Jupiter in 3D

Cool image time! Using images from Juno, a citizen scientist going under the nom de plume YobiRoby has created the height map image to the right, showing three-dimensionality of the cloud surface of Jupiter.

Though they provide no details to go with this image, it appears it is centered on Jupiter’s Great Red Spot, the larger of the two big storms that are visible. While the smaller storm appears raised like a mound above the surrounding cloudtops, the Great Red Spot instead appears to be a mound that is depressed below the cloudtops.

Russian cosmonauts refuse to donate sperm for space research

9:21 am

According to one Russian scientist, Russian cosmonauts have been refusing to donate their sperm for a space research project to be launched on that country’s next Bion-M satellite in 2023, making that research impossible.

“We have been unsuccessful in getting the Coordinating Scientific & Technical Council responsible for approving experiments on the Russian segment of the ISS to approve such a routine procedure as the handover of seminograms by cosmonauts,” [Dr. Irina Ogneva, lab chief at the Institute of Cell Biophysics outside Moscow] explained. “We are consistently impeded by objections of a moral, psychological and ethical nature, and can’t find any volunteers among the cosmonauts,” she added.

According to the scientist, the mere mention of the idea of getting the male biomaterial in conditions of space merely “causes everyone to smile” and reject it.

Ogneva also is quoted as proposing that Russia also consider a project for giving birth to the first child in space.

“We are mindful of the fact that we were always first in space and in many areas remain the leaders. Therefore, it would be nice if the first human being born in space were a Russian citizen. But we should place care for the individual, not patriotic populism, at the forefront of our efforts,” Ogneva stressed.

According to the scientist, while it remains too early to formally set the mission of having a child in space, formulating the goal is already possible. Along with technical questions, there are moral and ethical issues which remain to be resolved, since a live birth would essentially constitute an experiment involving a human embryo.

The difficulties, both moral and ethical, for that first space childbirth, are so daunting that I expect it will only happen in one of two ways. Either it will occur in an unplanned manner, with a female astronaut getting pregnant and giving birth while on a mission where a retreat to Earth will be impossible, or it will occur because some totalitarian government, such as China or Russia, will force it on a woman.

It will happen eventually, however, and when it does, we will find out the limits of our ability to populate space. We might find that only in a gravity well can humans reproduce. Or not.

The unknowns are quite striking.

SpinLaunch gets first launch contract, from Defense Department

9:08 am

Capitalism in space: The smallsat launch company SpinLaunch has gotten its first launch contract from a division of the Defense Department.

In a statement today (June 19), SpinLaunch announced that it has received a “launch prototype contract” from the U.S. Department of Defense under a deal arranged by the Defense Innovation Unit. The Long Beach, California-based company aims to launch its first test flights in early 2020 from Spaceport America in New Mexico.

SpinLaunch is developing a “kinetic energy-based launch system” that accelerates a small payload-carrying booster to hypersonic speeds with a spinning system on the ground. A chemical rocket would kick in once the payload has been launched from the ground system.

The image provided by SpinLaunch at the link appears to show a 3D-printed lifting-body type spacecraft attached to the arm of a large centrifuge. This suggests that after this spacecraft reaches orbit and deploys its payload, it would then return to Earth to be reused.

SpinLaunch has raised $40 million in investment capital, so they are real. Whether they can make this happen by 2020 remains to be seen.

Ireland’s government releases its space strategy goals through 2025

9:01 am

The new colonial movement: Ireland today released a national space strategy designed to encourage the growth of a commercial space sector by 2025.

You can download the actual report here [pdf].

They want to increase both public and private investment by 50% by 2025. Whether that means investment in private companies or simply a growth in a government bureaucracy is uncertain, based on my reading of the report. It appears their goal is to grow the private sector, but they will be using European Space Agency approaches for doing so, which tend to favor government growth and control rather than developing an independent commercial industry.

Sri Lanka’s first satellite launched from ISS

8:44 am

The new colonial movement: Built by two Sri Lanka engineers, astronauts this week successfully deployed that country’s first satellite into orbit from ISS.

The satellite was designed and developed by two Sri Lankan engineers – Tharindu Dayaratne and Dulani Chamika – studying space engineering at Japan”s Kyushu Institute of Technology.

Raavana-1 was deployed to the 400-km of orbit at an inclination of 51.6 degrees using the JAXA (Japanese Aerospace and Exploration Agency) owned Kibo experiment module, the paper said.

…Raavana-1 is expected to fulfil five missions including the capturing of pictures of Sri Lanka and surrounding regions, active attitude stabilization which ensures that satellite’s attitude is stable under the influence of external talks. It will have a minimum lifespan of one and a half years but was expected to be active for up to five years.

More significant than its Sri Lankan roots is that this cubesat was built entirely by only two engineering students. While it is apparently a simple engineering test satellite, that it could be put together so easily by only two people illustrates the revolution that the satellite industry is presently undergoing. Very soon it will literally be true that major satellites will be assembled in someone’s garage.

