Chilean Quake May Have Shortened Earth Days
This view of Earth comes from NASA's Moderate Resolution Imaging Spectroradiometer aboard the Terra satellite.
The Feb. 27 magnitude 8.8 earthquake in Chile may have shortened the length of each Earth day.
JPL research scientist Richard Gross computed how Earth's rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second).
Perhaps more impressive is how much the quake shifted Earth's axis. Gross calculates the quake should have moved Earth's figure axis (the axis about which Earth's mass is balanced) by 2.7 milliarcseconds (about 8 centimeters, or 3 inches). Earth's figure axis is not the same as its north-south axis; they are offset by about 10 meters (about 33 feet).
By comparison, Gross said the same model estimated the 2004 magnitude 9.1 Sumatran earthquake should have shortened the length of day by 6.8 microseconds and shifted Earth's axis by 2.32 milliarcseconds (about 7 centimeters, or 2.76 inches).
Gross said that even though the Chilean earthquake is much smaller than the Sumatran quake, it is predicted to have changed the position of the figure axis by a bit more for two reasons. First, unlike the 2004 Sumatran earthquake, which was located near the equator, the 2010 Chilean earthquake was located in Earth's mid-latitudes, which makes it more effective in shifting Earth's figure axis. Second, the fault responsible for the 2010 Chiliean earthquake dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake. This makes the Chile fault more effective in moving Earth's mass vertically and hence more effective in shifting Earth's figure axis.
Gross said the Chile predictions will likely change as data on the quake are further refined.

Lomo LC-A+ Camera Goes High-End With 24-Carat Gold Finish [Cameras]
Lomo cameras (back in the day) were popular as they were cheap as chips and almost disposable, made from just flimsy plastic. Now, they're coated in 24-carat gold and in limited edition runs of 130 pieces.
It'll still produce the same dreamy photos full of saturated colors and vignetted corners, but at $600 a piece it'll probably be relegated to a dusty shelf than actually be used. Still, I definitely want one—especially now that I can spoil the aesthetic completely with Lomography's new instant back accessory for the LC-A+. [Lomography via Retro To Go]
Radar Map of Buried Martian Ice Adds to Climate Record
A radar on NASA's Mars Reconnaissance Orbiter has detected widespread deposits of glacial ice in the mid-latitudes of Mars. › Full image and caption
Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble.
The ability of NASA's Mars Reconnaissance Orbiter to continue charting the locations of these hidden glaciers and ice-filled valleys -- first confirmed by radar two years ago -- adds clues about how these deposits may have been left as remnants when regional ice sheets retreated.
The subsurface ice deposits extend for hundreds of kilometers, or miles, in the rugged region called Deuteronilus Mensae, about halfway from the equator to the Martian north pole. Jeffrey Plaut of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and colleagues prepared a map of the region's confirmed ice for presentation at this week's 41st Lunar and Planetary Science Conference near Houston.
The Shallow Radar instrument on the orbiter has obtained more than 250 observations of the study area, which is about the size of California.
"We have mapped the whole area with a high density of coverage," Plaut said. "These are not isolated features. In this area, the radar is detecting thick subsurface ice in many locations." The common locations are around the bases of mesas and scarps, and confined within valleys or craters.
Plaut said, "The hypothesis is the whole area was covered with an ice sheet during a different climate period, and when the climate dried out, these deposits remained only where they had been covered by a layer of debris protecting the ice from the atmosphere."
The researchers plan to continue the mapping. These buried masses of ice are a significant fraction of the known non-polar ice on Mars. The ice could contain a record of environmental conditions at the time of its deposition and flow, making the ice masses an intriguing possible target for a future mission with digging capability.
The Shallow Radar instrument was provided by the Italian Space Agency, and its operations are led by the InfoCom Department, University of Rome "La Sapienza." Thales Alenia Space Italia, in Rome, is the Italian Space Agency's prime contractor for the radar instrument. Astro Aerospace of Carpinteria, Calif., a business unit of Los Angeles-based Northrop Grumman Corp., developed the instrument's antenna as a subcontractor to Thales Alenia Space Italia.
