NASA budget passed by Congress rejects ’24 lunar landing

9:09 am

No surprise: The NASA budget that was passed by Congress this week as part of a giant omnibus bill only gave NASA 25% of the requested funds the agency says it needs to develop a human lander required for an Artemis manned mission to the Moon by ’24.

Overall, NASA will receive $23.271 billion, almost $2 billion less than requested. Importantly for the Trump Administration’s Artemis program to return astronauts to the Moon by 2024, it provides only $850 million instead of $3.4 billion for Human Landing Systems.

…The Trump Administration requested a 12 percent increase for NASA in order to fund the Artemis program: $25.2 billion for FY2021 compared to the $22.9 billion it received in FY2020. While the goal of returning astronauts to the Moon has broad bipartisan support in Congress, the Trump deadline of 2024 — set because it would have been the end of his second term if he had been reelected — won lukewarm support at best from Republicans and none from Democrats who pointed to both budgetary and technical hurdles.

It was always clear that the Democrats were not going to cooperate with Trump to could get that lunar landing during his second term. Moreover, the real goal of Artemis is not space exploration, but distributing pork. Stretching out these missions so that they take many many years achieves that goal far better than a tight competitive schedule that gets things done. This is why SLS and Orion have been under construction, with no flights, for decades, even as SpaceX moves forward with Starship/Super Heavy in only a few years.

A Biden presidency actually increases the changes that Artemis will get better funding, but that funding will always be designed to stretch out the program for as long as possible. Our policymakers in Washington really do not care much for the interest of the nation. What they care about is their own power and aggrandizement.

Chang’e-5 lunar orbiter heading to Sun-Earth Lagrange point

8:56 am

The new colonial movement: Chinese engineers have decided to extend the mission of the Chang’e-5 lunar orbiter by shifting its orbit so that it is transferred to one of the five Sun-Earth Lagrange points.

Amateur radio operators first confirmed the Chang’e-5 orbiter was still in space and heading towards the moon. Official confirmation has now been provided as to the spacecraft’s status.

Hu Hao, a chief designer of the third (sample return) phase of the Chinese lunar exploration program, told China Central Television (Chinese) Dec. 20 that the orbiter is now on an extended mission to a Sun-Earth Lagrange point. Hu said the extended mission was made possible by the accurate orbital injection by the Long March 5 launch vehicle, the same rocket which failed in July 2017 and delayed Chang’e-5 by three years. The Chang’e-5 orbiter has more than 200 kilograms of propellant remaining for further maneuvers.

While unspecified, it is believed that the Chang’e-5 orbiter will enter orbit around L1, based on the reference to planned solar observations. The orbiter is equipped with optical imagers. The team will decide on a further destination after tests and observations have been conducted, Hu said.

It makes great sense to keep the orbiter operating, and since lunar orbits tend to be unstable, going to a Lagrange point makes even more sense.

However, this decision raises an interesting point for the future. There are only five Lagrange points in the Earth-Sun system. All have great value. All also can likely sustain a limited number of satellites and spacecraft. Who coordinates their operations? What happens if China fills each with its spacecraft? For example, the James Webb Space Telescope is aiming for Lagrange point #2, a million miles from Earth in the Earth’s shadow. While Chang’e-5 is presently heading to a different point, what happens if China changes its mind and puts Chang’e-5 in Webb’s way?

As far as I know, there has been no discussion of this issue in international circles.

Russia recovers boosters dropped on Russia

8:42 am

The new colonial movement: Dmitri Rogozin, head of Russia’s Roscosmos space agency, announced this past weekend the recovery of the first stage and boosters from a December 18th Vostochny launch that, because of the polar orbit of the satellite, were dropped on Russian territory.

On Friday, a Soyuz 2.1b rocket launched from the Vostochny Cosmodrome, carrying its payload of 36 OneWeb satellites into space. Although Russia’s newest spaceport is located in the far eastern part of the country, it still lies several hundred kilometers from the Pacific Ocean.

This means that as Soyuz rockets climb into space from this location, they drop their stages onto the sparsely populated Yakutia region below. With the Soyuz rocket, there are four boosters that serve as the rocket’s “first stage,” and these drop away about two minutes after liftoff. Then, the “Blok A” second stage drops away later in the flight.

