Speak for yourself. I plan to live to at least 150,000 years of age. I'm sure I'll see better.

But when are they going to probe Uranus?
Since Mars is so close, it's a shame that more people haven't read "The Case for Mars" (see here, and no, I am not affiliated in any way), as now would be a very good time to put some of the principlesinto practise and land someone on Mars!

Never again in our lifetimes will the Red Planet be so spectacular!
This month and next, Earth is catching up with Mars, an encounter that
will culminate in the closest approach between the two planets in
recorded history.
The next time Mars may come this close is in 2287.
Due to the way Jupiter's gravity tugs on Mars and perturbs its
orbit, astronomers can only be certain that Mars has not come this close to
Earth in the last 5,000 years but it may be as long as 60,000 years.
The encounter will culminate on August 27th when Mars comes to within 34,649,589
miles and will be (next to the moon) the brightest object in the night sky.
It will attain a magnitude of -2.9 and will appear 25.11 arc seconds wide.
At a modest 75-power magnification, Mars will look as large as the full moon to
the naked eye.
Mars will be easy to spot. At the beginning of August, Mars will rise in the east at 10 p.m. and reach its azimuth at about 3 a.m.
But by the end of August when the two planets are closest,
Mars will rise at nightfall and reach its highest point in the sky at 12:30 a.m.
That's pretty convenient when it comes to seeing something that no human has
seen in recorded history.
So, mark your calendar at the beginning of August to see Mars grow
progressively brighter and brighter throughout the month.

Why go to Mars when you've got Rekall?
>... and about those lobotomies, statistics show that it's safer to use Rekall than to travel to the red planet itself.
I'm delightfully interested in that Agent-package... Hmm...
What's so bad about being lazy? What if there was a war and nobody showed up?
If you read the fucking story, you'd note that the *poster* says he thinks that Nasa has been launching probes (they've launched two to Mars in recent months, rememeber?) to take advantage of this phenomenon. Launching them on "the day" doesn't really accomplish anything, because by the time your probe is launched, Mars is already heading farther away (remember, probes take longer than a day to get to Mars?).
I bet that someone from that zetatalk or whatever it was will claim this is the famed Planet-X which was meant to destroy life as we know it back in may/june.
"Quick, get to your safe locations again, we *really* mean it this time, honest!"
Anyway, its always nice to see there is (I use this term lightly) "life" outside of this small planet. Now 34,649,589 miles doesnt seem to far. I'll definately have to have a look.
Launching a mission on the date of closest approach would be poor timing. To take advantage of this, missions would need to be launched prior to that date (how long before can be figured out, but I don't know the data to do so). If you launch on the day when Mars and Earth are closest, you'll immediately begin chasing Mars and the trip will not be optimal. If instead you launch before hand, you're travelling towards mars while it's travelling towards you. The rate of movement may be so minimal that it won't make a difference, but I don't know.
No, it would have had to have been launched before the date of closest approach. If you launched a probe, etc. at Mars (coming towards you), they'll meet up much sooner than if you launch on the date when Earth and Mars are actually nearest (since they're traveling towards each other). If you actually ended up launching on the day that Earth and Mars are closest, then Mars would be moving *away* from the probe shortly after launch, thus making it harder to get to.
Get your affairs in order, the end is near! This would be the perfect time for the Zhti Ti Kofft, as the Martians call themselves, to invade and conquer.

As an aside, about an earlier event fromThe Universe Today:
A rare astronomical event will occur in May 1999- Mars will be the closest it ever gets, only 52.8 million miles. In addition, the Red Planet is in opposition, which means its face is completely lit up by the Sun. Amateur astronomers will be able to see normally obscure features like the polar caps and canyons.

For global views of Mars check here, however at this time of year (August) Mars is enveloped in planet wide dust storms, so the view is going to be obfuscated by all that red grit...if you want to check out before and during storm pics then click here.

That's no mars, it's a space station!
Here's the Snopes entry on it. Essentially, while it's technically true that this is the closest pass in 60,000 years or so, to most observers there won't be any appreciable difference between this pass and the semi-close passes it makes every 15 years or so. The interest lies mainly in how this makes it more easy to launch probes. (and note the similarity in wording between the Snopes version and the post. Hmmm...)

