KENNEDY SPACE CENTER, FLA. - In the transfer aisle of the |
|
Vehicle Assembly Building, workers check the rim around |
|
the nose cap of external tank number 119, the tank |
|
designated for mission STS-121. The cap was removed in |
|
order to install a new gaseous oxygen vent valve |
|
underneath. Vapors are created prior to launch as the |
|
liquid oxygen in the external tank boils off. At the |
|
forward end of each external tank propellant tank is a |
|
vent and relief valve that can be opened before launch |
|
for venting or by excessive tank pressure for relief. The |
|
vent function is available only before launch. Mission |
|
STS-121 to the International Space Station is scheduled |
|
for launch in July. Photo credit: NASA/Jim Grossmann |
