SpaceX launches another 60 Starlink satellites

10:18 am

Capitalism in space: SpaceX today successfully launched another 60 Starlink satellites, raising the constellation to more than 800 satellites.

The first stage successfully landed, for the sixth time, on a drone ship. The company also recovered both fairings, which were making their third flight. With one fairing’s recovery however the net broke on the ship, which might have damaged it this time.

The leaders in the 2020 launch race:

26 China
17 SpaceX
11 Russia
4 ULA
4 Europe (Arianespace)

The U.S. had regained the lead over China, 27 to 26, in the national rankings.

Another high altitude balloon company enters the space tourism market

3:30 pm

Capitalism in space: Another high altitude balloon company, this time from Spain, is now vying for the space tourism market.

EOS-X Space, a Spanish startup, wants to take 10,000 people to the frontier of space within the next 10 years. With EOS-X Space, the journeys won’t be in rockets or ultrasonic planes. They’ll instead take place in a pressurized capsule propelled by a balloon that will rise to an altitude of up to 40 kilometers, or nearly 25 miles.

This means space tourists won’t have to wear a suit for the duration of the trip, nor will they have to do any physical preparation. Depending on the weather, each trip is set to last four or five hours.

They are targeting the same market as the American company Space Perspectives, which hopes to begin flying tourists on its stratospheric balloon, dubbed Neptune, by ’24.

Spaceport America in New Mexico fires its head

3:26 pm

The board of Spaceport America, Virgin Galactic’s launchsite for its SpaceShipTwo suborbital manned spacecraft, yesterday fired its long time Executive Directory Dan Hicks, at the same time governor of New Mexico removed one board member.

Hicks, the spaceport’s CEO since 2016, has been on administrative leave since June while allegations of mismanagement and abuse of authority have been under investigation by the New Mexico State Auditor and the New Mexico Spaceport Authority, the public body governing the spaceport.

The McHard Accounting Consulting firm, a forensic accounting firm based in Albuquerque, conducted an investigation which was then referred to the state auditor. Keyes informed a state legislative committee this summer the allegations included potential criminal activity.

Spaceport American had been made gigantic promises by Richard Branson back in the mid-2000s, including hundreds of tourist flights per year on SpaceShipTwo, all of which would bring lots of cash to the spaceport and to New Mexico. All came to naught. I suspect those failed promises are somehow connected to the accusations here.

Delta 4 Heavy launch now delayed indefinitely due to launchpad issues

3:16 pm

ULA has now delayed indefinitely the launch of a military reconnaissance satellite using its Delta 4 Heavy rocket because of ongoing issues in the swing arms on the launch tower.

According to ULA’s CEO, Tory Bruno:

..ULA was “working through an issue with pad hydraulics” associated with the swing arm retraction system at the Delta 4 launch pad. Three swing arms feeding propellants and conditioned air to the rocket and its satellite payload are designed to retract as the Delta 4-Heavy lifts off.

“Fixing is always easy,” Bruno tweeted. “Making sure something stays fixed takes more work and lots of discipline.”

This launch has been delayed numerous times in the past two months, almost always because of a variety of different problems, most related to the launchpad, with two scrubs occurring as launch aborts at launch. As the article at the link correctly notes,

The repeated problems with different parts of the Delta 4-Heavy’s launch pad have raised questions about aging infrastructure at pad 37B, which was originally built to support Saturn rocket launches in the 1960s, then mothballed until Boeing took over the facility in the 1990s for the Delta 4 program.

Boeing built the towering mobile gantry for the Delta 4 rocket, along with a then-new fixed umbilical tower with huge swing arms designed to pull away from the launcher as it climbs away from the pad.

The age of the launchpad, combined with the expensive complexity of the Delta 4 Heavy that results in very few launches spread over many years, cannot result in reliable operations.

Joshua Wong – The New Politics

6:01 pm

An evening pause: Hat tip Jim Mallamace, who accurately describes this as “a mildly amusing short sci-fi film.”

My thought in watching this short film is that I have been watching and reading sci-fi movies and books about a oppressive future imposed by technology for almost sixty years. All were written as warnings of a future to avoid. Instead, it appears we have taken them all as instruction manuals.

Modern science: Celebrating a “high priestess” instead of data

12:37 pm

The corruption of modern science and our intellectual class was well illustrated today by the following headline and article in the peer review journal Science:

Act now, wait for perfect evidence later, says ‘high priestess’ of U.K. COVID-19 masking campaign

From the article’s lead:

In May, when several prominent U.K. scientists pushed back against a Royal Society report recommending face masks to help control the spread of COVID-19, Trisha Greenhalgh was furious. The scientists argued there was insufficient support in the scientific literature for the efficacy of masks, and the U.K. government, following their lead, declined to mandate masks for the general public.

“The search for perfect evidence may be the enemy of good policy,” Greenhalgh, a physician and expert in health care delivery at the University of Oxford, fumed in the Boston Review. “As with parachutes for jumping out of airplanes, it is time to act without waiting for randomized controlled trial evidence.” [emphasis mine]

The highlighted words have been the typical argument of the global warming crowd for decades. “We can’t wait for evidence! We need to act now before it’s too late!”

Moreover, she — along with the writer of this Science article — also copies another global warming dishonest tactic, posing a false argument by claiming that the opposing scientists requried a “randomized controlled trial” to demonstrate the usefulness of masks. This is an absurd misstatement, as it ignores decades of research that already exists and was referenced by those opposing scientists, that showed that mandating widespread mask use was generally a bad idea, and would accomplish nothing good.

