JAXA reveals cause of Epsilon rocket failure

9:41 am

Japan’s space agency JAXA yesterday announced the results of its investigation into the launch failure of its Epsilon rocket on October 12, 2022, pinpointing the cause to the attitude control system in the solid-fueled second stage.

After the launch of the three-stage solid-propellant rocket, the first-stage rocket engine worked normally and was detached as scheduled. The second-stage engine showed no combustion problem, but an abnormal attitude was confirmed immediately after the engine used up its fuel, JAXA told a science ministry meeting.

The attitude was off to the lower right by some 21 degrees more than planned, according to JAXA. The space agency judged that the rocket could not enter Earth orbit and sent a self-destruction signal to the rocket 6 minutes and 28 seconds after liftoff.

Analyses of flight and other data showed that one function of a reaction control system, which uses thrusters to control attitude and other factors, did not work after the combustion of the second-stage engine, according to JAXA.

Epsilon is Japan’s attempt to produce a low cost rocket, though it has only launched a handful of times since its first launch in 2013, suggesting it has not been attracting many customers.

OneWeb gets deal to provide internet on airplanes

11:13 am

The competition heats up: OneWeb will partner with Panasonic Avionics — which already provides WiFi for 70 airlines — to use the satellite constellation as part of its airline service.

Adding LEO capabilities from OneWeb would enable pole-to-pole coverage with forward link speeds approaching 200 megabits per second (Mbps), according to Panasonic, and return link speeds up to 32 Mbps. Ben Griffin, OneWeb’s vice president for mobility services, said the deal enables the LEO operator to leverage Panasonic’s “reputation, expertise, and reach” to bring its network to airlines.

The agreement also paves the way for OneWeb’s services to be integrated into existing in-flight entertainment systems that Panasonic provides for aircraft.

Both OneWeb and Starlink now have deals to provide internet capabilities for airlines. The competition can only mean the cost to consumers on those planes will likely drop.

Meanwhile, India’s government commercial launch division, NSIL, is prepping a GSLV rocket to launch 36 OneWeb satellites for an October 22nd launch. This will be the first launch replacing the Russians as OneWeb’s launch provider. The launch path over the ocean (with a turn to avoid dropping debris on Sri Lanka) can be seen here.

Rocket startup Orbex raises another $45 million

9:22 am

The British-based rocket startup company Orbex announced today that it has successfully raised another $45 million in private investment capital, adding to the $63 million it had previously raised.

Orbex is developing Prime, a small launch vehicle designed to place up to 180 kilograms into low Earth orbit. The vehicle, built by the company at a factory in Forres, Scotland, will launch initially from Space Hub Sutherland, a new launch site under development in northern Scotland.

“With Orbex, we will have a rocket assembled in Scotland, launching from Scotland and likely transporting satellites built in Scotland into orbit,” said Nicola Douglas, executive director of the Scottish National Investment Bank, in a statement. “We’re building a full end-to-end commercial space ecosystem in Scotland and we’re proud to play our part in this funding round.”

The company is targeting 2023 for its first launch from the new spaceport in Sutherland, Scotland.

Both the Pentagon and Europe are looking for ways to fund Starlink for the Ukraine

9:13 am

According to an article in Politico today, both the U.S. military and the European Union (EU) are investigating ways in which either could fund the cost for providing Starlink to the Ukraine, rather than remaining a voluntary donation by SpaceX.

The most likely source of funding, several government and industry officials said, would be the Ukraine Security Assistance Initiative, which has been used to acquire a range of weapons and services for the Ukraine war effort.

The Starlink issue also came up during a meeting of the European Union’s foreign ministers on Monday, as the countries discussed whether to contribute funding to ensure Ukrainians keep their access to the service. Lithuanian Foreign Minister Gabrielius Landsbergis told POLITICO after the meeting that EU foreign policy chief Josep Borrell raised the subject of paying to keep the service running in Ukraine, but the effort is still in its early stages.

It also appears there are discussions to find a back-up to Starlink. At the moment however the only possible option would be OneWeb, and it is not clear its design would work for the soldier in the field.

Regardless, considering the amount of cash being thrown at military contractors for the war — much of which is likely worthless and simply pork — it seems entirely reasonable to devote some to Starlink, a technology that has actually made a difference.

ESA looking to SpaceX to launch Euclid space telescope

9:02 am

Capitalism in space: Having lost its Soyuz launch vehicle for its Euclid space telescope because of the Russian invasion of the Ukraine, the European Space Agency (ESA) is now looking at SpaceX as a possible option.

