Arianespace Update: Flight 159 with the Intelsat 907 telecommunications satellite
A historic moment occurred today (Jan. 30) when the final Ariane 4 rolled out of its assembly building for transfer to the Spaceport’s ELA-2 launch zone in French Guiana.
The Ariane 4 is scheduled to lift off in the early morning hours of February 12, carrying the Intelsat 907 telecommunications satellite.
For our update on this last Ariane 4 launch, see the Mission Log on Arianespace’s Web site:
Space is certainly a cold place, but spacecraft have to face extremely high temperatures when they are exposed to the Sun’s radiation. However, there are other extreme situations in which spacecraft are subject to tremendous heat. ESA’s spacecraft must endure temperatures from hell…

Today, about 90 percent of the hardware for Jules Verne, Europes first Automated Transfer Vehicle (ATV) spaceship that is to fly towards the International Space Station (ISS) in September 2004, is already built.
Nominations for NASA’s Educator Astronaut Program are in high orbit. Since the Program’s kickoff January 21, more than 1,300 teachers have been nominated to become members of the Astronaut Corps. Texas leads with 324 nominations, followed by 223 from Florida, and California with 163.
The Educator Astronaut web site is also receiving a high volume of traffic. More than 4.8 million visits have been recorded during the first 10 days of the program.
The nation’s newest environmental satellite, GOES-12, is being readied for operations, NASA and the Commerce Department’s National Oceanic and Atmospheric Administration (NOAA) announced today.
GOES-12 is equipped with an advanced instrument for real-time solar forecasting. The Solar X-ray Imager (SXI) aboard the satellite will enable forecasters and scientists to detect solar storms that could impact billions of dollars worth of assets.
An experiment aboard the Space Shuttle Columbia (STS-107) has uncovered a new phenomenon. Researchers made the discovery studying the role of aerosol particles in global climate changes.
The Mediterranean Israeli Dust Experiment (MEIDEX) is gathering data about aerosol plumes emitted from deserts. MEIDEX builds on previous studies that showed aerosol particles might be one of the primary agents that can offset warming.
NASA sponsored scientists have discovered by knowing the salt content of the ocean’s surface, they may be able to improve the ability to predict El Nino events. Scientists, studying the western Pacific Ocean, find regional changes in the saltiness of surface ocean water correspond to changes in upper ocean heat content in the months preceding an El Nino event. Knowing the distribution of surface salinity may help predict events.
Somewhere in the distant, old Universe, a population of stars hide undetected. They were the first to form after the birth of the Universe and are supposed to be far bigger in mass than any star visible today.
Astronomers know they must have been out there: only in this way could they solve the riddle of the origin and composition of stars in today’s Universe. A couple of ESA missions will help astronomers search for this elusive population.
NASA and two Japanese government agencies are collaborating on a snowfall study over Wakasa Bay, Japan. Using NASA’s Earth Observing System Aqua satellite, research aircraft and coastal radars to gather data, the joint effort is expanding scientific knowledge about where precipitation falls.
NASA has selected nine research proposals for negotiation of Phase 2 contract awards for the 2001 Small Business Technology Transfer (STTR) Program.