Although the Yakutia region is geographically rugged and sparsely populated, the Russian government does a reasonably good job of establishing drop zones for these stages and keeping them away from residential areas. This is what happened, as usual, with Friday’s launch. [emphasis mine]

The focus of the article at the link is the silly jabs at SpaceX that Rogozin included in his announcement. The real story, however, is that the Russian government, in deciding to build a new spaceport in Vostochny, made the conscious decision to place it where it would have to dump rockets on its own territory. They could have instead built this new spaceport on the Pacific coast, and avoided inland drop zones, but did not for reasons that escape me.

Tells us a lot about that government and what it thinks of its own people. But then, governments rarely care much about ordinary people, as those who revel in the power of government are generally more interested in that power than in doing what makes sense or is right.

China completes first launch of Long March 8 rocket

8:28 am

The new colonial movement: China today successfully launched for the first time its new Long March 8 rocket, designed at some point to mimic the Falcon 9 by vertically landing its first stage and reusing it. (Note: link fixed!)

On this launch the rocket had no such recovery capability.

The leaders in the 2020 launch race:

34 China
25 SpaceX
15 Russia
6 ULA
6 Rocket Lab

The U.S. still leads China 40 to 34 in the national rankings.

Oregon protest live

12:51 pm

UPDATE: The police have agreed to back off, if the protesters stay on the sidewalks. At one point one protester smashed the glass on the locked access door that I think is normally open for public access to the legislature.

The key final moment in this protest was when it appears the police used their military vehicle to ram and essentially total one of the trucks that the protesters had placed on the road to block it. The police rammed it, and then backed off to their previous position. The protesters than assembled at that position, pressuring the police hard. This seemed to force the negotiation that caused the police to leave.

Original post:
————————–
It appears that a group showed up to enter the assembly building to watch the legislative session, as legally allowed, and were prevented and attacked. They then sent out a flash mob announcement, and when heavy military style vehicles from the police arrived, announcing that they are an “unlawful assembly”, the protesters blocked their street with their own buses and vehicles.

The live stream is active, and the protest is ongoing. What will happen is unknown, as the protesters are refusing to leave and the police have been bringing in reinforements.

Update on Starship protype #9

10:25 am

Link here. The article not only provides video and the status of prototype #9 after its fall against the side of the assembly building, it also provides the status of the numerous other prototypes, both of Starship and Super Heavy.

In addition, the article shows the clean-up of the remains of Starship #8 from the landing pad.

All told, it appears that Starship #9 has been repaired from its fall, and is being prepped for a 50,000 foot flight sometime around New Year’s.

Lockheed Martin buys Aerojet Rocketdyne for $4.4 billion

10:20 am

Capitalism in space: Lockheed Martin officials announced yesterday that it will buy the rocket engine company Aerojet Rocketdyne for $4.4 billion.

James Taiclet, Lockheed Martin’s president and CEO, said the acquisition gives the company a larger footprint in space and hypersonic technology. He said Aerojet Rocketdyne’s propulsion systems already are key components of Lockheed Martin’s supply chain across several business areas. “The proposed acquisition adds substantial expertise in propulsion to Lockheed Martin’s portfolio,” the company said in a news release.

Aerejet Rocketdyne has been in trouble because it has had problems finding customers for its engines. This acquisition will give Lockheed Martin more technical capabilities should it decide to enter the launch industry with its own rocket.

Samples from space!

9:16 am

Scientists from both the Japanese Hayabusa-2 mission to the asteroid Ryugu and the Chinese Chang’e-5 mission to the Moon announced yesterday the total amount of material they successfully recovered.

The numbers appear to diminish the Japanese success, but that is a mistake. Getting anything back from a rubble-pile asteroid that had never been touched before and is much farther away from Earth than the Moon was a very great achievement. The 5.4 grams is also more than fifty times the minimum amount they had hoped for.

This is also not to diminish the Chinese achievement, They not only returned almost four pounds, some of that material also came from a core sample. They thus got material both from the surface and the interior of the Moon, no small feat from an unmanned robot craft.

