Also, I don't get what you are griping over. In the first paragraph you appear to feel that instruments such as the Hubble space telescope is a waste of money, but in the second paragraph you change it to deep space exploration robots. Which one is it?
I never said anything about robots. Just to reintereate my point, "it just seems so pointless to divert precious monies into exploring parts of space we will never be able to reap any direct benefit from. Instead of working on moving out from our own planet in to the surrounding space and learning more and more about the solar system we live in and CAN reap direct benefits from."
Exploring implies robots. But anyway, I see now that you are talking about Hubble. Hubble doesn't go anywhere and plant a flag, it just hangs around and watches history unfold. It's job is that of a historian, not of an explorer. You might want to read up on the main objectives of the Hubble Space Telescope.
The Announcement of Opportunity for The Hubble Space Telescope, dated March 1977, cites that the main scientific objectives for Hubble are to determine:
A. The constitution, physical characteristics, and dynamics of celestial bodies.
B. The nature of processes which occur in the extreme physical conditions existing in and between astronomical objects.
C. The history and evolution of the universe.
D. Whether the laws of nature are universal in the space-time continuum.
As you can see, nowhere does it mention exploring. You may not feel these are important goals, but physicists and other scientists may find the information collected useful, since one day it may help us build bigger, faster space vehicles. On another note, you wanted to know how water got on Mars in a previous post. Well, some scientist spectate that water may have been brought along by comets that crashed into the red planet. And it was partly through images taken by Hubble that they know that some comets contain frozen water. So before you go assuming something like Hubble is useless, you should have read up on what we have learned from it first.
You are using current knowledge again. Columbus had no idea how long the trip was going to take, yet he decided to venture forward. Back then, it was a foolish decision to many sceptics, but now we praise his actions and wisdom.As far as columbus is concerned my argument is a distance and time thing. If we had the ability to travel to another solar system with in our lifespan then fine lets go for it. other wise lets get our selves established so we can develop the base line for doing this.
