Europe Goes To Venus; Mars Comes to Us 172

Posted by michael from the frequent-flyer-miles dept.
JamesO writes "The BBC says that the ESA is going to Venus, reusing the Mars Express design. Also here. Launch seems to be expected in 2005." And knownsense writes "Space.com is reporting that Mars is coming to closer to Earth. It will be closer by around 191 million miles and will end up 85 times brighter about August next year. This apparently is the first time it's been this close since the Neanderthals."

Considering the Earth is about 92.5 million miles from the sun on average, and Mars is about 140 million miles out from the sun, and a mars year is approx 2 earth years, what's the big deal here?? We pass by close to Mars every 1.75 earth years or so.

      • Just like the Anonymous Coward said above, 1 mile is 1,609344 km. That's a difference of 0,009344 km for every km. Over a small distance, say from you to your neighbor, the difference is not quite important. But in this case we work with stuff in space, the distances are huge and that little difference would for sure cause the probe to miss its target.
    • Could be worse. If the ESA did that, not only would they have egg on their face but they'd likely face stiff EU fines for using non-metric units.

      We can see the surface of Mars pretty well, probes that we send to the surface Mars will survive for more then a few hours, and it's possible that humans may go to Mars in the next 20 years.

While I'm all for the Mars trip, and it probably should be first, I think we must go to Venus, because there is much there to learn, and because it is hard. The moon was hard once, and we did it. We can do it again!

        I know we won't get there soon, but I want to see us accomplish this by the time I die.

        The thing with Mars is that we know how to do it: We make a big enough ship with enough fuel to get there and back (Which we can do, it'd just be a lot). You put some hydroponics on board. It's tech we have.

        Venus would require the same, and a lot more to stay alive there. It's truly a new frontier; Mars is merely a barren one. There is something romantic about Mars, but Venus' environment will fight tooth and nail to keep us away from her.

      Before you even start thinking about sending someone to another planet, there's a zillion other things to think about first. How to build a ship, how to feed the crew, what are the long term effects of space travel, etc. We still have a ways to go. A Satellite could go there now.

(But, the two sweet Mars rovers the US is sending next year, and probes from Europe and Japan, will take advantage of the close proximity of Mars to Earth on this orbit to increase data rates slightly.)

      Second, NASA doesn't set the priorities for what it does. It doesn't have much flexibility in how it uses its budget. Its missions and expenditures are determined by Congress in each year's budget. I assure you that there are many people inside NASA who are chomping at the bit to break humans out of Earth orbit (including many very high-ranking people inside the agency). But, Congress has to unleash NASA, and fund any mandate it approves.

      If you want to send people on the most fuel-efficient path to Mars possible (which is almost necessary just to get them there at all, unless you're using a rocket better than anything we've ever built), you use a Hohmann transfer orbit, an ellipse which is tangent to the inner circular orbit (Earth's) at one end and to the outer orbit (Mars') at the other end. Even with a nuclear or better propulsion system, you wouldn't just point the rocket towards Mars and fire, you'd take advantage of your existing velocity in Earth's orbit to cut a sort of diagonal path between the two.

      Either way, an extra-close approach of Mars wouldn't cut very much time off the trip.

      They've become so addicted to safe, academic research in orbit or from afar that they've forgotten how to take that leap into the unknown which was (in my opinion) what made the early space program (Murcury, Gemini, and Apollo) truly great.

    • Unfortunately NASA missions cost Money, LOTS of it. And recently Congress has seen fit to cut their budget. Even the once untouchable International Space Station budget has seen significant cuts.

      Not really. Astronomical brightness measurements are logarithmic, and they have to be in order for us to notice any difference. A small bright point in the sky that's twice as bright as another one.. the human brain/eyes sees them both the same brightness (for the most part).

      To really notice a difference, you need something on the range of 10X (or more) brighter. 85X from its usual appearance isn't THAT different, it'll just make Mars (normally a small red dot) look a bit brighter than Jupiter (a slightly larger red dot). If you've never watched Mars over the seasons, you may not be aware that it does this every coupla years, just not to this extent - the last time it got really bright was in the mid 80's - when Mars was almost as close (to within 2 million miles) as it will be this time around.

      It's happened before, it's been measured, and yes, it really DOES get a lot brighter.

        Er, no, your 10x is wrong.

        Most people think "an order of magnitude" is a factor of 10. This is actually wrong, and I think it is the origin of your mistake. An order of magnitude is the old naked eye astronomer estimate of the just reliably distinguishable difference in brightness of two stars. A real astronomical order of magnitude is actually the FIFTH ROOT OF 100, which is a factor of almost exactly 2.5.

        If objects differ in brightness by a factor of 2, you can easily tell which is the brightest if you can see them both together.

