JPL to lay off 8% of its work force plus 40 contractors

11:34 pm

Claiming the uncertainty of its federal budget allocation due to Congress’s inability to pass a new budget, the Jet Propulsion Lab (JPL) earlier today announced it was laying off 8% of its work force, 530 employees, plus 40 contractors.

In a memo to JPL staff Feb. 6, [director Laurie] Leshin said that a lack of a final 2024 appropriations bill — NASA is operating on a CR [continuing resolution] that runs until March 8 — forced the layoffs after taking other measures such as a hiring freeze and reductions in MSR [Mars Sample Return] contracts and other spending, as well as the earlier contractor layoffs. “So in the absence of an appropriation, and as much as we wish we didn’t need to take this action, we must now move forward to protect against even deeper cuts later were we to wait,” she wrote.

Uncertainty about how the Mars Sample Return project should be designed and built had caused Congress to express doubts about the project, with the Senate suggesting major cuts. NASA responded by loudly pausing the project and suggesting its own cuts. JPL has now followed up with these layoffs. Both have I think done so as a lobbying tactic, and as expected in this game of budget lobbying these actions have caused many legislators to scream in horror: “We really didn’t mean it! We really don’t want to cut anything!”

Expect our bankrupt Congress to fold and provide NASA and JPL the blank check it wants to fly a Mars mission that will cost billions, be years late, and likely be beaten to Mars by SpaceX’s Starship (which could do the job for a tenth the cost).

Pushback: Help send 9-year-old KC Chiefs fan, slandered as bigot by media, to Super Bowl

3:17 pm

on television following the slander. Click for video.

Bring a gun to a knife fight: A fundraiser has been started to send 9-year-old KC Chiefs fan, Holden Armenta, to the Super Bowl, in defiant response to the ugly effort by one racist reporter, Carron Phillips, and his media outlet, Deadspin, to slander the boy as a bigot because he attended a game wearing facepaint with the red and black colors of the Chiefs.

Phillips had unjustly accused the child of wearing blackface, and Deadspin helped Phillips push this lie by printing a picture that only showed the black side of Armenta’s face. A head-on shot showed his facepaint had nothing to do with blackface, but was a typical example of what many football fans do, paint their faces with the colors of their team. The right side of the boy’s face was painted black, the left side red.

What made the slander even more egregious is that Holden is an American Indian, with his grandfather, Raul Armenta, on the board of the Chumash Tribe in Santa Ynez, California.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Curiosity’s damaged wheels continue to appear stable despite the rough Martian terrain

12:27 pm

A new look at Curiosity's worst wheel
To see the original images, go here and here.

The rover Curiosity on Mars has for more than two years been traveling across a very rocky and rough terrain as it climbs higher and higher on Mount Sharp inside Gale Crater. Since the rover’s wheels experienced far more damage than expected early in its mission, when it was on the floor of the crater where the terrain was not as severe, engineers have adopted a whole range of techniques to try to reduce any further damage.

First, they increased the safety margins on the software that guides Curiosity. It picks its way very carefully through the rocks, and stops immediately if it finds itself crossing terrain that is too rough.

Second, the science team does a photo survey of the wheels after every kilometer of travel. The two pictures to the right compare the damage on the rover’s most damaged wheel, with an image from the previous survey on top and the most recent image, taken yesterday, on the bottom. I have numbered the same treads, called grousers, in the two images to make it easier to compare them.

As you can see, it does not appear as if the damage has increased in the 210 sols or seven months of travel since the last survey. This wheel looks bad, but it is the worst wheel on the rover, and the strategies that the engineering team adopted years ago to reduce further damage continue to work, even as Curiosity traverses some very rough ground.

The software requires the rover to travel shorter distances in each drive when the ground is this rough, but the consequence is that it will last much longer, and thus have a better chance of reaching higher elevations on Mount Sharp.

SpaceX’s revenue estimate for 2024 is $13.3 billion

10:56 am

According to an independent analysis of SpaceX’s announced launch plans for 2024, the company’s revenue in 2024 is predicted to be somewhere around $13.3 billion, including earnings from Starlink subscribers.

This independent estimate is less than SpaceX’s own projection of $15 billion, but what is important is that the revenue in 2024 equals approximately the total amount of investment capital that SpaceX has raised for Starship/Superheavy and Starlink. Add to this the estimated revenues from 2023, $8 billion, and it appears SpaceX is in a very healthy position to complete the construction of Starship and begin flying it regularly for profit.

Perseverance snaps its first picture of grounded Ingenuity

10:25 am

Ingenuity on dune, as seen by Perseverance on February 4, 2024
Click for original image.

Perseverance on February 4, 2024 finally moved into a position where it was close enough to take its first picture of the now grounded Ingenuity helicopter. That picture, cropped, reduced, and enhanced to post here, is to the right, taken by the rover’s left high resolution camera. You can see Ingenuity sitting on the slope of a dune near the upper right.

