From Cosmos:

SYDNEY: New images of the far side of the Moon show that volcanoes continued to erupt there for much longer than previously thought.

The Moon is covered by large 'seas' of basalt, called mares. Most mares stopped forming three billion years ago, one billion years after the Moon formed from a collision between the Earth and another nascent planetoid.

Episodic volcanism

However, several mare deposits on the lunar farside (the side that always faces away from Earth) show a much younger age of around 2.5 billion years old, according to research published today in the U.S. journal Science.

These young ages indicate that mare volcanism on the Moon lasted longer than experts realised and may have occurred episodically, the authors write.

New Scientist Space:

The arrival of spring in southern Mars is reviving NASA's two venerable Mars rovers as deepening autumn in the arctic north slowly freezes the Phoenix lander.

After hibernating for the winter on the northern edge of a plateau called Home Plate, the Spirit rover moved uphill in October to collect more sunlight.

On the other side of the planet, the Opportunity rover, which climbed out of a large crater called Victoria at the end of August, has completed the first month of a 12-kilometre trek towards an even bigger crater called Endeavour. That journey is expected to take more than two years.

Designed to last only 90 days, the two rovers have survived for nearly five years on the Red Planet. Both are showing their age, but Jake Matijevic, chief of rover engineering at NASA's Jet Propulsion Laboratory in Pasadena, California, says they still are doing fine.

Web's Eulogy For The Phoenix Mars Lander

From PopSci:

As NASA's robotic 'naut tweets away its dying breath, the blogosphere pays its respect

NASA has begun bidding a planned goodbye to its Phoenix Mars Lander. The lander relies on solar panels and the sun's golden touch to reawaken it each day, but a dust storm has hastened the end in the face of the oncoming Martian winter.

However, the lander's cold fate has evoked an outpouring of netizen love. Wired hosted a pithy epitaph contest to mark the occasion. Phoenix also polished its geek credentials by guest-blogging for Gizmodo about its mission. Readers can still catch Phoenix's personal Twitter stream from the popular social networking site, complete with robotic tweets such "Space exploration FTW!"

The Historic Beginnings Of The Space Arms Race Part Two

From Space War:

he Soviet government was set to adopt the Polyot-Kosmos anti-satellite -- ASAT -- weapons system after Kosmos-252 successfully destroyed the first spacecraft in orbit on Nov. 1, 1968, and after successful subsequent launches.

However, in 1972 the Soviet Union and the United States signed the Strategic Arms Limitation Treaty -- SALT-I -- and the Anti-Ballistic Missile -- ABM -- Treaty, which also covered ASAT systems.

Depending on the pace of bilateral talks, the ASAT test program was either mothballed or resumed. The ASAT system was eventually adopted and subsequently upgraded.

In 1976 the Soviet Union began to launch second-generation satellite interceptors, featuring new target-acquisition and homing systems, first installed aboard Kosmos-814. Flying along a lower orbit, the latter quickly overtook the target satellite, accelerated and found itself less than 1,000 meters from the "victim."

India's Lunar Probe Sends Its First Pictures From Space

From World News/RIA Novosti:

NEW DELHI, November 1 (RIA Novosti) - NEW DELHI, November 1 (RIA Novosti) - India has received the first space photographs from its unmanned spacecraft on a mission to the Moon, the Indian Space Research Organization said on Saturday.

Chandrayaan-1 was launched into space by the Indian-built PSLV-C11 rocket on October 22, and is set to enter the Moon's orbit on November 8. Chandrayaan means "Moon Craft" in ancient Sanskrit.

On-board cameras took pictures of the Earth from distances of 9,000 km (5,594 miles) and 70,000 km (43,505 miles).

India's first lunar mission signifies the country's breakthrough into the club of space powers, making it the third Asian country after Japan and China to carry out a lunar flight.

Neil Armstrong Donating His Papers To Purdue

From AP:

WEST LAFAYETTE, Ind. – Former astronaut Neil Armstrong has agreed to donate personal papers dating from the start of his flight career to his alma mater, Purdue University.

Armstrong's papers, boxes of which have already begun arriving at Purdue, will be an inspiration for students and invaluable for researchers, said Sammie Morris, assistant professor of library science and head of Purdue Libraries' Archives and Special Collections.

"For researchers, it's going to be a boon. No one has been able to research these papers or study them," Morris said.

