The launch of Crew-2, the 2nd flight of this particular Crew Dragon, went off without a hitch Friday morning, after being postponed due to weather.

On April 17, 2021, the New Horizons spacecraft passed 50 astronomical units - 50 times Earth's distance from the sun - while speeding toward interstellar space. It also captured an image of another earthly spacecraft, even farther out.

The Mars helicopter - named Ingenuity - successfully flew in the thin air of Mars early in the day on Monday, April 19. Images here.

Northrop Grumman said last week that its Mission Extension Vehicle 2 - a robot spacecraft designed to help prolong the life of satellites in space - successfully docked to a commercial communications satellite. "We are now the only provider of life extension services for satellites," a company spokesperson said.

During its final flyby this month, the spacecraft OSIRIS-REx took an image of the location where it collected a sample from asteroid Bennu's surface. It'll return to Earth 2 years from now, providing scientists with clues to the creation of our solar system.

Jupiter's large size and cool core make it an excellent target in the search for dark matter. A team of scientists is analyzing gamma-ray data from the Fermi Telescope looking for signs of the elusive substance.

The unexpected discovery of yellowballs by citizen scientists - in 2011 and 2012 - is shaking up astronomers' ideas about how stars and star clusters form. It's giving scientists a new window into the birth and evolution of young stars.

NASA has given the name Rafael Navarro Mountain to a hill in Gale Crater on Mars, where the Curiosity rover has been exploring since 2012. Navarro, a mission scientist, died in January 2021 from Covid-19.

The chemical fingerprint of exoplanet HD 209458b's atmosphere reveals as many as 6 molecules and that it has migrated inwards from its birthplace much farther out in its star system.

A new analysis of data from the 1978 Pioneer Venus mission, by researchers at Cal Poly Pomona, finds evidence not only for phosphine, but also possible chemical disequilibrium in Venus' atmosphere, an additional possible sign of biological activity.
