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

For reference, Pluto’s average distance from the Sun is about 40 AU, so 2023 KQ14 is quite distant. At 23.4 billion miles (37 ...

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 ...

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 ...

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

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 probe operates beyond the heliosphere — the sun’s bubble of magnetic fields and particles that extends well beyond Pluto’s orbit — where its instruments directly sample interstellar space.

On Jan. 19, 2006, NASA launched the New Horizons probe which would provide never-before-seen images of the dwarf planet, its moons and other objects.

Fusion has long been the propulsion end-goal for interplanetary travel, and a U.K.-based company thinks on its way to achieving that dream.

The propulsion system must operate using low power (sub-kilowatt) and have high-propellant throughput (i.e., the capability to use a high total mass of propellant over its lifetime) to enable the ...
