Astronaut James S. Voss, mission specialist, handles the newly-delivered main boom of the Russian crane (Strela) to be connected to its operator post in 2000. During this 6-hour, 44-minute extravehicular activity, astronauts Voss and Jeffrey N. Williams also secured a United States-built crane that was installed on the station last year; replaced a faulty antenna for one of the station's communications systems; and installed several handrails and a camera cable on the station's exterior.

A panoramic view of a vast, sculpted area of gas and dust where thousands of stars are being born in the Doradus Nebula has been captured by NASA's Hubble Space Telescope. The mosaic picture shows that ultraviolet radiation and high-speed material unleashed by the stars in the cluster, called R136 (the large blue blob left of center), are weaving a tapestry of creation and destruction, triggering the collapse of looming gas and dust clouds and forming pillar-like structures that incubate newborn stars.

Middle school students across the country photographed the fires and smoke over southern Sumatra from a camera aboard the Space Shuttle Atlantis in September 1997. A joint effort between 23 of the 52 schools participating in this mission, the KidSat camera was used to image a 86 miles wide, 1,200 mile long strip that starts in the northwest, and follows the Pegunungan Barisan range across the equator to the southern tip of Sumatra.

Flying through the canyons and over the ridges of Valles Marineris, viewers can experience some of the thrills that gripped explorers who pushed into unknown regions on Earth. Buried in the rocks of this magnificent Martian canyon lies a history book of Mars that scientists have just begun to open. This still comes from "Flight Through Mariner Valley," an exciting video produced for NASA by the Jet Propulsion Laboratory. NASA/JPL/Arizona State University

Frames from a three dimensional visualization of Jupiter's equatorial region are seen here. The images used cover an area of about 21,100 by 6,800 miles near an equatorial "hotspot" similar to the site where the probe from NASA's Galileo spacecraft entered Jupiter's atmosphere on December 7th, 1995. These features are holes in the bright, reflective, equatorial cloud layer where warmer thermal emission from Jupiter's deep atmosphere can pass through. NASA/JPL
This full view of the International Space Station (ISS) was recorded by the STS-110 crewmembers on board the Space Shuttle Atlantis in 2002 following the undocking of the two spacecraft some 247 statute miles above the North Atlantic. NASA
This false color representation of Jupiter's Great Red Spot was taken through three different near-infrared filters of the Galileo imaging system and processed to reveal cloud top height. Images taken through Galileo's near-infrared filters record sunlight beyond the visible range that penetrates to different depths in Jupiter's atmosphere before being reflected by clouds. NASA
Astronauts John W. Young (r.), Apollo 16 commander, and Charles M. Duke Jr., lunar module pilot, prepare to begin a simulated traverse in a training area at the Kennedy Space Center in 1972. A training model of the Lunar Roving Vehicle is parked between the two crewmen; Young and Duke maneuver a training version of the LRV about a field simulated to represent the lunar surface. NASA
Seventy years ago, AP's Joe Rosenthal took the now iconic photo of US Marines raising the flag at Iwo Jima. The Christian Science Monitor reported why the tiny island played such a huge role in the war's Pacific theater.

This article originally ran in The Christian Science Monitor on Feb. 23, 1945, on the same day when Associated Press photographer Joe Rosenthal took the now iconic photo of US Marines raising the nation's flag on the island of Iwo Jima in the Pacific Ocean. The Monitor's Joseph C. Harsch explained at the time why Iwo Jima played such an important role in the US campaign in the Pacific during World War II.
