ULA pinpoints cause of Delta launch abort, reschedules launch

2:58 pm

ULA has identified the cause of the launch abort of its Delta 4 Heavy rocket on August 29th, and has now aiming for a launch no earlier than September 18th.

A torn diaphragm in one of three pressure regulators at Cape Canaveral Air Force Station’s Launch Complex 37 caused the computer-controlled scrub just three seconds before liftoff on Aug. 29, ULA CEO Tory Bruno said via Twitter on Wednesday. The engines briefly lit on fire, but the rocket remained firmly on the pad.

“Torn diaphragm (in the regulator), which can occur over time,” Bruno said. “Verifying the condition of the other two regulators. We will replace or rebuild as needed, re-test, and then resume towards launch.” [emphasis mine]

The highlighted words illustrate the less than stellar old space rocket design that the Delta 4 Heavy represents, and that ULA is perpetuating as long as it uses this rocket. Rather than redesign so that these torn diaphragms will no longer be a problem, it appears they will simply make sure this design is tested and works, for this launch. Thus, this issue has the possibility of reappearing in a future launch.

Wouldn’t it be better to upgrade and eliminate such a problem, for good, once it is identified? That appears to be SpaceX’s strategy, and the consequence is that their rockets and spacecraft get increasingly more reliable with time.

Anyway, if ULA’s schedule holds, it means there will be two launches at Cape Canaveral in less than 24 hours, as SpaceX is aiming for another Starlink launch the day earlier.

Northrop Grumman shuts down Omega rocket program

2:49 pm

Having lost any chance of getting launch contracts or development money from the military for the next five-plus years, Northrop Grumman has chosen to shut down its Omega rocket program.

“We have chosen not to continue development of the OmegA launch system at this time,” Northrop Grumman spokeswoman Jennifer Bowman said in a statement. “We look forward to continuing to play a key role in National Security Space Launch missions and leveraging our OmegA investments in other activities across our business.”

Bowman said the company will not be protesting the U.S. Space Force’s decision to select United Launch Alliance and SpaceX for the NSSL contracts.

This was a typical big space Washington project, aimed solely at getting government contracts, as well as government cash to develop it. The company had no interest in trying to develop it with its own R&D funds in order to garner market share in the general launch market, or even to make it cheaper and more useful to the military than SpaceX’s rocket.

In this sense this is no great loss. What we need is real competition, aimed at coming up with better ideas that will lower cost and increase capabilities. What Northrop Grumman was offering was none of those things. It was fake competition, and of no real value.

NASA solicits lunar landers to bid on bringing science instruments to Moon

8:56 am

UPDATE: It appears I misunderstood the nature of this NASA solicitation in my initial post. I have rewritten it to correct it. Hat tip reader Rex Ridenoure.

Capitalism in space: NASA has issued a request from the private companies building unmanned lunar landers to bid on carrying a variety of science instruments to the Moon by ’23.

Initially NASA had indicated it was farming out the design and construction of the lunar landers to private companies, but would have the science instruments designed and built in-house. Since ’19 however NASA has had private companies designing and building these fourteen small science payloads, and is now in the process of determining which private landers will bring them to the Moon.

Though this approach is not very different than past NASA arrangements, what is different is NASA’s public approach. Instead of touting NASA’s part in this work, the agency is touting the work of the private companies.

Russia wins spacesuit contract for India’s Gaganyaan manned mission

9:29 am

The new colonial movement: The Russian Zvezda design center in Roscosmos has won the spacesuit contract to build the spacesuits and capsule seats for India’s Gaganyaan manned mission, targeted for a ’22 launch.

It is not surprising that the Russians won this contract. India does not have a lot of time to get the mission off the ground, and needs help. The Russian spacesuits are practical and proven, and are far superior to anything available from NASA. The only other option available at this moment would be the flight suits SpaceX designed for its Dragon missions and flown once. I suspect the Indians want something that has been used and tested more.

Moreover, their astronauts are being trained by the Russians. Better and simpler to have them use the suits the Russians use.

India sets early 2021 for launch of lunar lander/rover

9:14 am

The new colonial movement: Chandrayaan-3, India’s second attempt to put a lander/rover near the south pole of the Moon, has been rescheduled for launch in early 2021, delayed approximately six months due to the Wuhan flu panic.

