COVID-19 and launchpad issues delay Ariane 6

July 10, 2020 at 10:00 am Robert Zimmerman Points of Information

The European Space Agency (ESA) confirmed today that the first launch of Arianespace’s Ariane 6 rocket will be delayed at least six months, to late 2021, due to lock downs related to the Wuhan flu panic, as well as construction issues at the rocket’s new launchpad.

“While we know that the maiden flight will not take place before the second semester of 2021, we cannot at this moment precisely quantify the delay, and we cannot provide an exact launch date,” Daniel Neuenschwander, ESA’s director of space transportation, said according to an ESA translation of remarks at a July 9 press event provided to SpaceNews. The French Association of Professional Journalists in Aeronautics, organized the event at ArianeGroup’s headquarters in Paris.

ESA hopes to have greater clarity on the delays in a few months, he said, according to the ESA translation.

It bodes bad for this rocket that they, at this time, have so little handle on the issues and the length of the delays.

Launch failure for China’s new Kuaizhou-11 rocket

July 10, 2020 at 9:49 am Robert Zimmerman Points of Information

For reasons not yet specified, China’s new Kuaizhou-11 rocket today failed on its inaugural launch.

Many reports will say that this is a commercial rocket developed by the private company Exspace. That is not true. Like all Chinese aerospace companies, they do their work wholly under the supervision of the Chinese government.

The development of the KZ-11 began in 2015, with a maiden launch originally scheduled for 2018. The rocket is developed by China Aerospace Science and Technology Corporation (CASIC) and commercialized by the China Space Sanjiang Group Corporation (Expace).

The launch vehicle can loft a 1,500 kg payload into a Low Earth Orbit (LEO) or 1,00 kg to a 700 km sun-synchronous orbit.

The KZ-11 solid launch vehicle adopts a mobile launch platform, integrated power supply equipment, test and launch control facilities, aiming facility and temperature control facility, to carry vehicles from the technical support center to launch site, complete temperature control of payload, vehicle test and launch.

CASIC is in many ways China’s equivalent of NASA. And everything described in the last paragraph above, from solid rockets to mobile launches, are technologies developed expressly for military purposes. China will not let such things out for commercial companies to use however they wish, no matter what they claim.

Midnight repost: Switching to Linux

July 9, 2020 at 11:59 pm Robert Zimmerman Essays And Commentaries

The tenth anniversary retrospective of Behind the Black continues: My contempt for Microsoft and its terrible Windows operating system is quite well known. I successfully switched to Linux back in 2006 and have never regretted it.

After seeing a number of my posts noting the advantages of Linux (or anything) over Windows, one of my readers, James Stephens, offered to write a series for Behind the Black describing step-by-step the process by which one gets and installs Linux on either a desktop or laptop computer. Below are the links to this series. I have since used it myself as a guide to convert two used Windows 7 notebooks (purchased for about $35 each) to my favorite flavor of Linux, both of which I use regularly as my travel computers.

I wish more people would do the same. I am sure almost everyone has an old computer they don’t use anymore. It will work like new with Linux. Dig it out, follow James’ instructions, and free yourself from Windows. I guarantee you will not be disappointed.

Falcon 9 landing leg falls during retraction

July 9, 2020 at 10:15 am Robert Zimmerman Points of Information

Capitalism in space: During the processing to bring a used Falcon 9 first stage back to its hanger after its June 30th launch, one of the landing legs unexpectedly fell back to the ground during retraction.

I have embedded the video of the incident, cued to the event, below the fold. No one was hurt, and it appeared that nothing was damaged. It appears it happened because a cable holding the leg vertical snapped just before the leg got latched in place on the side of the rocket.

Air Force looking to buy flying cars

July 7, 2020 at 9:35 am Robert Zimmerman Points of Information

The Air Force is looking to buy commercially-made flying cars designed using drone technology.

The advantages of vertical landing and take-off are many. For example, they would not need runways that are targets and must be defended. They can take off and land practically anywhere. In the past however the cost and practicality of making an airplane do this has been a major obstacle.

