Biden fires Boeing on SLS; gives job to Acme

12:41 pm

In an interesting announcement today, the Biden administration fired Boeing as the prime contractor for SLS and gave the job to a well-known southwest company dubbed Acme.

Anticipating critical comment, White House spokesmen pointed out that Acme had a long history of use of solid-fuel rockets for crewed applications, “without loss of human life or serious injury” despite some less-than-fatal mishaps.

…The spokesperson also added, “It should be noted that Acme’s products have never killed anybody. Unfortunately the same can’t be said for Boeing.”

A deep south Martian dune with bright patches

Dune with bright patches
Click for full image.

Cool image time! Last week the MRO science team posted a new captioned image entitled “Bright and Dark Dunes” featuring a particularly large single dune in the floor of a 25-mile-wide unnamed crater located at about 68 degrees south latitude. The photo to the right, rotated, cropped, reduced, and color enhanced to post here, shows that dune. According to the caption, written by Colin Dundas of the U.S. Geological Survey’s Astrogeology Science Center in Arizona,

This image shows a large sand dune with bright patches. Martian dunes near the poles often have bright patches in the spring, when seasonal frost is lingering. However, this image is from late summer, when frost is long gone. What is going on here?

A close-up look with [MRO’s high resolution camera] provides some clues. The bright patches are made up of large ridges that look like wind-blown bedforms. Additionally, the bright patches are yellowish in the infrared-red-blue image. In enhanced color, most sand on Mars is blue but dust is yellow. This suggests that the bright bedforms are either built from, or covered by, dust or material with a different composition.

Thus, the bright patches reveal either aspect of the dune’s underlying structure, either inherent in the bedrock itself, or the texture of its surface that allows it to hold more dust. As Dundas adds, “I think more study would be needed to determine the answer in this particular case.”

There are other aspects of this dune that can be seen by a look at the wider view afforded by MRO’s context camera below.

Looking into one of Jupiter’s smaller cyclones

A northern cyclone on Jupiter
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken by the Juno probe orbiting Jupiter and enhanced first by citizen scientist Kenneth Gill and then further enhanced by citizen scientist Navaneeth Krishnan.

Sadly all the link tells us about this storm is that it is in the northern hemisphere. Based upon the colors, my guess is that it located at the high latitude where Jupiter’s bands transition to the chaotic region of storms at the poles, as seen in this earlier wide image of the gas giant’s south pole.

No scale is provided, but an earlier image of other northern hemisphere storms suggests this storm would probably cover the state of Arizona.

SpaceX: No 1st stage footage on tonight’s Starlink launch

9:22 am

During last night’s short broadcast leading to the abort at T-1:24 seconds of a launch of another 60 Starlink satellites, the company announced that it would not show the video feed from the reused first stage booster as it returned to Earth.

[A] SpaceX engineer revealed that the company would not be broadcasting live feeds from Falcon 9 B1049’s onboard cameras during the launch. The ambiguity of the comment made it impossible to determine if SpaceX was simply choosing to not show those views or if something was wrong with the camera downlink system, while the same engineer-turned-host did go on to state that “all systems are green” moments later.

No explanation for the sudden change – possibly the first webcast in years without live views from booster cameras – was given. Starlink-17 serves as a return-to-flight mission for SpaceX after Starlink-19’s failed landing, during which the rocket’s onboard cameras streamed what appeared to be clearly unusual and possibly off-nominal behavior early on in the landing process.

The article at the link then speculates that maybe SpaceX was worried about that booster’s ability to land (it will be flying its eighth time, same as the booster that failed on the earlier flight).

I am very skeptical of that theory, especially because SpaceX has never shown a reluctance to show the public its failures. Instead, I think SpaceX has decided to do an engineering test of that booster during its return, and for propriety reasons wants to keep this from public eyes. If so, the test itself might also mean they are willing to lose this booster during that test.

During the early days of their program to reuse boosters, they sometimes had the returning 1st stage do some very stressful maneuvers, producing very spectacular light shows when launched from Vandenberg on the California coast. It could be they want to test this older booster on its eighth flight in a similar manner, in order to reassess their engineering and thus make it possible to upgrade and extend the re-usability of later boosters.

Rocket Lab about to go public

9:07 am

Capitalism in space: According to news reports today, the smallsat rocket company Rocket Lab is about to sign a deal that will make it a publicly traded stock in a merger with a venture capital company.

The Wall Street Journal reported today talks between the company and Vector Acquisitions Corp were nearing completion and could be finalised with 24 hours, and was expected to see Rocket Lab raise another $650 million in cash from other private investors.

Vector is a special-purpose acquisition company, a vehicle that recruits investors and lists before pursuing a business to buy. Vector, backed by tech private equity firm Vector Capital, raised $400m on launch in September.

Rocket Lab is one of a cluster of spaceflight operators jostling for global market share in the smaller-launch market, where the focus is on achieving reliable delivery of small cargoes to lower earth orbits. Any listing would catapult Rocket Lab – whose Mahia spaceport has delivered nearly 100 satellites into orbit – into the top rank of New Zealand companies, and represents a huge blow for the local NZX. With a valuation of $5.7b, it would have ranked as one the 10 largest companies on the national exchange.

According to Rocket Lab, it is not a New Zealand company but based in the U.S., despite the bulk of its operations being in New Zealand.

