Chinese space pioneer dies [Human rights, Astronomy, space] — Administrator @ 10:02 pm


This video is called H.S. Tsien [Qian Xuesen]: Father of rockets and spaceflight.

From British daily The Morning Star:

Father of space programme dies

Qian Xuesen, the father of China’s space technology programme, died on Saturday in Beijing. He was 98.

Mr Qian began his career in the US and was regarded as one of the brightest minds in the new field of aeronautics before returning to China in 1955, hounded out of the United States for his alleged membership of the CPUSA.

He went on to establish China’s first missile and rocket research institute which later helped start China’s space programme, led the development of China’s first nuclear-armed ballistic missiles and worked on its first satellite, Red East 1, which was launched in 1970.

US Air Force spying hinders astronomy [Peace and war, Astronomy, space, Physics] — Administrator @ 1:21 pm


This video says about itself:

The Laser Interferometer Gravitational Wave Observatory is spearheading the completely new field of gravitational wave astronomy and opening a whole new window on the universe.

LIGO’s exquisitely sensitive instruments may ultimately take us farther back in time than we’ve ever been, catching, perhaps, the first murmurs of the universe in formation.

From New Scientist in the USA:
Astronomers clash with US air force over laser rules

* 22:29 13 October 2009 by David Shiga

Could astronomers accidentally blind Earth-observing satellites? That seems to be the worry of the US air force, which restricts the use of lasers pointed at the sky to help focus telescopes. But some astronomers warn they will miss key observations under the rules, which have tightened in recent years.

Many of the world’s largest observatories, including Lick, Gemini North, Palomar and Keck in the US, shine lasers into the sky to measure atmospheric turbulence, which distorts images.

The laser causes a layer of sodium atoms at an altitude of about 90 kilometres to glow, producing an artificial star whose twinkles reveal the turbulence. Shape-shifting mirrors on the telescopes, called adaptive optics, then correct for the blurring by adjusting their shape many times per second.

If such a laser were to hit the optics of an Earth-observing satellite, it could cause damage. So the air force’s Space Command has for years restricted when and where US observatories can fire them, and the observatories have voluntarily complied, with little impact on astronomy.

Then about two years ago, just as kinks in the laser technology were being ironed out and interest in the lasers was growing, the rules were tightened. Now astronomers say the restrictions are beginning to chafe, according to a story first reported by the American Physical Society.

“Significant negative impacts of these new restrictions on scientific productivity are being felt,” says a 2008 report (pdf) by the US Association of Universities for Research in Astronomy, which is based in Washington, DC.

Raytheon censors Antarctic bloggers [Peace and war, Economic, social, trade union, etc., Human rights, Visual arts, Computers, Internet, Astronomy, space, Biology, Medicine, health] — Administrator @ 12:41 am

This video is the documentary “Visiting Antarctica”.

From Denver News in the USA:

Life in Antarctica is cold — but bloggers there can still get burned

By Jonathan Shikes

Published on October 06, 2009 …

The United States has three permanent stations in Antarctica — McMurdo, Amundsen-Scott South Pole and Palmer — and conditions there are tough, especially during the winter (our summer), when it’s dark 24 hours a day. The crew members have to be very careful when they go outdoors, and the constant darkness robs them of their normal circadian rhythms and the vitamin D that humans need. After a few months on the ice, many of them develop a condition they call “brain freeze,” in which they start mumbling, and it can take seconds, even minutes, to complete a thought or form a cohesive sentence.

The three stations are operated by Raytheon Polar Services, a Centennial-based division of Raytheon, the $23.2 billion, multinational defense contractor that has 73,000 employees worldwide. Raytheon won the ten-year, $1.12 billion Antarctic Support Contract from the National Science Foundation in 1999 and reapplied this year, but it’s facing competition from six other conglomerates that have spent millions of dollars just to prepare their bids. The new, thirteen-and-a-half-year contract is valued between $1.5 and $2 billion; it was supposed to be awarded October 1, but the NSF recently delayed its decision without explanation.

The contract involves not just supporting the NSF’s scientific research — on climate change, astronomy, biology and atmospheric and environmental science — that has to be justified to Congress and to taxpayers, but also constructing and maintaining the buildings and equipment at the U.S. bases, providing water production and fuel operations, planning missions, transporting personnel and cargo, and maintaining communication. The contractor must also hire, train, feed, house, pay and protect the small army of support staffers who live in Antarctica, whether for five months or twelve, keeping them alive, warm, fed and happy.

