What are competed planetary missions?
A critical part of a balanced exploration program, competed missions are scientist-led projects that cost less and occur more frequently than large, flagship-class missions.
What to look forward to in space in 2024
A total solar eclipse and the launch of Europa Clipper are on our list of cosmic events to get excited about this year.
The best pictures of Mars from space
Spacecraft have been taking pictures of Mars from space since 1965. Here are some of our favorites.
Lucy’s flyby of Dinkinesh: Everything you need to know
On Nov. 1, 2023, NASA’s Lucy spacecraft flew past Dinkinesh, a small asteroid in the main belt, and discovered a binary pair of moonlets in orbit around the asteroid.
Psyche mission successfully launches
The spacecraft has begun its six-year journey to the same-name metal world.
The Psyche launch and its journey to a metal world: What to expect
The Psyche spacecraft is scheduled to blast off on a SpaceX Falcon Heavy rocket on Oct. 13.
The boy who named Bennu is now an aspiring astronaut
The Planetary Society spoke to Mike Puzio, who won our "Name that asteroid!" contest back in 2013.
OSIRIS-REx returns sample from asteroid Bennu to Earth
The sample capsule parachuted to a landing at the Department of Defense’s Utah Test and Training Range southwest of Salt Lake City.
Cometary sights and sounds
Discover what causes a comet’s color and what it might be like to listen to one whiz by.
OSIRIS-REx sample return: What to expect
The spacecraft will drop off its precious samples of asteroid Bennu on Sept. 24, 2023.
Day and night, it’s all about starlight
This week in space: Mars days almost match up with ours, and light and molecules are created by distant stars.
Why did we need OSIRIS-REx?
How OSIRIS-REx’s samples build upon our knowledge of asteroids and the early Solar System.
Asteroid samples from another world
The OSIRIS-REx team explains the journey home.
The scientific truth is out there
The real science of aliens, the policy implications of ET, and new views of worlds beyond our own.
Moonshadow, Moonshadow
The Moon casts shadows on itself and on Earth, environmental concerns overshadow a test launch’s success, and exoplanets are awesome (beyond a shadow of a doubt).
What happened with Psyche?
When the Psyche mission missed its launch date in 2022, it caused a ripple-effect of delays and budget woes for other JPL-led missions. Dr. Laurie Leshin, JPL's new director, shares her insights into the unique challenges facing her team and what she's doing to change JPL for the better.
Asteroids worth getting psyched about
New discoveries from Ryugu, material heading our way from Bennu, and anticipation for a mission to Psyche.
Spectacularly crepuscular!
Curiosity captures crepuscular rays on Mars, a new member community launches, and solar sailing takes exploration into the future.
More worlds, anyone?
The more we search, the more we find. From exoplanets to moons to asteroids, the list of worlds just keeps growing.
By Jove! (Literally)
Jupiter’s moons have always been exciting to explore, and a new era of Jovian moon research is about to begin.
