Forget the currency exchange rate; if you are planning to spend your next vacation traveling the solar system, you'd better bring your calendar converter. Of course, we all realize that the days and years will be different due to the various orbits and rotation rates but what about months...

Could it be...? :eek: http://news.bbc.co.uk/2/hi/science/nature/3577551.stm

http://www.guardian.co.uk/life/news/story/0,12976,1179710,00.html personally, i think we need to wait until we have a more conclusive look at what current life there is (if any) on Mars and then decide if this is an ethical idea...even then, it may be absolutely impracticle...

Another “MAJOR” finding by Mars rover to be announced Tuesday. On Tuesday, March 23 at 2pm, NASA and the Mars rover team are going to make another announcement about a major scientific finding by the rover Opportunity. No word yet on what the discovery is, but it should be big since they’re not...

I'm doing a research paper <again> and I need information on the Mars Rovers (Opportuniy or Spirit or both) and what materials make up those rovers and how physics is applied there etc...im really just starting to learn physics so i don't know much

So I was playing around with Celestia and watching last year's transit of Mercury and this year's transit of Venus. They seemed pretty accurate to diagrams I've seen for ingress/egress locations. Then I got an idea. I flew to Mars and went looking for a transit of Earth, and to my surprise I...

http://www.ansto.gov.au/info/press/2004/p02.html Thought I’d link this article, as I’m quite sure those in the USA didn’t hear about it. Reminds me of the article I scored from Pravda (Russian newspaper) a few years ago, regarding the Hungarians proving that life exists TODAY on Mars (they...

First view of the Earth from the Martian surface...Orion constellation...partial solar eclipses. Fun stuff. http://www.cnn.com/2004/TECH/space/03/12/mars.earth/index.html

i have thought of this can we actually live on Mars ?? well there is no water, no air, its too damn hot, and there are lots of dust storms and stuff.. but didnt anyone think of an idea to live in those conditions ? i don't know about creating water but, what if we send a probe with...

Hey there I just saw a show on Discovery about spacetravel, and a little question arose as the show ended: In the documentary, by my observations aged 3 -4 years, they mentioned a plane going to Mars to explore the planet. In the animations it looked a lot like conventional airplanes with...

http://www.cnn.com/2004/TECH/space/03/02/mars.findings/index.html p.s. Thanks to Evo for the heads-up on this.

I want to go to Mars. Why not me? I am older and if worse came to worse, say we couldn't get back, then I would not be panicky or depressed about it. I don't want to go to the Moon, only Mars. Maybe there is something there. I wouldn't mind being "Robinson Caruso on Mars". I have much...

i have ben studying Mars for a while now and I was just wondeering about peoples views on weather man will ever walk on Mars in this life time?

quotes: In the wake of plans by President George W Bush to put a man on Mars, and a rival European effort, a £13 million project to launch 15 "mouse-tronauts" has been announced that will provide a stepping stone for the ambitious manned missions. Astronauts living on space stations have...

Should trillions of dollars be spent trying to go to the Moon and Mars?

They say it is about 24km North of the center of the predicted landing zone, in other words right on target. It began communicating as soon as it hit the ground. Not to bad, should be a interesting few weeks ahead.

There was no mention of Moon bases and Men on Mars in his SOU address last night, or at least according to the review I listened to (BBC?). Is this good news?

I have a few questions about Mars I hope you can enlighten me about. Firstly,what does the sun look like from Mars,that is the comparative size of the disk with that on Earth? I saw a very poor picture somewhere on the web but couldn't really get a handle on it,perspective/lack of points of...

What type of Spacecraft would you design and what propulsion system would you use? Her are my thoughts, what are your? Can we, as Forum members, pool our ideas and come up with a feasible design? I say, let's try. 1. Crew size: 1. Commander and Pilot. 2. Spacecraft Systems...

What credit should President Bush receive for suggesting a manned Mars trip? Does he scheme to one-up Kennedy, evade failed policy, or nationalize the world (all for ~$500,000,000,000)?

The surface of Mars, the loss it’s of atmosphere and the fate of earth. I think that what we would expect on Earth (the potential of the Earth's electro-magneto-dynamic) is not on Mars. We will not find a molten core, nor a strong atmosphere. The rotational speed of Mars is adequate but the...

"Trying" to go to Mars will be the STUPIDEST thing America can do! Folks, we just cannot afford, at this time in our History, to try to go to Mars. First, the Astronauts would not survive. How on Earth could they carry enough food, water, CO2 filters, a waste disposal system for what, maybe 2...

Listening to Richard Hoagland on late night radio and visiting his website : www.enterprisemission.com I see a lot of pictures of the planet Mars and lately a few shots taken of the Mars landscape showing a lot of rocks and Mars soil...only he claims these "Rocks" are possibly ancient...

I just saw the live broadcast of NASA Caltech Spirit on Mars. Without knowing any background or foreground, I saw a Chinese man overreacting... Looks unnatural. Anyone know who he is??

I have figured out what happened to the Mars probe! Click on the attachment photo to find out...

As part of Beagle 2 interest, I thought I'd post the mailshot I recieve. Latest:Beagle 2 is currently traveling the last miles of its journey to the Red Planet alone and without any propulsion systems of its own. Thanks to the careful alignment of Mars Express on 19th December and accuracy of...

Face on Mars! True nature revealled! Is it less exciting that it's a mesa? Doesn't the pursuit of science generate its own excitement, wonder, and awe? http://antwrp.gsfc.nasa.gov/apod/ap031214.html

Not the PF Mentor! Very cool pic, from the Viking 2 spacecraft , of the Martian moon Phobos over the volcano, Ascraeus Mons. http://antwrp.gsfc.nasa.gov/apod/ap031129.html Nice visual perspective on how big this moon is, how large the shield volcano is. For comparison, many a comet is...

I've just been reading the latest 'discoveries' regarding the infamous 'Face on Mars' at Cydonia ... http://www.enterprisemission.com/paper_1/paper_1.php?page=paper1 It's pretty intense stuff. Richard Hoagland and his entourage seem pretty convinced about its composition and origins - even...

So, i was on vacation and watching the New Tom Green Show, (which is much better than the old one imho) and this absolutely hilarious theoretical physicist guy was on and he was talking about how on the 27th of this month that Mars will be closest to the Earth than it's been in... i forget how...

"PASADENA, California -- The two moons of Mars -- Phobos and Deimos -- could be the byproducts of a breakup of a huge moon that once circled the red planet, according to a new theory." http://www.space.com/scienceastronomy/mars_moons_origin_030729.html

I hope this is not a duplicate topic, if it is, I apologize... I watched on science news the other night that Mars is to venture its closest to Earth then most people will see for a long while...and also a mission is planned to land on mars...any news, topics already started or info on this?

In 1976, a Viking probe landed on Mars. Strange activity in Martian soil that was similar to microbes giving off gas was detected. A subsequent test for organic matter turned out negative and it was concluded that Mars was dead. However, former mission scientist for NASA Dr. Gil Levin says...

On CNN, I saw a picture of Earth from mars. Earth looked blurry. Why is that?

very cool http://www.cnn.com/2003/TECH/space/05/22/earth.mars.ap/index.html

How long do you think it will be before we land the first manned spacecraft on mars? How close are we to being able to do this at present?

I'm not one of those that sees artifacts in every other MGS photos, But these two have me scratching my head. The first shows what looks like regular grid lines layed out in almost a street-like pattern. http://home.teleport.com/~parvey/mars1.gif This second one also shows something...
