This paper examines final rendezvous between two vehicles in highly elliptic orbits. The range of eccentricities addressed is 0.6 to 0.9. Due to the varying orbital speeds of the two vehicles, the relative motion during elliptic rendezvous is highly

Seeking “nearby habitable worlds” was one of three science themes identified in the Astronomy Decadal Survey. Hundreds of extrasolar planets are known, but magnetic fields are likely required for these planets to be habitable. As of today, no dir

Due to Mercury's small mass and position deep within the solar gravitational well, an orbiter mission poses difficult performance requirements (i.e. ΔV, thermal extremes). However, Yen (JPL) showed that with extended trip times, substantial Mercury

The icy Jovian moon Europa is considered a top priority target by the scientific community because it appears to have the conditions necessary to harbor life. Deployable Orbiter Rover Reconnaissance Assembly (DORRA) the Europa Explorer is a conceptua

Many current manned Mars mission studies are using low lift-to-drag ratio vehicles to aerobrake at both Mars and Earth. This paper will demonstrate that if entry velocity constraints are incorporated into the interplanetary analysis of aerobraking Ma

Many current manned Mars mission studies are using low lift-to-drag ratio (L/D) vehicles to aerobrake at both Mars and Earth. The use of these low L/D vehicles could limit the allowable velocity at the atmospheric interface. This paper will demonstra

There has been a recent increase in emphasis on small satellites because of their low cost, short development times, relative simplicity, and cost efficiency. However, these satellites do have drawbacks. Their small size results in small surface area
