Norway inaugurates its Andoya spaceport

9:39 am

Map of Norway showing Andoya

Norway yesterday announced the opening its new Andoya spaceport in the far north of the country, where it hopes will become a hub for the emerging new commercial launch industry.

The location is indicated by the map to the right, in the Arctic and farther north than any other planned spaceport, making it excellent for satellites going into polar orbit.

The launch base, which eventually will have several launch pads, was built by Norwegian public company Andoya Space, on a site which until now has only been used for firing suborbital scientific experiment rockets.

Spectrum, a two-stage craft capable of carrying up to one tonne and developed by the German start-up Isar Aerospace, is scheduled to be the first rocket to be launched from island which is located near the idyllic Lofoten archipelago.

If Norway’s government works better than Great Britain’s in issuing launch permits, this spaceport will steal all business from the UK’s own two spaceports being built in Scotland.

Iceland signs Artemis Accords

9:29 am

Though no press announcement was ever released, it appears that Iceland signed the Artemis Accords sometime in October, according to small mention in the the press release announcing the signing of the Netherlands.

The mention was so small I missed it. In fact, so apparently did NASA, as Iceland did not issue its own press release. The U.S. likely found out about the signing through private diplomatic communications.

This brings the total number of nations now part of this American space alliance to thirty-one, as follows: Argentina, Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, Germany, India, Iceland, Israel, Italy, Japan, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

Lucy discovers second small asteroid orbiting Dinkinesh

9:15 am

Dinkinesh as seen by Lucy

During its November 1, 2023 fly-by of the asteroid Dinkinesh the asteroid probe Lucy surprisingly discovered that the asteroid was actually a binary, with a second smaller asteroid orbiting it.

The picture to the right, cropped, reduced, and sharpened to post here, was taken by Lucy’s camera within a minute of the probe’s closest approach of 270 miles. The second asteroid is partly blocked by Dinkinesh.

In the weeks prior to the spacecraft’s encounter with Dinkinesh, the Lucy team had wondered if Dinkinesh might be a binary system, given how Lucy’s instruments were seeing the asteroid’s brightness changing with time. The first images from the encounter removed all doubt. Dinkinesh is a close binary. From a preliminary analysis of the first available images, the team estimates that the larger body is approximately 0.5 miles (790 m) at its widest, while the smaller is about 0.15 miles (220 m) in size.

The nature of both asteroids appears to lie between a rubble pile (like Bennu) or a solid smooth rock (like Eros), suggesting we are now beginning to see aspects of the overall evolution of asteroids over time.

So far only a few images from this fly-by have been released. It will take a week for the rest of the data from the fly-by to beamed back to Earth. However, these images prove that the prime purpose of this fly-by was successful, proving that Lucy is operating as planned, able to point, manuever, and obtain its data during such a fly-by. When it arrives in the Trojan asteroids in 2027 it will be able to do its prime mission.

The goal of Hamas (and its supporters) is to kill all Jews

1:52 pm

Map of Hamas massacres on October 7, 2023

It shouldn’t be necessary to have to spend any time proving the bigoted, Jew-hatred of Hamas, considering the horrible murder of about 1,400 Israeli men, women, children, and babies on October 7, 2023, with many burned alive, decapitated, tortured, and raped. Their actions that day were right out a Nazi handbook, and any sane decent human being should be able to easily see it.

And yet, it sadly is necessary, because that barbaric behavior is now being justified and excused by too many very ignorant people, not just in Gaza and the West Bank but worldwide, even in the most famous colleges in the U.S.

The map to the right is a good first data point. Hamas officials have gone on television and arrogantly claimed “We did not have any intention or decision to kill any civilians.” This lie is proven unambiguously by the map. The red dots indicated the locations of bodies. The black dots those who have been kidnapped. The locations of both illustrate how well planned this Hamas operation was, and its outright intention to kill civilians. These are not military facilities, but Jewish settlements where civilians live. Hamas mapped those locations, and targeted them precisely, including the Re’im music festival, which was a specific event and contained nothing but civilians.

This map, titled “Mapping the Massacres”, is available online, and provides close-ups of the murder maps for each massacre. If go to the link and click on the “Walkthrough” button on the bottom right, it will not only zoom in step-by-step to each massacre, it then provides detailed descriptions of what happened at each location.

During landing Shenzhou’s single parachute appeared damaged

10:01 am

A closer look at imagery during the descent by parachute of China’s manned Shenzhou capsule, bringing three astronauts back from Tiangong-3 after a five month mission on October 31, 2023, shows that the capsule’s single parachute had a ripped hole.

In some of the footage, a patch of blue sky can be seen through the red-and-white-banded parachute. Inside the capsule were Shenzhou 16 mission commander Jing Haipeng and crewmates Zhu Yangzhu and Gui Haichao — the latter pair returning to Earth after their first mission to space.

Such a sizable hole, which was visible before a white cloud of vented propellant left the Shenzhou capsule, has not been reported during earlier missions. It did not, however, seem to affect operations.

The landing however was very rough, with the capsule tumbling several times after hitting the ground.

Considering that China presently as three astronauts on Tiangong-3 that have to come home in their own Shenzhou capsule, using this same parachute system, finding out what happened seems imperative. Developing its next generation larger capsule, which will return using three parachutes, also appears essential.

