#Space 🌌 is a far more logical, sensible place to do #fusion, because that’s where it wants to happen anyway. In 📆 2027, we’re going to send a small part of #Sunbird in #orbit. The first #functional Sunbird will be ready four to five years later. Sunbird could deliver #cargo to #Mars 🔴 in under six months https://edition.cnn.com/science/nuclear-powered-rocket-pulsar-space-spc/index.html

@clive And a former nazi rocket scientist Werner von Braun created: ”Elon, the Techno King of Mars” in his 1952 science fiction novel: ”Project Mars”

The society of Mars was run like that very same technocracy, with engineers running it while a CEO-like absolute dictator calls the actual shots.

Coincidence? I think not. Musk lists his registered title as ”Techno King” in the official papers of Tesla inc.

A picture of #Deimos in front of #Mars taken by #Hera yesterday - more pictures in https://www.esa.int/Space_Safety/Hera/Hera_asteroid_mission_spies_Mars_s_Deimos_moon
Martian moon Deimos appears dark, framed by the brighter planet Mars behind it, in this visible light monochromatic Asteroid Framing Camera image, acquired by ESA’s Hera spacecraft during its gravity-assist flyby on 12 March 2025. The car-sized planetary defence spacecraft was approximately 1000 km from the 12.4-km-diameter Deimos moon when this image was acquired. Deimos orbits approximately 23 500 km from the surface of Mars and is tidally locked, so that this side of the dark moon is rarely seen. At the top of the image is the bright Terra Sabaea region, close to the martian equator, outlined by darker regions about it, with part of the 450 km-diameter Huygen crater seen to the right side of the image. To the bottom right corner is part of Hellas Basin, among the largest known impact craters in the Solar System with a diameter of 2300 km and a depth of more than 7 km. Hera’s 1020x1020 pixel Asteroid Framing Camera is employed for both navigation and scientific investigation.

Not to spoil the novel's plot, but Nazis where on the #Moon way earlier than Nazi Musk was even a molecule in this world, according to #Heinlein. They didn't fare well there, either.

So, Musk & Co are now trying a #Mars grift…

The Perseverance rover captured some pretty massive dust devils earlier today. That large one in the foreground was at least 300m high.
EDIT: corrected height estimate from 500 to 300m.

20 frame animation showing a mostly flat terrain on Mars with a couple craters and a few hills towards the horizon. Three dust devils can be seen, a large one in the foreground is moving in an lefthand arc and shows significant rotation. It also casts a shadow onto the ground.

Next, Utopia, where Viking 2 landed in 1976. Unlike all those other names, this is not ancient and comes from Thomas More's book of 1516. It literally means 'nowhere' and is used for a perfect place or society (maybe so perfect it couldn't really exist). In the book it was an island out in the Atlantic near the Americas.This name is not on Schiaparelli's map and probably comes from Flammarion and Antoniadi's map of 1900. #maps#Mars

After that rather long excursus into Martian nomenclature we return to the sequence of Mars maps. Looking back, we saw maps of light and dark markings, at first barely glimpsed through telescopes, but evolving into quite sophisticated drawings - Green's map is quite realistic though others seem more sketchy. Schiaparelli saw lines ('canali') and Proctor rendered them as rivers. From 1890 to about 1930 many maps showed canals, which we now discount. #maps#Mars

In the middle of the 20th Century canals had fallen into disfavour. Typical maps of the 1950s, such as the International Astronomical Union (IAU) map drawn by Glauco de Mottoni y Palacios in 1957 as a key to official nomenclature, showed broad light and dark areas similar to Green's map. Here it is stripped of names (by cloning) and transformed to my common projection. Nothing suggesting topography or geology is visible. Don't be fooled by assertions that some people saw craters. #maps#Mars

That last map was drawn in the year of Sputnik. Direct exploration by spacecraft was not far off, so NASA needed a new map. The job went to the US Army and Air Force, who both had large mapping agencies and were gearing up for Moon mapping. I will show the Air Force map. You can see it here:

https://www.lpi.usra.edu/resources/mars_maps/MEC-1/

Look at that - it has canals! So did the less aesthetically pleasing Army maps. It's a curious footnote of Mars mapping history. #maps#Mars

Here I add my manipulated version of it for easier comparison with the others. Look at the original - it's north up, not south up. The old astronomical convention was dropped. Longitudes go from 0 to 180 east and west from the prime meridian (still using the 1840 version of zero longitude). Our familiar names are on display. Compare Syrtis Major's longitude here and on the previous map - this one is 10 degrees too far east. Oops! #maps#Mars
