Thomas Harrison, a group leader at Oak Ridge National Laboratory, will give an overview this evening of the work that ORNL performs for NASA’s space nuclear thermal propulsion (NTP) program, a press release said.

ORNL performs research on materials, fuels, instrumentation and control components and techniques, and systems analysis, all of which are vital to the successful deployment of NTP, the press release said. Harrison will also describe some of the challenges facing the technology and the methods that ORNL researchers are using to overcome them.

Harrison is currently the Advanced Nuclear System Safety and Licensing Group Leader at ORNL, the press release said. [Read more…]

An eight-foot-tall telescope with an 18-inch diameter lens has been donated for use at Roane State Community College’s Tamke-Allan Observatory, and it offers the clearest views yet of the universe’s distant reaches.

Like the two powerful telescopes already in place at the observatory, the latest telescope is a donation, this time from former long-time Alaska resident and avid amateur astronomer John Jaruzel, who now calls Oak Ridge home.

“It is by far the most powerful telescope (at Tamke-Allan) in terms of collecting light,” said David Fields, director of the observatory. “This scope will enable the viewer to see extremely dim stars and objects,” he said.

“This is a wonderful thing to be able to offer the students views of such distant celestial objects,” Fields said of the gift. “It’s inspiring.”

Tamke-Allan Observatory at Roane State Community College continues its Summer Public Stargazing with an examination of light and light pollution on Saturday, August 3.

The gates open at 7:30 p.m. Saturday, and a public lecture will be presented at 8 p.m. by guest lecturer and retired clinical researcher Linda Fippin.

“For the vast majority of human history, nighttime lighting was limited to the hearth fire,” a press release said. “As villages, towns, and eventually cities developed, lighting was still limited to oil lamps and candles. Gas lighting was not invented until the late 18th century, and electric street lights have only been in use for about 140 years. Nighttime lighting has many benefits, but excessive and inappropriate use has led to light pollution, which not only has negative effects on people, quality of life, and the natural environment, but also wastes energy resources. This talk will cover a brief history of nighttime lighting, the effects of light pollution, and what can be done to lessen them.”

Tamke-Allan Observatory will begin its summer public stargazing with a 50th anniversary celebration of the Apollo 11 moon landing on Saturday, July 6. The gates will open at 7:30 p.m., and a public lecture will be presented at 8 p.m. by guest lecturer Julie Rhyne, a press release said.

July marks the 50th anniversary of landing humans on the moon, the press release said. NASA’s Project Apollo, the program developed to land people on the moon, represented the “remarkable efforts of engineers, scientists, and many various industries around the country working together to accomplish one of the greatest feats in human history,” the press release said.

It said the July 6 presentation will provide an overview of the spacecraft and the Apollo missions. There will be pictures and memorabilia, moon globes, and hands-on learning about the Saturn V rocket that launched men to the moon, the release said.

State certifies four new adventure tourism districts in Roane

Adventure tourism is one of the hottest industries in the country and the world. To capitalize on this growing trend, Tennessee passed the Tennessee Adventure Tourism and Rural Development Act of 2011 in hopes to incentivize adventure tourism businesses to invest and create jobs in districts planned all across the state.

Tennessee’s abundance of natural resources makes it an ideal setting to support this segment of the tourism industry. The act allows qualified businesses that locate within a certified district to earn a jobs tax credit to offset a portion of the business’ Tennessee franchise and excise tax liability. Qualified businesses may include restaurants, hotels, or other tourist related attractions.

“I began the process in February and over the next few months required resolutions from each of the cities where the district resides, as well as the county. They all passed unanimously,” said Pam May, vice president of The Roane Alliance. “Roane County has so many natural resources ideal for adventure tourism—more than 700 miles of shoreline, bluffs, and vistas on the plateau, and a large number of Wildlife Management Areas—just to name a few.” [Read more…]
