The Mars:

1.Dense, Rocky composition

2.Core-Fe, Ni, Su -this provided magnetic field during the early years-this protected mars from solar dust.

3.Mantle-silicon minerals-rocky

4.Crust -iron minerals-reacts with traces of oxygen and forms rust soil useful to grow crops like flax, hemp, and bamboo.

5.soil- alkaline,na,mg,cl,k

6.perchlorates and found on the surface of mars.

7.The mars today-dry desolate and cold (earlier it was much warmer, water was known to exist)

8.Water still exists but in form of polar ice caps. Polar ice caps are covered with dry ice

9.Can barely stand on mars due to:

•radiations

•low temperature-average temp may range from -220 F to 70 F

•the temperature may fall up to -225 F

•low oxygen

•low atmospheric pressure

•strong winds may take some months to settle down

•The time needed for sun rays to fall on mars-12.6 min

on earth=8.3 min

•gravity on mars:3.721m/s^2

earth:9.80m/s^2

•this damages the bones-calcium levels decrease

•distance of mars from the sun:228 million km

earth:151.2 million km

•10*mars weight=Earth weight

•the radius of mars=3389.5 km

•6*mars volume=earth volume

•100kg on earth=38 kg on mars

•2 satellites=phobos(nearer),Deimos

•1 day=24 hrs 36 days

•1 year=687 day

•atmospheric conditions

mars: 

96%c02 

1.9%argon

1.9%nitrogen

the small amount of oxygen

co

water vapor

methane

Earth:

78% nitrogen

21%oxygen

1%other

•rotation angle earth:23.5

mars:25.2

•seasons-spring summer autumn winter(2 times longer)

•7 months to go to mars

•co2+h20->o2+ch2(methane)->fuel generation

To construct a habitat we need to consider the following points:

•  temperature

•water availability

•material availability

•solar energy capture potential

the material which we are using should withstand:

•Martian winds

•Sand-dune build-up

•Thermal undulation

•Meteorite impact performance

the material used by previous international winners on the same project are:

•    Regolith: means astronauts have sand-like material on hand made of SO2+ironoxide+aluminum oxide and sodium oxide and trace materials

•We need to maximize the use of indigenous materials and resources.

like geopolymer concrete mixture called mars Crete mars creep consists of indigenous minerals including basalt rock which is used as aggregate

•  Kaolinite: It is used to obtain medical and is used as a binder and sodium and silicon compounds are used as agents to activate meta kaolin with water obtained from ice.

•engineered geopolymer concrete and borate glass: the composite material is lightweight thermally insulated resistant to chemicals freezing and fire as well as impermeable and protective against cosmic radiation. 

    Information on 3d printers:

Gantry system

Construction 3d printers-

Robotic arm

1)Gantry System-

In 3D printers, the gantry is the frame structure that supports the printer head along the X/Y axis as the printer head moves around to print the part on the build platform (similar to an arcade claw game). 3D printers typically use 3 gantries to support the printer head.

The gantries are moved by stepper motors, which use digital pulses to move and track the gantry. The stepper motors allow for high resolution movement by allowing the pulses to move the motor at a small fraction of a rotation. The gantries hold up the printer head as it moves along the build platform.

2)Robotic arm 3d printer-

They donot require support.

These printers increases the degree of design freedom.

Which is suitable for construction in mars?

Robotic arm would be preferrable.

Challenges to be noted when designing the printer(robotic arm)-

->How to gain structural strength?

->Regular 3D printing does rely somewhat on gravity to hold each layer together before they cool and dry. With less gravity how to help it all stick?

->The material with which the printer is designed.
