You don’t want me to answer this question. You are looking for a great, positive answer that will make the future look bright not only for colonies on these places, but an economic base for those colonies.
Meanwhile, I’m going to say I don’t think there’s much justification even for people walking on Mars when our robots can do it more safely and less expensively and achieve the same or better results…. what to speak of “colonies.” I think it’s almost laughable and mostly just science fiction dreaming.
People may or may not one day walk on Mars at great risk, and some will probably die in the attempt. There is little reason to go there from a scientific point of view other than to say we did, just like we walked on the moon and then went away.
In the meantime, a safer, cheaper way is send our machines to go.
You see, what this is all about is finding life. What scientists want to do is prove that life can evolve elsewhere than Earth – a so far unproven theory. We want there to be life elsewhere because we want to prove that life was not “created” on Earth alone, but life naturally develops from matter when conditions are ideal.
We don’t need “colonies” or economic bases in space to prove that. We just need to find some germs under some rocks or on some moon around some planet in our solar system. For that we just need space vehicles and robots like the Mars Rovers.
Whether we find life or not is anyone’s guess, but it is still science fiction thinking we will colonize anything off planet.
Well, in my opinion we should focus on the Moon.
As for Mars vs. Venus, both have unbreathable atmospheres. Mars is very cold, hundreds of degrees below zero cold. Venus is hot, melt stuff in a few minutes hot.
Mars doesn’t have rain or surface liquid water.
Venus also doesn’t have liquid water on the surface, but it does rain. The problem is it’s raining sulfuric acid.
Any probes we’ve tried sending to Venus have become dysfunctional within minutes.
It is already more polluted. It has so much CO2 that it is uninhabitable. The atmosphere is too thin to breath and the solar rays from the sun are deadly.
If you count all the little nuts, bolts, loose wrenches and pieces of demolished satellites as satellites, then there’s a whole lot of junk floating around Earth. Thousands of pieces that pose a hazard.
Around the moon we have about three functioning spacecraft but have launched far more than that that have, over time, gone dead – perhaps crashed to the surface of the moon. Then we have the odd Juno spacecraft around Jupiter, the voyagers I and II and so on. We’ve put more space junk up there then anything else. This is a fairly accurate artist’s rendition of space junk around Earth.
The Russians have put several probes on Venus, the Americans and Europeans put a probe on Titan, we have probes on Mars, we flew a probe by Pluto and orbited Saturn for a long while before crashing deliberately. We presently have, as mentioned, the Juno spacecraft around Jupiter. We have hundreds of functioning satellites in orbit around Earth.
NASA never said anything like that. What did happen was that when the Apollo program was shut down, the building that the Apollo’s were built in was retooled for newer technology. In the process, some parts were thrown away because they were outdated and better stuff was available.
The reason we stopped going to the moon, at the time, was the Vietnam War. Congress needed to cut NASA’s budget to finance the war. After the near disaster of Apollo 13 and waning public interest, the money wasn’t there for continuing along that line.
Times have changed. The moon is a target once again. In the meantime, we have placed quite a few satellites in orbit around the moon. Due to problems with gravity variances on the moon, most of them have fallen from orbit and crashed on the moon’s surface or have become dead because of loss of power. However, there are at least three satellites right now that are active and in orbit around the moon. They are the Lunar Reconnaissance Orbiter (LRO), as well as the two ARTEMIS probes, which are functioning.
So not only did NASA not lose the technology, but we’ve been sending stuff to the moon for awhile. It’s just that we haven’t sent people in awhile.
We spend 600 billion dollars every year on the military. What would happen if NASA had that kind of money? Here’s a very cool YouTube video that I love to watch!
NASA and other space agencies have launched missions to the moon, just not with astronauts. For example, the Japanese space agency once launched a satellite to completely map the surface of the moon in high definition detail.
The main reason (not sure why you don’t know this) we stopped sending men to the moon was that the Vietnam war was getting expensive and politicians decided to cut the space budget because we needed money.
Seems now like NASA is revising it’s scheme to return to the Moon within a few years time. Surely you’ve been following the news.
