Now that's just silly. Everyone knows Lada is self-propelled.

Not trying to be negative here, but just realistic...I don't think this mission has a snowball's chance to accomplish all its goals. Shouldn't Russia try something a little less ambitious for it's first mission in 20 years than the longest sample return mission yet attempted? Perhaps an orbiter with a new instrument suite?

Honestly, I'll be amazed if this mission even gets into orbit.

What are your thoughts on JAXA and Hayabusa?

Hayabusa was a technology demonstration as a primary mission. JAXA knew it was a longshot to return samples. Also, JAXA has built up a broad, experienced talent base working on several planetary missions in the last 10-20 years. They have the engineering and scientific know-how well honed. Russia had that knowledge and, as shown in that BBC article, has lost it or it is pretty rusty. I think it's great that they want to start flying missions again, but I think they ought to start small. If Phobos-Grunt was a US mission, it would be New Frontiers class, most likely. Japan, China, and India have all started with (successful) but much smaller missions to get their feet off the ground.

They started small. 50 years ago.

Of course they did...and they had great success. Now they're starting over.

Like it or not - they're doing this. And 'I told you so' if it fails is really rather bad taste, because none of us is equipped with enough information about how well this mission has actually come together and how realistic and ambitious it actually is.

As discussions go, it's fairly rich in futility.

Coming back to the picture on post 327, surely this must be just a mock-up, not the real thing. I don't think they would transport the hardware like that without encasing it in some protective box or something.

In Soviet Russia, space probes put you in the box!

One would assume that they plan to put this into an oven or something for planetary protection purposes, right?

I'm not trying to act haughty and set myself up for "I told you so". If this works, I think it'll be fantastic!

No, we don't have much information about this, but I think there's enough in the media and we all know enough about NASA/ESA spacecraft to make some comparisons. This is a very ambitious mission done on a budget that's most likely nowhere near what a comparable mission would budget in the US or Europe. That strains credibility and makes me doubt its success possibilities. I think if most people reading this look at it objectively, they'd come to the same conclusion as I. Again...I'm not wishing disaster or failure. I just wish they'd improve their odds by shooting at a lot lower target.

How does that work exactly in the case of Phobos-Grunt? Do they have to sterilize to Mars surface standards as a precaution against accidental impact, or to the (presumably much less stringent, if any) standards for asteroids & other small bodies, or just do the standard stuff (nothing?) for straight orbiters?
