Monarch butterflies flying in space [Invertebrates, Astronomy, space, Biology] — Administrator @ 1:04 am


This video is from when the monarchs on the ISS were still caterpillars.

From Space.com in the USA:

The first-ever Monarch butterflies in space have taken flight on the international space station to the delight of astronauts aboard. …

The Monarch butterflies are the first ever sent to space. They began emerging just days after several Painted Lady butterflies began emerging from their own cocoons in a separate enclosure.

The Monarch and Painted Lady butterflies arrived at the station as catepillars last month on the space shuttle Atlantis as part of an educational experiment. And while butterfly larvae have been sent to space before, the colorful insects on the space station now are the first to successfully go through all phases of their development — from larva to pupa to adult butterfly — in orbit. …

At least one difference between space Monarch butterflies and their terrestrial counterparts has already been revealed. On Earth, the wings of a newly-emerged Monarch butterfly can take anywhere between three and five minutes to dry. But aboard the space station, it took about 15 minutes. …

Because of the cramped quarters, the Monarch butterflies — which began emerging Nov. 30 — were only expected to live about four days, instead of the two weeks they would survive on Earth, NASA officials said. The space Painted Lady butterflies, meanwhile, are expected to live about a week, about half what they would on Earth.

The butterflies are not the first critters to live among the human crew of the International Space Station. Two orb weaving spiders managed to spin wild webs in weightlessness last year, with astronauts checking in on them from time to time.

Deepest universe photo ever

From Space & Astronautics News:

The new Wide Field Camera 3 aboard the NASA/ESA Hubble Space Telescope has taken the deepest image yet of the Universe in near-infrared light. The faintest and reddest objects in the image are likely the oldest galaxies ever identified, having formed between only 600-900 million years after the Big Bang. - ESA

Painted lady butterflies emerge in space [Invertebrates, Astronomy, space, Biology] — Administrator @ 8:45 pm


This video from the USA is called Painted Lady, Flight, Food feeder, 11-18-09, BioServe’s “Butterflies in Space” Experiment (from when the butterflies were still caterpillars).

By Ian O’Neill, Discovery News:

For the first time in history, two butterflies have survived the chrysalis stage of development and spread their wings as fully grown Painted Lady butterflies in microgravity.

Although many species of insects have boldly gone where no insect has gone before, this is the first occasion that a butterfly has survived the larvae phase, gone on to form a chrysalis and then emerge as a mature butterfly.

This International Space Station (ISS) outreach experiment is organized by BioServe Space Technologies and the University of Colorado for students on the ground to follow the progress of the orbiting creatures. The school kids can then compare the development of butterflies in the classroom with their orbiting cousins.

‘American megafauna not killed off by Clovis people’ [Plants etc., Environment, Mammals, Astronomy, space, Biology, Archaeology] — Administrator @ 4:53 pm

This video from the USA says about itself:

In 2005, fossilized mastodon remains were discovered in Pratt’s Wayne Woods Forest Preserve in Wayne. During the course of a habitat-improvement project, a contractor for the Forest Preserve District of DuPage County made an initial discovery – teeth from a mastodon. With help from the Illinois State Museum, a science team visited the site to search for more fossils. This search unearthed a partial rib and pieces of bone and tusk. Watch the video to learn about the initial discovery.
From Discover Magazine:
Spores in Mastodon Dung Suggest Humans Didn’t Kill Off Ancient Mammals

A fungus found within ancient mammoth dung

Dear Discover Magazine, was it mastodon dung or mammoth dung? Though both are related to elephants, they are not the same species or genus. The BBC is also confused about this.
is providing scientists with clues about how the large ancient mammals collectively known as megafauna went extinct. The fungus, Sporormiella, produces spores in the dung of large herbivores. These are then preserved in the layers of mud and can provide an index of the number of these animals, or megafauna, that roamed the environment at a particular time [BBC News]. For a new study, researcher Jacquelyn Gill collected and analyzed spores in sediment samples from an Indiana lake and several sites in New York.

From Gill’s analysis, published in the journal Science, she concluded that North American megafauna began a slow decline around 15,000 years ago and vanished about 1,000 years later. The data suggests megafauna started going extinct much earlier than previously though, which basically wipes out two theories of their extinction.

There are several theories surrounding the extinction of North American megafuana, but there are a lot more questions than answers. Much of the uncertainty surrounding the extinction of the North American megafauna, which includes mastadons, saber-tooth tigers and giant ground sloths, is due to a scarcity of evidence and difficulty pinning down the timing of events. Several major events occurred around the same time the animals disappeared: Major environmental upheaval associated with the end of the Ice Age; an asteroid explosion over North America; and the arrival of man [Wired.com]. But the new data points to an extinction culprit other than an asteroid or comet impact, because the impact is believed to have occurred long after the megafauna began their decline.

If humans were responsible for the extinction, it would have to be settlers that came along before the Clovis people, which is another debate in itself. The Clovis culture is thought to have been the first civilization to take hold in North America around 13,300 years ago–after the bulk of the megafauna extinctions, according to the new analysis. But some researchers believe that earlier settlers walked the land before the Clovis people, and could have hunted the mastodons and mammoths. The new study adds crucial info to the fossil record, but it is likely to kindle, rather than quench, the debate over megafauna extinction.

Next shuttle mission will carry butterflies to space for classroom science experiments

By John Matson

Butterflies on the ISS Space shuttle Atlantis, set to lift off November 16 for the International Space Station, will launch with more than just its six-member astronaut crew onboard. Stowed away in a biological payload module will be larvae of two species of butterfly, whose development students on the ground will track from their classrooms.

For the experiment, formally designated CSI-03, about 100 K–12 schools in the U.S. will receive habitat kits, according to a press release from the University of Colorado at Boulder, where the space-bound payload was developed. Students will be able to observe the butterflies’ metamorphosis up close on Earth and compare their development to the insects in the weightless environs of the space station. (Images of the station’s butterflies will also be posted for public viewing at BioEd Online.)

The monarch and painted lady butterflies won’t be the first insects, or even the first butterflies, flown in space—past experiments have also included bees, ants and silkworms.

As for the rest of the 11-day STS-129 mission, Atlantis will deliver a slew of parts to the station as the U.S. seeks to wrap up the station’s construction and retire the space shuttle. After STS-129, only five shuttle missions remain on the launch schedule, all of them to the International Space Station.

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.
