Ion propulsion company Accion Systems has raised $11 million in its latest funding round and has launches and contracts planned this year with NASA, the DoD and academic institutions.

As the 2010s come to a close, it's time to revisit how some of the biggest space science stories shaped the decade.

As the 2010s come to a close, it's time to revisit how some of the biggest space science stories shaped the decade.

From a world with three suns in its sky to lots of possibly habitable real estate, the past year has seen some incredible exoplanet discoveries. Here are 10 of the most memorable.

Ground and space telescope missions plan to further explore exoplanets discovered by NASA's TESS spacecraft.

When it comes to finding exoplanets, more computing power isn't always the answer.

Assuming that alien life will be similar to what evolved here on Earth could severely limit the potential for big discoveries, researchers said.

TESS team members recently provided insight and updates about the mission's first year of science operations.

Going to space is hard, but a panel of astronauts say communication, community and art can make it a little bit easier.

Space is going to ask more from us than brains and brawn.

Two proposed microsatellites could help NASA explore Venus and the moon.

The technological utopias of science fiction may still be centuries away, but building the culture of that future starts now.
