The Soyuz spacecraft undocked from the International Space Station at 9:53 p.m. EDT, carrying three people back to Earth. NASA Television will air live coverage beginning at 12 a.m. Friday, April 17, for the deorbit burn at 12:22 a.m. and the spacecraft's parachute-assisted landing.

NASA astronauts Andrew Morgan and Jessica Meir and Oleg Skripochka are expected to land in their Soyuz MS-15 spacecraft at 1:16 a.m. on the steppe of Kazakhstan southeast of the remote town of Dzhezkazgan (11:16 a.m. Kazakhstan time).

Among the research experiments to which the Expedition 62 crew contributed during their mission was the Droplet Formation Study, which evaluates water droplet formation, water flow and, indirectly, the perceived pressure of current shower head technology as compared to the industry-standard use of jet nozzles. The study examines droplet size and speed and how they affect the feeling of increased pressure for the end user. Another experiment to which the crew contributed was Mochii, a miniature scanning electron microscope used to conduct real-time, on-site imaging and composition measurements of particles. Analysis of small and microscopic particles is a critical need for human space exploration beyond low-Earth orbit when samples cannot be returned to Earth immediately for analysis.

On-Orbit Status Report

Functional Immune: The crew gathered blood samples in support of the Functional Immune investigation. The Functional Immune Alterations, Latent Herpesvirus Reactivation, Physiological Stress and Clinical Incidence Onboard the International Space Station (Functional Immune) investigation analyzes blood and saliva samples to determine the changes taking place in crew members' immune systems during flight.

ISS Experience: The crew set up the appropriate ISS Experience hardware and captured their preparation for the 61-Soyuz crew departure. The ISS Experience creates a virtual reality film documenting daily life aboard the ISS. The 8 to 10 minute videos created from footage taken during the six-month investigation cover different aspects of crew life, execution of science aboard the station, and the international partnerships involved. The ISS Experience uses a Z-CAM V1 Pro Cinematic Virtual Reality (VR) 360-degree camera with nine 190° fisheye lenses.

JEM AirLock (JEMAL): In preparation for the next investigation to use the JEMAL, the crew extended the slide table, removed the JEM ORU Transfer Interface (JOTI) hardware (which was used by a previous investigation), retracted the slide table and closed the airlock. The JEM airlock allows hardware to be passed from the pressurized volume in the ISS to the unpressurized Exposed Facility area, where the hardware can then be manipulated robotically.

Systems

61S Crew Return Preparation: ISS crew prepared for the 61S return by completing the final touches on packing the Soyuz spacecraft for departure. Later today, Oleg Skripochka, Jessica Meir and Drew Morgan will return to Earth Thursday night/Friday morning on 61S. Undocking is scheduled for 8:53 pm CT Thursday evening with the landing in Kazakhstan scheduled early Friday morning at 12:17 am CT.
