Aerocapture Mission Concepts for Titan and Venus Exploration
(Georgia Institute of Technology, 2008-06-24)Aerocapture has been studied for decades as a mass-efficient way to deliver orbiting spacecraft to planets or moons that have atmospheres. NASA's In-Space Propulsion Technology (ISPT) program sponsored detailed studies ... -
Aerocapture Technology Developments by the In-Space Propulsion Technology Program
(Georgia Institute of Technology, 2008-06-26)This paper will explain the investment strategy, the role of detailed systems analysis, and the hardware and modeling developments that have resulted from the past 5 years of work under NASA's In-Space Propulsion Technology ... -
Analysis of Temperature-Constrained Ballute Aerocapture for High-Mass Mars Payloads
(Georgia Institute of Technology, 2008-06-25)We investigate trajectories and heating environments of ballute-assisted, low- to high-mass Mars aerocapture systems. Ballutes permit aerocapture at higher altitudes and allow for lower thermal protection system (TPS) ... -
Antenna Elements Integrated into the Parachutes of Planetary Entry Probes
(Georgia Institute of Technology, 2008-06-25)The canopy of the parachutes of planetary entry probes may be used to integrate elements of the antennas in charge of the communications with the orbiter spacecraft during the descent. The additional surface provided by ... -
Arc-Jet Simulations of Ablators for the Mars Science Laboratory Program
(Georgia Institute of Technology, 2008-06-25)The NASA Ames team working with the Mars Science Laboratory (MSL) project has recently been involved in arc-jet tests to characterize the material response of candidate ablators to the high heat flux and high shear stress ... -
Assessment of PWT Conditions for the STARDUST Post-Flight Evaluation
(Georgia Institute of Technology, 2008-06-25)On January 15th 2006, the STARDUST capsule re-entered Earth's atmosphere after its almost seven year journey with a re-entry speed of 12.8 km/s. Due to the nature of the mission, no diagnostics for the re-entry phase ... -
Atromos: Mars Companion Mission, Mid Sized Polar Lander Investigation
(Georgia Institute of Technology, 2008-06-24)The polar regions of Mars offer a rich environment to search for signs of life. The Atromos probe was designed with the intent of investigating this polar region for evidence of life and to take atmospheric data in the ... -
Autorotating Pararotor Decelerator Technology for Miniature Atmospheric Entry Probes
(Georgia Institute of Technology, 2008-06-24)Research has been conducted on the feasibility and modeling of a pararotor decelerator platform for atmospheric and planetary science as part of a masters degree in Mechanical Engineering at the University of Idaho. The ... -
Avionics Architectures and Components for Planetary Entry Probe Payloads and Systems
(Georgia Institute of Technology, 2008-06-25)Like all complex spacecraft, planetary entry probes require reliable, performant and resource-efficient avionics to successfully fulfil their mission. Due to specific mission constraints and targets, high integration as ... -