At a meeting of NASA’s Astrophysics Advisory Council, Mark Clampin, director of the agency’s astrophysics division, said his understanding is that the European Space Agency was leaning towards launching its Euclid mission on a Falcon 9 in mid to late 2023.

NASA is a partner on Euclid, a space telescope that will operate around the Earth-sun L-2 Lagrange point 1.5 million kilometers from Earth to study dark energy, dark matter and other aspects of cosmology. The 2,160-kilogram spacecraft was to launch on a Soyuz rocket from French Guiana in 2023.

Europe has for years used its own rockets for its science missions. However, right now the Falcon 9 appears the only option. The last launches of Europe’s Ariane-5 rocket are already assigned, and the new Ariane-6 rocket has not yet flown, is behind schedule, and its early launches are also already reserved.

Nor does ESA have other options outside of SpaceX. Of the rockets powerful enough to do the job, ULA’s Atlas-5 is also being retired, and the Vulcan rocket is as yet unavailable. Blue Origin’s New Glenn is years behind schedule, with no clear idea when it will finally launch.

A final decision is expected soon. ESA could either go with SpaceX, or simply delay several years until Ariane-6 is flying.

If SpaceX gets the job however it will once again demonstrate the value of moving fast in a competitive environment. While its competitors have dithered and thus do not have their rockets ready, SpaceX has been flying steadily for years, so it gets the business.

Russia launches military satellite using Angara rocket; new global record for launches

9:00 am

Russia today successfully launched a classified military satellite using its new Angara rocket in its Angara-1.2 configuration.

Like ArianeGroup’s Ariane-6, Angara is modular, so depending on the payload’s launch needs, it can have additional strap-on boosters, from none to four. This launch had no side boosters at all.

The launch was the 135th of 2022, passing the record set last year of 134 successful launches for the entire world in one year. In 2022 the record was broken in the last week. This year the record has been broken two and a half months before the end of the year. Based on the number of planned launches for the rest of the year, 2022 is likely to easily exceed 150 launches.

And the reason this number going through the roof is because of the advent of private enterprise, private ownership of rockets, and intense competition. New rocket companies are sprouting up everywhere worldwide, each with their own rocket competing aggressively for business by lowering costs. The lower costs make it possible for more satellite companies to find financing because making money will be easier. This in turn results in more customers for the rocket companies, which encourages more competition which pushes the price down further.

The cycle feeds on itself, and will only end when the full potential of space exploration is reached. And since that potential is literally endless, this growth for the human race is also endless. The only thing that could stop it is if human civilization decides to stop it, intentionally, either from willful ignorance or fear.

The leaders in the 2022 launch race:

47 SpaceX
45 China
15 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 67 to 45 in the national rankings, but now trails the rest of the world combined 68 to 67.

China launches military satellite

8:31 am

Using its Long March 2D rocket, China today successfully launched a satellite in its classified Yaogan series, suspected to be for military reconnaissance.

In fact, so little is known about the Yaogan satellites that we aren’t even sure how many were placed in orbit today. Normally a Yaogan launch puts three satellites into orbit (which is what this Space.com article assumes). The story from China’s state-run press above however does not say this at all. Instead, it implies that only one Yaogan satellite was launched.

Regardless, the leaders in the 2022 launch race:

47 SpaceX
45 China
14 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 67 to 45 in the national rankings. It is now tied with the entire world combined 67 to 67. This launch today also brings the launch total this year to 134, which ties the record for the most successful launches in a single year, set last year. With two and a half months still to go, 2022 should end up breaking that record significantly.

Skyrora’s first suborbital rocket launch fails shortly after liftoff

9:57 am

Capitalism in space: The first launch attempt of a suborbital rocket for Skyrora, a rocket startup from the United Kingdom, failed on October 8, 2022 shortly after liftoff.

The launch was from Iceland, with the rocket crashing in the ocean about 1,600 feet from the pad. No one was injured. The rocket, Skylark-L, was designed for a suborbital flight to test equipment that will be used in the orbital rocket, Skyrora-XL.

Skylark-L is Skyrora’s 11m suborbital rocket, capable of reaching 4x the speed of sound and an altitude of over 125 km. 70% of the technology tested in the Skylark-L launch attempt will be applied to the systems of the Skyrora-XL vehicle, providing a key incremental learning opportunity to increase technological readiness ahead of vertical orbital launch next year.