The Mars Reconnaissance Orbiter mission is managed by JPL for NASA's Science Mission Directorate in Washington. Lockheed Martin Space Systems in Denver was the prime contractor for the orbiter and supports its operations. The California Institute of Technology in Pasadena manages JPL for NASA.

Salt-Seeking Satellite Shaken By Quake, But Not Stirred
NASA's Aquarius instrument, and the Argentinian spacecraft that will carry it into space, the Satelite de Aplicaciones Cientificas (SAC-D), successfully rode out one of the largest earthquakes in recorded history Feb. 27 with no problems. The instrument and spacecraft are at the satellite systems contractor's satellite integration facility in Bariloche, Argentina. The city of Bariloche, located approximately 588 kilometers, or 365 miles, from the epicenter of the magnitude 8.8 earthquake, experienced light shaking, as indicated by the Modified Mercalli Intensity Scale, which evaluates the effects of earthquakes as experienced by people in the region. No damage was reported to the facility or spacecraft. A separate magnitude 6.3 earthquake in Salta, Argentina, later that day that was triggered by the Chile earthquake was too far away (1,900 kilometers or 1,200 miles) to be felt in Bariloche. The JPL-built Aquarius instrument is at the Bariloche facility to be integrated with the SAC-D satellite.
Aquarius/SAC-D is an international mission between NASA and Argentina's space agency, Comisión Nacional de Actividades Espaciales. The primary instrument on the mission, Aquarius is designed to provide monthly global maps of how salt concentration varies on the ocean surface -- a key indicator of ocean circulation and its role in climate change. Seven Argentine space agency-sponsored instruments will provide environmental data for a wide range of applications, including natural hazards, land processes, epidemiological studies and air quality issues.
The minimum three-year mission is scheduled to launch late this year from Vandenberg Air Force Base, Calif.

Mars Odyssey Still Hears Nothing From Phoenix
NASA's Phoenix Mars Lander showed no sign during February that it has revived itself after the northern Mars winter. NASA's Mars Odyssey orbiter will check again in early April. The solar-powered Phoenix lander operated for two months longer than its planned three-month mission in the Martian arctic in 2008. It was not designed to withstand winter conditions. However, in case the return of abundant springtime sunlight to the site does revive Phoenix, Odyssey is conducting three periods of listening for a transmission that Phoenix is programmed to send if it is able. The second listening period, with 60 overflights of the Phoenix site from Feb. 22 to Feb. 26, produced the same result as the first listening period in January: no signal heard.

Volunteerism vs. Voluntourism: Are They Synonymous?
Ape meets woman, Photo by Claire Hamilton
A few years ago I joined a travel-related website while researching a trip to Panama. Some of you know will know it as Travellerspoint.com. I have spent quite a bit of my online time over there and one of the common questions posed in the forums deals with volunteerism. “This company charges $X,XXX for a 2 month program. Is that cheap?” or “Is this company on the up & up?” or “Shouldn’t volunteering be free as long as I get there? I’m volunteering, after all.” All good questions. Ones that make me think daily as I remember volunteerism as something you did not pay for, except your transportation to get where you were needed.
I was reminded of this, once again, when my husband and I introduced a close friend to an organization that is a sanctuary for injured and displaced wolves. At the time, the sanctuary offered room and board for a day’s work. BUT, they were considering charging fees “because most other volunteer organizations were doing it and raking in a profit”. Understandable when you are working at a loss. The sanctuary is still on a “room & board for work performed” basis. Combining my personal experience with the ones on Travellerspoint, I could not help but ask the “synonymous?” question.
So, I’m done pontificating and here are your replies:
Dave
This is a topic really hits me hard. I’ve worked as both a volunteer and as a staff member in a number of countries.
I’ve seen these two terms merge over the years and truly; I don’t like it. In practice, I have no issue with someone paying to go out and help somewhere. If they are qualified to do so, and if the organization is also as qualified.
