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 ]
Voyager 1 and the other probes that are in or on their way to interstellar space, except New Horizons. Voyager 1 transmitted audio signals generated by plasma waves from interstellar space On September 12, 2013, NASA officially confirmed that Voyager 1 had reached the interstellar medium in August 2012 as previously observed.
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
Dual asteroids probe Was expected to be a secondary payload on the Psyche launch. After the delay, it was assessed that Janus wouldn't be able to reach the required trajectory. Both spacecraft were placed into long-term storage. [50] Kazachok: 2022 Mars lander Originally part of the joint ExoMars mission with ESA, planned to deliver Rosalind ...
Interstellar Probe is the name of a 1999 space probe concept by NASA intended to travel out 200 AU in 15 years. [1] This 1999 study by Jet Propulsion Laboratory is noted for its circular 400-meter-diameter solar sail as a propulsion method (1 g/m 2) 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.

The Initiative for Interstellar Studies (i4is) is a UK-registered not-for-profit company, whose objectives are education and research into the challenges of Interstellar Travel. [1] It pioneered small-scale laser sail interstellar probes ( Project Dragonfly ) and missions to interstellar objects ( Project Lyra ).