Got the wife and kids in a truck, and we're gonna head to the hills for a while. Got meself a shotgun... just in case those Martians come for ME!
Sorry, but my karma just ran over your dogma.
But it's NOT the best time to send something to Mars. It would have been best to launch something about a year and a half ago, when mars and earth were moving towards each other, and have the probe REACH Mars when it starts getting farther away.

Users of Celestia (the stunning open-source galaxy simulator) can verify this and a whole lot of other space events as Mars is, at August 27, 0.373 AU from Earth. When I'm typing this, Mars seems to be 0.410 AU from Earth.
1 AU = 149,597,870.691 km
0.373 AU = 55800005 km
0.410 AU = 61335126 km
The values seem to be slightly off (by around 1%) when compared to the article's shortest distance, from the approximated planetary orbits.

It's fairly big already - about 20 arcseconds I should think - and I've taken a look a few times already the past few days (in my 10" F5 reflector, 4mm ultrawide plossl eyepiece, magnification about 300x). Why look now before opposition? Because it has already passed it's maximum declination in mid-to-late July, even then at about only 25 degrees above the horison where I am, and is now getting lower each night. Even at maximum elevation it was so low that atmospheric distortion mucks up the image quite badly.
In fact, although this is supposed to be the closest opposition for maybe the past 60,000 years, the low elevation means it's not really such a great observation opportunity for astronomers in the northern hemisphere. I was just about able to make out the southern polar cap and some blurred greyish surface features in the southern hemisphere.
If you live further South though, there should be some really spectacular views with Mars almost overhead. And it's so bright that you don't need a large telescope - just a good one. And an equatorial mount is a must, because the damn thing moves so fast.

2xUS, 1 European & 1 Japanese probe.
Of those to whom much is given, much is required.
Slashdot has just made "Close Encounters of the Mars Kind" the most read story in the recorded history of Elite Geek (and by quite a large margin).
Actually the Japanese probe was launched over a year ago (can't remember the exact launch date) and suffered a engine failure. They did some orbit changes and had it swing by Earth agian before heading to Mars a second time. This time how ever it's on a free trajectory and shouldn't need much engine use. They are running extremely low on fuel though and some of the parts have begun to fail. They're not completely sure the probe will make it. But it does result in a swarm of probes heading towards Mars and hopefully will result in alot of data coming back from various parts of the planet and from orbit all at the same time which will give scientist a better overal view of the planet.

In December 2001, I interviewed the Medical Director of the Mars Society for Cyberista. The story is here. Everybody in that organization is superb in their field. Dr. Czarnik was an excellent interview subject.

I think it would be great if some national radio show would rerun Orson Wells radio adaptation of the H.G. Wells classic "war of the worlds" which aired on halloween night in the 30's. For those of you who never heard it, it so panicked the east coast that most of it's residents thought the martians had invaded the world LOL
An article in the Most popular mars daily paper reads:
Little green men on Mars are being warned about the upcoming close encounter with our appearently beautiful neighbor, Earth.
The inhabitants of the planet Earth are known to be greedy, territorial and suicidal (they have enough nuclear power to blow their planet 10 times over. We still don't understand why they call our planet "The God of War"). They have already consumed their home planet, and are expected to be looking towards us during this encounter. Some of them may even try to hop on to our side. Reports confirm 2 or 3 rocket ships launched earlier this year moving towards Mars.
Continue staying underground in caves. Build no canals, humanoid faces or any other structures on the surface reflecting presence of intelligent life on our planet. continue the planet wide dust storm as it will repel the earthlings.
Earth will probably stink because of high leavels of pollution.

of the 2003 distance in 2208, a 0.007% difference - and came within 12,000 miles in 1924, which is 0.03%, according to The Opposition Cycle Of Mars, by Jeffrey Beish.
Hauled out my little 8" equatorial reflector to a dark sky site Friday night and had spectacular resolution of surface features. Southern polar cap was crystal clear as were many other surface features that I can't describe very well without a map of Mars handy. That was only at 120-240x. 2 years ago, at the last opposition, I looked at Mars through a scientific grade 12" refractor, and it was just a featureless orange ball. This year is much better. The closeness aspect isn't really so much of an improvement (from an observational standpoint) as the lack of dust storms. I just hope I get a chance to point the big refractor at it again this time around.....
Some sort of weird thing is going on in Northern New Jersey. Not sure what it is, but evidently there was some kind of an explosion and communications with a town was lost...
This is my sig.
Starry Night has released a nice little util that tracks the approach to mars. Its pretty neat.
