This artist's scoreboard displays a fictional game between Mars and Earth, with Mars in the lead. It refers to the success rate of sending missions to Mars, both as orbiters and landers. Of the previous 39 missions targeted for Mars from around the world, 15 have been successes and 24 failures. For baseball fans, that's a batting average of .385. The United States has had 13 successes out of 18 attempts, or a “batting average” of .722. NASA's Curiosity rover, set to land on the Red Planet the evening of Aug. 5, 2012 PDT (morning of Aug. 6 EDT), will mark the United States' 19th attempt to tackle the challenge of Mars, and the world's 40th attempt.

Labourers pour molten iron into a container at a foundry in Xiangfan, Hubei province in this July 2, 2010 file photo. Iron ore is enjoying its biggest rally in years, outpacing copper and oil so far in 2016, but still weak forward prices show it may be tough to stretch the bullish outlook. Improving steel prices in top market China are helping fuel iron ore's climb as producers gear up for a seasonal uptick in demand. Yet there is no shortage of doubters who see gains in the bulk commodity as fleeting given a large glut and challenges for China's economy. (Photo by Reuters/Stringer)

Negin Ekhpulwak, leader of the Zohra orchestra, an ensemble of 35 women, practises on a piano at Afghanistan's National Institute of Music, in Kabul, Afghanistan April 9, 2016. Playing instruments was banned under Taliban rule in Afghanistan, and even today, many conservative Muslims frown on most forms of music. Living in an orphanage in the capital, Kabul, 19-year-old Negin Ikhpolwak leads an ensemble of 35 women that plays both Western and Afghan musical instruments. In a country notorious internationally for harsh restrictions on women in most areas of life, Negin's story highlights a double challenge. (Photo by Ahmad Masood/Reuters)

These ink-redible, explosive masterpieces are like say-what-you see inkblots tests only in water. The vibrant colors burst from Brian Tomlinsons works, appearing as though they may be coloured ash clouds from an erupting volcano, rather than simply everyday substances. By doing so, Brian challenges viewers to identify what images can be imagined when mixing one fluid with another. In order to shoot the series, entitled Liquid Ink Art, Brain, 40, drops different coloured inks into a fish tank full of water before capturing high-speed shots with a flash. Here: Brian Tomlinsons ink artwork. (Photo by Brian Tomlinsons/Caters News Agency)

A worker sweeps leaves below a historic spirit still at Suntory Holdings' Yamazaki Distillery in Shimamoto town, Osaka prefecture, near Kyoto, December 1, 2014. Nestled at the foot of wooded hills near the ancient Japanese capital of Kyoto, the Yamazaki whisky distillery feels a long way from the northerly glens of Scotch's spiritual home. Despite its unlikely birthplace, last month Yamazaki's Single Malt Sherry Cask 2013 trumped more than a thousand challengers to be named the world's best whisky by leading critic Jim Murray in his Whisky Bible 2015.

“A monowheel is a one-wheeled single-track vehicle similar to a unicycle. However, instead of sitting above the wheel, the rider sits either within it or next to it. The wheel is a ring, usually driven by smaller wheels pressing against its inner rim. Most are single-passenger vehicles, though multi-passenger models have been built.

Pedal-powered monowheels were built in the late 19th century; most built in the 20th century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles. Today, monowheels are generally built and used for fun and entertainment purposes, though from the 1860s through to the 1930s, they were proposed for use as serious transportation”. – Wikipedia

A member of staff prepares herself a crisp sandwich in the Simply Crispy sandwich cafe in Belfast, northern Ireland January 12, 2015. The sandwich shop which opened on Monday is the world's first crisp sandwich cafe, local media reported. The idea of a crisp sandwich cafe started as a joke article on a website called Ulster Fry. The hilarious piece poked fun at recent ridiculous foody trends like the cereal café that opened in London last year. What was once a satirical joke has now become reality, after Belfast cafe owner Andrew McMenamin decided to make it happen. Customers will be able to choose their bread and crisps and add cheese or ham to their sandwich, which will be served with soup and chips. (Photo by Cathal McNaughton/Reuters)
