Canadian miniseries : Race to Mars

[jamahir]

Hello, linked below is a two-part miniseries called Race to Mars. It is a Canadian production and quite realistic. The race refers to one bunch of countries in race with China for a manned landing on Mars :

Part 1

Part2

Worth a watch.

Will watch later.

Landing on Mars is easy. Getting back is the tough part. Put it this way..we have brought back about 500lbs of moon rock but haven’t even brought back a tiny ounce from Mars...never mind a person.

Only SpaceX has the tech to do this.

Put it this way..we have brought back about 500lbs or moon rock but haven’t even brought back a tiny ounce from Mars...never mind a person.

I suppose that is because, unlike Moon, Martian gravity is not that much less than of Earth and therefore needs a proper infrastructure to lift-off back from Mars to Mars orbit.

Canada is too cold. Can't do anything. America has a small chance. Best bet is China.

Seen it years ago. Nice series.

how the bodies will react to low gravity and high solar radiation is what interests me
Will the first blokes on mars live their last years in varying stages of cancer?

Still haven’t watched the movies but...

You basically need almost a SaturnV sized rocket on Mars to blast you off the surface and get you up to a speed fast enough to break Mars gravity and fling you back to Earth. Not an easy thing to do.

Since that isn’t practical. You’d need one rocket to get you off the surface and into orbit and another rocket already in orbit that could get you back to earth.

Now you have to figure out how to get that second rocket parked in orbit. That’s actually the most tricky part. You need a rocket that could fly to Mars, slow down enough to enter orbit, then have enough fuel to speed up and leave orbit. Wow what a mess! The reality is they probably would have to send this ship months in advance...possibly even more than a year. It would travel to Mars as slow as possible to reduce the amount of fuel expended to get there and slow down maximizing the fuel available for the return trip.

To solve this SpaceX StartShip comes in two pieces. The crew capsule is designed to have enough power to get into orbit by itself. This will only be used during the Mars liftoff. When on Earth the bottom booster will be used to get it into orbit conserving it’s fuel.

Now the tricky part is sending a fuel ship to Mars. That’s a lot of fuel to be lifted into orbit. It may take several trips up to refill a fuel ship with that much fuel.

Basically nobody else even has a valid plan.

NASA has an on-going ( on-going I think ) competition for companies / groups to create 3D-printed Mars habitats using local materials ( ISRU - In-situ Resource Utilization ).

I haven't read the below articles but am sharing them because of a yahoo.com article that spoke about one of these competition entries :

https://www.nasa.gov/feature/langle...ey-s-icy-concept-for-living-on-the-red-planet

https://www.nasa.gov/directorates/spacetech/centennial_challenges/3DPHab/top-10-virtual-model-stage

All these entries will have to demonstrate protection - at least in design I believe - from radiation, sand storms and meteorites.

Radioactive material in nuclear power plants are under water to shield people from radiation. I believe you’d need meter thick walls of it to block it in space. You could simply have the drinking water and fuel tanks designed in a manner to provide shielding.

Yes, that is the practical thing to do while transiting in space, and I wonder how much water will be needed for a colony crew of 50 people.

And if we were to talk about Mars habitats, maybe most of the structure should be underground to give it additional anti-radiation and anti-meteorite shielding ( other than a layer of water ).

The entries in the NASA competition all seem to be surface habitats. But I must say here that I haven't read the links I posted previously, so there may be underground habitat designs too.

To solve this SpaceX StartShip comes in two pieces. The crew capsule is designed to have enough power to get into orbit by itself. This will only be used during the Mars liftoff. When on Earth the bottom booster will be used to get it into orbit conserving it’s fuel.

So, for the StarShip to land safely on Mars, will a landing pad be constructed by robotic machines ??