Chang’e-4 and Yutu-2 awake for 23rd lunar day on far side of the Moon

10:01 am

The new colonial movement: China’s Chang’e-4 lander and Yutu-2 rover have both been reactivated for their 23rd lunar day on far side of the Moon.

Yutu 2 is set to continue its journey northwest from the landing site and will target a roughly 12-inch (30 centimeters) rock on the rim of a nearby crater for analysis with a spectrometer. The rover has used that instrument to analyze a range of specimens in Von Kármán crater, notably causing a stir when it discovered an impact melt breccia initially described as “gel-like.”

It is the hope of the Chinese scientists that this rock will be ejected material from that crater and will have come from the lunar interior.

Also, though you need to read Chinese to understand how to access it, the project has released to the public another batch of data from both spacecraft.

ArianeGroup completes testing of all three Ariane 6 rocket engines

9:54 am

Capitalism in space: ArianeGroup, the joint private partnership that is building Europe’s new Ariane 6 rocket, has successfully completed all testing of the three different engines the rocket will use.

The first stage has a core engine with side strap-on solid rocket motors, while the upper stage has a different engine entirely. All three have now passed qualification tests, allowing full design and construction of the rocket itself.

Old launch tower burns down at Firefliy launchpad at Vandenberg

9:47 am

Capitalism in space: Apparently workers dismantling the old launch tower at Firefliy’s new launchpad at Vandenberg started a fire that burned the tower down.

A photo showing the former Delta II rocket’s Space Launch Complex-2 facility with flames and a huge column of black smoke rising from the distinctive blue tower began circulating on social media sites on Thursday night.

The launch site, most recently used for liftoffs of United Launch Alliance’s Delta II rockets, has been handed over to Texas-based Firefly Aerospace, which is developing a new family of rockets as an economical way to carry small- to medium-sized satellites into space.

The firm has a long-term lease to use the site with hopes of saving money by using some of the existing facilities. Firefly has plans to dismantle the historic tower, and a contractor armed with welding equipment reportedly sparked the blaze Thursday.

No word yet on whether this fire will delay Firefly’s planned first launch in the spring.

Leak on ISS traced to “fracture”

9:43 am

Not good news: According the Russian news source TASS, Russian astronauts have pinpointed the location of the slow leak on ISS to ” a fracture in the intersection compartment of the Russian Zvezda module.”

The astronaut also called it a “scratch,” which means the fracture is not yet confirmed. They will do more testing to find out if this is the leak source in the coming days.

If it is a fracture, the ramifications could be very serious. It appears the “intersection compartment” is the area where the aft docking port is located, which is also the area where many Progress freighters have docked in the twenty years since Zvezda was launched. Thus, this could be a stress fracture that can only get bigger with time. Its location might also preclude further dockings at this port, limiting arrivals of future Progress cargo ships.

Fun fact: They pinpointed this location using a floating tea bag.

The tea bag’s sway in zero gravity conditions towards the air leak overboard the space station was registered by cameras, the cosmonaut said. “We believe that we have really identified the probable leakage area. We have distributed a tea bag [in the Zvezda module] before closing the transfer chamber,” Ivanishin said.

The tea bag’s movement was recorded, the Russian cosmonaut said.

Update on InSight’s mole: It is now underground

9:29 am

InSight's mole now completely buried
Click for full image.

An update today on the mole digging tool on the Mars lander InSight has revealed that the mole appears to finally be completely buried, though it remains unclear whether its most recent digging effort had succeeded in digging downward.

We found that during the first two rounds of hammering and during the first half of the third round of hammering, the scoop went further into the sand. Since the Mole was hidden under the scoop, the penetration of the probe itself could not be observed directly.

During the hammering, the flat tether running to the probe moved considerably, but these could only be clearly identified as forward movements during the hammering on 22 August. Overall, we could estimate from the movements of the scoop that the Mole moved at most one centimetre further into the ground. It was interesting to observe that during the second half of the round of 250 hammer blows on 19 September, the scoop did not go any further, probably because it encountered duricrust. This was certainly a desired outcome, as it allowed a second Free Mole Test to be conducted. In fact, the probe continued to move according to the movements of the tether, but it could not be clearly determined that these movements brought the Mole deeper into the ground.

The image shows InSight’s arm above the filled hole, with the mole’s flat tether coming out of the ground.

They are now going to fill the hole more, and then press down with the scoop during later drilling efforts to see if this allows the mole to proceed downward. If it fails I’m not sure if there is anything else they will be able to do to get the mole to work.

Threatened collision between two big pieces of space junk does not happen

9:11 am

Follow-up observations of the two big pieces of space junk, a Soviet-era defunct satellite and a Chinese upper stage, that had a high chance of colliding yesterday has confirmed that no collision occurred.

Shortly after the time of probable collision, the CZ-4C stage passed over the Kiwi Space radar tracking station in New Zealand. According to LeoLabs, “Shortly after [time of probable collision], we will have a direct pass of CZ-4C R/B over our Kiwi Space Radar in New Zealand. We have scheduled a search mode scan during this time to ensure we only see two objects as expected and hopefully confirm that no new debris is detected.”

This is exactly what happened, with the only observed object being the single CZ-4C stage — indicating no collision had occurred.

It is fortunate nothing happened. Though the collision point was about 360 miles higher than the orbit of ISS, the debris from a collision would have been flung in all directions, some of which might have crossed the space station’s path.
