Transport from Earth to Mars
Mars missions require the transport of equipment, material and people from Earth to Mars, and possibly back to Earth. This page wants to clarify the needed transportation volume and the proposed technology.
Preparatory Explorations
Some explorations are needed prior to the actual start of the colonization. Mostly, this will be probes to collect data, radio-transmitted to Earth. Some may, however, need to bring material from Mars to Earth for deeper analysis.
Initial Settlement Equipment
An initial settlement requires very much equipment. Shipping can be done
- with a series of space vehicles launched from Earth or
- with a big vessel assembled in Earth's orbit.
People
For colonization of Mars the colonists are traveling only one way. The journey takes at least about 10 months. During the journey the astronauts are subject to radiation, which requires means to protect them. People need to eat and drink during the journey. With currently known technology only a few persons can be brought to Mars with a single ship.
Open Issues
- How many tonnes can be brought to Mars with currently known technology?
- What is the mass and size of the above-named cargo?
