Peregrine will likely burn up in Earth’s atmosphere, the moon lander’s builder has said

What lessons does the loss of the Titan submersible have for preventing spaceflight disasters?

NASA’s Mars Sample Return program is the agency’s highest priority in planetary science, but projected multibillion-dollar overruns have some calling the plan a “dumpster fire”

Astrobotic’s Peregrine lander was meant to be the first commercial spacecraft to operate on the surface of the moon. Instead it may not reach lunar orbit at all

A new analysis finds that images from Voyager 2's close encounter with Neptune show the planet as being far too blue

Unique studies of gravity waves, atmospheric holes and dazzling coronal displays will accompany April’s total solar eclipse across the U.S., Mexico and Canada

Aditya-L1 will join more than four active spacecraft at the first Lagrange point, a nearly stable region in the gravitational field between Earth and the sun

This year’s most interesting space images include infrared views of galactic “bones,” an asteroid’s double moon, Jupiter’s giant polar vortex, and more

Here’s the best, most inspiring and coolest science we encountered this year

The first vehicles to fly under NASA’s new lunar delivery initiative will aim to be the first commercial spacecraft to land softly on another celestial body

Mars Sample Return has always been an expensive, high-risk, high-reward project. But now, with realization of the mission’s actual cost and expanding timeline, Congress must commit to fully supporting the effort or risk tanking the rest of NASA’s planetary science program

Astronomers are moving ahead in planning NASA’s Habitable Worlds Observatory, a telescope designed to answer the ultimate question: Are we alone in the universe?
