Study: Canada’s nationalized health killed nearly 1,500 Canadians waiting fruitlessly for treatment

11:07 am

Coming to your U.S. health plan soon! A new study has found that almost 1,500 Canadians died in 2018-19 waiting for a life-saving operation, sometimes years, because that nation’s national health system could not serve them.

The survey was also incomplete, covering only about half of Canada’s health system, which means the numbers are almost certainly higher. More significant, the Wuhan panic has made the situation worse.

Since the coronavirus pandemic began, there has been a drastic decline in potentially life-saving treatments being conducted by hospitals. According to figures from the Ontario Ministry of Health, between March 15 to September 29, treatments for breast cancer and prostate cancer have gone down 29% and 25% respectively. On average, the province has reported a total of 21% fewer cancer treatments in total.

Surgeries on children were also heavily impacted by the pandemic after reporting a decline of nearly 60%. In comparison, in 2019, 28,844 surgeries were performed on children, while in 2020 there were only 11,230.

But we need to save one life from COVID! One life! It doesn’t matter if thousands of others die from other illnesses, saving people from COVID comes first!

New Gaia data release tracks distance and motion of 1.8 billion stars

10:49 am

The European Space Agency (ESA) today released the third round of data from its Gaia satellite, designed to measure precisely the distance and motion of billions of nearby stars.

Gaia EDR3 contains detailed information on more than 1.8 billion sources, detected by the Gaia spacecraft. This represents an increase of more than 100 million sources over the previous data release (Gaia DR2), which was made public in April 2018. Gaia EDR3 also contains colour information for around 1.5 billion sources, an increase of about 200 million sources over Gaia DR2. As well as including more sources, the general accuracy and precision of the measurements has also improved.

This release also included the following discoveries:

  • The Milky Way’s outer regions beyond the Sun contain two populations of stars, one slowly dropping towards the galaxy’s plane, the second flying away quickly.
  • The first precise measure of the solar system’s orbit in the Milky Way
  • A more complete census of all stars within 100 parsecs of the Sun
  • A better map of the interaction between the Large Magellanic Cloud and the Milky Way, which also showed that the cloud does have a spiral structure

This precise data will take decades to digest, as past research has been based on only rough distance and motion estimates. Having precise data will change our approximation of each object’s brightness, which will also change much of what we assume about it.

ESA signs contract for 1st space junk removal

9:39 am

Capitalism in space: The European Space Agency (ESA) has now signed a contract with a private company, ClearSpace SA, for the first dedicated commercial mission to remove a piece of orbiting space junk.

ESA officials signed a contract with ClearSpace on Nov 13. to complete the safe deorbiting of a payload adapter launched aboard the second flight of the Arianespace Vega rocket in 2013.

Unlike traditional ESA contracts that involve the agency procuring and coordinating the mission, ClearSpace-1 is a contract to purchase a service: the safe removal of a piece of space debris. ESA officials said they intend this mission to help establish a new commercial sector led by European industry. The 86 million euros supplied by ESA will be supplemented with an additional 24 million euros ClearSpace is raising from commercial investors. Approximately 14 million euros of the privately-raised funding will be utilized for the mission, while the remaining 10 million will be set aside for contingencies, ESA spokesperson Valeria Andreoni told SpaceNews.

First, that the ESA has decided here to shift from running the mission and to merely being the customer buying the product from a private company is magnificent news. Europe has been, like NASA was in the 2000s, very reluctant to give up its total control in the design, construction, and launch of rockets and spacecraft. That they are now mimicking NASA’s own shift in the 2010s to this private model, as I outlined in detail in Capitalism in Space, means that ESA’s bureaucracy is finally coming around to the idea of freedom, capitalism, and private enterprise. What a thing!

Second, though this mission is commercial, it isn’t really a practical economic solution to the removal of most space junk. The contract will cost $104 million, plus the additional private capital ClearSpace has raised. None of this appears to include the launch cost. Yet, it will only remove one defunct object in orbit.

Such a technology will be useful for removing specific large pieces of space junk that pose a risk should they crash to Earth. It will not be economically useful for removing the small junk in orbit that threatens other working satellites and spacecraft. For that technology to be cost effective it will need to be able to clean up many objects on a single flight.

