Keplero , the eye from 600 million dollars has a damaged wheel , necessary for the positioning of the four solar panels . Each 3 months, the probe must rotate 90 degrees so that the solar panels rotate toward the sun , while maintaining its precise vision on distant planets .
There will be a dramatic global decline in the number of animal and plant species in this century , if the world continues to increase beyond the measures emissions of carbon dioxide !
According to scientists if nothing is done to reduce emissions significantly in the coming decades , than half of the common plants and one third of the animals will meet to extinction .
Piante , amphibians , frogs and toads and reptiles are the groups that are likely to suffer most from climate change because of their vulnerability to rising temperatures and the inability to move quickly from one territory to. Many of these animals and plants are important because they play key “ ecosystem services ”, such as cleaning water and waste decomposition products . ” This research provides that climate change will greatly reduce species diversity , even those that are very common in most of the world.This loss of biodiversity on a global scale greatly impoverish the biosphere and the ecosystem services it provides “, ha detto Rachel Warren , della University of East Anglia, who led the research.
The image was acquired by the Japanese satellite ALOS and shows the Lighthouse Atoll in Belize Barrier Reef .
In the top center of the image you can see a dark blue circle below the sea surface : it is a circular hole baptized Great Blue Hole .
surrounded by the shallow waters of the coral reef , the Great Chasm Blue is over 300 meters in diameter with a depth of approximately 123 mt. Formed when the water level of the sea was much lower , rainwater and weather have eroded the territories exposed to their effects . Then the water came to fill the hole and cover the entire area when the sea level rose at the end of the last ice age .
image are also see two coral islands – green color due to the presence of vegetation - chiamate “ Cayes ”. The largest is to the west and is called Long Caye , while the smallest to the east was christened Half Moon Caye .
The unfavorable weather conditions over the Guiana Space Center in Kourou have forced the European Space Agency (ESA) to postpone the launch of the vector VV02.
Another launch date will be decided based on the evolution of the weather conditions in Kourou.
The autonomous region of Trentino-Alto Adige is shown in this image taken by the MERIS instrument Summer (Medium Resolution Imaging Spectrometer) aboard the Envisat satellite dell'ESA .
Il Trentino-Alto Adige ( official name Autonomous Region of Trentino-Alto Adige / SÃ¼dtirol ) is an Italian region of about 1.050.000 inhabitants with capital Trento . Bordered by the Tyrol (Austria) northeast to north ea , Dai Grigioni (Switzerland) northwest and by the Italian regions of Lombardy and Veneto to the west to the south and southeast , the Trentino-Alto Adige is one of the Italian regions with the highest density of forests (50% land ) e piÃ¹ montuosa .
In fact, the Trentino-Alto Adige occupies a large part of the Dolomites and the Alps , and is a haven for thousands of skiers and mountain lovers .
In this natural color satellite image , the vegetation is easily identifiable by the variety of green , while the mountainous terrain are shown in the formation of the various valleys and the presence of snow in midsummer .
Artistic representation shows how a satellite deceased might be struggling with a controlled re-entry into Earth's atmosphere .
Hundreds of experts from around the world will meet at the forum on the debris Europe's largest-ever this week to share research findings and discuss possible solutions <.
Satellite operators around the world are focusing their efforts on the control of space debris . Gthem scientists estimate the level of space debris orbiting the Earth in about 29 000 objects larger than 10 cm, 670 000 pieces larger than 1 cm and more than 170 million higher 1 mm – and one of these could seriously damage a spacecraft.
Clean the space above our atmosphere is a strategic goal for the ESA.