Purdue President France A. Cordova, who became NASA's first female chief scientist, plans to announce Armstrong's donation Saturday before the Purdue-Michigan football game.

From Space Daily:

ScienceDaily (Oct. 31, 2008) — A NASA spacecraft gliding over the battered surface of Mercury for the second time this year has revealed more previously unseen real estate on the innermost planet. The probe also has produced several science firsts and is returning hundreds of new photos and measurements of the planet's surface, atmosphere and magnetic field.

The Mercury Surface, Space Environment, GEochemistry, and Ranging, or MESSENGER, spacecraft flew by Mercury shortly after 4:40 a.m. EDT, on Oct. 6. It completed a critical gravity assist to keep it on course to orbit Mercury in 2011 and unveiled 30 percent of Mercury's surface never before seen by a spacecraft.

Buzz Aldrin: Mars Pioneers Should Stay There

Buzz Aldrin

From Cosmos:

PARIS: The first astronauts sent to Mars should be prepared to spend the rest of their lives there, in the same way that European pioneers headed to America knowing they wouldn't return home, says moonwalker Buzz Aldrin.

In an interview with reporters, the second man to set foot on the Moon said the Red Planet offered far greater potential than Earth's satellite as a place for habitation.

No coming back

With what appears to be vast reserves of frozen water, Mars "is nearer terrestrial conditions, much better than the Moon and any other place," Aldrin, 78, said in a visit to Paris last week. "It is easier to subsist, to provide the support needed for people there than on the Moon."

It took Aldrin, Neil Armstrong and Michael Collins eight days to go to the Moon – 380,000 km from Earth – and return in July 1969, aboard Apollo 11.

Going to Mars, though, is a different prospect. The distance between the Red Planet and Earth varies between 55 million km and more than 400 million km. Even at the most favourable planetary conjunction, this means a round trip to Mars would take around a year and a half.

"That's why you [should] send people there permanently," said Aldrin. "If we are not willing to do that, then I don't think we should just go once and have the expense of doing that and then stop."

Phoenix Enters Safe Mode

(Image from NASA)

From Mars Daily:

NASA'S Phoenix Mars Lander entered safe mode late yesterday in response to a low-power fault brought on by deteriorating weather conditions. While engineers anticipated that a fault could occur due to the diminishing power supply, the lander also unexpectedly switched to the "B" side of its redundant electronics and shut down one of its two batteries.

During safe mode, the lander stops non-critical activities and awaits further instructions from the mission team. Within hours of receiving information of the safing event, mission engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., and at Lockheed Martin in Denver, were able to send commands to restart battery charging. It is not likely that any energy was lost.

New NASA Capsule Orion Resembles Apollo
-- L.A. Times

The agency unveils the test module for structural testing at Edwards Air Force Base. The capsule, designed to carry humans to the moon, looks a lot like the one that first did so four decades ago.

Reporting from Edwards Air Force Base -- NASA rolled out its next-generation space capsule here Wednesday, revealing a bulbous module that is scheduled to carry humans back to the moon in 2020 and eventually onward to Mars.

Unlike the space-plane shape of the shuttles, the new Orion Crew Exploration Vehicle looks strikingly similar to the old Apollo space capsule that carried Neil Armstrong, Buzz Aldrin and Michael Collins to the moon and back in 1969, with Armstrong and Aldrin becoming the first humans to walk on the lunar surface.

There is one key difference, however. The test module, unveiled at NASA's Dryden Flight Research Center, is substantially bigger -- 16.5 feet in diameter compared with Apollo 11's 12.8 feet.

The craft's extra girth will allow it to carry six astronauts instead of Apollo's three.

"This is the same shape as Apollo," said Gary Martin, the project manager for the test program at Dryden. "But the extra space translates into twice as much volume as Apollo."

Still, cramming six astronauts inside will make it "pretty cozy," he said.

New Minerals Point To Wetter Mars

(Photo from NASA Astrobiology Institute)

From The BBC:

A Nasa space probe has discovered a new category of minerals spread across large regions of Mars.

The find suggests liquid water remained on Mars' surface a billion years later than scientists had previously thought.

The US Mars Reconnaissance Orbiter (MRO) spacecraft found evidence of hydrated silica, better known as opal.

