The sea of dunes surrounding the Martian north pole

12:25 pm

The sea of dunes surrounding the Martian north pole
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on December 5, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a collection of wormlike dunes located in the giant sea of dunes that surrounds the Martian north pole ice cap.

North is to the top. The season when this picture was taken was northern winter. The Sun is barely above the horizon, only 8 degrees high, and shining from the southeast. Because it is winter it is also dust season, making the atmosphere hazy and thus making the light soft. No distinct shadows, except that the sides of the dunes facing away from the Sun are darkly shadowed.

The consistent orientation of the dunes suggests that the prevailing winds blow from the northeast to create the steep-sided alcoves. The wind however might not be the only factor to form these dunes.

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

Hakuto-R completes five of ten milestones on test flight

7:56 am

Ispace’s private commercial lunar lander, Hakuto-R, has now completed five of the ten milestones the company had established before launch as its goals on this first test flight to the Moon.

The first five milestones completed are:

  • Completion of launch preparations
  • Completion of launch and deployment
  • Establishment of a Steady Operation Status
  • Completion of the first orbital control maneuver
  • Completion of stable deep-space flight operations for one month

The next five milestones involve entering final lunar orbit and landing successfully, the most difficult milestones of all.

SpaceX to build five Starship/Superheavy prototypes in 2023

7:51 am

According to Elon Musk, SpaceX intends to build five Starship/Superheavy prototypes in 2023 for flight testing.

Assuming they can get launch permits, these five rockets should provide the company ample launch testing capability for at least the next two years, especially if it succeeds in landing these units and can consider reusing them in test flights.

At this moment, the launch permits from the federal government appears the main obstacle to getting this heavy lift reusable rocket tested and operational.

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.

Pushback: Southwest flight attendant demands Southwest be sanctioned for violating the terms of her court victory

12:33 pm

Southwest: Enemy to free speech

Bring a gun to a knife fight: Charlene Carter, a flight attendant who had worked at Southwest Airlines for 20 years, was fired in 2017 because she had publicly opposed for religious reasons the use of her union dues to fund pro-abortion protests, and was then reinstated after winning her lawsuit against the airline, is now demanding the court sanction Southwest for violating the terms of her court victory.

In her victory, Southwest was required to reinstate Carter with full benefits, and also issue a statement to its employees that it “may not” engage in religious discrimination. Instead, the airline sent out two notices. The first simply stated “that the Court ordered the company to notify them that it ‘does not’ discriminate on the basis of religion.” The second notice however was worse, as it once again slandered Carter for her religious beliefs.

A Martian river canyon?

A Martian river canyon?
Click for full image.

Today’s cool image highlights the biggest mystery of Mars that has baffled scientists since the first good pictures of its surface were taken in the early 1970s by the Mariner 9 orbiter. The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 24, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a very small segment of the 400-mile-long meandering canyon on Mars called Nigal Vallis. From the Wikipedia page:

The western half of Nirgal Vallis is a branched system, but the eastern half is a tightly sinuous, deeply entrenched valley. Nirgal Vallis ends at Uzboi Vallis. Tributaries are very short and end in steep-walled valley heads, often called “amphitheater-headed valleys.”

We can see one of those short tributaries on the image’s left edge. The overview maps below provide a wider view of this entire canyon.

Starlink service scheduled for South Korea later this year

8:49 am

SpaceX will begin offering Starlink service in South Korea by the spring of this year.

The article, from a South Korea news outlet, is generally negative about Starlink’s possibilities, mostly because its cost is much higher than that already available with coverage that includes 80% of the country. Nonetheless, Starlink will still be an option to those regions not yet served.

SpaceX’s Falcon Heavy successfully launches Space Force satellites

4:06 pm

SpaceX’s Falcon Heavy rocket today successfully launched a Space Force communications satellite plus a secondary military payload.

The two side boosters completed their second flight, landing at Cape Canaveral. The core stage was not recovered, as planned. Actual deployment of the satellites will not occur for another six hours.

At this moment China leads SpaceX 5 to 3 in the 2023 launch race. No one else has as yet launched successfully.

Russia delays three planned lunar probes because of sanctions

10:56 am

The research division that is building Russia’s Luna 26, Luna 27, and Luna 28 probes to the Moon announced today that these missions will likely be delayed up to two years because many needed components are no longer obtainable due to the international sanctions imposed on Russia because of its invasion of the Ukraine.

“Previously, we designed equipment using foreign components that we could buy from our foreign colleagues. Now that the sanctions have been imposed, we will [be switching to] Russian-made components,” Mitrofanov explained. According to him, researchers have to change design solutions amid the Western restrictions.

Some of these components cannot be so easily replaced by Russian versions. Assuming the Ukraine war does not end soon, expect even longer delays for these unmanned lunar missions.

Stratolaunch’s Roc airplane completes 2nd captive-carry test flight

3:48 pm

Stratolaunch’s giant Roc airplane, the largest in existence, successfully completed its second captive-carry test flight, carrying a Talon-A (TA-0) hypersonic test vehicle under its central fuselage during take-off and landing.

The flight set a new duration record lasting a total of six hours and reached a maximum altitude of 22,500 ft., representing another important step forward in the company’s near-term goal of completing separation testing with TA-0. Primary test objectives included flight outside of the local Mojave area for the first time and evaluation of the separation environment. Roc and TA-0’s onboard data systems provide critical information on the aerodynamic loads and moments prior to release of TA-0, helping to ensure safe separation of the vehicle from Roc. The flight team also practiced chase formation and communication sequencing for the upcoming separation test.

The company has a contract with the Air Force to use the operational Talon-1 spacecraft, released from Roc, to do hypersonic test flights, hopefully in the first half of 2023.
