Boeing delays first manned Starliner flight again, until March of 2024

4:21 pm

Because of both parachute and wiring issues in its Starliner capsule, Boeing revealed today that it is delaying the first manned Starliner flight again, until March of 2024, so that it has time to change and test the parachutes as well as remove the flammable tape inside the capsule.

The company had been hoping to finally fly that first manned flight last month, but was forced to cancel when in June it discovered two shocking problems. First the connections between the parachutes and the capsule were too weak, and second, for some reason engineers had used tape to protect the capsule’s wiring that was too flammable and had to be replaced or covered somehow.

Boeing is taking the tape off in places where it’s easy and safe to do so and considering other remediation techniques, such as protective barriers or coatings over it, in trickier spots, Nappi said.

The parachute work is multifaceted as well. For example, Boeing has modified the soft link design to make it stronger, and the new version is being manufactured now, Nappi said. The company also decided to swap out Starliner’s parachute system, putting a new version slated for the first operational mission on board for [the crew flight test]. The new soft links will be incorporated into the new chutes, which will get to strut their stuff during a drop test soon. “We expect that the drop test will occur in mid to late November,” Nappi said. “That’s what the planning indicates at this point, and we’ll watch that closely.”

The seemingly endless number of mistakes and bad engineering that we have seen during the development of Starliner speaks very badly of Boeing in almost every way possible. These last two problems are especially egregious. Neither should have ever happened, and if so should never had been unnoticed until a mere month before launch and years into the project.

It must also be noted that March ’24 is merely a target date. Don’t bet the house on it happening then.

Russia launches new GPS-type Glonass satellite

4:02 pm

Russia today used its Soyuz-2 rocket to place a new GPS-type Glonass satellite into orbit, lifting off from its Plesetsk spaceport in the northern Russian.

Apparently this launch resulted in its lower stages falling in areas in Russia not normally used as a drop zone. No word on whether they landed near habitable areas.

The leaders in the 2023 launch race:

53 SpaceX (with a launch planned for tonight, live stream here.)
31 China
10 Russia
6 Rocket Lab
6 India

American private enterprise still leads China in successful launches 61 to 31, and the entire world combined 61 to 52, while SpaceX by itself leads the world (excluding American companies) 53 to 52.

Today’s blacklisted American: Chase bank politically cancels the accounts of several doctors, their families, and their employees

1:06 pm

JP Morgan Chase: eager to blacklist you for your opinions

They’re coming for you next: Continuing what increasingly appears to be its bank policy, JP Morgan Chase bank suddenly and without warning or reason recently canceled the bank accounts of several doctors, their families, and their employees, apparently because these doctors don’t abide by the lockdown policies and medical health advice of our government.

JPMorgan Chase is back to debanking. Once again, it’s not providing any explanations. And once again it’s targeting people who dare to question the Left Government/Woke Business conspiracy against liberty. At about the same time, it appears, Chase debanked, without warning, Drs. Syed Haider and Joseph Mercola. Wait, no. Not just them, but also Dr. Mercola’s employees – and his and their families. All without explanation.

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.

Curiosity under the shadow of a Martian mountain

Panorama showing Kukenan on August 8, 2023

Overview map
Click for interactive map

Another cool image to start the week! The panorama above was created using two navigation images taken by Curiosity on August 8, 2023. It looks almost due west at the dramatic western wall of 400-foot-high Kukenan butte.

The blue dot on the overview map to the right marks Curiosity’s present location. The yellow lines indicate approximately the area covered by the panorama above. The red dotted line indicates the rover’s planned route.

Recently JPL issued a press release touting the efforts of its engineers to overcome the very steep and rocky terrain that Curiosity is presently traversing, an effort that I have documented repeated in the past few months (see posts here and here). They had been trying to send Curiosity straight up the mountain, to no success, and finally decided to do what every hiker and trail-maker does routinely, do back and forth switchbacks to reduce the grade per step.

In June they headed slowly uphill going east. In July they turned back and worked their way uphill going west, heading back to the Jau crater complex to get a quick look at these craters, then turned again in August to head back east, slowly working uphill along the contour lines. As they do this the rover is moving closer and closer to Kukenan, the largest butte so far studied in the foothills of Mount Sharp.

