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 ...
The sub-probes would fly past their targets, still travelling at 12% of the speed of light, and transmit their findings back to the Daedalus' second stage, mothership, for relay back to Earth. The ship's payload bay containing its sub-probes, telescopes, and other equipment would be protected from the interstellar medium during transit by a ...
Of the 10 science instruments Voyager 1 started its journey with, four are currently gathering data on its cosmic environment, and each year, the spacecraft loses more of its precious power supply.
Pioneer 10 (originally designated Pioneer F) is a NASA space probe launched in 1972 that completed the first mission to the planet Jupiter. [6] Pioneer 10 became the first of five planetary probes and 11 artificial objects to achieve the escape velocity needed to leave the Solar System .
This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: It includes: All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes .
A satellite called S73-7 that had been missing since the 1990s mysteriously turned up again this week, raising the question of how the Department of Defense lost the interstellar probe in the ...
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 ]
