Hello Leo,

You've beated me by a few!

I was making my estimation when Leo wrote to the list, but decided to
continue.

​A Falcon 9 FT (Full Thrust)​ is sheduled to launch the CRS-8 mission to
LEO today 2016/04/08 at 20:43 UTC after a long delay mainly due to the
launch failure of CRS-7 mission and because some minor delays in previous
flights. Launch site is the SLC-40 from CCAFS. CRS-8 is the ninth Dragon
cargo capsule, and its aimed to be the eigth Dragon to dock with the ISS.
Weather forecast is good and the launch window will be instantaneous.

The press kit is available here:

Live streaming is scheduled on NASA TV and SpaceX:

http://www.spacex.com/webcast

Probably NASA TV will be the first to start the live broadcast, like in
previous launches.

The following orbit was derived adapting the parameters of CRS-6 launch.
Hoewer, this launch will use a different version of the Falcon 9 launch
vehicle so it may have some extra time and cross-track errors:

DRAGON CRS-8 estimation                                  206 X 361 km
1 70002U 15502A   16099.86979167 0.00000000  00000-0  00000+0 0    02
2 70002  51.6488  43.8781 0116467  48.0571   2.9504 15.96863068    06

I suggest to replace this TLE by a real one once USPACECOM publishes an
official orbit.


There is an small visivility window about 20 minutes after launch on west
UK and North of Iberian Peninsula. The spacecraft should deploy its solar
pannels about 12 minutes after liftoff, according the launck kit, and as
Leo points in his previous post. About 4 hours after liftoff the vehicle
will start making consecutive visible passes over North America, beeing
visible in all northem Canada.

Jon.