That’s not always easy, as Raytheon has discovered. …

Bloggers have also criticized Raytheon and its corporate policies. As a result, say a number of current and former employees, Raytheon has cracked down both on blogging and on some of Antarctica’s odder traditions — particularly as the new contract deadline approaches.

“What is most disturbing is the censorship,” one Raytheon employee says in an e-mail. “We are told to never speak to the press. Raytheon fears a PR black eye and doesn’t want things to get out. Two people who are blogging down here have been told to stop.”

Raytheon spokeswoman Valerie Carroll says the company has no anti-blogging policies, but employees insist that posts are closely watched and that critical ones have resulted in retaliatory actions. …

Midwinter’s Day is a tradition that dates all the way back to 1898, when the crew of the Belgica became the first people to spend the winter in Antarctica after the Belgian ship got stuck in the ice. Since then, the day has been celebrated to some degree by nearly everyone who’s spent the coldest month on the Continent, including explorers like Ireland’s Ernest Shackleton in 1907, Norway’s Roald Amundsen in 1911, and American Richard Evelyn Byrd in the 1940s. …

In 2008, Raytheon canceled the extra day off.

The decision wasn’t explained, and on June 11, 2008, blogger Nick Johnson posted the following message on his site, BigDeadPlace.com: “For those who haven’t heard, someone in Denver has decided that U.S. Antarctic stations this year won’t have the day off for Midwinter’s Day dinner (June 21st). No big deal. However, coincidentally, on June 21, [Raytheon Polar Services] is sponsoring, for its 250+ employees in the office, a ‘Summer Picnic’ at a Denver-area amusement park called Elitch Gardens, including a picnic and a Randy Travis concert.”

This wasn’t the first time that Johnson, a heavy equipment operator at McMurdo, had been critical of his employer. …

Johnson managed to remain employed after the book came out, and he started signing his name to his blog. And in May 1998, he began posting questions from Raytheon’s anonymous suggestion box, along with management’s answers. The exchanges seemed innocuous enough — but not to Raytheon. So instead of partying on Midwinter’s Day in 2008, Johnson was called in for a teleconference with Sam Feola, the program director for Raytheon Polar Services.

“He told me I had made some blog posts that involved ’sensitive information,’” Johnson remembers. “I didn’t say I would take anything down, I didn’t say I wouldn’t, but I asked, ‘What information, specifically, do you want me to take down?’ He replied, ‘All the information.’ I wasn’t going to do that.”

Although Johnson had worked in Antarctica off and on for a decade, Raytheon didn’t renew his contract for the following year. “I was blacklisted,” Johnson says. “That’s how it works. No one is surprised.”

Raytheon, which kept its Antarctic headquarters in the Denver area after taking over from ASA in 1990, has 354 employees in Centennial, including Feola, who declined to be interviewed for this story. …

Still, the perceived censorship, along with the cancellation of Midwinter’s Day in 2008 and other issues, remain a concern. “I have seen a big change in the way the companies have handled morale over the years,” the employee, who also has a blog, says. “When I started, there was a big recreation department, dedicated to keeping us happy and busy. This winter there was zero recreation, at least fostered by the company or NSF. I used to tell my non-ice friends that the USAP program went out of their way to provide good morale to cut down on random drinking and negativity. There is no sign any more that anyone cares about that at all, at least in the winter.”

“One of the most fun things we used to do is Bingo. We’d sell Bingo tickets for a buck or two, and the winners would get small cash prizes. My understanding is that Raytheon put an end to that, saying it was immoral.”…

When Johnson started BigDeadPlace.com in 2002, he knew of no other blogs about Antarctica. “Pre-Internet, there were a bunch of photocopied underground newsletters that people had made. Two important ones were called The Shadow and The Antarctic Moon, from the early ’90s, I believe,” Johnson says in an e-mail from Afghanistan, where he now works for another private contractor. Because of that, he adds, BigDeadPlace.com got a lot of attention. …

Today there are dozens and dozens of Antarctica blogs — written not just by Raytheon employees, but also by scientists and people who work on bases owned by other countries. Some of them detail daily life, while others focus on science or photography. Examples include:

Antarctiken.com, from Ken Klassy, a systems admin at McMurdo who posts his gorgeous photos, but also details his daily successes and frustrations.

