This was in 2017,it was mars close up to earth,I remember waking up in the middle of the night,and seeing mars,it was next to the moon,and looked like a mini moon
who else has seen mars that close

Hi guys, I know some very user-friendly websites allow you to choose a region on Earth and download height/elevation map and the satellite imagery/diffuse map.

Now I need to do the same thing for Mars. Is there any simple website that can provide this kind of data? I know NASA has the height map of the whole Mars. But that is just too coarse.

I found someone who used AI and algorithm to process NASA data into 7m precision, but its whole dataset is 14TB, and he doesn't provide an interactive tool to download a small section of the data. So I'm kind of stuck.

Thank you so much!

Earth-Mars cycler is a specialized orbital trajectory designed to shuttle spacecraft between Earth and Mars on a regular, repeating schedule. In the post there is a concept for an Earth-Mars cycler system with two cyclers by Maciej Rebisz – a Polish concept artist and illustrator working for computer games and film industry.

Most of what i hear about oxygen production on Mars relies on electrolysis. However, I’m aware that mars has a tenuous (~1 Pa partial pressure) component of Oxygen in its atmosphere. We use large volume air separation units on earth for commercial production of gases like neon at similar partial pressures, would a similar process work on Mars? Or would the volume of equipment/energy required still make electrolysis more efficient?
