STEREO SOLAR OBSERVATORIES LAUNCHING ABOARD DELTA II ON OCT. 25

Launch of NASA's STEREO spacecraft is scheduled for Wednesday, Oct.
25, aboard a Boeing Delta II rocket from Pad 17-B at Cape Canaveral
Air Force Station, Fla. The launch window is 8:38 to 8:53 p.m. EDT.
Should the launch be postponed for 24 hours for any reason, the
launch window is 8:26 to 8:41 p.m. EDT, or for a 48-hour
postponement, 8:32 to 8:47 p.m. EDT.

STEREO consists of two spacecraft that together comprise the first
mission to take measurements of the sun and solar wind in 3-D. This
new view will improve our understanding of space weather and its
impact on the Earth.

During the two-year mission, the nearly identical spacecraft will
explore the origin, evolution and interplanetary consequences of
coronal mass ejections, the most violent explosions in our solar
system. When directed at Earth, these billion-ton eruptions can
disrupt satellites, radio communications and power systems. In
addition, energetic particles associated with these solar eruptions
are hazardous to scientific spacecraft and astronauts.

Truly an international effort, many portions of the STEREO instruments
were provided by the United States, the United Kingdom and several
European countries. The Johns Hopkins University Applied Physics
Laboratory, in Laurel, Md., designed and built the spacecraft and
will operate the twin observatories for NASA during the mission.
NASA's Goddard Space Flight Center in Greenbelt, Md., is responsible
for the project management. The NASA Launch Services Program at
Kennedy Space Center and Boeing Expendable Launch Systems are
responsible for the launch.

LOCKHEED MARTIN INSTRUMENT TO MONITOR SOLAR ERUPTIONS ON LATEST NASA SUN MISSION

PALO ALTO, CALIF.,October 19, 2006

The Extreme Ultraviolet Imager (EUVI) instrument  - designed and built at the Solar and Astrophysics Laboratory of the Lockheed Martin [NYSE: LMT] Advanced Technology Center (ATC) in Palo Alto - will soon begin returning stereo images of the Sun's corona as part of NASA's Solar Terrestrial Relations Observatory (STEREO). STEREO will utilize two nearly identical spacecraft on different trajectories to study the most energetic events on the surface and in the lower atmosphere of the Sun, and their travel through interplanetary space.

Data from spacecraft instruments will allow scientists to construct the first ever three-dimensional views of the Sun, providing a new perspective on Coronal Mass Ejections (CMEs). CMEs are violent explosions on the surface of the Sun that can propel up to 10 billion tons of the Sun's atmosphere - at a million miles an hour - out through the corona and into space.

The two STEREO spacecraft will be launched together on a Delta-II on Oct.25, 2006 from Cape Canaveral Air Force Station, Fla. Both spacecraft will fly by the Moon taking advantage of a gravity assist that will propel one of the observatories into an orbit "ahead" of the Earth in its journey around the Sun, and the other "behind" our planet as it makes its yearly revolution.

EUVI is one element of an instrument suite on each STEREO spacecraft called SECCHI   - the Sun-Earth Connection Coronal and Heliospheric Investigation - under the direction of Principal Investigator Dr. Russell Howard of the Naval Research Laboratory of Washington, D.C. SECCHI comprises a suite of telescopes, including three white light coronagraphs and EUVI.

"We've been studying CMEs for a long time, but SECCHI will offer us new insight into the structure and evolution of the solar corona in three dimensions, while EUVI focuses specifically on the initiation and early evolution of CMEs," said Dr. James Lemen, Lockheed Martin co-investigator on SECCHI. "EUVI and the other instruments on SECCHI will follow the propagation of these events through the corona, out into interplanetary space and all the way to Earth, giving us a comprehensive view of these enormous phenomena."

Coronal mass ejections, which are often associated with solar flares, can take several days to reach the Earth. Fast, powerful ejections give rise to geomagnetic storms, which can disrupt radio transmissions and induce large currents in power transmission lines and oil pipelines. They have resulted in large-scale failures of the North American power grid and greatly increased pipeline erosion. CMEs also can generate spectacular auroras in Earth's polar skies, but can disrupt spacecraft and be extremely hazardous to astronauts.

