Human should start exploring beyond the orbit around earth
Human should really start exploring beyond their comfort zone, the orbit around earth. A good start would be going to the moon and back regularly, it would solve many of the technical space technoloy needed for further space travel. If human do not make this move soon, they will always be stuck with primitive space travel technology. If they cannot solve short space travel issue, they can forget about getting to mars and back. It is naive to think that they can actually leapfrog the technology needed in space travel. There is saying that says "learn to walk properly, before you attempt to run" ! Everyone know that space is a harsh environment, human are weak phyiscally and need all the basic elements to survive. So there are so many things they need to get right before further exploration can proceed. Get the basic reliable launch technology right for regular launch, at least launch within hours of a initial mission. Get the basic space craft to survive for 30 days, ...
