Vulcan found?

9:51 am

Scientists have found a super-earth orbiting 40 Eridani-A, a star located sixteen light years away and proposed by Gene Roddenberry in 1991 as the home star for his race of logical Vulcans.

It turns out the letter authors’ prediction was right — a world really does orbit the primary star of the three-star 40 Eridani system. (Whether it’s home to a logic-based alien society, though, is anyone’s guess!)

The world is a super-Earth, the most common type of planet in the galaxy (though a type that’s missing from our solar system). At twice Earth’s radius and eight to nine times its mass, 40 Eridani b sits on the line that divides rocky super-Earths from gaseous ones. The planet orbits its star every 42 days, putting just inside the system’s habitable zone — in other words, where it’s nice and hot. At 16 light-years away, it’s the closest super-Earth known and therefore a good potential target for followup observations.

The discovery was made by a survey taking place using a relatively small telescope right here in the Tucson area, on top of Mount Lemmon. Most cool!

Instrument on GRACE-FO fails

9:45 am

The U.S/German science two-satellite constellation, launched in May, has not gathered any science data since July because one instrument on one satellite has shut down.

It appears the problem is related to an electrical problem. The article provides little information, though they say they will switch to a back up system later this month. I wonder why this has taken so long.

The article at the link calls this “a glitch.” That is a lie and bad journalism. Any failure that shuts down a spacecraft for months and requires the use of a back up is a major failure, not a mere “glitch.” I wish news organizations would stop using that word, as it only exists to help minimize the seriousness of a problem.

Air Force estimates Space Force cost at $13 billion for first 5 years

9:38 am

Pork! Air Force has now released its first estimate for establishing a Space Force, with an estimated cost of $13 billion for first five years.

A copy of the Air Force memo was obtained Monday by The Associated Press. The memo says the first-year cost of a Space Force would be $3.3 billion, and the cost over five years would be an estimated $12.9 billion.

As I have said, this is nothing more than pork. At this stage all that needs to happen is a reorganization that would put all space activities in a single office in the Air Force. This is also what the Air Force has wanted to do. Creating a whole new military branch at this time is overkill, and will merely result in too much bureaucracy, for only one reason, to spend money.

Kenya creates space agency

9:32 am

The new colonial movement: Kenya today announced the official establishment of its own space agency, the Kenya Space Agency Board (KSAB).

KSAB was established by President Uhuru Kenyatta through a March 2017 gazette notice and will be headed by the Kenya Defence Forces’ Major General (Rtd) James Aruasa.

The array of KSAB’s responsibilities include co-ordinating space-related activities, recommending national space policies and establishing centres of excellence in space science.

It appears to me that there a power struggle is going on in Kenya over space, with the wrong people winning. A university team recently built the nation’s first cubesat, getting it launched as a secondary payload. This space board however seems entirely run by the government and its military. I fear that this turf war is going to squelch any future Kenyan space development.

Curiosity fails again to drill into Vera Rubin Ridge

9:13 am

For the third time Curiosity has failed to drill into the rock on top of Vera Rubin Ridge.

Last night we learned that our drill attempt on “Inverness” was not successful, reaching only 4 mm into the rock.

The only successful drill attempt on the ridge occurred when they moved down off the top of the ridge to a slightly lower geological layer.

They are moving Curiosity to another candidate drill site on the ridge, where they will try again. While they imply in their reports that it is solely the hardness of the ground that is stopping them, I still wonder if the improvised drill technique, using the robot arm to push down rather than the drill’s jammed feed mechanism, is partly to blame. I would think that they have placed limits on how hard the arm can push to protect it.

SpaceX’s first BFR passenger is Yusaku Maezawa, owner of Japanese fashion company

7:28 pm

Yusaku Maezawa

Capitalsm in space: SpaceX’s first BFR passenger will be Yusaku Maezawa, the owner of Japanese fashion company, shown on the right.

Maezawa began his statement by echoing John Kennedy with these words, “I choose to go to the Moon.” He purchased the entire first flight, and will invite six to eight artists to join him on the flight and ask them to create art afterward inspired by the flight. They are aiming for a launch in 2023.

BFR

Musk began the presentation tonight with an overview of the status of BFR, noting that they plan unmanned test launches before putting humans on the rocket. The image an the right shows the habitable upper stage.

During the question and answer session after the announcement Musk was asked questions about the present stage of BFR design, and whether it has been finalized. He said they plan “a lot of test flights” and are aiming for first orbital flights in 2 to 3 years, “if things go really well.”

Musk made it clear that Maezawa chose SpaceX for the flight, rather than the other way around. Musk also said that Maezawa was paying them a lot of money for the flight, though they were not going to reveal the amount. Musk did note that the price was not trivial, and that Maezawa has already made a significant deposit. Maezawa had first approached them for a Dragon/Falcon Heavy flight, but because of the limitations of of those spacecraft, they decided it better to go with the bigger rocket.

Musk noted that the first test hops of the upper stage to test its landing capabilities will take place at Boca Chica in Texas. The launch site for the orbital missions is not yet decided.

Musk estimated that the cost for developing BFR is going to probably be around $5 billion, which he also noted rightly is quite small for this kind of project. He also said that right now they are only devoting 5% of SpaceX’s resources to this mission. As they complete the crew Dragon project, they will then begin to shift resources to BFR. He estimated that will happen sometime late next year.

Overall, it strikes me that they really do not have all the details yet worked out, with the rocket or their flight schedule. As Musk openly admitted when asked if they are sure about the schedule, “We are definitely not sure.” This is not necessarily a bad thing, since it is often better to keep an open-mind in planning something this ambitious. At the same time it tells us not to expect any of this to happen, as described.

