New Dust Storm on Mars Viewable with Telescopes

starexplorer writes "Space.com is reporting that a large dust storm has just began on Mars, just as the Red Planet has gotten in prime viewing location this weekend with a decent sized backyard telescope. An amazing stroke of luck for everyone this weekend! Three PDF Viewing Guides, movies and more available to help get you started."

    I've got a Meade 125-ETX, I wonder how visible this will be. The last time Mars was close and I lugged the scope out It was mostly a brown smudge.

    Mars will be 43,137,071 miles from Earth at around 11:25 p.m. ET Saturday.

    That's 13,803,862,720 rods for the anti-science crowd.

      With a Meade 125-ETX, assuming 1) the system is working well, and 2) you keep your diagonals and eyepieces clean, and 3) your atmospheric seeing conditions are OK, you should be able to observe the dust storm as a bright patch on the planet. 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.

      This year Mars is near the zenith at opposition which means less air between us and our target!

      Actually, there's probably almost the same amount of air between us and Mars... just a little bit less space. :-) </nitpick mode>

      Well, there is more air between us and Mars when Mars is just rising, and less air once it reaches zenith (directly overhead). Any astronomer will tell you that they prefer to view things near the zenith because if seeing (atmospheric conditions like blurring) is bad, it won't be as bad near the zenith.

      However, their necks and backs may not agree.

  2. Mars Dust Bad! by deathcow · · Score: 5, Interesting

    While this is exciting for amateur astronomers to see a process like this happening on Mars, it's also very forboding and ominous. 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.

      It looks impressive from here but I am not sure how dense the dust really is. If a storm like this impacts on one of the two rovers currently operating there it would definitely cause some power supply problems for them, but I don't know if this would be immediately fatal.

    30 years ago, I learned in frickin' catholic elementary school that Mars had high-speed winds (on the order of a couple hundred knots), common massive unpredictable dust storms, and other nutty stuff going on, including weird volcanoes and possible large magnitude earth quakes. 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. Also, Im not sure but I can't find anything about plate tectonics currently being active on Mars. I know there is evidence supporting that it did happen but I don't know if it is currently happening. Do you have any information.

    It's not about going to Mars because its a pretty fun place to visit like Disneyland. It's about going to Mars because of a desire to learn about new environments and new science and new technology.

    We are like 15th century Europe about to start exploring the Americas, it's a huge wild dangerous place filled with great unknowns and fantastically huge potential. Should we stay home in our safe little castles or step out into the next frontier and learn how to live there and what its pitfalls and rewards are?

    No. Due to the lower gravity and atmospheric density on Mars, it is very easy for even light winds to whip the dust into what look like impressive storms. However, something reasonably solid such as a rover can (in theory, wouldn't recommend it due to the dust abrasion etc) plough straight through the middle of whirlwinds etc. with no issues of being flung around.

    This is a great example of the type of work that can and is still being done by amateur astronomers.

    (Actually Clay Sherrod, who seems to be the first to have imaged this storm, isn't an amateur but he's active in the ALPO Mars section which consists mainly of amateurs and he images at a small observatory, not some huge government funded observatory with various gigantic telescopes.)

    The thing is, the big expensive government funded telescopes, or the Hubble, for example, can take better photos of Mars than amateurs can. 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 and numerous photos of this Mars apparition.

    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. (warning--LOTS of images on that page).
