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 ...
Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program to study the outer Solar System and the interstellar space beyond the Sun's heliosphere. It was launched 16 days after its twin, Voyager 2 .
An enduring mystique surrounds the Voyager 1 and 2 probes. Launched two weeks apart in 1977, the twin probes changed the way we see our solar system, sending back stunningly detailed views of ...
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 ...
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 .
The Voyager program is an American scientific program that employs two interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment to explore the two gas giants Jupiter and Saturn and potentially also the ice giants, Uranus and Neptune - to fly near them while collecting data for ...
The Interstellar Boundary Explorer 's mission is to study the nature of interactions between solar wind and interstellar medium at the edge of Solar System. 2009 North Korea: Kwangmyŏngsŏng-2: Earth: Failure: Kwangmyŏngsŏng-2 failed to orbit, possibly due to the rocket's third stage not separating properly. Europe: Planck: L2: Success ...
