NASA Rocket to Create Clouds
By Clara Moskowitz | Space.com
A rocket experiment set to launch Tuesday aims to create artificial clouds at the outermost layers of Earth's atmosphere.
The project, called the Charged Aerosol Release Experiment (CARE), plans to trigger cloud formation around the rocket's exhaust particles. The clouds are intended to simulate naturally-occurring phenomena called noctilucent clouds, which are the highest clouds in the atmosphere.

"This is really essentially at the boundary of space," said Wayne Scales, a scientist at Virginia Tech who will use computer models to study the physics of the artificial dust cloud as it's released. "Nothing like this has been done before and that's why everybody's really excited about it."
The experiment is the first attempt to create artificial noctilucent clouds. A previous spacecraft, called Aeronomy of Ice in the Mesosphere (AIM), launched in 2007 to observe the natural clouds from space.
CARE is slated to launch Tuesday between 7:30 and 7:57 p.m. EDT (2330 and 2357 GMT) from NASA's Wallops Flight Facility in Virginia.
Noctilucent means "night shining" in Latin. Although difficult to spot with the naked eye, the clouds are best visible when Earth's surface is in darkness and sunlight from below the horizon illuminates the high-altitude clouds.

These clouds, also known as polar mesospheric clouds, are made of ice crystals. The natural ones tend to hover around 50 to 55 miles (80 to 90 km) above the Earth. CARE will release its dust particles a bit higher than that, then let them settle back down to a lower altitude.
"What the CARE experiment hopes to do is to create an artificial dust layer," Scales told SPACE.com. "Hopefully it's a creation in a controlled sense, which will allow scientists to study different aspects of it, the turbulence generated on the inside, the distribution of dust particles and such."
CARE is a project of the Naval Research Laboratory and the Department of Defense Space Test Program. The spacecraft will launch aboard a NASA four-stage Black Brant XII suborbital sounding rocket.
Scientists will study its progress from ground based instruments as well as the STP/NRL STPSat-1 spacecraft in Earth orbit. Researchers will track the CARE dust cloud for days or even months to study its behavior and development over time.
Because the optical observations are crucial, the launch can only take place if the weather is clear both at the launch site and at multiple observation stations along the Atlantic coast and in Bermuda.
If CARE cannot launch Tuesday, the team can try again between Sept. 16 and Sept. 20.

Estonia must accept African & Middle Eastern immigrants says politician
Kalle Laanet, an Estonian politician, spoke at the International Migration Forum held in Tallinn. He told the audience that the question is not: Should Estonia take the African and the Middle Eastern immigrants (who illegally entered Southern Europe)? He said the question is: How will Estonia take the immigrants?

Rescuing Palmyra: History's lesson in how to save artefacts
With Islamic State militants now inside the historic town of Palmyra in Syria, the question, inevitably, is whether they will destroy the ancient ruins.
As IS continues to sweep through parts of Iraq and Syria, damage to centuries-old artefacts - because IS sees statues and shrines as idolatrous - is plentiful.
But history has shown that, when culturally important sites are under ...

Since the 1970s, Saudi Arabia has actively spread its interpretation of Islam, Wahhabism or Salafism, worldwide. It is the most literal version of Islam and affects many young Muslims, who regard society as a place to Islamize, writes social anthropologist Aje Carlbom.