I will not be surprised it Rocket Lab’s stock price quickly rises once available for purchase. Unlike Virgin Galactic, this is a real company with a real product producing real profits. It is also very well placed to garner a healthy share in the emerging launch market of smallsats that is now arriving on the scene. The company is about to initiate launches from its second launchpad at Wallops Island in the U.S., which will also allow it to finally accelerate its launch pace to the promised twice a month pace it has been promising for the last two years.

India & Russia successfully launch satellites

11:04 pm

Both India and Russia today successfully launched satellites into orbit.

For India it was their first launch in 2021. Their PSLV rocket put into orbit a Brazillian satellite for studying Earth resources. The launch also included 18 other cubesats.

Russia in turn used its Soyuz-2 rocket to launch a new generation weather satellite for studying that country’s remote Arctic regions.

SpaceX had also planned another Starlink launch but aborted the countdown with just over a minute to go. They plan to try again tomorrow.

The 2021 launch race:

5 SpaceX
4 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India

The U.S. still leads China 8 to 4 in the national rankings.

Astra wins three-launch contract from NASA

8:59 am

Capitalism in space: Astra, which as yet not achieved its first orbital launch, has won a three-launch contract from NASA valued at just under $8 million.

Astra, the Alameda-based space launch startup that recently announced its intent to go public via a SPAC merger, has secured a contract to deliver six cube satellites to space on behalf of NASA. Astra stands to be paid $7.95 million by the agency for fulfilment of the contract. This will be a key test of Astra’s responsive rocket capabilities, with a planned three-launch mission profile spanning up to four months, currently targeting sometime between January 8 and July 31 of 2022.

There is no word on when the first flight of its rocket, dubbed Rocket, will occur. The company has completed two test launches, with the second nearly making orbit.

Military admits F-35 is impossible to use, expensive, and an utter failure

3:45 pm

Another typical federal project: The military has now admitted that Lockheed Martin’s F-35 fighter jet, a decades-long project to replace the F-16, is an utter failure and must be replaced.

The list of basic problems with the jet are truly appalling.

In spite of its advanced technology and cutting-edge capabilities, the latest stealth fighter suffers from structural flaws and slew of challenges.

Most recent among them is a structural engine flaw and shortage in its production. The F-35’s engine problem is partly based in not being able to deliver them for maintenance as fast as needed, in addition to a problem with the heat coating on its rotor blades which shortens engine lifespan considerably. Defense News described it as a “serious readiness problem”, suggesting that as soon as 2022, nearly 5 to 6 per ent of the F-35 fleet could be effectively grounded as it waits for engine replacements.

Another challenge is the plane’s software. Most modern fighter jets have between 1 to 2 million lines of code in their software. The F-35 averages 8 million lines of code in its software, and it’s suffering from a bug problem. To fix this, the US Department of Defense is asking three American universities to help figure it out.

The fighter jet also suffers from a slightly embarrassing touchscreen problem. After making the switch from hard flipped switches to touch screens, pilots report that unlike a physical switch that you’re confident has been activated, touch screens in the plane don’t work 20 percent of the time says one F-35 pilot.

The worst part of this story is that this kind of incompetence has been par for the course for big federal projects like this for decades. Our government in Washington is corrupt and unqualified to even be dog catcher, but we voters don’t seem to have the courage to fire them. We certainly don’t fire the politicians who appear quite willing to encourage this corruption.

Study: Only 10% chance of catching COVID from infected person within household

3:09 pm

Holy moley! A new study of more than 7,000 households in Boston with at least one infected person has found that there is only 10% chance that another member of the household will become infected also.

US researchers analysed data from more than 7,000 homes in Boston and found more than 25,000 people lived there between March 4 and May 17, 2020. In this time frame 7,262 people caught Covid but they only passed it on to a further 1,809 people they lived with, a transmission rate of 10.1 per cent.

The paper also found the likelihood of passing the virus on to someone you live with was lower for bigger hosueholds. For example, someone in a home with three to five people — one of whom was infected — was 20 per cent less at risk than a two-person house.

The study also found that infection was closely correlated with other illnesses. If you had other health issues, such asthma, cancer, were overweight, or had liver disease your chances of getting infected rose significantly.

This report is consistent with other research, that has found infection rates in households ranged from 16.6 to 19.5 percent. All tell us that even if you spend a lot of time with someone infected, if you are healthy your risk of catching COVID is relatively low. And if you are healthy your chances are dying are almost nil.

So I ask: When you are out hiking by yourself in the great outdoors, why the heck are you wearing a mask? And why do you stupidly put one on when you might pass someone else five feet away for about two seconds? Are you that fearful of life?

Today’s blacklisted American: The pioneers who settled the west

12:28 pm

The Oklahoma Land Rush: cancelled
The Oklahoma Land Rush, wiped from history.

They’re coming for you next: A local community college in Oklahoma has removed a monument that commemorated the pioneers who settled the state in the 1800s because some people complained it was “not inclusive.”

The monument depicted the Oklahoma land run of 1889, which occurred on the day the U.S. government opened Oklahoma up to homesteaders for settlement. Apparently, there were complaints about this depiction on social media (which usually translates as a Twitter mob) as well as threats of violence. The college’s response to these mob threats?
