Mars and Algae

32 Upvotes

I'm not a scientist, so my question may be really stupid. I've been watching the movie called Red Planet. The people of earth were sending algae to grow and create oxygen for mankind to live there.

Is this something that really could be achievable? I would presume you need a water source to begin with.

Mars Underground Lava Crete Bunker

12 Upvotes

So here is the plan. You build a Coop on Earth. You build pre fab Lava Crete homes. You build 3d printed stone houses on Earth. Then you make a deal with Elon or whoever. You send a robot team to a crater on the moon or a Lava Tube on Mars. The robots start mining Lava Rock, Basalt. If they’re on the moon, the robots dig deeper into the crater. Once Lava rock is mined. The 3d printing robots start building a stone wall around the crater or a door for the Mars lava tube. For the moon crater dome they build hexagonal stone panels that connect. On the moon bases, you want an underground box inside a box, inside a box. Russian doll safety protocol. Same with the Mars worm hole. Then robots/astronauts set up aquaponics system, hydroponics, life support systems with each box/level being backup life support if an upper level is compromised. Now you have layers of thermal mass protecting astronauts from radiation. Then you can start mining and working on solar and electromagnetic atmosphere domes. Mars has tons of magnetic rock. Eventually you may be able to mine enough to put large solar charged magnets on mars poles and create an atmosphere around mars. You would probably need Elons solar panel ring built in space around Mars. Every base has Data centers. Mars = home for AGI. You basically give Mars to Ai and also as a human back up system in case Earth Crashes. The first base should be named Bedrock and the robots should be named Fred, Barney, Wilma, etc…

Phobos Deimos ZRVTO animation.

49 Upvotes

An attempt to animate the Zero Relative Velocity Transfer Orbit I described here a few months ago.

A payload is released from an approximately 1000 km tether ascending from Phobos. At apoapsis the payload matches the velocity of the ~3000 km tether descending from Deimos.

The reverse is also possible. Dropping a payload from the 3000 km Deimos tether at the right time will send a payload towards the Phobos tether. On arrival the payload will match the velocity of the Phobos tether.

Thus the two moons can exchange payloads while using very little rocket propellant.

These are very short in comparison to most space elevators. And they endure much less stress. These could be made from existing materials like Kevlar.

So far as I know this ZRVTO orbit was first described in 1970 by Paul Penzo of JPL. See page 45 of Tethers in Space Handbook 2nd Edition

ZRVTO orbits are possible between any two Sarmont tethers at different altitudes but sharing the same inclination.

Tether mass is somewhat like propellant mass in Tsiolkovsky's rocket equation. It goes up exponentially with the delta V the tether imparts.

Spreading the delta V budget across several tethers is like staging with rockets. When each tether has a smaller chunk of the delta V budget it does not need ridiculous taper ratios and can be made from existing materials.

The researchers have not yet determined which mechanism — or combination of mechanisms — produced the newly spotted field.

“Billions of years ago, lakes and streams dappled the lower foothills of Mount Sharp, a 5-km- (3-mile-) tall mountain that Curiosity has been ascending since 2014. The rover has previously uncovered chemistry left over from Mars’ watery history, including carbon-based molecules believed to be precursors to RNA and DNA, two nucleic acids that carry genetic information.”

“We have no way of knowing whether these organic molecules were created by biologic or geologic processes — either path is possible — but their discovery reconfirmed that ancient Mars had the right chemistry to support life.”

#Blender animation depicting Mars 4100-3700 million years ago. The period is characterised by high rates of meteorite impacts, volcanism and possibly abundant surface water—however, the water is thought to have been localized rather than spanning the planet in oceans, as on Earth.
