Map of shallow subsurface water in Valles Marineris on Mars

On December 15 scientists from Space Research Institute of the Russian Academy of Sciences in Moscow, Russia revealed a discovery of an area with an unusually large amount of hydrogen in the Valles Marineris canyon system on Mars. Assuming the hydrogen is bound into water molecules, as much as 40% of the near-surface material in Candor Chaos region appears to be water. The discovery was made by neutron detector FREND on ESA&Roscosmos's ExoMars Trace Gas Orbiter orbiting Mars since October 2016. FREND is mapping the distribution of hydrogen in the uppermost meter of the planet’s surface. Hydrogen indicates the presence of water, being one of the constituents of the water molecule; it can also indicate water absorbed into the surface, or minerals that were formed in the presence of water.

While water is known to exist on Mars, most is found in the planet’s cold polar regions as ice. Typically water ice is not found exposed at the surface near the equator, as temperatures there are not cold enough for exposed water ice to be stable. Minerals seen in this part of Mars typically contain only a few percent water, much less than is evidenced by these new observations. “We found a central part of Valles Marineris to be packed full of water – far more water than we expected. This is very much like Earth’s permafrost regions, where water ice permanently persists under dry soil because of the constant low temperatures,” told one of the scientists involved in the study.

These are very inspiring discoveries for the future human colonization of Valles Marineris region we have imagined in our speculative Mars Colonization Timeline!

⇧ In the area C up to 40% of the near-surface material appears to be composed of water (by weight).

The most water-rich area in Valles Marineris region is located in Candor Chaos:

Lunar colony in season 5 of The Expanse

After the bombardment of Earth Lovell City on Luna (the Moon) became the de facto capital of United Nations, one of the three competing powers in universe of The Expanse TV series - a political sci-fi drama set a few centuries in the future where humans have colonized the entire Solar system. Luna functions as a way station between Earth and the rest of the Solar system, and its spaceport at Lovell City serves as a natural meeting place between residents of the inner planets and Belters. Due to its lower gravity, Luna is the only body in the inner system that Belters can easily visit. UN citizens living on Luna are generally wealthier than most of their counterparts on Earth.

As Mars was one of the major locations in season 4 of the show, Luna is in season 5, coming into spotlight after the bombardment of Earth. Here is a collection with HD images from the Lunar scenes in season 5 of The Expanse. There are a few more from the trailer of the season.

SpaceX Legacy: episode 1: Manned Mission to Mars

YouTuber iamVisual has started to produce animated short series about the legacy of SpaceX – the leading NewSpace company developing innovative and cost-effective rocket and space technologies, including the first fully and rapidly reusable rocket system – two-stage super heavy-lift Starship rocket. The 1st episode of the series visualizes first human mission to Mars. You can watch it here:
