First Delta IV Heavy launch
« on: December 06, 2004, 02:49:46 PM »
The first Delta IV Heavy ELV is expected to launch this Friday afternoon, December 10, 2004, sometime between 2 and 5 pm (roughly).

Should be quite a show!

Thanks for the link and bringing this topic up.  That rocket can haul 21,000kg into LEO!  I am impressed by the numbers they are showing.  What I really enjoyed was the development chart for future types of Deltas and they (Boeing) had one on par with the Saturn 5.

Interesting design.  I think that is the first rocket I've seen that uses LH2/LO2 in all stages.

Does anyone know if there has been any talk of man-rating these machines?

I think its main purpose or should I say selling point is hauling up sattelites into geostationary orbit.  They built this to compete directly against the Ariane 5 in my opinion.  I too was wondering if it could haul the CEV, that is why I went to the Boeing site to find out about the LEO.  When they listed the LEO mass, ISS was listed with the orbital inclination (51 degrees).
I remember seeing some of the CEV concepts on both Delta and Atlas rockets.

Thanks SM . . . .

I can see this having implications in the Moon Mars & Beyond initiative proposed by President Bush.

We may, hopefully, be in for some interesting times in the next dacade.

Here is more news about the Delta Heavy, I copied this article from Space.com, written by Leonard David:

Dec 8, 2004
Nanosats Onboard Delta 4-Heavy Booster

Two “nanosatellites” are sitting atop that Delta 4-Heavy rocket – the maiden flight of the huge booster that’s set for liftoff on December 10.

The nanosatellites weigh about 60 pounds and are the size of a large microwave oven. They are the high-tech offspring of students and faculty members at New Mexico State University (NMSU), the University of Colorado at Boulder and Arizona State University.

The main scientific project for the satellites will be to use digital cameras to capture stereo images of cloud formations that can later be converted into 3-D images.

Another goal of the project is to test how well commercial-grade components work in space. Most of the parts used for the nanosatellites, including the digital cameras, were ordered from catalogs and have not been space-proven, said Stephen Horan, a professor of electrical engineering at NMSU who directed the university's participation in the project.

If the project shows that nanosatellites can be operated successfully with commercial-grade components, Horan said, it could help facilitate university researchers to build nanosatellites that are less expensive than traditional satellites. Each of the nanosatellites built for this project cost less than $100,000.

The nanosatellites were built as part of the University Nanosat Program, a competition sponsored by the Air Force Office of Sponsored Research, the Defense Advanced Projects Agency and NASA.

Weather concerns have forced a postponement of the launch to Saturday at 2:31 pm.

Well, you didn't miss anything Kel.

Technical snafu.

Launch date TBD.

The launch is back on.  Here is news from Boeing's Delta site:

The launch team is now working to launch windows for the Delta IV Heavy vehicle on the 21 st & 22 nd December 2004. T he two hour and 56 minute ( 2:56) launch windows open at 2:36 pm EST and close at 5:32pm EST. The Delta IV Heavy vehicle will be launched from Cape Canaveral Air Force Station, Fla.

A launch readiness review is scheduled for 20 December 2004.

Boeing Launch Services will continue to update this website with the latest information about this important mission. For additional information, call the Boeing Launch Hotline for updates: (714) 896-4770.

So far so good.  It lifted off at 4:50pm EST.  Five minutes into it the boosters seperated.  One minute ago the second stage ignited.

It looks good.
