because I am against asteroid mining, or think it cannot make a profit. I just think Planetary Resources has oversold itself, which can be deadly in the harsh competitive market.

Rocket Lab unaffected by Swarm/FCC kerfuffle

Rocket Lab is proceeding with preparations for its next and first commercial Electron rocket launch, despite the removal of four Swarm nanosats because the FCC had cancelled its launch license.

Rocket Lab spokeswoman Morgan Bailey said the matter was between Swarm and the FCC, and had not caused any delay to preparations for Rocket Lab’s next launch, which is tipped to take place in April. “For us, it doesn’t really create any issues.”

Its Electron rockets are designed to carry a payload of up to 150 kilograms, meaning the tiny Swarm satellites would only be a small part of any cargo.

It appears the launch will occur in April, though an exact date and a description of its payload has not yet been released.

Highlight video reel of Falcon Heavy launch

One of the creators of a television science fiction series has produced a highlight video, set to David Bowie’s “Life on Mars?”, of the first Falcon Heavy launch that shows some new footage of the core stage watery crash.

I have embedded the video below the fold. To me, the best part is the footage of the spectators, including the many children, wonder-struck by the launch. Some of that footage is very reminiscent of footage taken during the Apollo Saturn 5 launches in the late 1960s.

To the next generation: We are going to the Moon — and beyond. And this time we are going to stay.

FCC accuses satellite startup of launching satellites without a license

Four tiny nanosats built by a California startup that were placed in orbit by India’s PSLV rocket in January now appear to have been launched without an FCC license.

Swarm believes its network could enable satellite communications for orders of magnitude less cost than existing options. It envisages the worldwide tracking of ships and cars, new agricultural technologies, and low cost connectivity for humanitarian efforts anywhere in the world. The four SpaceBees would be the first practical demonstration of Swarm’s prototype hardware and cutting-edge algorithms, swapping data with ground stations for up to eight years.

The only problem is, the Federal Communications Commission (FCC) had dismissed Swarm’s application for its experimental satellites a month earlier, on safety grounds. The FCC is responsible for regulating commercial satellites, including minimizing the chance of accidents in space. It feared that the four SpaceBees now orbiting the Earth would pose an unacceptable collision risk for other spacecraft.

If confirmed, this would be the first ever unauthorized launch of commercial satellites.

The FCC denied the license because the nanosats were so small there is a fear they could become a space junk hazard. The FCC has now vacated an approved license for launching four more Swarm satellites on a Rocket Lab Electron rocket in April because, “The FCC believes that Swarm launched and is operating its original small satellites, despite having been forbidden to do so.”

If this story is true, it illustrates some incredibly stupid decisions by the people running Swarm. The FCC concerns here appear quite reasonable, and the company’s decision to ignore them now means that they might have gambled their entire company away. Moreover, this does harm to Rocket Lab, which has lost a customer.

Arianespace successfully places four communications satellites in orbit

Using a Russian Soyuz rocket and launching from French Guiana Arianespace today successfully launched four communications satellites.

The leaders in the 2018 launch standings:

7 China
5 SpaceX
3 Japan
3 ULA
2 Russia
2 Arianespace

For the purpose of these rankings, I consider the Soyuz rocket, launched from French Guiana, an Arianespace vehicle, since it is marketed, assembled, and launched by that company.

Vector to launch two cubesats from Alaska later this year

Vector yesterday announced that it plans to complete its first orbital launch from Alaska later this year, placing two commercial cubesats in orbit.

Their original plans had been to do five suborbital test flights, each pushing closer to orbital, with the last possibly reaching orbit. They’ve so far completed two of these five launches. Now it appears they are bypassing the last three test launches and are going straight to orbit on their next launch, and are pitching it as an operational commercial flight. I hope they have their engineering together. I also wonder if it might be wiser to do what Rocket Lab did, which is to tout its first orbital attempts as tests, and only tests, to lower expectations. That made them look good when the second test reached orbit successfully.

The change of plans might also be because Vector is feeling the competition pressure from Rocket Lab and the numerous other smallsat rocket companies that appear to be coming out of the woodwork. They need to get operational to put themselves in the forefront of this new launch industry.

Once again, I hope they have their engineering together. It would be a shame to screw up merely because they pushed things too much, when they right now are ahead of most other smallsat rocket companies.

Trump plugs private space at cabinet meeting

At the beginning of a cabinet meeting yesterday Trump spent some time talking about the recent successes in commercial space.