Space tourism balloon company raises $7 million

9:25 am

Capitalism in space: The space tourism balloon company Space Perspectives has now raised $7 million for the initial development of their Neptune stratospheric balloon, designed to take tourists up to about 30 miles for long flights at the edge of space.

The company, with about 15 employees currently, will use the funding to continue development of Spaceship Neptune, a stratospheric balloon system designed to carry people to an altitude of 30 kilometers. Such flights would give people an experience similar to some aspects of spaceflight, notably the view.

A first test flight of the system, without people on board, is scheduled for the first half of 2021 from the Shuttle Landing Facility at the Kennedy Space Center in Florida. “It will really take us through the concept of operations” of the system, Taber MacCallum, co-founder and co-chief executive of Space Perspective, said in an interview. “It allows us to jump into serious hardware testing.”

If all goes well, they plan to begin selling tickets next year as well, with the first commercial flight targeted for ’24. This funding round also likely puts the company ahead of its two Spanish competitors, who are presently tied up in litigation against each other.

The article also quotes company officials as lauding the FAA’s new revised licensing procedures, the first industry response I’ve seen to these new licensing procedures. The new rules [pdf] required a document 785 pages long (actually larger than the FAA’s first proposed revision), making it hard to determine their effect — for good or ill — without actually using them. This positive review by an industry user is a very positive sign.

Starship 9-mile-high flight now set for no earlier than December 4th

9:13 am

Starship on launch pad
Click for LabPadre live stream from which this still was captured.

Capitalism in space: SpaceX has now scheduled the first 9-mile-high flight of its 8th Starship prototype for either December 4th, 5th, or 6th.

On Wednesday, the Federal Aviation Administration issued a temporary flight restriction for SpaceX to conduct a Starship launch from its facility near Boca Chica Beach in South Texas. The notification allows the company to attempt a Starship hop on Friday, Saturday, or Sunday, between the hours of 9am EST (14:00 UTC) and 6pm EST (23:00 UTC) daily. SpaceX must still obtain a launch license from the FAA for this flight.

The company’s founder and chief engineer, Elon Musk, has said SpaceX will attempt to fly Starship to an altitude of 15km to demonstrate the performance of three Raptor engines over the course of several minutes. The company’s previous flights to about 150 meters, in August and September, used a single Raptor engine.

This higher flight profile will take Starship above nearly 90 percent of Earth’s atmosphere, which will allow the company to do several new tests: assess the performance of body flaps on Starship, transition from using propellant from the main fuel tanks to smaller ones used for landing burns, and test the vehicle’s ability to reorient itself for returning to the launch site.

Look closely at the screen capture of Starship above. Note how there is no launch tower at all, and that the launchpad is simply a platform on which the ship sits. This lack indicates two things. First, the ship’s large diameter gives it a much lower center of gravity compared to all other rockets. It doesn’t need the launch tower for support. This is why SpaceX can move it back and forth from the assembly building on the equivalent of a large flatbed truck.

Second, the lack illustrates SpaceX’s lean and mean engineering style. When this spacecraft finally launches to orbit on top of a Super Heavy first stage, it will certainly need a launch tower, not so much for support but to fuel it and allow access to and from while on the launchpad. None of this infrastructure however is needed now for the ongoing development work. Why waste money and time building it when they don’t yet know the exact specifications of the final rocket itself?

SpaceX is taking advantage of the first point to do the second, thus speeding development and lowering its cost.

Chang’e-5 completes sample collection; lifts off from Moon

8:57 am

UPDATE: The official state-run Chinese press has announced that the ascent capsule with the lunar samples has lifted off from the Moon. The rendezvous and docking is next, which is likely the most difficult technical task for the autonomous unmanned probe. No word yet on when that will occur.

Original post:
——————

The new colonial movement: China’s Chang’e-5 lunar lander has completed its sample collection on the Moon, and is set to lift-off sometime today for a rendezvous and docking with its return vehicle in lunar orbit.

