abstract = "The main idea of this paper is to propose the construction of an
Escape Portal to send a spacecraft to the exterior planets, or
even to make it escape from the Solar System, using a Tethered
Sling Shot Maneuver (TSSM) with an asteroid. The construction of
this portal allows an unlimited number of maneuvers with the same
tether, which is very interesting when considering a possible use
for small satellites. This structure would be formed by a tether
that remains fixed in an asteroid. At the other end of the tether,
a large net is fixed, such that the only action required from the
spacecraft to make the TSSM is to hit the net. The net can have a
mechanism to open a passage to release the spacecraft when the
desired rotation is obtained. This technique would avoid some of
the problems that appear when assuming that the spacecraft needs
to carry a tether on board that would be released to hit the
asteroid just before the maneuver.",
