"We are going to modify the process we ran on Sol 60 to acquire another icy sample and attempt to deliver it to TEGA," the Thermal and Evolved-Gas Analyzer, said Barry Goldstein, Phoenix project manager from NASA's Jet Propulsion Laboratory in Pasadena, Calif. "We will repeat what we did successfully with small modifications to adjust for what we learned."
The Sol 60 effort on July 26 by Phoenix successfully obtained a sample by rasping 16 holes into and scraping the work trench informally named "Snow White." Most of the sticky Martian soil adhered to the scoop even after the scoop was tipped and the rasp activated to help sprinkle soil into TEGA.
The revised plan includes reducing the length of time the rasp operates as it makes the holes in the trench to reduce any potential heating of the sample, and for increasing the number of times the scoop is vibrated during the sample delivery action.
Images received Sunday morning showed the soil collected on Sol 60 had fallen out of the scoop, which had been left inverted over the lander's deck.
The Phoenix mission is led by Peter Smith of the University of Arizona with project management at JPL and development partnership at Lockheed Martin, Denver. International contributions come from the Canadian Space Agency; the University of Neuchatel; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
