Another Starhip update: Static fire test today for #11

9:02 am

Link here. If the static fire goes well, the test flight for Starship prototype #11 should occur in the next few days, possibly as soon as tomorrow.

The article at the link also reviews the possible testing schedule for future prototypes. The next Starship prototype being prepared for flight, #15, will likely not fly next. Instead, it appears that SpaceX is gearing up to first begin tanking tests on its first Super Heavy prototype.

All could change of course depending on tests and flights and construction.

Clouds over Gale Crater

Clouds over Gale Crater

Cool image time! In today’s download of new images from Curiosity was a large number looking at the sky. by one of the rover’s navigation cameras. As noted in the science team’s most recent update, their aim was to “watch for clouds in the sky at twilight.”

They were apparently very successful. The picture to the right, reduced to post here, is one example. The other pictures show these clouds and other clouds as they change over time.

I don’t have much more to add, other than to say it is quite breath-taking to be able to sit here on Earth and routinely gaze at the weather on Mars.

UPDATE: I do have one more thing to say. If you have any skills at programming and want to figure out how to process the raw images from Curiosity and Perseverance to bring out their color, you might find the video at this link of interest: How Can You Color Process Mars Rover’s Images In DaVinci Resolve?

I am not a computer programming geek, so some of its details went over my head. Nonetheless, it opened a window into the photo-engineering used to turn the rovers’ black-and-white digital data into color.

Glynn Lunney, R.I.P

10:18 am

NASA flight director Glynn Lunney has passed away at the age of 84.

He not only was one of the flight directors in Houston that helped get astronauts to the Moon in 1969, he was also instrumental in getting the crew of Apollo 13 back home when their service module failed in 1970.

Lunney and his team were just about to come on console for the evening shift on April 13, 1970, when the Apollo 13 crew radioed, “Houston, we’ve had a problem.”

“For me, I felt that the Black Team shift immediately after the explosion and for the next 14 hours was the best piece of operations work I ever did or could hope to do,” Lunney said in his oral history. “It posed a continuous demand for the best decisions often without hard data and mostly on the basis of judgment, in the face of the most severe in-flight emergency faced thus far in manned spaceflight.”

“We built a quarter-million mile space highway, paved by one decision, one choice, and one innovation at a time — repeated constantly over almost four days to bring the crew safely home. This space highway guided the crippled ship back to planet Earth, where people from all continents were bonded in support of these three explorers-in-peril,” he said. “It was an inspiring and emotional feeling, reminding us once again of our common humanity. I have always been so very proud to have been part of this Apollo 13 team, delivering our best when it was really needed.”

He had been part of NASA when it was young (as he was) and honest and dedicated to accomplishing its goals fast and efficiently and — most significantly — with courage. May he rest in peace.

Volcanic badlands on Mars

Volcanic badlands on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on January 29, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a particularly ugly region of rough terrain located about 900 miles to the southwest of the giant volcano Arsia Mons, the southernmost of the chain of three giant volcanoes between Olympus Mons and Valles Marineris. The picture sits inside the floor of a very old and degraded 185-mile-wide crater dubbed Koval’sky.

The section I cropped out was picked at random, because the entire full image looked like this. Though only a handful of images have been taken of the floor of Koval’sky Crater by MRO’s high resolution camera, all show similar rough terrain. In June 2017 the MRO science team posted one of those few such photos with the following caption:

Today’s blacklisted Americans: Virginia teachers & parents who oppose teaching children that whites are evil and minorities cannot be racist

1:15 pm

Today's modern witch hunt
Burning witches: what the modern left wants to do to its opponents.

They’re coming for you next: In an effort to slander their opponents and prevent them from shutting down the use of Critical Race Theory (CRT) with its blatant anti-white propaganda, administrators, teachers, and some parents in Loudon County, Virginia, began compiling an enemies list of anti-CRT parents and teachers to blacklist those individuals and silence them.

Members of a 624-member private Facebook group called “Anti-Racist Parents of Loudoun County” named parents and plotted fundraising and other offline work. Some used pseudonyms, but The Daily Wire has identified them as a who’s who of the affluent jurisdiction outside D.C., including school staff and elected officials.

The sheriff’s criminal investigations division is reviewing the matter — but the group’s activities might be no surprise to top law enforcement because the county’s prosecutor, narrowly elected with the help of $845,000 in cash from George Soros, appears to be a member of the Facebook group.

