JOHNSON SPACE CENTER, HOUSTON, TEXAS -- (ISS006-S-002) (From left) Astronauts Donald R. Pettit, Expedition Six flight engineer, and Kenneth D. Bowersox, mission commander; and cosmonaut Nikolai M. Budarin, flight engineer, attired in training versions of the Shuttle launch and entry suit, pause from their training schedule for a crew portrait. The three will be launched to the International Space Station (ISS) in late autumn of this year aboard the Space Shuttle Endeavour. Budarin represents Rosaviakosmos.

Expedition Seven photographed the Soyez TMA-1 Capsule through a window of the International Space Station (ISS) as it departed for Earth. Aboard were Expedition Six crew members, astronauts Kerneth D. Bowersox and Donald R. Pettit, and cosmonaut Nikolai M. Budarin. Expedition Six served a 5 and 1/2 month stay aboard the ISS, the longest stay to date.

In this International Space Station (ISS) onboard photo, Expedition Six Science Officer Donald R. Pettit works to set up the Pulmonary Function in Flight (PuFF) experiment hardware in the Destiny Laboratory. Expedition Six is the fourth and final crew to perform the PuFF experiment. The PuFF experiment was developed to better understand what effects long term exposure to microgravity may have on the lungs. The focus is on measuring changes in the everness of gas exchange in the lungs, and on detecting changes in respiratory muscle strength. It allows astronauts to measure blood flow through the lungs, the ability of the lung to take up oxygen, and lung volumes. Each PuFF session includes five lung function tests, which involve breathing only cabin air. For each planned extravehicular (EVA) activity, a crew member performs a PuFF test within one week prior to the EVA. Following the EVA, those crew members perform another test to document the effect of exposure of the lungs to the low-pressure environment of the space suits. This experiment utilizes the Gas Analyzer System for Metabolic Analysis Physiology, or GASMAP, located in the Human Research Facility (HRF), along with a variety of other Puff equipment including a manual breathing valve, flow meter, pressure-flow module, pressure and volume calibration syringes, and disposable mouth pieces.

Astronaut Donald R. Pettit, Expedition Six NASA ISS science officer, photographed this view of a surface tension demonstration using water that is held in place by a metal loop. The experiment took place in the Destiny laboratory on the International Space Station (ISS). The Expedition Six crew was delivered to the station via the Space Shuttle Orbiter Endeavor STS-113 mission which was launched on November 23, 2002.

International Space Station (ISS) crew members were able to document a rare occurrence. The dark area near the center of the frame is actually a shadow cast by the moon during the total solar eclipse of December 4, 2002. The shadow obscures an area of cloud cover. The Station, with three Expedition Six crew members aboard, was over the Indian Ocean at the time of the eclipse.

This is a view of the Emi Koussi Caldera captured by the Expedition Six Crew Observation (CEO) experiment aboard the International Space Station (ISS). Rising 2.3 km above the surrounding sandstone plains, Emi Koussi is a 6.5 km wide volcano located at the south end of the Tibesti Mountains in the central Sahara desert. The volcano is one of several in the Tibesti massif and has been used as a close analog to the famous Martian volcano Elysium Mons. Major charnels can be seen on volcanoes on both planets that indicate low points in caldera rims where lava spilled out of the pre-collapsed craters.

ISS006-E-33736 (25 February 2003) --- The boot of Italy crosses the image in this southwest-looking view taken by an Expedition Six crewmember onboard the International Space Station (ISS). The spine of Italy is highlighted with snow and the largely cloud-covered Mediterranean Sea is at the top. The Adriatic Sea transverses most of the bottom of the image and Sicily appears top left beyond the toe of the boot. The heel lies out of the left side of the image. Corsica and Sardinia appear right of center partly under cloud. The floor of the Po River valley, lower right, is obscured by haze. Experience gained from similar haze events, in which atmospheric pressure, humidity and visibility and atmospheric chemistry were known, suggests that the haze as industrial smog. Industrial haze from the urban region of the central and upper Po valley accumulates to visible concentrations under conditions of high atmospheric pressure and the surrounding mountains prevent easy dispersal. This view illustrates the markedly different color and texture of cloud versus industrial aerosol haze.

