Riding a column of brilliant flame from nine Merlin 1D main engines, the Falcon 9 rocket climbed away from Cape Canaveral’s Complex 40 launch pad at 10:36:09 a.m. EST (1536:09 GMT) Friday, turning northeast over the Atlantic Ocean to align with the space station’s orbital track. -Photo : rke |

Les choses ont bien changé. Autrefois, après chaque
décollage, on pliait bagage au plus vite pour redescendre du toit. Maintenant
notre attention se focalise davantage sur le retour du 1er étage de
la fusée. On doit scruter toute l’étendue du ciel, la tête bien inclinée pour
l’apercevoir. Et c’est seulement lorsque ses moteurs sont allumés générant
comme une grosse étincelle, qu’on le distingue enfin. L’étage devient de plus
en plus visible. On remarque au loin la trajectoire légèrement recourbée que le
mène à son point de chute. Une chute d’ailleurs parfaitement maîtrisée et,
contrairement à un hélicoptère qui se pose comme un papillon, la descente d’un
étage de fusée est telle une grosse flèche qui fait mouche !

Rappel
C'était mon 5e lancement sur le toit du VAB. Pour rappel voici mes 2 aventures d'autrefois :
1. Je suis resté bloqué dans les toilettes du VAB de la NASA ( 5 décembre 2014) - Cliquez ici
2. Brrr… à +15 degrés C., c’est plutôt
froid pour voir décoller la fusée sur le toit du VAB ! ( 2 mars 2013) - Cliquez ici

SpaceX-Falcon 9: the 1st stage falls from the sky like a big
arrow that reached its target!

[Cape Canaveral, Florida, December 15, 2017, rke
] – "If an accident occurs, for your safety, evacuate
immediately to the west side of the building. " While we are installed at 525
feet on the famous VAB (on the roof), the orders have not changed. In case of problems,
so an explosion as was the case on September 1, 2016, with the rocket Falcon 9
(which had destroyed a Facebook satellite), you must drop everything and to
leave at full speed. That said, as soon as we are on the roof, the vast
panorama that presents itself to our eyes gives a feeling that nothing can
happen. We are like eagles on the lookout for launch towers that can be clearly
seen in the distance (we are still 5 km as the crow flies). And from this
height, we see better ignition engines.
Things have changed a lot. In the past,
after each take-off, luggage was packed as fast as possible to get off the
roof. Now our attention is focused more on the return of the 1st stage of the
rocket. We must scrutinize the whole expanse of the sky, our head well inclined
to see it. And it is only when its engines are lighted generating like a big
spark that one finally see it. The 1st stage becomes more and more visible. In
the distance we can see the slightly curved path that leads to its point of
fall. A fall perfectly controlled and, unlike a helicopter that lands like a
butterfly, the descent of a rocket stage operates like a big arrow that reached
its target.