Icewishes.wordpress.com, which follows the life of a “peripatetic redhead” at the South Pole.

60south.com, which focuses on art and photography at the bottom of the world, but also features a discussion board and other links.

Vagabumming.com, a view from Palmer Station.

Harriettstomato.com, an unusual look at the life of a cook at the South Pole. …

Like most major corporations, Raytheon has a social media policy, but Carroll declines to offer any specifics. …

A Raytheon employee provided the specifics of the social media policy, which begins: “Raytheon Company recognizes that employees may wish to create, maintain, and participate in external social media tools such as blogs, wikis, chatrooms, podcasts, microblogging (e.g., Twitter), discussion boards, and participate in social websites such as Facebook, MySpace, YouTube, LinkedIn.” …

But while the policy says the company “respects its employees’ rights to personal expression,” it also warns that Raytheon retains the right to “direct an employee to refrain from commenting on topics related to the Company or, take steps to remove or mitigate exposure of the offending material on the social media tool, to comply with applicable laws…and/or Company policy.”

While Raytheon’s weapons kill, inter alia, Iraqi civilians, its workers in Antarctica have participated in the worldwide demonstrations against the Iraq war in February 2003.

After Anne Frank asteroid, Miep Gies asteroid [Racism and anti-racism, Literature, Astronomy, space] — Administrator @ 11:17 am


This video is called Miep Gies: Giving Anne’s diary to her father.

From Dutch NOS TV:

Asteroid named Miep Gies

An asteroid has been named after Miep Gies, the woman who saved Anne Frank’s diary. The International Astronomical Union has said so. The asteroid Miepgies is rocky and has a 7 kilometer diameter.

Miep Gies (now 100 years of age) helped the Frank family to hide during the Second World War. After the inhabitants of the Secret Annexe had been arrested, she found the diary and hid it.

In the Netherlands, asteroids have been called after, eg, the author Hella Haasse, the Nobel prize winner Gerard ‘t Hooft, and Anne Frank herself.

Moon colder than Pluto [Astronomy, space, Physics] — Administrator @ 11:28 am


From New Scientist:

Moon is coldest known place in the solar system

* 17:02 18 September 2009 by MacGregor Campbell

Poor Pluto. First it gets kicked out of the planet club, now it’s not even the coldest place in the solar system. Dark craters near the moon’s south pole have snatched that title – which is good news for the prospects of finding water ice on Earth’s companion.

The craters’ towering rims block the sun from reaching their centres, like the long shadows cast by tall buildings at dusk. In this permanent darkness, they stay at a constant -240 °Celsius – more than 30 °C above absolute zero and 10 °C cooler than Pluto, which was measured at -230 °C in 2006.

“The lunar south pole is among the coldest parts of the solar system and may be in fact colder than what we expect from places like Pluto,” NASA scientist Richard Vondrak said at a press conference on Thursday.

The cold temperature bodes well for the prospect of finding water ice deposits in the moon’s shadowy pockets. Previous calculations had shown that water and other volatile gases would dissipate into space at temperatures above about -220 °C.

Wildfires threaten Californian astronomical observatory [Disasters, Crime, Astronomy, space] — Administrator @ 10:26 pm


From New Scientist in the USA:

California fire threatens historic observatory

* Updated 18:05 31 August 2009 by Kelly Beatty, SkyandTelescope.com, and Maggie McKee

A rampaging fire in the Angeles National Forest in southern California is threatening a historic observatory at the summit of Mount Wilson, as well as a dense crowd of television transmitters there.

The “Station Fire” fire began on Wednesday afternoon but has spread quickly, doubling in size overnight, to an area covering more than 345 square kilometres. With tongues of flame stretching about 25 metres long, the fire is only 5 per cent contained and will likely take another week to contain completely.

By Sunday evening, it had moved to within 3.2 km of Mount Wilson Observatory. On Monday, fire officials said fire had not reached the area, but they said the area still remained highly vulnerable.

Observatory staff reported at 0750 PDT (1450 GMT) on Monday that fire fighters had been ordered to withdraw from Mount Wilson, although the staff was not clear on why the decision had been made. Fire fighters were reportedly going to remain close by, within 8 kilometres away.

Throughout the day on Sunday, crews cleared tinder-dry brush from around the observatory complex and treated wooden structures to make them less vulnerable.

