What are 4 ways in which people can directly explore space?
Just by looking around themselves. The Earth is in space too, it's not a separate place. Current technology lets us build primitive rockets, and our ion engines are gutless too. Until a better form of propulsion than fireworks is invented then we're going nowhere. Some sort of shields will be necessary too, at the sort of speeds needed to cross interstellar space even hitting a particle of dust could be disastrous.
What are 5 ways in which people can study space without physically going there?
An orbiter and a satellite would be the same thing (although usually satellites refer to orbiters orbiting the Earth and orbiters to spacecraft orbiting other planets). They both could be considered probes, however not all probes would be orbiters. A rover and lander are practically the same thing, but the fact that one moves and the other doesn't might be enough difference. Telescopes would be another device that could be used to study space. Telescopes can receive visual data. Other types of telescopes can receive radio waves. Technically, visual light is just a portion of a larger electromagnetic spectrum, but there's still a bigger difference between a visual telescope and a radio telescope than between an orbiter and a satellite.
Should money be spent on space exploration?
Absolutely. Space exploration and satellites produce many thousands of jobs in our economy, and it's not like we're throwing that money into the Sun. It's all being spent right here, stimulating our economy and funding scientists, engineers, teachers, students, computer scientists, contractors, technicians, skilled laborers, and many more. Not to mention the scientific benefits and potentially huge discoveries - like the possibility of alien life.
What are two examples of exploring space and exploring the ocean depths are similar?
(1) Pressure problems (on different ends of the scale) (2) Far too cold in both places (3) No breathable oxygen (4) Both have issues with visible light, depending on where you are on a planet or moon (5) It's expensive to build anything to explore both places, and both places are huge, so you can only study tiny pieces of them at a time.
Why should we explore space when there are problems to fix here on Earth?
Simple. Let me explain with a ‘parable’ :Suppose you have a broken arm and fall off the top of the Empire State building. On the way down you have two options - fix yourself a plaster cast or strap on a parachute. You’d be silly to fix the cast.So it is with the earth. Out there in space are comets and asteroids headed our way. perhaps like the 7 mile wide one that killed the dinosaurs, perhaps bigger. So far our species has been lucky in that they’ve all missed but that’s NOT going to continue. Since we probably won’t see them coming in time, we can’t rely on Bruce Willis to go out and destroy them.Unless we start an international major space program our species and a good many others are doomed. It’s simply a matter of time.Who knows—it may be that space exploration may be a lot more profitable than war. While we are doing that we can afford to spend some of our time fixing the other world problems. It’s not an ‘either or’ situation we MUST do both with priority being given to space.
Do you believe humans would still want to explore space if dangerous aliens existed?
Okay. What a wild thesis! It ignores the crucial factor of where these posited aliens exist.Space is big! There could be dozens of alien races in our galaxy alone while we spend centuries exploring and never encounter them. Of course, the chances of even one spacefaring alien race existing in our galaxy are vanishingly small.Imagine, if you will, a blue ball filled with gold somewhere in Antarctica. What are the chances that you can find it with no clues? They are much better than the chances of encountering an alien civilization.I presume that most humans already make this assumption for several reasons, one of which is that they see too many sci-fi movies. Yet, a significant fraction of people still desires space exploration. It’s our nature.The only “dangerous aliens” we are likely to find are bacteria (and ourselves). Even that won’t stop us.
SHOULD USA STOP FUNDING NASA and SPACE exploration?
Satalites have helped make the society we have today possible: 1. We broadcast live around the world. 2. We spy with satalites and I would hate to see space war technology develope elsewhere but not in USA. 3. We can study the earth in space in ways we can't on the ground, (a birds eye view so to speak.) 4. Things with which others can explain. NASA and Space exploration may be able to detect an asteroid or comet that may strike the earth. Something most certainly did in Siberia in 1908. I would not go by any event that happened 65 million years age, but 1908 isn't so long age. We were so lucky then. If something like that happens over New York, 10 million people will be killed. If it happens over the ocean, the title wave will probably compare to the one in 2004. Colonizing space, the moon and/or Mars may prove to be invaluable in the future. It is proving difficult to clean up this Earth after we messed it up so bad. We could start over. (if you care about future generations.) We are a species that need to test it's limits. That is why Stonehedge and the pyramids were built. We need self esteem as a species. We will concider our selves disapointments if we don't do that which we are capbable.
Why did humans decide to explore Space? What were the events that led to Sputnik 1?
These are two different questions.Why did humans decide to explore space? Well, because it was there. And it was full of mysteries. And in many ways, it controlled our lives. So we always wanted to know more about it, from the day we gazed upon it. We were only limited by our technical know-how. We still are.What were the events that led to Sputnik 1? Fight for superiority. Both USSR (now Russia) and The United States, were hell bent on proving their military prowess during the Cold War. Both of them had considerable military presence on land, on in water, and in the air. The only thing remaining was the space. The first to reach there would have proved that their military prowess was greater than the other. That's the reason Sputnik 1 happened. That's the reason Yuri Gagarin went to space. That's the reason Apollo missions happened.
