NASA International Space Station On-Orbit Status 9 May 2016.

The SpaceX Dragon is being packed with critical science today and tomorrow before its release and splashdown on Wednesday. The crew is also reviewing Dragon departure procedures and training for its release from the grip of the Canadarm2 robotic arm.

Dragon is currently attached to the Harmony module. After it is uninstalled early Wednesday with the 57.7 foot Canadarm2, the Dragon will be released at 9:18 a.m. EDT for a splashdown in the Pacific Ocean at 2:55 p.m. NASA TV will broadcast the release and departure activities live, however the splashdown and recovery work will not be televised.

A pair of science freezers carrying experiment samples for analysis will be removed from the space station and returned to Earth inside Dragon. The commercial space freighter is returning a variety of science and gear for NASA.

The Russian cosmonauts are relaxing today in observance of Victory Day when Germany surrendered to the Soviet Union on May 9, 1945, ending World War II. The astronauts in the U.S. segment of the station continued science work, Dragon packing and robotics training for Wednesday's release activities.

On-Orbit Status Report

Sprint: The crew completed the exercise protocol and data collection for Sprint VO2. Sprint VO2 measures oxygen uptake, ventilatory threshold, and other physiological parameters. It evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in ISS crew members during long-duration missions.

Meteor Procedure Review: In preparation for upcoming activities later this week, the crew reviewed procedures for the software load and Meteor installation. Meteor will perform the first space-based observations of the chemical composition of meteors entering Earth's atmosphere. Meteors are relatively rare and are difficult to monitor from the ground because of the interference created by Earth's atmosphere. The Meteor investigation takes high-resolution video and images of the atmosphere and uses a software program to search for bright spots which can later be analyzed on the ground.

NanoRack Module 9: The crew completed the fifth NanoRack Module 9 experiment session by activating, deactivating, and shaking the mixture tubes to facilitate the experiment. Module-9 is a collection of student research projects utilizing the NanoRacks Mixsticks. Student teams from across the United States design their own experiments using flight approved fluids and materials.

Rodent Research 3 CASIS: Crewmembers inspected and restocked the habitats with water, and with Food Bars retrieved from the Minus Eighty Degree Laboratory Freezer for ISS (MELFI).

SpaceX (SpX)-8 Departure Preparation: In preparation for SpX-8 unberth next Wednesday, May 11, the following were completed today:
- Robotics On-Board Trainer (RoBOT) session to practice vehicle release including two release runs and self study.
- Commercial Off The Shelf (COTS) Ultra High Frequency (UHF) Communication Unit (CUCU) and Dragon Crew Command Panel (CCP) activation and checkout.
- POLAR transfer to Dragon.
- Double Cold Bag packing.

At this time, the weather looks favorable for splashdown Wednesday.

Pressurized Mating Adapter (PMA1)/Node 1 (N1) Intermodule Ventilation (IMV) Reconfiguration: Russian Segment and USOS split ventilation is still in effect. Over the weekend, the Lab Forward Starboard IMV fan was activated to address a ppCO2 delta between the Lab and N2. Today, the N3 Overhead Starboard IMV fan was deactivated to reduce the amount of air that is being pulled into the N1 overhead diffuser from PMA1. Airflow from N1 into N3 will be exchanged through the hatch only. The USOS ppCO2 24-hour average is 3.18 mmHg. Teams will continue monitoring CO2 at multiple locations throughout ISS.
