NASA restarts Moon rocket Wet Dress Rehearsal countdown
Spaceflightnow.com (4/12): As planned, NASA resumed the milestone Artemis I Wet Dress Rehearsal (WDR) at the agency’s Kennedy Space Center (KSC) on Tuesday. The two-day countdown simulation that began on April 1 was interrupted twice by difficulties with ground systems and finally a helium check valve in the Space Launch System’s (SLS) upper stage. The rehearsal that is to wrap up on Thursday is now focused on loading of liquid oxygen and hydrogen propellants in the SLS core stage and minimal propellant operations on the upper stage. Upon completion of the launch pad countdown simulation, the rocket will be returned to the Vehicle Assembly Building (VAB), while NASA experts assess the results of the countdown rehearsal and establish a launch date.

NASA photos show the Perseverance Mars rover and Tiny Ingenuity Helicopter from space
Space.com (4/12): The new images, snapped on March 31 by the HiRISE (High Resolution Imagine Experiment) camera aboard NASA’s Mars Reconnaissance Orbiter, show both the rover and helicopter together on the planet’s surface. The photos come just about 16 years after the camera delivered its first Mars photos. Perseverance can be seen sitting on the cracked surface of a large rock formation called “Máaz” the Navajo word for “Mars.” About 656 feet to the left of the rover, Ingenuity sits on the bedrock.
