#Astronauts 👨‍🚀 travelling to #Mars would encounter #radiation ☢️ levels higher than humans have ever experienced, and be exposed to them for much longer.

To protect them, the #spacecraft would either have to be much bulkier, making launches expensive and difficult, or be made of more efficient #shielding 🛡️ materials. https://www.skyatnightmagazine.com/space-missions/how-will-humans-survive-the-journey-to-mars

Two years ago, NASA's Curiosity Mars rover captured this feathery iridescent cloud after sunset. The color is created by diffraction effects when sunlight is scattered by small CO2 particles in the cloud.

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.

Finally - Amazonis. The name makes us think of the Amazon in Brazil, but originally it was the name of a female warrior society whose tales crop up all over the place in classical contexts. Amazons fought on the side of Troy in the Trojan war and are usually associated with northern Turkey.

OK, enough names. Now we will return to our sequence of Mars maps. #maps #Mars

Amazonis Planitia on Mars is named after the Amazons, a female warrior society who fought in the Trojan War, on the side of Troy. They are associated with a lot of places in the region but especially with northern Turkey. The modern use of the name in Brazil is not connected with the ancient stories except that Spanish soldiers claimed to have encountered female warriors in the area.

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

Utopia on Mars is where Viking 2 landed in 1976. But it's not a real place and not a classical name - it was invented in 1516 by Thomas More and literally means 'nowhere'. It refers to a place so perfect it couldn't really exist.

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

A map of Mars drawn in 1957, just before the Space Age began, by Glauco de Mottoni y Palacios for use as a key to nomenclature. It shows subtle light and dark markings resembling those illustrated by Nathaniel Green (shown earlier in our sequence). No topography is visible.

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

A map of Mars made for NASA in 1962 (this is a later printing of it) by the US Air Force. The original has been stripped of text and transformed to an azimuthal projection.

No - Schiaparelli saw Mars like this - with south at the top. Until the dawn of the space age most planetary maps were drawn with south at the top as seen in an inverting astronomical telescope. Only when maps might be used for direct physical exploration did the convention change to avoid potential confusion. Rather than turn our screens upside down, let's do a 'rotate 180 degrees' in Photoshop. Simples! #maps #Mars #Hubble