Boeing shifts space headquarters from DC area to Florida

8:38 am

Capitalism in space: Boeing today announced that it is moving the headquarters for its space operations from Arlington, Virginia, to Titusville, Florida, just outside Cape Canaveral.

From an operations point of view this move makes sense. The timing of this announcement suggests to me that they are trying to put a PR band-aid over yesterday’s damning GAO report about the endless cost overruns and schedule delays of their SLS rocket.

New Oberlin College PR campaign blames jury while declaring itself a victim

9:40 pm

This is how you get more Trump: Oberlin College has begun the rollout of a new PR campaign that tries to spin the recent slander decision against it as an attack on free spech while declaring the university a victim.

The email letter from Oberlin announcing this campaign, as well as the accompanying FAQ, are so filled with sanctimonious self-righteous blather and hatred for those it considers the great unwashed (such as the jury) that it is difficult to read. Go to the link and absorb it for yourself. It will disgust you, and reveal that the university, like Evergreen State College, has learned nothing from this episode. They are still certain they are right, and everyone else is wrong. They also think they are the only ones capable of understanding these issues, and that anyone who disagrees with them must be either a fool or plain stupid.

As noted at the link,

What Oberlin College wants to do is now (in addition to winning an appeal) is not to become the next Mizzou or Evergreen State, where unsavory social justice warfare by faculty and staff, egging on students, cause enrollments to collapse. Oberlin College, already suffering from weak enrollment numbers, faces that real possibility. [emphasis mine]

I think this is an understatement. I expect their enrollment numbers to drop like a rock. And if I had a child attending this college now I would pull them out as fast as possible, demanding my money back. Every administrator there should be out of a job. They are not qualified to run a college. In fact, I’m not sure they are qualified to do anything better than street sweeping, and in saying this I must apologize to every street sweeper in the world.

U.S. Communist Party praises Democrats’ policy shifts

9:22 pm

I wonder why? In preparation of its 100th anniversary, the U.S. Communist Party is heaping praise on the leftist policy shifts of the Democrat Party.

“There’s some thinking that ‘communism’ has always been a sort of bogeyman, and yet we want some of the same things,” said Harvey Klehr, a history professor at Emory College who specializes in the American left.

The connections between the Communists and the increasingly active Democratic left wing have been highlighted by Ms. Ocasio-Cortez and Sen. Bernard Sanders, who emerged from the democratic socialist movement to become leading critics of capitalism and guiding lights of the broader Democratic Party.

That, Mr. Klehr said, is heady stuff for the Communists. “The left is very excited that Sanders has normalized socialism, and in a sense he’s doing what they wanted to do,” he said. “So now I imagine those in the CPUSA think they’re not members of the Democratic Party but they want to take it over.”

Professor Klehr sees only a “bogeyman” when he talks of communism. What I see is an ideology that killed in the past century upwards of a 100 million people, and that’s not including the Nazis, which also followed a leftist socialist agenda.

But what matters that? This time Bernie Sanders and Congresswoman Ocrasio-Cortez will get it right. They are so much wiser than us!

Mass wasting on Mars

3:34 pm

Mass wasting in Martian crater
Click to see full image.

Cool image time! Mass wasting is a term that geologists use to describe a specific kind of avalanche, where the material moves down slope suddenly in a single mass.

The image on the right, taken from the image archive of the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced in resolution to post here, shows a dramatic example of this kind of avalanche. You can see two separate avalanches, each of which moved a significant blob of material down slope into the center of the crater floor.

Studying such events is important. Scientists know that Mars has an underground ice table at high latitudes. What they don’t know is how far south that ice table extends. This crater is located at 5 degrees north latitude, almost at the equator, so if this avalanche exposed any ice in newly exposed cliff wall that would be a significant discovery.

Based on the color image, there does not appear to be any obvious ice layers, as seen in higher latitude scarps in the southern hemisphere. This doesn’t prove they aren’t there, merely that this image was unable to see them. Maybe the resolution is not good enough. Maybe the ice is too well mixed in with the dust and dirt and it therefore isn’t visible. Maybe the ice table is deeper underground than the deepest part of this crater.

Or it could be that at the Martian equator the underground ice is mostly gone. For future colonists, knowing this fact will influence where they put those first colonies. Near the equator has some advantages, but if there is little easily accessible water those advantages mostly vanish.

At the moment we simply do not know, though much of the imagery now being taken from orbit are attempts to answer this question.

One final detail about the image. Note the slope streaks coming down the crater’s slopes. These remain their own Martian mystery.

SpaceX reschedules manned Dragon demo flight to November

2:46 pm

Capitalism in space: SpaceX has now apparently rescheduled its first manned Dragon demo flight to ISS to no earlier than November 1, 2019.

The information comes from a SpaceX application with the FCC, listing the launch window as sometime between November 1, 2019 and April 30, 2020.

This now gives us the time frame when both NASA and SpaceX expect to complete their investigation into the Dragon test explosion in March as well as institute changes as a result. It also suggests they now have a much better idea what happened and what they need to do, thus allowing them to create this time frame.
