Flight 4 of Falcon 1
Falcon 1 is currently cleared for liftoff sometime between 4 p.m. and 9 p.m. (California time) tomorrow, Sunday September 28th. Of course, if we see anything that requires investigation, the launch will be postponed, but we’ll let you know as soon as we know. As with prior flights, you can access the webcast from the SpaceX site: www.spacex.com

Half-way through the terminal count.
Posted September 28, 2008 - 16:06 PDT
We are T-10 minutes and counting. Terminal (automated, hands-off) count has begun!

Ground winds are ok for launch.
Posted September 28, 2008 - 15:53 PDT
More than three-quarters of the way through the countdown procedures.
Posted September 28, 2008 - 15:49 PDT
First stage is 95% full of liquid oxygen (LOX) and completely full of fuel (RP-1). LOX topping procedure has begun. Second stage is 97% full of LOX, and 100% full of RP-1.

First stage is 95% full of liquid oxygen (LOX) and completely full of fuel (RP-1). The remaining 5% of LOX will be topped off later in the countdown. Second stage is 77% full of LOX, and 68% full of RP-1.
Posted September 28, 2008 - 15:02 PDT
After a 15 minute hold, the clock is again counting down towards launch.

SpaceX公司宣布Falcon 1第四次发射终于获得成功……
不错，7.9M USD的东西。
这下空军、NASA和Musk都能送口气了，下一步就看falcon9了

正是，第三次发射和第四次发射使用的是Merlin 1C发动机，起飞推力较Merlin 1A更大，因此火箭可以有更大的起飞重量，但是运载能力略有下降，不过Merlin 1C最主要的价值还是给Falcon 9和Falcon 9 Heavy铺路
