SpaceX 2018

Gwynne Shotwell, President and COO of SpaceX speaking at TAMEST 2018 Annual Conference AEROSPACE on the FRONTIER OF COMMERCIAL SPACEFLIGHT.

Also note that today SpaceX successfully relaunched a previously launched F9 booster to place the GOVSAT-1 satellite into Geostationary Transfer Orbit (http://www.spacex.com/webcast) This is the second launch this year. UPDATE – first stage was not intended to land on a drone ship but survived the water landing (“This rocket was meant to test very high retrothrust landing in water so it didn’t hurt the droneship, but amazingly it has survived. We will try to tow it back to shore.” https://mobile.twitter.com/elonmusk/status/958847818583584768)

FRONTIER OF COMMERCIAL SPACEFLIGHT

Note the last video shown is appears to be the first concept 2016 “ITS” video, NOT the 2017 somewhat scaled back “BFR” video.

Falcon Heavy is scheduled to launch this upcoming Tuesday February 6.

80 Seconds

Watch (almost) EVERY SpaceX Falcon 9 landing attempted … in 80 seconds 

https://youtu.be/Gum4EVbg7_0

And that doesn’t even count two back-to-back landings last week on an Autonomous Spaceport Drone Ship (Atlantic AND Pacific) plus the landing at LZ-1 at the beginning of June. Oh … and don’t forget the May 1st landing at LZ-1. So that makes it 18 landings?

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).

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.

Latest SpaceX Mission Notes

I am replaying the video for your convenience

 

Falcon 9 first stage by the numbers 

Speed of sound = 343 m/s

Max speed on ascent = 1685 m/s (Mach 4.9 @ 68 km)

Max altitude (apogee) = 166 km

Max speed on descent = 1407 m/s (Mach 4.1 @ 65km)

Stage separation (2:47) to touchdown (9:24) = 6m 37s

Go back and rewatch the video while paying close attention to SPEED and ALTITUDE 

The Falcon 9 first stage trajectory is quite interesting …

Reusability | SpaceX

SpaceX will be returning to flight on January 8th.

From http://www.spacex.com/news/2016/09/01/anomaly-updates

SpaceX is targeting return to flight from Vandenberg’s Space Launch Complex 4E (SLC-4E) with the Iridium NEXT launch on January 8. SpaceX greatly appreciates the support of our customers and partners throughout this process, and we look forward to fulfilling our manifest in 2017 and beyond.

In preparation for the next launch, we present for your enjoyment and enlightenment a series of videos summarizing the five year history of SpaceX Falcon 9 reusability.

Enjoy …

I never get tired of watching this. It 60s Sci-Fi realized at last.

… sticks the landing

And it …

As part of Friday’s CRS-8 successful resupply launch to the International Space Station, SpaceX accomplished its first ever ocean landing of the Falcon 9 on the ASDS (Autonomous Spaceport Drone Ship) Of Course I Still Love You. Prior to this SpaceX successfully returned to Landing Zone 1 at Cape Canaveral. See The Falcon Has Landed.

SpaceX Soft Lands Falcon 9

SpaceX Soft Lands Falcon 9 Rocket First Stage

IMG_2991.PNG

Following last week’s successful launch of six ORBCOMM satellites, the Falcon 9 rocket’s first stage reentered Earth’s atmosphere and soft landed in the Atlantic Ocean. This test confirms that the Falcon 9 booster is able to consistently reenter from space at hypersonic velocity, restart main engines twice, deploy landing legs and touch down at near zero velocity.

 

After landing, the vehicle tipped sideways as planned to its final water safing state in a nearly horizontal position. The water impact caused loss of hull integrity, but we received all the necessary data to achieve a successful landing on a future flight. Going forward, we are taking steps to minimize the build up of ice and spots on the camera housing in order to gather improved video on future launches.

At this point, we are highly confident of being able to land successfully on a floating launch pad or back at the launch site and refly the rocket with no required refurbishment. However, our next couple launches are for very high velocity geostationary satellite missions, which don’t allow enough residual propellant for landing. In the longer term, missions like that will fly on Falcon Heavy, but until then Falcon 9 will need to fly in expendable mode.

We will attempt our next water landing on flight 13 of Falcon 9, but with a low probability of success. Flights 14 and 15 will attempt to land on a solid surface with an improved probability of success.

SpaceX F9R Fin Test

F9R 1000m Fin Flight | Onboard Cam and Wide Shot

From the YouTube details section:

Jun 19, 2014
Video of Falcon 9 Reusable (F9R) during a 1000m test flight at our rocket development facility in McGregor, TX. This flight was our first test of a set of steerable fins that provide control of the rocket during the fly back portion of return. The fins deploy approximately a minute and 15 seconds into the flight, and return to their original position just prior to landing. The F9R testing program is the next step towards reusability following completion of the Grasshopper program last year. Early flights of F9R will take off with legs fixed in the down position, however we will soon transition to liftoff with legs stowed against the side of the rocket with leg extension just before landing. Future test flights of F9R at our New Mexico facility will include higher altitudes, allow us to prove unpowered guidance and to prove out landing cases that are more flight-like.

Mars or bust

The Register is reporting that Elon Musk expects to have space-farers on Mars within the next twelve years. Only when the “interplanetary mission gets underway” does he expect to “float [SpaceX] on Earth-bound stock exchanges.”