This panorama is one of the best illustrations of the very complex geological history of Mars. Each layer signals a past cycle in Mars’ very cyclic history, created because of the red planet’s wide swings of rotational tilt over time. Once underground, these layers have become exposed because erosion over the eons has slowly removed the material that once buried it, leaving the butte behind.

A ghostly bullseye galaxy

A ghostly bullseye
Click for original image.

A cool image to start the week! The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope as part of a survey scientists are doing using Hubble, attempting to get high resolution images of every galaxy within about 30 million light years of the Milky Way. Prior to this census Hubble had covered about 75% of these galaxies. This particular galaxy is called a lenticular galaxy.

Lenticular galaxies like NGC 6684 (lenticular means lens-shaped) possess a large disc but lack the prominent spiral arms of galaxies like the Andromeda Galaxy. This leaves them somewhere between elliptical galaxies and spiral galaxies, and lends these galaxies a diffuse, ghostly experience. NGC 6684 also lacks the dark dust lanes that thread through other galaxies, adding to its spectral, insubstantial appearance.

The unknown is whether this is the state of a galaxy prior to becoming a spiral, or it is what it looks like as it transitions from a spiral to an elliptical. This particular galaxy is likely the latter, as it lacks the dust, but this does not have to be the rule.

Lockheed Martin opens factory to build smallsats on an assembly-line basis

10:41 am

Capitalism in space: As part of fulfilling a contract won from the Space Force, Lockheed Martin has now opened a new factory in Colorado expressly designed to build smallsats on an assembly-line basis.

Lockheed Martin’s 20,000-square-foot factory is located at the company’s Waterton campus near Denver, Colorado. It has six parallel assembly lines and capacity to manufacture 180 small satellites per year, Kevin Huttenhoff, Lockheed Martin’s senior manager for space data transport, told SpaceNews. The first satellites to be made at the facility are for the U.S. Space Force’s Space Development Agency. SDA plans to build a mesh network of hundreds of data transport and missile-detection sensor satellites in low Earth orbit.

Lockheed Martin in February 2022 won a $700 million contract to produce 42 communications satellites for SDA’s Transport Layer Tranche 1. The company in November 2020 also won a $187.5 million contract to manufacture 10 Transport Layer Tranche 0 satellites that are scheduled to launch later this month. The Transport Layer Tranche 1 satellites — projected to launch in late 2024 — will be made at the new factory. The Tranche 0 satellites were assembled at a different facility where Lockheed Martin manufactures Global Positioning System (GPS) spacecraft.

The multiple assembly lines allows the company to configure each for a different customer and satellite, with one for example producing smallsats for a military contract while another produces smallsats for a commercial customer.

Of all the big space companies, Lockheed Martin has made the most moves quickly adapting to the new space market of new rockets and small satellites. Not only has it built this facility, it has been an major investor in several new smallsat rocket companies, including Rocket Lab and ABL. It also opened its first assembly-line smallsat factory in 2017.

SpaceX conducts static fire test of Superheavy and its launchpad systems

10:32 am

SpaceX yesterday conducted a static fire test of Superheavy and its launchpad systems at Boca Chica.

After a couple of hours of chilling the fuel lines, filling of the liquid oxygen and liquid methane tanks aboard Booster 9 began at T-Minus 67 minutes. The liquid oxygen tank was fully filled with the liquid methane only partially filled with what was required for the test.

After a smooth countdown, Booster 9 lit all 33 Raptor engines, however, 4 shut down early during the 2.74-second duration test. The test was intended to last 5 seconds.

The new water deluge system seemed to work as intended, albeit with a very short firing of the engines. Instead of a giant dust cloud that is usually formed after a static fire test, this test created a steam cloud that dissipated fairly quickly following the test.

The premature shutdown and the even earlier shut down of four engines suggests SpaceX still has kinks it needs to work out. No surprise. It will now probably switch out those four engines, analyze the test, and do it again. It will do so partly because it needs to before the orbital test flight, and partly because it can’t do that test flight because the FAA has still not issued a launch license.

I have embedded the video of that test below the fold.

The Moon as seen by Chandrayaan-3

India’s space agency ISRO yesterday released the first images taken of the Moon by Chandrayaan-3, soon after entering lunar orbit.

