  • European startup The Exploration Company raises $44 million to develop reusable spacecraft

    • They hope to do fly a small demo prototype this year. Jay describes the future planned fullscale spacecraft: “The vehicle is called Nyx, I guess it was named after the Greek Goddess of the night. From the article: ‘Nyx would be able to send 4,000 kilograms to orbit for up to six months, and bring 2,600 kilograms back down for 20,000 euros per kilogram.'”

Dramatic layers in Valles Marineris

Dramatic layers in Valles Marineris
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and sharpened to post here, was taken on December 28, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows one tiny section of the interior slope of the giant Martian canyon Valles Marineris.

The while layers are not made of frost or ice, because they are light tan, as per the color image. Thus, the alternating layers of dark and light indicate different layering events. The dark layers are probably major lava flood events with a lot of dark ash intermixed, while the tan layers were flood lava events with little dark ash.

The dark lines that cut across these layers are ripple dunes formed from dust that has accumulated inside Valles Marineris.

Today’s blacklisted Americans: Catholic students kicked out of Air & Space museum for wearing pro-life hats

The evil hat that Air & Space banned
The evil hat that Air & Space officials banned

They’re coming for you next: A dozen Catholic students, having just attended the March for Life event on January 20, 2023 in Washington, found themselves being chased from the Smithsonian Air & Space Museum because they were all wearing hats with a pro-life message.

According to their lawyer,

Once in the museum, they were accosted several times and told they would be forced to leave unless they removed their pro-life hats. The group all wore the same blue hat that simply said, “Rosary PRO-LIFE.” Other individuals in the museum were wearing hats of all kinds without issue.

The museum staff mocked the students, called them expletives, and made comments that the museum was a “neutral zone” where they could not express such statements. The employee who ultimately forced the students to leave the museum was rubbing his hands together in glee as they exited the building.

According to the students and their parents, the kids were all wearing the same hats in order to find each other in the crowds.

When asked by the press about this incident, the museum responded as follows:

Fire in South Korean rocket facility

9:55 am

South Korea today reported that a fire had broken out in its Naro Space Center during work on a turbopump for a next generation rocket.

The fire started at 3:25 p.m. Tuesday at the Naro Space Center in the country’s southern coastal village of Goheung and was extinguished about an hour later, according to the Ministry of Science and ICT. The ministry said some experimental equipment was affected by the fire but reported no injuries.

The fire broke out while researchers were conducting an experiment to develop a 10-ton turbopump that injects fuel into an engine for a new space rocket, codenamed KSLV-III.

The KSLV-III will be an upgrade of the KSLV-II, also called Nuri, which has a launch scheduled right now in May. The KSLV-III is part of a $1.6 billion government project to develop this new rocket by 2032.

Diesel fuel spill at Air Force surveillance facility on Hawaiian mountaintop

9:49 am

The Air Force reported today that about 700 gallons of diesel fuel spilled out on January 29, 2023 at Air Force’s surveillance telescope facility on top of Haleakala on the island of Maui.

The spill occurred at the Maui Space Surveillance Complex, which tracks satellites and space debris using several telescopes atop Haleakala, a dormant volcano. “Due to a mechanical issue, a diesel fuel pump for an on-site backup generator failed to shut off” Sunday night, the Air Force said in a news release.

At about 8 a.m. Monday, maintenance personnel discovered the failure and shut off the transfer pump, the Air Force said.

Since 2021 the military has had two other accidents at different Hawaiian facilities. Considering the hostile political atmosphere there for any facility not run by “native Hawaiians”, this new fuel spill could not have come at a worse time. Expect pressure to mount to remove this facility.

ISRO completes investigation into failure of its SSLV rocket on first launch

9:40 am

India’s space agency ISRO today released the results of its investigation into the launch failure of its SSLV rocket on its first flight in August 2022.

The investigation revealed that there was a vibration disturbance for a short duration on the Equipment Bay (EB) deck during the second stage separation. SSLV is a three-solid-stage launch vehicle unlike the PSLV, which is a four-stage rocket. The vibration affected the Inertial Navigation System (INS), resulting in declaring the sensors faulty by the logic in the Fault Detection & Isolation (FDI) software.

In plain English, it appears the vibration caused a failure in the inertial navigation system, thus resulting in the premature engine shutdown of the fourth stage.

According to the report, the problem has been fixed and the next SSLV launch is now tentatively scheduled for February 9, 2023.

South Korea officially cancels Russian launch contract, signs Vega-C instead

9:31 am

South Korea yesterday officially announced that it has canceled a Russian contract that was supposed to use an Angara rocket to launch a multi-purpose satellite last year and signed a deal with Arianespace to use the Vega-C rocket instead.

The cancellation appears directly because of the sanctions against Russia due to its invasion of the Ukraine. Picking the Vega-C as a replacement at this moment however seems a strange choice, considering its last launch was a failure and it has failed three times in the last eight launches. I suspect Arianespace gave South Korea an extremely good price.

Meanwhile, South Korean officials still seem willing to continue another Russian launch contract, using a Soyuz-2 rocket launching from Kazakhstan. According to the article, officials are right now merely negotiating a launch date.

SpaceX successfully launches 53 Starlink satellites

1:08 am

Using its Falcon 9 rocket, SpaceX early this morning successfully launched from Cape Canaveral another 53 Starlink satellites.

This was the 200th Falcon 9 launch. The first stage, making its fifth flight, landing successfully on a drone ship in the Atlantic. The two fairing halves completed their sixth and seventh flight respectively. At of this writing the satellites themselves have not yet been deployed.

The 2023 launch race:

8 SpaceX
5 China
1 Rocket Lab
1 Japan

American private enterprise now leads China 9 to 5 in the national rankings, and the entire world combined 9 to 6.

Petula Clark – Sign Of The Times

6:01 pm

A evening pause: This performance, almost certainly lip-synced, is from the Ed Sullivan Show in 1966. It is absolutely worth watching, not only because the song is good, but the set, costumes, and dance choreography will give those too young to have lived in the 1960s a real sense of the crazy no-holds-barred culture of that time. People were willing and free to try anything.

Buried silo on Mars?

4:50 pm

A buried silo on Mars?
Click for original image.

Cool image time! The picture to the right, rotated and cropped to post here, was taken on December 31, 2022 by the high resolution camera on Mars Reconnaissance Orbiter.

The headline is pure silliness, and should not be taken seriously. However, the geological feature is intriguing nonetheless. Its almost perfect circular shape suggests a partly buried or eroded crater, except that its consistent thickness, almost like a wall, does not match what the rims of any crater should look like. Crater rims are made up of ejected material pushed out during impact, and thus always include some chaotic features.

My guess is that this circular feature is volcanic in nature. Maybe this was once a caldera, and the circle indicates a final vent from which lava extruded and then solidified.

At least, that’s my story.

The feature is located in the southwest quadrant of Hellas Basin, the basement of Mars, at 49 degrees south latitude. While this also suggests that ice might help explain this, we must also remember that much of the geology in that basin remains unexplained. Thus, there is no reason not to add one more feature to the list.
