Hello Bruce

I missed also something of this discussion. I'm only a digest-reader
of the AMSAT-BB mails. Sometimes its a problem for me when Luc copies
fragments of discussions into the EU-Amsat group.

Domenico's mail was irritating. AMSAT-India does not plan to launch
a new satellite, they are looking forward, if ISRO would be so kind to
offer a new satellite structure for their 2 transponders and a launch
into a higher orbit. I wish the OM's from AMSAT-India good luck and
success for this project.

I'm not a specialist for orbits and rocket launches, but every orbit
is better than a LEO-orbit. I'm aware of that such launches are much
expensive than a LEO-launch. There were thousands of discussions about
HEO-satellites, but Luc wrote a very important thing. If we all AMSATers
do not pull at the same string, we would never have such a fantastic
satellite like P3E in a HEO. I hope my fellows from AMSAT-DL have anyhow
success with P3E and the cooperation with DLR (www.dlr.de).

Thank You for your support of AMSAT-DL.
