Re: NSS Houston Chapter Events

This post is continuing from Dr. Stanley's presentation ...

AI training
Cloud services
Cryptocurrency mining
Large scale simulations (weather, climate, CAD)
***
Example: analyzing data before sending it to Earth saving downlink bandwidth.
***
Part 2 of this section:
<> Efficiency - better use of SPS capability
<> Scaling - not limited by Earth government permitting process
<> Stabiity ... avoid Earth's fluctuations making it easier to control temperature
***
European Union is apparently interested in this idea
ASCEND - Advanced Space Cloud for European Net zero mission and Data
$2.1 million investment in studies
***
ASCEND  Consortium
Led by Thales Alenia Space
Ariane group, Airbus, German Institute of Robotics (and others)
***
Plan ... put 300 satellites in VLEO orbit (195 miles)

Demo launch: 2025 on SpaceX Falcon 9
Full scale prototype ... late 2025
****
Lumen Orbit white paper

5 GW data center
Largest data centers today consume 100 MW
***
Sun-Synchronous orbit
Precession once a year ...
Nice slide!
Links: www.lumenorbit.com
Lumen Orbit Video (missed the link)
OK ... the link to the video is available on the web site

Re: NSS Houston Chapter Events

Continue Dr. Greg Stanley's extended presentation on Data Centers in space...

<<< other players >>>

Challenges...

Environment
   Orbital debris
    Radiation and solar flares
    Radiated infrared energy might damage nearby satellites ...all the energy not collected by solar cells must be disposed of

Costs
   5 GW unit might take 200 Starship launches
   Radiator area about half the size of the solar panels
   Radiation shielding
   (other)
***
New topic ... upcoming launches

Crew to ISS - includes two "rescue" seats
Hera (mission to asteroid Didomos) (Falcon 9)
Europa Clipper - Falcon Heay ??? 10/10/2024
Blue Origin - minus two NASA satellites
SpaceX starship = estimate: 11/26/2024
Intuitive Machines -
***
End of presentation at 20:24 UtC

Next is is The Rise of the Rocket by Christean Kapp ...
Dream Chaser ... demo flight to ISS

Re: NSS Houston Chapter Events

This presentation includes a number of slides showing historical figures...
I missed a couple...
On the screen now is:
Konstantine Tsiolkovsky
Sergi Korolev
Robert Esnault-Pelterie
***
Hermann Oberth (credited with space mirror concept, the lunar car and ION drive)
Werner von Braun

There is still time for our European members to tune in to catch the remainder of this presentation on the history of rocketery

***
Robert Goddard ... credited with muli-stage rocket - gyroscope development
***
Science fiction in the 1920's

***
The event that supercharged rocketry
Answer: The WWI Peace Treaty of Versailles
Restrictions on aircraft or heavy artillery or submarines
***
Major General Walter Dornberge (PhD engineering) 1930 began looking for alternatives to artillery
1932 watched Werner von Braun's attempt to launch a rocket at at the Society for Space Travel .... he had just written his thesis on rocket propulsion
***
Dornberger became the military head of the V1, V2 programs ... Peenemunde Facilty 1937 - 6,550 employees
***
Later Dornberger worked for Bell Corporation and Boeing, and directly for the US Air Force
****

Re: NSS Houston Chapter Events

Continuing presentation on the history of rocketry

Fritz-X radio guided bomb ... sank the Italian battleship Roma

Messerschmidt ME-163 Rocket plane

"you had to be a brave person to fly this" .,... the wheels were dropped after takeoff.

***
there were numerous others examples
***
Next section: Soviet Union ...Peenemunde and Dora....

American troops got to Dora first and secured 100 V2 and destroyed what was left

The smuggled many key researchers and most documents to the West.

Operation Osoaviakhim ... 2,500 German specialists plus 4,000 family members ... hauled east against their will.

Scores of factories went East.  They were only released in 1950 ... some as late as 1958.

***
On the Western side: Operation Paperclip ... Required President Truman to sign off on action which was against existing US law

1,600 German specialists plus family

Estimate: 10 Billion patents and industrial processes were generated by this small group

****
Note that while many of these folks received honors, one was removed after it was discovered he supervised hyperthermia experiments in prison camps.

****
Werner von Btaun in the USA

Redstone Freedom 7

Apollo program...

Time Magazine cover

**** took a break

Vikram Ambalal Sarahhai ... Founder of ISRO

Quan Xuesen Father of Modern Chinese Rocketry

American trained engineer, studied under Theodor von Karman/Prandtl. As a colonel in the US Army he interrogated Werner von Braun in 1945.

Unfortunately for the US, Quan Xuesen was driven out of the US.

***
Japan: Hideo Itokawa ... launched first "pencil" rocket in 1955

Transfer of V-2 technology via U-864 was not successful.

Re: NSS Houston Chapter Events

Here is a follow up to the meeting at North Houston NSS yesterday:

https://www.northhoustonspace.org/2024/ … f-meeting/

The link to a video is at the bottom of the page.

The presentation by Dr. Greg Stanley was excellent as always, and the history of rocketry was very well done.  The presenter is the son of one of the scientists collected by Operation Paperclip, with the difference that (apparently) the father was collected by the Soviet Union first. How he got out of Russia is included in the presentation.
