ESA asks member nations to build lander for Franklin Mars rover

9:47 am

In its most recent request for funding from the member nations of the European Space Agency (ESA), the agency has asked the member nations to finance the design and construction of a new lander for its long delayed Rosalind Franklin Mars rover, replacing the Russian lander that had became unavailable due to sanctions resulting from Russia’s invasion of the Ukraine.

According to the BBC (opens in new tab), ESA will request 360 million euros to kickstart work on the new landing system, with additional funds likely needed in subsequent years. ESA has already spent some 1.3 billion euro on the ExoMars program, which also includes an orbiter that has been studying Mars’ atmosphere and surface since 2017. ESA will put the plan in front of delegates of its 22 member states at a ministerial conference in November.

“We will have to wait if the [member states] decide to go forward with the project,” Parker said. “This concept is now proposed as part of the director general’s package within [ESA’s] exploration program for decision at the ministerial [conference].”

If ESA’s member nations agree to this plan, expect the launch of Franklyn to be delayed further. Based on the normal pace in which ESA functions, that lander will take a minimum of five years to design and build (likely much longer). Though ESA is now targeting ’28 for the launch of Franklin, which was supposed to launch this past summer after a two year delay, this plan likely means it will not get off the ground this decade.

Meanwhile, there are now at least a half dozen private companies building lunar landers that could more quickly (and for less money) get a Franklin Mars lander built for ESA. None are in Europe however, which means ESA would rather have this mission delayed years so that it can funnel money to its own contractors..

Russia’s Soyuz-2 rocket launches two military satellites

9:37 am

Russia today successfully launched from its Plesetsk spaceport two military satellites using its Soyuz-2 rocket.

Russian sources provided little information but it appears the launch was timed to allow these satellites to come close to an American military satellite.

Today’s launch of Kosmos-2561 and 2562 also seemed to mirror the trajectory of USA-326, with the American satellite passing over the cosmodrome roughly at the time of today’s launch.

If the latest launch is an inspector mission, it is possible that Kosmos-2562 is a subsatellite that was released by 2561 shortly after launch, as previous inspector satellites have done. Kosmos-2542 was believed to have been an inspector satellite, although never confirmed by Russia, and later released Kosmos-2543.

The launch was from the interior of Russia. The Soyuz-2 version launched was one with no side boosters, so that only the expendable core stage crashed in Russia.

The leaders in the 2022 launch race:

48 SpaceX
45 China
16 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 68 to 45, though it now trails the world combined 69 to 68.

The launch of 36 OneWeb satellites by the biggest version of India’s GSLV rocket is right now counting down for a launch shortly. You can watch it here.

Bedrock layers in Terby Crater on Mars

Bedrock layers in Terby Crater on Mars
Click for full image.

Cool image to end the week! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken by on July 18, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the bedrock layers on one of two very large mesas that jut out into the floor of 108-mile-wide Terby Crater.

I want to focus your eye on the spoon-shaped mesa near the top right of the photo. Note how the layers can be seen on both sides, even though the top of the mesa seems to be concave. This is strange and complex geology, made even more fascinating in that the two mesas almost reach the center of the crater floor. Why are they here? Why were they not flattened during impact, like the rest of the crater floor? Or maybe the original crater floor is the mesa top, but if so, why did the rest of the crater interior get eroded away.

The overview map below provides some context, and helps fill in some details, even if it fails to answer any of these questions.

Teachers fired and blacklisted for opposing the queer agenda in childcare and elementary schools

1:01 pm

As I did yesterday, today’s blacklisting column will cover a number of individual stories, this time focusing on the blacklisting of teachers who oppose indoctrinating very young children to the queer agenda. I am reporting more than one story in order to make sure these stories do not fall by the wayside. The harm done to the individuals does not go away, even if the news cycle considers their story stale.

Bright Horizons commitment to Critical Race Theory and the queer agenda, for toddlers
Screen capture from Bright Horizons’ own webpage.
Very clearly, Bright Horizons is determined to teach
Critical Race Theory and the queer agenda to toddlers.

First we have California teacher Nelli Parisenkova, who was fired from her job with the nationwide childcare company Bright Horizons because she for religious reasons refused to read books promoting the queer agenda to 1 to 5-year-old toddlers.

What makes this story especially egregious is the vindictive manner in which Parisenkova was treated. From the lawsuit [pdf]:

The childcare room at Bright Horizons where Ms. Parisenkova works has children’s books on the shelf that promote and celebrate same-sex relationships and marriage. When Ms. Parisenkova first started working for Bright Horizons, her supervisor at the time provided her with an informal accommodation that she would not be required to read books to the children promoting same-sex marriage. However, on or around April 7, 2022, Katy Callas, the director of the location where Ms. Parisenkova worked, discovered Ms. Parisenkova’s religious beliefs in this regard. Ms. Callas, who is lesbian, apparently took personal offense at Ms. Parisenkova’s religious beliefs.