As this was an engineering flight, the failure is actually a good thing, as it will provide Skyrora’s engineers information about changes needed to make their rocket function properly. Don’t expect that first orbital launch however next year, as the company promises. These things always take longer than expected.

Watching return of ISS crew on Freedom

9:40 am

The SpaceX manned capsule Freedom has undocked from ISS, carrying three astronauts completing a six month mission, with a scheduled splashdown planned for 4:50 pm (Eastern) off the western coast of Florida.

I have embedded NASA’s live stream below, for those that wish to watch. Note that though NASA inserts itself into this event, once the spacecraft has left ISS everything — including all workers involved in splashdown operations — is solely under the supervision of SpaceX, with NASA’s participation only that of a customer, albeit a very powerful one. This is a capsule and splashdown designed, built, run, and most important, owned by a private American company, not the government.

Ispace targets November 9-15 launch window for first commercial lunar lander

9:07 am

The private Japanese company Ispace has now scheduled the launch of its commercial lunar lander Hakuto-R on a SpaceX Falcon 9 rocket for a November 9-15, 2022 launch window.

Though the lander’s primary goal is to see if this lander will work, it also includes several customer payloads, the most significant of which is the Rashid rover from the United Arab Emirates. Rashid, which is about the size of a Radio Flyer red wagon, will operate for one lunar day, about two weeks. While its main mission is to test the engineering and to train the engineers who built it, it will have two cameras for taking pictures. In addition, on its wheels are test adhesive patches of different materials, designed to see how each material interacts with the Moon’s abrasive dust.

Dennis Tito signs deal to fly on 2nd manned Starship mission around Moon

10:26 am

Capitalism in space: Dennis Tito, the first tourist to fly in space and now 82-years-old, has signed a deal with SpaceX for both him and his wife Akiko to fly on 2nd manned Starship mission around Moon.

His weeklong moonshot — its date to be determined and years in the future — will bring him within 125 miles (200 kilometers) of the lunar far side. He’ll have company: his wife, Akiko, and 10 others willing to shell out big bucks for the ride.

Tito won’t say how much he’s paying; his Russian station flight cost $20 million.

The couple recognize there’s a lot of testing and development still ahead for Starship, a shiny, bullet-shaped behemoth that’s yet to even attempt to reach space. “We have to keep healthy for as many years as it’s going to take for SpaceX to complete this vehicle,” Tito said in an interview this week with The Associated Press. “I might be sitting in a rocking chair, not doing any good exercise, if it wasn’t for this mission.”

The bottom line is that this deal, combined with the two other passenger Starship deals SpaceX has already signed, demonstrates that there is a solid market for Starship, even before its first launch. Expect that market to boom once the rocket begins operations.

Will Tom Cruise ever actually shoot a movie in space?

10:17 am

Capitalism in space: According an interview last week from Donna Langley, chairman of Universal Film Entertainment Group, the company is arranging for Tom Cruise to film scenes of a movie on ISS, where Cruise will also be the first non-professional to do a spacewalk.

“That’s the plan. We have a great project in development with Tom that does contemplate him doing just that,” she said, “taking a rocket up to the space station and shooting and hopefully being the first civilian to do a spacewalk outside of the space station.”

She said the film request came from Cruise directly and that he is in close collaboration with director Doug Liman, who previously worked with Cruise in 2014’s “Edge of Tomorrow” and is also known for “The Bourne Identity” franchise, “Mr. and Mrs. Smith” and “Jumper.”

This claim might be true, but producers associated with Cruise have been making such claims now for three years, none of which have come even close to happening. I am sure the project is being discussed, and even pushed hard, but based on what has actually happened, this announcement could simply be a way to generate buzz for Cruise’s next film, whether or not he flies.

Nonetheless, I fully believe that Cruise is the source of this idea, and wants to do it, given his habit of doing his own stunts in his movies.

SpaceX fully stacks Starship/Superheavy in preparation for launch

9:53 am

Starship about to be stacked on Superheavy
Starship about to be stacked on Superheavy, using
the launch tower’s chopstick arms. Click for full image.

For the first time in six months SpaceX engineers have stacked Starship prototype #24 on top of Superheavy prototype #7, with the intention of running a dress rehearsal countdown and a full static fire test of Superheavy’s 33 engines, all in preparation for the first orbital test flight before the end of this year.

According to CEO Elon Musk, Booster 7 and Ship 24 will attempt Starship’s first full-stack wet dress rehearsal (WDR) once all is in order. The prototypes will be simultaneously loaded with around 5000 tons (~11M lb) of liquid oxygen and methane propellant and then run through a launch countdown. Diverging just before ignition and liftoff, a WDR is meant to be more or less identical to a launch attempt.