Normally I would see an article like this in the military press as simply a lobbying effort by a government agency to garner a bigger budget for itself. That still might be the case, but this part of the Air Force’s proposal stood out:

Because a key aim of Agility Prime is to work with commercial industry, there are currently no plans to modify the design of the orbs for military use or arm them for strike missions. “We will not put any military unique requirements on them because the last thing you want to hear as a commercial backer of one of these companies is that the military is coming in and changing a vehicle away from a type that would have domestic use,” Roper said. “We want to create a supply chain in the U.S. that is dual commercial and military.”

In other words, the Air Force wants to buy these unmodified from commercial civilian companies, both to save money and speed utilization. They have issued the general specs for the two types of vehicles they want (one larger than the other) and are accepting bids from private companies for delivery.

If true and if the Air Force sticks to this policy (which is essentially the approach I advocated for NASA in my 2017 policy paper Capitalism in Space), they hope to have these vehicles flying operationally by 2023, and at a cost of only “a few hundred thousand dollars to a few million dollars per unit.”

Update on Starship test program: First tests for prototype #5

July 6, 2020 at 9:11 am Robert Zimmerman Points of Information

Link here. Lots of good information, including details about the growing assembly line of new Raptor engines.

Meanwhile, labeled “27”, the engine – logically assumed to be Raptor SN27 – SpaceX has just installed on Starship SN5 is also of interest. On top of Musk’s recent confirmation that SpaceX is already building Raptor SN30 (probably SN31 or SN32, now), SN27’s assignment to Starship SN5 confirms that the company has managed to complete (and test) at least one next-generation engines every other week since the first full-scale engine shipped to McGregor, Texas in February 2019.

For a brand new engine as complex as Raptor, that’s an impressive production milestone. Per Musk, the end-goal is to produce at least one Raptor per day in the near term – a necessity given that each Starship and Super Heavy booster pair will require at least 37 engines. To feasibly build a fleet of tens – let alone hundreds or thousands – of Starships and boosters, one engine per day is arguably the bare minimum required just for early orbital launch attempts and initial operations.

They hope to start static fire tests, with prototype #5 by July 8th. If these go well they will likely follow soon thereafter with the first short vertical hop.

Israel launches reconnaissance satellite

July 6, 2020 at 8:41 am Robert Zimmerman Points of Information

In its first launch since 2016, Israel yesterday successfully used its Shavit rocket to place a military reconnaissance satellite into orbit.

This was also Israel’s ninth successful launch since it completed its first in 1988. The country has averaged about one launch every four years since, almost of of which have been military reconnaissance satellites. Generally, the pattern has been for Israeli commercial satellites to get launched by other commercial rocket companies, leaving the military launches to Shavit.

The leaders in the 2020 launch race remain unchanged:

15 China

Rocket Lab launch failure

July 4, 2020 at 2:31 pm Robert Zimmerman Points of Information

Electron 34 seconds from launch

UPDATE: Mere seconds after I uploaded the post below, Rocket Lab announced that something had gone wrong late in the launch, resulting in the loss of all seven satellites.

This failure is the company’s second since their first test launch attempt. It will certainly prevent them from their goal this year of monthly launches.

The failure also changes the launch standings below. Rocket Lab is no longer among the leaders, and the U.S. leads China 16 to 14.

The original post:
—————————
Capitalism in space: Rocket Lab today successfully completed the thirteenth launch of its Electron rocket, placing seven smallsats into orbit.

The picture above, captured from their live feed 34 seconds before launch, is most amusing because of the white sheep and black cattle grazing in the foreground.

This launch, three weeks after their previous launch, was their fastest turn-around so far. They made no attempt this time to recover the first stage, but noted that they plan to do so on their seventeenth launch, four launches from now.

LightSail-2 extends mission

July 3, 2020 at 9:37 am Robert Zimmerman Points of Information

Capitalism in space: The Planetary Society’s satellite designed to test the use of a light sail in orbit, LightSail-2, has now begun an extended mission one year after launch.

It appears that they have successfully used the light sail to delay the decay of the satellite’s orbit, as well as change that orbit slightly. The extension will thus allow them to get a better and more exact understanding of the sail’s capabilities, information NASA will use in its own solar sail demonstration mission, NEA Scout, a cubesat that will use a solar sail to fly to an asteroid.

