SLS likely facing another launch delay

9:45 am

Engineers for NASA’s SLS rocket have determined that they need to replace the flight controller on one of the engines in the rocket’s core stage, an action that will likely force a delay from the presently scheduled February launch date.

After performing a series of inspections and troubleshooting, engineers determined the best course of action is to replace the engine controller, returning the rocket to full functionality and redundancy while continuing to investigate and identify a root cause. NASA is developing a plan and updated schedule to replace the engine controller while continuing integrated testing and reviewing launch opportunities in March and April.

It appears they hope to make this change-out quickly and only have to delay one or two months, though at the moment it is also unclear this will be possible.

Space Perspectives to build new balloon manufacturing facility in Florida

9:40 am

Capitalism in space: Space Perspectives, the company aiming to fly tourists to the edge of space using high altitude balloons, announced yesterday that is building a balloon manufacturing facility in Titusville, Florida, near its launch facility in the Kennedy Space Center.

Space Perspective, which has already sent up a successful test flight in 2021 and aims to have its first passengers in 2024, announced it would make the $38 million investment that projects the creation of 240 full-time permanent jobs in Brevard County by the end of 2026. The company said the annual average wage would be $80,000, and hiring will continue through 2022.

…The campus and balloon manufacturing facility will be at the Space Coast Airport and Spaceport in Titusville, the updated name of Space Coast Regional Airport in Titusville after it was awarded spaceport status in 2020 by the Federal Aviation.

The company is targeting 2024 for its first commercial tourist flights, with tickets priced at $125K each.

SpaceX in launch of 52 Starlink satellites reuses a 1st stage for the 11th time

9:27 am

Capitalism in space: SpaceX early this morning successfully launched another 52 Starlink satellites into orbit, reusing a Falcon 9 first stage for a record-setting 11th time.

The booster landed successfully on a drone ship in the Pacific, and can now be used again. This success adds weight to the company’s claim a few years ago that the final iteration of the Falcon 9 first stages have the potential for as many as 100 launches. SpaceX has now proven that the stage can fly more than ten times, and still be reused.

This launch also extended SpaceX’s record for the most launches ever by a private company in a single year.

The leaders in the 2021 launch race:

48 China
29 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

China now leads the U.S. 48 to 46 in the national rankings. However, the race to see which country will end up with the most launches is getting tighter. SpaceX has another two launches scheduled in the next three days, with a Virgin Orbit launch following the next day.

This launch was the 125th in 2021, making it the sixth most active year in rocketry since Sputnik. Should those four launches above all succeed, it will be the second most active year, with an outside chance of beating the record of 132 launches from 1975.

Ingenuity successfully completes its 18th flight

1:26 pm

According to a JPL Twitter post today, on December 15th Ingenuity successfully completed its 18th flight, flying 754 feet for just over two minutes.

The plan had been to continue north to cross the rough Seitah region as the helicopter heads back to the spot where Perseverance initially dropped it. Though at this moment no specific information about the flight’s direction or landing place have been revealed, its success suggests it went exactly as planned.

Pushback: NY gym owners will not comply with new mask mandates

12:18 pm

Owners of World Gym Greece
The owners of World Gym Greece will not comply.

Do not comply: The owners of a gym in Rochester, New York, World Gym Greece, have announced that they will not comply with the new mask mandates imposed unilaterally by New York State’s Democratic Party governor, Kathy Hochul.

The owners, Michelle Sember, Ron Sember, and Tim Dougherty, say that they aren’t worried about fines or punishment, as the oppressive edicts of their state and city governments have already been catastrophic. According to Ron Sember,

“The fine is irrelevant at this point. They’ve already destroyed our businesses.”

They have found their membership dropping because people do not want to exercise in a mask. Given a choice between losing more customers or getting punished by the state, they have decided their customers are more important, and are telling everyone to come and work out and throw the mask away.

At the moment the local county government in Rochester is saying it will enforce Hochul’s mandate, while also equivocating on how it will do so.

SpaceX accused of sexual harassment by same “Woke” venue that accused Blue Origin

10:40 am

SpaceX this week was accused of sexual harassment by one named former employee and several anonymous accusers, published in same venue that back in September had published similar anonymous accusations against Blue Origin.

No need to go into the details. The accusations are as light weight and as petty as those against Blue Origin, which the FAA dismissed last week as having no merit because the anonymous accusers refused to identify themselves while the only named accuser’s allegations were deemed meritless. From CNN’s report:

[I]nvestigators had to rely on current and former Blue Origin employees voluntarily coming forward to offer information. But “no technical experts have reached out to us or provided any specific documentation regarding the safety allegations.”

CNN of course spins this in favor of the accusers, claiming that they don’t have any legal whistle-blower protections. I say balderdash. If such people won’t go public, such accusations are worthless. Blue Origin has the right to be faced in public by its accusers.