…If the wet dress rehearsal goes to plan, SpaceX will then attempt to simultaneously ignite all 33 of the Raptor engines installed on Super Heavy B7, almost certainly making it the most powerful liquid rocket ever tested. Even if all 33 engines never reach more than 60% of their maximum thrust of 230 tons (~510,000 lbf), they will likely break the Soviet N-1 rocket’s record of 4500 tons of thrust (~10M lbf) at sea level. It would also be the most rocket engines ever simultaneously ignited on one vehicle. SpaceX will be pushing the envelope by several measures, and success is far from guaranteed.

Depending on the results of these tests, the stacked rocket will either require further modifications, or could even proceed directly to launch.

We are thus seeing a true race between SpaceX’s privately developed and funded rocket and NASA’s government developed and funded SLS rocket. Which will launch first? Right now the race is neck-and-neck, though that is deceiving since SpaceX began development twelve years after NASA started work on SLS. Even if SLS launches first, SpaceX will have clearly shown that private enterprise does things faster (7 years vs 18 years) and for far less money (about $9 billion vs $46 billion).

New rocket startup focusing on new concepts to make upper stage reusable

9:22 am

Capitalism in space: Another new rocket startup, Stoke Space, is working to develop a new innovative reusable design for its upper stages.

Most commonly, a traditional rocket has an upper stage with a single engine. This second-stage rocket engine has a larger nozzle—often bell-shaped—to optimize the flow of engine exhaust in a vacuum. Because all parts of a rocket are designed to be as light as possible, such extended nozzles are often fairly fragile because they’re only exposed above Earth’s atmosphere. So one problem with getting an upper stage back from Earth, especially if you want to use the engine to control and slow its descent, is protecting this large nozzle.

One way to do that is to bury the engine nozzle in a large heat shield, but that would require more structure and mass, and it may not be dynamically stable. Stoke’s answer was using a ring of 30 smaller thrusters. (The tests last month only employed 15 of the 30 thrusters). In a vacuum, the plumes from these nozzles are designed to merge and act as one. And during reentry, with a smaller number of smaller thrusters firing, it’s easier to protect the nozzles.

Will this company succeed? Who knows? It is presently very early in development. However, that its founders are former engineers from SpaceX and Blue Origin is encouraging, especially based on this comment about why the Blue Origin guy, Andy Lapsa, left that company:

“I love Jeff [Bezos]’s vision for space,” Lapsa said in an interview with Ars. “I worked closely with him for a while on different projects, and I’m basically 100 percent on board with the vision. Beyond that, I think I would just say that I will let their history of execution speak for itself, and I thought we could move faster.”

Lapsa apparently was part of the exodus of high level managers and engineers that occurred at Blue Origin after Bezos hired Bob Smith as CEO. All complained of the company’s far-too-cautious management style under Smith.

Engineers regain full control of CAPSTONE

9:21 pm

After a month of careful tests and analysis, engineers today successfully regained full control of the CAPSTONE lunar orbiter, on its way to the Moon.

The most likely cause of the anomaly was identified as a valve related issue on one of the spacecraft’s eight (8) thrusters. The partially open valve resulted in thrust from the associated thruster whenever the propulsion system was pressurized. To attempt a recovery from this condition, the mission team conducted multiple tests on the vehicle and evaluated extensive telemetry and simulation data and then formulated a plan for attempting recovery of the vehicle’s full 3-axis control.

This recovery sequence was uploaded to the spacecraft yesterday (Thursday) and was executed early this morning (Friday 10/7). Initial telemetry and observation data after the recovery attempt points to a successful recovery of the system which has now regained 3-axis attitude control. The updated spacecraft attitude has oriented the spacecraft solar arrays to the Sun and implemented an orientation for the downlink antennas which significantly improves data downlink performance as compared to the pre-recovery attitude.

The spacecraft is not out of the woods yet. The engineers still need to figure out how to do future course corrections with “the possible presence of a valve that remains partially open.”

Nonetheless, that they have successfully regained full control means they have a very good handle on the issue, which bodes well for the lunar orbital insertion maneuver on November 13, 2022.

Startup smallsat rocket company signs spaceport deal with Brazil

9:02 am

The new colonial movement: A Canadian startup smallsat rocket company, C6 Launch Systems, has not only signed a spaceport deal with Brazil to build its own launchpad at that country’s Alcantara Space Center, it has also won its first launch customer.

