Join AIAA-Houston at Constellation Field for Spaceball – Texas
Featured
Self-funded
Join Houston-area aerospace professionals at Constellation Field Wednesday evening, Aug. 21 for “Spaceball-Texas” —
a space-themed minor league baseball game between the Sugarland Space Cowboys and Albuquerque Isotopes.
Spaceball-Texas’ proceeds go to the Future Space Leaders Foundation, a
501 c3 non-profit that provides
grants to graduate students and young professionals to present papers, attend conferences, and advance their
professional development.
Tickets are $45 and include admission and a $15 food and
drink credit.
- WHAT: Spaceball-Texas, a space-themed minor league baseball game (Sugarland Space Cowboys vs
Albuquerque Isotopes) - WHEN: 7:05pm Wednesday, August 21; gates open 6:05pm
- WHERE: Constellation Field (1 Stadium Dr, Sugar Land, TX 77498)
- WHY: Network and socialize with aerospace professionals; baseball; charitable giving
- HOW MUCH: $45/ticket; purchase here

“The Interstellar Ramjet: A Technical History”
In 1960 Robert Bussard published a solution to the mass ratio problem for interstellar flight. He laid out
the design of a starship that scooped interstellar hydrogen compressed it in a fusion reactor, extracted energy
and produced thrust. The process is similar to a terrestrial ramjet.
Bussard outlined the propulsion method, presented the equations of
motion and made general assessments of performance and
propulsion efficiency.
Sagan suggested magnetic ‘scoops’ for collecting working
matter from the interstellar medium. Fishback in 1969 calculated
important limitations on the ramjet magnetic intake and quantified
drag and radiation losses for the ramjet.
Fishback showed there was a limiting Lorentz factor for an
interstellar ramjet imposed by the material properties of the scoop
source.
Tony Martin expanded Fishback study and made some
important observations. The main problem with the concept was
using proton-proton reactions for fusion, this proves very difficult.
In 1975 Dan Whitmire made progress towards solving the fusion reactor problem of the interstellar ramjet
by noting that one could use the CNO process rather than the PP mechanism as method of fusion operation.
Bond and Jackson suggested alternative ramjet operation using augmentation. An alternative to the
Bussard Ramjet was presented in 1977. The Laser Powered Interstellar Ramjet, LPIR. This vehicle uses a
solar system-based laser beaming power to a vehicle which scoops interstellar hydrogen and uses a linear
accelerator to boost the collected particle energy for propulsion bypassing fusion reactor problems.