United Kingdom partnership buys bankrupt OneWeb

July 3, 2020 at 9:24 am Robert Zimmerman Points of Information

Capitalism in space? A partnership between the UK government and an Indian company operating in the UK has purchased the bankrupt satellite company OneWeb for $1 billion.

The decision for the U.K. government to purchase OneWeb came with few details about when satellite launches will resume and exactly what the OneWeb satellites will now be used for and even who will have access to them once launched.

The overall deal is worth $1 billion USD, with the U.K. government and Bharti Enterprises Ltd. (an Indian-based company with an operational arm in the U.K.) each committing $500 million USD to the acquisition deal.

The buy-out is expected to close by the end of the year and will represent a 90% overall stake in OneWeb, with the organization’s original investors maintaining a 10% share according to reports from Bloomberg News.

The Johnson government has indicated it wishes to use the OneWeb constellation, still incomplete, as some sort of navigational tool, like GPS. The problem is that the satellites were not designed for this, but for providing internet service.

The article provides a good overview of the questions raised by this government decision. It is hard to figure how this purchase makes sense for the UK government. The impact however on one of OneWeb’s launch providers, Russia, could be very negative. OneWeb was going use a lot of Soyuz rockets to get its satellites off the ground, and had become practically the only commercial customer Russia still has. It is unclear what will happen now with that contract deal.

Arianespace delays Vega launch seven more weeks

July 2, 2020 at 11:24 am Robert Zimmerman Points of Information

Arianespace announced yesterday that it has pushed back its first Vega rocket launch since the spring of 2019 (when the rocket failed) for seven more weeks, until August 17, 2020.

They had been trying to get the rocket off the ground this past week, but had been forced to scub several times because of high winds. They claim this long new delay is to wait until the weather improves, which really doesn’t make sense. Eric Berger at Ars Technica did some digging to find that other scheduling issues, including the odious lock down rules because of the Wuhan panic, were the really reason for the additional seven week delay. They have to recharge the batteries on the rocket, but don’t have time to do it before another launch is set to occur.

This process appears to involve customer representatives flying into French Guiana to perform this task, and there is a mandatory 14-day quarantine upon arrival in the non-European part of France that borders Brazil.

Finally, Arianespace also has a commercial satellite launch mission upcoming on its larger Ariane 5 rocket, and this VA253 flight has been scheduled for July 28. Because there is a minimum of a two-week turnaround time between launches at the spaceport in French Guiana, there was not time to reset the Vega rocket and its payloads before this mission.

With these rules and launch limitations, Arianespace is going to have increasing problems competing with the newer launch companies, all of whom are aiming, like SpaceX, to have almost instantaneous launch turn-arounds.

Defense Department cancels small rocket contract awards

July 2, 2020 at 10:59 am Robert Zimmerman Points of Information

The Department of Defense yesterday withdrew the small contracts it had given to six small rocket companies on June 16 using funds allocated to help companies impacted by the Wuhan flu panic lock downs.

According to multiple industry sources, the selection of the six companies drew widespread criticism because it was unclear how these suppliers were selected over others. When contracts are awarded without an open competition, DoD by law has to file a “Justification & Approval” document explaining why an award was sole-sourced. No J&A documents were filed in this case.

This certainly appears fishy, as there are far more than six startups trying to capture market share in the smallsat launch market. Defense could now allow companies to competitively bid on this money, estimated to be about $115 million total, but it is unclear whether it will.

Blue Origin delivers its first BE-4 rocket engine

July 2, 2020 at 10:42 am Robert Zimmerman Points of Information

Capitalism in space: Blue Origin this week delivered its first BE-4 rocket engine to ULA, for use in ULA’s new Vulcan rocket.

This engine is still a test article and is not yet flight-worthy.

“The engine delivered is the first pathfinder engine to be mated with the Vulcan Centaur and will support ULA’s testing,” a Blue Origin spokesperson told SpaceNews. “We are planning on delivering the second engine in July.” A pathfinder is a development engine. Blue Origin has not said when a flight-qualified engine will be delivered.

