NASA’s ATHLETE (all-terrain hex-limbed extraterrestrial
explorer) lunar rover chassis comprises six wheels each mounted
onto an articulated leg. Each of its six wheels has a diameter of
0.71 m and width of 0.2 m. The articulated legs allow the rover to
step over obstacles up to 1.5 m in height above the lunar surface.
The mass of the chassis itself is 850 kg. It carries a 2.34 m
diameter by 3.66 m long habitat module which fully laden masses at
15 metric tonnes, i.e. total rover mass of 15.85 tonnes on the
Moon.
1. The system is modular so two elastic mobility system tracks can
replace the six wheels. The two continuous tracks each have a
ground contact length of 3.66 m by 0.2 m width. Assuming that the
track curvature has the same diameter as the wheels (0.71 m),
calculate the mass of the track required to support the lunar
habitat module if the elastic loop is constructed from aluminium
and titanium respectively.