The picture to the right is a screen capture from the short movie the agency compiled from those images, available at the link. The pictures were taken on August 5th, during the engine burn that put the spacecraft into lunar orbit. A solar panel can be seen on the left, with the cratered lunar surface to the right.

Chandrayaan-3 is presently undergoing a series of engine burns to lower its orbit in preparation for a planned August 23rd lunar landing in the high southern latitudes of the Moon.

Chandrayaan-3 enters lunar orbit

9:38 am


Click for interactive map.

India’s Chandrayaan-3 spacecraft today successfully entered lunar orbit, where it will spend the next week or so slowly lowering its orbit in preparation for a landing attempt by its Vikram lander on August 23rd.

Chandrayaan-3 began a roughly 30-minute burn around 9:30 a.m. Eastern, seeing the spacecraft enter an elliptical lunar orbit, the Indian Space Research Organization (ISRO) stated via social media. “MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity,” ISRO Tweeted. “A retro-burning at the Perilune was commanded from the Mission Operations Complex (MOX), ISTRAC, Bengaluru.”

The spacecraft will gradually alter its orbit with a burn to reduce apolune Sunday, Aug. 6. It will settle into a 100-kilometer-altitude, circular polar orbit on Aug. 17. From here, the Vikram lander will separate from the mission’s propulsion module and enter a 35 x 100-km orbit in preparation for landing.

If the landing attempt is successful, the Pragyam rover will roll off Vikram to operate for about two weeks on the lunar surface in the high southern latitudes of the Moon.

Meanwhile, the Russian lander Luna-25 will launch on August 10th. Since the rocket that launches it and engines it carries are larger than that used by Chandrayaan-3, it will likely land in Boguslawsky crater, before Vikram touches down nearby.

Astra lays off 25% of workforce, mostly in its rocket departments

10:07 am

Astra revealed yesterday that it has laid off 25% of its workforce, with most of those jobs coming from those working of developing its rocket, in order to focus the company on its rocket engine business, the only area it at present has a chance of earning revenue.

The reallocation and layoffs are expected to delay testing of the under-development Rocket 4 and Launch System 2.0, Astra said. The affected employees worked in the company’s launch, sales and administration and “shared services” departments. Workforce reductions are expected to save the company more than $4 million per quarter beginning in the fourth quarter of this year.

Astra, which is facing dwindling cash reserves, is no doubt looking for a way to further reduce operating expenses while also bolstering its spacecraft engine business, the only business unit that currently has a near-term chance of generating revenue. The spacecraft engine technology is sourced from Astra’s acquisition of propulsion developer Apollo Fusion, which closed the day Astra went public in July 2021.

Indeed, Astra said that it had closed 278 committed orders of the Astra Spacecraft Engine product through the end of March, which totals around $77 million in contracts once the engines are delivered. A “substantial majority” of these orders will be delivered through the end of 2024, the company said.

What these actions mean is that Astra is no longer a rocket company. It might return eventually, but for now there is little chance it will resume launches for years.

It is interesting that this action was revealed only one day after a class-action lawsuit was dismissed by investors against the company for claiming that it would soon be launching 300 times per year.

Engineers regain full control over Voyager 2

3:29 pm

A longshot effort by engineers has succeeded in re-establishing full communications with Voyager 2, launched in 1977 and flying outward at the edge of the solar system.

“The Deep Space Network used the highest-power transmitter to send the command (the 100-kw S-band uplink from the Canberra site) and timed it to be sent during the best conditions during the antenna tracking pass in order to maximize possible receipt of the command by the spacecraft,” Voyager project manager Suzanne Dodd told AFP. This so-called “interstellar shout” required 18.5 hours traveling at light speed to reach Voyager, and it took 37 hours for mission controllers to learn whether the command worked, JPL said in a statement.

The probe began returning science and telemetry data at 12:29 am Eastern Time on August 4, “indicating it is operating normally and that it remains on its expected trajectory,” added JPL.

Based on a weak signal received earlier, engineers were confident that the spacecraft was functioning in good order despite the loss in communications, and would automatically re-orient itself properly when it did an automatic reset in October. This attempt however fixed things now.

Regardless, the spacecraft probably only has a few more more years of operations before its nuclear powered source finally runs out sometime after 2025.

