Unit Test 2 Group B Higt note ПОМОГИТЕ!!!READING!!!Drones in Space
The last few years have seen massive developments in drone technology and drones have become a familiar part
of our lives. People use them in climate monitoring, rescue, and amateur photography. When you think about it, space exploration seems a logical next step! In fact, NASA and other space agencies have already started to develop drones for this purpose.
Special challenges
Conditions on other planets are very different to those on Earth. With no atmosphere around other planets, it is very important to decide on the correct weight of the flying drones. If they are too heavy, they won’t be able to get into the air; if they are too light they will be difficult to control. Drones won’t have the usual rotor blades which they currently have. Instead, technicians have been experimenting with models that use gas or water jets to get into the air and fly around.
NASA admits that controlling the drones will also be difficult because the remote control devices some of us are familiar with won’t work in space. Instead, scientists plan to program the drones so that they can collect information on their own. Scientists have also been developing lightweight solar batteries so that drones can use this source of energy when sunlight is available.
In other ways, the drones will look like the ones we know: they will be about the same size and shape. There will be
a camera underneath, pointing downwards to take pictures of the surface. One day a drone might take a picture of something nobody has ever seen.
A range of applications
As humans explore solar system and galaxies beyond,
there are many ways drones can help. During such exploration, safety is one of the most important things for space agencies to think about. Astronauts will need to train a lot so they can learn to avoid getting into danger on the surfaces of planets and asteroids. Drones could be used
to identify the most extreme conditions by collecting information about the air, temperature, pressure and other factors. They could also identify the safest ways to move around. At the same time as this, drones can also find possible locations to build. Imagine living on Mars! There are already plans to establish colonies there after 2020!
