BulgariaSat-1

SpaceX does it again … relaunch and landing of another Falcon 9

Falcon 9’s first stage for the BulgariaSat-1 mission previously supported the Iridium-1 mission from Vandenberg Air Force Base in January of this year. Following stage separation, Falcon 9’s first stage will attempt a landing on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.

Personal observation … I cannot believe the bozos who comment that this is all faked based on video dropouts. When I “watched” the Mercury, Gemini, and Apollo missions live video was rare to non-existent after the initial live launch video.

You go SpaceX!

PS


CRS-11 Falcon 9 Landing

Yet another Falcon 9 landing (from yesterday June 3rd) at LZ-1. Note the arrival of the sonic boom just before landing. Starting to get routine (as it should). This was also the first re-use of a Dragon capsule (Woo Hoo).

Feels like the 60s again.

Falcon 9 Re-entry … How it survives

The video below does an excellent job of explaining exactly how the Falcon 9 survives re-entry

The heat of re-entry is due to the compression of the atmosphere ahead of the re-entering vehicle, NOT air friction. Think of a diesel engine that works by highly compressing the air in the cylinder above the ignition temperature of the diesel fuel which is then injected at maximum compression and temperature.
