Default Delta IV vs. Sea Launch Zenit

Ok, I say the Sea Launch Zenit 3SL will be first.
Why?

- Weather for Delta 4 for Cape launch may be problematic - unlikely for Sea
Launch
- Last thing Boeing needs right now is a failed Delta 4 launch, so
conservatism will reign
over the "go/no-go" decisions right up to launch time.

Looks like you may have called this right. Boeing announced
a further Delta IV delay today that drives the launch date
back to 8/6 at the earliest. Meanwhile, Sea Launch remains
on track for an 8/7 launch.

Sea Launch sailed from San Diego today (8/1/03) with a Zenit 3SL, bound
for the equator for a scheduled 8/7 launch of Echostar 9/Telstar 13.
Meanwhile, the third Delta IV stands on Cape Canaveral Pad 37B, waiting
for a now-delayed 8/4 launch with DSCS 3-B6.

Any wagers as to which Boeing Launch Services mission will get off the
"ground" first?

Not surprised at all ... can you say cork insulation?
(a.k.a. Delta 2 Heavy delays in July)
"The launch is being delayed so that additional testing to verify launch
vehicle insulation integrity can be accomplished." .. Boeing IDS News Bureau

Last thing the USAF needs is a wrecked EELV program --- both solutions and
contractors have different issues and problems --- precarious in current
economic climate.



Meanwhile on the West Coast

Sea Launch Sails to Equator to Launch EchoStar IX/Telstar 13 Satellite


LONG BEACH, Ca., August 1, 2003 - The Odyssey Launch Platform and the Sea
Launch Commander have departed Sea Launch Home Port for the launch of the
EchoStar IX/Telstar 13 satellite for EchoStar Communications Corporation and
Loral Skynet. Liftoff is scheduled for August 7, in a two-hour launch window
that will open at 8:31 pm PDT (3:31:00 GMT).



... the race is on ..

Delta IV Launch of DSCS III B6 Postponed

ST. LOUIS, Aug. 2, 2003 - Boeing [NYSE: BA] and U.S. Air Force officials
postponed the launch of the Defense Satellite Communications System
spacecraft, DSCS III B6, aboard a Boeing Delta IV rocket from Cape Canaveral
Air Force Station (CCAFS), Fla.

The launch team will be replacing an antenna associated with the rocket's
flight termination system, and the work will not be completed in time to
make the last day of the range availability assigned for this mission on
Aug. 5.

Boeing is coordinating with the Air Force to determine a new launch date
based on the next availability in the launch range schedule at CCAFS.

Well, Sea Launch successfully delivered its payload. And now, it
looks as if Delta IV will be delayed to the end of August due to the
Range being booked in the next few weeks for Titan IVB and SIRTF-Delta
IIH. Spaceflight Now notes the SIRTF-Delta IIH will take the
distinction of being the 300th Delta launch. A marketing hype if
there ever was one to include Delta IV in the same series as Delta II.

Sea Launch Successfully Launches EchoStar IX/Telstar 13 Satellite into Orbit

LONG BEACH, Cailf., AUG. 7, 2003 - Sea Launch, the world's most reliable
launch service provider for heavy commercial communication satellites, today
successfully launched the EchoStar IX/Telstar 13 satellite to orbit for
EchoStar Communications Corporation and Loral Skynet.

A Zenit-3SL launch vehicle lifted off at 8:31 pm PDT (3:31 GMT) from the
Odyssey Launch Platform positioned at 154 degrees West Longitude, on the
Equator. All systems performed nominally throughout the flight. The Block
DM-SL upper stage inserted the 4,737 kg (10,443 lb) EchoStar IX/Telstar 13
satellite into a high perigee geosynchronous transfer orbit. As planned, the
spacecraft's first signal was acquired at 9:46 pm PDT (4:46 GMT), shortly
after spacecraft separation, by a ground station in Western Australia. The
spacecraft will be located in geostationary orbit at 121 degrees West
Longitude.
