Orbiter Re-entry Path

We ran the CFD from Mach 0 – 25 and altitudes 0 – 105 km and plan to do ascent and reentry optimization next.  We are planning no greater than 20 degrees to stay stable.

Meshmixer loads the STL with colors and is a tiny installation compared to Blender. Blender only shows the colors on the PLY import, which is an even bigger file than the STL with colors embedded.

We uploaded the PLY file and added it to the ‘Files’ page with HTTP instruction to download rather than open the file.

With a simple switch in Blender you can display STL in color but it doesnt understand Vertex Color when loading STL so we use a PLY file for that.

Micro Climate Crater on Mars

According to our calculations Martian Scale Height of 11.1km means that we are only 30km away from reaching 0.7 bars of air pressure from the Northern Basin or Hellas Planitia. Can we deflect a comet or more to the same spot on such an elevation on Mars to excavate 30km? Then the water from the comet can produce a liquid water lake for us since it will be within the Armstrong Limit now and we can introduce algae and plant life in cheap greenhouses to slowly terraform Mars as a micro climate via photosynthesis to convert the CO2 to O2 slowly. The comet the size of Hailey’s would also contribute 1% to the Martian atmosphere with gas. While negilgible on it’s own if this becomes a regular occurance, 100 comet strikes will double the Martian atmospheric pressure and air density. This also means the future Micro Climate Craters can gradually be shallower and shallower eventually only needing to be 15km deep in the future.

Could we deflect enough comets to excavate 30km from the Northern Basin where it’s-7km from the datum? Or maybe Hellas Planitia. We could settle at the bottom of such a cavity and use airships for transportation without risk of explosion in the CO2 atmosphere, we could also live without the need of airlocks at our doors to maintain an air pressure bubble within the Armstrong Limit and we will have supply of drinking soda water and water for rocket fuel via electrolysis producing both breathable oxygen gas as well as hydrogen for rocket fuel and airships. We wont need full pressure space suits just flimsy stratapause type ones.