Senate passes bill that gives NASA and Commerce responsibility for removing space junk

9:27 am

The Senate on October 31, 2023 passed a bill that requires NASA to develop several space junk removal projects while giving the Commerce department the responsibility of identifying what space junk needs to be removed.

The central part of the bill would direct NASA to establish an active debris removal program. Tnat includes creating “a demonstration project to make competitive awards for the research, development, and demonstration of technologies leading to the remediation of selected orbital debris.” It would also require NASA to enter into a partnership to fly a demonstration mission to remove debris.

The debris that could be removed by those demonstrations would come from a list developed by the Department of Commerce to identify debris “to improve the safety and sustainability of orbiting satellites and on-orbit activities.” The Department would also lead work on best practices for space traffic coordination. The bill directs the National Space Council to lead an update of the federal government’s Orbital Debris Mitigation Standard Practices.

Though unstated, this bill appears to be a direct slap at the FCC’s effort under the Biden administration to claim the power to regulate space junk, despite its lack of statutory authority to do so. In fact, the Senate underlined that slap in the face by also passing a bill that demanded the FCC streamline its regulatory overreach rather than expand it.

Neither bill is law yet, and it is unclear whether the House will agree to either. The Senate has sent the space junk bill to the House previously without passage.

A seasonal map of the cloudy parts of Mars

9:10 am

Seasonal map of the cloudy parts of Mars
Click for original image.

Though Mars’ very thin atmosphere (1/thousandth that of Earth) is generally clear, it does have clouds that come and go. A project begun in 2022 using citizen scientists to identify these clouds and the seasons they appear the most, dubbed Cloudspotting on Mars, has now published its first paper, available here.

The graph to the left, Figure 9 in the paper, shows two seasonal Mars maps, one indicating the daytime seasonal frequency of clouds and the other their nightime frequency. From the paper:

The seasonal evolution of all clouds as a function of latitude for both daytime and nighttime are shown in Fig. 9. During the clear season until [mid-summer in the northern hemisphere] … there are several regions where clouds occur frequently: in the equatorial region (annotated as 1), at mid-latitudes (2), in the southern polar region (3), and to a lesser extent in the northern polar region [at the start of summer]. From [late fall to mid-autumn in the north], daytime clouds occur primarily at mid-latitudes, but are observed at nearly all latitudes between 70°S and 60°N (4). At night, there is one broad population from 30°S to 30°N (clouds are more frequent in the equatorial region at night), but [in autumn], clouds occur frequently between 30°N and 50°N as well. [In mid-spring] the number of observed nighttime clouds increases in the southern hemisphere, especially near 50°S. There is a strong decrease in the number of peaks just before [the late northern autumn and the late southern sping] at nearly all latitudes except around 50°S and 20°N at night. [Once northern winter arrives], clouds are observed between about 60°S and 60°N as well as both polar regions, although nighttime clouds between 0°N and 30°N occur relatively less frequently.

The low-latitude clouds during the clear season (1), which are observed more frequently at night, occur at high altitudes, 65–80 km during the day and 55–70 km at night; this is the aphelion equatorial mesospheric cloud population studied in depth by Slipski et al. (2022) and in which previous observations have spectrally confirmed CO2-ice.

Martian seasons

The bracketed words indicating seasons above replace the longitudal numbers the scientists use to indicate the seasons, and are used on these two graphs. The figure to the right shows what the longitude numbers represent in the graphs’ X-axis.

The project continues if any of my readers want to join in.

Space Force awards SpaceX and ULA new launch contracts worth $2.5 billion

8:37 am

Space Force yesterday awarded both SpaceX and ULA new launch contracts worth $2.5 billion and totaling 21 launches over the next two to three years.

The final batch of assignments were split almost evenly, according to Col. Doug Pentecost, the deputy program executive officer of the Space Force’s Space Systems Command. ULA received 11 missions, valued at $1.3 billion, and SpaceX received 10 missions, valued at $1.23 billion.

Space Systems Command said the missions are scheduled to launch over the next two to three years. ULA, a joint venture of Boeing and Lockheed Martin, will use its soon-to-debut Vulcan rocket for the 11 missions, while SpaceX will fly seven missions with its Falcon 9 rocket and three missions with its Falcon Heavy rocket.

For SpaceX this award is no surprise. The ULA contract is more puzzling. Supposedly the Space Force was not going to award any launch contracts for ULA’s new Vulcan rocket until it successfully launched twice and was certified by the military as operational. Yet, it has now awarded ULA this contract for Vulcan launches. Has the military awarded the contract on a contingency basis? What happens if Vulcan has a failure on one of its first two launches?

The Space Force’s present arrangement limits bidding for launches to just these two companies. If Vulcan fails will it open bidding to other companies, or will it transfer launches to SpaceX?

The Netherlands signs Artemis Accords

8:26 am

Confirming what it announced in early October, the Netherlands yesterday officially signed the Artemis Accords, becoming the thirtieth nations to join.

The full list of signatories to the Artemis Accords is now as follows: Argentina, Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, Germany, India, Israel, Italy, Japan, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

We now have the rough outline of the national alliances that will compete with each other in space. On one hand are the nations above, generally from the west with a larger focus on private enterprise and ownership. On the other hand are the authoritarian nations, led by China and Russia with a few failed communist nations like Venezuela.
