Cold Atom Laboratory (CAL) is a multi-user facility that will provide the ability to study ultra-cold quantum gases in a microgravity environment. The laboratory is an internal payload that will operate on the International Space Station (ISS) in 2016. Principal Investigators from various universities will trade off in designing experiment sequences that(More)
The Mars Ascent Vehicle (MAV) is a critical mission element of the Mars Sample Return campaign that delivers the Martian sample from Mars surface to orbit for rendezvous with retrieving spacecraft and sample return to earth. The MAV design presents significant challenges in that it must fit in the Lander mission architecture, have a minimized total system(More)
A Mars Ascent Vehicle (MAV) systems engineering study is underway to define the driving requirements, concept of operations, system engineering challenges, and surface support systems to enable the launch of a rock core sample to a specified delivery orbit for later retrieval and return to Earth. The proposed MAV would essentially be a small-scale launch(More)
The Nuclear Electric Xenon Ion System ion thruster was developed for potential outer planet robotic missions using nuclear electric propulsion (NEP). This engine was designed to operate at power levels ranging from 13 to 28 kW at specific impulses of 6000-8500 s and for burn times of up to 10 years. State-of-the-art performance and life assessment tools(More)
In 2010 the Mars Science Laboratory (MSL) mission will deliver NASA's largest and most capable rover to the surface of Mars. MSL will explore previously unattainable landing sites due to the implementation of a high precision Entry, Descent, and Landing (EDL) system. The Parachute Decelerator System (PDS) is an integral part of the EDL system, providing a(More)
The Mars Science Laboratory (MSL) Mission will land a 900-kg rover on the surface of Mars in 2010. Four Mars Lander Engines (MLE's) will be fired during the final propulsive descent to maintain a 0.75 m/s vertical rate of descent, in support of a tethered landing approach referred to as the “Sky-Crane”. At 20 m above the surface the rover will(More)
In 2010 the Mars Science Laboratory (MSL) Mission will deliver the most massive and scientifically capable rover to the surface of Mars. To deliver this payload, an aerodynamic decelerator is required to decelerate the entry vehicle from supersonic to subsonic speeds, in advance of propulsive descent and touchdown on Mars. The aerodynamic deceleration will(More)
Mars Science Laboratory is a scientific mission to the surface of Mars that would include a rover with 10 science instruments. In order to accomplish this mission, the rover must be transported from Earth to the Martian surface. The mechanical hardware that transports the rover is developed by the cruise, entry, descent, and landing (CEDL) mechanical(More)
This paper describes a system architecture for an aerobot blimp guiding and controlling a herd of sondes on Titan's surface. Options for inertial navigation are proposed that make use of a direct communication link to Earth. A potential field controller is used for autonomous tracking of terrain features on the surface, and hazard avoidance. The result of(More)
There have been numerous NASA and international orbiters, atmospheric probes, and landers that have explored Venus over the past 50 years. The Russian Space Agency (RSA) conducted over twenty missions to Venus from the 1960's to 1980's, including flybys, entry probes, landers and orbiters. NASA's first measurements of Venus came from a flyby of the Mariner(More)
