NASA managers today determined that the space shuttle Endeavour will not launch before Sunday, May 8, but will not officially set a new launch date until early this week.
The scheduled launch of Endeavour’s last voyage on Friday was scrubbed because of a failed heater circuit associated with the space shuttle’s hydraulic power system.
