Guatemala: Probing reports drug lord may be dead

GUATEMALA CITY (AP) ? Guatemalan authorities are mobilizing security forces to scour a remote, rural area where residents reported a gunbattle between drug gangs and said one of the dead resembled Mexico's most-wanted drug lord, Joaquin "El Chapo" Guzman.

But officials stressed late Thursday that they had not yet found any bodies or even confirmed a shootout happened.

Interior Minister Mauricio Lopez Bonilla told The Associated Press that police and soldiers would begin searching on foot and in the air at first light Friday, looking for the scene of the reported gunfight in Peten province near the border with Mexico.

Authorities initially said Thursday night that they were investigating whether Guzman was one of at least two men killed in the remote area, but hours later backtracked and said they had only received reports of a battle from local people.

Government spokesman Francisco Cuevas first told Guatevision Television that two drug gangs had clashed in Peten, an area that has seen an increase in drug violence and that at least two men had died in the shootout.

"We have to wait for all the technical information in order to determine if, in fact, one of the dead is of Joaquin 'El Chapo' Guzman," Cuevas said.

Later, Cuevas told Mexico's Televisa network that authorities hadn't yet found a body or the scene where reports said a shootout took place.

He never said what led officials to think that one of the dead men might be Guzman.

But Interior Department spokeswoman Carla Herrera told The Associated Press that one of the victims physically resembled the drug lord. She said officials had asked the Mexican government to send Guzman's fingerprints to compare them to the man found inside a vehicle and to send investigators.

However, Herrera's boss, Lopez Bonilla, told the AP that it was residents of the town of San Francisco who had told officials of a gunbattle and reported that one of the people killed looked like Guzman.

"The fact is we don't have any of this information confirmed," Lopez Bonilla said.

Mexican President Enrique Pena Nieto said late Thursday that he had no information on the case.

"I don't have any information that can confirm that," he told reporters.

Peten province is an isolated area of jungle and ranches where 27 ranch workers were massacred in 2011 by the Zetas drug gang, a top rival for Guzman's Sinaloa drug cartel.

Guzman, who has been in hiding since escaping from a Mexican prison in a laundry cart in 2001, is one of the world's most dangerous and most wanted fugitives.

He's also one of the richest: Forbes magazine has estimated his fortune at $1 billion.

New video brings Webb Telescope's third mirror to light

Feb. 1, 2013 ? There are four types of mirrors that will fly on NASA's James Webb Space Telescope. They're called the "primary, secondary, tertiary" and fine steering mirrors. Although the 18 primary mirror segments make the biggest splash, the other mirrors are equally as important. A new video takes viewers behind the scenes for a special look at the tertiary mirror.

The video called, "Third Light's the Charm" is part of an on-going video series about the Webb telescope called "Behind the Webb" (http://webbtelescope.org/webb_telescope/behind_the_webb/17). The video, produced by Mary Estacion from the Space Telescope Science Institute (STScI) in Baltimore, Md., takes viewers behind the scenes with scientists and engineers who are creating the Webb telescope's components.

The 2 minute, 41 second video takes viewers to Ball Aerospace in Boulder, Colo., where Koby Smith, Aft Optics Subsystem Integrated Product Team lead, explains how light is manipulated with the Webb mirrors to get a clearer understanding of the object being focused upon.

There are 18 hexagonal mirror segments that, when combined, make up the large primary mirror with a collecting area of 25 meters squared (269.1 square feet).The secondary mirror is perfectly rounded and convex, so the reflective surface bulges toward the light source. The tertiary mirror is the third stop for light coming into the telescope and is the only fixed mirror in the system -- all of the other mirrors align to it.

"The tertiary mirror is approximately a meter wide and is designed to accept the light from many field points and relay them through the fine steering mirror to the instruments," said Lee Feinberg, NASA Optical Telescope Element Manager for the Webb telescope at NASA's Goddard Space Flight Center in Greenbelt, Md.

Smith explained, "The light from an object reflects off the primary mirror, the secondary mirror, into the Aft Optics Subsystem's aperture, and off the tertiary and fine steering mirrors, before entering the science instruments in the back of the telescope." The Aft Optics Subsystem sits in the middle of all of those mirrors.

All the mirrors are made of a light metal called beryllium which is very strong for its weight and holds its shape across a range of temperatures.

Estacion also takes viewers into the optical test tent within a clean room for a look at the tertiary mirror. She and Smith explain the process it still needs to go through to be ready for flight on the Webb telescope.

The optical test tent is used for testing the secondary and tertiary mirrors. Smith shows viewers an interferometer that's used to measure the surface quality of the optics. It sends out a wavefront of light and compares it to a known reference, and any deviations on that surface will appear as fringes on a camera screen.

Estacion explains that there are more steps in the preparation of the tertiary mirror including vibration and thermal testing before being integrated with the rest of the telescope.

The James Webb Space Telescope will be the world's next-generation space observatory and successor to the Hubble Space Telescope. As the most powerful space telescope ever built, Webb will observe the most distant objects in the universe, provide images of the first galaxies ever formed and see unexplored planets around distant stars. The Webb telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

The "Behind the Webb" video series is available in HQ, large and small Quicktime formats, HD, Large and Small WMV formats, and HD, Large and Small Xvid formats.
