5 Unearthly Powers of Satellites

There are about 3,000 satellites peering down on Earth right now. Here are a few of the incredible ways they’re making life better for us.

They stop the spread of disease

Right now, your local weather forecast alerts you when there-’s a storm approaching.
But soon, it could tell you when the next epidemic is coming, too. Many of the world’s infectious diseases are highly sensitive to fluctuations in temperature and humidity-variables that are easily tracked by satellites.

In recent years, officials in East Africa have been using satellite images to fight the spread of Rifivalley Fever, a virus that typically spreads through mosquito bites. Scientists noticed that outbreaks of the disease always follow periods of heavy rain, when mosquitoes breed rapidly. Using satellite data, they were able to analyze the region for other high-risk environmental conditions, such as warmer surface temperatures in the oceans and areas of increased vegetation. Combined with satellite weather tracking, researchers created a mapping model to predict how Rift Valley Fever could spread. So, when an outbreak of the disease occurred in Kenya in late 2006, researchers were able to correctly predict that it would move through Somalia, and they expected ‘rt to reach Tanzania. In response, public health professionals implemented procedures to prevent mosquitoes
from breeding.They also educated the public about the impending crisis. Because the people of Tanzania had an extra two to six weeks to plan ahead, it helped curb the epidemic.

They find lost cities

Thousands of years ago on the Arabian Peninsula, a city called Iram flourished.
Located at the center of the trade routes between Europe and the Middle East, Iram (also called Ubar) owed its existence to frankincense-a sweet-smelling resin that was as valuable as gold. Craftsmen in Iram made frankincense from tree sap and then exported the pricey product to Alexandria, Jerusalem, and Damascus, generating vast wealth. But according to the Qur’an, Allah was so displeased with the city’s opulence that he buried Iram under a mountain of sand.

For generations, Muslim poets and scholars wrote of |ram’s majesty, though its location was never known. In fact, no one had any idea where to look for it. In the 1970s, researchers narrowed their search to a desert in the southern Arabian Peninsula called Rub’ al Khali, but that wasn’t exactly helpful: the area is roughly the size of Texas, and it’s filled with sand dunes that can reach more than 60o feet high.

In 1992, however, members of the TransArabia Expedition actually located the lost city. Thanks to the power of satellites, they were able to detect what they suspected were old frankincense caravan routes. Then, they noticed that the presumed tracks all converged in a spot near the edge of the south» ern Arabian Peninsula. Archaeologists started digging there and soon discovered a large octagonal fortress. Further excavation of the site unearthed pottery from Greece, Rome, and Syria that was more than 4000 years old. It was official; the team had successfully located “the Atlantis of Arabia.” Researchers are optimistic that any day now, satellites could reveal the lost city of Atlantis itself.

They fights the war on drugs

Afghanistan is a troubled  LAND for many reasons. in addition to the nation’s near-constant state of war since the 19705, it also has a serious drug problem. Afghanistan is responsible for the production of more than 9o percent of the world’s illegal opiates, fueling heroin addiction across the planet. A large portion of the money generated by the illegal drug trade goes directly into the hands of terrorists-meaning the nation’s drug problem is actually an international security problem. Theoretically, it’s possible to take a huge bite out of the heroin trade by destroying the country’s poppy fields, but security forces would need to find the fields first. And because it’s too dangerous to conduct ground surveillance there, law enforcement agencies are looking to satellites for a solution.
Poppies grow quickly, undergoing three complete growth cycles per harvest season.

That speed has made it difficult for satellites to accurately detect the crop. However, scientists are currently perfecting a system that digitally catalogs every stage of the poppy life cycle so that satellites can begin to recognize the plant at each point in its growth.
The glory days of Afghanistan’s poppy fields may soon be numbered.

They provide water for the thirsty

When it comes to establishing refugee camps in times of crisis, access to clean water ls a top priority. With0ut it, water-borne diseases can spread rapidly.

After the Haiti earthquake in 2010, for example, water sources became contaminated, and a cholera outbreak further traumatized the population.Within one year, the disease had spread to an estimated 250,000 people, killing thousands. Worse still, health care workers fear that the number of infections in Haiti could double by 2012.
Now, scientists are using satellite images to ensure that a similar cholera outbreak doesn’t occur in the war-torn Darfur region of Sudan.The images assist scouts in placing refugee camps near sources of clean water.
Because the radar images can penetrate more than 50 feet below the soil, humanitarian groups can use the data to peer beneath the Earth’s surface and pick the perfect spot for a well.

They keeps cities from burning up

It’s tough to stay cool in the city. For almost 200 years, science has shown that cities are hotter than the rural areas surrounding them.The phenomenon even has a name: “the urban heat island.” But what causes it exactly? As cities become more and more developed,vegetation decreases and manmade materials start covering the land. And whereas plants have the ability to absorb heat and cool down the ground by releasing moisture, things like concrete and steel retain heat and make places hotter.

Thanks to satellites, we now have a more precise understanding of how the urban heat island works. Most satellites have the ability to measure thermal radiation, which allows scientists to track exactly how heat is distributed within a given area. That information has allowed urban planners to learn what materials -and plants- are best at staving off hot temperatures. If you’re looking to beat the heat by putting a garden on your rooftop, researchers now know that the leafy, flowering plants of the Sedum genus are the best at keeping us cool.