The mission has been delayed by the coronavirus pandemic and the follow-up lockdowns. The launch which was planned for 2020 will now take off for the Lunar surface sometime in early 2021.

Chandrayaan-3 will be a mission repeat of Chandrayaan-2 and will include a Lander and Rover similar to that of Chandrayaan-2, but will not have an orbiter, a statement quoting Singh said. Planned to land on the South Pole of the Moon, Chandrayaan-2 was launched on July 22 last year. However, the lander Vikram hard-landed on September 7, crashing India’s dream to become the first nation to successfully touch down on the lunar surface in its maiden attempt.

The orbiter of the mission is working fine and has been sending data, ISRO had indicated that the third moon mission will utilise the orbiter already in the lunar orbit.

India has literally ceased all launches in 2020, since the arrival of the coronavirus. Moreover, though four launches are listed as targeting September launches, none yet have launch dates. It seems that the fear and terror of COVID-19 has caused India’s large space bureaucracy to shut down, even as I am sure they continue to receive their paychecks.

China launches another remote sensing satellite; crashes 1st stage near homes

8:54 am

The new colonial movement: China today used its Long March 4D rocket to launch another remote sensing satellite.

UPDATE: It appears the first stage booster crashed near a populated area. Footage of the crash can be seen here. Note that the red smoke indicates very toxic materials. Anyone who goes close risks serious health problems.

The leaders in the 2020 launch race:

22 China
15 SpaceX

China successfully lands its reusable version of the X-37B

10:33 am

The new colonial movement: After only two days in space, China today successfully landed what appears to be its reusable version of the X-37B.

No photos of this spacecraft have been released, nor has China provided any specific information about its shape or design. What we know however suggests it is similar in concept to the unmanned, pick-up-truck-sized X-37B.

Apparently this short flight was to test its ability to reach orbit and then return autonomously. According to the state-controlled Chinese press, it did so.

Rocket Lab reveals it also launched its own satellite on August 30th

9:16 am

Capitalism in space: Rocket Lab today revealed that along with placing a customer’s commercial radar satellite into orbit on August 30th, it also launched the prototype of its own satellite during the Electron rocket launch.

The company calls its satellites Photons, but rather than number them it will give each their own name. This particular satellite has been dubbed “First Light.”

The satellite is primarily a technology demonstrator, a way to test Photon’s systems in orbit and show customers what the spacecraft is capable of. First Light will stay up for the next five or six years, if all goes according to plan, Rocket Lab founder and CEO Peter Beck said during a teleconference with reporters today (Sept. 3).

Photon should be attractive to a variety of customers, allowing them to focus on their sensors and other instruments without having to worry about building and operating an entire spacecraft, Rocket Lab representatives have said.

The goal is to offer this smallsat as a platform to those who wish to launch an instrument into space but don’t want to spend the money building the satellite itself. The company also intends to use a Photon satellite for a science mission to Venus in 2023.

China launches its version of X-37B

9:05 am

The new colonial movement: It appears that China has launched its version of a reusable X-37B mini-shuttle, or at least, that is most likely first guess, based on the meager data available.

China launched a new experimental reusable space vehicle on Thursday from the Jiuquan Satellite Launch Center using a Long March-2F/T – Chang Zheng-2F/T – launch vehicle. Launch from the LC43/91 launch complex, under a veil of secrecy with no official launch photos or even a launch time disclosed.

Chinese media emitted a laconic report referring, that “the test spacecraft will be in orbit for a period of time before returning to the domestic scheduled landing site. During this period, it will carry out reusable technology verification as planned to provide technical support for the peaceful use of space.”

More at the link, though the lack of information, especially the refusal to even give a launch time, strongly indicates China wants to limit knowledge of this spacecraft’s position in space, thus limiting the ability of others to photograph it. What is known however does point to this being a variation of a small reusable unmanned shuttle, like the X-37B.

While once again China has not come up with something new, copying (or stealing) the idea from someone else, having such a vehicle gives them a significant capability. They can now test many different technologies in orbit for long periods, and get them back to Earth for study afterward.