Today’s blacklisted American: Pediatrician fired for raising questions about COVID jab at public meeting

2:26 pm

Renata Moon, testifying on December 7, 2022
Renata Moon, testifying on December 7, 2022.
Click to hear her testimony.

They’re coming for you next: After pediatrician Renata Moon testified at a December 7, 2022 public Capitol Hill event organized by Senator Ron Johnson (R-Wisconsin), where she raised serious and very legitimate questions about the COVID jab and the risks it might carry, she was fired as a teacher by Washington State University for daring to express such thoughts out loud.

So, what horrible things did she say at that December 2022 event?

Dr. Moon testified that she had only seen two or three cases of myocarditis, a form of heart inflammation, while practicing for more than 20 years. But after the COVID-19 vaccines were rolled out, she said, she has been seeing more cases, and heard about others from fellow doctors. “There’s clearly been a massive increase,” Dr. Moon said.

Dr. Moon also pulled out the package insert for the vaccines, or a piece of paper that typically outlines warnings, ingredients, and other information for a vaccine. The insert for the COVID-19 vaccines has no information and says, “intentionally blank,” the U.S. Food and Drug Administration has acknowledged. “How am I to give informed consent to parents when this is what I have?” Dr. Moon said.

All she did was note the obvious increase in myocarditis after the rollout of the jab, something that has now been documented repeatedly by studies (see just a few examples here, here, here, and here), while adding that though by law she as a doctor is required to provide patients with all information about the risks of a treatment, the government had intentionally denied her that information.

For this, Washington State University officials immediately reported her to the Washington Medical Commission (WMC), which at that time (and maybe even now) considers any statement expressing any skepticism about the efficacy of the COVID jab by any doctor to be “misinformation” that justifies the revocation of his or her medical license. In the university’s letter [pdf] informing her of its actions as well as warning her that it was considering firing her, it clearly indicated that it considered her testimony as her fundamental crime.

A hiking paradise on Mars!

A hiking paradise on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, sharpened, and annotated to post here, was taken on May 21, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows one of Mars’ more impressive mountains with the Sun somewhat low in the western sky, resulting in the long dark shadows on the eastern slopes.

The line is my quick attempt to mark the obvious route that would be taken along that ridge line to get from the bottom to the top. This could be a hiking trail, or a road. In either case, the elevation gain from the bottom of the ridge to the plateau on top would be about 3,900 feet in about a mile and a half, very steep for Earth — at approximately a 26 degree grade — but probably quite doable in the one-third Martian gravity.

The lower end of my proposed route however is hardly the bottom of the mountain. The slope, now alluvial fill made up of dust and debris from above, continues downhill for another 5,400 feet. All told, from top to bottom the elevation gain is about 9,300 feet over 8.5 miles.

Proposed exclusion zone restrictions revealed for new Sutherland spaceport in Scotland

10:35 am

A map of the proposed 50-square-kilometer exclusion zone that will be required for launches at the new Sutherland spaceport in Scotland has now been obtained by the Northern Times, which appears to be a local newspaper.

The zone would cover much of Melness Crofters’ Estate, and ironically it would also include a significant part of the neighbouring Eriboll Estate, owned by Danish entrepreneur Anders Holch Polvsen, who launched a failed legal challenge against the spaceport. Highland Council is in the process of finalising the details of the proposed restrictions which will then be put out for a 12-week public consultation and go before Highland councillors for final approval.

Ramblers Scotland, which promotes access to the outdoors, has said it will “carefully study” the final proposals.

Only during the launches does it appear the zone would be this large. Between launches the zone would be limited to a radius of 1.8 kilometers around the launchpads.

With twelve launches planned per year, this zone could seriously impact local activities, though how much is not clear. Not many people live in the area, and the land inside the zone is mostly used as grazing land or for recreational activities, many apparently organized by Ramblers Scotland. We should therefore expect some opposition to this plan when this zone is discussed during that 12-week public consultation time period.

Scientists release infrared image of the Ring nebula, taken by Webb

The Ring Nebula, in false color by Webb
Click for original image.

Scientists yesterday released the first false-color infrared image of the Ring nebula taken by the Webb Telescope. That image, cropped to post here, is to the right. From the press release, which is heavy with platitudes but little information:

Approximately 2,600 lightyears away from Earth, the nebula was born from a dying star that expelled its outer layers into space. What makes these nebulae truly breath-taking is their variety of shapes and patterns, that often include delicate, glowing rings, expanding bubbles or intricate, wispy clouds. These patterns are the consequence of the complex interplay of different physical processes that are not well understood yet. Light from the hot central star now illuminates these layers.

