UK awards launch license to Cornwall airport

9:31 am

After several months delay, the Civil Aviation Authority (CAA) in the United Kingdom yesterday issued a license to a Cornwall airport, dubbed Spaceport Cornwall, allowing Virgin Orbit to begin final preparations for the first orbital launch from within the British Isles.

The red tape however is not done.

The licence means that Virgin Orbit, which is behind the launch (named Start Me Up after the Rolling Stones song), is clear to begin to carry out mission-readiness tasks. But further licences are needed relating to this specific mission before blast-off can happen.

Melissa Thorpe, the head of Spaceport Cornwall, said: “To be the first spaceport in the UK with a licence to operate is a historic moment. Cornwall is now ready to open up the use of space for good.” She added: “The CAA continues to work on several licence applications, including being in very advanced stages with Virgin Orbit on its applications for launch and range licences, as well as the satellite operators, ahead of a proposed first UK launch.

I am reminded of the meme showing a crowd of officials surrounding one ditch digger, with the only one doing any real work that digger. It appears right now that the bureaucrats in the CAA might outnumber the staffing at both Virgin Orbit and Cornwall, and all they have to do is issue a piece of paper.

NASA awards Starship a second manned lunar landing contract

9:20 am

Capitalism in space: NASA yesterday modified its manned lunar lander contract with SpaceX to award Starship a second manned lunar landing for $1.15 billion.

Known as Option B, the modification follows an award to SpaceX in July 2021 under the Next Space Technologies for Exploration Partnerships-2 (NextSTEP-2) Appendix H Option A contract. NASA previously announced plans to pursue this Option B with SpaceX. The contract modification has a value of about $1.15 billion.

…The aim of this new work under Option B is to develop and demonstrate a Starship lunar lander that meets NASA’s sustaining requirements for missions beyond Artemis III, including docking with Gateway, accommodating four crew members, and delivering more mass to the surface.

NASA is also accepting bids for a competitive second manned lunar lander, but has awarded nothing as yet.

Combined with earlier investments and contracts, SpaceX now had garnered about $13 billion for developing Starship and Starlink, about $9 billion from private investment capital and about $4 billion from NASA, with most of the cash used for Starship. In addition, the company plans another investment funding round that will raise its valuation to $150 billion.

SLS might have flown once, but it appears both NASA and the investment community is increasingly putting its eggs in the Starship basket.

Chinese pseudo-company Galactic Energy launches five satellites into orbit

9:09 am

The Chinese pseudo-company Galactic Energy today used its Ceres-1 rocket to put five Earth observations satellites into orbit.

According to China’s state run press, Ceres-1 is a “small-scale solid-propellant carrier rocket capable of sending micro-satellites into low-Earth orbit.” In other words, it was developed initially by the military for missile use, and the government has allowed it to be upgraded for civilian use.

The leaders in the 2022 launch race:

52 SpaceX
52 China
19 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 76 to 52 in the national rankings, but trails the rest of the world combined 80 to 76.

The 52 launches by China ties its yearly record, set last year, for the most successful launches in a single year. Like the U.S. China appears set to smash its launch record in 2022.

The lunar surface is arid

8:10 am

The uncertainty of science: According to a paper published at the end of October, scientists have used data from the LADEE lunar orbiter (that circled the Moon in 2013-2014) and found that the surface of the Moon is extremely arid, and if there is any ice trapped in the permanently shadowed craters at the poles it did not come from meteorite impacts elsewhere on the Moon. From the abstract:

The upper bound for exospheric water derived here from data collected in 2013–2014 by the neutral mass spectrometer on the Lunar Atmosphere and Dust Environment Explorer spacecraft [LADEE], about three molecules/cc, pales in comparison to the concentration of ∼15,000 molecules/cc needed to sequester the meteoritic water influx. The only pragmatic conclusion is that the hypothesis for water ice accumulation at the poles due to exospheric transport is false.

The theory had been that any water from these meteorites could have been transported by various processes to the polar cold traps. This data says that did not happen, and if there is water ice in the polar cold traps, its origin remains unknown, though comet impacts at the poles might have been a source.

This result also appears to contradict other orbital data that has suggested there is some water in the lunar regolith at mid and low latitudes.

NASA’s SLS rocket successfully launches Orion toward the Moon

12:26 am

After almost eighteen years of development and almost sixty billion dollars, NASA tonight finally completed the first unmanned test launch of its Space Launch System (SLS) rocket, lifting off at 1:41 am (Eastern).

The two solid rocket boosters functioned as planned, separating from the core stage with no problem. Then core stage and its four former shuttle engines completed its burn, putting the capsule and its upper stage into Earth orbit, and then separated cleanly. At about 30 minutes after launch the service module’s solar arrays completed their deployment. At 53 minutes after launch a 30 second burn circularized the orbit in preparation for the trans-lunar-injection (TLI) burn that will send Orion to the Moon. TLI occurred about 90 minutes after launch, after a period of check-out in orbit.

Orion will spend 26 days in space, about a week of which will be in a wide lunar orbit, testing its systems. If all goes right it will splashdown on around December 11th.

As this was the first U.S. government launch in more than a decade, since 2011 when the space shuttle was retired, the leader board for the 2022 launch race remains unchanged:

The leaders in the 2022 launch race:

52 SpaceX
51 China
19 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 76 to 51 in the national rankings, and trails the rest of the world combined 79 to 76.

Martian helicopters of the future

10:08 am

Today Bob Balaram, the chief engineer for the Mars helicopter Ingenuity, wrote up a short essay summarizing the helicopter’s successes on Mars.

