Ingenuity responds after 63 days of silence

For the past two months the science and engineering teams for the Perseverance rover and the Ingenuity helicopter in Jezero Crater have been very silent as to the status of Ingenuity. On April 25, 2023 the Ingenuity team had posted their flight plan for the helicopter’s 52nd flight, with an expected flight date the next day.

Until today, however, no information about the results of that flight had been released. Except for one update in late May describing earlier issues with communications after flight 49, the science and engineering teams maintained radio silence about that 52nd flight in April.

Today’s update finally explained that silence:

The flight took place back on April 26, but mission controllers at NASA’s Jet Propulsion Laboratory in Southern California lost contact with the helicopter as it descended toward the surface for landing.

The Ingenuity team expected the communications dropout because a hill stood between the helicopter’s landing location and the Perseverance rover’s position, blocking communication between the two. The rover acts as a radio relay between the helicopter and mission controllers at JPL. In anticipation of this loss of communications, the Ingenuity team had already developed re-contact plans for when the rover would drive back within range. Contact was re-established June 28 when Perseverance crested the hill and could see Ingenuity again.

The flight plan for the 52nd flight in April had been to fly 1,191 feet to the west. Though the Ingenuity team has not yet released the actual flight details, I have indicated with the green line on the overview map above the estimated distance and direction planned. The green dot marks Ingenuity’s position before the flight, with the blue dot marking Perseverance’s present location. The red dotted line indicates the planned route for Perseverance.

Galaxies at the dawn of time

Link here. The article takes a quick look at six galaxies found by Webb’s infrared view that all less than 650 million years after the Big Bang is thought to have occurred.

None disprove the Big Bang. All however raise serious questions about the cosmological theories that posit that event and the subsequent evolution of the universe. Take a look. It is worthwhile reading.

SpaceX launches Europe’s Euclid space telescope

SpaceX this morning successfully launched Europe’s Euclid space telescope, designed to map the spatial distribution of several billion galaxies across one third of the sky.

The first stage successfully completed its second flight, landing on a drone ship in the Atlantic. The two fairing halves completed their first flight.

This ESA science mission would have normally been launched on an Arianespace rocket, but Europe’s ability to launch anything now is nil, as it is about to retire its Ariane-5 rocket (with one launch left) and has so failed to get its replacement, Ariane-6, operational. As such, SpaceX got the business, since it is the cheapest and most reliable alternative.

The leaders in the 2023 launch race:

44 SpaceX
24 China
9 Russia
5 Rocket Lab

In the national rankings, American private enterprise now leads China in successful launches 50 to 24, and the entire world combined 50 to 41, with SpaceX by itself leads the entire world, excluding other American companies, 44 to 41.

A blacklisted American wins in court

Gerald Groff, no longer blacklisted by the post office
Gerald Groff, no longer blacklisted by the post office

Let’s end the week on a positive note. This week the big news in connection with Americans who have been blacklisted by our leftist governments has mostly focused on the Supreme Court ruling that Colorado cannot force a Christian web designer to create websites advocating the queer agenda. That 6-3 ruling affirmed the religious rights of Americans to refuse to promote ideas they find abhorrent. It also told the fascists in the homosexual movement they are not gods who can force everyone to endorse their lifestyle.

This column is not about that victory however. Instead, I want to tout another Supreme Court victory this same week, a follow-up of a story I had posted as a blacklist column back in August 2022, describing how postal worker Gerald Groff had been forced from his job because, after years of accommodating his religious beliefs and allowing him to not work on Sunday, his new post officer supervisor suddenly decided that he no longer had the right to those religious beliefs, and instituted disciplinary actions against him that forced him to quit. As I wrote then:

Another layered mesa in the Cydonia region of Mars

Another layered mesa in the Cydonia region of Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on March 22, 2023, and shows a 100-foot-high many-layered mesa in the Cydonia region of Mars.

The shadows in this picture are deceptive. The mesa’s high point is not the narrow ridge-line, but at the green dot just beyond that ridge’s northern terminus. In fact, if you were walking south from that dot and then along the crest of that ridge you would be walking downhill the entire length.

Cydonia is in the Martian northern lowland plains, in the mid-latitudes. Thus, there are many features in this picture suggesting near surface ice, such as the mounds with craters at their peak. All could be mud volcanoes as seen in many places in the northern lowland plains.