Ukraine officials in direct negotiations with Musk about Starlink

10:22 am

According to the Ukraine’s defense minister, they are now conducting direct negotiations with Elon Musk concerning the cost of using SpaceX’s Starlink constellation as part of its war against Russia.

In an interview, Defense Minister Oleksii Reznikov said “I know that we will not have a problem” keeping the service active, citing the “personal communication” between Ukraine’s Minister of Digital Transformation Mykhailo Fedorov and Musk.

Fedorov “is responsible for the digitalization and he has a direct connection with Elon Musk. They have a personal communication, and Mykhailo was really positive” about the situation in their last discussion of the issue, Reznikov said.

I suspect that at some point, the Ukraine will start paying SpaceX some money out of the $20 million per month Musk says it costs. And it will likely draw the cash for those payments from the approximately $50 billion the U.S. has sent it in aid.

Astronomers discover an exoplanet with the density of a marshmallow

10:18 am

Using ground-based telescopes to gather more data about an exoplanet discovered by the orbiting TESS telescope, astronomers have found that it has the density of a marshmallow.

The planet orbits a red dwarf star, the most common star in the universe, and is the “fluffiest” yet seen around this type of star.

Red dwarf stars are the smallest and dimmest members of so-called main-sequence stars — stars that convert hydrogen into helium in their cores at a steady rate. Though “cool” compared to stars like our Sun, red dwarf stars can be extremely active and erupt with powerful flares capable of stripping a planet of its atmosphere, making this star system a seemingly inhospitable location to form such a gossamer planet.

Astronomers remain puzzled how such a large fluffy planet could have formed around such a dim small star.

Rate of micrometeorite impacts on Webb holding as expected

10:10 am

According to this Space.com article, the rate and size of micrometeorite impacts on the main mirror of the Webb Space Telescope has held steady at the rate and size expected, since the first surprisingly large micrometeorite impact in May that slightly dinged one mirror segment.

At this point, JWST has experienced a total of 33 micrometeoroid events, according to Smith’s slides. But the most damaging one came before JWST began science observations; in late May, a particularly large micrometeoroid struck the observatory’s mirror, leaving its mark on one golden hexagon. The team estimates that a strike of that size should occur about once a year, Smith said.

“So we got that at month five,” he said. “We haven’t seen another one yet, so it’s still consistent with the statistics that we expected.”

Smith noted that, at the current impact rate, Webb will still be meeting its five-year performance requirement 10 years into the mission. Scientists estimate that the observatory has enough fuel to operate for 20 years.

Meanwhile, one of Webb’s infrared cameras is not doing spectroscopy as engineers analyze the high levels of friction in a “grating wheel.” At this point it appears they still do not understand the cause of the friction, and thus have not come up with a plan for mitigating it.

Chandrayaan-3 now scheduled for summer 2023

10:01 am

India’s second attempt to put a rover on the surface of the Moon, Chandrayaan-3, has now been tentatively scheduled for launch in the summer of 2023.

The launch had originally been scheduled for launch in the fall of 2020, but was delayed when India shut down due to the Wuhan panic. Official at ISRO, India’s space agency, had hoped to launch by the summer of 2022, but that proved impossible. They have now delayed the mission a full year.

In fact, all earlier reports had indicated the rover was almost ready. This new delay of a full year suggests that some new issues might have been identified.

The news article at the link also notes that ISRO is now planning two unmanned orbital missions plus four launch abort tests before launching its first manned mission, dubbed Gaganyaan, not two abort tests as previously planned. They are still targeting ’24 for the manned mission.

InSight status: Barely hanging on

9:50 am

InSight's power status as of October 19, 2022

The science team for the InSight lander on Mars today posted an update on the power the spacecraft’s dust covered solar panels are producing. I have added that data to my on-going graph of these power levels, to the right. From the update:

On October 19, 2022, InSight was generating an average between 275 and 285 watt-hours of energy per Martian day, or sol. The tau, or level of dust cover in the atmosphere, was estimated at 1.5 (typical tau levels outside of dust season range from 0.6-0.7).

The jump in tau level is due to a large dust storm that developed in September more than two thousand miles away in the southern hemisphere. Though it is so far away, that storm put a lot more dust in the atmosphere above InSight, and forced engineers to shut down all but its most essential functions.

That storm is apparently continuing, and might even be growing. If so, the future of InSight is dim indeed. Any further drop in the amount of power it generates daily will likely make it unable to operate at all, and the mission will end.
