Interstellar Probe (1999)

Interstellar Probe is the name of a 1999 space probe concept by NASA intended to travel out 200 AU in 15 years. This 1999 study by Jet Propulsion Laboratory (JPL) is noted for its circular 400 meters diameter, solar sail as a propulsion method (1 g/m2) combined with a 0.25 AU flyby of the Sun to achieve higher solar light pressure, after which the sail is jettisoned at 5 AU distance from the Sun.