ISS006-E-22132 (January 2003) --- A portion of the Society Islands was captured with a digital still camera by one of the Expedition Six crewmembers on the International Space Station (ISS). The evolution of fringing reefs to atolls was captured in this one frame. As with the Hawaiian Islands, these volcanic hot spot islands become progressively older to the northwest. As these islands move away from their magma sources they erode and subside. The two large islands, Raiatea and Tahaa, share a single fringing reef. The next island to the northwest, Bora-Bora, consists of a highly eroded volcanic remnant with fringing reef. The last island, Tupai, has become an atoll with the central portion below sea level.

ISS006-E-39299 (15 March 2003) --- A close up view of sugar crystals in a water bubble within a 50-millimeter (mm) metal loop was photographed by an Expedition Six crewmember. The experiment took place in the Destiny laboratory on the International Space Station (ISS).

JSC2002-E-36202 (27 August 2002) --- Astronaut Donald R. Pettit, Expedition Six flight engineer, participates in an Extravehicular Mobility Unit (EMU) spacesuit fit check in a Space Station Airlock Test Article (SSATA) in the Crew Systems Laboratory at the Johnson Space Center (JSC). Zebulon L. Scoville assisted Pettit.

ISS006-E-05004 (28 November 2002) --- Astronaut Paul S. Lockhart (left), STS-113 pilot, looks over a procedures checklist as astronaut Donald R. Pettit, Expedition Six NASA ISS science officer, floats into the Quest Airlock on the International Space Station (ISS).

ISS006-E-45293 (21 March 2003) --- Cosmonaut Nikolai M. Budarin, Expedition Six flight engineer, uses a still camera to photograph the topography of a point on Earth from a window in the Zvezda Service Module on the International Space Station (ISS). Budarin represents Rosaviakosmos.

JSC2002-E-36194 (27 August 2002) --- Astronaut Donald R. Pettit, Expedition Six flight engineer, participates in an Extravehicular Mobility Unit (EMU) spacesuit fit check in a Space Station Airlock Test Article (SSATA) in the Crew Systems Laboratory at the Johnson Space Center (JSC).

ISS006-E-39254 (14 March 2003) --- A view of sodium chloride inserted onto blueberry jelly within a 50-millimeter (mm) metal loop was photographed by an Expedition Six crewmember. The experiment took place in the Destiny laboratory on the International Space Station (ISS).

ISS006-E-12694 (16 December 2002) --- Astronaut Kenneth D. Bowersox, Expedition Six mission commander, uses a still camera to photograph the topography of a point on Earth from the nadir window in the Destiny laboratory on the International Space Station (ISS).

ISS006-E-39258 (14 March 2003) --- A close up view of sodium chloride inserted onto blueberry jelly within a 50-millimeter (mm) metal loop was photographed by an Expedition Six crewmember. The experiment took place in the Destiny laboratory on the International Space Station (ISS).

ISS006-E-33073 (24 February 2003) --- Astronauts Kenneth D. Bowersox (right) and Donald R. Pettit, Expedition Six mission commander and NASA ISS science officer, respectively, participate in a scheduled extravehicular activity (EVA) development test objective (DTO) in the Quest Airlock on the International Space Station (ISS). The test demonstrated the ability of two crewmembers to safely get into the American Extravehicular Mobility Unit (EMU) spacesuit without the assistance of a third crewmember; that ability is a prerequisite to sending smaller crews to ISS while the space shuttle fleet remains grounded during the investigation of the Columbia accident. Bowersox and Pettit helped each other into their EMU spacesuits, donned jet backpacks called Simplified Aid for EVA Rescue (SAFER), set up the necessary equipment for a pre-breathe of oxygen to purge nitrogen from their bloodstreams, and then got out of the spacesuits.

ISS006-E-28028 (February 2003) --- The Southern Cross (left center), the Coal Sack Nebula (bottom left), and the Carina Nebula (upper right) are visible in this view photographed by astronaut Donald R. Pettit, Expedition Six NASA ISS science officer, on board the International Space Station (ISS). The Carina Nebula is a molecular cloud about 9000 light years from Earth where young stars are forming. The Coal Sack Nebula is an inky-black dust cloud about 2000 light years from Earth. Stars are probably condensing deep inside the Coal Sack, but their light has not yet broken through the cloud’s dense exterior. The Southern Cross, also known as The Crux, is a constellation familiar to southern hemisphere stargazers.
