History and Astrodynamics Lunch and Learn: Reproducing an Apollo Applications Program Single-Launch Human Venus Flyby Trajectory

Reproducing an Apollo Applications Program Single-Launch Human Venus Flyby Trajectory
by Daniel R. Adamo, Astrodynamics Consultant, AIAA Senior Member, and Distinguished Lecturer

An event of AIAA Houston Section History technical committee Chair: Douglas Yazell; Members: Ted Kenny, Chester Vaughan
AIAA Houston Section Astrodynamics technical committee Chair: Dr. Albert Allen Jackson IV; Members: Douglas Yazell, Dr. Tim Crain

As proposed to the Apollo Applications Program by NASA’s Manned Spacecraft Center in 1967, a single Saturn 5 launch of Apollo-derived hardware could send a crew of three on a Venus flyby mission with free return to Earth one year later. Three 30-day Earth departure seasons between 1972 and 1975 were identified. The season-open trajectory for earth departure on 4 April 1972 is developed in detail for this presentation.

  • Cost: Free for presentation only. Membership not required.
  • Meal option prices (order by Wednesday, Jan. 25, 2017, 2:00 PM): Members $12, Non-members $15
  • Meal: Red River BBQ; brisket, spicy links, cole slaw, beans, iced tea. Vegetarian options available.

Economics of Asteroid Mining, by Shen Ge
Asteroid mining is drawing increasing interest with the establishment of two space companies in 2012 publicly declaring their intention of mining asteroids. However, the economics model necessary to analyze the feasibility of asteroid mining initiatives has not advanced in the last decade which presents a significant challenge for these companies and future startups to attract significant investment for such capital projects. Specifically, no significant additions have been added to Mark Sonter’s net present value equation for asteroid mining since his thesis was published in 1997. This presentation serves to address both the technical and economic factors required to determine a future asteroid mining mission’s feasibility. Building upon the Sonter equation, the Ge-Satak equation introduces new variables to cover the gaps and resolves uncertainties in the previous equation.
