In Burma, Satellite Images Show Extent of Religious Violence

The scale of devastation wreaked by last month’s communal riots in central Burma has been revealed by new satellite images. The remains of hundreds of smoldering homes scar three once-thriving Muslim neighborhoods of Meikhtila, a town of 100,000 people around 500 km north of Rangoon. Human Rights Watch (HRW) claims 828 buildings were obliterated across some 24 hectares. Most shocking has been the leading role the Buddhist clergy played in the bloodshed, creating a tinderbox atmosphere across the country that shows little sign of dissipating.

The sectarian violence was sparked by a seemingly innocuous dispute at a Muslim-owned gold shop in Meikhtila on March 20, yet soon spread across the region with frightening intensity. Before long 43 people had been killed, at least five mosques torched and around 12,000 people had fled to ramshackle displacement camps outside the town. The government imposed a state of emergency and curfews in certain hard-hit areas, but the violence nevertheless swelled to 11 nearby townships where Muslim districts were plundered. Brad Adams, Asia director of HRW, has since lamented “the failure of the police to stop wanton killings and the burning of entire neighborhoods.”

Similar Buddhist-Muslim violence devastated western Burma’s Arakan State last year in clashes that saw some people 120,000 forced from their homes and more than 120 lives lost. The fighting was mainly targeted at the Rohingya, a distinct Muslim group not included in Burma’s official 135 state ethnicities and so branded illegal migrants from neighboring Bangladesh. The government was therefore quick to brand the Arakan crisis an “immigration issue,” although the clearly anti-Muslim character of the latest violence, which did not involve the Rohingya, has since heralded a reevaluation of earlier incidents. Sources in Meikhtila told TIME on Tuesday that the situation there remains tense; Muslims are terrified to go out after dark and are not able to visit the town’s market to trade or collect supplies.

An estimated 442 buildings destroyed or severely damaged in one neighborhood of Meikhtila.

The clashes have been most notable for the brand of militant Buddhism that appears to be gaining ground in Burma since the end of junta rule. Monks have unparalleled moral authority in traditional Burmese society. U Wirathu, an outspoken monk who was jailed in 2003 for stirring religious clashes in the northern city of Mandalay, has dubbed himself “the Burmese Bin Laden” in reference to his religious fervor, despite his hatred of all things Islamic. The 45-year-old posted an inflammatory speech online last week that warned “once these evil Muslims have control and authority over us they will not let us practice our religion” and accused Muslims of accumulating “money to get our young Buddhist women.”

Wirathu is a leading figure of an extremist Buddhist movement identified by the numerals ‘969’ — representing the 9 attributes of the Lord Buddha, 6 attributes of Buddhist teachings and 9 attributes of monks. Abu Tahay, President Union National for Development Party, a Rohingya Muslim political group, told TIME that 969 stickers are common on the front of houses and taxis around Rangoon. “This sticker is now the symbol of the racists,” he says. “Not only the President but [democracy icon] Daw Aung San Suu Kyi should come out and give a concrete statement about the multicultural nature of our country.”

Tensions in the former capital have been further heightened by a fire at an Islamic school that claimed the lives of 13 children in the early hours of Tuesday morning. Around 70 youngsters were sleeping in the two-storey building near the city center when a blaze broke out at around 2:40 am local time. While the official explanation is that the fire was caused by faulty wiring in a transformer on the second floor, witnesses told reporters at the scene than ten men turned up in car, dosed the building with petrol and threw in a burning torch. TIME could not independently verify either report.

Official figures indicate that Burma’s population is only 4 percent Muslim, although many argue this is implausibly low considering the bevy of mosques that characterize almost every urban area. Religious intolerance is certainly not unknown in the country, with a raft of discriminatory legislation and pogroms against Muslims and South Asian immigrants after xenophobic dictator Ne Win seized power though a coup in 1962. The current situation is clearly troubling for reformist President Thein Sein as he marks the second anniversary of taking office. The former general has warned that he will not hesitate to use tough measures to maintain calm, but this is clearly an unsettling prospect considering the half-century of brutal military rule that his administration is attempting to banish from memory.