The leaders in the 2020 launch race:

21 China
15 SpaceX
9 Russia
4 ULA
4 Europe (Arianespace)

The U.S. continues to lead China 24 to 21 in the national rankings.

Another successful Starship prototype hop

11:15 am

Starship prototype #6 in flight

Capitalism in space: SpaceX today successfully completed a 150-meter high hop of its sixth Starship prototype, the second such hop but the first for this prototype. They have now flown two different prototypes, plus Starhopper, all successfully. No flight failures, so far.

Next they will be doing a pressure tank test, to failure, of the seventh prototype. That prototype is using what they think will be a better steel alloy, and they want to find out its limits. I have also heard that they will either fly this prototype again or fly the fifth again, sometime in the next two weeks.

I have embedded a few more images below the fold.

FAA issues Wallops Island launch license to Rocket Lab

9:21 am

Capitalism in space: The FAA has now issued a five year launch license to the smallsat rocket company Rocket Lab, allowing them to launch their Electron rocket from the company’s launch site on Wallops Island, Virginia.

The Launch Operator License allows for multiple launches of the Electron launch vehicle from Rocket Lab Launch Complex 2, eliminating the need to obtain individual, launch-specific licenses for every mission and helping to streamline the path to orbit and enable responsive space access from U.S. soil.

The company hopes to do its first launch from the U.S. before the year is out. It will then have two spaceports, allowing it to double its launch rate.

SpaceX successfully launches Argentina satellite

4:37 pm

Capitalism in space: SpaceX tonight successfully launched an Argentinian radar satellite into polar orbit, the first such launch from Cape Canaveral since the 1960s.

The company also successfully landed the first stage at the Cape, completing that stage’s fourth flight. As I write this they still have two more smallsats to deploy, but it is very unlikely they will have an issue doing so.

The leaders in the 2020 launch race:

20 China
14 SpaceX
9 Russia
4 ULA

The U.S. now leads China 22 to 20 in the national rankings. With a scheduled launch by Rocket Lab from New Zealand later tonight, these numbers could change again before the day is out.

SpaceX scrubs Starship prototype hop

3:32 pm

Capitalism in space: Though it appeared twice today that SpaceX engineers were on the verge of executing their second Starship prototype hop, the first for prototype #6, in both cases they stood down.

It appears according to road closures in Boca Chica they will try again tomorrow. The live stream is available here. The closures go from 8 am to 8 pm (Central), within which the hop could occur at almost any time, but likely not before 9 am.

Confirmed: SpaceX plans two launches for tomorrow

1:02 pm

Capitalism in space: SpaceX has now confirmed that it will attempt two Falcon 9 launches tomorrow at its launch facility at Cape Canaveral, the first to launch 60 Starlink satellites at 10:12 am (Eastern) and the second to launch an Argentinian radar satellite at 7:18 pm (Eastern).

In the first launch the first stage, used once before, will attempt to land on the drone ship in the Atlantic. On the second launch the first stage, used three times previously, will return to Cape Canaveral for its landing attempt.

The live stream for both will be available here.

SpaceX will also tomorrow attempt a 500 meter hop of its sixth Starship prototype. The live stream of that can be seen here.

Meanwhile Rocket Lab has shifted its launch this weekend in New Zealand from tonight to tomorrow night at 11:05 pm (Eastern). The live stream will be aired here.

That means on August 30, 2020 there could be three American launches as well as another test flight of a new reusable rocket.

Note: Astra has delayed the first orbital test flight of its rocket to no early than September 10th due to poor weather in Kodiak, Alaska.

ULA’s Delta 4 Heavy: Launch abort at T-3 seconds tonight

1:14 am

Delta 4 Heavy immediately after engine shutdown

UPDATE: It appears ULA will need at least a week to analyze the situation before attempting another launch. It also appears that SpaceX is going forward with its two launches on August 30.

—————————
Tonight’s attempt by ULA to launch a National Reconnaissance Satellite on its Delta 4 Heavy rocket was aborted at T-3 seconds when the rocket’s main engines did an automatic abort. The image to the right shows the rocket immediately after the engines shut down, the smoke clearing and the rocket still sitting on the launch pad.

