The Voyager spacecraft, launched by NASA in the 1970s, have embarked on humanity’s most ambitious journey into the depths of ...

Astronomers are scrambling to gather data on a mysterious object that’s currently hurtling through the solar system.

“The interstellar probe will go to the unknown local interstellar space, where humanity has never reached before,” Elena Provornikova, ...

The proposed interstellar probe would be built from the bottom up to deliver the desired science, she added. To be clear, this is not a mission to another star.

Interstellar Probe is actually a heliophysics mission to understand the furthest reaches of the Sun’s influence, the heliosphere, and to dip our toes into interstellar space.

The trick, though, is surviving the extreme heat of this close encounter. For the greatest velocity bang for the buck, the probe must pass within a million miles of the sun's surface, or four times ...

Interstellar Probe is an entirely new class of mission designed to operate well beyond the Kuiper Belt. The 50 year period is a target for 1000 AU and based on optimistic ideas about how to find ...

The proposed "Interstellar Probe" mission would aim to reach 90 billion miles (145 billion kilometers) from the sun, pushing the limits of engineering know-how and space technology.

If the Interstellar Probe ever gets that far, its main mission will be to figure out how the space out there differs from the space in here—”in here” being the space near our star.

With the SLS, Interstellar Probe could leave Earth at a speed of about 9 miles per second. After looping around Jupiter, the probe would fall back toward the sun, picking up speed from our star ...

Engineering full-scale interstellar probes will likely require new materials, new tech and a whole new set of design parameters. But most of all it will require speed. Today’s fastest spacecraft ...

Only the Voyager probes have passed the heliopause, leaving the sun’s influence. New probes may one day study the interstellar medium lying beyond. NASA-JPL/Caltech.