All in all, the allegations against both companies reek of modern “woke” politics, aiming to smear and slander successful companies because some people are filled with leftist rage and hate and want to destroy anyone who doesn’t obey their every command. I expect the charges against SpaceX will evaporate as well because the anonymous accusers will also refuse to go public, while the actual accusations from the one person willing to go public read like the whining of a mentally unstable person (admitted to in her own statement) who simply can’t handle a modern competitive work environment where you are expected to perform.

SpaceX proposes new launchpads for Starship at Kennedy

10:12 am

Long term Land Use map for Kennedy Space Center
From NASA’s long term road map for Kennedy,

Capitalism in space: SpaceX has submitted a new proposal for building several launchpads at the Kennedy Space Center for its Starship heavy lift rocket, including rebuilding one old pad (LC-39A) and building another at a new site (the never used LC-49).

The project for LC-49 comes in addition to the previously announced work that SpaceX began within the perimeter of Launch Complex 39A, the K Environmental Program Office said. In September 2019, an environmental assessment was completed and a finding of “no significant impact” was issued.

Musk confirmed via Twitter on Dec. 3 that construction of SpaceX’s Starship orbital launch pad at LC-39A was underway. “Construction of Starship orbital launch pad at the Cape has begun”.

The KEP [Kennedy Environmental Program] office noted that this new proposed expansion would allow for not only redundancy with launches of Starship, but also “allow SpaceX to increase the flight rate of Starship and minimize potential disruptions to Falcon, Falcon Heavy and Dragon missions at LC-39A.”

LC-49 is a 175 acre area just north of LC-39B, the launchpad NASA plans to use for its SLS rocket.

It also appears that SpaceX plans on creating a new Starship orbital launchpad at LC-39A that will not impact the use of that site by Falcon 9 and Falcon Heavy, though in the long run launches of those latter rockets will decrease as Starship becomes operational.

All these plans will need a full environmental assessment, but according to the article at the link, the process will be different than at Boca Chica in Texas.

The [environmental assessment]process likely won’t involve live discussions with the public, according to [Don Dankert, the technical lead for the Kennedy Environmental Planning Office], but the public will get comparable information, like with an EIS [Environmental Impact Statement]. “We will put out the same information,” Dankert said. “We’ll put out an informational packet with a .PDF chart, a description of the project and instructions on how to provide comments back to us and SpaceX.”

Engler said there may also be some lessons learned from the process of getting the launch facilities at Starbase approved for an orbital launch, but how that crossover would work has yet to be determined.

Sounds to me that this is all a pointless paperwork dance. The construction will be approved, no matter what, because Florida and Cape Canaveral desperately wants this new business and the jobs and tax dollars it will bring to the state.

Perseverance scientists: First volcanics then water in Jezero Crater

9:45 am

On December 15th the Perseverance science team presented a summary of the rover’s first nine months exploring the floor of Jezero Crater, finding evidence first of volcanic lava activity followed by several periods where water covered the these same rocks.

“These rocks that we originally thought might be sedimentary rocks, these are in fact igneous [volcanic] rocks,” said Kelsey Moore at the California Institute of Technology (Caltech). “And even more excitingly, they’re not just igneous rocks – there’s more history to the story.”

The analysis of the rocks’ compositions revealed minerals that are generally produced by interactions between water and rock, as well as traces of two different salts that were probably left behind as salty water flowed through the cracks and pores in the volcanic rock.

The variety of minerals indicates that these rocks were probably underwater at least twice. “Two different types of liquid with two different types of chemistries points towards two different episodes of liquid water interaction,” said Eva Scheller, also at Caltech.

It seems strange that the scientists were surprised that Jezero Crater has a history of volcanic activity. Most craters when formed have what is called impact melt in their crater interior. The impact not only carves out the crater, the heat of impact melts the rock. Possibly the scientists expected such impact melt to be well buried and not accessible to Perseverance.

Regardless, this data will be used as the baseline for documenting the geological history of this region on Mars as Perseverance continues its journey across the floor of the crater, up onto the delta, and then out of the crater into the uplands beyond.

Cracking glaciers on Mars

Cracking glaciers on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was released today as the picture of the day for the high resolution camera on Mars Reconnaissance Orbiter (MRO). Located in the 2,000 long northern mid-latitude strip that I dub Mars’ glacier country, it shows many of the numerous glacial features that are routinely found in images taken in this region. According to Dan Berman, senior scientist at the Planetary Science Institute in Arizona, who wrote the caption,

This observation shows a lobe-shaped debris apron emanating from a massif (shown in the upper left of the image) in the Protonilus Mensae region in the Northern Hemisphere of Mars. These aprons are composed of nearly pure water ice with a layer of debris on the surface protecting the ice from sublimation (going directly from a solid to gaseous state). This image shows different terrain types on the apron that indicate the presence and flow of ice, from smoother polygonal terrain closer to the massif, to rougher, patterned ground commonly called “brain terrain.” Also visible on the apron are a series of linear pits.

Protonilus Mensae is the central mensae region in that mid-latitude strip of glaciers.The overview map below shows the location of this photo in that region. Also below is a close-up of the linear pits and cracked terrain surrounding that oblong mound, as indicated by the white rectangle.
