Europe removes its science instruments from future Russian lunar missions

8:43 am

The Europe Space Agency (ESA) yesterday announced that because of Russia’s invasion of the Ukraine it will no longer fly any science instruments on three upcoming Russian unmanned lunar probes.

ESA will discontinue cooperative activities with Russia on Luna-25, -26 and -27. As with ExoMars, the Russian aggression against Ukraine and the resulting sanctions put in place represent a fundamental change of circumstances and make it impossible for ESA to implement the planned lunar cooperation. However, ESA’s science and technology for these missions remains of vital importance. A second flight opportunity has already been secured on board a NASA-led Commercial Lunar Payload Services (CLPS) mission for the PROSPECT lunar drill and volatile analysis package (originally planned for Luna-27). An alternative flight opportunity to test the ESA navigation camera known as PILOT-D (originally planned for Luna-25) is already being procured from a commercial service provider.

In other words, Europe is switching to the many private American companies that are developing lunar landers for NASA science instruments. It has also signed onto a Japanese lunar mission. All have payload space, and all are willing to take the cash of a new customer.

Meanwhile, this is how Dmitry Rogozin responded to this decision:

“Good riddance! One less European dame off our backs, so Russia should go far with a lighter load,”

To sum this all up, when it comes to space, the Ukraine invasion has been Russia’s loss, and everyone else’s gain. Even if the invasion were to end today, it will take at least a decade to re-establish Russia’s business ties with the west.

Unfortunately, the invasion will cost the Ukraine as well. In making the above announcement ESA officials also said that it is looking for alternatives to the Ukrainian rocket engines used in its Vega-C upper stage.

At the news conference, ESA also discussed the future of its small Vega rocket, which relies on Ukraine-built engines in its upper stage. The engines are manufactured by the Ukrainian company Yuzhmash, which is based in the tech city of Dnipro. Although Dnipro has been under heavy bombardment, there have been no official reports so far about damage to Yuzhmash. It is, however, clear that ESA doesn’t expect to continue its partnership with the company in the future. “We now have sufficient engines for 2022 and 2023,” Aschbacher said. “We are working on options for 2024 and onwards based on different technologies.”

Daniel Neuenschwander, ESA’s director of space transportation, added: “We are working on engine opportunities within Europe and outside of Europe, which are either tested or, even better, already existing and fully qualified.”

Whether ESA completely breaks off its partnership with the Ukraine however is not certain. Should the war continue to favor the Ukraine, then it could be that partnership will continue. Only time will tell. Right now, it is simply prudent for ESA to look for more stable alternatives.

Frozen lava in Mars’ volcano country

5:31 pm

The frozen lava of the Athabasca flood plain
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on January 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what appears to be at first glance a relatively featureless plain with a lighter material covered by a patchwork of darker material.

Note however the lack of craters. Except for several faint depressions near the image’s center, there are none. And those depressions look like the expression of craters that have been covered by material. Is the two-toned surface here an expression of past lava flows? Or are we seeing an ice-sheeted plain, with the patches representing higher terrain above that plain?

The overview map below answers the question somewhat clearly.

Today’s blacklisted American: Seattle’s public schools to hold “listening tours” that exclude whites

3:22 pm

Jim Crow celebrated in Seattle!
Seattle, home of the new Jim Crow!

“Segregation today, segregation tomorrow, segregation forever!” The public school system of the city of Seattle (SPS) has now scheduled a number of “listening sessions” for parents that, while designed to discuss ways to make the schools more welcoming, specifically exclude whites from the sessions, and divide the sessions by race and ethnicity.

SPS and the Seattle Council of Parent Teacher Student Association (PTSA) is hosting seven listening sessions with superintendent Dr. Brent Jones. The remote tour starts on April 19. One of the sessions is for Black families and a second for Native American families. They also recently added meetings specifically for East African and Black Immigrant Families, plus Multigenerational African American Black Families. The district and PTSA believe these race-exclusionary meetings promote equity. But they may represent illegal discrimination.

While there are sessions open to the general public, most of the sessions are segregated and discriminatory. And God forbid Seattle run a listening session just for whites! Why, that would be racism!

In a sense, this story out of Seattle is not news. I have repeatedly reported stories of Seattle government and corporate officials discriminating illegally against whites while unfairly providing their favorite minorities special privileges. Some examples:

Webb’s coldest instrument reaches operating temperature

1:32 pm

The engineering team announced today that the mid-infrared instrument on the James Webb Space Telescope has now cooled to its operating temperature of -447 degrees Fahrenheit, less than 7 kelvin degrees above absolute zero.