Scientists from both nations will now begin studying their samples. Both have said that some samples will be made available to scientists from other countries, though in the case of China it will be tricky for any American scientist to partner with China in this research, since it is by federal law illegal for them to do so.

Mysterious signal detected possibly coming from Proxima Centauri

9:05 am

The uncertainty of science: Breakthough Listen, the project funded to the tune of $100 million by billionaire Yuri Milner with the goal of listening for alien radio signals, in 2019 detected a single radio tone that appeared to be coming from the nearest star, Proxima Centauri.

A team had been using the Parkes radio telescope in Australia to study Proxima Centauri for signs of flares coming from the red dwarf star, in part to understand how such flares might affect Proxima’s planets. The system hosts at least two worlds. The first, dubbed Proxima b upon its discovery in 2016, is about 1.2 times the size of Earth and in an 11-day orbit. Proxima b resides in the star’s “habitable zone,” a hazily defined sector in which liquid water could exist upon a rocky planet’s surface—provided, that is, Proxima Centauri’s intense stellar flares have not sputtered away a world’s atmosphere. Another planet, the roughly seven-Earth-mass Proxima c, was discovered in 2019 in a frigid 5.2-year orbit.

Using Parkes, the astronomers had observed the star for 26 hours as part of their stellar-flare study, but, as is routine within the Breakthrough Listen project, they also flagged the resulting data for a later look to seek out any candidate SETI signals. The task fell to a young intern in Siemion’s SETI program at Berkeley, Shane Smith, who is also a teaching assistant at Hillsdale College in Michigan. Smith began sifting through the data in June of this year, but it was not until late October that he stumbled upon the curious narrowband emission, needle-sharp at 982.002 megahertz, hidden in plain view in the Proxima Centauri observations. From there, things happened fast—with good reason. “It’s the most exciting signal that we’ve found in the Breakthrough Listen project, because we haven’t had a signal jump through this many of our filters before,” says Sofia Sheikh from Penn State University, who helmed the subsequent analysis of the signal for Breakthrough Listen and is the lead author on an upcoming paper detailing that work, which will be published in early 2021. Soon, the team began calling the signal by a more formal name: BLC1, for “Breakthrough Listen Candidate 1.”

The data so far does not suggest this signal was produced by an alien technology. Instead, it likely is a spurious signal from some natural or human source, picked up by accident, as was the SETI “Wow” signal that for years puzzled astronomers until they traced it to a comet.

However, as they do not yet have an explanation, it is a mystery of some importance.

SpaceX completes 25th orbital launch in 2020

8:45 am

Capitalism in space: SpaceX today successfully completed its 25th orbital launch in 2020, using its Falcon 9 rocket to put an American spy satellite into orbit.

The first stage successfully landed at Cape Canaveral, completing its fifth flight.

Not only is 25 launches in a single year a new record for SpaceX, it is also four more launches than the company predicted it would achieve in 2020.

This was also the 40th successful American orbital launch in 2020, the first time since 1968 that the U.S. has had that many launches. In 1968 the launches were almost all dictated by the government, on rockets controlled by the government. Today, the rockets are all privately designed and owned, with the small number of government launches occurring with the government merely the customer buying a product.

The leaders in the 2020 launch race:

33 China
25 SpaceX
15 Russia
6 ULA
6 Rocket Lab

The U.S. now leads China 40 to 33 in the national rankings. The rankings also should not change significantly in the last two weeks of the year, as the U.S. has no more scheduled launches and China and Russia only one.

Maricopa County election board defies state subpoenas

2:18 pm

And they expect the public to trust them? The election board of Maricopa County has decided to defy the subpoenas issued by the state’s legislature for getting a full audit of its election results, and will instead file a lawsuit against those legislators.

It seems to me that if there was nothing wrong with the Dominion tabulators and the count, than the board would welcome this audit. That they are stonewalling it is if anything evidence that there is likely something they are hiding.

We have now reached the Rubicon. Are our elected officials truly in charge, or are they to be ordered around by unelected bureaucrats like mere serfs? If the state legislature and the governor does not act here, then they are no more than figureheads, and we are now ruled by fiat, by the bureaucracy. Arizona does not have a democracy ruled by law any longer.
