STS078-398-032 (20 June - 7 July 1996) --- Astronaut Susan J. Helms, payload commander, measures the distance between Jean-Jacques Favier’s head and the luminous torque, used for the Canal and Otolith Interaction Study (COIS) on the Life and Microgravity Spacelab (LMS-1) mission. Favier, representing the French Space Agency (CNES), is one of two international payload specialists on the almost-17-day flight. This view shows the Voluntary Head Movement (VHM) segment of the experiment. The VHM is meant to characterize how the coordination of head and eye movement changes as a result of spaceflight. Since most vestibular functions are influenced by gravity, the COIS experiment is meant to measure response differences in microgravity.

S83-35768 (18-24 June 1983) --- Astronaut Sally K. Ride, mission specialist for STS-7, uses a screw driver in order to clean out an air filtering system in the mid-deck of the Earth-orbiting Space Shuttle Challenger. Dr. Ride's constant wear garment bears some extras -- a cartoon of 35 busy astronauts around a Space Shuttle and the acronym TFNG, below which is written, "We deliver!" TFNG stands for thirty-five new guys, referring to the 1978 class of astronaut candidates (ASCAN) from which Dr. Ride and three of her crew members hail. The tiny two-word declarative in white lettering refers to the successful deployment of two communications satellites. This photograph was made with a 35mm camera.

STS042-06-031 (30 Jan 1992) - - - STS-42 Payload Specialist Roberta L. Bondar gets into the Microgravity Vestibular Investigations (MVI) rotator chair to begin an experiment. The chair is mounted in the center aisle of the International Microgravity Laboratory 1 (IML-1) Spacelab (SL) module. Just above Bondar's head is the helmet assembly which is outfitted with accelerometers to measure head movements and visors that fit over each eye independently to provide visual stimuli. The chair system has three movement patterns: "sinusoidal" or traveling predictably back and forth over the same distance at a constant speed; "pseudorandom" or moving back and forth over varying distances; and "stepped" or varying speeds beginning and stopping suddenly.

Payload specialist Millie Hughes-Fulford, lower left, assists with the test.

A prominence rose up above the sun, sent an arch of plasma to link up magnetically with an active region over a one-day period (Jan, 9-10, 2017). Then the flow of plasma seemed to largely change direction and head back where it came from. Finally, amidst the confused patterns of movement, it dissipated and fell away. Prominences are cooler clouds of charged particles tenuously tethered to the sun by magnetic forces. Images were taken in a wavelength of extreme ultraviolet light.

KENNEDY SPACE CENTER, FLA. -- In the Spacecraft Assembly and Encapsulation Facility -2 (SAEF-2), the Mars Climate Orbiter is in place for its spin test. Targeted for launch aboard a Delta II rocket on Dec. 10, 1998, the orbiter is heading for Mars where it will primarily support its companion Mars Polar Lander spacecraft, which is planned for launch on Jan. 3, 1999.

Mechanic Howard Wine inspects the setup of a spin isolator in Cell 2 of the Propulsion Systems Laboratory at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Photographer Al Jecko filmed the proceedings. This test was unique in that the chamber’s altitude system was used, but not its inlet air flow. The test was in preparation for an upcoming launch of modified liquid hydrogen propellant tank on a sounding rocket. This Weightlessness Analysis Sounding Probe (WASP) was part of Lewis investigation into methods for controlling partially filled liquid hydrogen fuel tanks during flight. Second-stage rockets, the Centaur in particular, were designed to stop their engines and coast, then restart them when needed. During this coast period, the propellant often shifted inside the tank. This movement could throw the rocket off course or result in the sloshing of fuel away from the fuel pump. Wine was one of only three journeymen mechanics at Lewis when he was hired in January 1954. He spent his first decade in the Propulsion Systems Laboratory and was soon named a section head. Wine went on to serve as Assistant Division Chief and later served as an assistant to the director. Jecko joined the center in 1947 as a photographer and artist. He studied at the Cleveland School or Art and was known for his cartoon drawing. He worked at the center for 26 years.

In this photograph, astronauts Owen Garriott on the body restriant system and Byron Lichtenberg prepare for a Vestibular Experiment during the Spacelab-1 mission. The Vestibular Experiments in Space were the study of the interaction among the otoliths, semicircular canals, vision, and spinal reflexes in humans. The main objective was to determine how the body, which receives redundant information for several sensory sources, interprets this information in microgravity. Another objective was to record and characterize the symptoms of space sickness experienced by crewmembers. The body restraint system was a rotating chair with a harness to hold the test subject in place. The crewmember wore an accelerometer and electrodes to record head motion and horizontal and vertical eye movement as the body rotated. The first Spacelab mission, Spacelab-1, sponsored jointly and shared equally by NASA and the European Space Agency, was a multidisciplinary mission; that is, investigations were performed in several different fields of scientific research. The overall goal of the mission was to verify Spacelab performance through a variety of scientific experiments. The Spacelab-1 was launched aboard the Space Shuttle Orbiter Columbia for the STS-9 mission on November 28, 1983. The Marshall Space Flight Center had management responsibilities for the mission.

KENNEDY SPACE CENTER, FLA. -- A Boeing Delta II expendable launch vehicle lifts off with NASA's Mars Climate Orbiter at 1:45:51 p.m. EST, on Dec. 11, 1998, from Launch Complex 17A, Cape Canaveral Air Station. The launch was delayed one day when personnel detected a battery-related software problem in the spacecraft. The problem was corrected and the launch was rescheduled for the next day. The first of a pair of spacecraft to be launched in the Mars Surveyor '98 Project, the orbiter is heading for Mars where it will first provide support to its companion Mars Polar Lander spacecraft, which is planned for launch on Jan. 3, 1999. The orbiter's instruments will then monitor the Martian atmosphere and image the planet's surface on a daily basis for one Martian year (1.8 Earth years). It will observe the appearance and movement of atmospheric dust and water vapor, as well as characterize seasonal changes on the surface. The detailed images of the surface features will provide important clues to the planet's early climate history and give scientists more information about possible liquid water reserves beneath the surface

KENNEDY SPACE CENTER, FLA. -- In the Spacecraft Assembly and Encapsulation Facility -2 (SAEF-2), the Mars Climate Orbiter (top) is lowered toward the third stage of the Boeing Delta II launch vehicle below it, to which it will be attached. The third stage is a solid-propellant Thiokol Star 48B booster, the same final stage used in the 1996 launch of Mars Global Surveyor. Targeted for launch on Dec. 10, 1998, the orbiter is heading for Mars where it will primarily support its companion Mars Polar Lander spacecraft, which is planned for launch on Jan. 3, 1999. The orbiter's instruments will monitor the Martian atmosphere and image the planet's surface on a daily basis for 687 Earth days. It will observe the appearance and movement of atmospheric dust and water vapor, as well as characterize seasonal changes on the surface.