…ULA set a 2021 target to fly its first Vulcan Centaur mission and needs two production-quality engines to build the launch vehicle for that mission. Flying Vulcan Centaur in 2021 is an imperative for ULA as it tries to win one of two contracts that the U.S. Space Force will award this summer to launch dozens of national security satellites between 2022 and 2027.

According to sources, frustration has been mounting at ULA as the company’s future is tied to the success of Vulcan Centaur and there is no room for error when it comes to the main engine.

I empathize with ULA’s frustration. The pace of development at Blue Origin has seemed incredibly slow in the past two years. They had begun static fire tests in 2018, and then — beginning with ULA’s decision to buy the BE-4 for Vulcan in May 2018 — for more than a year there was no news. It wasn’t until August 2019 that they announced completion of the first full power test. Even then, it took another whole year before they got to this point now, where they were willing to deliver a first test engine to ULA.

Building a new rocket engine is not simple, so these delays could be entirely reasonable. At the same time, the company’s overall pace in accomplishing anything has been glacial. For example, in the past three years it has repeatedly not delivered on its promises to start flying humans on its New Shepard suborbital capsule. Four months ago, in their most recent promise, they said they would need three more unmanned test flights of New Shepard before they’d put humans on it, and that all those flights (including the manned one) would occur this year. Yet nothing has happened since.

While I truly want Blue Origin to succeed, one must cast a cold eye on what is really happening. If they wish to really compete with SpaceX they have got to pick up their pace.

Boeing’s Starliner aces parachute test

July 1, 2020 at 9:26 am Robert Zimmerman Points of Information

Capitalism in space: Boeing last week successfully completed a Starliner parachute test designed to simulate the return of a capsule after a launch abort.

This is good news for the capsule and Boeing, but I am a bit puzzled why this test, to be followed by a second similar test, was done. These parachutes were supposedly tested thoroughly already, proven, and ready for use for manned missions. Part of that proof was an earlier launch abort test as well as Boeing’s unmanned orbital demo flight that failed to dock with ISS. Both returned to Earth safely using these parachutes. I wonder if during those latter flights they found issues with the parachutes that needed smoothing out by even more tests.

Either way, this success improves the chances that Starliner will finally fly manned early next year, giving the U.S. two different operational manned capsules for getting humans into space.

SpaceX’s reusable first stages and their dramatic impact on the bottom line

July 1, 2020 at 9:15 am Robert Zimmerman Points of Information

This article by Eric Berger at Ars Technica outlining the status of SpaceX’s fleet of reusable first stages contained this incredible fact:

On May 11, 2018, the company launched the first of its new “Block 5” version of its Falcon 9 rocket. This new version of the first stage incorporated all of the company’s previous performance upgrades to the Falcon 9 rocket while also maximizing its reuse. It worked—SpaceX has now flown two different Falcon 9 cores five times, and it may fly a first stage for the sixth time later this summer.

The success of the Block 5 rocket means that SpaceX has had to devote less time and resources to building Falcon 9 first stages. Since May 2018, it has launched 31 times on a Block 5 version of the Falcon 9 rocket—while using just 10 cores. Put another way, reuse has saved SpaceX the cost of 189 Merlin rocket engines, dozens of fuel tanks, and many complex avionics systems. [emphasis mine]

That is a lot of cost savings, which the company is not only using to cut its prices but also to reduce the cost of its Starlink launches. It appears SpaceX wants those launches, as much as possible, to use reused boosters in order to lower the overall cost of getting that internet constellation into orbit. This in turn will make it possible for them to charge less for the service, once they begin offering it.

Russia to consider building reusable stages for Angara

July 1, 2020 at 8:55 am Robert Zimmerman Points of Information

Roscosmos, Russia’s space agency that controls that nation’s entire aerospace industry, is “considering” the idea of developing reusable rocket stages for future iterations of its new Angara rocket.

