Two smallsat orbiters to launch in ’24 to study Martian upper atmosphere

11:53 am

NASA has picked a twin orbiter mission being built by a partnership of the University of California-Berkeley and the private rocket company Rocket Lab to place two smallsats in orbit around Mars to study how the harsh environment of space might be causing the red planet to lose its atmosphere.

The entire project is dubbed ESCAPADE (an insanely contrived acronym) but the two smallsats have been dubbed “Blue” and “Gold.”

The mission builds on decades of experience at SSL in building satellite instruments and fleets of spacecraft to explore regions around Earth, the moon and Mars, specializing in magnetic field interactions with the wind of particles from the sun. Each of the two satellites, named after UC Berkeley’s school colors, will carry instruments built at SSL to measure the flow of high energy electrons and ionized oxygen and carbon dioxide molecules escaping from Mars, magnetic field detectors built at UCLA and a probe to measure slower or thermal ions built at Embry-Riddle Aeronautical University in Daytona Beach, Florida.

With twin satellites, it is possible to measure conditions simultaneously at two places around the planet, Lillis said, allowing scientists to connect plasma conditions at one site to the escaping ion flux at another. Over the course of the mission, the two satellites will change positions to map the upper atmosphere and magnetosphere of nearly the entire planet from an altitude of between 150 and 10,000 kilometers.

Maybe the most important aspect of this mission however is not what it will learn at Mars, but how it is being financed and built. NASA is only paying about $80 million, a tiny amount compared to most past unmanned planetary probes. The university in turn is buying Rocket Lab’s Photon satellite structure rather than building the satellites from scratch. It will configure the instruments to fit into that ready made satellite body, thus saving time and money.

By doing it this way NASA and the planetary science community is increasingly relying on private companies to provide them their planetary probes, rather than building such things by hand themselves, at much greater cost. The result is a growing and thriving private commercial sector that owns and builds its own planetary probes, for profit.

Cool image time! The photo above, taken on August 22, 2021 by Curiosity’s left navigation camera and reduced to post here, looks ahead at the rover’s upcoming mountainous goals. The overview map to the right shows the area covered by this image by the yellow lines. The dotted red line indicates the rover’s original planned route, with the white dotted line its actual path of travel.

The cliff ahead is about 400-500 feet away. The top of this cliff is the Greenheugh Pediment, its blocky top geological layer visible as the dark cap at the top of the cliff face. Back in March 2020 Curiosity had climbed up to view across this pediment, from a point to the northwest and off the overview map to the left. (Go to this link to see what the view was like from there.) Since then the science team has had the rover travel quite a distance, to circle around to now approach the pediment from the east.

The white box marks the area covered by a close-up high resolution mast camera image, shown below.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Update on Starship/Superheavy preparations for orbital test flight

9:15 am

Starship prototype #20 being prepped
Screen capture from Labpadre live stream, available here.

Link here. In sum it appears that SpaceX is getting very close to launch, with the permit approval of the FAA increasingly becoming the biggest obstacle to progress.

Although the completion of all of this testing could take a long time, in Elon Musk’s mind, the path to returning B4 and S20 to being an integrated stack could be during this month.

A week ago, Musk tweeted that the “first orbital stack of Starship should be ready for flight in a few weeks, pending only regulatory approval.” Ultimately, once the vehicle is in its launch configuration, there will be a lengthy process of passing the aforementioned regulatory approval, with an environmental public comment period triggered ahead of launch. This has to be completed before the launch license can be granted by the Federal Aviation Administration (FAA).

The screen capture above shows Starship prototype #20 sitting on the suborbital flight test pad, as workers on cherry-pickers work on its exterior. The orange, green, and white tiles are likely tile locations still needing some level of installation work.

Based on SpaceX’s normal pace of operations, the engine testing for both Starship and Superheavy will take several weeks, once both are ready for such testing. While Starship appears just about ready, Superheavy apparently needs more work. When SpaceX stacked both together on the orbital launchpad several weeks ago, it suggested both were closer to launch than they were. Their present status suggests engine testing will likely begin in September, with Starship at the beginning of the month and Superheavy at the end of the month. That would make a launch possible sometime in late October, assuming the federal government doesn’t decide to shut this entire operation down by refusing to issue a permit.