Just like fireworks, different chemical elements in the nebula emit light of specific colours. This then results in exquisite and colourful objects, and furthermore allows astronomers to study the chemical evolution of these objects in detail.

It appears this image was produced using Webb’s near infrared instrument. Further data from its mid-infrared instrument has not yet been released. For a Hubble image of the Ring Nebula, in optical light that the human eye sees, go here.

NASA agrees to let Axiom fly a fourth private manned mission to ISS

10:10 am

NASA and Axiom have now signed a new agreement allowing Axiom to fly a fourth private manned mission to ISS, tentatively scheduled for no earlier than August 2024.

Through the mission-specific order, Axiom Space is obtaining from NASA crew supplies, cargo delivery to space, storage, and in-orbit resources for daily use. The order also accommodates up to seven contingency days aboard the space station. This mission is subject to NASA’s pricing policy for the services that are above space station baseline capabilities.

The order also identifies capabilities NASA may obtain from Axiom Space, including the return of scientific samples that must be kept cold and other cargo, and the capability to use the private astronaut mission commander’s time to complete NASA science or perform tasks for the agency.

The company has already hired SpaceX to provide the transportation to and from ISS, using its Falcon 9 rocket and one of its fleet of four manned Dragon capsules.

Despite good first images from Euclid, the orbiting telescope has a problem

10:05 am

Even though the first light images from Euclid have been sharp and exactly what astronomers want, the orbiting telescope designed to make a 3D map of billions of galaxies has an issue that will likely put some limits to that map.

When the telescope started booting up, ESA observers were concerned by the appearance of light markings on the first images relayed to Earth. This, it confirmed, was due to sunlight filtering into the telescope, “probably through a tiny gap”.

A correction to Euclid’s position was able to offset this issue. It means that while the ESA is confident Euclid will be fine to proceed with its mapping mission, particular orientations for the telescope may not be possible.

A limitation like this means that the telescope will not being able to look in some directions and get mapping images. Thus, the overall map will have gaps, though it appears at this moment that the scientists think those gaps will not seriously impact the telescope’s overall work. We shall see.

Update on the technical progress at Boca Chica, preparing for the next Starship/Superheavy orbital test

9:59 am

Link here. Lots of progress had been made in getting the pad and the rocket ready for that next orbital test flight, with the first static fires tests of Superheavy using the launchpad’s new water deluge system are now expected in the coming week.

The company is also preparing additional prototypes of Superheavy and Starship for later orbital tests. even as it upgrades the assembly facilities, replacing temporary tents with actual buildings. More details, including videos, at the link.

Meanwhile, the only word from the FAA about SpaceX’s application for a launch permit has been a warning that it will not issue that permit until it is good and ready, suggesting the company should not expect to launch in August, as I have been predicting for months.

    • The changes will increase its payload capacity, allow it to dock directly to a port rather than being berthed by a robot arm, and — most importantly — refine is ability to raise ISS’s orbit using its engines. This last capability replaces the Russians, and will be a need that future commercial stations will require.

Pushback: Student wins against school officials who tried to suppress her first amendment rights

Maggie DeJong
Maggie DeJong, fighting back hard and winning

Bring a gun to a knife fight: In April Maggie DeJong, a student at Southern Illinois University Edwardsville (SIUE), sued [pdf] three of the college’s faculty members for attempting in 2022 to both punish her and well as silence her from her first amendment right to speak, simply because some other leftist students complained they did not like her opinions. As I wrote in April when I first reported this story:

These officials issued three “no contact” orders against DeJong, forbidding her to have any contact with three co-students in her program, simply because she had religious and political opinions they disagreed with and did not wish to hear. This orders essentially blacklisted her from the program, because of its small nature, and were literally a priori gag orders on her right to freely express her opinions. The officials also admitted that DeJong had violated no school policy, nor did they provide her any due process before issuing the orders. When challenged by DeJong’s lawyers, the university quickly realized the utter illegality of these orders, and cancelled them.

