SpaceX Cargo Mission  Possible Fuel Leak

Grounded to Investigate

SpaceX has postponed this

week’s planned launch of a Dragon cargo mission to the International Space Station to investigate a possible leak

The Dragon spacecraft was

scheduled for launch Friday morning from NASA’s Kennedy Space Center in Florida.

New target launch

 date for the Dragon cargo mission is no earlier than June 28.

SpaceX detected “elevated vapor readings”

 of monomethyl hydrazine, or MMH, fuel in an “isolated region” of the Dragon spacecraft’s propulsion system

The fueling of the

 Dragon spacecraft is one of the final steps to prepare the capsule for flight

The Dragon spacecraft has

 propellant tanks containing hydrazine fuel and nitrogen tetroxide oxidizer.
