The Surveyor 6 spacecraft achieved it first.
Back in 1967 it landed on a lunar slope.
And with its remaining propellant, it became
the first spacecraft to 'liftoff' the moon's surface
during a 2.5 second vernier engine burn.

In esssence, Surveyor 6 'hopped' from one
location to another on the Moon, providing
opportunity to obtain stereo images of the Moon's surface.

Could the Phoenix spacecraft perform the same thing?...On Mars?
There's a high probability that the spacecraft will land on
somekind of sloped surface.
If the Phoenix spacecraft's vernier engine has a few grams
of propellant left, should it attempt to lift-off of the martian surface
to 'hop' to another location on the martian surface a few meters away?
