Sedna will make its closest approach to the Sun in 2076, giving us a rare opportunity to visit the planetoid before it drifts ...

In the outer reaches of our solar system, far beyond the orbit of Pluto, lies Sedna, one of the most mysterious objects ever discovered. This reddish dwarf planet follows such an extreme orbit that it ...

Although reaching Proxima Centauri, which is over 4 light-years away, would still require travel times of several decades to centuries with current technology, nuclear-powered propulsion ...

It took over nine years for New Horizons to reach Pluto after blasting off atop an Atlas 5 rocket on Jan. 19, 2006. After ...

Improved technology might allow a probe to launch later than 2004 and forgo a Jupiter gravity assist. "The arrival time at Pluto would be a key factor, not a launch date," Weiler said. Bids for ...

A spacecraft near Mars would wait several minutes and missions at Pluto and beyond take few hours. Each astronomical unit is almost 93 million miles and it is the distance from the Earth to the Sun.

With ground testing scheduled for 2025 and an orbital demonstration planned for 2027, Sunbird could mark a bold leap forward in next-generation propulsion technology.

The propulsion system would shorten the probe’s travel time to Pluto and would enable it to explore other objects beyond Pluto after its mission there concludes.

How can fission-powered propulsion help advance deep space exploration, specifically to the outer planets like Jupiter, Saturn, Uranus, and Neptune? This is what a recent study presented at the ...
