2,000 nearby stars found that see the Earth cross in front of the Sun

Astronomers have identified 2,134 nearby stars that at some point in the past, present, or future are properly positioned along the solar system’s ecliptic so that the Earth can be seen transiting in front of the Sun.

From their paper’s abstract:

[W]e report that 1,715 stars within 100 parsecs from the Sun are in the right position to have spotted life on a transiting Earth since early human civilization (about 5,000 years ago), with an additional 319 stars entering this special vantage point in the next 5,000 years. Among these stars are seven known exoplanet hosts, including Ross-128, which saw Earth transit the Sun in the past, and Teegarden’s Star and Trappist-1, which will start to see it in 29 and 1,642 years, respectively. We found that human-made radio waves have already swept over 75 of the closest stars on our list. [emphasis mine]

I like the detail highlighted. Of the stars that could definitely identify the Earth by transits, 75 are also now close enough to have also heard our radio broadcasts. Should any of those stars also have a sufficiently advanced alien civilization, they could know of our existence. These same stars in turn make for very good targets of study for us to see if there is alien life there.

ULA to temporarily stop using new engine nozzle because of vibration issue

Capitalism in space: Because of an unexpected vibration issue seen during its first launches, ULA engineers have decided to temporarily stop using a new engine nozzle developed for the upper stage of both its Atlas 5 and new Vulcan rocket.

ULA’s CEO Tory Bruno said June 23 that the company is studying the data from the flight and has not yet decided what corrective action, if any, it might take. In the meantime, the new version of the RL10 [engine] with the carbon nozzle extension will not be used in upcoming Atlas 5 missions, Bruno said during a talk at the Secure World Foundation’s Summit for Space Sustainability.

Concerns about vibrations in the engine led ULA to delay the launch of the Space Force STP-3 mission that had been scheduled for June 23 and was planned to fly with the enhanced RL10. The company has not announced a new launch date for STP-3. ULA first plans to launch Boeing’s Starliner Orbital Flight Test 2 mission to the International Space Station scheduled for July 30. “It’ll be several missions, probably next year” before ULA decides whether to fly the RL10 configuration with the nozzle extension, said Bruno. The company wants to be “fully satisfied that we understand it.”

Below the fold is the live stream from that May launch, cued to show that vibration. It is their intention to go back to the older nozzle configuration for the next few launches.

Study proposes new radiation standards in space

Health limits of radiation for space missions

A new report issued today from the National Academies of Science is recommending that NASA adopt a new health standard for limiting the exposure of astronauts to radiation during long space missions. The new standard, based on a maximum accumulative dosage of 600, is indicated by the figure to the right, taken from the report [pdf] and annotated to show both the new recommendation as well as the standards used by other space-faring nations.

The key result of this change is expressed in the report in this one sentence:

Today’s blacklisted American: Jeff Bezos, founder of Amazon and Blue Origin

Jeff Bezos, sentenced to death!
Jeff Bezos: The next target in America’s daily two-minute hate.

They’re coming for you next: As a clear indication of the ugliness of modern society and the eager willingness of far too many Americans to hurt or even kill those they disagree with or do not like, two different petitions have now garnered more than 175,000 signatures demanding that Jeff Bezos, the founder of Amazon and Blue Origin, be forced to die in space rather than safely return home during his planned July 20th suborbital commercial flight on his New Shepard spacecraft.

The two petitions can be seen here and here. Both have received a lot of media attention, such as these articles in the Guardiane, MSN, and the New York Post, all of which immediately caused the numbers of people signing the petitions to skyrocket. Both petitions are now “one of the top signed on Change.org!”

Ingenuity completes 8th flight, moving south with Perseverance

Perservance's location, June 17, 2021
Click for interactive map.

On June 21, 2021 the Mars helicopter Ingenuity successfully completed its eighth flight, leapfrogging south past the rover Perseverance.

During the flight, Ingenuity remained aloft for 77.4 seconds, flew 525 feet (160 meters), and landed about 440 feet (133.5 m) away from its companion, the Perseverance rover, according to a tweet from NASA’s Jet Propulsion Laboratory in California, which operates the helicopter.

The map to the right, annotated by me from the interactive map provided by the Perseverance team, shows the helicopter’s approximate new position, labeled #8 in green. The other green numbers show its previous landing spots after earlier flights.