The overview map above provides the context. The green dot marks Ingenuity’s final resting spot. The blue dot marks Perseverance’s present location, with the yellow lines indicating approximately the area covered by the photo.

Whether the rover is now close enough to get good imagery for a final engineering test of Ingenuity — where its rotors will be rotated and shifted slowly to determine the extent of the propeller damage — is not clear. Perseverance could move much closer, but its science team might not want to cross these dunes out of fear the rover would get stuck. They might move forward a few more feet, to the top of the south bank of Neretva Vallis, before doing that test.

Juno completes its closest approach of the Jupiter moon Io

9:53 am

Io on February 3, 2024
Click for full image.

The Jupiter orbiter Juno successfully completed its 58th close fly-by of the gas giant, during which it also made its closest approach to the volcanic moon Io, zipping past at a distance of 932 miles. The image of Io to the right, cropped and reduced to post here, was taken at that closest Io approach, and shows a mountain on the horizon as well as a large shield volcano in the center (the dark splotch), with a major lava flow to the south. The picture was processed by citizen scientist Brian Swift.

Another image, processed by Björn Jónsson, shows the differences at one volcano dubbed Loki between the December 30, 2023 and the February 3, 2024 flybys. It appears that the brightness of the apron of lava that surrounds the volcano changes significantly depending on the lighting and the angle of view. In December it was almost black. In February it was greyish silver, almost shiny.

Another image, processed by Andrea Luck, captured faint eruption plumes on Io’s edge, caused by an ongoing eruption just beyond the horizon.

Juno still has four more flybys of Io coming up, but none will be as close as the February 3rd approach.

A pin falls off Virgin Galactic’s mother ship during most recent passenger flight

9:14 am

Virgin Galactic has notified the FAA that a pin fell off its Eve mother ship, carrying its SpaceShipTwo Unity suborbital spacecraft, during most recent passenger flight on January 26, 2024.

Virgin Galactic said the alignment pin fell from its VMS Eve mothership aircraft, the plane that carries VSS Unity aloft. The pin is used to ensure Unity is aligned to Eve when mated during preflight preparations. After takeoff, the pin helps transfer drag loads from Unity into the pylon and center wing section of the aircraft. The alignment pin detached after Unity separated from Eve, although the company did not state how long afterwards the pin came off. The pin, along with a separate shear pin fitting assembly, do not play a role in flight activities after the release of the spaceplane.

The FAA states it will do an investigation before permitting more flights, but we know from a recent GAO report that it does no such thing. It simply observes the investigation by the company involved, and then rubber stamps it afterward. Nor is this wrong, as no one at the FAA is qualified to do such investigations, unlike the engineers at the company.

The investigation however might impact the next flight. The company has said it intends to end flights using Unity after then next three, and then stand down as it replaces it with its next generation spacecraft. This incident might force that stand-down to occur sooner.

Weather stops everything by SpaceX in the last 24 hours

9:00 am

SpaceX found itself stymied in the past 24 hours due to poor weather conditions on both coasts, with two launches and the return of a Dragon capsule from space all scrubbed.

First a Falcon 9 launch from Vandenberg of 22 Starlink satellites was scrubbed, the launch pushed back from yesterday to tonight at 5.39 pm (Pacific).

Then a launch of a NASA climate satellite on a Falcon 9 rocket from Cape Canaveral was scrubbed shortly thereafter, the launch rescheduled for 1:33 am (Eastern) tonight.

Finally, the return of Axiom’s Ax-3 commercial passenger flight to ISS was scrubbed today because of poor weather conditions.

NASA, Axiom Space, and SpaceX are standing down from the Tuesday, Feb. 6, undocking opportunity of Axiom Mission 3 from the International Space Station. Mission teams will continue to review weather conditions off the coast of Florida, which currently are not favorable for return, and set a new target opportunity for space station departure and splashdown of the Dragon spacecraft and Axiom crew members.

The undocking is now tentatively set for tomorrow morning, but this remains unconfirmed. The three passengers and the Axiom commander have so far spent 18 days in orbit. The original plan was for a 14 day mission, most of which to be spent on ISS, but weather can always extend such plans.

The launch scrubs illustrate the challenge SpaceX faces in reaching its stated goal of 150 launches in 2024. It appears the company is now capable of technically meeting that goal. To do it however it needs to launch almost every other day, and weather simply might not allow a pace like this during some parts of the year in both Florida and California. Whether the company can make-up for these delays with multiple daily launches at other times remains unknown. If it does, it will be another feather in the cap for SpaceX.

Ed Wynn, Julie Andres, Dick Van Dyke – I Love to Laugh

6:01 pm

An evening pause: From the 1964 film, Mary Poppins. I post it to celebrate my birthday. I saw this movie in the theater that year, as an eleven-year-old, and its optimistic and hopeful look at existence has never left me, even now in these dark times. If only today’s adults would focus on teaching these same positive and hopeful lessons to their own children.
