Biden administration to formulate new regulations governing in-space commercial activities

11:09 am

We’re here to help you: The Biden administration has now officially announced its plans to formulate new regulations governing in-space commercial activities, such as satellite repair, orbital refueling stations, and removal of space junk, as part of a space strategy workshop statement released last week by the FCC.

The new White House initiative is a follow-on effort [to one started during the Trump administration], aimed at fleshing out the domestic rules, and possibly future regulations, for “non-traditional” space activities that today either fall between jurisdictional cracks or simply are not covered by current law, according to a US government source involved.

Another thrust of the Biden administration effort is to get in front of the governance issues in order to shape future global norms and rules, including for military activities — ahead of China, which also is seeking to be a leader in how humankind expands its reach to the stars.

Kamala Harris announced this new regulatory effort, outlined in this strategy document [pdf], and added that it will be led by the National Space Council, despite the fact that the FCC scooped her by a full week in announcing it. This quote below from her speech announcing this initiative also illustrated her empty-headed, cliche-ridden mentality:

“We will do this work to make sure our nation remains a role model for the responsible use of space,” Harris said in a speech during a visit to the Chabot Space & Science Center in Oakland, Calif. noting that the US “must write new rules to provide the clarity” needed by government and industry for 21st century space operations.

“We must think about where we now stand and where we must go,” she said. “The opportunity of space must guide our work in the 21st century. to do so, must deepen our partnerships with the private sector.”

Despite the vapid content of Harris’s speech, make no mistake she and the federal bureaucracy that is dominated and controlled by the Democratic Party knows exactly where it wants things to go: It wants power and control, and is very unhappy that in the past five years private enterprise has wrested that power and control from it in space. These new regulations will be shaped entirely with the goal of squelching the freedom of private companies so that the government runs things again.

Professional software hacker demonstrates how to hack Starlink terminals

10:49 am

A professional software hacker not only recently succeeded in hacking the terminals SpaceX sells customers to use its Starlink satellite internet service, he first got a bounty from SpaceX for doing so, then made his technique freely available on the web for everyone else.

[Lennert] Wouters is now making his hacking tool open source on GitHub, including some of the details needed to launch the attack. “As an attacker, let’s say you wanted to attack the satellite itself,” Wouters explains, “You could try to build your own system that allows you to talk to the satellite, but that’s quite difficult. So if you want to attack the satellites, you would like to go through the user terminal as that likely makes your life easier.”

The researcher notified Starlink of the flaws last year and the company paid Wouters through its bug bounty scheme for identifying the vulnerabilities. Wouters says that while SpaceX has issued an update to make the attack harder (he changed the modchip in response), the underlying issue can’t be fixed unless the company creates a new version of the main chip. All existing user terminals are vulnerable, Wouters says.

Starlink says it plans to release a “public update” following Wouters’ presentation at Black Hat this afternoon, but declined to share any details about that update with WIRED prior to publication.

Wouters is a researcher at the Belgian university KU Leuven.

While it can certainly help SpaceX to figure this out, by publishing the hack to the world Wouters looks like a blackmailer unsatisfied with his payoff who is now following through with his blackmail threat. One also wonders why SpaceX, as part of its bounty payment, did not require Wouters to sign a non-disclosure agreement.

Formula 1 crash right after start

6:01 pm

An evening pause: This short analysis of a spectacular race track crash right at the start of a Formula 1 race illustrates well the sophistication of modern technology, not only in protecting the driver’s life but in providing the information for reconstructing the cause of the accident. And it all happens during an ordinary sports broadcast.

You’ll probably want to watch this more than once to catch how one car gets flipped over on its back.

Hat tip Tom Wilson.

SpaceX launches 46 more Starlink satellites

2:49 pm

Capitalism in space: SpaceX today used its Falcon 9 rocket to launch another 46 Starlink satellites into orbit from Vandenberg Space Force Base in California.

The first stage completed its 10th flight, landing on a drone ship in the Pacific. It was also the fourth flight for both fairing halves. During the live stream the announcer also mentioned that because SpaceX has recently switched to using Starlink for transmitting its launch video feeds, the loss of picture signal that use to occur during the landing of the first stage on the drone ship has almost completely vanished.

The leaders in the 2022 launch race:

36 SpaceX
30 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise now leads China 51 to 30 in the national rankings, and the entire world combined 51 to 48.

I should also add that the United States has now matched the number of launches achieved in 1962, the nation’s fifth highest total of successful launches in a single year.

