Cassini Captures Best View Yet Of Saturn's Ring Currents![]() Scientists have gotten their best "look" ever at the invisible ring of energetic ions trapped in Saturn's giant magnetic field, finding that it is asymmetric and dynamic, unlike similar rings that appear around Earth. Using the Magnetospheric Imaging Instrument on NASA's Cassini spacecraft, a team led by Dr. S. Krimigis of the Johns Hopkins University Applied Physics Laboratory (APL) disco ... more Constellation Services International And Space Systems Loral Team On NASA COTS Proposal ![]() Constellation Services International is collaborating with Space Systems Loral (SS/L) to pursue a funded Space Act Agreement with NASA's Commercial Orbital Transportation Services (COTS) program. The two companies are working together, with SS/L as the prime, to produce a commercial cargo system to re-supply NASA's International Space Station (ISS), and to create new commercial space services a ... more Planetary Scientists Close In On Saturn' Elusive Rotation ![]() Somewhere deep below Saturn's cloud tops, the planet rotates at a constant speed. Determining this interior period of rotation has proven extremely complicated. Now, with new Cassini results, a team of European scientists have taken an important step forward. The results, published in Nature, are based on data from the Radio and Plasma Wave Science instrument on Cassini. Determining the l ... more NASA Sends Spacecraft On Mission To Comet Hartley 2 ![]() NASA has approved the retargeting of the Epoxi mission for a flyby of comet Hartley 2 on Oct. 11, 2010. Hartley 2 was chosen as Epoxi's destination after the initial target, comet Boethin, could not be found. Scientists theorize comet Boethin may have broken up into pieces too small for detection. The Epoxi mission melds two compelling science investigations -- the Extrasolar Planet Obse ... more Russia Soon To View Two Space Transport Projects ![]() Russia's rocket and space corporation Energia has developed six projects for new manned spacecraft, two of which will be submitted to Russia's space agency in the near future, a source said Wednesday. "Two of the most attractive projects for spacecraft as part of a reusable manned transport system could be submitted to the Federal Space Agency in the near future," the spokesman said.

![]() ![]() Chinese scientists have pledged to seize time to start the plan and implementation for the second-phase of China's lunar probe program at a red-carpet ceremony opened on Wednesday morning to mark the country's initial success in deep space exploration. Zhang Qingwei, Minister in charge of the Commission of Science, Technology and Industry for National Defence, said the immediate tasks faci ... more NASA Targets Space Shuttle Atlantis Launch For January 10 ![]() NASA's Space Shuttle Program managers have targeted Jan. 10 for the launch of shuttle Atlantis' STS-122 mission to the International Space Station. "The workforce has stepped up to and met every challenge this year," said Wayne Hale, Space Shuttle Program manager at NASA's Johnson Space Center. "Moving the next launch attempt of Atlantis to Jan. 10 will allow as many people as possible to ... more LOFAR Picks Up Speed ![]() Bonn, Germany (SPX) Dec 14, 2007 The Max Planck Institute for Radio Astronomy has teamed up with The Netherlands Institute for Radio Astronomy, ASTRON, to realise the first international telescope station of the LOFAR radio telescope. LOFAR is the LOw Frequency ARray, initiated by ASTRON with stations centred on Exloo in the northeast of The Netherlands, and is now becoming an international pro ... more Lightning Protection For The Next Generation Spacecraft ![]() Thunder rumbles in the distance as darkening clouds gather above NASA Kennedy Space Center's Launch Pad 39B, where a sleek Ares I launch vehicle stands awaiting an upcoming flight. A blinding lightning flash suddenly streaks down from the sky, striking one of the pad's tall steel masts. The surge of electrical current quickly is diverted away from the rocket and carried safely into the ground. ... more India successfully tests surface-to-air Akash missile ![]() India carried out a successful test on Thursday of its surface-to-air Akash missile at an eastern coastal testing range, defence officials said. The missile blasted off from the Chandipur-on-Sea testing site, 200 kilometres (125 miles) northeast of Orissa state capital Bhubaneswar and hit a flying target successfully, a defence ministry official. The locally developed missile was lasted ... more |

![]() ![]() The University of East Anglia and the Met Office's Hadley Centre have released preliminary global temperature figures for 2007, which show the top 11 warmest years all occurring in the last 13 years. The provisional global figure for 2007 using data from January to November, currently places the year as the seventh warmest on records dating back to 1850. The announcement comes as the Secre ... more UN Climate Conference Hears How EO Can Help ![]() The role of Earth Observation satellites in combating climate change is being highlighted at the United Nations climate change conference where thousands of delegates from more than 180 countries are gathered to begin negotiations of an international emissions-cutting agreement to succeed the Kyoto Protocol, whose first commitment period ends in 2012. The Protocol commits its signatories t ... more Large Earthquakes May Broadcast Warnings But Is Anyone Tuning In To Listen ![]() Like geological ninjas, earthquakes can strike without warning. But there may be a way to detect the footfalls of large earthquakes before they strike, alerting their potential victims a week or more in advance. A Stanford professor thinks a method to provide just such warnings may have been buried in the scientific literature for over 40 years. In October, Japan instituted a nationwide ea ... more Tropical Storm Olga's death toll in Caribbean reaches 25 ![]() The toll from Tropical Storm Olga's Caribbean rampage Thursday rose to 25 confirmed deaths, most in the Dominican Republic. The worst hit was Santiago, the second largest city in the Dominican Republic, where 17 deaths were reported after rising waters forced authorities to release water from a dam into the already swollen Yaque river. Most of the victims drowned in the floodwaters, auth ... more Earth's Heat Adds To Climate Change To Melt Greenland Ice ![]() Scientists have discovered what they think may be another reason why Greenland 's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered. The researchers don't yet know how warm the hotspot is. But if it is warm en ... more