This aircraft, very much also a spacecraft, has been on its own on the surface of Mars, detached from its traveling companion Perseverance, for over 500 Martian days or sols. It has operated way beyond its original planned mission of 30 sols, including surviving a brutal winter that it was not designed for. With 33 flights, almost an hour of flight time, over 7 km of travel in Jezero crater, takeoffs and landings from 25 airfields, almost 4000 navigation camera images, and 200 high-resolution color images, it has proven its worth as a scout for both scientists and rover planners. Currently, it is getting ready to use its fourth software update – this one with advanced navigation capabilities that will allow it to safely fly up the steep terrain of the Jezero river delta, scouting ahead of the rover Perseverance as it searches for signs of past life on Mars. [emphasis mine]

I have highlighted the number of flights above because Ingenuity was supposed to do a very short 34th flight on November 10th that would only have the helicopter go straight up 16 feet, hover, and then come straight back down. Yet, I have seen no postflight reports, and Ingenuity’s flight log still does not include it as of today. One image from Ingenuity that was taken on November 9th has been released, and shows the ground directly below it. No other recent images of this 34th flight however have been released.

The flight could still have happened, or was scrubbed for a later time. What is important however is all those other 33 flights, and what Ingenuity’s overall success has meant for future Martian exploration. As Balaram writes,

Watching the first SLS launch tonight

9:25 am

At this moment, with weather 90% favorable and the countdown underway, the first launch of NASA’s SLS rocket appears go for a 1:04 AM (Eastern) launch tonight.

You can watch the live stream on NASA TV here, which will begin at 3:30 pm today and mostly be NASA propaganda intermixed with descriptions of the rocket, its payloads, its full mission, and updates on the launch countdown.

NASA’s live stream is now embedded below, beginning at 10:30 PM (Eastern) when actual coverage of the final countdown begins. I would still suggest that you wait until at least 12:30 AM (Eastern) before watching, as those first two hours will still be filled with a lot of NASA propaganda blather.

Superheavy prototype #7 undergoes 14 engine static fire test

9:16 am

SpaceX’s seventh prototype of its Superheavy first stage booster — intended to launch its Starship orbital craft on the first orbital flight — successfully completed a 10-second static fire test of 14 of its 33 engines yesterday.

I have embedded video of the test below the fold. It shows the burn repeatedly from different angles. It appears the engine test went exactly as planned, with no subsequent fires near the launch pad.

According to the article at the link, this test fire, even with only 14 engines, made this Superheavy booster the most powerful rocket on Earth, at least until tonight when NASA’s SLS launches. Once this booster fires all of its 33 Raptor-2 engines however it will then exceed SLS in power. That it hasn’t launched however makes this claim a little overstated.

Regardless, SpaceX continues to move quite smoothly towards that first orbital launch of Starship, which the company hopes to do before the end of the year.

ABL scrubs first launch attempt

9:02 am

The rocket startup ABL yesterday scrubbed its first attempt to launch its new RS1 smallsat rocket from Alaska, due to “off-nominal data on the first stage during propellant loading.”

This test launch carries two cubesats for a customer, but its prime mission is to demonstrate the rocket’s ability to put those smallsats into orbit.

The company is trying again today, but is providing no live stream of the countdown or launch. We can only wait for updates.

NASA managers okay SLS launch attempt November 16th

7:39 pm

NASA managers have given the go-ahead to the scheduled launch of the agency’s SLS rocket for 1:04 am (Eastern) on November 16, 2022, despite the existence of some detached caulking that Hurricane Nicole had pulled free.

Engineers examined detailed analysis of caulk on a seam between an ogive on Orion’s launch abort system and the crew module adapter and potential risks if it were to detach during launch. The mission management team determined there is a low likelihood that if additional material tears off it would pose a critical risk to the flight.

Technicians also completed replacing a component of an electrical connector on the hydrogen tail service mast umbilical. While swapping the component did not fully fix the issue, engineers have redundant sources of information supplied through the connector.

The launch window is two hours long. As this is a night launch, it will be quite spectacular, no matter what happens. I will embed the live stream tomorrow in the early evening, for those who wish to watch NASA’s multi-hour propaganda stream. My suggestion would be to find a better use of your time until around 12:50 am (Eastern). Then would be a good time to tune in.

Spire offers way to track ships even when they are trying to hide

12:44 pm

The smallsat company Spire is now offering what it calls its ‘Dark Shipping’ and ‘Spoofing’ Detection” option, using its 100-satellite constellation to track ships even when they are trying to hide.

Spire says the new dark shipping detection solution taps into the company’s constellation of more than 100 satellites to provide near real-time global AIS [Automatic Identification System] message position validation to uncover suspicious activity and pinpoint a vessel without the need for an approximate location.

“For a long time, having the tools to accurately identify and track ships that are attempting to hide their activities or location has been the missing key to preventing sanctions evasion, illegal fishing, human trafficking and many more pressing societal issues,” said Peter Mabson, CEO, Spire Maritime.

Hat tip to Robert Pratt of Pratt on Texas, who emailed me this press release and noted that this was “just one example of how lower launch costs are driving new things most would not guess.”

To me, this is both good and bad. Spire’s tracking capability gets it another way to make money as well as to track illegal activity. It also allows governments another way to track everyone to keep them from doing anything the authorities dislike.

When we had a government that saw itself as the servant to the people, I would not be so worried about the latter. With our present corrupt government, misuse of this information by those in power is now a real concern.