Asteroid discovered with shortest orbit yet

8:55 am

Astroid's orbit
Click for full image.

Astronomers have discovered an asteroid that circles the Sun with the shortest orbit yet found, flying mostly inside the orbit of Mercury.

The illustration to the right shows the asteroids orbit, which is also tilted 32 degrees from the plane of the solar system.

The orbit of the approximately 1-kilometer-diameter asteroid takes it as close as 20 million kilometers (12 million miles or 0.13 au), from the Sun every 113 days. Asteroid 2021 PH27, revealed in images acquired during twilight, also has the smallest mean distance (semi-major axis) of any known asteroid in our Solar System — only Mercury has a shorter period and smaller semi-major axis. The asteroid is so close to the Sun’s massive gravitational field, it experiences the largest general relativistic effects of any known Solar System object.

Relatively few asteroids have been found with orbits shorter than Earth’s, because to find them astronomers have to turn their telescopes sunward, where viewing is limited to the early evening or early morning. Few space-based telescopes in all wavelengths also don’t look this way much, because of the risk of damage from the intense sunlight.

It is thus unknown exactly how many asteroids exist with similar orbits. There may be many, with many having short eccentric orbits, similar to comets, that extend out to Earth’s orbit and thus pose a risk. Or there may be few, since such orbits so close to the Sun are likely to cause the asteroid’s break-up and destruction over time.

Knowing how many of course is important, in order to obtain a full census of those asteroids in the solar system that might hit the Earth. To get it will likely require placing a probe designed to look for them.

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.

Russia launches another 34 OneWeb satellites

12:38 am

Russia today put another 34 OneWeb satellites into orbit, using its Soyuz-2 rocket.

OneWeb now has 288 satellites in orbit, out of the planned 648. At present the constellation is able to provide service to customers in latitudes north of 50 degrees. Though SpaceX’s Starlink constellation is also offering service to customers in the same northern latitudes, the two companies service different customer bases, with OneWeb aimed at big business and government operations and Starlink aimed at individual residential customers.

The leaders in the 2021 launch race:

27 China
20 SpaceX
13 Russia
4 Northrop Grumman.

The U.S. still leads China 31 to 27 in the national rankings.

Trump says he “single-handedly” decided to move Space Force command from Colorado to Alabama

9:19 am

On Friday former President Donald Trump stated that it was his decision to put the headquarters of the new Space Force in Alabama, not in Colorado where most military related space operations have been located for decades.

“Space Force — I sent to Alabama,” Trump said. “I hope you know that. (They) said they were looking for a home and I single-handedly said, ‘Let’s go to Alabama.’ They wanted it. I said, ‘Let’s go to Alabama. I love Alabama.’”

U.S. Rep. Doug Lamborn, a Republican who represents Colorado Springs, said Trump’s remarks were “an admission” that the headquarters move “was based solely on politics and personal preference — not the Air Force’s basing criteria or national security.”

When this decision was announced in January, I then believed porkmeister Senator Richard Shelby (R-Alabama) had forced it through, but it appears now that is wrong. It was Trump, but still for reasons of pork.

This was a bad decision, one that from the beginning was going to have both practical and political opposition. For practical reasons Colorado always made better sense as Space Force headquarters because it would require less relocation of assets. For political reasons it was flying in the face of a lot of well-established vested interests in Colorado.

Trump’s admission yesterday will likely provide the final bit of ammunition needed by Colorado politicians to get it overturned.

Russia delays launch of next unmanned lunar probe

9:04 am

According to a story in Russia’s state-run press, Roscosmos has decided to delay the launch of its Luna-25 lander from October 2021 to May 2022.

The story gave no reason for the delay.

Luna-25 would be the first Russian lunar probe since the 1970s, and is supposed to be that country’s first probe in a partnership with China to establish a manned lunar base by the 2030s.

Want to bet the Russian contribute to this project will be repeatedly delayed, and will also likely be disappointing? That has been the track record of Roscosmos for the past two decades (like all 21st century government projects). This first delay signals many more to come.

I am not saying Russia will fail to launch anything. What I am saying is that everyone should reserve a large store of skepticism about any promises Russia’s makes.

Top engineers and managers fleeing Blue Origin

3:58 pm

According to this story today, Blue Origin this summer lost at least sixteen top management and engineering employees, all leaving in a very short time.

