Looking for the origins of life on the Lake, BC

A team of scientists in the United States and Canada, certain ancient deep-sea submersible research process of rock structure behind life and explore the Lake BC jobs two remote. They are both here on Earth and in outer space, the initial form of life based on microorganisms might shed.

Researchers are very specific sedimentary formation of algae and the process is fine-turning exploration techniques to examine the origins of certain types of bacteria and formed by, and they feel may be useful for future space mission clues.

"There is life on the surface of these rocks by bacteria that are built on the Lake, called microbialites in any way," NASA's Ames Research Center, or Darlene Lim, limnologist Lake scientists, research officer in California.

"We're all trying to figure out the current in the sense that the role of these microorganisms in the sense of the past, these rocks are in the building."

About 25 million years ago until about 500 million years ago and they are very common in the early days of life on the planet microbialites remnants remain of it.

If so, an unusual amount of microbialites in Pavilion Lake and Kelly Lake is an array-like shape column artichoke in diversity.

By studying the structure, or whether a single person submersible dive scuba gear hoping to uncover these microorganisms in the researcher can be left by the sign and they might be to find chemical sometime in the distant asteroids and planets and compare.

Microbial ecology, and the project has been working with astronauts, NASA's Mike Gernhardt geochemists in Pavilion Lake, and at the end of this unique ecosystem that includes the study of Canada and Chris Hadfield

Her part is similar to NASA's space exploration for IM, "Che," as well as other sites in the High Arctic of Canada of the time spent on the main Mars simulation as a veteran of what it means.

Pavilion Lake research project, though, is somewhat unique among programs of these simulation techniques rely heavily on real-world data collection, research, researcher's exploration of the combination of a true village.

She was, in fact, this year was below the surface, and controlling the scientists of the DeepWorker submersible, she is very different, but they are sisters, Kelly Lake. Pavilion

"The Pavilion is much more depth, and water quality, clearly much much higher."

Principal investigator Darlene Lim prepares to go on a dive with the help of researcher Jeff Rozon. The Nuytco submersibles can stay underwater for up to 12 hours.Principal investigator with the help of fellow Jeff Rozon ran IM ready to go diving.

Kelly Lake shore through the control on the other hand, a lot murkier green without having to go to make a very close observation difficult.

"We had approximately 120 feet of water, even in the depths of the Paw was difficult to see," she says. "So you had to go very slow. But it is very productive when you come across something you weren't expecting and was pleasantly surprised. "

Two lakes, in a sense because they are scientifically unusual says Lim, extreme. Microbialites are found most places today or at the very very salty and alkaline. In fact, they are a few of the most inhospitable places on Earth where the survival of other creatures.

These structures were much more common on earth when im in the early era of better growth of the two paints a picture behind the microbialites in Lake, these environmental conditions.

Project to support the space agency also they future space mission logistics [NULL] might be able to learn about all the classes you are interested in.

Despite being underwater, l i m a lot around this project, technology and research protocols, says, it would need a different extreme environments of space.

"These activities, regardless of whether we'll do all the subs or scuba diver, Mars, or a month to work in the same place near Earth objects and in the future, human inference."

For example, she says, "we send humans to Mars and near-Earth objects, or communication will be delayed because of the distance you have to do and the time between the time you send them to receive them."

Pavilion Lake, they've found that the delay between the subordinate operator and allow teams to talk to them on the land, they have not been disrupted and some scientists because it seemed to allow for a better job.

However, she said, the situation in a State of emergency, or a technology project for high voltage stress not scan.

Especially now that the shuttle program was terminated in the United States is currently much uncertainty for space exploration.

However, where at least add the staging base manned NASA Pavilion Lake research project work of the mission are useless afield. Currently testing is in progress by 2025 or 2030 Orion's Mars or nearby asteroids sometime around deep space designed for a mission.

"I think we get that when you move an object close to the Earth a little bit old yourself into gear, but my son and daughter, it ll will be perfect," Lim was compounded when she smiles. feelings for the end of the shuttle program, said this summer, but also "perfumes and depressed a little excited a whole lot of expectations.

"We look to the future, but there are other options."