Pushback: Blacklisted doctors join lawsuit against Biden administration COVID censorship

2:16 pm

Correct from the start despite government censorship
Correct from the start despite government censorship

Bring a gun to a knife fight: Three well-known research doctors have now added their names to a lawsuit filed by two states that accuses the Biden administration of coordinating with major social media companies like Google and Twitter to censor all posts critical of administration COVID policies.

Drs. Jayanta (Jay) Bhattacharya, Martin Kulldorff and Aaron Kheriaty joined the lawsuit filed by the states of Missouri and Louisiana, alleging that the Centers for Disease Control and Prevention (CDC) and Department of Homeland Security (DHS) worked with Big Tech companies to censor Americans discussing the pandemic. The doctors alleged they were censored on social media platforms for expressing views in opposition to the positions of the federal government, their representation, the New Civil Liberties Alliance (NCLA), said in a Tuesday press release.

Kheriaty was blackballed by his hospital and banned from seeing patients back in October ’21 because after looking the data he had decided to recommend his patients not get the jab.

Kulldorff, one of the world’s foremost experts on vaccines, was blacklisted from Twitter, Linkedin and the CDC in August ’21, also because he challenged the government mandates that required people to get the COVID shots.

Kulldorff and Bhattacharya were co-authors of the Great Barrington Declaration, which condemned the lockdowns and mandates and instead called for a more traditional focused policy for dealing with the Wuhan flu:

Curiosity finally looks out into Gediz Vallis

12:56 pm

First look into Gediz Vallis
Click to view full mosaic.

Overview map
Click for interactive map.

Cool image time! Curiosity’s right navigation camera today produced the mosaic above, cropped and reduced to post here, taking its first good look into Gediz Vallis, the canyon that the rover has been aiming for since it landed on Mars ten years ago.

The green dot on the overview map to the right marks the approximate location of a recurring slope lineae, a streak that comes and goes depending on the seasons whose cause remains uncertain. The yellow lines show the approximate area covered by the mosaic. The red dotted lines show Curiosity’s upcoming route. According to previously announced plans, the rover will not head straight into Gediz Vallis, but circle to the west or right of the mesa to the right of Kukenan.

The valley of course looks spectacular. For scale, the cliff face of Kukenan is estimated to be about 1,500 feet high.

The most important revelation from this image however is the ground terrain. It looks like Curiosity will have no problem moving forward into the canyon from this point, something the science team could not know for sure until the rover reached the saddle and could look down and actually see ahead.

InSight seismometer data suggests no underground ice at landing site

9:25 am

Using a computer model combined with seismometer data gathered by the Mars lander InSight, scientists have concluded that there is little or no underground ice in the equatorial region where InSight sits.

From the paper’s abstract:

We use rock physics models to infer cement properties from seismic velocities. Model results confirm that the upper 300 m of Mars beneath InSight is most likely composed of sediments and fractured basalts. Grains within sediment layers are unlikely to be cemented by ice or other mineral cements. Hence, any existing cements are nodular or formed away from grain contacts. Fractures within the basalt layers could be filled with gas, 2% mineral cement and 98% gas, and no more than 20% ice. Thus, no ice- or liquid water-saturated layers likely exist within the upper 300 m beneath InSight. Any past cement at grain contacts has likely been broken by impacts or marsquakes.

As the lander sits just north of the equator in the red planet’s equatorial zone, which ample orbital data has suggested is a dry region (as shown in the global map below), this result is not a surprise. It does provide further confirmation however of this conclusion, that if there is any water on Mars within 30 degrees latitude of the equator, it will be deep underground, and likely only in certain regions.

Another and this time longer static fire tests for Superheavy prototype #7

9:02 am

Capitalism in space: SpaceX engineers yesterday conducted a second static fire engine test of the 7th prototype of its Superheavy first stage booster, firing a different engine for 20 seconds.

The action ramped up on Thursday (Aug. 11) for Booster 7, which conducted a much longer static fire on Starbase’s orbital launch mount. The burn, which occurred at 3:48 p.m. EDT (1948 GMT), lasted for 20 seconds, SpaceX said via Twitter (opens in new tab).

The long-duration burn aimed to “test autogenous pressurization,” according to a tweet posted by Musk (opens in new tab) shortly before Booster 7 fired up.

Expect these engine tests to occur on a regular basis over the next few weeks, as engineers ramp up their operations in preparation for the first orbital flight of both prototype #7 with Starship prototype #24 stacked on top.
