Orion Splashes Down April 10, Ending First Crewed Lunar Mission Since Apollo 17
The Orion capsule carrying the Artemis 2 crew splashed down in the Pacific Ocean on April 10, completing the first human mission beyond Earth orbit since December 1972. The four-person crew — Reid Wiseman, Victor Glover, Christina Koch, and CSA astronaut Jeremy Hansen — flew a free-return trajectory around the Moon before returning to Earth.
The mission sets the operational baseline for Artemis 3, which is planned to include an actual lunar landing. No crew vehicle had carried humans to lunar distance in over half a century, making this mission a direct data point for life support, navigation, and reentry system performance at that range.

Falcon 9 Delivers Cygnus CRS NG-24 to ISS on April 11
Northrop Grumman’s Cygnus CRS NG-24 cargo spacecraft launched aboard a SpaceX Falcon 9 on April 11, bound for the International Space Station. Northrop Grumman has no active expendable rocket of its own capable of this mission after retiring Antares — making SpaceX its launch provider for ISS resupply.
This continues a situation where Northrop Grumman, a primary ISS cargo contractor, relies entirely on a competitor for access to orbit. Cygnus is a resupply spacecraft that berthed via the ISS robotic arm rather than autonomous docking.

Artemis 2 Crew Reflects on Mission After Return to Earth
The Artemis 2 astronauts have begun post-mission debriefs and public engagements following splashdown. The crew described the lunar flyby as a deeply disorienting experience of scale — seeing Earth as a small object against deep space for the first time from crewed distance.
From a mission architecture standpoint, the crew’s firsthand accounts will feed directly into crew training refinements and human factors data for Artemis 3 planning.

NASA Outlines Artemis 3 and Subsequent Lunar Mission Plans
With Artemis 2 complete, NASA has laid out its forward schedule. Artemis 3 is planned to land crew near the lunar south pole using a SpaceX Human Landing System derived from Starship. Subsequent missions are expected to deploy Gateway lunar orbit infrastructure and expand surface stay durations.
The south pole target zone is driven by suspected water ice in permanently shadowed craters — a resource with direct implications for long-duration surface operations and propellant production.

Moog Systems Supported Crew Safety Across Artemis 2 Mission
Moog Inc. supplied precision fluid and motion control hardware used in Orion’s launch abort system and other safety-critical subsystems during Artemis 2. The East Aurora, NY-based company builds components that activate under abort scenarios and during reentry events — hardware that never needs to work until it absolutely has to.

CRS NG-24 Launch Detail: Cygnus Follows NG-23 Reentry by Weeks
Northrop Grumman’s previous Cygnus, the S.S. William McCool on CRS NG-23, completed its ISS mission shortly before NG-24’s April 11 launch. Cygnus vehicles are expendable — they reenter destructively after departure from the ISS rather than returning cargo to the surface.
Tracking the NG-24 Cygnus during its approach and berthing phase is possible via KeepTrack using its current NORAD catalog entry once orbital elements are published post-launch.

Satellite of the Day
YAOGAN-31 02C
The YAOGAN-31 02C is a Chinese Earth observation satellite launched on January 29, 2021, from the Jiuquan Satellite Launch Center aboard a Chang Zheng 4C rocket. Part of China’s Yaogan (Remote Sensing) program, this satellite is operated by ZLZB and manufactured by DFHZ. At 500 kilograms, it’s a compact imaging platform equipped with the Jianbing-8 payload, designed to collect high-resolution Earth observation data for civilian and military applications. The satellite features a straightforward box-and-panel design with two deployable solar arrays for power generation.
Operating in a sun-synchronous-like orbit inclined at 63.4°, YAOGAN-31 02C provides persistent imaging capabilities over mid-latitude regions. The Yaogan program has become central to China’s space domain awareness and resource monitoring initiatives, with this particular satellite joining a constellation of similar platforms. Its relatively compact design and mid-inclination orbit make it well-suited for regional monitoring tasks, from disaster assessment to infrastructure mapping.