One final point: Musk at one point said he wants a base on the Moon. “It’s 2018, why don’t we have a base on the Moon?” To me, this was an almost direct dig at NASA’s Gateway/FLOP-G project, which isn’t a base but locks us in lunar orbit. Musk was being very careful to avoid criticizing NASA, his biggest customer, but anyone who knows what is going on will quickly recognize that BFR is in direct competition with SLS/Orion/Gateway.

Based on SpaceX’s history, going from first orbit flight to flying the world’s largest rocket in only ten years, I am very confident that this company could get that first base on the Moon, long before NASA even gets Gateway launched.

A Trip Through Victorian Paris, France

6:00 pm

An evening pause: This footage was taken from 1896 to 1900 in Paris, and has been cleaned up and shown here at the correct speed with sound added to match the visuals. What you will see:

0:08 – Notre-Dame Cathedral (1896)
0:58 – Alma Bridge (1900)
1:37 – Avenue des Champs-Élysées (1899)
2:33 – Place de la Concorde (1897)
3:24 – Passing of a fire brigade (1897)
3:58 – Tuileries Garden (1896)
4:48 – Moving walkway at the Paris Exposition (1900)
5:24 – The Eiffel Tower from the Rives de la Seine à Paris (1897)

What strikes me is the dignified behavior and dress of the people. We are of course mostly looking at Paris’s high class streets, but nonetheless there is something in the culture that requires them to behave as civilized as they can.

Trump unclassifies FISA warrants, interviews; orders release of unredacted FBI text messages

3:53 pm

Trump has today unclassified both the FISA Carter Page application and the FBI interviews connected with that application. He also ordered the release, unredacted, of all FBI text messages of James Comey, Andrew McCabe, Peter Strzok, Lisa Page, and Bruce Ohr.

This information I think is going to demonstrate that the certain people at the FBI have been running an anti-Trump/pro-Democratic Party operation, concocting a false claim of Russian-Trump collusion in order to remove a duly elected President. Moreover, comparing the previously released redacted text messages with the unredacted messages is almost certainly going to reveal that someone at the FBI has acting to obstruct the investigation.

I wonder if anyone will ask the question “Who?”

I should also point out that Trump himself could have read these documents whenever he wanted. He doesn’t need to declassify them to see them, and form judgements from them. Moreover, the redactions only apply to the public, not to Trump. He could have seen this anytime, and acted immediately, if he had chosen.

Instead, he chose to wait and wait, and then release this now, at a moment when all eyes are aimed at the fake scandal being perpetrated by the Democrats against his Supreme Court nominee.

Cryo-volcanism had less influence on shaping Ceres than predicted

10:23 am

The uncertainty of science: A careful analysis of the Dawn data has found that though cryo-volcanism has occurred repeatedly on Ceres, it had less influence on the dwarf planet’s surface than previous models had predicted.

At the same time, the data also suggests that Ceres has been more active throughout its history than predicted. They found about 22 domes that are apparently past cryo-volcanoes that have flattened out.

“Given how small Ceres is, and how quickly it cooled off after its formation, it would be exciting to identify only one or two possible cryovolcanoes on the surface. To identify a large population of features that may be cryovolcanoes would suggest a long history of volcanism extending up to nearly the present day, which is tremendously exciting,” said Sizemore. “Ceres is a little world that ought to be ‘dead,’ but these new results suggest it might not be. Seeing so much potential evidence for cryovolcanism on Ceres also lends more weight to discussions of cryovolcanic processes on larger icy moons in the outer solar system, where it’s likely more vigorous.”

SpaceX announcement of first passenger for Lunar BFR

9:43 am

Capitalism in space: SpaceX will have a webcast today at 6 pm (Pacific) to announce the name of the first passenger to fly on a lunar mission using their Big Falcon Rocket (BFR).

The embed of that webcast is below, so if you wish you can watch right here.

Note that my initial post mistaken said this was happening at 6 pm Eastern time. That was an error.

Statement about closure of solar observatory

5:05 pm

AURA, the university consortium that operates the closed Sunspot Solar Observatory in New Mexico, issued a statement today about that closure.

AURA has been cooperating with an on-going law enforcement investigation of criminal activity that occurred at Sacramento Peak. During this time, we became concerned that a suspect in the investigation potentially posed a threat to the safety of local staff and residents. For this reason, AURA temporarily vacated the facility and ceased science activities at this location.

The decision to vacate was based on the logistical challenges associated with protecting personnel at such a remote location, and the need for expeditious response to the potential threat. AURA determined that moving the small number of on-site staff and residents off the mountain was the most prudent and effective action to ensure their safety.

In light of recent developments in the investigation, we have determined there is no risk to staff, and Sunspot Solar Observatory is transitioning back to regular operations as of September 17th. Given the significant amount of publicity the temporary closure has generated, and the consequent expectation of an unusual number of visitors to the site, we are temporarily engaging a security service while the facility returns to a normal working environment.

We recognize that the lack of communications while the facility was vacated was concerning and frustrating for some. However, our desire to provide additional information had to be balanced against the risk that, if spread at the time, the news would alert the suspect and impede the law enforcement investigation. That was a risk we could not take.

This news release, while still very vague about the criminal investigation, implies that there was a dangerous criminal suspect on the mountain that federal officials were pursuing, and they evacuated to protect their employees.

This explanation still leaves serious questions. Why for example were local police kept in the dark about this investigation? It makes no sense not to include them, unless they might be a target of the investigation, something that in this case does not appear to be true.

Also, if there was a criminal on the mountain, secrecy is not really an effective way to catch him. It might make sense, but they have not provided us any information that would explain this.
