Artemis II Wet Dress Rehearsal: Taking Things Into the Home Stretch

In the pre-rocket-launch preparation ritual known as the wet dress rehearsal (WDR), the Artemis II launch team runs through nearly every step of the countdown sequence just as they would on launch day.

L3Harris to Provide Advanced Technology for Korean Geostationary Weather Satellite

L3Harris Technologies has received a contract from LIG Nex1 to provide the next-generation imaging payload for the Korea Meteorological Administration’s (KMA) geostationary weather satellite, which will improve the accuracy and timeliness of forecasting for the Korean Peninsula.

For L3Harris, the Action Starts Six Seconds Before Artemis II Lifts Off

The RS-25 engines ensure a safe and successful start to NASA’s historic Artemis II crewed mission to the Moon.
