Is there a follow-on vehicle in the plans yet? Or is NASA just dropping the ball and walking away from the game? There is the Crew Exploration Vehicle to replace the shuttle and ISS escape vehicle. Orion is primarily a lunar exploration vehicle. Correction, it seems the CEV is the Orion. Except for...

By the way, does anyone know if the individual frames for this kind of image are available online? I'd like to try to see if I could do a better job of stitching than has been done on this image. Try http://marsrovers.jpl.nasa.gov/gallery/all/spirit.html . Don't know if this is what you need or not...

Yep, and all the "Moon walks" were filmed on a sound stage in Hollywood.
What you refer to as pavement tiles and fire hydrants are parts of the rover.

Re: Mars and the futur of solar exploration
Due to the difference in the distance from Earth to Io and Mars, missions to Io would be significantly more expensive.sinpix wrote:I was wondering why the focus was set on mars desert for exploration? IO the jupiter moon seem to have a interesting volcanic activity and the cost is probably the same.

:lol: No, but wouldn't that be fun. I could even do it in my car, even though it's not a DeLorean. Maybe you think I'm nitpicking, but c is the speed of light in a vacuum not the speed of light . Light, and its speed, is affected by the medium through which it passes. If this wasn't so, we wouldn't ...

No, you said the speed of light is constant. My point was that the speed of light is only constant in a vacuum. Since there is no complete vacuum in our material universe, the speed of light varies. Granted, that variance may be too small for us to measure, but it's there. c is the defined constant ...

So now I'm wondering about the images included in this calendar that NoelC and bystander referred to: are they all the images from 2007? Or even years prior to that? Or are they going to be what we see here on APoD proper this year? RJN , do you wish to answer this? I know on CFHT's Hawaiian Starli...

That's the spirit CC. Rather than enlightening those of us who are so misinformed and answer the questions posed, lash out with derogatory remarks. I'm sure you attract a lot of adherents to your philosophies with those methods. BTW, where does petroleum come from? Not the Milky Way, I'm guessing. :...

I repeat, the inability to place an upper bound on the size of the universe does not preclude the possibility the universe is expanding (or even contracting). It does not require the universe to be in a steady state. While we can place bounds on the size of the observable universe (even those bounds...

The Universe: 365 Days 2008 Box Calendar http://www.amazon.com/Universe-Days-2008-Calendar-Page/dp/0810988631/ I think this is the calendar RJN is referring to. I think Amazon has the title wrong since there are 366 days in 2008. The cover has it right: http://www.amazon.com/gp/product/images/08109...
