Interstellar probes such as the Voyager program were made only with the intent to visit the outer planets, with the added interstellar mission as a mere bonus. Their lifetime had never been expected to be much longer than 12 years at the most, but the probes have lasted for upwards of four decades thus far.
Interstellar Heliopause Probe (IHP) (2006) A technology reference study published in 2006 with the ESA proposed an interstellar probe focused on leaving the heliosphere. The goal would be 200 AU in 25 years, with traditional launch but acceleration by a solar sail. The roughly 200–300 kg probe would carry a suite of several instruments ...
Project Dragonfly is the first conceptual design study that assesses the feasibility of a laser-propelled interstellar probe, conducted by the Initiative for Interstellar Studies. [ 3 ] [ 4 ] Contrary to past unmanned interstellar mission studies such as Project Daedalus and Project Icarus , the focus is particularly on a small spacecraft. [ 4 ]
first probe to cross the asteroid belt; first Jupiter probe; first man-made object on an interstellar trajectory; now in the outer regions of the Solar System but no longer contactable 1972-012A: Pioneer 11: NASA: 4 December 1974 flyby success went on to visit Saturn 1973-019A: Voyager 1: NASA: 5 March 1979 flyby success went on to visit Saturn ...
TAU concept art Stellar parallax is the basis for the parsec, which is the distance from the Sun to an astronomical object that has a parallax angle of one arcsecond. (1 AU and 1 pc are not to scale, 1 pc = ~206265 AU) What TAU would do is use its distance from the Earth to make the parallax measurement, so rather than just 1 AU as with an Earth-based annual parallax it would be hundreds of AU.
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.

Starlight aims to accelerate the spacecraft with powerful lasers, a method the project refers to as DEEP-IN (Directed Energy Propulsion for Interstellar Exploration), [2] thus allowing them to reach stars near the Solar System in a matter of years, in contrast to traditional propulsion methods which would require thousands of years.