Three quotes of interest:

  • “Rich guys, they love rocket ships. And that’s good. Better than us paying for them.”
  • “I notice the prices of the last one they sent. It cost $80 million. If the government did it the same thing would have cost probably 40-50 times that amount of money. I mean literally. … I’m so used to hearing different numbers from NASA.”
  • We’re really at the forefront, nobody is doing what we’re doing. I don’t know if you saw, with Elon, the [Falcon Heavy] rocket boosters where they’re coming back down. To me that was more amazing than watching the rocket go up. ‘Cause I’ve never seen that before. Nobody has seen that before…. They landed so beautifully.

Not unusually, Trump gets some details wrong but understands the essentials, much to the terror of the big space contractors of SLS (Boeing) and Orion (Lockheed Martin). SpaceX will charge $90 million for the launch of a reused Falcon Heavy (using three reused first stages). Estimates for the cost of a single SLS launch are difficult to estimate. In Capitalism in Space I had estimated the project’s overall cost, based on Congressional appropriations, to be about $25 billion come its first manned flight, but that cost is likely going up because the first flight will be delayed. Trump’s numbers estimate a cost of about $4 billion for a single launch, which is a reasonable number considering SLS is not expected to launch more than once a year, and SLS’s annual appropriations, about $3 billion, which will not change once it is operational.

In other words, SLS is an overpriced rip-off, especially now that we have a cost-effective alternative.

Yesterday there were two op-eds warning everyone of the dangers of giving government money to SpaceX.

The first worries that Musk is a “master manipulator” and the king of “crony capitalism” and that we shouldn’t be blinded by this single Falcon Heavy success. Others, like ULA, are better companies to depend on. The second warns that the government mustn’t become so blinded by SpaceX’s Falcon Heavy launch that it decides to invest money in the company.

Both op-eds are laughable. Compared to the crony capitalism of Boeing and Lockheed Martin, which have sucked almost $50 billion from the taxpayers for SLS/Orion while producing no flights, Elon Musk is a piker. And no one has ever suggested investing in SpaceX, like a venture capitalist. The Trump administration has merely proposed buying its rockets to launch future deep space missions, in order to save the taxpayers a lot of money.

There is real fear and terror in the bowels of big space and in the swamp in Washington. Elon Musk and the Falcon Heavy have put it there. Increasingly, it is becoming plainly obvious that SLS is a big over-priced boondoggle that we cannot afford, and Trump’s comments yesterday indicate that this fact is finally beginning to be politically acceptable.

Another smallsat rocket company enters the market

Capitalism in space: A new Australian smallsat rocket company, Gilmour Space Technologies, has successfully test fired a new hybrid rocket engine.

This orbital-class rocket engine, developed by Australia and Singapore-based Gilmour Space Technologies (www.gspacetech.com), has successfully achieved 70,000 newtons (70 kilonewtons or 15,700 pounds-force) of thrust in what could be the world’s largest successful test fire of a single-port hybrid rocket engine. “These results prove that we have the core technology needed to enable low-cost small satellite launches to space,” said its CEO & Founder, Adam Gilmour. The company’s mission: to carry payloads weighing up to 400 kg to low earth orbit (LEO) from 2020.

Unlike the vast majority of commercial rockets today, which use either solid- or liquid-fuelled engines, Gilmour Space is pioneering new hybrid-engine rockets that combine a liquid oxidiser with a proprietary multi-material 3D printed solid fuel. Indeed, the Queensland-based company first made headlines in 2016 when it successfully test launched a subscale rocket to an altitude of 5km using its 3D printed rocket fuel.

The static fire test, which can be seen in a video at the link, was very short, less than 10 seconds. Since one of the big problems of hybrid engines has been to get them to fire smoothly and precisely for long periods of time, I remain skeptical. They might have some good engineering here, but I don’t yet see the makings of a rocket.

A detailed look at Rocket Lab’s Electron rocket

Link here. The article provides some details about the first two launches, but its most interesting section discusses the rocket’s Curie kick stage.

“We kind of made a philosophical decision in that we weren’t going to do multiple burns on the second stage because what that does is it puts the second stage in orbit, in high orbit,” said Mr. Beck. “What we’re trying to do here is launch frequently, and the way that we’ve designed our trajectories is that the second stage will always go into a transfer orbit, which is a nice elliptical orbit, where it deorbits very quickly, and then we use the kick stage to do any orbit raising or circularization.”

This design was specifically chosen so that Rocket Lab would not put large second stages into orbit and would fly responsibly by deorbiting Electron’s second stage quickly so as not to contribute significantly to the space debris environment. “We build this infrastructure in orbit in a sustainable way, and leaving second stages in high orbits is not really conducive to that. So what it means is … we’re just putting a little Curie module up into orbit, and we also have deorbit capability on that, too.”

Moreover, the Curie kick-stage was a direct result of Rocket Lab talking to and listening to their customer base – who wanted to make sure that on ride share missions of Electron that all payloads were separate safely and not re-contact other small satellites launched/deployed on that same mission.

