This is an artist's concept of the completely operational International Space Station being approached by an X-33 Reusable Launch Vehicle (RLV). The X-33 program was designed to pave the way to a full-scale, commercially developed RLV as the flagship technology demonstrator for technologies that would lower the cost of access to space. It is unpiloted, taking off vertically like a rocket, reaching an altitude of up to 60 miles and speeds between Mach 13 and 15, and landing horizontally like an airplane. The X-33 program was cancelled in 2001.

This is an artist's interpretation of a future launch complex for third generation propulsion reusable launch vehicles such as the X-33. The X-33 is a sub-scale technology demonstrator prototype of a Reusable Launch Vehicle (RLV), with a vertical take off / horizontal landing (lifting body) concept, which was manufactured and named as the Venture Star by Lockheed Martin. The X-33 program was cancelled in 2001.

KENNEDY SPACE CENTER, FLA. - Shrouded with a protective cover, half of the payload fairing for the STEREO spacecraft has been raised to a vertical position in front of the mobile service tower on Launch Pad 17-B at Cape Canaveral Air Force Station in Florida. The fairing will be lifted into the clean room in the tower and later installed around the spacecraft for protection during launch. The fairing is a molded structure that fits flush with the outside surface of the Delta II upper stage booster and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent. STEREO, which stands for Solar Terrestrial Relations Observatory, comprises two spacecraft. The STEREO mission is the first to take measurements of the sun and solar wind in 3-dimension. This new view will improve our understanding of space weather and its impact on the Earth. STEREO is expected to lift off aboard a Boeing Delta II rocket in August 2006.

KENNEDY SPACE CENTER, FLA. - In front of the mobile service tower on Launch Complex 41 at Cape Canaveral Air Force Station in Florida, the Lockheed Martin Atlas V Centaur stage is raised off the transporter. Once vertical, the Centaur, the second stage of the launch vehicle for the New Horizons spacecraft, will be lifted up the tower and mated with the waiting first stage, seen at left. New Horizons will make the first reconnaissance of Pluto and its moon, Charon - a "double planet" and the last planet in our solar system to be visited by spacecraft. As it approaches Pluto, the spacecraft will look for ultraviolet emission from Pluto's atmosphere and make the best global maps of Pluto and Charon in green, blue, red and a special wavelength that is sensitive to methane frost on the surface. It will also take spectral maps in the near infrared, telling the science team about Pluto's and Charon's surface compositions and locations and temperatures of these materials. When the spacecraft is closest to Pluto or its moon, it will take close-up pictures in both visible and near-infrared wavelengths. The mission will then visit one or more objects in the Kuiper Belt region beyond Neptune. New Horizons is scheduled to launch in January 2006, swing past Jupiter for a gravity boost and scientific studies in February or March 2007, and reach Pluto and Charon in July 2015.

CAPE CANAVERAL, Fla. – The Shuttle Carrier Aircraft transporting space shuttle Discovery flies over the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Air Force Station after taking off from Kennedy Space Center’s Shuttle Landing Facility at 7 a.m. EDT. The duo are heading south to fly over Brevard County’s beach communities, offering residents the opportunity to see the shuttle before it leaves the Space Coast for the last time. The aircraft, known as an SCA, is a Boeing 747 jet, originally manufactured for commercial use, which was modified by NASA to transport the shuttles between destinations on Earth. This SCA, designated NASA 905, is assigned to the remaining ferry missions, delivering the shuttles to their permanent public display sites. NASA 905 is scheduled to ferry Discovery to the Washington Dulles International Airport in Virginia on April 17, after which the shuttle will be placed on display in the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center. For more information on the SCA, visit http://www.nasa.gov/centers/dryden/news/FactSheets/FS-013-DFRC.html.

CAPE CANAVERAL, Fla. - Despite the incline, space shuttle Atlantis remains on a level plane as it rolls off Launch Pad 39A at NASA's Kennedy Space Center in Florida. First motion was at 6:48 a.m. EDT. The crawler-transporter underneath the mobile launcher platform maintains the level plane through a leveling system designed to keep the top of the space shuttle vehicle vertical. This system also provides the leveling operations required to negotiate the 5-percent ramp leading to the launch pads. Atlantis is rolling back to the Vehicle Assembly Building to await launch on its STS-125 mission to repair NASA's Hubble Space Telescope. Atlantis' targeted launch on Oct. 14 was delayed when a system that transfers science data from the orbiting observatory to Earth malfunctioned on Sept. 27. The new target launch date is under review. The space shuttle is mounted on a Mobile Launcher Platform and will be delivered to the Vehicle Assembly Building atop a crawler transporter. traveling slower than 1 mph during the 3.4-mile journey. The rollback is expected to take approximately six hours. Photo credit: NASA/Kim Shiflett

Lunar Take Off Simulator: This simulator is used by scientists at the Langley Research Center ... to help determine human ability to control a lunar launch vehicle in vertical alignment during takeoff from the moon for rendezvous with a lunar satellite vehicle on the return trip to earth. The three-axis chair, a concept which allows the pilot to sit upright during launch, gives the navigator angular motion (pitch, role, and yaw) cues as he operates the vehicle through a sidearm control system. The sight apparatus in front of the pilot's face enables him to align the vehicle on a course toward a chosen star, which will be followed as a guidance reference during the lunar launch. The pilot's right hand controls angular motions, while his left hand manipulates the thrust lever. The simulator is designed for operation inside an artificial planetarium, where a star field will be projected against the ceiling during "flights". The tests are part of an extensive NASA program at Langley in the study of problems relating to a manned lunar mission. (From a NASA Langley, photo release caption.)

An aircraft body modeled after an air taxi with weighted test dummies inside is shown after a drop test at NASA’s Langley Research Center in Hampton, Virginia. The test was completed June 26 at Langley’s Landing and Impact Research Facility. The aircraft was dropped from a tall steel structure, known as a gantry, after being hoisted about 35 feet in the air by cables. NASA researchers are investigating aircraft materials that best absorb impact forces in a crash.

In this image the NASA/ESA Hubble Space Telescope takes a close look at the spiral galaxy NGC 4217, located 60 million light-years away from Earth. The galaxy is seen almost perfectly edge on and is a perfect candidate for studying the nature of extraplanar dust structures — the patterns of gas and dust above and below the plane on the galaxy, seen here as brown wisps coming off NGC 4217. These tentacle-like filaments are visible in the Hubble image only because the contrast with their surroundings is so high. This implies that the structures are denser than their surroundings. The image shows dozens of dust structures some of which reach as far as 7,000 light-years away from the central plane. Typically the structures have a length of about 1,000 light-years and are about 400 light-years in width. Some of the dust filaments are round or irregular clouds, others are vertical columns, loop-like structures or vertical cones. These structures can help astronomers to identify the mechanisms responsible for the ejection of gas and dust from the galactic plane of spiral galaxies and reveal information on the transport of the interstellar medium to large distances away from galactic disks. The properties of the observed dust structures in NGC 4217 suggest that the gas and dust were driven out of the mid-plane of the galaxy by powerful stellar winds resulting from supernovae — explosions that mark the deaths of massive stars.
