Thank you for volunteering for SEED again this year. It is a great experience.
We can assure first timers that at the end you will feel tired, but rewarded!
Please bring your solarscope, spectroscope, solar viewers, and other solar projects.
Please bring/ help load our completed P. M. Planets and Asteroids.
We will mount them along the road according to relative distance, or at your station.
If you have posters or information
that we can put on our Solar Astronomy bulletin board
(plenty of room!),
please let us know,
and bring it/them with you, or to our meetings beforehand.
Thanks for being involved!
Here are some suggestions to help everyone:
Take care of yourself with HAT, sun block, long sleeve shirt, pants or long skirt,
Bring your equipment, project, etc. - anything about the sun! and/or The DAWN Mission
Come early: We will be here at 8:30AM to
set up equipment, pass out free t-shirts and ID tags, set up posters, get organized.
You will also get a Free Lunch.
Please come and help.
Thank you,
Stan Howard
VP Observing
PS: Our Trivia Question this year: How does the DAWN spacecraft use ion propulsion?
Answer:
The DAWN spacecraft used ion propulsion
1. to get the additional velocity needed to reach Vesta once it left the Delta rocket,
2. to spiral to lower altitudes on Vesta,
3. to leave Vesta, and
4. to cruise to Ceres.
It will use ion propulsion
5. to spiral to a low altitude orbit at Ceres.
Ion propulsion makes efficient use of the onboard fuel
by accelerating it to a velocity ten times that of chemical rockets.
This efficiency is measured in terms of the specific impulse of the fuel (Isp).
- See more at: http://dawn.jpl.nasa.gov/mission/ion_prop.asp#sthash.3QCszH9X.dpuf
Ion thrusters create very low levels of thrust compared to conventional chemical rockets
but achieve very high specific impulse, or propellant mass efficiencies,
by accelerating their exhausts to very high speed.
