The Moscow State University ( MSU) will celebrate next year , the anniversary of the great Russian scientist whose name it bears – Mikhail Lomonosov . To mark the tercentenary of the birth of its founder , the MSU will launch a satellite and will provide Lomonosov ‘s most powerful supercomputer in the world. It is the rector of MSU Viktor Sadovnitchi , which revealed these plans in late May in Arkhangelsk ( north) , at a meeting of the organizing committee for preparing the celebration.
The satellite will Lomonosov for the study , including natural phenomena and atmospheric. ” The satellite is being manufactured , said Viktor Sadovnitchi . It will be a heavy satellite , which weighs 500 kilograms. are being reserved for a rocket launch, but the funding program of the University that works ducts are not yet ratified . ”

In equatorial areas , where vegetation is dense and sometimes mountainous terrain , the extent of displacement of a few centimeters of a satellite in flight at 7 km per second at 700 km altitude can be difficult.
The Centre for Remote Imaging , Sensing and Processing ( CRISP ) of the National University of Singapore ( NUS ) aims to develop advanced technologies in the field of remote sensing to meet scientific , technical and trade of Singapore and ASEAN region . CRISP operates a satellite ground station for data acquisition by remote sensing satellite and for treating them, integrating them into standard products , high value -added research and commercialization.
The research center is moved to a higher level of research with radar interferometric synthetic aperture (InSAR ) . It is the only group in the region after Japan , which has managed to produce interferometric maps on the equatorial regions. The interest in the use of InSAR compared with the Global Positioning System ( GPS ) , is the ability to obtain more information with greater accuracy and also on soil and detect movements not detectable with GPS.

Dramatic predictions of which are caused by global warming could stop the deep ocean currents with dramatic effects on climate, it will probably not fill. Contends that scientists from the American Geophysical Union (AGU), who at seven years of continuous research, the Gulf Stream did not detect any signs of slowing down.
Gulf Stream and follow the currents have a major impact on the circulation of heat around the planet. According to previous studies, the melting of ice associated with the inflow of cold water into the North Atlantic could stop these currents, which would in turn caused a dramatic cooling and the onset of a new Ice Age. In 2004, this theory became a model of catastrophic slide next day.
Scientists studied ocean currents from 2002 to 2009 for assistance in-depth and surface probes, whose movement was monitored by satellite. The study confirmed that in the short term, subject to the flow of dramatic changes in the oceans, is not it but to detect any long-term trend.

The Japanese space agency (JAXA) announced March 15 a successful experience of astronomical data transfer using its satellite broadband Internet WINDS. The project is a cooperation between JAXA and the Astronomical Observatory Japan (NAOJ) under the VERA program.
VERA (VLBI Exploration of Radio Astrometry) is a network of four telescopes used for Japanese Interferometry Very Long Baseline Interferometry (VLBI). The radio astronomy antennas are located in different regions of Japan (Iwate prefectures of Tokyo, Kagoshima and Okinawa). The data gathered since 2003 they aim to achieve a model of the Milky Way. The distance of each star from Earth is calculated by measuring the annual parallax, that is to say, observing the same object at six month intervals. In this process of astronomical interferometry, data received simultaneously by each antenna are marked with a specific time and are then sent to the Mitaka campus where they are compiled and analyzed.

The future satellite FORMOSAT-5 [1], whose commissioning is expected in 2013, should carry a remote sensing instrument [2] fully developed locally [3] [4]. This advance will overcome the difficulties encountered by Taiwan in the acquisition of components subject to export controls with traditional CCD sensors photographic device (charge transfer) [5], replaced by a CMOS (semi – Driver complementary metal-oxide) [6] local.

In a satellite galaxy of the Milky Way, astronomers have spotted a star similar to the old stars in the galactic halo. The discovery supports the theory that our galaxy grew by absorbing small satellite.
According to the model of galaxy formation hierarchical said, the current large galaxies grew by swallowing smaller neighbors. The Milky Way would be formed in part of small satellite galaxies absorbed during its history. But the apparent absence in the current satellite galaxies, stars chemically similar to the oldest of the Milky Way had cast doubt on this scenario. Spectroscopic analysis of an old star in the Sculptor dwarf galaxy by the team of Anna Frebel, the Harvard-Smithsonian Center for Astrophysics, raises the question today: its chemical composition is similar to that of stars the galactic halo, in agreement with the scenario based on the hierarchical model.

NASA last night sent to orbit the Earth the latest U.S. weather satellite GOES-P. This will be a six-month test period the next ten years to send data to Earth about atmospheric conditions on the planet.
Satellite GOES-P, which will be entering the orbit renamed GOES-15 is the last type of the GOES series of satellites. The first of these was used in 1975.
Satellite will focus on monitoring the rapid changes in the atmosphere, which can result in severe storms and flooding. Part of the satellite sensor that sends data to scientists, which can calculate the temperature, humidity and ozone distribution.
Satellites will also provide information about possible pollution orbit, which could interfere with navigation and communications in space. Satellite is also able to monitor the solar energy that is released into space by electromagnetic radiation.

GOCE (Ocean Circulation Explorer and gravity) of the European Space Agency (ESA) will be released this spring, as the agency recently announced. This satellite is designed to provide unique models of the gravitational field of the earth’s surface, especially the oceans, on a global scale with an accuracy and unprecedented spatial resolution.
GOCE will significantly improve our understanding of the physics of the Earth and climate research, according to its creators. Thanks to information provided by the instruments on the
spacecraft, scientists hope to learn new information about
Earth’s gravitational field, ocean circulation and sea level variations, thus enabling better understand the functioning of the planet.
On April 3 will take place the official presentation of the mission at the European
Space Research and Technology Center (ESTEC) of ESA in Noordwijk (Netherlands).
Managers, aerospace, scientific and other experts involved in the project set out its objectives. It will also show the satellite before being transported to Russia for launch. The launch will take place aboard a Rockot launcher from Plesetsk (Russian Federation).

A mechanism of resonance with a now defunct satellite would explain why the rotation axis of Uranus is almost perpendicular to that of other planets.
Uranus has a special place in the solar system: its axis of rotation is tilted 97 degrees to the axis of its orbit around the sun instead of being so close as to other planets. In other words, Uranus is lying completely on its orbit. According Gwenael Boue and Jacques Laskar, of the Institute of Celestial Mechanics and Ephemeris Calculation (IMCCE) in Paris, this obliquity result of a resonance induced by a satellite which, during the formation of the solar system would have tipped gradually the axis of rotation of the planet.
The mechanism previously invoked to explain this inclination was collision with a protoplanet the size of the Earth at the time of planet formation. But such a collision would have tipped the axis of rotation of the planet, without the satellites that follow.
