  1. Re:Must die? on NASA Debates How And When To Kill Hubble Telescope · · Score: 1

    We have plenty of other launch vehicles: Scout, Delta, Atlas, and Titan. Altas and Delta are capable of putting payloads into geosynch orbit (although Delta can only put something into a high eliptical orbit, so the payload must be able to take itself to true geosynch). All of our launch vehicles should be easily capable of reaching the Hubble.


    I think you misunderstand me. I'm not saying that there's any issue in reaching the Hubble. I'm saying that we don't currently have a craft capable of "nudging" the satellite out of orbit without turning it into so much scrap metal.

    If NASA isn't willing to spend the $600m to refurb the Hubble (most of this cost is the shuttle launch itself), their -only- deorbit option is an unmanned launch.

    As far as I'm aware, it's the Shuttle that's been servicing the Hubble. Given that the Hubble is incapable of changing its own orbit (who thought up that one?), wouldn't a stopover by the shuttle make sense? Even if they do use an unmanned vehicle, that's still vastly different than a vehicle capable of boosting the satellite out of orbit.

    In that case, it would take a shuttle mission to decommission the Hubble as it would lack the necessary hardware for a de-orbit burn.

    That would most likely be a no-go. You'd need an extremely sophisticated craft in order to match velocities and orbit, then begin a powerful enough burn to overcome the Earth's pull. The only powerful enough rockets we have today, are ballistic missiles for satellite launches. NASA did once conceive of an automated "space tugboat" to move satellites in and out of higher orbits. Unfortunately, it wasn't as economical as ballistic rockets and no one wanted to repair old satellites. As a result, the tugboat was never built.

    I seriously doubt that Hubble has enough reaction mass to send it out of orbit. In fact, the Hubble most likely uses some form of OMS (Orbital Maneuvering System) thrusters to change orbit. These thrusters are very weak and are good for adjusting your rotation or changing the ellipse of your orbit. Changing the path of an orbit can potentially send a craft into a downward spiral that would (eventually) result in atmospheric contact.

    Fair enough. I'm glad someone has been doing their homework around here. :-)

    As always, there are problems with any theory. A quick Google for "Canopy Theory" will in fact bring up many debates back and forth that this theory is not a valid one. Many will explain that they think the "Hydroplate theory" is far more feasible. Others will argue that the two theories could be combined to explain the amount of water plus longer life spans. Some will reply that the longer life spans could be explained by stronger magnetic forces alone. And yet others will state that the "Hydroplate theory" violates a few laws of physics.

    And what does this all come back to? My original statement that we don't really know yet where all the water came from, but theories do exist. These theories run into the same issues as any other scientific theory. (e.g. Where are the missing links? Why is the geologic column out of order in some areas? etc., etc., etc.) Geologists will debate on, and maybe one day we'll have a nearly irrefutable theory. Until then, we'll just have to keep watching the debates! :-)

    I'm not quite sure how you came to that conclusion. In order to "steam-broil" the ark, the water would have needed to maintain an extreme temperature *as it was falling*. Yet it couldn't fall if it was still up to temp.

    That's a bit like saying that ice can't form on a lake because it would fall the bottom and crush all the fish. As one of the odd inconsistencies in our universe, ice floats despite being more dense than water. In the same way, water allows dense air pockets (bubbles) underwater. In fact, if water didn't have all kinds of weird properties, our universe couldn't support life.

    My point is that you shouldn't be so sure about that. It wasn't until the 20th century that we caught up with the Romans and Greeks. Archimedes, for example, was far better at math than anyone prior to the 20th century. His revelations into geometry were the basis for modern geometry.

    > However you *did* say that evolution is a random theory.

    No, it's not a "random" theory. It's simply a theory that has evolved based on the original assumption that many animals are similar, therefore there must be a logical chain or "evolution" to the appearance of the species. That's a great theory, but until it can be proven, it's still a theory.

    I'm not stating that "POOF, everything appeared". I'm simply stating that the scientific community is teaching a lot of theories as "fact" even though it hasn't been proven. This is BAD science! And as I stated before, the Earth may very well be older than 6000 years. My only statement is that I believe that MAN plus the modern life we see today, has only been around for 6000 years.

    As for there being life before 6000 years ago, that is a possibility as well. Several Biblical scholars have been trying to puzzle together references to multiple worldwide floods. Their current conclusions state that there was a thriving Earth prior to our creation that was ruled by Lucifer. (The former Arch-Angel turned devil for those who know the Bible.) Thus we have "In the beginning God created the heavens and the earth". Then you have the time frame which is irrelevant to us (as we didn't exist), the destruction of the Earth by flood, then "And the Earth was without form and void. And God moved upon the face of the waters." You know the rest.

    > You see, that's the problem right there! Supporting an idea using unverifiable data.

    You're confusing statements I make based on belief vs, statements I make on science. I *believe* that we humans today have only been around for 6000 years. That brings up the questions of, "Who were the Neandrathals? Were they apes, diseased humans, or some other form of life? Are they the Nephillim the Bible speaks of? Or perhaps they were our predecessor species that was wiped out in the previous theory." These are questions that are being theorized on. The creationist's theories are no less valid than the evolutionist's theories. Neither has been proven, so there's still a lot of room for HONEST debate.

    > Substitute bible for internet in that statement, and it's the same.

    The really amusing part is that most people miss the purpose of the Bible. It is not a science book or a "how to on everything". It is simply a recording of Jesus's lineage. That is its sole purpose. God threw a lot of extra clues in there to help us out in a scientific fashion, but he certainly didn't try to explain Quantum Physics to us.

    How do you know that they believed the world was flat? The Bible certainly doesn't state it. The "flat" world model was an invention of the middle ages. Many things had to be rediscovered due to the impact that the fall of Rome had on science and philosophy. Before that, the Egyptians were building pyramids, the Greeks were figuring out how to use a lever on the earth, and the Romans were building aqueducts and computational devices.

    Perhaps the original Atlas image was a large flat surface on his back, but I've always seen it as a globe. Interestingly A quick google search for "was atlas holding a globe or a flat earth?" comes up with this Biblical opinion.

    Think "atomic power". Thus the tanks could be strapped onto a big engine and thrusted toward to moon. There would be no real craft. Plus, atomic power means that it could be redirected back to the waystation and used again. Have enough of these en route, and you can keep up a constant stream of hydrogen.

    No, cost is essential. If it costs less to deliver a larger load where only 80% of the original payload makes it, then we'll send hydrogen tanks that loose 20% of their hydrogen. Using a high speed chemical rocket is tremendously expensive.