The discovery adds to the growing body of evidence that water played a crucial role in shaping the Martian landscape and - possibly - in sustaining life.

Hydrated, or water-containing, minerals are telltale signs of when and where water was present on ancient Mars.

Researchers made the discovery using the Compact Reconnaissance Imaging Spectrometer (CRISM) instrument on MRO.

Space Tourist Enthusiastic About His Voyage

'Flawless' landing: Ground crew help U.S. space tourist Richard Garriott after the Soyuz capsule touches down (Photo from The Daily Mail)

'What A Ride!' Space Tourist And Russian Cosmonauts Return To Earth In 'Flawless' Landing -- Daily Mail

British-born space tourist Richard Garriott and his two Russian colleagues made a ‘flawless’ landing in Kazakhstan today, on their return from the International Space Station.

They avoided a string of mishaps that have plagued the Soyuz spacecraft on previous landings.

Cosmonauts Sergei Volkov and Oleg Kononenko, as well as American space tourist Richard Garriott, said they were ‘feeling well’. They were extracted from the capsule by a Russian recovery team.

Mr Garriott, the U.S. video game guru, who paid £17 million for his 10-day jaunt looked elated after his trip.

'What a great ride that was,' said Garriott.

Sitting in an armchair and wrapped in a blue blanket against the near-freezing temperature on the steppe, he smiled broadly.

From The Daily Mail:

The first astronauts sent to Mars should be prepared to never return to Earth, according to moonwalker Buzz Aldrin.

Like the European pioneers who set out for America they should set out knowing they will spend their lives there, the second man on the Moon said. Though presumably they would hope to survive longer than their first harsh winter.

In an interview the outspoken former astronaut said the Red Planet, which appears to have fast reserves of frozen water at each pole, has far greater potential for habitation than the Moon.

'It is nearer terrestrial conditions, much better than the Moon and any other place,' the 78-year-old said.

Goce Gravity Flight Slips To 2009

From The BBC:

Europe's gravity mission has been bumped to next year because of ongoing technical problems with its launcher.

The arrow-shaped Goce satellite will map tiny variations in the pull of gravity experienced across the world.

The information will give scientists a clearer insight into how the oceans move, and provide a universal reference to measure height anywhere on Earth.

But concerns about the reliability of its Russian rocket mean a lift-off is now unlikely before February.

It is a frustrating delay for the Gravity Field and Steady-State Ocean Circulation Explorer (Goce).

The satellite was already two years behind schedule when it was sent to the launch pad because engineers had to work through immense technical difficulties in building it.

The super-sleek spacecraft was due to go into orbit on a modified intercontinental ballistic missile, known at the Rockot, from the Plesetsk Cosmodrome in north-west Russia in the spring.

From Space Daily:

Russia's spacecraft producer Energiya will not provide any more Soyuz vessels for trips to the International Space Station unless funds could urgently be found, Energiya's president and general constructor warned Friday.

"We have vessels and funding for them for the next two trips, but I do not know what will happen with expeditions after that," Vitaly Lopota told reporters as quoted by the RIA Novosti news agency.

"We have no funds to produce new Soyuz craft. Unless we are granted loans or advance payment in the next two or three weeks, we cannot be responsible for future Soyuz production," Lopota explained.

The Soyuz is Russia's workhorse spacecraft that has carried out more than 1,600 flights, despite glitches that have bedevilled recent landings of the Soyuz capsule.

Space Programs Poised for Major Expansion in Asia

From National Defense Magazine:

SAPPORO, Japan — Japan’s government is about to kick off a major expansion of the nation’s space programs. The goal is to broaden the scope of space research from traditional areas such as exploration into new military and commercial applications.

The intent is to boost the country’s space industry and, over time, become less dependent on foreign suppliers such as the United States.

“There was a huge inferiority complex for the Japanese industry, that we needed to catch up with the top-level, state-of-the-art technology,” says Hokkaido University associate professor Kazuto Suzuki.

These goals would have been unrealistic until Japan’s legislature passed a law that for the first time creates a dedicated space bureau — run by a controversial politician, Seiko Noda.

“They knew they had to change their space law and their space organization because they were not structured and organized in order to compete in the 21st century,” says Vincent Sabathier, senior fellow and director of space initiatives at the Center for Strategic and International Studies in Washington.

