NASA has reversed course on plans to curtail the New Horizons spacecraft’s planetary science studies following a rebellion among the mission’s leaders

Researchers have gained a new view of the journey ahead for the twin Voyager spacecraft and other probes bound on one-way trips into interstellar space

New Horizons is about to wake up and study the Kuiper Belt, the universe and even Uranus and Neptune. But a new target to visit could trump them all

Nuclear fusion has broad implications, fueling hopes of clean, limitless energy and the long-held dream of future rockets that are driven by nuclear propulsion.

Scientist Ralph McNutt, Jr. is lobbying NASA to approve plans for a $3.1 billion Interstellar Probe that could launch in 2036 if it can escape the yoke of Earth's gravity — not to mention its wary accountants.

Launching an interstellar probe sounds exceedingly lofty, ambitious, and tough to do. But theres no need to wait for new technology, say advocates.

NASA's deep space Voyager probes will soon be deactivated. Here's why the space agency wants to shut them down.

Voyager 1 and Voyager 2 have traveled deeper into space than any other manmade object, making them the most distant cameras in the universe.

Both Voyagers launched from Cape Canaveral in Florida in 1977 - with Voyager 2 departing a month earlier than 1 - and were designed to last five years to study Jupiter and Saturn.

The Voyager probes massively exceeded the scope of their mission, but are running low on power after 45 years in space.
