The Little Red Spot Of Jupiter Has Lots Of Winds Blowing![]() Using data from NASA's New Horizons spacecraft and two telescopes at Earth, an international team of scientists has found that one of the solar system's largest and newest storms - Jupiter's Little Red Spot - has some of the highest wind speeds ever detected on any planet. The New Horizons researchers combined observations from their Pluto-bound spacecraft, which flew past Jupiter in Febru ... more Arianespace Completes The Assembly Of Another Ariane 5 ![]() Arianespace's third Ariane 5 of 2008 is now complete following the integration of its Turksat 3A and Skynet 5C telecommunications satellites at the Spaceport in French Guiana. This activity took place in the upper level of the Spaceport's Final Assembly Building, where Turksat 3A was installed atop the launcher's core cryogenic stage, followed by the integration of Skynet 5C. The upc ... more Foot-Dragging Mars Rover Finds Yellowstone-Like Hot Spring Deposits ![]() Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. Such deposits are found around hydrothermal vents like those in Yellowstone National Park. That's the conclusion of planetary scientists working with data collected by the rover's Miniature Thermal Emission Spe ... more Heat-Sensing Camera Helps Phoenix Probe Land Safely On Mars ![]() On Sunday, May 25, 2008, the Phoenix spacecraft (a joint project between NASA and the University of Arizona) will arrive at Mars after a 10-month cruise from Earth. Traveling initially at 12,500 miles per hour (5.7 kilometers per second), Phoenix will make a hair-raising, nail-biting, 6-and-a-half-minute plunge though the Martian atmosphere to a smooth landing on icy dirt not far from the edge ... more Mars Express Support To Phoenix Landing ![]() Beginning late on 25 May, Mars Express will execute a series of pre-programmed commands specially designed to support NASA's Phoenix lander. The ESA spacecraft will conduct a high-speed slew, enabling it to track Phoenix as it enters the martian atmosphere. Mars Express will point its Lander Communications Antenna toward Phoenix's planned entry trajectory and record signals transmitted fro ... more |

![]() ![]() Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time. While looking at another object in the spiral galaxy NGC 2770, using NASA's orbiting Swift telescope, Carnegie-Princeton fellows Alicia Soderberg and Edo Berger detected an extremely luminous blast of X-rays released by a supernova explos ... more Stellar Death Caught In The Act ![]() Thanks to a fortuitous observation with NASA's Swift satellite, astronomers for the first time have caught a star in the act of exploding. Astronomers have previously observed thousands of stellar explosions, known as supernovae, but they have always seen them after the fireworks were well underway. "For years we have dreamed of seeing a star just as it was exploding, but actually finding ... more Observation Of X-Rays From Birth Of Supernova Leads To All-Out Effort To Record Stellar Death ![]() The lucky capture in January of an X-ray outburst from the very beginning of a supernova allowed astronomers around the world to quickly follow up with ground-based telescopes and collect a wealth of new information on early processes in stellar explosions, according to a paper newly submitted to The Astrophysical Journal. On Jan. 9, 2008, NASA's Swift satellite captured the X-ray burst ... more New Red Spot Appears On Jupiter ![]() In what's beginning to look like a case of planetary measles, a third red spot has appeared alongside its cousins-the Great Red Spot and Red Spot Jr.-in the turbulent Jovian atmosphere. This third red spot, which is a fraction of the size of the two other features, lies to the west of the Great Red Spot in the same latitude band of clouds. The new red spot was previously a white oval ... more NASA's Swift Satellite Catches First Normal Supernova In The Act Of Exploding ![]() Thanks to a fortunate observation with NASA's Swift satellite, astronomers, for the first time, have caught a normal supernova at the moment of its birth--the first instant when an exploding star begins spewing its energy into space, transforming into a supernova that during its brief lifetime will shine brighter than billions of stars combined. Until this discovery, the only supernovae gl ... more |

"I don't think the situation is completely hopeless but those decisions that have been taken cannot please us and we will be forced to find an adequate response," Medvedev said in an interview with Chinese ... more Outside View: S-400 missile system delays ![]() The Russian Topol strategic missile launchers that rolled through Red Square on May 9 were impressive to the eye, though I hope there is no intention to use these weapons. Meanwhile the "density" of armed conflicts across the world keeps growing, and the main role in these conflicts is played by conventional yet precision weapons. The missile defense system being set up by the ... more White House sees Russia 'open' to talks on US missile plan ![]() The White House said Thursday it recognizes Moscow's concerns over a US missile defense system in Europe but sees new Russian President Dmitry Medvedev as "open" to discussions about the plans. "The United States and Russia are going to continue to work together on this issue," National Security Council spokeswoman Kate Starr told AFP. "We understand they have concerns, but we are please ... more LaBarge Awarded Contract For Upgraded Missile Launch System ![]() LaBarge has secured a multiyear agreement with Raytheon Missile Systems to provide complex cable assemblies for the upgraded Rolling Airframe Missile (RAM) Guided Missile Weapon System. For fiscal 2008, initial releases under the agreement total approximately $1.4 million. The total anticipated value of the agreement for LaBarge through 2011 is $4.5 million. Production on the ... more
