NASA says it could be another 20 years before humans touch down on Mars, but in a sense, the Mars Society has been exploring the red planet for more than a decade – in Utah. Photo: Csilla Orgel, a geologist of Crew 125 EuroMoonMars B mission, makes her way back to the Mars Desert Research Station (MDRS) in the Utah desert March 3, 2013. The MDRS aims to investigate the feasibility of a human exploration of Mars and uses the Utah desert's Mars-like terrain to simulate working conditions on the red planet. Scientists, students and enthusiasts work together developing field tactics and studying the terrain. All outdoor exploration is done wearing simulated spacesuits and carrying air supply packs and crews live together in a small communication base with limited amounts of electricity, food, oxygen and water. Everything needed to survive must be produced, fixed and replaced on site. (Photo by Jim Urquhart/Reuters)

Gers, traditional Mongolian tents, are seen on a hill in an area known as a ger district in Ulan Bator June 26, 2013. Approximately 60 percent of the population of Ulan Bator live in settlements known as ger districts and in many cases residents have limited access to basic services such as water and sanitation. According to a 2010 National Population Center census, every year between thirty and forty thousand people migrate from the countryside to the capital Ulan Bator. Ger districts in the city have been expanding rapidly in recent years. Mongolia is the world's least densely populated country, with 2.8 million people spread across an area around three times the size of France. (Photo by Carlos Barria/Reuters)

“Inspired by the French authorities' solution to move Romas from point A to point B, Romanian authorities planned and started forced evictions of Roma informal settlements in cities like Cluj-Napoca and Baia Mare. Some of these settlements date back to the early 1990’s. These communities were tolerated by the authorities who verbally encouraged Romas to build in the area, meanwhile, reassuring them nothing bad would ever happen to them. However, the the reality today is that during political campaigns, authorities are planning forced evictions without reasons other than ethnic cleansing of the cities. My home documents the every day life of Roma communities in Romania, 2011”. – Mugur Varzariu. (Photo by Mugur Varzariu, 2011 FotoVisura Grant Finalist)

Kyaiktiyo Pagoda, also known as Golden Rock is a well-known Buddhist pilgrimage site in Mon State, Burma. It is a small pagoda (7.3 metres (24 ft)) built on the top of a granite boulder covered with gold leaves pasted on by devotees. According to legend, the Golden Rock itself is precariously perched on a strand of the Buddha's hair. The balancing rock seems to defy gravity, as it perpetually appears to be on the verge of rolling down the hill. The rock and the pagoda are at the top of Mt. Kyaiktiyo. It is the third most important Buddhist pilgrimage site in Burma after the Shwedagon Pagoda and the Mahamuni Pagoda. A glimpse of the "gravity defying" Golden Rock is believed to be enough of an inspiration for any person to turn to Buddhism.

A rat being trained by the Cambodian Mine Action Centre (CMAC) is pictured on an inactive landmine field in Siem Reap province July 9, 2015. Gambian pouched rats were deployed to Cambodia from Tanzania in April by a Belgian non-profit organization, APOPO, to help clear mines. They've been trained since they were 4 weeks old. Cambodia is still littered with landmines after emerging from decades of civil war, including the 1970s Khmer Rough “Killing Fields” genocide, leaving it with one of the world's highest disability rates. APOPO has used the rodents for mine-clearing projects in several countries, including Angola, Mozambique, Thailand, Laos, and Vietnam. (Photo by Samrang Pring/Reuters)
