NASA adds another antenna to its Deep Space Network

9:04 am

In its on-going project to upgrade and refurbish the antenna dishes of its Deep Space Network communications, used to communicate with planetary probes beyond Earth orbit, NASA yesterday announced that the fourth of six planned new antennas is now online in Madrid.

DSS-53 is the fourth of six antennas being added to expand the DSN’s capacity and meet the needs of a growing number of spacecraft. When the project is complete, each of the network’s three ground stations around the globe will have four beam waveguide antennas. The Madrid Deep Space Communications Complex is the first to have completed its build-out as part of project. Construction on DSS-53 began in 2016.

The Deep Space Network has needed an upgrade for about a decade, and has been especially under strain as the number of missions to Mars increased during that time. After many years of delay, almost all due to budget decisions by both NASA and Congress, the upgrade began in earnest in 2016.

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

Rob Paravonian – Pachelbel Rant

6:01 pm

An evening pause: Pachelbel’s Canon in D is one of the most beautiful short pieces of music ever written, which of course is why it has been an evening pause a half dozen times before. I’ve posted a version of musicians jamming it at 3 am when they have nothing better to do, singing it a capella in a stairway, spectacularly on a guitar, as heavy metal, by a chicken (you have to watch it to understand), and played as a tango, bluegrass, gypsy, and practically any musical style you can imagine.

The rant below gives us the perspective of someone who has played the piece, and it is a perspective that might surprise you. After watching it enjoy all the other versions above, but above all make sure you watch the last one. You will then understand best what the cello player is thinking.

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.

Alignment of segments in Webb’s primary mirror completed

3:06 pm

Alignment image
Click for full image.

Astronomers and engineers have now successfully completed the alignment of the eighteen segments in the primary mirror of the James Webb Space Telescope.

On March 11, the Webb team completed the stage of alignment known as “fine phasing.” At this key stage in the commissioning of Webb’s Optical Telescope Element, every optical parameter that has been checked and tested is performing at, or above, expectations. The team also found no critical issues and no measurable contamination or blockages to Webb’s optical path. The observatory is able to successfully gather light from distant objects and deliver it to its instruments without issue.

The picture to the right shows that alignment, focused on a single star. As noted in the caption:

While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb’s optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up.

After many years delay and an ungodly budget overrun, thank goodness Webb appears to be working better than expected.

It will still be several months before actual science observations begin. Further more precise alignment adjustments need to be done for all its instruments and mirrors.

Solar scientist Eugene Parker passes away at 94

2:53 pm

R.I.P. Solar scientist Eugene Parker, whose research revolutionized solar science in the 20th century and for which the Parker Solar Probe was named, has passed away at the age 94.

As a young professor at the University of Chicago in the mid-1950s, Parker developed a mathematical theory that predicted the solar wind, the constant outflow of solar material from the Sun. Throughout his career, Parker revolutionized the field time and again, advancing ideas that addressed the fundamental questions about the workings of our Sun and stars throughout the universe.

Parker belonged to the past generations of scientists who followed the principles of the Enlightenment and believed that science was fundamentally the search for truth. He understood he could always be wrong, which brought a certain muscular strength to any ideas he proposed. He could not be lazy in any way, or his work would fail. Instead, it shone, and made what little we know of the Sun today possible.

Sadly, such men are one-by-one going from us. I wonder if the new generations will understand his mindset.

Pushback: Professor sues University of Illinois officials for suspending him for doing his job

12:56 pm

University of Illinois: run by clowns
University of Illinois: run by clowns

Jason Kilborn, a tenured law professor at the University of Illinois who had been suspended and forced to undergo sensitivity training because several unnamed students objected to an exam question that referenced racial slurs and that Kilborn had been using in his tests for a decade, has now sued a number of officials at the university.

University of Illinois Chicago law Professor Jason Kilborn’s recently filed lawsuit accuses administrators of violating his Constitutional rights, as well as defamation, false light and intentional infliction of emotional distress. It seeks damages in excess of $100,000.

Kilborn has been described by students as “top notch.” As his lawsuit against the University of Illinois Chicago moves forward, Kilborn maintains campus leaders engaged in performative retribution against him.

The lawsuit can be read here.

The named officials in the lawsuit are Michael Amiridis, the university’s chancellor, Caryn A. Bills, its associate chancellor, Julie M. Spanbauer, the law schools dean, Donald Kamm, the director of the school’s Office for Access and Equity, and Ashley Davidson, the school’s Title Ix & Equity Compliance Specialist.