The white line shows Perseverance’s travels through June 17th. The yellow dashed line shows their planned route over the next few months. Perseverance was just slightly north of Ingenuity on that date. It has likely traveled further south since then.

A detailed look at Russia’s suffering and shrinking space program

Link here. The article starts off outlining Russia’s deepening inability to produce the computer chips it needs for its space effort, acerbated by sanctions imposed against that country because of its invasion of the Ukraine. It then goes on to describe the program’s overall financial problems, including its shrinking commercial market share resulting in a significant drop in income.

The article’s conclusion is stark:

If Moscow is unable to reach a new space deal with Washington, it will need to reconsider its space policy. But Russia has little wiggle room to increase federal spending on space activities to boost the industry. For instance, the government’s space program for 2016–2025 received $11.1 billion in 2016–2020 and will obtain another $10.2 billion in 2021–2025. The federal program for launch sites (2017–2025) secured $1.4 billion in 2017–2020 and will take in a further $2.83 billion in 2021–2025 (Economy.gov.ru, 2016–2021). The 2012–2020 GLONASS program received almost $5.1 billion, and $6.45 billion more is planned for the GLONASS program in 2021–2030 (RBC, December 21, 2020). Thus, without an international cooperation deal, and as long as Western sanctions are maintained, prospects for Russia’s space industry look bleak.

Russia has recently been working to establish a partnership with China and its effort to build a space station and a lunar base. That partnership however is not likely to provide Russia with any cash, which means the deal is an empty one. While China will continue to proceed to the Moon, I doubt Russia will follow with much.

It has also been trying to rework its American partnership, with Rogozin acting alternatively as a good guy/bad guy in public declarations. Since Russia opposes the Artemis Accords, and the Biden administration is continuing the Trump administration’s demand that all partners in the Artemis program agree to these accords, those negotiations are not likely to get Russia much. Moreover, NASA policy today is to feed money to American private companies so that they can grow, not feed money to Russia so that it can prosper.

Until Russia starts allowing free competition and private enterprise, outside the control of Roscosmos and the government, do not expect much of this Russian bad news to change. While China might strictly supervise the goals of its private space companies, it still encourages them to compete and innovate, and even fail. Russia not only strictly supervises, it also forbids any new startups from forming, as they might do harm to already established players. The result is no new innovation, and no new products of any real value.

Zhurong’s travels during first three weeks on Mars

Zhurong's travels through June 11th
Click for full image.

The science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) today released a new image showing the path that China’s rover , Zhurong, has taken from its landing on May 14th through June 11th.

The photo to the right, cropped and reduced to post here, is that photo. If you look close you can see the rover’s track skirting the edge of the bright blast mark put on the surface by the lander’s engines during touchdown. Though my scale bar is approximate, it does show that in those four weeks the rover traveled about 150 to 200 feet. However, half of that distance was crossed in the five days from June 6th to June 11th (as shown by the two different MRO images at these links), which means the pace is picking up.

The rover’s nominal three-month mission ends in mid-August, only two months from now. However, none of us should be surprised if the mission gets extended for as long as the rover continues to function.

Update on attempts to bring Hubble back to life

Engineers have released an update on their attempts to bring Hubble out of safe mode that are indicating that they are honing in on the cause of the problem.

After performing tests on several of the computer’s memory modules, the results indicate that a different piece of computer hardware may have caused the problem, with the memory errors being only a symptom. The operations team is investigating whether the Standard Interface (STINT) hardware, which bridges communications between the computer’s Central Processing Module (CPM) and other components, or the CPM itself is responsible for the issue. The team is currently designing tests that will be run in the next few days to attempt to further isolate the problem and identify a potential solution.

This step is important for determining what hardware is still working properly for future reference. If the problem with the payload computer can’t be fixed, the operations team will be prepared to switch to the STINT and CPM hardware onboard the backup payload computer. The team has conducted ground tests and operations procedure reviews to verify all the commanding required to perform that switch on the spacecraft.

It appears that no matter what solution they arrive at, they will still require several days to test the solution to make sure it works. This update however is very hopeful, as it does appear they are locating the cause and have avenues for fixing it.

Hubble went into safe mode on June 13, which means it has now been out of operation for more than ten days.
