Parametric Co-Optimization of Lifting Blunt Body Vehicle Concepts for Atmospheric Entry
The selected proposals for unique, disruptive or transformational space technologies will investigate challenges in the areas of solar cell operations at high temperatures, atmospheric entry model development, synthetic biology applications for space exploration and dynamic tensegrity-based space structures.
Proposed concepts should indicate uses for ejectable mass up to 150 kg prior to Mars atmospheric entry and/or another 150 kg during the entry and landing phases of the mission.
Quadrantids are, like the Geminids, relatively slow meteors, with an atmospheric entry velocity of 42 km/sec.
The crew has also performed a "hotfire" its thruster jets to ensure they can steer the shuttle to its entry point ahead of its atmospheric entry.
Ultimately, if the MarCO demonstration mission succeeds, it could allow for a "bring-your-own" communications relay option for use by future Mars missions in the critical few minutes between Martian atmospheric entry and touchdown.
NASA missions rely on computational simulations to predict conditions a spacecraft may experience during atmospheric entry on other planets -- calculations that help experts decide the type and thickness of materials used to make thermal protection systems for spacecraft.
Other topics could include optical communication for space using integrated photonics, atmospheric entry modeling development using data from the first flight test of NASA's Orion spacecraft in December 2014, and high voltage power management and distribution electronics for space applications.
Taurids can appear particularly impressive because of their slow atmospheric entry velocity (27-29km/sec) and long duration in luminous flight.
The objectives of this activity shall be achieved through the following steps: - Identify and study different inflatable and deployable heatshield & hypersonic aerodynamic decelerator concepts for atmospheric entry probes, and toassess their potential benefits for potential future Mars exploration missions.
What can make Taurids appear particularly impressive is their slow atmospheric entry velocity (27-29km/sec) and long duration in luminous flight.
