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 Interstellar Mapping and Acceleration Probe (IMAP) is a heliophysics mission that will simultaneously investigate two important and coupled science topics in the heliosphere: the acceleration of energetic particles and interaction of the solar wind with the local interstellar medium. These science topics are coupled because particles ...
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.
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 ...
Interstellar Probe (ISP) is a proposed NASA space probe designed to explore and characterize the heliosphere and interstellar space. The study was originally proposed in 2018 by NASA for the Applied Physics Laboratory. It would have a baseline launch between 2036 and 2041. [1]
The probe passed the heliopause at 121 AU on August 25, 2012, to enter interstellar space. [7] Voyager 1 is still active. In about 40,000 years the star Gliese 445 (AC +79 3888) and the Sun will fly past each other at a distance of 3.45 light-years, after being currently 17.6 light-years from each other, [ 8 ] with Voyager 1 coming as close as ...
The probe is the farthest spacecraft from Earth, operating beyond the heliosphere — the sun’s bubble of magnetic fields and particles that extends well beyond Pluto’s orbit — where its ...
Solar System space probes operational as of November 2024. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to ...