They are presently unfueling the rocket and will not launch tonight. They have not set a new launch date, and there is also no word on whether this launch delay will force delays in the two SpaceX launches set for August 30th. My guess is that the issue tonight will take time to assess, so they will give up their place in line and let SpaceX proceed as planned.

In watching ULA’s broadcast tonight, as well as reviewing the issues that prevented launch two days ago, I was struck by several things. First, ULA’s promo films to tout the wonders of the Delta family of rockets actually made them seem incredibly clunky and complex. There seemed to be too many pieces and complex operations to get the rocket ready for launch, which makes sense as Delta rockets are very costly and not competitive with today’s market. This is the exact reason ULA is in the process of retiring the entire Delta family. They will complete the already purchased and scheduled launches, but in the future will use their new Vulcan rocket for similar future bids.

Second, the number of minor and major technical issues during both countdowns reinforced my impressions above. This is a very complex rocket to launch, and that complexity apparently leads to many issues that make launch difficult.

For the scrub on August 26 they first had two blown fuses in a launchpad heater that had to be replaced, then a pneumatics system issue that was apparently not solved during the countdown. When they scrubbed, however, they said they did it because of “several problems,” not just this one.

On tonight’s launch they first had an issue with a fuel valve, then several fuel sensor alarms gave them problems, requiring them to disable them to proceed, then the temperatures in the payload electronics posed an issue that after some analysis was considered acceptable. These issues caused the launch to be delayed by about an hour and a half.

Finally, the rocket’s main engines shut down at the rescheduled lift-off time.

It might not be fair, but in comparing this ULA launch effort with the numerous countdowns by SpaceX the differences were stark. SpaceX has had comparable few issues during recent launches, with only one launch recently scrubbed due to a technical issue in July. Moreover, the company’s launch team has several times had similar launch aborts at T-0, and still were able to recycle everything and proceed to launch immediately.

All these impressions once again suggest that ULA is making the right decision to retire Delta. That it is going to take them several more years however to launch several more government surveillance satellites raises questions about the decisions of our government to pay for such a unwieldy and expensive rocket. There now are better and cheaper options available.

SpaceX wins launch contract for unmanned lunar lander

11:24 am

Capitalism in space: Masten Space Systems has awarded SpaceX the launch contract for its unmanned lunar lander, being built to carry nine NASA science payloads to the south pole of the Moon.

Launch is tentatively scheduled for late ’22.

NASA will be an anchor customer for the mission but Masten intends to sign up others. “There is a tremendous amount of interest,” he said, including from both the public and private sector, although he didn’t mention any specific potential customers.

Mahoney said the level of customer interest soared after Masten won the CLPS award and had a firm schedule for the mission. “Once the CLPS award was made and we crossed from speculative to having a schedule, the tenor and tone of our conversations have changed dramatically.”

The limiting factor for the lander mission has not been the amount of mass available for payloads, he said, but instead positions on the lander that have views of the surface desired by payloads. “There’s a game of positioning among the various instruments so that they can get the view angles that they need and not interfere,” he said.

However, he said the company isn’t considering major changes in the lander’s design to accommodate payloads. “The design principle is the ‘pickup truck’ that can haul a bunch of different things,” he said. “We’re trying to escape the completely unique, bespoke system that does one job and one mission really well.”

I guarantee that at least one university student-built payload will end up on the lander.

FCC approves expansion of OneWeb constellation to 2,000 satellites

11:19 am

Capitalism in space: The FCC has approved the request by the satellite company OneWeb to increase the size of its satellite constellation from 720 to 2,000 satellites, at 50% of which must be launched by August ’26.

The company, now exiting bankruptcy with its purchase by a partnership of the UK government and an Indian-based communications company, appears gearing up to resume launches.

The FCC’s approval was partly because it would “increase competition for broadband services.” Under the Trump administration the goal is to encourage as many private space companies as possible, to promote innovation and the lowering of costs to the consumer. This decision continues that policy.

Five American launches in two days!

9:51 am

Capitalism in space: Though the first launches in the string of four American launches that was initially scheduled to begin two days ago and continue through the weekend was delayed because of weather and then technical issues, all these delays have done is pack those scheduled launches into a shorter time period, with the addition of a fifth launch!

