moon to mars!!?

Question

hey guys.......... i really need ur help..........i hav 2 prepare a demo or anything for my inter school exhibition on the topic ' SPACE JOURNEY- MOON TO MARS'................can any1 plz suggest me any project or even an idea will do............. i seriously need it!!

Answer 1

Here are a few ideas:

The Surface gravity on the Moon is only 1/6 the surface gravity on Earth. It is easier to escape the Moon than Earth.

Escape velocity on Moon = 2.4 km/s
on Earth = 11.2 km/s

Because there is no atmosphere on the Moon, it may be possible to build an "external" propulsion system. For example, a linear accelerator (maglev type) where the space vehicle is accelerated to escape speed on a track: the magnetic motor is part of the track system (does not have to be launched in space), it accelerates the vehicle to escape speed and lets it go. No air to slow down (or burn up) the vehicle on its way up and away from the Moon.

Lots of materials available on the Moon (you may have to process it), so that you could built the launch track and the space vehicle from materials found on the Moon, instead of using large amounts of fuel to raise the materials (or the vehicles and its engine) away from Earth's greater gravity.

The environment of the Moon provides a better place to test the materials that will eventually be used in space and on Mars.

PS
The launcher can use rails (it is called a railgun) or coils (a coilgun).

PS #2: The cost of building the launcher can be amortized over other uses, such as sending refined metals (mined and refined on the Moon) back to Earth or, even better, to Earth orbits where orbitting Space-Shipyards are building the bigger ships of tomorrow (in Star Trek, the Enterprises were built in orbit)

Answer 2

Here is another idea. Point out that, although it is easier to get to Mars from the moon, until the infrastructure is on the moon to build and equip the rockets and space vehicles, it is much more efficient to go to Mars directly, bypassing the moon. To get the infrastructure going on the moon will take multiple landings of material to process ores found on the moon, and multiple landings to process the metals and nonmetals obtained into equipment.

And, in terms of change in velocity (from earth takeoff to earth landing) it is actually cheaper to go directly to mars, rather than via the moon, because mars has an atmosphere, which will greatly assist the braking necessary to approach and land on that planet. The moon has no such atmosphere to assist, and all the braking must be done by rocket power. The cost of going from the moon to mars will be cheaper than from the earth, however, once spacecraft can be built, fueled, and launched from the moon
