United States loans three satellites, worth $1 billion, to Mexico – MEXSAT

Did you know that America had an Export-Import Bank?

 

The Export-Import Bank of the United States (Ex-Im Bank) approved a $922 million loan guarantee to support the export of three satellites and related equipment to the Mexican government for the MEXSAT regional mobile satellite system. Mexico’s Secretariat of Communications and Transportation will purchase the satellites from Boeing Space and Intelligence Systems in El Segundo, Calif. Boeing will produce two satellites with mobile service satellite (MSS) capacity and will subcontract a third satellite with fixed service satellite (FSS) capacity from Orbital Sciences Corporation in Dulles, Va.

The three satellites will be used to deploy the MEXSAT system, a next-generation, space-based communications platform that will help support social and economic development within Mexico. Various sectors will benefit from MEXSAT, including programs focusing on education, health care, disaster relief and rural telephonic service.

Mexico is one of Ex-Im Bank’s nine key markets and accounted for $8.3 billion of the Bank’s worldwide credit exposure at the end of FY 2011. In FY 2012 to date, the Bank has authorized approximately $1.8 billion in financing for U.S. exports to Mexico.

High-tech archaeologist uses radar, thermal-imagery, & UAV’s to explore sacred sites

Many Mongolians consider the tomb (of Genghis Khan) an extremely sacred place and believe any desecration of it could trigger a curse that would end the world.

“Using traditional archeological methods would be disrespectful to believers,” Albert Yu-Min Lin says. “The ability to explore in a noninvasive way lets us try to solve this ancient secret without overstepping cultural barriers.

Lin investigates sites with a high-tech tool kit that leverages photographs taken firsthand on the ground, images gathered from satellites and unmanned aircraft, GPS tracks from expeditions, and geophysical instruments. “There are many ways to look under the ground without having to touch it,” he observes. Thermal-imaging systems show what lies below by detecting heat signals and patterns emitted from the Earth. Magnetometry uses the Earth’s magnetic field to pinpoint subterranean clues as microscopic as bacteria in decaying wood. Ground-penetrating radar bounces back images revealing subsurface objects or disturbances. Tiny remote wireless sensors collect data from places no human can go.

“These new approaches could benefit all kinds of projects, from gaining a whole new view of regions like Mongolia to tracking animal migrations to mapping the brain,” notes Lin. “The real trick is synthesizing the vast amounts of information we collect into something that can be understood. My colleagues and I use visualization techniques to sort, relate, and cross-link billions of individual data bits. We program it all into a file that allows us to re-render it into a digital 3-D world.”

Hubble discovers another moon orbiting Pluto – that’s two in the last year

A team of astronomers using NASA’s Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto.

The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system.

“The moons form a series of neatly nested orbits, a bit like Russian dolls,” said team lead Mark Showalter of the SETI Institute in Mountain View, Calif.

The discovery increases the number of known moons orbiting Pluto to five.

The Pluto team is intrigued that such a small planet can have such a complex collection of satellites. The new discovery provides additional clues for unraveling how the Pluto system formed and evolved. The favored theory is that all the moons are relics of a collision between Pluto and another large Kuiper belt object billions of years ago.

The new detection will help scientists navigate NASA’s New Horizons spacecraft through the Pluto system in 2015, when it makes an historic and long-awaited high-speed flyby of the distant world.
