I also need to know about how long is the average time it takes to get from earth to mars in todays shuttle???
102722
Space Shuttle travels about 17,580 mph\n\nEarth to Mars is about 35,000,000 miles (at its closest) so...\n\nabout 1990 hours to get to mars, or around 82.95 days.\n\nHowever, as the previous answerer stated, fuel for that would be almost impossible to do at those speeds, but that wasn't your question, was it?\n\nAll of these numbers are approximates. Hope this helps.

if we travel at the speed of light, it would take approximately 4.2 years to travel to Proxima Centauri.  Obviuosly, we can't reach that speed.  Space Shuttles can reach a speed of 17,500 mph or 7823.2 m/s.  With this speed, it would take 161059.4 yrs

You are reffering to the Mars Exploration Rovers.  There is also a probe on it's way to Mars to see if it had any long standing bodies of water.

The first Mars Rover made the trip in eight months.\nIt's about fifty million miles away.\nI don't know how cold it is.
407005
I'd say 17000-19000 miles per hour.\n\nIts at a inclined geo-stationary orbit probably.

Look at how many sattelites we put up... there is something wrong with your reasoning, you're ignoring a lot of the facts.  How is it more difficult now?  A civilian recently built and flew his own spacecraft into space 3 times successfully.  Hundreds of satellites are orbiting the earth as we speak.  How does it seem space travel is more difficult?  We have several astronauts in a spacestation right now... Civilians have purchased tickets into space, the people on the space station have been relieve, replaced, etc multiple times... As far as the moon goes, there really isn't/wasn't any reason to go back, not a whole lot there if ya know what I mean ;)  They're working on mars projects continuously... just because a few landers and orbiters crash doesn't mean things are more difficult.  If you do some research you will find literally hundreds of crashes, mislaunches, explosions, and other quality errors; the old times make the number and degree of current mistakes seem almost trivial.  Science and technology have proven themselves time and time again when it comes to space, and it keeps getting better.

As above, the water, atmostpheric pressure, and temperature aren't concducive to human life. But there's another issue: response time. Right now, we have the technology to build a station on Mars. But if something went wrong, it would take us two or three years to get a repairman there!\n\nBecause it takes so long to get there, any settlement on Mars would have to be COMPLETELY self-sustaining, and that's what's really holding us up. (We couldn't even keep the International Space Station going as long as it should have).

What will it cost to get to Mars? Trillions of dollars if you really have to go today, and there's 80% that it will cost you your life too.\n\nWhat's the atmosphere? A thin layer of carbon dioxide.\n\nWhat's the weather? Unpredictable like earths, with multiple sandstorms.\n\nSize of mars? 6794 km in diameter

The Apollo missions that had to get to the moon had to hit 25,000 to get out of Earth orbit and for certain maneuvers around the moon. The space shuttle and/or ISS orbits the Earth at speeds between 17,000MPH and 18,000 MPH.\n\nUnmanned Spaceborn:\nHelios probes orbiting the sun hit 252,800 km/h in 1974.\n\nManned Airborn:\nOct. 3, 1967, the X-15A-2, piloted by Major William J. Pete' Knight, went Mach 6.7 (4,520 m.p.h.) above the Mojave Desert. Record stood until broken by the Space Shuttle in 1980. Highest altitude reached by X-15A was 354,200 ft.\n\nThe fastest air-breathing, manned vehicle, the SR-71, achieved slightly more than Mach 3 back in 1964. Chuck Yeager hit Mach 1 in 1947 with the X-1.\n\nUnmanned Airborn:\nRecently the unmanned speed record (in proximity to the earth anyway) was broken. The X43A hit Mach 9.6+. Scramjets are thought to be capable of hitting Mach 15+.\nexternal link\n\nManned Ground:\nMach 1.016 in the "ThrustSSC" by Andy Green in 1997.\nexternal link\n\nUnmanned Ground:\nA rocket sled hit Mach 8.5 (unmanned)