At least 16 key leaders and senior engineers have left Blue Origin this summer, CNBC has learned, with many moving on in the weeks after Bezos’ spaceflight.

…Others quietly updated their LinkedIn pages over the past few weeks. Each unannounced departure was confirmed to CNBC by people familiar with the matter. Those departures include: New Shepard senior vice president Steve Bennett, chief of mission assurance Jeff Ashby (who retired), national security sales director Scott Jacobs, New Glenn senior director Bob Ess, New Glenn senior finance manager Bill Scammell, senior manager of production testing Christopher Payne, New Shepard technical project manager Nate Chapman, senior propulsion design engineer Dave Sanderson, senior HLS human factors engineer Rachel Forman, BE-4 controller lead integration and testing engineer Jack Nelson, New Shepard lead avionics software engineer Huong Vo, BE-7 avionics hardware engineer Aaron Wang, propulsion engineer Rex Gu, and rocket engine development engineer Gerry Hudak.

Those who announced they were leaving Blue Origin did not specify why, but frustration with executive management and a slow, bureaucratic structure is often cited in employee reviews on job site Glassdoor.

There is another possibility that would be more hopeful. It could be that Jeff Bezos is shaking up the company because of its poor accomplishments during the past four years, since CEO Bob Smith was hired.

That Smith however is still there makes this guess unlikely. The article also notes that Smith’s approval among Blue Origin employees is abysmal, with only 15% approving his management, when compared to high numbers given to the management leaders at SpaceX and ULA.

Thus, this exodus is more likely a sign that that the rats are fleeing what they see as a sinking ship.

It would be a mistake to dismiss Blue Origin however. The company is swimming in dough because of Bezos’ deep pockets, and he is free to do what he thinks must be done to fix things. Under such conditions it is very unlikely Blue Origin will disappear. More likely Bezos will straighten things out, though the company now has to play big catch up, not only against SpaceX but also against the fleet of new orbital rocket companies about to come on line — all doing so ahead of Blue Origin.

There is also the possibility that this story has got its facts wrong. It makes a very big error near the beginning, claiming that former SpaceX engineer Lauren Lyons had left Blue Origin to join SpaceX, when she had actually left SpaceX to take a big promotion at Firefly. My mistake. Lyons had moved from SpaceX to Blue Origin. This job change was leaving Blue Origin to go to Firefly.

New cracks across old Martian lava flows

1:03 pm

New cracks across an old lava flow
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on June 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It captures one of the many deep straight fissure canyons that make up the feature dubbed Cerberus Fossae in the center of Mars’ volcano country.

The crack is called a graben, and happens when the ground is either stretched from pressure from below, or when two adjacent large blocks of material move sideways relative to each other.

What makes this particular graben interesting are two features. First, the overlapping break suggests something complex took place at this spot when the crack separated. Second, the crack cut across the foot of an older frozen lava flow, meaning it has to be younger than that flow.

The overview map below provides a clue when that lava flow might have occurred, while also suggesting this crack in Cerberus Fossae might be much younger than expected.

Today’s blacklisted American: Unvaccinated students at Quinnipac University to be punished

11:53 am

Coming to your town in America soon!
Rounding up the unclean unvaccinated: coming soon to America.

Genocide is coming: Quinnipac University in Connecticut, having reimposed an indoor mask requirement, has now announced that it will fine and punish any students who do not provide proof that they have either been vaccinated against COVID or have a proper exemption.

Quinnipiac students may be fined up to $200 per week eventually until they prove their vaccination status. Fines for students who don’t supply vaccination proof will begin at $100 per week for the first two weeks. The penalty will increase by increments of $25 every two weeks until a max fine of $200 per week.

Currently non-complying students can avoid the fines if they show the proper documentation by Sept. 14. If they fail to meet the directive by then, they will lose access to the campus internet network.

No longer is the left screaming “My body! My choice!” Then that mantra for abortion worked to garner it political support from naive followers. Now the mantra is “Your body is ours! Let us do to it what we want or we will oppress you!”

It is a very short leap from merely punishing those who refuse a vaccine to rounding them up in camps to isolate them from the rest of society. From there, it is an even shorter leap to imposing mass executions to keep society clean from such unpure individuals.
