Thanks. The image was already online, so I thought I would speed up posting it. Why are they disabled? Wouldn't link tags be more dangerous? <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

Mods have to view the images first in case they are inapropriate. Shame, but there you go.

Where does Mars Express clock in? What about the Viking orbiters?

<b>Mars Express</b><br /><br />Mass<br /><br />1200 kilograms in total (including 113 kilograms of payload, 65 kilograms of lander, and about 430 kilograms of propellant).<br /><br />Dimensions<br /><br />1.5 by 1.8 by 1.4 metres (excluding solar panels). With solar panels extended, Mars Express measures about 12 metres across. <br /><br /><b>Viking lander</b><br /><br />Length: 3 m (10 ft)<br />Height: 2 m (6 ft 6 in)<br />Length: 3 m (10 ft)<br />Weight, unfueled: 576kg (1,270 lb)<br />Manufacturer: Martin Marietta for NASA<br />Launch Vehicle: Titan III-Centaur

Would anyone care to add the other Mars orbiters to the picture?<br /><br />* Soviet/Russian designs (both with and without the lander when a lander was included)<br />* Mars Express<br />* Mars Climate Observer<br />* Mariner models<br />* Viking (both with and without the lander)<br />* Mars Observer <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

See what you can launch when you give that Delta II sounding rocket a rest?

I think he was just remarking how much bigger the spacecraft can be when you've got a bigger booster to launch it with.<br /><br />However, it's not really true. Bigger boosters have been available; the budget hasn't been, so the spacecraft have been smaller.<br /><br />A really interesting comparison would be MRO to a Viking complex (with both orbiter and lander, as they were launched as a unit). Those required Titan 3 launch vehicles. Very powerful boosters. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

I've been coping with a crappy Internet connection at work or I'd've tried. But now I'm home. <img src="/images/icons/wink.gif" /> I'm watching the US premier of Dr Who, so I'll work on that during the commercials. <img src="/images/icons/wink.gif" /><br /><br />Ooh, it's back -- gotta go! <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Okay, this is all from astronautix, so it may not be entirely accurate; they dont' have complete information and sometimes are a little inconsistent in how they sort things. (Is a cruise stage included or not, for instance.) I've got name, launch date, mass, and mission (with a brief note if it failed completely; there were some partial successes which I've not noted as anything special):<br /><br />#Mars 1M s/n 1 - 10-10-60 - 640 kg (launch failure)<br />#Mars 1M s/n 2 - 10-14-60 - 640 kg (launch failure)<br />#Sputnik 22 - 10-24-62 - 894 kg (launch failure)<br />#Mars 1 - 11-1-62 - 894 kg (contact lost prior to Mars flyby)<br />*Mariner 3 - 11-5-64 - 260 kg (fairing failed to separate)<br />*Mariner 4 - 11-28-64 - 260 kg (1st successful Mars flyby)<br />#Zond 2 - 11-30-64 - 925 kg (contact lost prior to Mars flyby)<br />*Mariner 6 - 2-25-69 - 412 kg (Mars flyby)<br />*Mariner 7 - 3-27-69 - 412 kg (Mars flyby)<br />*Mariner H - 5-9-71 - 985 kg (launch failure)<br />#Cosmos 419 - 5-10-71 - 4647 kg (stranded in Earth orbit)<br />#Mars 2 - 5-19-71 - 4647 kg (Mars orbiter; Mars lander failed on landing)<br />#Mars 3 - 5-28-71 - 4647 kg (Mars orbiter; first Mars lander)<br />*Mariner 9 - 5-30-71 - 985 kg (first Mars orbiter)<br />#Mars 4 - 7-21-73 - 3440 kg (MOI failed)<br />#Mars 5 - 7-25-73 - 3440 kg (Mars orbiter)<br />#Mars 6 - 8-5-73 - 3440 kg (failed soft-lander)<br />*Viking 1 - 8-20-75 - 3399 kg (Mars orbiter, Mars lander)<br />*Viking 2 - 9-9-75 - 3399 kg (Mars orbiter, Mars lander)<br />#Phobos 1 - 7-7-88 - 2600 kg (failed after orbit insertion)<br />#Phobos 2 - 7-12-88 - 2600 kg (failed after orbit insertion)<br />*Mars Observer - 9-25-92 - 2573 kg (failed during MOI)<br />#Mars 96 - 11-16-96 - 6180 kg (launch failure)<br />*Mars Pathfinder - 12-4-96 - mass not given (Mars lander)<br />*Mars Global Surveyor - 11-7-96 - mass not given (in Mars orbit)<br />@Nozomi (Planet-B) - 7-3-98 - 258 kg (failed MOI; heliocentric orbit)<br />*Mars Polar Lander - 1-3-99 - 576 kg (failed on landing) <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Yeah, but no graphic to compare them. I would simplify it by eliminating the probes that did not reach the Mars vicinity. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

Well, I only had the commercial breaks to work in. <img src="/images/icons/wink.gif" /> Bear in mind, there aren't neccesarily good pics for a lot of the Russian ones, and of course you need more than just wet mass estimates to scale those appropriately. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

The problem is I need to see something visually to understand it. So without a drawing, all I have are a bunch of numbers. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

It's hard to believe but it's almost time for MRO to start work. <div class="Discussion_UserSignature"> <em><font size="2">Bob DeWoody</font></em> </div>