Unlike most recent cases of blacklisting, DeJong did not sue the university but the individuals involved, making them personally liable. » Read more

The dry and mountainous terrain west of Jezero Crater

The dry and mountainous terrain west of Jezero Crater
Click for original image.

Since my earlier update today about Perseverance and Ingenuity mentioned the very diverse and strange geology known to exist west of Jezero Crater and where the rover is eventually headed, I thought it worthwhile to post another cool image of that terrain.

The picture to the right, rotated, cropped, reduced and sharpened to post here, was taken on May 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled a “terrain sample” image, the location was likely chosen by the camera team in order to fill a gap in the camera’s schedule so that they can maintain its proper temperature. Having a gap that put the spacecraft over this region to the west of Jezero was however a great opportunity to get another look at this rocky, mountainous, and very parched terrain, located in Mars’ very dry equatorial regions.

A grateful thank you to all who contributed during July’s fund-raising campaign

11:00 am

My annual July fund-raising campaign for Behind the Black, celebrating the thirteenth anniversary of my first posts back in 2010, has now ended.

This was the second most successful monthly fund-raising campaign ever. Thank you again to everyone who has who donated or subscribed. I would like to email thanks to you all, but there are too many. Please accept this general thank you instead. It is difficult to explain what your support means to me, as it has raised the earnings so far this year to almost match last year’s numbers.

This thank you notice will remain at the top of the page for the next few days. Scroll down for new stories.

From the original post:
——————————
I sincerely dislike begging for donations and subscriptions, which is why I shortened my February campaign from its normal four weeks to only two. I wanted to spare both my readers and myself some of this pleading.

Sadly, that decision resulted in a total drop in donations, so that at this point in 2023 the website’s income is down 25% from last year, even though my traffic continues to be robust, in the range of four to five million hits per month. I am therefore forced to run this July campaign for the full four weeks, unless the donations and new subscriptions in the next few weeks make up this difference.

Please consider supporting my work, by using one of four methods (Zelle, Patreon, Paypal, or check) described in the tip jar elsewhere on this page. I take no advertisements nor accept any sponsors in order to keep the website clean, easy to read, and to avoid any accusations of conflict of interest. Your support leaves me entirely independent, able to say whatever I think while being free from censorship or reprisals.

Cool image time! With Perseverance and Ingenuity in the past week getting close together for the first time in months, the Perseverance team naturally turned its high resolution mast cameras at the helicopter. The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 2, 2023 by the rover’s left mast camera, showing Ingenuity only about two hundred feet away.

The blue dot on the overview map above shows Perseverance’s present location, with the green dot marking Ingenuity’s. The picture to the right is therefore looking almost due south. The red dotted line indicates the rover’s planned route, moving towards Neretva Vallis, the gap in the rim of Jezero Crater from which the delta had flowed, eons ago. The rover’s goal is to eventually enter that gap and explore the very diverse and strange geology known to exist outside the crater to the west.

We should also expect even better images of Ingenuity in the next week. Its 54th flight is scheduled for today, in which the engineering team wants to send the helicopter on a simple straight up and down hop of sixteen feet in order to better “localize” the helicopter. With Perseverance less than two hundred feet away, its cameras should be able to assemble a great movie of that flight.

New software detects its first potentially dangerous asteroid

9:32 am

New software designed to detect asteroids, developed for use with the Rubin Observatory presently being built in Chile, has successfully discovered its first potentially hazardous asteroid (PHA) using data from another smaller operational ground-based telescope.

The discovered asteroid is 600 feet long, large enough to pose a real threat should it ever hit the Earth. Fortunately, the data says that though its orbit can take it as close as 140,000 miles there is no impact likely in the foreseeable future.

When the Rubin telescope begins its planned ten year survey of the entire night sky in 2025, this software is expected to almost triple the number of known potentially-hazardous-asteroids, from 2,350 to almost 6,000.

Funded primarily by the U.S. National Science Foundation and the U.S. Department of Energy, Rubin’s observations will dramatically increase the discovery rate of PHAs. Rubin will scan the sky unprecedentedly quickly with its 8.4-meter mirror and massive 3,200-megapixel camera, visiting spots on the sky twice per night rather than the four times needed by present telescopes. But with this novel observing “cadence,” researchers need a new type of discovery algorithm to reliably spot space rocks.

Thus, the development of this new software.
