NASA ISS On-Orbit Status 3 June 2015 - 50 Years of Spacewalks

NASA Astronaut Ed White made history on June 3, 1965, when he floated out of the hatch of his Gemini 4 capsule into the void of space. The first American "spacewalk" - or Extravehicular Activity (EVA) - lasted 23 minutes, not nearly long enough for White. He later said the spacewalk was the most comfortable part of the mission, and said the order to end it was the "saddest moment" of his life. Credit: NASA.

The six-member Expedition 43 crew conducted a variety of advanced microgravity science and performed spacesuit maintenance. U.S. astronauts Terry Virts and Scott Kelly also commemorated 50 years of operations in Houston's Mission Control Center.

The orbital lab's inhabitants explored a complex set of subjects in space including physics, biology and crew health. Flight Engineer Gennady Padalka studied plasma crystals which could benefit future spacecraft design. Italian astronaut Samantha Cristoforetti continued her work with the Rodent Research experiment that could potentially lead to new drugs to treat diseases on Earth.

One-Year crew member Mikhail Kornienko was back at work on the Fluid Shifts study partnering with Kelly and Padalka. The trio took measurements as part of an investigation to better understand how microgravity impacts fluid pressure in the head, changes in vision and eye structures.

On June 3, 1965, Mission Control Center in Houston began operations when Gemini IV lifted off for a four-day mission with astronauts James McDivitt and Ed White. America's first spacewalk also took place during that mission when White floated out of the spacecraft attached to a 25-foot umbilical line and tether.

On-Orbit Status Report

Fluid Shifts: Fluid Shifts operations continued today in the Russian Service Module (SM). Kelly donned the Lower Body Negative Pressure (LBNP/Chibis) device while Kornienko, with ground support in Moscow, assisted with medical monitoring. While Kelly was subjected to the negative pressure (pulling the fluid toward the feet), Padalka, with remote guidance in Houston, performed measurements with Distortion Product Otoacoustic Emissions (DPOAE), Optical Coherence Tomography (OCT), and Tonometry measurements. Fluid Shifts is a joint NASA-Russian experiment that investigates the causes for severe and lasting physical changes to astronaut's eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Haptics-2: Virts completed an On-Board Training (OBT) session and loaded the Haptics-2 software updates from Haptics-1 to Haptics-2. He then executed protocol one of two protocols. Haptics-2 is a technology demonstration experiment to validate for the first time a bilateral control interaction to take place between space and ground. Haptics-2 will compare the performance achievable through two different communication links: an IP forward link through Tracking and Data Relay Satellite System (TDRSS) with substantial amount of time-delay and high bandwidth and, (B) a direct S-band link through the KONTUR-2 system which has a short time-delay and reduced bandwidth. Haptics-2 consists of 2 independent experiment protocols aimed at quantifying the performance characteristics of the two different communication channels between space and ground (pre-test) and aimed at demonstrating for the first time real bilateral teleoperation with force-feedback to take place between space and ground through both communication links.

Wearable Monitoring: Prior to sleep, Cristoforetti set up hardware and donned the Wearable Monitoring Vest for data acquisition during sleep. This is the final of six planned sessions. The experiment validates a new cloth vest that monitors astronaut heart rates and breathing patterns during sleep. It also collects data to investigate whether changes in heart activity are related to astronauts' poor sleep quality. Current technology cannot check astronauts' heart activity while they sleep because the test wakes them. The Wearable Monitor is a lightweight vest with silver wires and sensors embedded into the fabric, making it more comfortable to wear.

Extravehicular Mobility Unit (EMU) 3010 Fan Pump Separator (FPS) Remove & Replace (R&R): Virts and Cristoforetti completed Part 1 of 2 to R&R the failed FPS in EMU 3010. They set up the Airlock, retrieved and assembled the necessary equipment and prepared the EMU for the removal tomorrow. On Friday, the crew will pack the removed FPS for return on 41 Soyuz (41S).