I had described Kilborn’s blacklisting back in November 2021, describing in detail how Kilborn’s exam question had been in use for ten years with no objection, and was designed to help his law students uncover facts that would help lawyers defend minorities against racial abuse. I also noted that:

Recent avalanche on Mars

12:06 pm

Close-up comparison of slump
Click for full image.

Wide view comparison of slump
For full images go here and here.

Cool image time! Today the science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) released images showing a very recent avalanche, or slumping, on the interior slopes of what looks like a small three-mile-wide crater inside the easternmost reaches of the giant canyon Valles Marineris.

The comparison above, reduced and rotated to post here, is their close-up showing the change, which occurred sometime between March 2021 and February 2022. The wider comparison on the right, cropped, reduced, and annotated by me, shows a wider view to help place this slumping in the context of the crater.

Calling this an avalanche is not really accurate, as it isn’t really the fall of boulders and rocks, but the quick slumping downward of an entire section of what looks like dust or sand. As Alfred McEwen of the Lunar & Planetary Laboratory in Arizona writes in the caption:

Overview of the impact Russia’s invasion is having on the Ukraine’s space industry

9:57 am

Link here. The summary focuses on the major aerospace regions in the Ukraine, Dnipro and Kharkiv, outlining how they have so far been untargeted by the Russian invasion.

“In Dnipro, Yuzhmash and Yuzhnoye have not been bombed or targeted by missile attacks so far. One of the possible reasons is that Russia’s plan is to take them over as part of their invasion, so they intend to keep these facilities intact,” Usov said. “Because of the Russian attacks in the Dnipro region, these facilities are not operating at full capacities, and they were forced to halt work on their projects. But a share of their employees ensures their operations continue.”

The situation is the same in Kharkiv. No aerospace facilities have been directly targeted, but the war has shut down some operations, while others — especially those partnering with western nations or companies — have gone almost entirely virtual.

The article also describes a Ukrainian startup, Orbit Boy, that is trying to develop an air-launched smallsat rocket in partnership with companies in Poland and Italy. The war is making this development difficult, if not impossible.

China tests rocket engine for the next Long March 5B launches

9:44 am

China’s state-run press today revealed that a full duration test has been successfully completed of the rocket engine that will be used by the core first stage of the Long March 5B rocket that will launch the next two modules for China’s Tiangong space station.

Developed by the China Aerospace Science and Technology Corporation, the engine is designed for the core stage of the Long March-5 carrier rocket series, which will be used to launch two lab modules of China’s orbiting Tiangong space station this year.

The long-range test, lasting 520 seconds, has verified the reliability of the engine, and there will be more than 20 experimental tasks that the rocket engine will undergo to further test its performance, the company disclosed.

Though this short press release does not say, it implies that this new engine is restartable, something that on previous launches of the Long March 5B was not possible for the core stage. This lack meant that once the core stage lifted and deployed its payload into orbit, it no longer had an engine that could control it. It would within weeks crash to Earth, threatening many habitable areas around the globe. This lack also resulted in a lot of very bad press for China.

If this new engine is restartable, it means that China will be able to de-orbit it in a controlled manner, over the ocean. If so, hallelujah! It means China will finally be honoring its obligations under the Outer Space Treaty.

If not, than China will continue to prove that it is an unreliable and dangerous player on the world stage.

NASA extends Ingenuity’s mission through September ’22

9:31 am

Overview map
Click for interactive map.

NASA yesterday officially extended Ingenuity’s flight operations on Mars at least through September 2022, outlining in detail the helicopter’s hoped-for flight targets.

The map to the right shows the helicopter’s present location with the green dot, with its two possible future routes proceeding from this location indicated by dashed lines. The red dot indicates Perseverance’s present location, with its planned route from this spot indicated by the dashed lines.

Scheduled for no earlier than March 19, Ingenuity’s next flight will be a complex journey, about 1,150 feet (350 meters) in length, that includes a sharp bend in its course to avoid a large hill. After that, the team will determine whether two or three more flights will be required to complete the crossing of northwest Séítah.

Once Ingenuity crosses the rough terrain and reaches the delta, it will then be used to do more route scouting for the rover.

Upon reaching the delta, Ingenuity’s first orders will be to help determine which of two dry river channels Perseverance should take when it’s time to climb to the top of the delta. Along with routing assistance, data provided by the helicopter will help the Perseverance team assess potential science targets. Ingenuity may even be called upon to image geologic features too far afield (or outside of the rover’s traversable zone), or perhaps scout landing zones and caching sites for the Mars Sample Return program.

This ambitious plan exists because both the helicopter and its engineering team have far exceeded expectations. At the moment, there is no obvious reason why Ingenuity cannot continue to operate for years, an expectation that no one predicted.
