Over the course of the approximately 70‑minute activity, the crew guided Integrity through a series of controlled approach and retreat maneuvers using the detached ICPS (interim cryogenic propulsion stage) as a reference target. At the conclusion of the demo, Integrity executed a departure burn to safely back away from the ICPS. [b]CubeSats to Deploy[/b] Four small satellites, or CubeSats, also launched to high Earth orbit in the Orion stage adapter of the SLS (Space Launch System). CubeSats are shoebox-sized payloads that have the potential to expand knowledge of the space environment. These experiments will be deployed after the adapter has separated from the spacecraft. The four CubeSats are: [list][]ATENEA, developed by the Argentina National Space Activities Commission, will investigate radiation shielding, orbital design optimization, and long-range communications. []Space Weather CubeSat-1, developed by the Saudi Space Agency, will measure various aspects of space weather, such as radiation, solar X-rays, solar energy particles, and magnetic fields. []TACHELES, developed by the German Aerospace Center, will demonstrate key in-space technologies, including electrical components for future lunar logistics vehicles and operations. []K-Rad Cube, developed by KASA (Korea AeroSpace Administration) will measure space radiation and its biological effect across the Van Allen radiation belts.[/list] [b]Perigee Raise Burn[/b] After a four-hour nap, the crew will be awakened at 7 a.m. EDT on Thursday (April 2) to prepare for a perigee raise burn. This burn will lift the lowest point of Orion's orbit around Earth. Together with the apogee raise burn completed earlier, these maneuvers shape Orion's initial orbit and prepare it for later trans-lunar operations. The crew will resume their sleep period around 9:40 a.m. EDT.</blockquote> <center><iframe width="400" height="225" src="https://www.youtube.com/embed/XAv9wTVDpcg?si=MMhVjm-bM_tRK_Cc" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></center>