First, the launchpad is for C6’s rocket, which is unnamed and designed to launch cubesats. The company webpage says they are aiming for suborbital flights in 2021 and orbital flights in 2022, but it is unclear if it has launched anything at this point.

Nonetheless, Brazil is very clearly teaming up with C6. The Brazilian air force hired it to build a launch pad, a Brazilian company, Concert Technologies, has awarded it a launch contract.

Concert Technologies S.A. who are developing a new small satellite constellation have signed a a non-exclusive letter of intent to launch three small satellites with C6 Launch. The broad agreement allows for Concert Technologies to schedule more launches to maintain and expand their high-resolution Earth Observation (EO) constellation.

It appears Concert’s satellites will be targeting both the Earth imagery market as well as communications services in the “internet of things.”

Important Roscosmos official endorses continuing cooperation with US in space

12:28 pm

In a clear sign of the distinct change in atmosphere since the removal of Dmitry Rogozin as head of Roscosmos, the executive director of human space flight programs at Roscosmos, Sergei Krikalev, yesterday endorsed the longstanding cooperation between the U.S. and Russia in space.

Krikalev’s comments came after the launch yesterday of Endurance with one Russian astronaut as part of its four-person crew.

At a briefing after the Oct. 5 launch of the Crew-5 mission from the Kennedy Space Center, Sergei Krikalev, executive director of human space flight programs at Roscosmos, emphasized long-running cooperation between the United States and Russia in civil space, cooperation that has been strained since Russia’s invasion of Ukraine in February.

“We just continue what we started many years ago in 1975 when the Apollo-Soyuz crew worked together, and now we continue our cooperation,” he said after mentioning a “new phase of cooperation” with the exchange of seats between NASA and Roscosmos.

To understand the importance of Krikalev’s comments, you must also understand the context. First, Krikalev is a very significant figure in the history of Russia. He was called the last Soviet citizen, having been stranded on Mir an extra few months when the Soviet Union fell in 1991. Then he was the first Russian to fly on the shuttle, followed later by being on the first mission to ISS, when it was only two modules.

Since his retirement as an active astronaut, he has become the man in charge of Russia’s manned program, where he clashed with Rogozin several times over policy. His opposition to Rogozin almost certainly was a factor in Rogozin’s removal.

Krikalev’s endorsement of continuing the U.S-Russian partnership only cements that partnership, especially because Krikalev himself is a dyed-in-the-wool communist at heart. At least, he said so emphatically when I interviewed him at length in 2003 for Leaving Earth. I doubt his mind has changed in this matter, though his relentless honesty as an engineer has probably shaken his dedication to that failed ideology in subsequent years.

Nonetheless, his standing in Russia gives any statement he makes great weight. Expect more efforts by the Russians to ease tensions with the U.S., though their chances of success will be limited as long as Russia is continuing its unprovoked invasion of the Ukraine.

Engineers still struggling to regain full control of CAPSTONE

10:50 am

Though its batteries are now getting charged by the Sun, engineers have still not regained full control of the smallsat lunar orbiter CAPSTONE, presently on its path towards the Moon.

As per the latest update:

The CAPSTONE mission team is continuing to work towards recovery of the spacecraft full three-axis control. This work includes collecting information from the spacecraft, running simulations, and refining recovery plans. The vehicle remains stable and power positive in its current configuration.

In other words, they’ve got the spacecraft oriented so that its solar panels can gather enough sunlight to charge the batteries, but its attitude remains incorrect and they do not yet have CAPSTONE fully under their control.

The spacecraft arrives in lunar orbit on November 13, 2022. At that time however it will have to do an engine burn to enter lunar orbit, and if full control is not regained by then this burn will not be possible because engineers will not be able to point it correctly.

Falcon Heavy to finally launch again?

8:57 am

After three years of delays due to payload issues, it now appears that the next Falcon Heavy launch will likely occur near the end of October.

The tentative date is October 28th, but this is not yet confirmed. Though a manifest of a half dozen Falcon Heavy launches has existed since 2019, and most were originally scheduled for launch in 2020-2021, none has taken place, all supposedly because of payload delays not issues with the rocket itself.

SpaceX officials are now saying that it plans to complete six Falcon Heavy launches within the next twelve months. Two are for the military, three for commercial communications companies, and the last is the Psyche mission for NASA. This last launch is delayed because of software issues discovered in June, only a few weeks before launch. Whether it can fix these issues in time for a new July 2023 launch window remains questionable.