On April 7, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by NASA and ESA (European Space Agency) – reached its final operating temperature below 7 kelvins (minus 447 degrees Fahrenheit, or minus 266 degrees Celsius).

Along with Webb’s three other instruments, MIRI initially cooled off in the shade of Webb’s tennis-court-size sunshield, dropping to about 90 kelvins (minus 298 F, or minus 183 C). But dropping to less than 7 kelvins required an electrically powered cryocooler. Last week, the team passed a particularly challenging milestone called the “pinch point,” when the instrument goes from 15 kelvins (minus 433 F, or minus 258 C) to 6.4 kelvins (minus 448 F, or minus 267 C).

Before science operations can begin the instruments still need further calibration and testing. Expect the first infrared images sometime in the next month or so.

Space Perspectives unveils luxurious interior of Neptune high altitude balloon

9:41 am

Capitalism in space: Space Perspectives has now unveiled the high class stateroom interior that it plans to put inside its Neptune high altitude balloon that will take tourists to 30+ miles altitude.

Space Perspective just released artist’s illustrations of the interior of Spaceship Neptune, which will include 360-degree panoramic windows and even a restroom with a view. The announcement Tuesday (April 12) coincided with the anniversary of the first human spaceflight by cosmonaut Yuri Gagarin in 1961.

Based on the imagery, Spaceship Neptune’s cabin appears to come in at least a couple of configurations. One has reclining seats, for example, while another with couches can accommodate a “more intimate dinner for two or special event,” Space Perspective representatives said in a statement on Tuesday.

Space Perspective will provide food and beverage services, and the capsule features mood lighting that can be dimmed to see stars or the curvature of Earth outside. Also included in the capsule’s “Space Lounge” will be a telescope, interactive screens and decorations such as floor lamps and plants to “remind us of the interconnected nature of our planet,” the company added.

The company hopes to begin commercial flights by ’24, each of which will last about six hours. Tickets are priced at $125K each, with the company saying it already has 600 people on its waiting list.

Astronomers confirm comet with largest nucleus ever found

9:29 am

Using the Hubble Space Telescope astronomers determined that the nucleus of Comet Bernardinelli-Bernstein (C/2014 UN271) is about 80 miles wide, making it the largest comet on record.

The estimated diameter is approximately 80 miles across, making it larger than the state of Rhode Island. The nucleus is about 50 times larger than found at the heart of most known comets. Its mass is estimated to be a staggering 500 trillion tons, a hundred thousand times greater than the mass of a typical comet found much closer to the Sun.

The behemoth comet, C/2014 UN271 (Bernardinelli-Bernstein) is barreling this way at 22,000 miles per hour from the edge of the solar system. But not to worry. It will never get closer than 1 billion miles away from the Sun, which is slightly farther than the distance of the planet Saturn. And that won’t be until the year 2031.

The previous record holder is comet C/2002 VQ94, with a nucleus estimated to be 60 miles across. It was discovered in 2002 by the Lincoln Near-Earth Asteroid Research (LINEAR) project.

This measurement does have a great deal of uncertainty, as Hubble cannot yet resolve the nucleus, and thus its diameter was determined by computer models based on the size of the comet’s coma, or surrounding atmosphere.

The comet itself has an orbit 3 million years long, which means it has zipped into the inner solar system many many times. The reason its nucleus remains so large is because its orbit never gets that close to the Sun, so its material does not get burned off so much with each perihelion. That it exists suggests there could be many such large comets which never dip close to the Sun.

MAVEN and Al-Amal scientists sign agreement to collaborate

1:20 pm

Scientists running the Mars orbiters MAVEN (from NASA) and Al-Amal (from the United Arab Emirates [UAE]) have signed an agreement to share data and — more importantly — coordinate their observations of the Martian atmosphere.

A new partnership that encourages the sharing of data between NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) project and the Emirates Mars Mission’s (EMM) Hope Probe (Al-Amal in Arabic) will enhance scientific returns from both spacecraft, which are currently orbiting Mars and collecting data on the Red Planet’s atmosphere. The arrangement is expected to add value to both MAVEN and EMM, as well as the scientific communities involved in analyzing the data the missions collect.