Historic discoveries

Located at an altitude of 1740 metres, Mount Wilson Observatory got its start in 1904 when George Ellery Hale signed a free, 99-year lease for 40 acres at the summit to build world-class telescopes.

Then Hale erected the Snow Solar Telescope (1905), a 60-inch reflector (the world’s largest when completed in 1908), the 150-foot Solar Tower, and finally the 100-inch Hooker Telescope (1918), which Edwin Hubble used to discover that the universe is expanding.

Despite being swamped with light pollution from the 13 million residents to its immediate south and southeast, the observatory has regained much of its scientific relevance.

In recent years, Mount Wilson has served as a test-bed for adaptive-optics and interferometric imaging. It’s the main facility of Georgia State University’s Center for High Angular Resolution Astronomy (CHARA) and the site of the University of California’s Infrared Spatial Interferometer (ISI).

Closed NASA site

Over the weekend, the Station Fire also kept NASA’s Jet Propulsion Laboratory closed to all non-critical personnel. Officially, JPL is in Pasadena, California, but technically it’s in the town of La Cañada Flintridge, which has been posting hourly updates about the rapidly spreading inferno.

Building observatories on remote mountaintops places them at great risk from forest fires, especially where climates have turned dryer in the last decade or two.

This is not the first time Southern California’s notoriously frequent conflagrations have threatened a major astronomical facility. In November 2007, the Poomacha Fire came near, but did not damage, Palomar Observatory. Likewise the University of Arizona’s Steward Observatory had a close call during the Aspen Fire in June 2003.

Australia’s Mount Stromlo Observatory wasn’t so lucky – it was totally destroyed by a wildfire in 2003.

Banned books exhibition [Human rights, Religion, Literature, Astronomy, space, Biology, Medicine, health] — Administrator @ 6:16 pm

This video from the USA says about itself:

Avila Fine Arts Lovers Hostess Sherry Avila interviews Curator, Dr. Roberto Severino, Professor Emeritus, Italian Department of Georgetown University, D.C., about Science and Faith Between Observance and Censorship: Rare Books from the Libraries of Campania from XVI to XVIII Centuries. This exhibition of the Roman Catholic Church’s Index of Forbidden Books (librorum prohibitorum) and rare volumes listed in the Index from 1550 to 1750 focuses on scientific and religious books banned by the Church following the Counter Reformation. Often beautifully illustrated, these volumes are written by famed authors such as Girolamo Cardano, Copernicus, Duns Scotus, Euclid, Galileo and Girolamo Savonarola.

Curated by Dr. Roberto Severino, Professor Emeritus of Classical History at Georgetown University, and Dr. Loredana Conti, Superintendent of Libraries, Regione Campania, Italy, the exhibition includes books from the Biblioteca Universitaria di Napoli, Biblioteca Provinciale di Salerno, Biblioteca S. Francesco del Convento di San Francesco and Biblioteca Landolfo Caracciolo. Organized by Regione Campania and Italian Muse. Sponsored in part by the Italian Cultural Institute.

Cortona spotlights banned books

Ovid, Boccaccio, Galileo, Darwin in Tuscan town

Cortona, August 28 - This Tuscan town is hosting an exhibition in celebration of historic books outlawed during their day for their radical sexual, religious, political and scientific ideas. I Libri Proibiti (The Forbidden Books) showcases over 40 volumes dating from the 16th to the 20th centuries, on loan from collections belonging to London’s renowned antiquarian bookseller, Quaritch, and Italy’s Giangiacomo Feltrinelli Foundation. …

The Satyricon, a banned book by French alchemist and physician Nicolas Barnaud, contains a painstakingly detailed and accurate list of the mistresses, prostitutes, illegitimate children and servants of churchmen in every diocese of 16th-century France.

An English-language Koran published in 17th-century London, translations of Ovid’s Ars Amatoria and detailed Renaissance anatomical studies, drawn from outlawed human dissections, are among the other forbidden works on display.

The exhibition, divided into themes, draws out developments in thought over the centuries.

In particular, it points out that the Catholic Church’s register of banned publications, the Index Librorum Prohibitorum, is practically a Who’s Who of modern Western thought. Works by Galileo Galilei, Dante Alighieri, Nicolaus Copernicus, Giovanni Boccaccio and Charles Darwin all appeared on the register at some point during its 400-year history. The exhibition can be visited at Palazzo Vagnotti until September 6.
