Analysis: Europe's roadmap for space, the winners and the losers
After a day and a half of deliberations, ministers from the 17 member states of the European Space Agency (Esa), and Canada, finally signed off the budget that will shape Europe's space efforts until the end of the decade. Projects that got the go-ahead include ExoMars, the rover that will search for possible Maritan life, past or present, GMES, a key tool to understanding how the Earth's climate is changing and the use of European launchers. The main loser at the meeting was a plan to look into the feasibility of joining forces with Russia on its new crewed spaceship, the Clipper. Although the move attracted support from a number of countries, there was not enough backing to make a final decision on the matter in Berlin.  Full Story  BBC News_ 12/7/05

Images suggest Saturn moon geologically active

The international Cassini spacecraft has found visual evidence that Saturn's moon Enceladus is geologically active.

Recent images taken by the spacecraft show streams of fine, icy particles rising from the moon's south pole, suggesting they originated from warm zones in the region.  The discovery puts Enceladus in the class of geologically active moons with Jupiter's Io and Neptune's Triton.  It's unclear what causes the geologic activity, but scientists think it's due to internal heating caused by radioactivity or tides.  Full Story_CNN 12/7/05

Signs of water found deep within Mars
New observations of Mars' interior have revealed a crater hidden from the surface and new information about ice below the polar cap. The fresh research announced on Wednesday also points to the chemical signatures of past water on Mars, adding to other evidence suggesting a wet past.  Scientists have long held that the deep channels and signs of extensive aqueous erosion are evidence that Mars was once a watery world. But these geologic signatures alone are not enough to confirm that liquid water was stable on the planet’s surface for extended periods of time.  Liquid water is a key ingredient to life as we know it. While there is no firm evidence that biology has ever existed on Mars, scientists are seeking locations that may once have held standing water as logical places to search with future missions. They are also looking for hidden reservoirs of water beneath the planet's surface, which could serve as a refuge for past Martian life or a resource for future explorers.  Full StoryMSNBC_11/30/05

Possible mini solar system discovered

Astronomers have discovered what they believe is the birth of the smallest known solar system.  Peering through ground- and space-based telescopes, scientists observed a brown dwarf -- or failed star -- less than one hundredth the mass of the sun surrounded by what appears to be a disk of dust and gas. The brown dwarf -- located 500 light years away in the constellation Chamaeleon -- appears to be undergoing a planet-forming process that could one day yield a solar system, said Kevin Luhman of Pennsylvania State University, who led the discovery. Full Story_CNN 11/30/05

Japanese space probe lands on asteroid: Kyodo
A Japanese probe on a mission to bring back the first rock samples from an asteroid landed briefly on its target on Sunday but did not drop the equipment for collecting surface material, Kyodo news reported on Wednesday.  Scientists from the Japan Aerospace Exploration Agency (JAXA) had said earlier the unmanned probe failed to touch down on Itokawa, nearly 300 million km (186 million miles) from earth. After a voyage of 2-½ years, the space probe stayed on the surface of the 548-metre-long asteroid for 30 minutes, marking the first landing by a Japanese spacecraft on a celestial body, Kyodo said.  Full Story_Reuters 11/23/05

Company makes bid for space travel

Astronauts and passengers can go to space by 2008 if the company making the spaceship gets the funding, company officials said.  Jim Benson, chief executive officer of SpaceDev, said all it needs is $20 million in funding to develop the Dream Chaser, a NASA concept designed in the 1980s but never built, New Scientist reports.  The funding would pay for suborbital flights and an additional $100 million would enable Dream Chaser to take six people to the International Space Station by 2010.  The Dream Chaser is billed as a safer alternative than today's space ships.  It doesn't carry heavy cargo and uses a different fuel than the cryogenic fuel used in Columbia and Discovery.  Dream Chaser will use a mixture of nitrous oxide and rubber as fuel. Full Story_ UPI 11/17/05

Link 'lost' with asteroid robot
Japan's space agency has lost contact with a robotic probe that it dispatched to explore the surface of an asteroid, according to reports.  The small probe called Minerva was released from its mothership Hayabusa on Saturday, but officials say its "current status is still unknown".  Hayabusa is hovering near asteroid Itokawa, in preparation to collect surface samples for return to Earth.  Full Story_BBC 11/16/05