Secret communications reviewed by The Daily Wire do not offer any evidence of racism by the group’s targets. Their opponents were apparently those who objected to, sought to debate, or were even simply “neutral” about “critical race theory,” a radical philosophy opposed by many liberals and conservatives but increasingly embraced by governments.

The article is gentle about how it describes “critical race theory,” which is a wholly bigoted program designed to generate hate between whites and all minorities as it demonizes whites as evil and blesses all minorities as perfectly pure and good.

One email from the Facebook group outlined how the supporters of this bigoted race theory program planned to use that enemies list.

Update on SpaceX’s Super Heavy booster

9:55 am

Capitalism in space: According to this update on SpaceX’s Super Heavy booster, the first prototype is now stacked as two complete tank sections that only need to be welded together.

While a good amount of work still remains to weld the two halves together and connect their preinstalled plumbing and avionics runs, those tasks are largely marginal and will tweak the massive steel tower that’s now firmly in one piece. Comprised of 36 of the steel rings also used to assemble Starships, the first Super Heavy prototype – serial number BN1 – will stand roughly 67 meters (220 ft) tall from the top of its uppermost ring to the tail of its soon-to-be-installed Raptor engines.

At that height, Super Heavy BN1 is just 3 meters (~10 ft) shorter than an entire two-stage Falcon 9 or Falcon Heavy rocket – the second and third tallest operational rockets today. Of course, Super Heavy is just a booster and SpaceX says the rocket will stand at least 120m (~395 ft) tall with a Starship upper stage and spacecraft installed on top, easily making it the tallest (and likely heaviest) launch vehicle ever assembled.

The report also adds SpaceX’s confirmation that this prototype will never fly, but will be used solely for ground tests. It is the second prototype that will do the first short test hops, hopefully sometime this summer.

SpaceX & NASA agree to better coordinate their satellite constellations to avoid collisions

9:49 am

NASA announced yesterday that it has signed an agreement with SpaceX to better coordinate and share information about their their satellite constellations in order to avoid collisions and launch conflicts.

SpaceX has agreed its Starlink satellites will autonomously or manually maneuver to ensure the missions of NASA science satellites and other assets can operate uninterrupted from a collision avoidance perspective. Unless otherwise informed by SpaceX, NASA has agreed to not maneuver its assets in the event of a potential conjunction to ensure the parties do not inadvertently maneuver into one another.

Makes great sense. Not only will this help avoid damage to satellites from both entities, it commits NASA’s support of SpaceX’s Starlink.

NASA confident Webb will launch in October

9:36 am

In a briefing held yesterday, NASA officials — in summarizing the status of the James Webb Space Telescope — stated they were presently confident that its launch will take place in October this year, as presently planned.

[Eric Smith, JWST program scientist> said the program is dealing with one new technical issue. Two communications transponders suffered separate problems during testing in January. Engineers have tracked down the problems with the two units and started repairs this week. “Those boxes will be back in time for us to make our planned shipping date,” he said.

That issue, he acknowledged, will use some of the remaining schedule margin. “The plan right now is that we’ll get them back in time so that we don’t have to use all of it,” he said. “That’s the main thing that we’re watching regarding the margin.”

If launched in October, Webb will only be a decade behind schedule and a mere 20 times over budget, having been initially proposed to launch in 2011 for a cost of $500 million. Instead, it will cost about $10 billion.

The article also notes that the Biden administration might change the telescope’s name because Webb as a bureaucrat early in his career apparently publicly opposed homosexual rights. Such opinions can no longer be allowed, and anyone who has them must be blackballed as quickly as possible.

No matter. Webb was merely NASA’s administrator through almost its entire first decade, leading the agency in its triumph over the Soviets in the race to the Moon. Such achievements cannot be honored as they illustrate the past greatness of America. Moreover, Webb was a white man, and this makes him totally unqualified to receive any laurels. Today’s modern America hates itself and all white men.

The article also notes a variety of issues that will cause more delays of the new big astronomy boondoggle at NASA, the Roman Space Telescope. They say its launch will likely be delayed to 2026 because of the Wuhan flu panic. I predict this is only a foretaste. Expect many more delays and budget overruns, probably pushing its launch into the 2030s.

But no matter. What is really important is that this new boondoggle is named for a woman!