If all goes as scheduled (hardly guaranteed), we will see five launches from three spaceports and four private companies in less than two days. The schedule, as of this moment:

August 29th at 2:04 am (Eastern): ULA’s Delta 4 Heavy to launch a military reconnaissance satellite from Cape Canaveral. The company’s webcast of the launch can be seen here.

August 29th at 11:05 pm (Eastern): Rocket Lab’s Electron rocket will launch a commercial radar satellite from New Zealand. The launch can be watched at the company’s live stream channel.

August 30th at 10:08 am (Eastern): SpaceX’s Falcon 9 will launch more of its Starlink satellites from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 7:19 pm (Eastern): SpaceX’s Falcon 9 will launch an Argentinian Earth observation satellite from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 10:00 pm (Eastern): Astra will attempt the first orbital test launch of its privately built rocket from Kodiak, Alaska. They will not be live streaming their launch, but will provide updates at their Twitter feed.

All times and dates list only the beginning of the launch windows, which means they might launch, but not exactly at the times listed.

Also, SpaceX is aiming to do its second Starship test hop this weekend, the first for its sixth prototype.

Canada proposes new global treaty to control mining in space

10:05 am

The globalists at the UN fight back! A Canada-led effort, endorsed by more than 140 academics, politicians, and diplomats, has proposed that the UN and international community create a new treaty to control mining in space.

Signatories to the request for the UN to intervene believe space must be regulated internationally – similarly to Antarctica or the world’s seabeds – and all countries, including non-space-faring ones, get a say in decision-making. The alternative, they warn, could be a splintered approach where companies conduct flag-of-convenience resource extraction in space under whichever country has the least onerous rules. [emphasis mine]

The Trump administration has made it clear that it wants the ability to establish U.S. law on its space operations, both in spacecraft and on its future bases on the Moon and elsewhere, an ability that the Outer Space Treaty forbids. To get around the treaty, the administration has created what it calls the Artemis Accords. The accords require that any nation that wishes to partner in the American-led Artemis program to explore and colonize the Moon must agree to support the establishment of private enterprise and ownership, with the laws of each nation applied to its own operations. To do this the Trump administration is negotiating individual bi-lateral agreements with its Artemis partners.

In essence, the U.S. is using the strategy of dividing and conquering to overcome the Outer Space Treaty’s restrictions.

Canada’s effort is designed to counter the U.S. approach, which is a strong sign that the Trump effort is working. I suspect the battle-lines are now being drawn between China and the many nations that are not operating in space (note the highlighted text), and the U.S. and those space-faring capitalistic nations that wish to partner with it, such as India and the European Space Agency. In fact, Japan and the U.S. today announced continuing negotiations leading to an agreement endorsing their partnership in Artemis, including the Artemis Accords.

Where Russia stands in this battle remains uncertain. They desperately need to partner with someone in the new effort to get to the Moon, since they no longer have the economic resources to do it themselves. The U.S. has made it clear they could join Artemis, but the Putin government opposes the Artemis Accords, preferring that the international community (meaning governments such as them) retain ownership over space resources. They have begun negotiations to partner with China, but it is unclear how much China wishes to partner with anyone.

Regardless, it would be terrible blow to freedom and private enterprise for the U.S. to agree to this Canadian-led effort. Should that approach win, it would make provide ownership and capitalism in space impossible. All power and control will devolve to the global international community, which will then dictate that nothing can happen but what it wants. For example, all the many nations incapable of doing anything in space will want a piece of the action from those nations and companies that are capable, and the result will be that no one will do anything because it simply will not be profitable. Space will simply become another failed communist state, dying before it even becomes born.

Delta 4 Heavy launch scrubbed

11:15 pm

Tonight’s launch of ULA’s Delta 4 Heavy was scrubbed due to a variety of technical problems. They have not set a new launch time, though they say they are aiming for the early morning hours of August 28.

This was to have been the first of four American launches in the next four days. The next, a Falcon 9 launch of an Argentinian radar Earth observation satellite, was scheduled for tomorrow, August 27th, at 7:19 pm (Eastern). No word on whether it is going forward as planned, though it might be since the ULA launch has shifted after it, to August 28th.

The third, by Rocket Lab, is presently scheduled also for August 28rd at 11:05 pm (Eastern), launching out of New Zealand.

The fourth, another SpaceX launch of more Starlink satellites, had been scheduled for 10:30 am (Eastern) on August 29th. Once again, this schedule could change due to tonight’s ULA scrub.

Stay tuned. I suspect all three companies are going to aggressively work to get all four launches off as fast as possible, even if not exactly as presently scheduled.

The view from the cockpit

6:01 pm

An evening pause: This short video shows us what it is like for the pilot and co-pilot as they prepare for departure from Frankfurt, Germany, on a cargo flight to Africa and beyond. Note that even though the crew is German and the airport is German, all communications with the control tower are in English. Note also that their altitude is recorded in feet, not meters. The American big lead in the commercial airline industry in the first half of the 20th century allowed it to set the standards, including the use of feet and English in these matters.

NASA/Boeing set summer ’21 for first manned Starliner mission

4:00 pm

Capitalism in space: NASA and Boeing have tentatively scheduled the launch of the first manned Starliner mission to ISS for the summer of 2021.

Boeing Co said on Tuesday it aims to redo its unmanned Starliner crew capsule flight test to the International Space Station (ISS) in December or January, depending on when it completes software and test hardware production development.

If the test mission is successful, Boeing and NASA will fly Starliner’s first crewed mission in summer 2021, with a post-certification mission roughly scheduled for the following winter, the company added.

Everything of course depends on the success of the unmanned demo flight. If the capsule has any further problems, as it did on its first unmanned demo flight, the manned flight will likely be delayed again.

Virgin Galactic searching for profits outside of space tourism

7:52 am

Not a surprise: After almost two decades of development and no commercial suborbital tourism flights, the new management of Virgin Galactic (with Richard Branson having sold off his majority shares) is now searching for other ways to make money with its assets.

Among them, renting out the WhiteKnightTwo (WK2) launch support aircraft for government or private businesses to use for science, research, and national security applications. There’s just one problem: Legally it cannot do that.

Because WhiteKnightTwo is considered an experimental aircraft by the Federal Aviation Administration using it in this manner would be a violation of 14 CFR 91.319(a)(2), which states that “no person may operate an aircraft that has an experimental certificate – (1) For other than the purpose for which the certificate was issued; or (2) Carrying persons or property for compensation or hire.” In a filing made Tuesday The Space Company and Virgin Galactic jointly petitioned for exemption from the regulations.

It appears the new management is recognizing that the suborbital tourism market is weak (with the coming of orbital tourism), and needs to shift gears, any way it can.

Report: Astronomy threatened by satellite constellations

11:31 am

A report issued today, resulting from a video conference of astronomers in July, has concluded that much of ground-based astronomy is threatened by the new large satellite constellations being launched by SpaceX, OneWeb, and others.

The astronomers’ report offers six solutions for solving the problem.

  • Launch fewer or no LEOsats. However impractical or unlikely, this is the only option identified that can achieve zero astronomical impact.
  • Deploy satellites at orbital altitudes no higher than ~600 km.
  • Darken satellites or use sunshades to shadow their reflective surfaces.
  • Control each satellite’s orientation in space to reflect less sunlight to Earth.
  • Minimize or eventually be able to eliminate the effect of satellite trails during the processing of astronomical images.
  • Make more accurate orbital information available for satellites so that observers can avoid pointing telescopes at them.

Notice what solution they don’t offer? Maybe astronomy should focus on building space-based telescopes, where the view would be clear, unimpeded by both the satellites and (much more importantly) the atmosphere.

In fact, the claim in the first solution above, that launching no satellites is “the only option identified that can achieve zero astronomical impact” is intellectually dishonest. All astronomers have to do is get their observatories into space, something that is very doable and affordable with today’s cheaper launch capabilities and technology. In space the impact of the satellites will once again be zero. And they will have the added benefit of getting outside the atmosphere, which by the way is actually a bigger limitation to observations than any satellite constellation.

It seems to me that this report was written by the faction of astronomers who make their living building big ground-based telescopes. Rather than think of solutions, they want to protect their turf by attacking the achievements of others.
