NASA's Artemis II mission successfully sent astronauts around the moon using Boeing's rocket. However, the Trump administration is now seeking cheaper alternatives from competitors like SpaceX for future lunar endeavors.

SpaceX launched a Falcon 9 rocket from Cape Canaveral on Saturday, sending over 11,000 pounds of supplies to the International Space Station.

The per-pound cost of carrying anything into outer space has fallen more than 90% since modern day rocketry’s inception. This relatively new degree of affordability is accelerating the development of satellites and other technologies that can make good use of it.

NASA's Space Launch System rocket for the Artemis moon mission is one of the largest ever. Here's how it compares to Starship, Saturn V and more.

A SpaceX Falcon 9 rocket launched a Northrop Grumman Cygnus XL cargo spacecraft to the ISS Saturday morning, April 11.

Artemis II mission will take 4 astronauts on a trip around the moon. The vehicle that will send them there? A massive NASA Space Launch System rocket.

Mars exploration is heating up. NASA eyes sample returns and crewed landings by the 2030s, but its current relay satellites — some decades past design life — struggle with data traffic from rovers, orbiters and future habitats.
