Is There Life on Mars?

To get the answer, we have to know what to look for and where to go on the planet for evidence of past life. With the Perseverance rover set to land on Mars on February 18, we are finally in a position to know.

Lessons from Apollo 14

The Apollo program should be remembered as much for landing the first humans on the Moon as it is for countless demonstrations of problem solving and ingenuity, of continual fine-tuning and honing of expertise, which enabled NASA to set even more ambitious goals with each successive mission.

Small Steps and Giant Leaps in the Apollo Lunar Landings

The 50th anniversary of the Apollo 14 mission, which included the longest moonwalk without a rover, is a good time to show how traverses away from the lunar landers progressed from one mission to the next.

Driving Mars Exploration: How the Perseverance Rover Will Pave a Path into the Future

It’s been nearly 60 years since the first spacecraft were sent to Mars, and it’s inspiring to reflect on the progress that has been made since then. If all goes according to plan, the landing of the Mars 2020 Perseverance rover will mark the start of NASA’s ninth surface mission on the Red Planet.

Six Ways to Celebrate Perseverance This February

Be a part of NASA's Perseverance rover landing this February with these six ways to celebrate the mission to Mars.

70 Years Ago: F-86s and MiGs over Korea

On December 17, 1950, the first known aerial combat between swept-wing jet fighters took place in the skies over Korea. The Russian-built Mikoyan-Gurevich MiG-15 had been recently introduced and its speed and maneuverability caused trouble for the United States and in response, the North American F-86 Sabre was rushed to Korea. Ward Hitt, Jr., a member of the 4th Fighter Interceptor Group, chronicled the early days of the F-86 in combat in a detailed scrapbook.

George Robert Carruthers: Astronautical Engineer and Astronomer

Astronautical engineer and astronomer George Robert Carruthers, a name well-known and dearly regarded in the space science community, and a good friend of the National Air and Space Museum, passed away on Saturday, December 26 after a long illness.

Two prominent lobate thrust fault scarps on Mercury, Discovery Rupes and Beagles Rupes, imaged by Mercury Dual Imaging System (MDIS) on the MESSENGER spacecraft. Discovery Rupes (left), named for the ship HMS Discovery, shown here in a MDIS high-incidence angle image mosaic, was first imaged by Mariner 10 in the mid-1970’s. Beagle Rupes (right), a bow-shaped fault scarp, was initial imaged during MESSENGER’s first flyby.

Mercury, The Not So Shrunken Planet

Based on my research, which include image composites of two flyby views of Mercury from the MESSENGER spacecraft, I conclude that Mercury has not cooled and shrunken as much as previously thought.