There are thousands of organizations that come under the “NGO” banner that are merely set up to make money. This holds true for many non-NGOs too.
I’ve also seen college graduates leave, with great intentions, to help build houses and teach. For the former; manpower in many developing organizations is not an issue. Many are not qualified to teach, and end up doing more harm than good. Though, more often than not they will return feeling on top of the world for helping.
At the heart of this, I do not blame the volunteers. I blame the corrupt NGO’s and Government departments that allow them to run, and to an extent the parents paying for all this.
One such incident occurred in Nepal, where an English girl paid 7,000 USD to volunteer for 6 weeks at a monastery through an NGO. She was clueless before leaving. Once she arrived she discovered the Monastery takes anyone, for free. It was the NGO’s fees that she was paying.
Research your placement, country and job criteria before going. Ask non-profits for their account income & expenditure details. The really good ones will supply them to you for transparency reasons.
Yes, there are good volunteer organizations out there, but the criteria to get in is high. Another option is simply to go to a country you wish to help, knock on doors of agencies and see for yourself before truly volunteering.

No, you shouldn’t have to pay a fee to volunteer. Sites like i to i are just taking a middleman fee and pocketing most of the money anyway. True volunteer organizations don’t make you pay. You pay for your way there but you trade your time for room and board. There are no hidden fees. I recommend programs like Hands On Disaster Relief. I would never volunteer with an organization that made me pay. I’d rather just donate directly to the community than pay towards one of these programs.
Hannah Barth
Most diehard travelers are loathe to be called ‘tourists’. To me, the word ‘tourism’ denotes a disconnection with the world one is traveling in. Voluntourism, then, seems to be a way to feel good and do good, but not necessarily connect with the people or the place you’re traveling to. When you pay a fee to volunteer, you are, in essence, paying for the tourism aspect of your trip. You’re paying an agent to choose how to put you in contact with the local population as you’ve chosen not to do it for yourself.
Volunteering, on the other hand, can be done anywhere; in your hometown, home country, or abroad.
Volunteering, on the other hand, can be done anywhere; in your hometown, home country, or abroad. Because volunteering is less location-specific – down the street from where you live, for instance, where you probably wouldn’t travel on holiday – it’s always seemed like a very different thing than ‘voluntouring’. One may choose to travel and volunteer at the same time, but it’s self-guided. Volunteering while traveling then is more of an activity, like going to a museum or seeing a famous landmark. I, personally, strongly prefer the latter.
Jason Batansky
Tough question. I don’t think volunteerism and voluntourism should hold the same meaning because the experiences differ so much. While generalizations are never ideal, it’s appropriate to make some in comparing the two terms. Voluntourism is a vacation. The participants pay for the short-term (one week to a few months) experience of interacting with people they might not ordinarily meet. Their money used to fund the vacation helps the cause more than their personal efforts. In contrast, volunteers traveling abroad either donate an in demand skill (e.g. doctors) or their abundance of time (e.g. unskilled workers caring for children). They don’t pay for the opportunity to help because the organization they work with actually needs their help and not just their money. I have nothing against voluntourism nor volunteering. Some great opportunities can be found at http://www.Idealist.org.

It takes time to train a high-skilled volunteer, so what’s left for most of the kind-hearted tourists out there usually has more in common with a feel-good guided tour than real volunteer work. There’s nothing wrong with lending a hand on a trip, but for longer-lasting volunteer work with a profound effect, consider looking for longer-term placement – such as through Volunteer Services Oversea (UK), or the Peace Corps (US).
If you’re up for the task, get involved in social justice and help at home – there’s plenty of people in need there too!
Nora Dunn
Voluntourism (from my understanding) combines a volunteer experience with a tourism one. Tourists will pay for something along the lines of an all-inclusive vacation, which includes sightseeing as well as volunteering for a good cause. It is these sorts of organized volunteer tourism adventures that also cost a pretty penny.
Volunteerism technically simply refers to the act of volunteering, which we can do at home or abroad, with no reference in the definition to travel.
