NASA postponed a cargo flight to the international space station because of cautious consideration that the SpaceX dragon spacecraft may be spitting fire from the wrong place According to a NASA statement late Monday, the space agency had hoped to use the Falcon 9 rocket to launch the capsule on Friday, but when the propellant was loaded into the Draco propulsion system of the Dragon spacecraft in advance, the vapor reading of monomethyl hydrazine (MMH) was detected to rise.

In other words, the sensor detected the slightest hint of a potential fuel leak, and the mission control center shut everything down.
The agency said: "once the exact source of the reading rise is determined and the cause is determined, the joint NASA and SpaceX team will determine and announce a new target launch date."
On Tuesday morning local time, NASA mission control center in Houston told astronauts of the international space station that the new launch date would not be earlier than June 28. It is reported that the mission is named crs-25.
When it finally enters orbit, the spacecraft will carry materials, equipment and scientific experiments -- including studies on immunity and aging, tests on concrete substitutes under microgravity and other investigations.