"Gravity Tractors" could outwit killer asteroids

No need to send Bruce Willis into space with a nuclear bomb -- the best way to deal with a killer asteroid hurtling toward Earth could be a "gravity tractor."  Two NASA astronauts, gently mocking the solution offered in the Hollywood blockbuster "Armageddon," have come up with a deceptively simple plan to pull asteroids off course.  Edward Lu and Stanley Love have proposed that a rocket be launched into space, effectively to act as a giant magnet.  Landing on an asteroid, which is no more than a spinning pile of rubble, is very difficult to achieve.  Instead, the gravity tractor would travel alongside the asteroid and gradually pull it off course, using nothing more than the gravitational pull between the two bodies.  "This saves you from having to land on the asteroid and then trying to stabilize yourself on a flying pile of rock and debris which is spinning all the time," Love told Reuters after their plan was published on Wednesday in the science journal Nature.  Full Story_Reuters 11/9/05

All go for giant comms satellite
Inmarsat-4 F2, one of the largest and most powerful communications satellites ever built, has succesfully launched from a floating pad in the Pacific. The six-tonne UK-built craft was carried aloft by a Zenit-3SL rocket at approximately 1407 GMT on Tuesday. The launch had twice been postponed after a software glitch stopped the countdown sequence on Saturday. Inmarsat-4 F2 is designed to improve broadband and 3G communications, principally in the Americas. It is the second in a planned two-satellite constellation. The first spacecraft launched in March covers most of Europe, Africa, the Middle East, Asia and the Indian Ocean. The new satellite will improve and extend communications across South America, most of North America, the Atlantic Ocean and part of the Pacific Ocean. The two satellites will support the London-based Inmarsat company's global broadband network, BGan. Full Story_BBC 11/8/05

Planet Venus: Earth's 'evil twin'

The Babylonians called it "Ishtar". To the Mayans, it was known as "Chak ek", which translates as "great star". Venus is the brightest object in the sky except for the Sun and Moon. As such, the second planet from the Sun has fascinated humankind for millennia. Europe's Venus Express spacecraft blasts off this week, and will rendezvous with our nearest planetary neighbour next year to study it from orbit. The mission aims to shed light on an enduring mystery about this world: how a planet so similar to our own in size, mass, and composition has evolved so differently over the last 4.6 billion years.  Full Story BBC News_ 11/7/05

Last Titan rocket blasts off; an era ends

For the 368th and last time, the United States launched a Titan rocket into space October 19. The blastoff of the 16-story, unmanned Titan IV signaled the end of an era that began in 1959, as the US military converts to cheaper space boosters. The last Titan carried a secret payload for the National Reconnaissance Office, which oversees the nation’s spy satellites. Titan’s past included many high-profile missions, including boosting Gemini manned spacecraft into orbit in the mid-1960s as preparation for the Apollo moon landings. The workhorse rocket, originally designed as a weapon-bearing intercontinental ballistic missile for the Cold War, also sent many scientific craft on their way to Mercury, Mars and the outer planets.  Full Story  AP/Daily Times_ 10/24/05

Saturn moon is a frigid world; Dione an 'older, more mature moon,' says Cassini scientist

A close flyby of Saturn's grayish moon Dione reveals it is a mature, frigid world with hints of tectonic activity, new observations suggest. The U.S.-European Cassini spacecraft flew within 310 miles (500 kilometers) of the Dione's pale surface last week, showing it possessed a heavily cratered surface but no presence of an atmosphere. Cassini scientists compared the frozen Dione to another Saturn moon, Enceladus, which recently was found to have active ice volcanoes and a significant atmosphere.  Full Story_CNN 10/19/05

Saturn's rings surprise scientists

Rings have changed over the past 25 years

New observations by the international Cassini spacecraft reveal that Saturn's trademark shimmering rings, which have dazzled astronomers since Galileo's time, have dramatically changed over just the past 25 years. Among the most surprising findings is that parts of Saturn's innermost ring -- the D ring -- have grown dimmer since the Voyager spacecraft flew by the planet in 1981, and a piece of the D ring has moved 125 miles inward toward Saturn. While scientists puzzle over what caused the changes, their observations could reveal something about the age and lifetime of the rings.  Full Story_CNN 9/6/05

