August 17, 2018 - Getting to within striking distance of the moon is challenging enough, but if the ultimate objective is to achieve meaningful lunar exploration, getting there is only half the battle.

As the main- and upper-stage engine supplier for NASA’s heavy-lift Space Launch System (SLS), Aerojet Rocketdyne plays a prominent role in the first half of the equation. But the company also is integral to the second half: logistics in cislunar space and landing hardware on the lunar surface.

June 15, 2018 - Getting to Mars takes propulsion systems of all shapes and sizes, but one thing they nearly all have in common is Aerojet Rocketdyne.

Beginning more than four decades ago with the Viking 1 and 2 orbiter/lander missions, NASA has relied on Aerojet Rocketdyne to propel its Mars missions – from launch, to landing and everything in between. These missions have ranged in scale from the 25-pound Mars Pathfinder rover, to the Mars Science Laboratory’s 1-ton Curiosity rover.
