SpaceX : The Falcon 1st Stage Dark
as a Controlled Meteor
[Cape Canaveral, Florida, December 17, 2017, rke] – "He
left like a bird in the blue sky finally free and happy," said the song in
the words of the French singer Georges Moustaki.
If the launching of a rocket becomes as trite as the departure of a car, each
shot remains and will remain in a way a feat, because it is each time a
condensed human intelligence that boosts the technique until at the first
second of take-off. That's why adrenaline rises little by little until the
rocket takes off. The mastery of the landing of a stage is itself a
technological prowess all the more important, because many engineers, therefore
humans, who have designed the mathematical algorithms necessary for the descent
of the end of the rocket that rushes on Earth like a meteor and whose descent
must be mastered. And though Jessica Jensen, director of SpaceX's Dragon
mission, said she prefers landing rather than taking off (see video), following
my post-conference question after Falcon's last take-off, the two phases of
flight is an accomplishment.

[Cape Canaveral, Florida, December 16, 2017, rke] – With a touch of
nostalgia, I remember lift-off Saturn rockets where, being a kid, I watched
Apollo flights on TV. At the time, in the late '60s and early' 70s, two
featured presenters hosted shows on the subject, mostly live. First of all there
was Georges Kleimann (died in 2010) for French-speaking Switzerland (formerly
TSR) and then and above all Dr. Bruno Stanek for German-speaking Switzerland (SRF).
Although, in its time, I did not really want to learn German, I always had
great admiration for Bruno Stanek who
brought - and still brings via the web - a scientific added value. On the
occasion of my presence here in Cape Canaveral, I asked him why he thought
SpaceX is better than any other space company today. From Switzerland, he
answers me through this blog, which, in a way, honors me.

Dr. Bruno
Stanek :« SpaceX has succeded to rise to
the top of all rocket developers within less than a decade, while the ancient
leaders, despite all government support, seem to have made no technological
progress within the same decade. SpaceX has demonstrated the ability to land
the expensive first stages and offered the prospect to launch for a fraction of
the cost on a regular basis. Their technology of a sub-frozen
Methane-LOX-engine is progressed to the point, where reaching Earth orbit on a
single stage becomes feasible. This makes further breakthroughs much easier:
second stages are built like orbiters, make payload fairings obsolete, can be
refueled in Earth orbit and can fly to either the Moon or Mars with just more
or less fuel. Choosing Methane instead of Kerosene let's them produce CH4 from CO2 and H2O on Mars for the return flight. Building their own launch complex in
Boca Chica (South Texas) makes them independent from government and military
facilities - and most limits launching super-heavy rockets. What do you need
more? And they have additional proprietary ideas that are not easy to copy.

] – "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.

PAD 40
tribulations : when reporters & photographers go home empty-shooted
No shoot this time. Maybe later. -Photo : rke
[Cape Canaveral, Florida, December 15, 2017, rke] - The subject of
predilection, do you know what is it ? PAD 40 ! As you can see on the map
opposite, this is a SpaceX-Falcon (SLC 40) launch pad. Since the Falcon rocket
explosion on September 1, 2016, all SpaceX launches took place there! So it's
been over a year, it was a big blow for Elon Musk's company. The explosion of
the launcher was caused by an initial explosion of one of the three helium
tanks inserted inside the upper-stage liquid oxygen tank. The shock waves
vaporized the liquid oxygen. Fine droplets of vapor that formed then ignited
the kerosene that shattered the launcher and the satellite on board. Since that
date, SpaceX's other take-offs have been from PAD 39A, which SpaceX has bought
from NASA.
So, I am the only foreign reporter accredited However, the launch of SpaceX Dragon CRS-13
expected tomorrow Friday at 10:35 am local time, 16:35 pm (Swiss time), is
taking place precisely on the famous PAD 40. NASA, which deals with the media
as a provider for SpaceX, we concocted an exclusive visit to the place, night
at 1am, to make more fun. I was therefore looking forward to seeing the
renovation of this place.
Fifteen photographers and reporters -
including myself, the only foreigner in the contingent - had a meet at the
parking of one of the two badge buildings (PIDS). After a good hour of waiting
in the bus that was to bring us to the launch site, SpaceX announced that it
was better to abandon the trip to PAD 40, as was the case three days before the
first launch attempt. We came home empty-handed not taking it too bad for some
of us. SpaceX seems to have needed more time to refine the site and its rocket. This PAD 40 causes us a lot of tribulations.

– While the launch of SpaceX Dragon CRS-13 is slow due to launcher verification
procedures (as a precaution), journalists and reporters have been invited to
attend a rich scientific briefing called "What's on board". Yes, the
Dragon capsule not only carries material to the astronauts of the International
Space Station (ISS), but also scientific experiments, a dozen of them are
embarked and I will make you discover some over my American trip.
Clarification. In orbit, the microgravity
conditions that allow to investigate the impacts on biological life and fluid
flows. The experiments flying on SpaceX/CRS-13 will be joining some of the 329
experiments during Increment 53/54. Bringing us, to date, up to 2’465
experiments, and over 1’300 publications, that have come from space station
research.
...with many very attentive young people.

A startup company, Biorasis, seeks to use the microgravity
environment of the space station to improve the accuracy of wireless, medically
implantable glucose biosensors for day-to-day diabetes management. The Biorasis
Glucose Biosensor investigation seeks to improve the accuracy of a wireless
medically implantable continuous glucose biosensor (Glucowizzard) for day - to
- day diabetes management.
The Center for Advanced of Science in Space (CASIS) sponsored this research in partnership
with Boeing/MassChallenge. Slow glucose transport within human tissue (through
the capillary walls and surrounding tissue toward the sensing site of the
biosensor) can create delays of up to 2 0 minutes in real - time monitoring of
glucose levels. This delay can be detrimental in achieving tight glycemic
control, which has been linked to serious secondary complications in patients
with diabetes. The ISS provides a microgravity environment in which reduced
fluid movement allows precisely monitoring of the role of diffusion in glucose
transport, thus improving the mathematical models that determine the accuracy
of the Glucowizzard continuous glucose monitoring biosensors.

Otherwise, the Houston
Methodist Research Instituteis partnering with the pharmaceutical
leader Novartis on a rodent research investigation to evaluate the efficacy of
an implantable drug delivery system that could assist those with muscle atrophy
on Earth. Launchpad Medical will send a synthetic bone material, capable of
adhering bone to metal within minutes to accelerate repair. This is an ideal
environment to evaluate a healing response and development of effective
treatments for patients needing bone repair.
