Falcon 9 first stage test firing in March
After a successful test firing of its first stage rocket in March earlier this year, SpaceX had targeted a May launch date, and has made great progress through technical issues to make the June 4th attempt. The window opened at 11:00am EDT and will last until 3:00pm EDT today. Weather looks good with a 60% chance of favorable conditions. A telemetry issue has prevented an on-time lift off, but a stronger antennae is currently being deployed with hopes of a 1:00pm EDT lift off.