Deep Impact probe shows a fragile, empty comet
Comet Tempel 1, the target of NASA's Deep Impact probe, turns out to be quite fragile, with no more substance than a snowbank, scientists said on Tuesday. "The comet is mostly empty, mostly porous," said Michael A'Hearn, a comet specialist at the University of Maryland. "Probably all the way in, there is no bulk ice. The ice is all in the form of tiny grains." The material on the comet's surface, down to a depth of several dozen yards (meters) is "unbelievably fragile, less strong than a snowbank," A'Hearn said in a telephone news briefing to release early findings from the mission.The comet's dust and ice grains form a fluffy structure of fine particles held together loosely by a weak gravitational pull, the researchers said.  Full Story_ Reuters 9/6/05

Giant water plume spews from Saturn’s moon

Four fissures in the south pole of Saturn's moon Enceladus are spewing out a plume hundreds of kilometres high, the Cassini probe has revealed, and the ejecta is leaving a vapour trail that rings Saturn.  Scientists are shocked by this volcanic activity on what should be a small, quiet moon. "It is a stunning surprise," said Dennis Matson, from NASA's Jet Propulsion Laboratory in Pasadena, California, US.

Shuttle delay may threaten space station

Scientists believe the future of the International Space Station could be threatened by the Nasa's decision to ground its shuttles. The US space agency has said March 4 is the next target date for a shuttle launch as they investigate safety concerns surrounding foam falling away from Discovery during its recent launch. The shuttle is the only vehicle that can transport parts to complete the building of the space station, a 16-nation project to create a laboratory to study the effects of space on human beings. Following the Columbia shuttle accident in 2003, which killed seven astronauts, maintenance trips to the space station have been carried out by Russian rockets.  Andrew Coates from UCL's Mullard Space Science Laboratory said: "The knock-on effects to the International Space Station are quite dramatic. Long delays could potentially be a show-stopper for the whole thing."  Full Story_ITN 8/19/05

Voyager 1 reaches solar system's final frontier
NASA's Voyager 1 has reached the final frontier of our solar system.  Astronomers tracking the little spaceship's 26-year journey from Earth believe Voyager 1 has gone through a region known as termination shock, some 8.7 billion miles from the Sun, and entered an area called the heliosheath.  Voyager 1 and its twin spacecraft Voyager 2 were launched in 1977 on a mission to explore the giant planets Jupiter and Saturn. The pair kept going, however, and the mission was extended.  Voyager 2 went on to explore Uranus and Neptune, the only spacecraft to have visited these outer planets. Both Voyagers are now part of the Voyager Interstellar Mission to explore the outermost edge of the Sun's domain.  Both Voyagers are capable of returning scientific data from a full range of instruments, with adequate electrical power and attitude control propellant to keep operating until 2020.  Wherever they go, the Voyagers each carry a golden phonograph record which bears messages from Earth, including natural sounds of surf, wind, thunder and animals. There are also musical selections, spoken greetings in 55 languages, along with instructions and equipment on how to play the record.  Full Story_ Reuters 5/25/05

Boosted by a return to success for its satellite launch program and needled by China's achievements, Japan's space agency (JAXA) wants to put a manned space station on the moon, though it may struggle to raise funds.  JAXA says it would need a hefty increase in budget and personnel to carry out its proposals, which may be hard to secure given Japan's 751 trillion yen ($6,937 billion) national debt.

Huygens success: Space probe lands on Saturn's largest moon, Titan and sends back first set of data

The spacecraft probe was transmitting data for over two hours after it landed, space scientists confirmed. They're piecing together the images, measurements and sounds and hope they might even hear lightning strikes when they analyse the data. The European-built probe should have taken about 750 images during its two-and-a-half-hour descent, shedding light on a cosmic enigma. Dominated by nitrogen, methane and other organic (carbon-based) molecules, conditions on Titan are believed to resemble those on Earth 4.6 billion years ago. As such, it may tell scientists more about the kind of chemical reactions that set the scene for the emergence of life on Earth.  Full Story  BBC News_ 1/14/05