The milestone signaled the start of the mission’s return voyage, which includes an ambitious series of automated maneuvers to blast off from the lunar surface Thursday and rendezvous with an orbiter circling the moon. Chang’e 5 will attempt the first-ever docking between two robotic spacecraft in lunar orbit, then transfer the moon rock container into the return craft.

If all goes according to plan, Chang’e 5’s sample container should re-enter Earth’s atmosphere and parachute to a landing in China’s Inner Mongolia region around Dec. 16.

If successful, this will the ninth spacecraft to bring samples back from the Moon, and the first since the 1970s. It will also firmly establish China as a major space power that is presently competitive to the U.S. and has also bypassed Russia completely. Even though it is likely they stole much of the technology for doing such planetary missions, China’s engineers have done a good job of refining and improving the engineering, as shown by the number of firsts being achieved by this Chang’e-5 mission.

On the radio

2:07 pm

I will be doing a quickly scheduled appearance with Robert Pratt at 5 pm (Central) today on his Pratt on Texas radio network, airing across the Lone Star State. You can listen live here or from an affiliate station available here.

The interview is scheduled for 30 minutes, but it could go longer. The subject will be the muzzle of oppression that so many Americans are now willing to put on their faces.

First images from Chang’e-5 on the Moon

2:01 pm

Panorama of Chang'e-5 landing site
Click for full image.

The new colonial movement: China’s state-run press has now released several images taken by Chang’e-5 on the lunar surface, including movies showing the landing and the ongoing digging operations.

The photo to the right, cropped and reduced to post here, is part of a fisheye panorama of the entire landing site. I have cropped it to show only the central part. Except for the distant mountain, the terrain is very flat, which is not surprising as this is the Ocean of Storms mare.

Note however how deep the landing pad is pressed into the ground. This gives a sense of the dust layer that covers the surface.

The link above, as well as this link, show additional images as well as the two movies.

Take off is next, followed by the autonomous rendezvous and docking in lunar orbit with the craft that will bring the sample capsule back to Earth sometime around December 16.

Sagging cliffs on Mars

Sagging escarpment on Mars
Click for full image.

Cool image time! On Mars things change, but not like on Earth because the atmosphere is not as thick and there is no flowing water. The photo to the right, rotated, cropped, reduced, and annotated to post here, gives a good example of that slow change. The image was taken on August 29, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows the high escarpment that in this one place separates the planet’s southern cratered highlands from the transition zone down to northern lowland plains.

In this spot that escarpment, approximately 4,000 feet high, shows signs of avalanches and sagging. In the upper steep section, I point to what looks like a dust avalanche that wiped the slope clear of rough terrain as it rolled downhill. At the bottom of the cliff a large section has separated away. Since this cliff is located at 28 degrees north latitude and is in the midst of the chaos terrain regions I like to dub glacier country, it is very possible that this large section is actually buried glacial ice that in shifting down slope cracked, separating the lower section from the upper.

This particular location is east of an area dubbed Nilosyrtis Mensae (where there is a lot of evidence of glaciers and frozen ice), and about 650 miles north of Jezero Crater, where the rover Perseverance will land on February 18, 2021.

Rocket Lab provides detailed update on successful recovery of first stage after splashdown

9:20 am

Capitalism in space: Rocket Lab has now provided a detailed update on the company’s first successful recovery of the first stage of their Electron rocket from the ocean on November 19, 2020.

Much of the press release reiterates what the company CEO Peter Beck said on November 24th, but in much better engineering detail. Key finding:

The stage held up remarkably well – not bad after experiencing the trip to space and back in just 13 minutes. The carbon composite structure was completely intact. As expected, the heatshield on the base of the stage suffered some heat damage during re-entry. It was never designed for this load case, but before we strengthen the heat shield we wanted to see just how much heat it could take unchanged. With a wealth of data on this now, our team has already started working on upgrades for future recovery missions.

They also intend to re-fly some components from that stage. I have embedded below the fold their footage taken during from the inside of the first stage during its splashdown.

The next recovery attempt in early ’21 will also splash down in the ocean. Before they attempt a helicopter snatch from the air they want gather more data.