        The factors influencing the brightness of Mars are:

        • Its distance from the sun (inverse square law)
        • Our distance from Mars (inverse square law)
        • The portion of the illuminated surface which we see - the variation is much less than with the moon or Venus because the orbit of Mars is outside our orbit.
        I rather think this adds up to a TOTAL POSSIBLE variation in the brightness of Mars of 85:1. It will not be 85 x brighter under optimum conditions, just 85 x brighter than when it is as its dimmest. So don't expect a supernova effect.

      The article states that next August, when mars gets the closest to it has ever been, it will be 34.6 million miles away from earth. The article later goes on to say that in 1988, Mars went through a similar (though less extreme) event that closed the distance to earth to 36.5 million miles.....Now I know the 2 million miles is still a huge distance when you think about it, but that's barely a 6% difference.

      Agreed. This is mostly a "numerical anomally" rather than something that is visually signficant. Close approaches happen about every 15 years or so, and most of these are probably within a few percent points of this coming distance.

      Although, it would be cool to come out side one night and see Mars close enough to find the missing Polar Lander with the naked eye :-)

      Mars is often a tough telescope target. Your eye has to be trained to see any significant detail on the disk. Otherwise it will just look like a small orange disk, roughly the size of a penny held at arms length through the scope, with maybe one or two dark but vague splotches and maybe light areas that mark one or both poles or some high clouds. A "slightly dirty pencil eraser edge on" is how I would describe the view.

      I was disappointed to see it at the city observatory at the last close approach. My little 60mm scope actually showed more detail (probably because I waited for a better time when it was higher in the sky.)

      I would suggest picking a good Saturn night if you ever go to a town observatory. Saturn, the moon, and Jupiter (in this order) make the most impressive viewing targets IMO. Mars will probably disappoint you visually. But it is cool to know you are looking at Mars, dispite the poor view.

      However, Saturn varies over time because of the ring tilt from our perspective. If you go during a year with a non-tilt, you won't see much ring detail. Similarly with the moon: it goes through phases (lighting angle), and some phases are not that great in a telescope. Jupiter is probably the only consistent object WRT appearence and appearent size. It won't shrink, darken, or tilt funny on you. Even the Sun's disk changes in activity every 11 years (if you view it through a filter and projection). Although it is true that Jupiter's red spot does fade in and out depending on the type of clouds it is next to, or if it goes behind the planet. But there is more to Big Jup than just the red spot. You can usually see 4 of its moons quite easily (as starlike specs) and at least 2 tannish cloud bands on the planet.
      • "Mars will probably disappoint you visually. But it is cool to know you are looking at Mars, dispite the poor view. "

        Not exactly. Mars disappoints very rarely. It has a distinctive red tinge. Infact when the sky is slightly hazy(due to vapour) like when all start are slightly dim, at that time mars is noticable because red light gets scattered the least. The best time is after it has rained and skys gone clear, the pollution leves are low, but water vapour content is high. Then you see the planed of war shine.

        Infact there is an interesting story. During WW2 over europe, Mars was very very visible!

        • Not exactly. Mars disappoints very rarely. It has a distinctive red tinge.

          I meant from a *telescopic* perspective. Yes, the color is quite distinct, but you can see that just with your naked eye and brighter yet with bonoculars.

          My personal experience is that the telescope does not enhence the color any from what the eye sees. (Unless bad optics make pretty rainbow tinges.) Then again, such things tend to be subjective.

          If you like red, then there are some nice red stars also. These are interesting because most are in their later stages of life, which our Sun will someday do also. IOW, looking at a red star is like looking at our solar system's future. Awe-inspiring and frightening at the same time.

          It would be like when people reach 70 years old, they bloat up into a big red blob, stay that way for a year or two, and then suddendly burst open violently. The old-folks home would be a bit more complicated to manage if that was the case.
      • I had built my own 6" telescope out of commerically made parts back in the 70's when mars was also at a close opporsition and well visiable. I think I was able to see the polar ice caps and some surface detail at 200X. Not too bad from NYC with a scope mounted on a home brew equatorial mount made out of pipes. I now have two 7" glass disks and hope to grind a mirror for a new scope, hope I can complete the project in time for mars in August. (If not mars will be close again in two more years, though not quite as good).

  • Why not send a manned mission to Venus? This planet is sending far too few people on interplanetary missions. I can't believe we still don't have a functioning lunar base!

    How is this planet going to survive on its own? IMO, we really need to start building settlements on other planets.Mars is probably a better choice than venus though, because of the somewhat less harsh atmospheric and temperature conditions.

    Nasa and Esa and the other ones are not daring enough. They should be given bigger budgets. Space is the future of the human race.
