The latest Geostationary Operational Environmental Satellite, GOES-O, soared into space on June 27 after a successful launch from Space Launch Complex 37 at the Cape Canaveral Air Force Station in Florida.The GOES-O spacecraft lifted off at 6:51 p.m. EDT on a Delta IV rocket.

The crew of the International Space Station (ISS) is about to get a new eye-pod. The Tranquility node headed for the space station early in 2010 will feature a viewing dome unlike any other window ever flown in space. The dome, called the Cupola, is literally studded with windows for observing Earth, space, and the marvelous expanse of the ISS itself.The Cupola, name

On the eve of the 40th anniversary of the historic first moon landing, NASA is seeking ideas from the public, academia, and industry about how to analyze and catalog notes from spaceflight pioneer Wernher von Braun into an electronic, searchable database or other system.Von Braun was the first director of NASA's Marshall Space Flight Center in Huntsville, Ala., and a

University of Chicago researchers recently showed that dry granular materials such as sands, seeds and grains have properties similar to liquid, forming water-like droplets when poured from a given source. The finding could be important to a wide range of industries that use fluidized dry particles for oil refining, plastics manufacturing and pharmaceutical productio

For the first time, scientists working on NASA's Cassini mission have detected sodium salts in ice grains of Saturn's outermost ring. Detecting salty ice indicates that Saturn's moon Enceladus, which primarily replenishes the ring with material from discharging jets, could harbor a reservoir of liquid water -- perhaps an ocean -- beneath its surface.Cassini discovere

After a four and a half day journey from the Earth, the Lunar Reconnaissance Orbiter, or LRO, has successfully entered orbit around the moon. Engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., confirmed the spacecraft's lunar orbit insertion at 6:27 a.m. EDT Tuesday.During transit to the moon, engineers performed a mid-course correction to get the spa

Two NASA spacecraft will reach major mission milestones early Tuesday morning as they approach the moon -- one will send back live streaming imagery via the Internet as it swings by the moon, the other will insert itself into lunar orbit to begin mapping the moon's surface.After a four and a half day journey to the moon, NASA's Lunar Reconnaissance Orbiter, or LRO, w

NASA's Lunar Reconnaissance Orbiter, or LRO, and the Lunar Crater Observation and Sensing Satellite, or LCROSS, rolled aboard their Atlas V rocket to the launch pad at Cape Canaveral Air Force Station in Florida Wednesday morning in preparation for launch on Thursday. The spacecraft left its processing facility at 10:02 EDT and arrived at the pad about 35 minutes lat

The Geostationary Operational Environmental Satellite-O, or GOES-O, is scheduled for a liftoff on Friday, June 26, from Cape Canaveral Air Force Station in Florida. The one-hour launch window extends from 6:14 to 7:14 p.m. EDT. GOES-O is the second of three in the current series of geostationary weather and environmental satellites.NASA will provide television, Inter

The POES satellite system offers the advantage of daily global coverage, by making nearly polar orbits roughly 14.1 times daily. Since the number of orbits per day is not an integer the sub orbital tracks do not repeat on a daily basis, although the local solar time of each satellite's passage is essentially unchanged for any latitude. Currently in orbit we have a mo

On April 1, 2000, the National Oceanic and Atmospheric Administration celebrated the 40th anniversary of the launch of the world's first weather satellite. With today's advanced technology, and with images of clouds shown daily on television weather forecasts, it may be difficult to remember the days when there were no weather satellites.Today, the nation's environme
