During the Show Air Berlin 2010, Airbus announced commitments for its wide range of products for a total of 67 aircraft, from the value of more than 15,3 billions of dollars. The purchase commitments include a firm order for 32 A380 aircraft valued at approximately 11,5 billions of dollars, added to which arrangements (MoU) for further 35 aircraft worth about 3,8 billions of dollars.
The event highlight of the show was the order by Emirates Airline for 32 A380 aircraft, through which the airline based in Dubai brings to the height 90 specimens the total number of firm orders for this aircraft model. Emirates has supported the development of the A380 from the earliest moments, and this order - the largest single order ever made for the A380 - is an unequivocal confirmation of the exceptional performance both on-board service and the ability to allow the aircraft to airlines that use this model in a growth industry.
In addition to this firm order, purchase commitments reached during the show include a Letter of Intent for 35 aircraft from the total value of about 3,8 billions of dollars, of:
· TAM Airlines, 5 A350-900 aircraft valued at approximately 1,3 billions of dollars, more 20 A320 Family aircraft of the total value of about 1,7 billions of dollars ( six A319, seven A320s and seven A321s);
· Finnair, five A321s worth a total of 485 million dollars. These aircraft will be equipped with optional new device "Sharklet" for better performance;
· Germany, five A319s worth a total of 372 million dollars.
Maybe the Mayans were right. In less than 150 years, the solar system will enter the so-called ”Local Bubble".
In this area, hundreds of light years wide, the number of cosmic radiation is significantly more intense than what happens now.
The prediction of ' Astrophisical Journal Letters says "Perhaps future generations will have to learn to defend space technologies by stronger flow of radiation", the authors. "A unsettling prospect", has called the Director of Arcetri Observatory of the National Institute of Astrophysics (Inaf), Francis Ball.
"We already knew that the Sun, the planetary system, is immersed in a cloud of passage, produced in the explosion ofsupernovae, call Local Interstellar Cloud, great tens of light years and consists essentially of hydrogen at low density, about one atom per cubic centimeter, and where temperatures reach a few thousand degrees. This cloud is located within the transitional Local Bubble, where the density of particles is even lower and the temperatures are a thousand times higher" adds the director of the INAF, specifying that the solar system is about to exit the Cloud Locale to plunge into Bubble.
And then what will happen? You can not make predictions, but certainly one of only a century or two and the Earth will enter into the oven.

The first GOCE satellite data, are now available online. ESA launched the satellite in March 2009 to map Earth's gravity with unprecedented accuracy.
The final gravity map of the geoid model and provide users with data to advance fundamental science and applications in a wide range of disciplines.
However, There are a number of steps that must be taken to transform raw data into products suitable for users.
The raw data are downloaded from the GOCE ground stations Kiruna, in northern Sweden, and Svalbard, in Norway. They are immediately transmitted to ESA's European Space Operations Centre (ESOC) a Darmstadt, in Germania, e all’European Space Research Institute (ESRIN), Frascati, Italy. That, through a process of calibration and validation, i dati subiscono una trasformazione importante di telemetria a ‘prodotti dati a livello di-1b’.
The Level-1b products are the series of measurements converted, calibrated and validated. They consist mainly of gravity gradients in the reference frame of the instrument and orbital data in a coordinated Earth-fixed system.
"GOCE is proving to be an extraordinary mission, and we are more than confident that these data not only will change the way we view the gravitational field of our planet, but also the manner in which the information is used in many branches of geosciences . "