No word yet on when they will fly next, though it sounds as if there will be a number of launches this year, at an ever-increasing pace.

SpaceX successfully launches commercial communications satellite

SpaceX tonight successfully launched a commercial communications satellite. They did not recover the first stage because the seas were too rough to send out the drone ship.

The leaders in the 2018 launch standings:

7 China
5 SpaceX
3 Japan
3 ULA
2 Russia

Though I have removed Rocket Lab as an American company, crediting it instead to New Zealand, the U.S. still has 8 successful launches total, one more than China.

Testing of Blue Origin’s BE-4 rocket engine continues

Though he released few details, a Blue Origin company official noted at a conference last week that the company has been continuing its tests of the BE-4 engine.

“We’re getting longer duration burn times. We’re going though validating the turbomachinery very closely,” said Jim Centore, group lead for orbital mission operations at Blue Origin, during a panel discussion on launch systems at the conference. Centore didn’t disclose many details about those tests, such as thrust levels or the burn times, either of individual tests or cumulatively. “We’re continuing to make good progress,” he said. “We’ll continue that for the next several months.”

The BE-4 is the linchpin for numerous other future rockets. Blue Origin wants to use it for building its New Glenn rocket. ULA is considering it as the first stage engine for its Vulcan rocket. In both cases, design and construction of the rockets themselves can’t really proceed until the engine is locked down.

Interorbital completes static fire test of upper-stage engine

Capitalism in space: The smallsat rocket company Interorbital (IOS) today released a short video showing a successfully static fire test of the upper-stage engine for its Neptune rocket.

The IOS rocket team successfully completed the first test of Interorbital’s NEPTUNE series launch vehicle’s liquid upper-stage rocket engine (GPRE 0.75KNTA). Engine performance was well within its design parameters, generating a sea-level thrust of 750 pounds and a sea-level specific impulse of 245 seconds. This translates to a thrust of 1,000 pounds and a specific impulse of 300 seconds in a vacuum (with expansion nozzle). The ablatively-cooled rocket engine is powered by the hypergolic combination of White Fuming Nitric Acid (WFNA) and Turpentine/Furfuryl Alcohol. These high-density storable auto-igniting propellants power all IOS liquid rocket engines. Interorbital’s N1 launch vehicle utilizes two GPRE 0.75KNTA engines for its second stage and a single GPRE 0.75KNTA engine for its third stage.

I have embedded the video below the fold. This is the first real news update from Interorbital in months. In April 2017 they looked like they were close to a launch, but until today there were no further updates. Part of the issue appears that they changed their approach for manufacturing their rocket in order to save cost, and this might have thrown a wrench in their schedule.

Stratolaunch completes initial taxi tests

This past weekend Stratolaunch successfully completed its second series of taxi tests, reaching a speed of 40 knots (46 miles per hour) as it moved down the runway.

[I]n December Stratolaunch capped off the year with a successful low-speed taxi test. During the taxi, the vehicle reached a top speed of 28 miles per hour (45 kilometers per hour) as it headed down the runway. Following the test, Aircraft Program Manager George Brugg stated, “This was another exciting milestone for our team and the program. Our crew was able to demonstrate ground directional control with nose gear steering, and our brake systems were exercised successfully on the runway. Our first low-speed taxi test is a very important step toward first flight.”

Last weekend, Sratolaunch kicked off 2018 with two days of additional taxi tests. Most notably, the tests included reaching the maximum taxi speed of 40 knots (46 miles per hour). According to Allen, these tests allowed the team to “verify control responses.”

There is a tiny 35 second video of this last test at the link.

The article provides a lot of details about Stratolaunch and its future, including the suggestion that the giant airplane could become the main launch platform for Orbital ATK’s Pegasus rocket. Pegasus presently has only one launch listed on its manifest, using its L1011 Stargazer airplane.

Smoking battery at Rocket Lab facility

Capitalism in space: Rocket Lab is investigating why one of the rocket batteries for its Electron rocket started smoking over the weekend.

Rocket Lab is investigating what caused a rocket battery to overheat and start smoking at its manufacturing facility near Auckland Airport on Sunday night. Rocket Lab spokeswoman Morgan Bailey said fire emergency services were called as a precaution to its site in Mangere at 7pm on Sunday after a battery on an Electron rocket overheated and started smoking.

She said she did not know what action was being made on the rocket when the battery overheated, but the company was looking into it.

No one was hurt in the incident.

They are clearly being tight-lipped about this, partly because of the bad press it might cause and partly because they don’t wish to reveal proprietary information.

Note that this article has me rethinking Rocket Lab as an American company. Based on this article their operations and manufacturing are both in New Zealand. It seems that even if the company was conceived and officially incorporated in the U.S., the rocket is a New Zealand born baby.
