NASA postponed the launch of space shuttle Endeavour's STS-127 mission Wednesday because of a leak associated with the gaseous hydrogen venting system outside the shuttle's external fuel tank.

Endeavour's next launch opportunity is July 11. This date comes after the end of an orbital sun-angle condition called a beta angle cut-out, which occurs between June 22 and July 10. The cut-out creates a thermal condition that prohibits shuttle and space station docked operations.

The gaseous hydrogen venting system is used to carry excess hydrogen safely away from the launch pad. Wednesday's leak is similar to one that prevented Endeavour's launch on June 13.

I am new to the club and enjoy trying to contact the Iss. I operate a Yaesu 857 d and have
a 2m/440 yagi that I want to use handheld. Just wondering if anybody can give me some
constuctive tips on how to get started. I am limited to my equipment.

Hello to everyone on the iss fan club. My name is Lee (WØHSN) Greenfield,Mo. I am using a
Yaesu ft-857d on 2 meters to copy the iss. I have an old 2m/440 yagi that is in good shape and
am going to put it on a tripod . Just wondered if anybody could give me some constructive hints
on how to prepare for a voice contact with iss. Thanks
