Okay, we now have definitive pictures of VL1, 2, Spirit, Opportunity, and a Pathfinder coming up soon. So, now, what would the lost landers look like, starting with Beagle, MPL, and Mars 6, which will be the easiest to find of the landers. Just curious to hear your thoughts. Thanks!

Terminology point: The Soviet Mars landers, as well as the early Luna landers including successful Luna 9 and 13, Pathfinder, and MER landers are all HARD landers. (Also Venera 4 through 8.) None of them were landings you could walk away from, the payloads were "armored", and the vehicles were not attitude controlled after touchdown.
The US Surveyors, the later Soviet Lunokhod carrying and Sample-return-vehicle carrying Luna landers, The later Soviet Venus landers, the US Vikings, Mars Polar Lander, Phoenix, and MSL are all soft landers. The Deep Space 2 probes were impactor/penetrators, while the US Rangers and Deep Impact probes were impact missions. |

The Deep Space 2 probes were impactor/penetrators, while the US Rangers and Deep Impact probes were impact missions. And the Ranger seismic capsules were also rough landers (NASA uses 'rough' in their SP-4210 Lunar Impact: A History of Project Ranger, and to be honest I think 'rough' is a better description than 'hard'!). NEAR, Hayabusa, Phobos 1&2 and Phobos-Grunt are in a class of their own! 'Featherweight'? Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!