“On June 30, changes were made to the state contract on the ‘Amur’ experimental design work that envisaged upgrading and further developing this series,” the statement says. In particular, the changes envisage developing the Angara-A5M as the upgraded version of the Angara-A5 rocket and the conceptual design of the Angara-A5V increased lifting capacity vehicle (with the oxygen-hydrogen third stage).

“Also, an option will be considered to develop the Angara-A5VM carrier rocket with reusable stages,” Roscosmos specified.

I’ll believe it when I see it. For now almost twenty years the Russians have been very good at issuing bold press releases promising wonderful new rockets, spaceships, and projects, only to have none of these rockets, spaceships, or projects ever actually happen.

That they are even considering reusable first stages however does show the power of competition and freedom. They never would have if SpaceX hadn’t come along and cut costs with this idea and thus take their entire market share from them. Now they have to find a way to compete in order to get some of that business back..

Starship prototype #5 passes cryogenic test

July 1, 2020 at 8:40 am Robert Zimmerman Points of Information

Capitalism in space: SpaceX’s fifth Starship prototype #5 last night successfully completed a cryogenic test of its tanks, setting the stage for its first vertical test flight.

SpaceX’s Starship SN5 prototype performed a cryogenic proof test at the launch provider’s Boca Chica, Texas facility on Tuesday evening. The test marked a rapid recovery for SpaceX – managing to return to testing a month after the previous vehicle exploded on the pad.

The cryogenic proof is when the vehicle’s propellant tanks are filled with liquid nitrogen and pressurized to flight pressures. Then, hydraulic pistons (otherwise known as a thrust simulator) press against the base of the vehicle to mimic the force of a Raptor engine. The proof test will ensure that Starship SN5 is structurally sound ahead of testing with liquid oxygen and methane. Unlike oxygen and methane, nitrogen is inert and will not combust if something were to go wrong.

The article at the link gives a nice overview of the test program, and what is to come next.

Russia to lower launch price of new Angara rocket

June 29, 2020 at 8:38 am Robert Zimmerman Points of Information

Capitalism in space: According to its 2019 financial report, the Russian manufacturer of that country’s new Angara rocket intends by 2024 to lower launch price from about $100 million to about $57 million.

The high cost price of the latest Angara carrier rocket before the start of its serial production is due to the need for the Khrunichev Space Center to work at two sites, the press office of the State Space Corporation Roscosmos told TASS on Monday. “Before the production process is fully moved to the site of the Polyot company in Omsk, the Khrunichev Space Center has to work at two production sites, which creates additional overhead costs,” a Roscosmos spokesman said.

As part of its trials, the Angara rocket is being produced singly instead of serially, he said. “After the serial full-cycle production is launched, the item’s cost price will decrease,” the spokesman said.

Essentially they are claiming that the cost will drop once they start full production.

Yutu-2 travels 62 feet during 19th lunar day

June 28, 2020 at 10:45 am Robert Zimmerman Points of Information

According to the official Chinese press, Yutu-2 traveled another 62 feet during its 19th lunar day on the far side of the Moon.

I did not get that number from the article, which was written to imply falsely that the rover’s total travel distance since landing (463 meters) was what it did during this single lunar day. To get the real travel distance I took the total from the previously reported total travel distance and figured the difference.

If you want to be educated to the absolutely useless nature of a state-run press, put both links above in separate tabs and compare. You will discover that other than some very minor changes, the new news story is essentially a cut-and-paste of the previous. Which by the way is a cut-and-paste of the last few reports. They don’t even bother to make believe (like the leftist American mainstream media) that they are giving us some information. They simply don’t.

NASA tests SLS backup tank to failure

June 27, 2020 at 6:17 pm Robert Zimmerman Points of Information

In preparation for the only planned full scale static fire engine test of the core first stage of the SLS rocket, NASA engineers have successfully completed a tank test to failure on a back-up oxygen tank.

The tank was filled with water to simulate the oxygen, and cracked as expected at the predicted pressure and at the predicted weld. A short 11-second video of the moment of failure test is embedded below the fold.

This test illustrates the methods by which NASA works. Unlike SpaceX, which is doing similar tests at the very beginning of its Starship design stage to best improve their design, NASA does this testing at the very end of construction, to prove that what they have built will work. The former method in the long run is less risky and faster, as SpaceX quickly finds out what works and doesn’t and builds accordingly.