MAVEN went into orbit around Mars in 2014. Its mission is to investigate the upper atmosphere and ionosphere of Mars, offering an insight into how the planet’s climate has changed over time. “MAVEN and EMM are each exploring different aspects of the Martian atmosphere and upper-atmosphere system,” said Shannon Curry, MAVEN principal investigator from the University of California, Berkeley. “Combined, we will have a much better understanding of the coupling between the two, and the influence of the lower atmosphere on the escape to space of gas from the upper atmosphere.”

The EMM Hope Probe, which went into Mars orbit in 2021, is studying the relationship between the upper layer and lower regions of the Martian atmosphere, giving insight into the planet’s atmosphere at different times of the day and seasons.

What this agreement means is that the two science teams can more quickly match up the data from both orbiters, and figure out the relationships between both.

Pushback: Black waitress sues NYC mayor over COVID shot mandate

Don’t comply! A waitress who formerly worked at Yankee Stadium but lost her job because of the COVID shot mandate imposed by New York City mayor Eric Adams is now suing him and the city. Her suit is also fueled because of Adams’ arbitrary decision to cancel the mandate for wealthy athletes.

Virginia Alleyne’s Manhattan Supreme Court lawsuit claims Hizzoner’s exemption for athletes and performers is “arbitrary and capricious” and an “abuse of discretion.”

“For him to allow millionaires to work and to punish the workers who are the lifeblood of this city is just horrendous,” Alleyne told The Post. “So many workers have lost their jobs, yet he’s rewarding the millionaires because he doesn’t want them coming after him,” she continued. “We are being punished by a blatant and egregious double standard.”

The 57-year-old Upper East Side single mom said she was placed on unpaid leave from her job as a waitress at the stadium’s high-end restaurant Legends Suite Club in September because she is unvaccinated.

This quote from her lawyer illustrates quite starkly how incredibly arbitrary and capricious Adams’ edict is:

ULA orders 116 rocket engines from Aerojet Rocketdyne for its Vulcan upper stage

10:33 am

Capitalism in space: In order to meet its contract with Amazon to launch a lot of Kuiper satellites, ULA has now ordered 116 rocket engines from Aerojet Rocketdyne for the Centaur upper stage of its new and as-yet unlaunched Vulcan-Centaur rocket.

Aerojet said this was the company’s largest ever contract for the RL10 engine. The large purchase of rocket engines comes on the heels of Amazon’s announcement April 5 that it selected Arianespace, Blue Origin and ULA to launch up to 3,236 satellites for its Project Kuiper broadband constellation.

CEO Tory Bruno said ULA plans to fly Vulcan’s first mission late in 2022. Winning the Amazon deal would more than double the annual rate of Vulcan launches to as many as 25 per year, and ULA will ramp up production to meet the demand, Bruno said last week at the Space Symposium.

ULA’s engine choice for Vulcan’s upper stage dates back to 2018 when it selected a variant of the RL10, the same engine used to power the upper stages of ULA’s legacy rockets Atlas 5 and Delta 4 Heavy. Over the past 60 years, more than 450 RL10 engines have flown on various ULA heritage vehicles.

Meanwhile, ULA hopes to get its first BE-4 engines from Blue Origin, needed for the Vulcan first stage, this summer. Vulcan-Centaur cannot make its first launch until it gets some flightworthy BE-4 engines, and these are now three years behind schedule.

Interstellar meteor impacted Earth in 2014

10:28 am

According to classified military data just released, it appears that an asteroid from interstellar space impacted the Earth in 2014, with some of its pieces possibly hitting the ocean in the south Pacific.

The meteor ignited in a fireball in the skies near Papua New Guinea, the memo states, and scientists believe it possibly sprinkled interstellar debris into the South Pacific Ocean. The confirmation backs up the breakthrough discovery of the first interstellar meteor—and, retroactively, the first known interstellar object of any kind to reach our solar system—which was initially flagged by a pair of Harvard University researchers in a study posted on the preprint server arXiv in 2019.

Amir Siraj, a student pursuing astrophysics at Harvard who led the research, said the study has been awaiting peer review and publication for years, but has been hamstrung by the odd circumstances that arose from the sheer novelty of the find and roadblocks put up by the involvement of information classified by the U.S. government.

The speed and angle in which the object hit the atmosphere are why the scientists believe it comes from outside the solar system.

Siraj is actually hoping to mount a mission to recover parts of this asteroid, something that is extremely unlikely. First, the meteor itself was small, so it likely all burned up in re-entry. Second, even if pieces survived, finding them on the bottom of the Pacific is likely impossible.
