Die Twinnies – Bayernmädels

An evening pause: Hat tip Jim Mallamace, who writes,

Good friends, Astrid Paster and Franziska Pauli, are Die Twinnies. This was the girls’ debut TV performance for the popular Austrian entertainment show, “Musikantenstadl.”

This was recorded in 2009. It is said the career length of a child entertainer is about the same as the lifespan of a pet. That was pretty much true for Die Twinnies. We enjoy such performances while we can.

It might be lip-synched, but so what? Fun stuff.

SpaceX launches Space Force GPS satellite

Capitalism in space: SpaceX tonight successfully launched the GPS satellite that on a previous launch had experienced a launch abort at T-2.

This was a completely new Falcon 9 rocket, with two of its original engines replaced after the company had traced the issue that caused the launch abort. The first stage successfully landed on the drone ship in the Atlantic Ocean, and will fly again on the next GPS launch by SpaceX for the Space Force.

The satellite has been deployed successfully, completing the launch.

The leaders in the 2020 launch race:

27 China
19 SpaceX
12 Russia
4 ULA
4 Europe (Arianespace)
4 Rocket Lab

The U.S. now leads China 30 to 27 in the national rankings.

Rocket Lab will try to recover 1st stage on next launch

Capitalism in space: Rocket Lab announced today that it will attempt to recover the 1st stage of its Electron rocket on its next launch, using parachutes to slow its descent into the ocean and then fishing from the sea.

On its next mission set for liftoff later this month, Rocket Lab will try to recover the first stage of its Electron small satellite launcher after parachuting into the Pacific Ocean downrange from the company’s privately-run spaceport in New Zealand, officials announced Thursday.

The attempt to retrieve the Electron rocket’s first stage moves Rocket Lab closer to eventually capturing falling boosters in mid-air with a helicopter, then reusing the hardware. The reuse initiative is aimed at increasing Rocket Lab’s flight rate, and could result in cost savings, according to Peter Beck, the company’s founder and CEO.

The flight is presently scheduled for November 15 from New Zealand. It appears the goal with this recovery is not to reuse the 1st stage, but to recover it so they can determine how it fared during re-entry. For re-use they will capture the first stage using a helicopter, before splashdown and is exposed to saltwater.

When they attempt the helicopter capture on an actual launch remains unclear.

Starship hop tentatively set for Nov 9-11

Capitalism in space: Based on SpaceX’s road closure requests, it now appears that the 50,000 foot hop by the eighth Starship prototype will occur sometime between November 9th and November 11th.

This schedule remains very uncertain, as the company needs to do other tests before the hop. Depending on when these tests happen and what they learn after each, the overall schedule might change.

Bezos sells another $3 billion of Amazon shares

Jeff Bezos continues to accelerate his sale of his Amazon stock, selling another $3 billion this week.

In August, Bezos offloaded more than $3.1 billion of Amazon shares, after selling more than $4.1 billion worth of shares in February. The sales this week bring his total cash out in 2020 to more than $10.2 billion so far, which is a notable jump from 2019, when Bezos sold $2.8 billion worth of shares.

While Bezos had originally said these sales were for financing his space company, Blue Origin, it now appears that the bulk of this new money is aimed at funding environmental political organizations such as the Environmental Defense Fund, the Natural Resources Defense Council and the World Wildlife Fund.

New owners for Vector to revive company

Capitalism in space: The new owners for bankrupt smallsat rocket company Vector have announced that they plan to revive the company.

In their announcement they confirmed that the key problem that killed the original company were engineering issues with its chosen engine design.

One thing they did wrong was the technology the used for their engines. “They had some Achilles’ heels associated with their technical approach. They were trying to use a propellant combination that was untested in the industry,” said Chris Barker, who serves as Vector’s chief rocket scientist. “They were struggling with trying to get performance that they knew they needed for a small launcher to be successful, and ultimately their test program was unsuccessful.”

Vector had been developing engines that used propylene and liquid oxygen propellants. The new Vector plans to instead use engines powered by a more conventional combination of liquid oxygen and refined kerosene, or RP-1, propellants. Barker has been developing such engines since the 1990s for companies such as Space America and Earth to Sky.

The new owners also stated that initially they plan to target the suborbital business field. Their main focus right now is redesigning the Vector-R rocket in conjunction with their engines.

NASA officially expresses concerns about proposed private communications constellation

For what appears to be an unprecedented action, NASA has officially expressed opposition to a proposed private satellite constellation by the company AST & Science.