Despite popular opinion, there are still lots of ways to volunteer your services and not have to pay hefty fees for that privilege. In some cases, accommodation can be subsidized or even paid for in return for your volunteer work. However you’ll have to hunt around for these opportunities; the big businesses promoting voluntourism adventures often have better search results rankings.
Steve Shoppman
With the many organizations charging fees to volunteer, I believe they are doing the right thing as they are providing a service to tourists looking for a different experience. Anyone who is really making a difference needs to spend considerable time there to even begin to help the people. For those tourists volunteering, they are reaping far more benefits from their time than the people they are helping.
This is not to say this is a bad thing, if more people were paying to volunteer I think they would certainly get more out of their travel experiences as they would be spending quality time directly interacting with the people in the country they are visiting. The organizations that allow this really are providing a service to the tourist rather than the other way around, and the tourist should be happy to pay money for an experience that is most certainly worth more than the lame tours you might pay for on a vacation.
Carl Beien
Having been on both sides of the “voluntourism” experience, we can only hope that the practice continues to grow. While pay-to-play “volunteer” positions may seem at first disingenuous, run well, the practice can be highly beneficial for all parties involved.
Anyone having spent time volunteering abroad knows how little impact a short stint can have.
Anyone having spent time volunteering abroad knows how little impact a short stint can have. A few days, weeks, or even months, especially without being fluent in the local language, is not nearly enough time for an individual to accomplish much of a lasting change. It is enough time, however, for a person to develop a lasting connection to a place – more than just, “they were a friendly people with good food”.
Furthermore, tourists looking for a more satisfying experience can bring well-needed dollars to organizations trying to do good work, but strapped for cash. Instead of hopping around a country putting money into often dubious pockets, encouraging behaviors like false hospitality and helping build stereotypes of Westerners as rich party seekers, “voluntourism” allows tourists to get a deeper, more intimate look at a culture, all the while ensuring their foreign dollars go to a good cause.

If a person has to pay money to work, then their work must not be of enough value to stand on its own. Paid volunteering is tourism, you are paying to have an experience: rather than going on a rafting trip or a pub crawl you are shown poor people and provided with the feeling that you helped them. I don’t know what else an unskilled person from a rich country really has to offer anybody besides their money anyway.
If your help was really needed you would be invited to share your skills and knowledge based on their own merit, not the money in your pocket. This is called volunteering.
It is my impression that voluntourism is a very frightening industry that is essentially transforming poverty into a commodity that can be sold to tourists for thousands of dollars. The leeway for scams and con artists is very wide. If you think your money is going to the people you are trying to help, guess again — see past the flowery websites and the pictures of smiling poor children — this is a business, and the poor are the commodities (the meeker the better). Where there is money to be made you will find profiteers making it.
Volunteers that really have something to offer are only worth the value of what they have to teach.
Volunteers that really have something to offer are only worth the value of what they have to teach. Unfortunately, the profiteers have found that the droves of unskilled tourists willing to pay money for the title of “volunteer” are worth far more money that the real volunteers themselves. If someone demands that you pay money to help them, then your help is not what they are after.
Derek Turner
Hmm, let’s see… soapbox or no soapbox? To volunteer is simply to offer a service without a price. A person can do that in their own neighborhood. Voluntourism, however, can be more industry than service. The two are related, but they are certainly not synonymous.
I left my career to sail around and “change” the world, and didn’t know what to expect. I started with a website to raise funds, 100% of which went towards helping meet needs I saw along the way. When I made efforts to contact “volunteer” organizations, ready and willing to help, I realized for the price tag attached the money could go much further if I did it myself.
I guess the bottom line is if “voluntouring” actually makes a difference in the life of someone less fortunate, then I’m for it. If someone is going to spend a fortune on vacation, but decides instead to “rough it” for a week or two, and do some voluntouring to make a difference, then why not? But… I have to admit there is something deep down inside that cringes when a company tries to capitalize on a person really wants to volunteer his or her time or skill to truly help.