NASA Goddard Space Flight Center in Greenbelt, Md. manages the STEREO mission. The Johns Hopkins University Applied Physics Laboratory in Laurel, Md. designed and built the spacecraft. The laboratory will maintain command and control of the observatories throughout the mission, while NASA tracks and receives the data, determines the orbit of the satellites, and coordinates the science results.

The Solar and Astrophysics Laboratory at the ATC has a long heritage of spaceborne solar instruments including the Soft X-ray Telescope on the Japanese Yohkoh satellite, the Michelson Doppler Imager on the ESA/NASA Solar and Heliospheric Observatory, the solar telescope on NASA's Transition Region and Coronal Explorer and the Solar X-ray Imager on the GOES-N environmental satellite. The laboratory also conducts basic research into understanding and predicting space weather and the behavior of our Sun including its impacts on Earth and climate.

The ATC is the research and development organization of Lockheed Martin Space Systems Company (LMSSC). LMSSC, a major operating unit of Lockheed Martin Corporation, designs, develops, tests, manufactures and operates a variety of advanced-technology systems for national security, civil and commercial customers. Chief products include human space flight systems; a full range of remote sensing, navigation, meteorological and communications satellites and instruments; space observatories and interplanetary spacecraft; launch vehicles, fleet ballistic missiles; and missile defense systems.

STATUS REPORT: ELV-102006

EXPENDABLE LAUNCH VEHICLE STATUS REPORT

Mission: STEREO
Launch Pad: 17-B, Cape Canaveral Air Force Station
Launch Vehicle: Boeing Delta II
Launch Date: Oct. 25, 2006
Launch Time: 8:38 - 8:53 p.m. EDT

STEREO, at Pad 17-B atop the Boeing Delta II rocket, was encapsulated
into the Delta II fairing on Thursday. The second stage is scheduled
to be loaded with storable propellants on Monday, Oct. 23. Because
this is a hazardous operation, the launch pad will be closed to all
other work.

The Delta II flight program verification, a complete integrated
electrical and mechanical test with STEREO and the rocket, was
successfully completed on Monday. There are no significant launch
vehicle or spacecraft issues or concerns at this time.

On launch day, Oct. 25, the gantry-like mobile service tower is
scheduled to be retracted from around the Delta II at 11:15 a.m. The
terminal countdown procedure begins at 5:38 p.m. Engineers are
scheduled to begin loading the first stage with RP-1, a highly
refined kerosene fuel, at 5:58 p.m. The launch team will load the
first stage with liquid oxygen 50 minutes later at 6:48 p.m. Liftoff
is scheduled for 8:38 p.m. at the opening of a 15-minute launch
window.

So the first stage has a RS-27A engine and burns RP-1 and LOX. The third stage is the Star-48B solid rocket motor according to http://www.boeing.com/defense-space/space/delta/delta2/delta2.htm , which is usually required for GTO, space exploration and planetary missions. Do you mean that the Star-48B solid rocket motor is being fueled with N2O4 and Aerozine 50? If so what does the second stage (the stage with the AJ10-118K engine) use for fuel and oxidizer?

The 3rd stage is the solid STAR-48B
The 2nd stage is liquid.  I was referring to that it was loaded yesterday.

Since it appears that all of us missed the pre-launch press conference here it is for download: http://www.space-multimedia.nl.eu.org/index.php?option=com_content&task=view&id=1083

According to Omar Baez(NASA Launch Manager for this flight), they're working two technical issues. One relates to two STEREO spacecraft computers.

Yesterday the computer on MESSENGER restarted itself and since the STEREO computers share the same motherboard design, they want understand what caused MESSENGER's computer to perform the restart and make sure it doesn't happen on the STEREO computers.

The second one is with the Delta II fairing. Some closeout photos of the fairing showed to washers on some nuts had not been installed.

A decision whether to proceed with a launch tommorow wwill be made some time after 6 pm EDT tonight.

Forgive me if someone has already mentioned this, but the following story tells us that today's launch will use the first Delta II "built entirely" at Decatur.

http://www.decaturdaily.com/decaturdaily/news/061025/rocket.shtml

I seem to recall that the leaky tank issue had something to do with the move from Pueblo.  It will interesting to see if any other "gotcha's" appear with this flight.
