Analogy for low TRI funding in general - a turkey on Thanksgiving
Small turkeys have a higher number of units per pound (energy)
So for NASA, taking larger percentages of small investments will make more sense
The budget has been constrained by bulky contracts
In order to have a larger budget, looking at smaller projects over greater time will have a greater impact and a greater value for researchers
Phase ones and Phase twos
encouraging outreach and sharing, the coming symposium in Boulder
Pathways, 508 compliance (NASA comm needs ORIGINAL file to convert)
PDF format on the NIAC website
sensitive information must be protected (e.g. separate appendix
Final clients produce views, ITAR Compliance is important
Essential parts of a presentation include a table, graph, and even cards
Something like sugar….?
Please credit NASA and NIAC in all products or articles associated with NIAC studies (include logos)
Mention your NIAC award as funding/contributing to your effort
Please notify Kathy Reilly - ideas and presentation

Sputnik story absolutely riveting: Roger D. Launius National aerospace Museum
Working for the Air Force to Director of aerospace program, ownership of the museum (joke)
DO NOT touch the actual spacecraft, just the plexiglass

(BREAK)
[Insert and return to notes here]
Slamming together of Agencies >> clash and fight over ideas
Sputnik Crisis moves into NASA
Army efforts - jet propulsion lab
Low budget and attempt to create an Agency
-> NASA with early opposition from Eisenhower
DARPA creation and his concern was that we were behind, no necessity to create a bureaucracy existed for him
There will not be a space race with the Chinese as there was from Russia
There is no mutual desire for nuclear war
There are some rivalries, but there is not the death struggle fight with the Chinese as there was with Russia, children used to crawl under the desks many days, this was the environment of the space race
Remaining Incentives for Spaceflight
-Nat. Security and Military Applications
-Scientific Discovery and Understanding
-Economic Competitiveness and Commercial Activities (making $ in space), Jeff Bosen - “I’m not doing this for myself, I want to make money” without this there was the potential to pull the plug
-Geopolitics and national prestige
Mapping the schedule of American Independence with Space Exploration
Christopher Columbus >>> Yuri Gagarin
Lost Colony of Roanoke >>>> Apollo 11
Jamestown >>>> 1st Mars Colony
US Independence >>>> 1st Off-World Republic
Keeping in mind the long periods of centuries involved
Challenges for Future of Human Spaceflight
Exploit historical rationales
Build on initial experiences; broaden international activities
Enhance national security, exploration, science, technology development, commerce, and infrastructure
Step 2: “then a miracle occurs”
Scientist says, “I think you should be more explicit here in step two.”
(Joke)
QA:
What will we do now that there is no space program? Need?
- Weather security
- Military Aggression
- Necessity to make $, comm. success
- Extension of human frontier in knowledge, education, and culture: What do you mean there is no space frontier? As the correct response to the above question
Robot program out in Pluto, Shuttle program, only wakes up in event of disaster, without the shuttle program, mainstream appeal should be appropriate
What would have happened if Niel Armstrong had planted a flag and claimed territory in the name of the United States?
Outer Space treaty of 1967 we were party to, so this was prohibited in any case.
What if the first words had been drink Coca-Cola? That was an offer that was refused as well.
The only thing with economic value is a photon or an electron, how to get back to moving atoms rather than bits? The grand transit of a material transportation industry? [ie how to get results rather than spreading information only]
If you ran a train from Chicago to New York and threw away the train for tardiness, then the train would be late every time!
We are biologically entities and we do not cognitively articulate specific intellectual approach towards our personal behavior, biological processes might transcend our needs individually and importance of extending our frontiers to fulfill biological needs.
Yes.
Colonization of America success?
Spanish actually did have success
But the North American Colonies?
Successful in production of tobacco
So a product to kickstart space that could be tied to resources or knowledge or non-physical items, the challenge is: What is the product we will tie to space and create a profit from?
Right
Increasing rate of shipwrecks, raising money for an expedition from Spain or Portugal, using JFK’s warning about roaming, unsettled, throughout space to move out capabilities and the approved program for a watch vehicle which proceeds as necessitated. Scientists should not wring hands about the expediency of work, but quality
Yes
The remarkable nature of these people who are daring enough (got the cahones) to take museum spaceships once upon a time, and the importance of keeping this at the forefront of public awareness (these older ships)... stimulation of program from initial Soviet Space Program and the launch of Sputnik, what was Eisenhower’s knowledge on the topic?
He did not know, in 1952 (‘62?) the Soviet Union shot down U2, with a K[L?]-007 with the correct oversight legislation and Sputnik established for the first time legal oversight precedent
MOL - Apollo initial program Director: I am giving the stamp of approval on all of the things which have been said, and the MOL program has now been declassified
Last Question
Colonization in the last 1000 years, brings the issue of novel resources, not just things like gold, known about, but coffee, spices [indies?], which had not before been known about?
Great

E-Glider (electrostatic glider)
Some static electricity allows the balloon to fly around
Properties found in spider silk, electified in teh presence of the earth’s static atmospheric electric field (-120 V/m negative)
Observed flight pattern in spiders can be seen
Benefits to NASA:
Exploration of comets, asteroids, moons and planetary bodies is limited by mobility
[omission]
Phase 1 approach
Analyze a mission scenario using an electrostatic glider

Challenges of small bodies
Physics at airless bodies
Microgravity - challenging for locomotion
Cohesions forces - dominate partical interaction through vdW (?) forces
Solar radiation - Constantly in action
Electrostatics - [power source]
Day/night charging environment
Differences on dark side of asteroids vs. the illuminated side (+5V to -1000V)
Effects of solar wind and UV
The environment near the surface of airless bodies is electrically charged due to interactions with the solar wind plasma and UV radiation
Moon dust fountains
On the Moon, electric fields can reach 50-150 kV [kW?]
Particle ballistics under charging
Still needs to be reached and investigated,
E-glider equilibrium creates a field and static electricity
Electric fields of E`1 kV/m could take place on asteroids and and electric field fo E = -10V

From mass spectrometers to communications
Conclusions and future work
Getting sight into the physics, and to further develop simulation models, necessity of plasma physics
QA
This work was done in a laboratory in the 70s, earth does have a net electric field
Positive charges were pushed away, but if the field is conductive, there is no guarantee about the charges redistributing themselves
One critical feature is the conductive nature of asteroids, level of propensity might be needed
This has not yet been fully investigated
Control factors of craft?
There is no answer to this, but a minimum level of control necessitated
Substantial transfer of charge - Inbuilt power supply?
Dual-use cables
Solar wind rider cable, could be found in other supplies
Thank you
