Isn't it MPL reborn?
The 2001 lander reborn? I don't think so.
Isn't it the rebirth of the 1998 Mars Polar Lander, that went missing on its way to the south polar region? Maybe some of the science instruments from 2001 were added to the basic 1998 design, but certainly it's the same basic vehicle -- rocket descent as in 1998 instead of airbags as 2001 was to do.
