Henry Spencer background on asteroids.

Alex Bruccoleri background on rocket physics.

Bill Gaubatz reminiscing about DC-X.
DC-X mass fraction of about 0.5.
Flight crew 3, ground crew 25.
First all-epoxy LH2 tank.
For want of a leg... A program was lost.
Remains being preserved for display at NM Museum of Space History
20th anniversary conference this August
Vertical or horizontal doesn't matter so much as operational efficiency
Vertical safer and simpler infrastructre

Ken Biba - AeroPac
Team has 2e6 N s total impulse of experience
Launched 17 deg off vertical first time
Apogee at 104,600 ft
Three flights in 5 days
Payload sponsored by Google, they made a video about it
The video cost more than the flight, and will come out in a few weeks (it's really good)
http://www.aeropac.org/100k
OpenRocket best free CFD.

Clark Lindsey
Richard Garriot made $3 million from the protein crystal experiments he did.
Put people in space, they will find ways to make it profitable.

Doug Plata - Lunar COTS
Based around harvesting lunar ice for propellant
Petition at www.lunarcots.com

John Schilling - Advanced (Non-Rocket) Propulsion Systems
More Isp is not always better, if the thrust/weight is too low.
Microwave electrothermal thruster: 1-10 kW, 1000 s Isp

Bruce Pittman - Commercial Space Scenario Planning
Refuel a Falcon upper stage at Earth-Moon L2, huge mass to Mars
To build a space entrepreneur, you don't need to build a rocket
Need better payloads
Really likes NanoRacks, small amount of money, good public-private partnership

Rice University Space Studies Professional Graduate Program/Dagmar Beck
Started from grant from Sloan Foundation.
Masters with mix of science and business education.
Requires science or engineering bachlors.
Mike Massimmo, Astronaut-on-loan
Two-year program.

John Burgener
Rather crazy presentation claiming that all sorts of things are impact craters that aren't.
Then claiming all sorts of historical events are caused by impacts (for which there is no real evidence).
Using Bible stories as his historical reference.
This guy is nutso, waiting for him to mention UFOs...

John Garvey, Garvey Spacecraft
No longer officially in partnership with Cal State Long Beach, but still working with them
Next goals: implement TVC and 100 kft flight
Evolving into a core stage for a nanosat launch vehicle.
Up to 50 kg at 450 km orbit (4 cores).
Still refining parachute recovery
Doing a lot of propylene research
Gearing up for P-19 under NASA Phase I SBIR

Martin Elvis, Harvard CfA
Currently golden age of astronomy, ending soon?
Astronomy has hit the funding wall
Applied Astronomy: Find and assay the value of asteroids
~0.1% NEOs are PGM rich
25-50% NEOs are water rich
Orbits are bad, and NEOs move fast
If 10% of asteroids are profitable,
10 survey missions, 65% chance of success
22 survey missions, 90% chance of success
44 survey missions, 99% chance of success
High-res X-ray imaging

Thanks a bunch for these summaries!

Ben Brockert, Able Space Co.
Rapid prototyping and rapid engineering
Example 10-day turnaround for a boom for Altius
Pro-bono work for SugerShot, found grain was too weak
Working on low-cost rocket test stand
Small (1200 lb) liquid sounding rocket

Planetary Defense Panel

George Herbert (via Henry Vanderbilt)
Use nukes to ablate surface
2 km: good odds of deflection
50 km: good argument for self-supporting space colonies

Henry Spencer
MIT Project Icarus: 6 Saturn Vs with 100 megaton bombs

John Schilling
Mostly a warning problem
Really want a multi-megaton neutron bomb
Surplus nukes are more X-ray devices
4 years of warning to deflect a 10 km object

Deep Space Industries - Rick Tumlinson
40-50 year overnight success
Movement started by Gerry O'Neill
DSI is a platform to create a market
Love Planetary Resources, they tolerate us
Focus is not returning PGM
Focus is space resources to use in space
Water, asphalts, metals
Replace comm sats with large comm platforms
Development of an industrial space economy
Cost plummeting
CubeSats are good
Fireflies: one-way prospectors
Five targets per year by 2020
Three in first salvo
Dragonflies: small sample return vehicles
Planetary Defense Plan: scramble in-space interceptors to inspect newly discovered close-pass asteroids
Played video
Opening web shop soon with meteorite stuff
It's possible the NASA capture mission could work, if they do it like COTS/CCDEV

Stratofox Aerospace Tracking Team - Ian Kluft
Have recovered highest alt. amateur balloon (CNSP-10) and rocket (CSXT)
Black Rock, NV much cheaper than federal ranges
CNSP-11 was the "little balloon that could" and flew from California to Algeria
CNSP-18 repeated it by going from California to Morocco

HySor Student Hybrid Rocket Team - Bryce Schaefer
CU Boulder Grad student project
Began in fall 2010, launch in spring 2014
920 lb thrust, 320 s Isp, N2O/HTPB
Simple titanium showerhead injector
Igniter embedded in fuel grain, heats the fuel before the oxidizer valve opens
Graphite nozzle
Static test fires at Frontier Astronautics in WY (ex-Atlas missile silo)
FAA needs to know it's safe, and not just a pipe bomb
Nozzle fell off after 8 seconds of thrust
Still first time to get thrust data

And that's it for today; notes will be lighter tomorrow as I have other stuff to do.

To clarify--Ben helped us test using one of our STEM booms as a sort of waveguide for sending WiFi signals, and I think the turn around was less than a week, but I lost count. Fun project, and Ben did a great job for us.

So, did ya call it PringleBoom?

Interesting DSI says they support a COTS (SAA) methodology for NASA asteriod retrieval mission. PR already made statements supporting this.