NASA’s position was released in a comment to the FCC, where the company has requested a communications license to operate its satellites.

At issue are plans put forth by AST & Science, which intends to build a constellation of more than 240 large satellites, essentially deploying “cell towers” in space to provide 4G and possibly 5G broadband connection directly to cell phones on Earth. The company, based in Midland, Texas, calls its constellation “SpaceMobile” and has raised an estimated $120 million.

The space agency felt compelled to comment on AST’s proposal for several reasons. Most notably, the proposed altitude for the SpaceMobile constellation lies near the “A-Train,” a group of 10 Earth-science monitoring satellites operated by NASA and the US Geological Survey, as well as partners in France and Japan. “Historical experience with the A-Train constellation has shown that this particular region of space tends to produce a large number of conjunctions between space objects,” the NASA letter states.

The satellites are also very large. In order to provide service, AST plans to build spacecraft with large phased array antennae—900 square meters. According to NASA, in planning for potential conjunctions with other satellites and debris in this orbit, this would require proscribing a “hard-body radius” of 30 meters, or as much as 10 times larger than other satellites.

Maneuvering around the proposed SpaceMobile constellation would be extraordinarily taxing, NASA said. “For the completed constellation of 243 satellites, one can expect 1,500 mitigation actions per year and perhaps 15,000 planning activities,” the space agency stated. “This would equate to four maneuvers and 40 active planning activities on any given day.”

The company has said it is willing to work with NASA to ease its concerns. For NASA to take this particular step however is most strange, especially considering the size of this constellation, 240 satellites. This number is tiny compared to the multi-thousands being proposed by SpaceX, Amazon, and OneWeb. Their large size footprint certainly could be a factor, but it does seem puzzling for the space agency to pick out this particular constellation for opposition, and none of the others.

SpaceX to live stream 50,000 foot hop of Starship

Capitalism in space: Elon Musk yesterday announced that SpaceX will publicly live stream the 50,000-foot hop of Starship prototype #8, expected sometime in the next two weeks. His tweet:

Sure, although it might be quite a short livestream! Lot can go wrong, but we’ll provide video, warts & all. You will see every frame that we do.

Up until now the public has had to depend on the independent live streams being put out by local residents still living in Boca Chica, Texas, which did not know SpaceX’s exact schedule. When SpaceX does it they will likely provide more specific launch times. They will also probably provide detailed accurate commentary.

Also, this update on the status of Starship development notes that the primary goal of that hop is testing the ability of the ship’s fins and systems to control the ship’s initial descent on its return to Earth, flying on its side like the Space Shuttle. If they have problems getting the ship upright for a vertical landing and it ends up in the ocean that will not surprise them. A successful vertical landing would be icing on the cake.

U.S. court orders India’s s space agency ISRO to pay $1.2 billion

A U.S. court has ordered Antrix, the commercial arm of India’s space agency ISRO, to pay $1.2 billion to Devas, a private company with operations in both India and the United States, for a contract they canceled arbitrarily in 2011.

This is a very complicated story going back many years. ISRO’s Antrix and Devas had agreements beginning in 2005 to work together to develop commercial satellites, with Antrix building the satellites and Devas commercializing bandwidth. In 2011 the India government cancelled the contracts unilaterally.

On February 25, 2011, Antrix issued a termination notice to Devas, which among other things stated that the policy decision was of the central government, acting in its sovereign capacity is the event of force majeure, which was an occurrence on February 23, 2011, PTI report said. “The scope and duration of the said decision cannot be anticipated. It is likely to be indefinite. It is not possible for Antrix to take any effective step to resume the obligations under the agreement,” Antrix was quoted as saying.

One of the reasons for the cancellation were accusations that payoffs were occurring between officials at both Antrix and Devas to make the deal happen.

Devas has been fighting in numerous courts for years to get compensation for that cancellation.

ISRO can probably ignore this U.S. court decision, except that if it does it will make it very difficult, if not impossible, for ISRO to do any work in partnership with the U.S., such as in the Artemis program. As soon as they try to do so, Devas will slap a lien on that operation, demanding payment.

War between two Spanish space balloon companies

Capitalism in space: A legal battle is developing between two different Spanish high altitude space balloon companies, one that came first, and a second that is being backed by a venture capitalist who had previously worked at the first.