Burt Rutan’s BigThink
The web site Big Think has posted an extended interview with Burt Rutan, who talks about space tourism, innovation in NASA and the private sector, and other topics. I haven’t watched the full one-hour interview in its entirety yet, but in the portions I’ve watched he covers some familiar ground about the utility of space tourism and the innovation—or lack thereof—he sees at NASA today compared to the space agency of the 1960s:

Nokia's picked the beta version of the Skype app up off the floor, dusted it off, and granted it a shiny new spot in its Ovi Store, for all Symbian^1 phones. Your network can kiss goodbye your money.
It works over Wi-Fi or a data connection on these handset models: Nokia E71, N96, N85, 5320, 6210 Navigator, 6220 classic, N78, N79, E63, E66, N82, E51, N95, N95 8GB, N81, N81 8GB, E90, E72, 5800 XpressMusic, N97, N97 mini, X6, and the 5530.
While it only works on Nokia handsets at the moment, Skype plans on launching the app on other manufacturers' Symbian phones, with Sony Ericsson next in line to get the free Skype-to-Skype calls, IM ability and sharing files functionality. It's available now through the Ovi Store, however whenever I click on it it says the item is no longer available. First day nerves, I bet. [Nokia Conversations]
Perry’s win a huge victory for the Hard Right
Rick Perry's win on a strong anti-Washington message is being seen as a big victory for limited government conservatism.
From Jonathan Martin at Politico:
Texas GOP Gov. Rick Perry has embraced the cause of state sovereignty, suggested his famously independent state could secede from the union, deemed the president a socialist and, last month in Houston, happily stood by former Alaska Gov. Sarah Palin’s side to receive her endorsement. Perry’s approach seems to be paying dividends...
Meanwhile, the liberal Huffington Post acknowledged, Perry's win, "highlighted the growing anti-Washington mood among voters in midterm elections."
And from the foreign press, the UK Guardian describes Perry's win as an absolute "shock" to American politics:
More moderate Republicans face being displaced by candidates backed by the Tea Party and other grassroots right-wingers... The right-wing, anti-Washington mood engulfing the US last night claimed another victim when the Republican senator Kay Bailey Hutchison was forced out of the race to become governor of Texas.
The latest upset comes only two months after grassroots activists from round the country contributed to the shock Republican victory in the battle for Ted Kennedy’s Senate place.
The result suggests a shift to the right lies ahead in the Republican party both in Congress and among governors.
Moderate Republicans face being displaced by more right-wing candidates, backed by Tea Party activists and others who complain the Republican party has betrayed its core principles. These right-wingers oppose federal government spending under Barack Obama, the proposed health care bill and immigration reform, and blame Republicans for failing to oppose the spending.
The Guardian ominously warns that Charlie Crist in Florida and even moderately conservative John McCain, could next face the wave of libertarian-conservative angst.
Rick Perry Wins! Now it’s on to fighting Obama and Washington
Stop Messin' with Texas
Governor Rick Perry graciously thanked his opponent Kay Baily-Hutchison first off in his victory speech delivered from a Texas-style BBQ & Cookoff in Driftwood late last night. But he failed to mention his Democrat rival, former Houston Mayor Bill White. Instead he made it clear, his main opponent is Obama, along with Washington liberals who want to tell Texans how to run their state.
From the Dallas Morning News:
"It is clear that the Obama administration and its allies already have Texas in their cross hairs," Perry said. People in the crowd shouted, "Bring it on!"
The governor continued, "I can probably assure you that we're going to get all kinds of special attention in the future. But until Washington gets its priorities into order, and it retreats to the proper boundaries that are detailed in the 10th Amendment, we're going to move forward in this state to sustain the economy here in Texas."
"Texas voters, they said no to Washington bureaucrats making decisions that state leaders and citizens should be making themselves," he said. "They said no to a culture of reckless spending policies that endanger our children's future." And he castigated federal legislation on carbon emissions and health care as job killers in Texas.
"Stop messing with Texas," he said. "That message resonates. It resonates across our state."
The final vote: Rick Perry 51%, Kay B. Hutchison 28.8%.
