5 days ago So this article is right up to date including all links. This composite material strength allows military drones to cruise at extremely high . which send commands to the physical components in the aircraft or remote controller. Military efforts to approve the flying of Predator military drones tech world meets the hard and unforgiving laws of aviation – and of physics. Military commanders use tactics and strategy in combat to inflict as much damage on the enemy while trying to risk as few personnel and resources as possible.

LiDAR scanned the topography of the main vent and a thermal camera recorded temperatures at cracks and hot springs.

Because Lev and her colleagues visited the volcano not long after it erupted, the lava flow was still unstable and hot. Christopher Zappa, a Lamont associate research professor, specializes in ocean and climate physics. In the marginalized zones transition zones between open ocean and sea ice of the Arctic and in the tropics, he studies how the atmosphere generates waves through wind, how waves break, and how that energy injected into the ocean affects the transfer of gases, heat and energy between the ocean and the atmosphere.

Zappa uses large fixed wing drones with wingspans of 10 to 12 feet and 5 to 6-foot fuselages. These sophisticated unmanned aerial systems that can fly up to 24 hours and carry payloads of 10 lbs, require two ground crew, two flight crew and a lot of technical expertise.

Alessio Rovere Zappa developed six payloads for drones, miniaturizing technology that he previously used on ships or manned aircraft: Infrared imaging tells the temperature of any surface, whether ocean, ice or land. The temperature maps help determine rates of exchange between the ocean and atmosphere; the stages of ice growth, melt or refreezing; the temperature of the meltwater relative to ocean water and how sea ice drifts. Visible hyperspectral camera can show when ice breaks up and sunlight penetrates, which can influence when phytoplankton blooms occur.

Since phytoplankton absorbs solar radiation, this may lead to more ocean heat close to the surface, which can affect ice melt.

Near infrared hyperspectral imaging shows surface properties, and can reveal the ages of sea ice. Meteorological turbulent fluxes measures fluxes of momentum, heat and water vapor over the ocean.

This payload also includes LiDAR which can measure ocean waves that break up the ice, and determine how much ice lies out of the water and how thick is is. Drone deployed micro-drifter is a soda-can-sized pod ejected from the drone. As it falls, it analyzes the atmosphere for temperature, water vapor and pressure.

In the ocean, it becomes a micro-buoy and measures the temperature and salinity of the ocean surface at different depths. The pod conveys atmospheric information in real time back to the drone where it is stored.

The ocean data is kept onboard the micro-pod; once it sees the drone, it transmits the information. Zappa is currently developing sea ice radar that will measure sea ice thickness. One thing drones allow us to do is get away from these superstructures that may or may not affect the environment," said Zappa.

So for me, it's critical to get away from the ship or look at areas undisturbed by the ship, both in the atmospheric side and the ocean side. Drones allow me to do this very nicely. Most air pollution data comes from ground measurements, but drones will enable the scientists to gather data about pollution at different altitudes to study how pollutants disperse in the environment. Without a drone, it would be difficult and dangerous to gather this kind of information.

Prescribed fires, traditionally done by hand or helicopter, help eradicate invasive species and control wildfires by safely getting rid of excess vegetation that might otherwise catch fire.

As the drone flies, the balls of ignition material are injected with alcohol then dropped to the ground. Seconds later, they burst into flames.


They can be dropped in a straight line or in a particular pattern in areas that might be too dangerous or difficult to access in other ways. A stitched aerial picture. Flying close to crops, the drone uses a 2-D laser scanner to estimate crop height. Scientists here are also developing a drone that can pick leaves off crops so that they can be analyzed for crop health or to determine the identity of a weed. The Nebraska lab's drone-mounted water sampling system can monitor water quality, locate toxic algae and find invasive species in hard to access areas.

The drone uses a one-meter long tube to suck up water as it flies over the water body. The water is stored in vials on the drone and is measured for temperature and salinity.

Some day drones could potentially carry miniaturized genetic sequencing instruments that would enable them to analyze the DNA in the samples to identify disease, and endangered or invasive species. NIMBUS is also working on a drone that can fly to a remote sensor, determine if its battery needs to be recharged and wirelessly recharge it. Since drones could do this repeatedly, they can keep all sensors operating continuously so no data is lost.

Scientists are also exploring a drone that can retrieve data from underwater ocean sensors that are able to surface. He would one day like drones to be able to fly over the ocean and measure atmospheric gases with precision.

I came at this topic as a media scholar who had studied war, media, and satellites in the past … and I was not satisfied with the existing media theories that were available. Drones, just by moving over an area, are [altering] life on Earth, reorganizing where and how people move, what their disposition is or what their feeling is about the sky above them — and who they want to be around and who they try to avoid.

When drones are operating in an area over time, above a certain region, they change the status of sites and motions on the ground. But how different are drones from previous military tools? We had video game-like imagery from Gulf War inand there have been aerial bombing campaigns throughout the 20th century, which also altered how people act on the ground.

In the book we try to make clear that current forms of drone warfare are part of a longer history of aerial militarization, that this is not unique to the era of the drone. One chapter of the book, for instance, focuses on drone experiments during World War II.

One of the most distinguishing aspects of drone use is that they have been mobilized to fight wars without public deliberation.

Drones are being used right now, not just for warfare but for patrolling, [which] is a sign of how available they are to be mobilized. Some critics align the drone with a kind of totalitarian tendency. We see a lot of that here at MIT. I never think a technology is just one thing. A lot of people are trying to design drones to do good things.