Jose Mariano Lopez Urdiales, an MIT-trained aeronautics engineer who founded Zero 2 Infinity 11 years ago, says Kemel Kharbachi, the now CEO of EOS X Space, worked closely with the company to raise a €1m investment for Zero 2 Infinity. But the funding deal never happened.

Instead, Kharbachi, whose previous experience has focused on tourism and catering, has emerged to build his own rival space balloon business.

It does appear, from the details outlined in the article, that Kharbachi essentially stole the concept and designs from Zero 2 Infinity in order to form his own company.

As these Spanish companies fight it out, a third company in America, Space Perspectives, hopes to begin flying tourists on its stratospheric balloon, dubbed Neptune, by ’24.

ESA maps out first launch schedule for new rockets

Capitalism in space? The European Space Agency (ESA) today laid out the development roadmap that will lead to the launch of two new rockets, the Vega-C being built by the Italian company Avio, and the Ariane 6 being built by ArianeGroup.

The Vega-C is a more powerful version of the Vega rocket, aimed at capturing the smaller satellite market. It maiden flight is now scheduled for June ’21.

The Ariane 6 is aimed at replacing the Ariane 5, Europe’s big workhorse rocket, but to do so at a lower cost. Its maiden flight is now set for the second quarter of ’22, a significant delay from the previously announced target date in ’21, which itself was a delay from the original late ’20 launch date.

Ariane 6 however has not succeeded in cutting costs enough to match its competitor SpaceX, and thus it continues to have trouble attracting customers, even among ESA’s partner nations that it is meant to serve. These issues have led to rumors that ESA is already looking to either significantly upgrade Ariane 6 (before it even flies), or replace it entirely wit a new re usable rocket.

SpaceX finds clogged valves in several Merlin engines

Capitalism in space: SpaceX has discovered that the problem that caused a recent launch abort of a GPS satellite was a coating that clogged valves in several newer Merlin engines.

Hans Koenigsmann, vice president of build and flight reliability at SpaceX, said teams initially weren’t able to figure out why two of nine engines triggered early-start sensors on Oct. 2, which forced computers to automatically scrub seconds before liftoff. After the engines were removed and shipped to Texas for testing, the anomaly surfaced again when sensors detected higher-than-expected engine chamber pressures.

The cause: a minuscule, almost undetectable amount of “masking lacquer,” which is used to protect engine components and surfaces during the production process. The lacquer is almost like a bright red nail polish. “We found a relief valve – a little line that goes to the relief valve – blocked in the gas generator,” Koenigsmann told reporters Wednesday. “That little red substance was blocking a relief valve that caused it to function a little bit earlier than it was supposed to.”

The gas generators are almost like little rocket engines themselves – they’re used to power a pump that then feeds propellants into the main engine chamber. But the blockage caused certain processes to begin too early.

Once the lacquer was removed the engines functioned perfectly.

The issue was also found in two engines on the new booster that was going to launch astronauts to ISS, which explains why that mission was delayed. The company is swapping out the engines, and is still targeting November 14th for that launch. In addition, NASA wants it to fly at least two missions beforehand to demonstrate the problem is fixed. One will be that GPS satellite, on November 4th. The other could be one of three different payloads on SpaceX’s busy schedule.

Initial price for Starlink: $99 per month?

According to a CNBC article today, SpaceX is now offering a beta version of its Starlink internet service to customers as the price of $99 per month, plus a $499 charge for equipment.

SpaceX is expanding the beta test of its Starlink satellite internet service, reaching out via email on Monday to people who expressed interest in signing up for the service.

Called the “Better Than Nothing Beta” test, according to multiple screenshots of the email seen by CNBC, initial Starlink service is priced at $99 a month – plus a $499 upfront cost to order the Starlink Kit. That kit includes a user terminal to connect to the satellites, a mounting tripod and a wifi router. There is also now a Starlink app listed by SpaceX on the Google Play and Apple iOS app stores.

“As you can tell from the title, we are trying to lower your initial expectations,” the emails said, signed Starlink Team. “Expect to see data speeds vary from 50Mb/s to 150Mb/s and latency from 20ms to 40ms over the next several months as we enhance the Starlink system. There will also be brief periods of no connectivity at all.”

SpaceX did not confirm this story with CNBC. If it is real, the price is disappointingly high, and might very well limit Starlink’s potential. Then again, this is only the beta version. Later versions when under full operation and available to many more customers might bring that price down.
