it would take at least 197.456 hours to get to mars from earth
No, we currently cannot. Humans cannot permanently live on Mars with current technology because the atmosphere of Mars is very thin, and it is made up of mostly carbon dioxide. Also, Mars can have nice 70-degree days, but many times it is below freezing.
As usual, that depends how fast you go. In general, you can divide distance by speed. However, in this case it is a bit more complicated; with current technology, the spacecraft won't go in a straight line. Rather, it will use the speed of Earth, and speed up a bit more, to go into an elliptical orbit around the Sun, which touches both Earth's and Mars's orbits. Half of such an orbit takes about 9 months. Of course, it is possible that in the future, improvements to rocket technology - perhaps better ion drives - manage to go in a more direct route, and to get there faster.
There are new space suits needed, because on Mars you have very big sand storms.
Current answer - Zero
Not with present day technology.
Using current technology: it can take as little as 6 months and as long as a year to get to mars at optimum position
Not with current technology. From launch to landing it takes probe a few months to get to Mars.
Yes, although modifying or "terraforming" it would take about a thousand years with current technology.
Mars, given current technology
It is possible to give Mars a breathable atmosphere and make it able to support plants and animals within a thousand years with current technology.
Our current level of technology does not provide a suitable, long term functional plan for any form of colony on Mars (At our current technology level)
We're not entirely certain that it is possible (at least with current technology) so any answer would be pure speculation.
With current technology, it would take around a thousand years to terraform Mars. So obviously, technology will have to develop quite a bit before it is seriously considered. That will be (most likely) centuries away. The reasons for doing it would be to provide another place for people to live in order to avoid overcrowding the earth. If it can be done on Mars, it would mean that we would be able to do it on the planets of other solar systems and would have an endless supply of planets to settle.
Today's current cell phones will not work on Mars. And we would need a way to get to Mars first.
As yourself. Probably not because mars is so cold and hot at the same time. ROvers could go Another Answer: It's not possible to "fly" to Mars. It is on the other hand possible for us with current technology to navigate interplanetary spacecraft to Mars.
Humans cannot permanently live Mars with current technology because the atmosphere of Mars is very thin, and it is made up of mostly carbon dioxide. Also, Mars can have nice 70-degree days, but many times it is below freezing.
it would take apporximately 4.2 seconds, jduging the wind speed in space, if light speed technology did exist.
