AN antimatter-aided space drive might bring deep-space missions within our
grasp. Engineers at NASA and Pennsylvania State University say that by the end
of the century, spacecraft could reach the edges of the Solar System and
beyond.
They believe an antimatter drive could lead to a one-year round trip to
Jupiter, a five-year trek to the heliopause—the boundary separating the
Solar System from interstellar space—and, in a 50-year trip, the Oort
Cloud, source of the comets.
Antimatter is a mirror image of the matter we see around us. Its particles
are identical in mass but opposite in electrical…
