System Concept Studies Will Aid NASA in Asteroid Redirect Mission

SSL 1300 commercial satellite bus Space Systems/Loral Palo Alto, CA 650-852-4000 www.sslmda.com NASA continues to advance the journey to Mars through progress on the Asteroid Redirect Mission (ARM), which will test a number of new capabilities needed for future human expeditions to deep space, including to Mars. This includes advanced Solar Electric Propulsion — an efficient way to move heavy cargo using solar power, which could help pre-position cargo for future human missions to the Red Planet.

3D Vision System Aids 560-Mile Piloted Drive

Audi completed a long-distance test drive of its Audi A7 Sportback semi-autonomous concept vehicle, finishing the journey at the International CES 2015 consumer electronics show in Las Vegas. The “piloted driving” — Audi’s take on combining autonomous driving with individual control — began in Stanford, California and ended two days and 560 miles later on January 6, 2015.

Google Glass for Industrial Automation

A new concept uses Google Glass for operating machinery, with all of the benefits delivered by wearable computing in an industrial environment. With Google’s Web-enabled glasses, status or dialog messages can be projected via a head-up display directly into a person’s field of vision. Online information and communication is also possible with this innovative device, and error messages can be acknowledged using a touchpad.

Energy Efficiency in Machine Tools

Discussions of the efficient use of energy have become more frequent in many sectors of industry. Machine tools comprise numerous motors and auxiliary components whose energy consumption can vary strongly during machining. The main spindle drive, for example, and the coolant system work near their rated power during roughing with a high stock removal rate, while the power consumption during finishing is significantly lower. There is a very close interdependence between the individual components and subassemblies of a machine tool and aspects of productivity and quality. From a detailed examination of manufacturing processes to the power consumption of individual components, potential for savings can be evaluated and measures can be defined for the efficient use of energy.

NASA Robot Explores Volcanoes

Carolyn Parcheta, a NASA postdoctoral fellow based at NASA's Jet Propulsion Laboratory in Pasadena, California, and JPL robotics researcher Aaron Parness are developing robots that can explore volcanic fissures."We don't know exactly how volcanoes erupt. We have models but they are all very, very simplified. This project aims to help make those models more realistic," Parcheta said.Parcheta, Parness, and JPL co-advisor Karl Mitchell first explored this idea last year using a two-wheeled robot they call VolcanoBot 1, with a length of 12 inches (30 centimeters) and 6.7-inch (17-centimeter) wheels.VolcanoBot 2, smaller and lighter than its predecessor, will explore Hawaii's Kilauea volcano in March 2015. Parcheta's research endeavors were recently honored in National Geographic’s Expedition Granted campaign.

NASA Advances Next-Generation 3D-Imaging Lidar

Building, fixing, and refueling space-based assets or rendezvousing with a comet or asteroid will require a robotic vehicle and a super-precise, high-resolution 3D imaging lidar that will generate real-time images needed to guide the vehicle to a target traveling at thousands of miles per hour. A team at NASA’s Goddard Space Flight Center is developing a next-generation 3D scanning lidar — dubbed the Goddard Reconfiguable Solid-state Scanning Lidar (GRSSLi) — that could provide the imagery needed to execute these orbital dances. GRSSLi is a small, low-cost, low-weight platform capable of centimeter-level resolution over a range of distances, from meters to kilometers. Equipped with a low-power, eye-safe laser; a MEMS scanner; and a single photodetector, GRSSLi will "paint" a scene with the scanning laser, and its detector will sense the reflected light to create a high-resolution 3D image at kilometer distances. A non-scanning version of GRSSLi would be ideal for close approaches to asteroids. It would employ a flash lidar, which doesn’t paint a scene with a mechanical scanner, but rather illuminates the target with a single pulse of laser light — much like a camera flash. Source:
