You would be able to see the dark and light "albedo" regions of the planet and find the dust storm based on them.The features of Mars can be quite subtle. It will help if you are warm, sitting comfortably, and able to watch for a long enough period to experience good moments of atmospheric seeing.The more time you observe, the greater your chances of getting those unusual moments of clarity. Many, MANY people will spend about 5 minutes looking at Mars in variably moderate seeing and give up on it. This is not the way to see the most your telescope has to offer.Mike [ Reply to This | ParentRe:Viewable with My Telescope? by matr0x_x (Score:1) Friday October 28, @08:08PMAnd as I've noticed by CiXeL (Score:2) Friday October 28, @09:29PMRe:And as I've noticed by 19thNervousBreakdown (Score:1) Friday October 28, @09:51PM1 reply beneath your current threshold.

Mars has a bad habit of becoming engulfed in planet wide dust storms which almost totally hide the surface features of the planet.I am sure many amateurs like myself would prefer NO dust storms on Mars while it is so close to the Earth, and so favorably positioned for Northern hemisphere observers. This has been a great Mars apparition so far, I've watched it growing in the eyepiece since August. If the dust stays clear, Mars will be large enough to enjoy until almost February. If it turns into a cloudy red ball, well...This page shows a dust storm growing from the 2003 apparition of Mars, and a picture of the dreaded featureless red ball.http://science.nasa.gov/headlines/y2003/09jul_mars dust.htm [nasa.gov] [ Reply to This Re:Mars Dust Bad!

But there is the question of coverage . . . the big expensive telescopes just don't have the resources (ie, observing time) to image Mars (or any other particular object or planet) several times a night whenever that object is visible.But amateurs do have the observing time available and they do the work . . . result is, amateurs do a lot of the meat & potatoes of keeping an eye on things like Mars or Jupiter.More of Sherrod's photos of the beginning of the Mars dust storm [arksky.org] and numerous photos of this Mars apparition [arksky.org]. Since Sherrod is imaging Mars pretty much every possible night, he was on the spot to catch this as it happened . . . Also, if you haven't been following trends in astro-imaging, you may be amazed at the quality of images people are now getting using relatively modest telescopes (generally 8 to 14 inch scopes, the sort of thing you can buy basically off the shelf for maybe $800 to $5000) coupled with inexpensive webcams.See numerous amateur astronomer's images of this apparition of Mars here [arizona.edu].

It would therefore be an almost impossible place to visit. Elton John made a similar point. And if he can agree with the nuns, then there must be some truth to it.Yes that is a great idea. Let's base our whole opinion of a Mars mission on the opinion of a bunch of nuns and a muscian. They are truly more qualified than a sicentist.

Until we knocked a lot of the gas out of the atmosphere, we'd have to live in pressure suits or stay high in the air. Also, the atmosphere is full of sulphuric compounds which would have to be neutralised. Venus already has a lot of water, however, all the surface water has been vapourised -- the planet suffers from a run away greenhouse effect.

Also, a "couple hundred knots" of wind isn't as impressive on Mars as it is on Earth. Winds on earth that qualify as hurricane speeds on earth, would feel more like a light breeze on Mars due to the low air pressure.Also, if we want create a colony on another celestial body besides the moon, Mars would be the best choice. Venus is way too hot and has major acid rain. Moons are a bad idea because prolonged exposure to low G environments can cause health problems. Mars, even if it has high winds, is the most similar to earth. It would also be easier to colonize with our current level of technology then venus would.