Mars is the fourth planet from the Sun and the seventh largest: \n\n      orbit: 227,940,000 km (1.52 AU) from Sun\n      diameter: 6,794 km\n      mass: 6.4219e23 kg\n\n\n Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet. (An interesting side note: the Roman god Mars was a god of agriculture before becoming associated with the Greek Ares; those in favor of colonizing and terraforming Mars may prefer this symbolism.) The name of the month March derives from Mars. \n\nMars has been known since prehistoric times. Of course, it has been extensively studied with ground-based observatories. But even very large telescopes find Mars a difficult target, it's just too small. It is still a favorite of science fiction writers as the most favorable place in the Solar System (other than Earth!) for human habitation. But the famous "canals" "seen" by Lowell and others were, unfortunately, just as imaginary as Barsoomian princesses. \n\n\nViking 2 Landing Site  Pathfinder Landing Site The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including Mars 2, the first spacecraft to land on Mars and the two Viking landers in 1976. Ending a long 20 year hiatus, Mars Pathfinder landed successfully on Mars on 1997 July 4. In 2004 the Mars Expedition Rovers "Spirit" and "Opportunity" landed on Mars sending back geologic data and many pictures; they are still operating after more than a year on Mars. Three Mars orbiters (Mars Global Surveyor, Mars Odyssey, and Mars Express) are also currently in operation. \n\nMars' orbit is significantly elliptical. One result of this is a temperature variation of about 30 C at the subsolar point between aphelion and perihelion. This has a major influence on Mars' climate. While the average temperature on Mars is about 218 K (-55 C, -67 F), Martian surface temperatures range widely from as little as 140 K (-133 C, -207 F) at the winter pole to almost 300 K (27 C, 80 F) on the day side during summer. \n\nThough Mars is much smaller than Earth, its surface area is about the same as the land surface area of Earth. \n\n Olympus Mons Mars has some of the most highly varied and interesting terrain of any of the terrestrial planets, some of it quite spectacular: \n\nOlympus Mons: the largest mountain in the Solar System rising 24 km (78,000 ft.) above the surrounding plain. Its base is more than 500 km in diameter and is rimmed by a cliff 6 km (20,000 ft) high. \nTharsis: a huge bulge on the Martian surface that is about 4000 km across and 10 km high. \nValles Marineris: a system of canyons 4000 km long and from 2 to 7 km deep (top of page); \nHellas Planitia: an impact crater in the southern hemisphere over 6 km deep and 2000 km in diameter. \nMuch of the Martian surface is very old and cratered, but there are also much younger rift valleys, ridges, hills and plains. (None of this is visible in any detail with a telescope, even the Hubble Space Telescope; all this information comes from the spacecraft that we've sent to Mars.) \n\n Southern Highlands The southern hemisphere of Mars is predominantly ancient cratered highlands somewhat similar to the Moon. In contrast, most of the northern hemisphere consists of plains which are much younger, lower in elevation and have a much more complex history. An abrupt elevation change of several kilometers seems to occur at the boundary. The reasons for this global dichotomy and abrupt boundary are unknown (some speculate that they are due to a very large impact shortly after Mars' accretion). Mars Global Surveyor has produced a nice 3D map of Mars that clearly shows these features. \n\nThe interior of Mars is known only by inference from data about the surface and the bulk statistics of the planet. The most likely scenario is a dense core about 1700 km in radius, a molten rocky mantle somewhat denser than

It averages between 91 and 94 million miles. You can check this by multiplying the speed of light (186,000 miles per second) by the time it takes light to reach the Earth (8 min, 16 sec.)\n\n30 NOV 06, 1711 hrs, GMT.

As everybody else noted, the theoretical space journey would take 300 years in earth terms or 298.5 years aboard ship.\n\nThis presents you for some challenges in your story-in-progress as you would need:\n\na) a long-lived character or characters like Robert Heinlein's Lazarus Long; or\n\nb) generations of people born and raised on board ship with new generations trained in running a spaceship; or\n\nc) the passengers kept in hibernation while the crew is manned by androids and advanced computers.

On average, 2,432,890.5 miles per day. (Mars orbital circumference of 888,005,041 miles divided by 365 days.)

The shuttle can't go to the moon.  It has never been.  It does not have the rocket energy to break the gravitational pull of the earth and reach a speed of approximately 25,000 mph to leave the earth!\n\nThe Apollo spacecraft would leave the earth at a velocity close to 25,000mph  and rapidly lose speed as they approached the moon.  At a precise point in the trajectory, the earth's gravitational field and the moon's would be equal their speed would be about 3000mph, and after that point, the moon began accelerating them toward itself until they fired the rockets and dropped into a lunar orbit!  The journey from Earth to moon using that method, is about 3 days.\n\nBTW, the max speed of the shuttles in LEO (low earth orbit) has probably never exceeded 18,000mph!  A LEO of 100 miles requires a speed of 17,500mph to stay in that LEO.\n\nAnd to the one that said it would take 10 hours, don't plan on being a physics major!  Leaving the earth's gravitational field is like throwing a rock to infinity.  Once it reaches infinity, the speed is zero.  When it leaves the earth it is doing 25,000mph but rapidly loses speed thereafter departing!

The shuttle needs to reach a speed of 17,500 miles per hour to stay in orbit.

hold on here, this isnt a short answer - \n    the Earth is on average 92Million miles from the sun, times pi for the circumforance and its roughly 290Million miles around.  divided by 365 for the number of days, the earth travels some 790,000 miles on one day, ya thats high on the odometer.  distance in one day divided by 24 hours comes to 33,000 MPH, now i did this on my computer but it does seem right, \n\nNow part 2, hang on here, big numbers ahead, the Solar System wihich Earth belongs to is roughly 26,000 Lightyears from the galactic core, (which has a Supermassive Black hole as heavy as 6 Trillion suns).  it take a quarter of a Billion years (250,000,000) for our solor system to complete one revolution around the galaxy. The circumferance could be some 80,000 Lightyears,  though i am not sure how to calculate the speed of the solar system.