The latter method is more risky because it depends on complex computer models, which can always be wrong. It also is more expensive in that it requires NASA to build its rockets with large margins of error, just in case those models are wrong. Finally, it appears to take longer to build, because of those required large margins of error. Your rocket or spaceship needs almost to be “gold-plated” to make sure it will work, when completed, since you really can’t test it in the design phase and build it more efficiently based on those tests.

Sierra Nevada starts installing thermal tiles on Tenacity

June 27, 2020 at 6:05 pm Robert Zimmerman Points of Information

Capitalism in space: Sierra Nevada has received and started to install the thermal protection tiles for its first Dream Chaser reusable mini-shuttle, dubbed Tenacity.

The Thermal Protection System (TPS) tiles are one of the major hardware components used on Dream Chaser and cover nearly the entire craft to protect it from the heat of the sun and the plasma regime during atmospheric reentry. The tiles can withstand the scorching heat of 1,650°C (3,000°F) and prevent the vehicle from being destroyed during reentry.

Dream Chaser has approximately 2,000 TPS tile compared to the 24,000 tiles used on the Space Shuttle. Dream Chaser is about 1/4 the size of a Shuttle Orbiter. The tiles on Dream Chaser utilize a room temperature vulcanizing (RTV) silicone to keep the tiles bonded to the vehicle at all times. The silicone can withstand high temperatures, making it ideal for use. Each of the tiles is tested by a mechanism that pulls on each one, helping avoid issues of the tiles falling off, which happened early in the Space Shuttle Program.

The company notes that the vehicle remains on schedule for a 2021 launch on a ULA Vulcan rocket.

UK to bid for purchase of bankrupt OneWeb

June 26, 2020 at 10:59 am Robert Zimmerman Points of Information

Capitalism in space? The United Kingdom appears about to bid $500 million to purchase the bankrupt satellite communications company OneWeb, apparently in an effort to use its satellites as a quick form of GPS-type satellites.

Among the uses being claimed for OneWeb’s technology is that it could be an alternative Galileo, the GPS satellite constellation built by the EU. Britain was kicked out of the project as a result of Brexit. Some have speculated OneWeb might be used as a cheaper alternative.

However, while acquiring such a satellite network would be a coup, industry sources are divided on whether the satellites could be easily retrofitted to perform a role as GPS. GPS technology is also owned by the US, and Washington has been against its allies building rival systems. “The system was built as a communications network,” says one source, questioning how easily it could be changed to GPS.

The article also notes that three Chinese companies are also considering bidding. All these foreign bids (especially the Chinese ones) however face U.S. government review, which will I expect almost certainly reject the Chinese bids.

The deadline for bids is tonight, so we shall find out soon.

Tests of the solar panels and the capsule’s power systems have so far been “better than expected.” Besides these tests, they still have one other major in-orbit test.

On July 4, the space station crew will perform a habitability test with the craft, with four astronauts climbing into the capsule and practicing everyday activities like sleeping, hygiene tasks, as well as emergency procedures to see what it will be like for future crewed missions. On Demo-2, only two astronauts were on board for the trip but regular flights will carry at least four people, so this test will help inform astronauts on those future trips.

Privately-built Japanese smallsat successfully tests new technology

June 26, 2020 at 10:34 am Robert Zimmerman Points of Information

Capitalism in space: A privately-built Japanese smallsat has successfully tested seven new technologies on a six-month long mission that was launched in January on Japan’s newest low-cost Epsilon rocket.

For the first time, the Japanese space agency turned over development of one of its satellites to a startup. Axelspace Co. developed RAPIS-1 for the agency is a short time period, going from design to launch in only about two years, the agency said. The satellite bus features a standardized interface that made attaching instruments and equipment easier. The mission equipment and bus were independently designed to prevent failures of the former from affecting the latter, JAXA said.

The article at the link provides details about the technologies tested, all of which increase significantly the capabilities of smallsats to replace standard larger and heavier satellites.
