Click for full resolution. The highest mountain on the right is about 450 feet high.

Even as the rover Perseverance is beginning its first science campaign on the floor of Jezero Crater, the rover Curiosity about 3,000 miles to the east has begun its climb into the mountains of Mars that surround the central peak of Gale Crater, Mount Sharp.

The mosaic above, made from two images taken by the rover’s right navigation camera (here and here), shows what Curiosity sees ahead. Since my last update on June 4th describing Curiosity’s future travels, the rover’s science team has pushed forward directly uphill towards the entrance to the canyon Gediz Vallis, visible as the gap between the mountains to the right and left in the above mosaic.

The overview map below shows the rover’s approximate present position, with the yellow lines indicating what the above photo is looking at.

FAA, local Texas DA, and environmental group out to get SpaceX and Starship

10:16 am

Two news articles today suggest that a number of government officials, environmental groups, and some news media are beginning to team up to damage SpaceX and hinder its ability to succeed.

First we have this Verge article, aimed at suggesting that SpaceX violated its launch license and ignored FAA warnings not to launch during a December 9th test flight of the eighth Starship prototype.

Minutes before liftoff, Elon Musk’s SpaceX ignored at least two warnings from the Federal Aviation Administration that launching its first high-altitude Starship prototype last December would violate the company’s launch license, confidential documents and letters obtained by The Verge show. And while SpaceX was under investigation, it told the FAA that the agency’s software was a “source of frustration” that has been “shown to be inaccurate at times or overly conservative,” according to the documents.

The article generally takes the side of the FAA, suggesting that SpaceX was lax and nonchalant about the risks relating to weather and launch conditions, and proceeded with its launch even though FAA officials thought it unsafe. It also quotes Wayne Monteith, the head of the FAA’s space division, blasting SpaceX for showing “a concerning lack of operational control and process discipline that is inconsistent with a strong safety culture,” claiming that FAA software showed a risk to nearby buildings and homes should the rocket explode in the air.

However, buried far down in the article it also notes,

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

Another smallsat startup announces plans to build its own orbital space tug

9:34 am

Capitalism in space: The smallsat launch startup Launcher announced yesterday that it in addition to developing its own rocket, it plans to build an orbital space tug that can be used both by it and on other smallsat satellites.

Launcher, which announced a $11.7 million funding round June 2, said its Orbiter tug will be able to carry up to 150 kilograms of payload, either in the form of 90 units worth of cubesat deployers or larger satellites using standard smallsat separation systems. Orbiter can also accommodate hosted payloads with power, communications, and other capabilities. Orbiter is equipped with a chemical propulsion system using ethylene and nitrous oxide propellants. The vehicle will initially provide 500 meters per second of delta-v, or change in velocity, but that can be increased by adding more propellant tanks.

Orbiter is intended for use on Launcher Light, the small launch vehicle the company is developing, with a first launch projected in 2024. However, Orbiter is also capable of flying on other launch vehicles using an ESPA Grande adapter ring. Orbiter’s first mission is scheduled for October 2022, when it will fly on a SpaceX Falcon 9 rideshare mission.

That makes about four companies, Launcher, Momentus, Spaceflight, and D-Orbit, building space tugs for use on smallsats. Some will be on board a Falcon 9 launch set for later this month.

Some Starlink units shut down if weather gets too hot

9:27 am

Capitalism in space: Some users of SpaceX’s Starlink internet dishes have found that the units shut down if the local weather gets too hot.

The units presently being distributed to customers are beta units, designed to test the system before SpaceX rolls out full commercial availability, so finding such issues is not unexpected. According to one engineer quoted at the link,

Engineers could change Dishy’s mechanical design to achieve better heat rejection, change the dish’s electrical components to expand its thermal operating window, or develop a feature that allows Dishy’s components to operate at reduced power to create less heat. He noted the latter two options would likely be taller orders. “If changes to Dishy’s mechanical design are insufficient to reject heat at a rate exceeding its ability to produce it, software changes will be required to make the system more thermally efficient,” Keiter said. “But if speed limiting and system optimization can’t fix the issue, it will require a significant hardware revision for the commercial launch.”

“Since they’ve got a lot of custom silicon in there—likely the limiting factor—the turnaround time on this would be very slow,” he added. “They could resort to some form of active heat removal like fans or thermoelectric cooling, but then they burn a ton of power which would make Dishy even more power hungry than it already is.”

“This is a really tricky engineering problem with some insanely tight constraints,” Keiter said. “The good news is that the team is pretty sharp.”

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.

First manned mission to new Chinese space station to launch June 17th

9:19 am

The new colonial movement: China yesterday announced that the first manned mission to its new Chinese space station will launch tomorrow, June 17th, carrying three astronauts to the station’s Tianhe core module launched earlier this year.

One day before launch, China finally confirmed unofficial reports that it will launch the first crew to its new space station module, Tianhe, on June 17 Beijing Time (June 16 Eastern Daylight Time). It is China’s first human spaceflight launch in 5 years. The three men will stay aboard Tianhe for three months, the longest time in orbit for any Chinese crew.

During the three month mission the astronauts will do at least one spacewalk to likely deploy solar panels and other equipment preparing Tianhe for later modules.

The announcement also included statements by Russia that it has agreed to send Russian astronauts to the station at some point in the future.

No word on whether China will broadcast the launch live.

Rocket Lab wins contract to build two Mars smallsat planetary probes

9:13 am

Capitalism in space: Rocket Lab has won a contract to build two Mars smallsat planetary probe as part of a NASA project.

The project, led by the University of California, will have two probes dubbed Blue and Gold that will launch in 2024 on a Falcon Heavy rocket. The science goal is to place two spacecraft in Mars orbit to provide a more global look at is atmosphere. The financial goal is to show that smallsats built for less can do the same job as larger probes costing millions more.

Brazil signs Artemis Accords

9:04 am

Brazil on June 15th became the first South American country to sign the Artemis Accords, designed to bypass the limitations placed on property rights created by the Outer Space Treaty.

U.S. policy requires any nation that wishes to participate in its Artemis program to go back to the Moon to agree to the accords. Brazil is now the eleventh country to sign, joining Australia, Canada, Italy, Japan, Luxembourg, New Zealand, South Korea, the United Kingdom, the United Arab Emirates, Ukraine, and the United States.

Russia and China oppose the accords, which causes a problem for Russia as it desperately needs to partner with someone because it can’t on its own afford to build much. It is negotiating possible partnerships with China at its new space station as well as building a base on the Moon, but those agreements are not firm. And continues to send out feelers, including statements by Putin, calling for continuing cooperation with the U.S. in space.

Whether the Biden administration will make an exception for Russia in regards to the Artemis Accords remains unclear. That twelve countries have agreed to the accords however gives the U.S. greater leverage with those countries that have not yet signed.

Behind the Black supporters can now subscribe or donate using Patreon

4:58 pm

While I had been planning to add other options for my readers to support my work in addition to PayPal, today’s blacklist story, “Business that makes American flags blackballed by Paypal, Facebook, and Shopify”, finally forced me to take action.

You can now support Behind the Black by using Patreon. If you go to my website there you will have six options:

Ground support: $3 per month
Orbital support: $5 per month
Interplanetary support: $10 per month
Interstellar support: $20 per month
Intergalactic support: $50 per month

You can also make a one time custom donation of an amount of your choice.

You can still subscribe or donate using the PayPal buttons, but now you have another option. My current subscribers need do nothing, as this addition changes nothing in their PayPal account.

What this does is provide me some future security should PayPal decide to freeze my account because it wants to blackball me. As they say, the best thing a seller can have is two buyers. I now have provided my readers two internet options for supporting my work. Better for me, and better for you!

Today’s blacklisted American: Business that makes American flags blackballed by Paypal, Facebook, and Shopify

11:22 am

Banned by Paypal, Facebook, and Shopify.
The American flag: Banned by Paypal, Facebook, and Shopify.

Persecution is now cool! A Tennessee businessman who specializes in making carved wooden American flags to order, with almost any message requested, has been blacklisted by Paypal, Facebook, and Shopify, preventing him access to more than $35,000 of his own cash and causing a 90% reduction in business.

It began when, the day after the January 6th protests in DC, all three big tech companies took action to destroy Your American Flag Store,, a small business owned personally by carpenter James Staake and his family.

This past January, PayPal decided to demonetize James and his business by freezing revenue due him. In total, PayPal is holding more than $35,000 of James’ money. Now, James finds himself in an impossible situation – unable to fulfill orders because PayPal is freezing, rather than transferring, funds from James’ customers to James.

Northrop Grumman launches three military satellites using Minotaur rocket

8:56 am

Early this morning Northrop Grumman successfully used a former Minuteman rocket repurposed as a commercial rocket dubbed Minotaur to launch three military reconnaissance satellites for the National Reconnaissance Office.

The rocket’s solid-fueled stages were in themselves amazingly old.

The 69-foot-tall (21-meter) rocket is based on leftover solid-fueled motors from the U.S. Air Force’s Minuteman missile program. Designers added two Orion solid rocket motors on top of the lower two stages of a Minuteman missile to turn the bomb carriers into satellite launchers.

The Minotaur 1 rocket’s M55A1 first stage motor was cast with solid propellant in 1966 by Thiokol, now part of Northrop Grumman. The SR19 second stage motor, produced by Aerojet, was filled with its solid propellant in 1983, according to a Northrop Grumman spokesperson.

The age of the first stage means it is likely the oldest rocket motor ever used on a space launch.

The leaders in the 2021 launch race:

18 SpaceX
16 China
8 Russia
3 Northrop Grumman

The U.S. now leads China 26 to 16 in the national rankings.
