A new type of rover called
the Mars tumbleweed is being
developed by NASA. This wind
driven rover might provide
a better understanding of the
Martian Surface.
Plus we investigate a new
robot that will help astronauts
in space. Called the Personal
Satellite Assistant or PSA,
this ingenious robot will move
freely in its environment with
the help of reduced gravity.
And Johnny Alonso finds out
how telescopes work. |