Curiosity tops a ridge to see its rough path forward

Curiosity's view ahead on June 29, 2023

After more than a month of struggle to get Curiosity to maneuver uphill through a very rocky and steep terrain, the science team today finally announced that the rover had topped the ridge and could once again see its way forward into Gediz Vallis, the slot canyon it plans to use as its route up Mount Sharp.

The panorama above, cropped, reduced, sharpened, and annotated to post here, was taken on June 29, 2023 following Curiosity’s last move forward. The yellow lines on the overview map to the right indicate the approximate area covered by this panorama. The red dotted line on both images indicates Curiosity’s planned route, with the white dotted line its actual course.

The white ridge to either side of the central peak dubbed Kukenan is actually the higher flanks of Mount Sharp. The peak of Kukenan is about a half mile away and about 400 feet higher, with those white flanks about 2.5 miles beyond. The actual peak of Mount Sharp is about 25 miles farther south and about 17,000 feet higher.

The panorama makes clear that the path forward is not going to be any less rough for Curiosity and its damaged wheels. Expect progress to be slow for many months to come.

Africa’s space agency wants to build an empire

Link here. The article is quite typical of the mainstream press, blindly in love with government-run bureaucracies. It outlines in excellent detail all the real advantages that a thriving space industry could bring to Africa, some of which are already being realized by some of the continent’s more prosperous nations. It then assumes without any justification that a large bureaucratic space agency funded by many African nations will make that possible.

In 2019, the African Union (AU) announced its space strategy. Last January the African Space Agency (AfSA) was launched, a flagship to coordinate efforts and generate synergies. It already has a physical headquarters in Cairo, but for the moment most of its rooms stand empty.

Tidiane Ouattara, an expert in space sciences at the AU, expects its 156 permanent posts to be filled next year. Outtara highlights the importance of progressing “step by step” toward the consolidation of an agency with highly qualified personnel. A solid institution capable of “defending Africa’s interests” in the international arena and of negotiating with other countries who, when exploring space, “set the rules that were best suited to them,” he says. Ouattara understands that this was the case simply because “they were first,” although he adds: “The world must understand that now Africa is also on board” and has a lot to say on controversial issues such as space debris and space traffic.

While it is certainly true that this agency, once fully staffed, could advocate for Africa’s interests on the world stage, don’t expect that from it. Instead, it is simply a place where African leaders — many of whom are very corrupt — can return favors to friends by giving them a cushy job.

For most African nations, a space program makes no sense. At best each nation should establish laws that would give its private industries as much freedom and latitude to enter this market.

As for the African Space Agency, if it really wished to promote an African space industry, it should convince a consortium of African nations to team up to finance a variety of smallsat weather, Earth resource, and surveillance satellites that nations routinely need. It should then use that money to do what the UAE has done, hire experienced universities in the west to build those satellites, under the proviso that those universities also train African engineering students and companies at the same time. These students and companies can then go back to their countries and eventually do the work themselves.

Dragon cargo freighter safely splashes down in Atlantic

After three months docked to ISS, one of SpaceX’s reusable Dragon cargo freighters safely splashed down today off the coast of Florida in the Atlantic.

This was SpaceX’s 28th cargo mission to ISS, all successful except for one launch failure not caused by the capsule itself, which post-failure analysis suggested that if it had been equipped to release parachutes it might have landed in the ocean undamaged.

This capsule brought back 3,600 pounds from the station, including some experiments that had been on the station for six years.

Webb takes infrared (heat) image of Saturn

Saturn in infrared
Click for original image.

Using the Webb Space Telescope, scientists on June 25, 2023 took the wonderful false color infrared (heat) image of Saturn above, cropped to post here, as part of a research project [pdf] to take a number of long exposures of the ringed planet in order to test Webb’s ability to see its small moons. From the press release:

Saturn itself appears extremely dark at this infrared wavelength observed by the telescope, as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright, leading to the unusual appearance of Saturn in the Webb image.

…This new image of Saturn clearly shows details within the planet’s ring system, along with several of the planet’s moons – Dione, Enceladus, and Tethys. Additional deeper exposures (not shown here) will allow the team to probe some of the planet’s fainter rings, not visible in this image, including the thin G ring and the diffuse E ring. Saturn’s rings are made up of an array of rocky and icy fragments – the particles range in size from smaller than a grain of sand to a few as large as mountains on Earth.

The picture also shows differences between Saturn’s northern and southern hemispheres, caused by the seasonal differences between the two.