The Japanese government beginning in the 1970s invested 4 trillion yen into research and development projects, including satellites, rockets, launchers, exploration spacecraft, and most recently, Kibo, the experimental module that was installed aboard the International Space Station this summer.

For U.S. Astronauts, A Russian Second Home

From The New York Times:

STAR CITY, Russia — Garrett Reisman was on his way to this formerly secret military base for several weeks of training, making his way through Kennedy Airport, when his cellphone rang. It was his boss, Steven W. Lindsey, the head of NASA’s astronaut office.

“Come back to Houston. They’ve canceled your training — they’re playing hardball,” Mr. Reisman recalled his boss saying. He was caught in a momentarily important dispute between NASA and the Russian space agency, Roscosmos.

Ultimately, Mr. Reisman’s aborted trip was just a bump in the road on the way to space: he spent three months aboard the International Space Station earlier this year, performed a spacewalk and even traded jokes over a video link with Stephen Colbert.

Everyone who works with the Russian space program has similar stories to tell of implacable bureaucrats, byzantine rules and decisions that seem capricious at best. And many of those stories are played out here in Star City, where cosmonauts and, now, astronauts from all over the world train to fly on Russian Soyuz spacecraft to go to the $100 billion International Space Station.

New Spacecraft to Explore Interstellar Boundary -- Popsci

IBEX Mounted on Pegasus: Photo courtesy NASA

NASA's IBEX craft is heading out this month to map the edges of the solar system

The "termination shock" sounds like the stuff science fiction movies are made of. In reality, it marks the boundary between our solar system and interstellar space. The invisible "shock" forms as our sun's solar winds begin to encounter the gases and magnetic fields of outer space, which slows the winds down abruptly.

On October 19, NASA will launch the first spacecraft designed to image and map the interactions that take place in this boundary zone. The Interstellar Boundary Explorer, or IBEX, will be propelled from the Kwajalein Atoll into a high-altitude orbit that will eventually take it about 200,000 miles from Earth, where it will capture images of processes taking place in the termination shock and beyond.

"The interstellar boundary regions are critical because they shield us from the vast majority of dangerous galactic cosmic rays, which otherwise would penetrate into Earth's orbit and make human spaceflight much more dangerous," said David J. McComas, principal investigator of the IBEX mission and senior executive director the Space Science and Engineering Division at the Southwest Research Institute.

Spacecraft Reveals Stunning New Views of Mercury

The features this image from MESSENGER's Oct. 6, 2008 flyby shows never-before seen terrain. The region in the foreground near the right side of the imag is close to the border between darkness and daylight, so shadows are long and prominent. Two very long scarps are visible in this region, and the scarps appear to crosscut each other. The easternmost scarp also cuts through a crater, showing that it formed after the impact that created the crater. Other neighboring impact craters, such as in the upper left of this image, appear to be filled with smooth plains material. Credit: NASA/JHUAPL/CIW. (Photo from Live Science)

From Live Science:

A NASA probe has begun beaming back stunning new images from its successful second flyby of Mercury, the planet closest to the sun.

NASA's MESSENGER probe captured never-before-seen views of the Mercury during its encounter on Monday. The spacecraft zipped past Mercury for the second time this year and used the planet's gravity to adjust its path as it continues en route to become the first probe to orbit the planet in March 2011.

One new image shows large patterns of ray-like lines extending southward across much of the planet surface from a young, newly-imaged crater. The previously-imaged Kuiper crater and others craters also have similar webs of lines radiating outward.

From Reuters:

WASHINGTON (Reuters) - A car-sized NASA spacecraft zoomed above the surface of Mercury on Monday, viewing rocky terrain never before seen up close on our solar system's sun-baked innermost planet, scientists said.

The MESSENGER probe flew as low as 124 miles near the equator of Mercury as part of its ongoing exploration of the planet nearest the sun, said project scientist Ralph McNutt of Johns Hopkins University Applied Physics Laboratory.

Initial images sent back to Earth showed newly discovered cliffs on Mercury's surface, with the bulk of the data to be transmitted on Tuesday, McNutt said.

"This is all covering about 30 percent of the planet that has never been seen by a spacecraft before," McNutt said in a telephone interview. "As far as we can tell, everything executed just as it was supposed to."

This was the second of three scheduled encounters before MESSENGER enters into orbit around Mercury in 2011. It flew past Mercury on January 14 and will return in September 2009.
