We would like to change this situation, by developing program verification techniques that are available to a larger audience. Other work areas include theorem proving and model checking. She is well-known for her work on program verification of concurrent software. Java, and he was part of the RAISE project (Rigorous Approach to Industrial Software Engineering) which developed the RSL wide spectrum specification language. Please refresh the page and try again. At 7.7-feet by 4.7-feet (2.4 meters by 1.9 meters), the LADEE spacecraft would be dwarfed by comparison to the car-sized 1 ton Mars Curiosity rover. His research interests cover formal design of real-time, embedded and hybrid systems, program verification, concurrent computation models, modal and temporal logics, and so on. + See Viewing Options could be introduced to high school students in a classroom situation. You will receive a verification email shortly. Thank you for signing up to Space. The last human visitor left the Moon in December 1972. http://www.nasa.gov/mission_pages/LADEE/main/. ... Ranger Block I Design (Rangers 1 and 2) This is a computer-rendered image of Cassini during the Saturn Orbit Insertion (SOI) maneuver, just after the main engine has begun firing. Space calendar 2020: Rocket launches, sky events, missions & more! The spacecraft is tasked with a good deal of lunar science investigations, set to explore the moon's atmosphere and dust during its 100 days of science. Klaus Havelund is a Senior Research Scientist at the Laboratory for Reliable Software (LaRS), Jet Propulsion Laboratory (JPL), California Institute of Technology. Moreover, we also outline how program verification in Snap! Phobos and Deimos, the moons of Mars, are seen in this movie put together from 19 images taken by Mars Odyssey's camera. This graphic illustrates Cassini's trajectory, or flight path, during the final two phases of its mission. He has worked with formal methods more than 3 decades, and at NASA for more than two decades. Water on the moon is more common than we thought, studies reveal. With the progress in deductive program verification research, new tools and techniques have become available to reason about non-trivial programs written in widely-used programming languages. Spacecraft: The LADEE spacecraft bus design was derived from the MCSB (Modular Common Spacecraft Bus), architecture developed at NASA/ARC (Ames Research Center) from 2006-2008.

Receive mail from us on behalf of our trusted partners or sponsors? Marieke Huisman is a professor in Software Reliability at the University of Twente, leading the Formal Methods and Tools group. The Cassini spacecraft views Saturn with a selection of its moons in varying sizes. NASA scientists have identified a molecule in Titan’s atmosphere that has never been detected in any other atmosphere. SpaceX just launched its 100th successful Falcon rocket flight.

The base angle is chosen so that the resultant reaction wheel torques are mostly along the spacecraft’s Z … A thorough understanding of these influences will help researchers predict how future lunar exploration may shape the moon’s environment and how the environment may affect future explorers.

© “The LADEE mission represents an exciting opportunity to build the first low-cost, small satellite in-house at Ames in more than 30 years,” said Butler Hine, LADEE project manager. Spacecraft: The LADEE spacecraft bus design was derived from the MCSB (Modular Common Spacecraft Bus), architecture developed at NASA/ARC (Ames Research Center) from 2006-2008. programs. NASA engineers expect this design will enable many future, low-cost inter-planetary missions.

This animation glides along the shoreline of Ontario Lacus, the largest lake on the southern hemisphere of Saturn’s moon Titan. LADEE’s communications system uses a modular design featuring a central Interface/Power Controller that distributes electrical power to the individual components.

This antenna … New York, He is known for his earlier work on the Java PathFinder model checker for Artist's concept of our solar system showing a sense of scale and distance. Educator-astronaut talks to 'kids at heart' for online talk Tuesday.
