Landing on Mars is difficult and not always successful. Well-designed advance testing helps. An ambitious NASA Mars rover mission set to launch in 2020 will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 12,000 mph (5.4 kilometers per second). Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed. The Mars 2020 mission will seek signs of ancient Martian life by investiga...

A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO's unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO's Extremely ...

What seemed at first like a rare instance of a huge, ancient galaxy revealed itself to be an even rarer pair of extremely massive galaxies, seen on the brink of merging when the Universe was only a billion years old. This outstanding source was first identified by ESA's Herschel space observatory, and later exposed in greater detail with the ground-based Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. The earliest galaxies in the 13.8 billion-year history of our cosmos starte...

Berkeley Lab and UC Berkeley scientists were part of a team that helped to decipher one of the most bizarre spectacles ever seen in the night sky: A supernova that refused to stop shining, remaining bright far longer than an ordinary stellar explosion. What caused the event is puzzling. A Las Cumbres Observatory press release about the supernova, which was discovered by the Palomar Transient Factory in September 2014, noted that the explosion at first appeared to be an ordinary supernova. "Se...

    Developed an ADAMS parametric rigid body dynamic model for a novel, multi-legged hopping robot named “Robotic All-Terrain Surveyor” (RATS). This conceptual robot has a spherical body, with legs equally distributed over its surface. The legs were modeled as 1-DOF actuator and oriented such that their axes of motion are normal to the surface of the body. The goal of this work was to perform design trade studies with several leg configurations (length, number and arrangement) and body sizes. Mobility, force and energy analyses were performed on these configurations to evaluate the design from a number of aspects such as controllability, mobility, and efficiency.

    The Robotics Institute, Carnegie Mellon University

    ·      Designed and implemented an optimal estimation filter (Kalman Filter) to assess the dynamic stability of off-road manned and unmanned vehicles, which can articulate significant mass. The goal of the system is to detect the onset of a tipover event through the use of inertial (accelerometers and gyros) and position (encoders) sensors.

    ·      Implemented a simulation environment to test tipover sensing. The rigid body dynamic model of the vehicle was modeled in ADAMS and it was embedded in a MATLAB/Simulink model to implement the control system. The implementation of the stability prediction algorithms was done in C/C++. This system helped in the investigation of vehicle response to operator inputs and to validate the algorithms to asses the dynamic stability of the vehicle.
