The tweet however provides no date for the test, nor any information about this particular engine itself.
This is preliminary design work involving Earth-based tests. A later phase, not yet awarded, will move on to orbital tests.
Most of this new private capital apparently came from Saudi Arabia and Greece, and the constellation will start out focused on serving those regions as well as Luxembourg.
Sunspot update: Solar activity continues to exceed sunspot predictions
It is the beginning of September and time to post another update on the Sun’s ongoing solar cycle. Below is NOAA’s monthly graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere, with the activity in August now added. I have also added some additional details to the graph to give the numbers a larger context.
Though sunspot activity dropped in August it remained significantly above the predictions of the panel of government solar scientists put together by NOAA. The predicted sunspot number for August, as indicated by the red curve, was supposed to be about 48. The actual number was 75.
Pushback: Maine parent wins lawsuit against school board for attempting to ban him
McBreairty speaking in front of the Hermon town council about the
lawsuit against him. Click for video from which this image was captured.
Bring a gun to a knife fight: Shawn McBreairty, a Maine parent who had repeatedly challenged two different local school districts, including his own, for their efforts to teach the queer agenda to little children, yesterday won a $40K settlement from one of those school boards, Regional School Unit #22, after a court judge had ruled that the board’s actions to ban and censor McBreaity clearly violated his first amendment rights.
This is an update of an earlier August 1, 2022 blacklist column. Because McBreairty had tried to read aloud at a board meeting the pornography contained in several books that the school board had approved for its school children, he was silenced, then banned from attending school board meetings, both in person and virtually, for the next eight months.
When the judge ruled entirely in McBreairty’s favor, issuing a temporary injunction against the school board’s actions, the board clearly recognized its case would not hold up in court, and it chose to settle, paying $40K for McBreairty’s legal fees. As the judge noted in her decision:

Chinese astronauts complete first spacewalk using new Wentian module
The new colonial movement: Chinese astronauts yesterday completed their first spacewalk using the airlock on the new Wentian module that was recently launched to that nation’s Tiangong-3 space station.
The spacewalk lasted six hours, and was mostly designed to test the airlock itself as well as do the first tests of Wentian’s own robot arm. It appears they also installed an “extended pump set”, whatever that is, and did other work near the hatch. More here.
NASA is paying Boeing twice as much as SpaceX for its manned flights
Capitalism in space: in an excellent analysis of the total amount NASA will pay both SpaceX and Boeing for all their manned flights to ISS before the station retires, Eric Berger at Ars Technica has determined that the agency will essentially pay Boeing twice as much per flight.
In 2014, NASA narrowed the crew competition to just two companies, Boeing and SpaceX. At that time, the space agency awarded Boeing $4.2 billion in funding for development of the Starliner spacecraft and six operational crew flights. Later, in an award that NASA’s own inspector general described as “unnecessary,” NASA paid Boeing an additional $287.2 million. This brings Boeing’s total to $4.49 billion, although Finch told Ars that Boeing’s contract value as of August 1, 2022, is $4.39 billion.
For the same services, development of Crew Dragon and six operational missions, NASA paid SpaceX $2.6 billion. After its initial award, NASA has agreed to buy an additional eight flights from SpaceX—Crew-7, -8, -9, -10, -11, -12, -13, and -14—through the year 2030. This brings the total contract awarded to SpaceX to $4.93 billion.
Since we now know how many flights each company will be providing NASA through the lifetime of the International Space Station, and the full cost of those contracts, we can break down the price NASA is paying each company per seat by amortizing the development costs.
Boeing, in flying 24 astronauts, has a per-seat price of $183 million. SpaceX, in flying 56 astronauts during the same time frame, has a seat price of $88 million. Thus, NASA is paying Boeing 2.1 times the price per seat that it is paying SpaceX, inclusive of development costs incurred by NASA.
Despite the larger payments to Boeing, the company could very well lose money on Starliner. The higher cost to NASA from Boeing is due almost entirely because the agency was absorbing more of its initial development cost. SpaceX’s Dragon capsule had already been flying cargo missions to ISS when these manned contracts were awarded. SpaceX merely had to upgrade its manned capsule. Boeing had to design and build it from scratch. Moreover, the contracts were fixed price, which means Boeing had to absorb more than a half billion in additional costs when it had to refly the unmanned demo flight of Starliner.
Finally, because of the delays, Boeing won less NASA business. It also has gotten none of the private commercial manned flights that are going on right now. Those contracts went to SpaceX, including all the profits. Whether Boeing can eventually win some private contracts down the road is unknown. It will certainly have to lower its price to compete with SpaceX.
Rocket Lab completes first static fire test of previously flown rocket engine
Capitalism in space: Rocket Lab has successfully completed for the first time a full duration static fire test using one of its Rutherford rocket engines that had been flown on a launch earlier this year, recovered, and refurbished.
The engine was previously successfully launched to space and returned to Earth during Rocket Lab’s recent recovery mission, ‘There And Back Again’, launched on May 2, 2022. The mission was the first time Rocket Lab attempted a mid-air capture of Electron’s first stage, using parachutes on the rocket to slow its descent from space before a helicopter plucked the rocket from the sky as it approached Earth’s surface. The Electron stage was ultimately released for a soft ocean splashdown, before it was collected by vessel and returned to Rocket Lab’s production complex.
The refurbished Rutherford engine passed all of the same rigorous acceptance tests Rocket Lab performs for every engine, including 200 seconds of engine fire and multiple restarts. Data from the test fire shows the engine produced full thrust of 21kNs within 1000 milliseconds of ignition and performed to the same standard of a newly-built Rutherford engine. This Rutherford engine will now continue as an engine life-leader for future Rutherford development.
I have embedded a video of the full test below. This achievement makes Rocket Lab only the third company to successfully refire a previously flown engine, after SpaceX and NASA’s space shuttle engines. It might also be the first time an engine recovered from the ocean has been successfully refurbished. SpaceX had tried to do the same with early Falcon 9 first stages, before they could land vertically, but all accounts suggested the salt water made the engines unusable.
Based on the the quote above, however, this engine will not be used on a future flight, but for testing only. The company still intends to catch the stages as they descend by parachute with a helicopter, which will then transport them safely to land. Further attempts to do so will take place in later launches this year.
SLS countdown resumes
NASA has resumed the countdown for the launch of the SLS rocket on Saturday, September 3, with a two-hour launch window beginning at 2:17 pm (Eastern).

On Mars you can find glaciers everywhere in the mid-latitudes
Click for full image.
Cool image time! If you ever decide to have some fun exploring the archive of images being sent back to Earth by the high resolution camera on Mars Reconnaissance Orbiter (MRO), always remember that the latitude of the image will almost immediately help to explain the strange features that you see in each picture.
The hi-res photo to the right, rotated, cropped, and reduced to post here, was taken on May 22, 2022 and provides us a great example. The jumbled features in the depression on the image’s right half surely look like the glacial features seen routinely in the 2,000-mile-long strip found in the 30 to 60 degree band in the chaos terrain of the northern lowland plains. In fact, it is likely that cycles of ebb and flow of those glaciers helped shape this chaos of buttes and mesas and cross-cutting canyons.
This picture however is nowhere near any chaos terrain, or that 2,000 long strip. In fact, it is instead in an area that appears mostly formed by tectonic and volcanic activity, as the overview map below shows.

Today’s blacklisted American: Google scholarship sets racist quotas favoring minorities
Google: dedicated to the new segregation!
“Segregation today, segregation tomorrow, segregation forever!” Tech giant Google has established a discriminatory fellowship program that major universities can participate in that specifically favors some races while barring others.
The Google Ph.D. Fellowship, which gives promising computer scientists nearly $100,000, allows each participating university—a group that includes most elite schools—to nominate four Ph.D. students annually. “If a university chooses to nominate more than two students,” Google says, “the third and fourth nominees must self-identify as a woman, Black / African descent, Hispanic / Latino / Latinx, Indigenous, and/or a person with a disability.”
So no one misunderstands Google’s very specific discriminatory intent, here is the exact quote from its FAQ about the fellowship program:
