Ingenuity to fly on Mars no earlier than April 8th

9:03 am

NASA and the Perseverance engineering team announced yesterday their specific plans for the first flights oft he Ingenuity helicopter, setting the flight date as no earlier than April 8th.

They are presently driving Perseverance to its “airfield,” a 33×33 foot area. The deployment then will take six days, because there are a number of steps involved to position and place the helicopter on the ground properly.

Once the team is ready to attempt the first flight, Perseverance will receive and relay to Ingenuity the final flight instructions from JPL mission controllers. Several factors will determine the precise time for the flight, including modeling of local wind patterns plus measurements taken by the Mars Environmental Dynamics Analyzer (MEDA) aboard Perseverance. Ingenuity will run its rotors to 2,537 rpm and, if all final self-checks look good, lift off. After climbing at a rate of about 3 feet per second (1 meter per second), the helicopter will hover at 10 feet (3 meters) above the surface for up to 30 seconds. Then, the Mars Helicopter will descend and touch back down on the Martian surface.

Several hours after the first flight has occurred, Perseverance will downlink Ingenuity’s first set of engineering data and, possibly, images and video from the rover’s Navigation Cameras and Mastcam-Z. From the data downlinked that first evening after the flight, the Mars Helicopter team expect to be able to determine if their first attempt to fly at Mars was a success.

The data from this first attempt will determine what they do next.

UPDATE: Below the fold is an illustration of that planned first flight, showing that they hope to send the rover toward the north, take some images, and then fly it back to its airfield, with a second landing site option at the far end of its flight.

SpaceX successfully launches another 60 Starlink satellites

8:51 am

SpaceX early today successfully used its Falcon 9 rocket to place another 60 Starlink satellites into orbit, bringing that constellation to over 1,300 satellites.

The first stage landed successfully, for the sixth time. Both fairing halves were also reused, and their recovery method has now been simplified:

SpaceX has recently appeared to adjust its fairing recovery strategy. The ships previously dedicated to fairing catch attempts, GO Ms. Chief and GO Ms. Tree, have been stripped of their nets and arms, a possible sign that dry fairing recoveries will no longer be attempted. Post-splashdown recovery has proven to be fairly successful, as recent missions frequently use fairing halves that have flown once if not multiple times before.

The leaders in the 2021 launch race:

9 SpaceX
6 China
4 Russia
2 Rocket Lab

Counting all launches, the U.S. now leads China 13 to 6 in the national rankings.

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

A data-based broad look at the entire COVID epidemic, one year later

2:24 pm

The Scream by Edvard Munch
The Scream by Edvard Munch

One year ago I posted an essay entitled COVID-19: the unwarranted panic. At that time we had just begun a “15-day-lockdown” to slow the spread of the virus, a lockdown that has ended up lasting a year with literally no signs of ending, even though vaccines for the coronavirus are now available and are being administrated widely to millions.

In that essay I reviewed four early science studies that provided some solid initial data about the coronavirus, all of which strongly suggested that it was not the plague many government healthy officials at that time were proclaiming it to be. Instead, these studies showed that it was only a threat to the elderly sick, that it was relatively harmless to a young population, and that the death rate was low, likely well below 1% and possibly very comparable to the flu.

These data strongly suggested to me that lockdowns, social distancing, masks, and restrictions on the freedom of the healthy and young were all a bad idea. Better to follow the traditional response to past such epidemics in which you quarantine the sick, protect the vulnerable (the elderly), and allow everyone else to go about their lives as normal.

We did not do this, however. Instead, as a society we chose in the past year to do the exact oppose, imposing strict lockdowns, mandating social distancing and mask use everywhere, while quarantining the healthy. We did this based on the worst scenarios and models put forth by health officials, who firmly believed COVID-19 was far worse than any past epidemic, and required a new, radical, and much harsher response.

I now want to ask, one year later: Whose conclusions about the seriousness of COVID-19 were more accurate? Was it just another type of flu, though maybe somewhat worse, as I posited, or was it the deadly pestilence predicted by the world’s health authorities?

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.

Today’s blacklisted Americans: Anyone who worked for Trump

12:09 pm

The cancelled Bill of Rights
A document no one in Washington believes in.

Blacklists are back and the Democrats got ’em: It is now very clear that anyone who worked for President Trump during his term in office is now being blackballed by the political class in DC and in the media.

[R]esumes are gathering dust, book manuscripts are being rejected, and corporations are being threatened with boycotts if they hire members of Trump’s team. “They are being blocked everywhere,” said Matt Schlapp, chairman of the American Conservative Union.

It’s “natural for the party that lost the White House, just as we saw after the Bush and Obama administrations, to spend a few months in the wilderness, so to speak,” added Brian Walsh, a partner at PLUS Communications.

But this time feels different, and many critics have said it is deserved. “They took a wrecking ball to the ‘swamp.’ Why would the ‘swamp’ want them back?” a top K Street lobbyist asked. [emphasis mine]

I find the highlighted quote especially ironic, in that I think Trump’s biggest failure is that he did not take a wrecking ball to the “swamp,” never truly cleaned house, even when it was patently obvious — especially in agencies like the FBI and the Justice Department — that a housecleaning was desperately needed.

Twisted and tilted bedrock in Martian crater

11:36 am

tilted strata in Martin Crater
Click for full image.

Cool image time! The photo to the right, rotated cropped, and reduced to post here, is only a small example of the strangely tilted and twisted strata in the central peak region of 38-mile-wide Martin Crater on Mars. The full image shows more.

The picture was taken on January 12, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The section I’ve cropped out shows a series of stratified strata that are are not only significantly tipped from the horizontal, but have also been bent and deformed.

The crater itself is located about 260 miles south of Valles Marineris, as shown on the overview map below.

Yutu-2 & Chang’e-4 complete 28th lunar day on Moon

8:42 am

The new colonial movement: China’s lunar rover Yutu-2 and its lander Chang’e-4 have successfully completed their 28th lunar day on the far side of the Moon, and have been placed in hibernation for the long lunar night.

According to this article from China’s state-run press, Yutu-2 has now traveled 683 meters (2,241 feet) since its landing. In the past two lunar days the rover has traveled about 180 feet, continuing its journey to the northwest away from Chang’e-5. Their pace continues to be about 80 to 100 feet per lunar day.