Students Get Satellite Time: Inside the Mars Student Imaging Project

A project that puts middle and high school students in charge of an instrument on NASA's Mars Odyssey orbiter received a top prize from the journal Science today (Feb. 21).

The journal recognized the Mars Student Imaging Project, which allows young scientists to request time on the Thermal Emission Imaging System (THEMIS) instrument aboard the satellite after developing and proposing their own research. But the benefits go beyond learning about Mars.

"The underlying premise of what Mars Student Imaging is about is helping students to learn the process of science, the nature of science and how it works," Sheri Klug Boonstra, director of the Arizona State University Mars Education program in charge of the project, told SPACE.com.

"They're going to be able to apply that understanding in every other class they take."

Science announced today that the project is the recipient of its Prize for Inquiry-Based Instruction, which seeks to recognize programs that promote active learning, where students are engaged in collecting data through resources or experiments. [Gallery: Students Use NASA Satellite to Study Mars]

"We're very humbled by it," Boonstra said. "It's been a great honor."

A growing project

After Odyssey launched in 2001, THEMIS principal investigator Philip Christensen, also at Arizona State University, began to think about a novel and innovative way to utilize the instrument. Christensen, a major proponent of education, met with Boonstra to determine how the camera could be used to engage people in the learning process.

"We thought, as a kid, I would have loved to participate in this kind of exploration, but it just wasn't available," Boonstra said.

They pitched the concept of adding students to the Mars team to NASA, where officials "loved it," Boonstra said.

"It's a collaboration between working scientists and education," she added.

When the Mars Student Imaging Project (MSIP) started in 2002, around 500 students were helping to beta test it. Today, more than 5,000 students a year are involved. In the last decade, more than 35,000 students in 33 states have participated, ranging from fifth-graders to undergraduate college students.

"We expect it to grow even more," Boonstra said.

While classrooms make up most groups, Boonstra emphasized that the opportunity was open to all sorts of teams. Home-schoolers, museums and after-school groups have all participated in the project. MSIP offers online training, virtual office hours and recorded seminars to adult leaders who will guide students in the program.

Studying the red planet

Participants in the project start off with a basic introduction to Mars. They become familiar with the surface of the Red Planet, and study orbital images of it. The students then develop a research question that can be tested by THEMIS, and figure out where and how to collect the appropriate data.

After the ASU Mars Education Program, which manages MSIP, accepts a proposal, the students use the Java Mission-planning and Analysis for Remote Sensing (JMARS) tool to study the planet's surface. Comprised of data sets of the surface taken by other researchers, JMARS is used by professional scientists as well as the student groups to take a closer look at the features in the planned target region.

The next step is in the hands of NASA, which uses Odyssey to capture the requested image of the Martian surface and sends them to the students. The teams, ranging from eight to 200 students, analyze the data they receive, creating graphs and collecting additional data. Finally, the teams present their findings to Mars scientists at Arizona State, either in person or over the Internet.

Occasionally, the student discoveries make headlines. In 2010, a group of middle school students discovered a never-before-seen Martian cave.

"These are seventh-graders that made that kind of contribution, that kind of discovery," Boonstra said. "That's where the kids get that this is real."

Other students may go on to present their findings at professional conferences or in scientific journals.

"These kids are stepping it up to be able to stand toe-to-toe with real researchers in presenting their findings at real conferences," Boonstra said.

"The nature of science"

As students follow the same route that professional scientists follow, from making proposals to analyzing data to presentations, they learn how the scientific process works.

"The kids know this is not a canned project," Boonstra said. "We don't have the answers. They're the ones with the answers at the end."

That kind of authentic science resonates with them, she said. Teachers have reported students wanting to stay later, skipping recess and going the extra mile.

"This project really does capture the imagination of these kids because it's so outside of the classroom worksheets and the regular stuff that you find in the classroom," she said.

And while Martian science may not be a large part of the curriculum, the lessons learned from the program transfer readily across science classes. A growing understanding of planetary science directly relates to Earth's formation and features.

Even more importantly, the students realize that science isn't always cut-and-dry.

"It's not a linear process," Boonstra said. "It's much more inquisitive."

She said questions often lead to more questions, and random-seeming tangents can grow into a whole new project.

"The nature of science is the nature of science," she said. "It works that way no matter what you're studying."
