NASA selects new teams to study Moon asteroids

first_imgWashington: The US space agency NASA has selected eight new research teams to collaborate on research about the Moon, near Earth asteroids, and the Martian moons Phobos and Deimos and their near space environments. The Solar System Exploration Research Virtual Institute (SSERVI) will support the new teams for five years at a combined total of about USD 10.5 million per year, funded by NASA’s Science and Human Exploration and Operations Mission Directorates, NASA said in a statement.

Eight SSERVI teams were selected via peer review from a pool of 24 competitive proposals, according to the statement. One such team, led by Rosemary Killen at NASA’s Goddard Space Flight Center in Maryland, will focus on plasma interactions with airless bodies and determine the effects of the space environment on robotic and human assets at various geographic locations on the Moon. The team also will model the radiation environments and related effects associated with space exploration.

It will assess the quantity and availability of resources on the Moon, test the technology required for processing those resources, and field test the concepts of operations required for sustained human lunar presence. “We are extremely pleased that the community responded with such high-quality proposals, and look forward to the many contributions new SSERVI team members will make in addressing NASA’s science and exploration goals,” said Greg Schmidt, SSERVI’s director at Ames.last_img read more

PT Timah to order more large dredges for tin mining

first_imgState-controlled Indonesian tin producer PT Timah plans to order two new generation dredges worth around $100 million this year, the Antara news agency has reported. Timah is gradually upgrading its dredge fleet, replacing its old bucket ladder dredges by either the new deep water vessels or smaller lower cost cutter suction ones. It a recent presentation the company said that its offshore tin mining leases contained resources of an estimated 649,402 t of tin, of which 217,549 t were Proven and Probable reserves. Timah’s offshore operations produced 20,444 t of tin-in-concentrate in 2010, although production in 2011 is expected to have declined.The two bucketwheel dredges being ordered this year are due to be operational in 2014 said Wachid Usman, Timah’s President Director, adding to another dredge of the same type which is planned to be in operation in 2013.The company’s corporate secretary Abrun Abubakar said Timah has set capital expenditure at $222 million this year to finance the purchases of the dredges. Abrun said part of the capital spending will also be used for its Mentok tin smelter on Bangka island.last_img read more
