NASA has been forced to impose yet another delay on the launch of the space shuttle Atlantis due to a fault discovered with a liquid hydrogen fuel sensor. The latest delay follows a delay a day earlier caused by an electrical fault in one of the shuttle's three fuel cells.
The hydrogen fuel sensor is a critical
component of the shuttle's launch system as it regulates when the
engine should shut down based on how much fuel is left in the tank.
Fuel sensor problems also delayed space shuttle Discovery launches in 2005 and earlier this year.
The
Atlantis launch, which involves a crew of six astronauts, aims to
recommence contruction of the international space station, which has
remained only partially built since the space shuttle Columbia disaster
in January 2003 when seven international astronauts perished.
A new launch date for Atlantis has been set for Saturday
Meanwhile,
the Russians have their own rendezvous with the space station planned
for September 18, which will carry two new space station crew and the
first female space tourist, Iranian-born American technology
entrepreneur Anousheh Ansari aboard the Soyuz space capsule.
Ms
Ansari, chairman and co-founder of consumer technology company Prodea
Systems, is believed to be paying at least US$20 million for the
privilege, based on the previous three tourist trips into space.
