Yves “Jetman”, Rossy made his first public performance in the United States on Tuesday during the afternoon air show at EAA AirVenture. As thousands of spectators leaned back and clicked cameras, Rossy jumped out of a helicopter with his 6-foot carbon fiber wing armed with four 45-pound-thrust JetCat engines strapped to his back.

“The Space Launch System, or SLS, is a Shuttle-Derived heavy launch vehicle being designed by NASA, following the cancellation of the Constellation Program, to replace the Space Shuttle after its retirement. The NASA Authorization Act of 2010 envisions the transformation of the Ares I and Ares V vehicle designs into a single launch vehicle usable for both crew and cargo. It is to be upgraded over time with more powerful versions. The proposed SLS is visually similar to the legacy Saturn V booster and in particular the proposed, two-stage, Saturn INT-20”. – Wikipedia

NASA's new rocket design will reportedly cost about $35 billion and be ready to for test launch in 2017. According to NASA, the rocket will be used to carry Orion Multi-Purpose Crew Vehicle as well as cargo and science experiments to earth's orbit, as a backup for the space station and possibly destinations beyond that.

The aurora borealis, also known as the northern lights, visible above Old Gardur Lighthouse on the northern point of the Reykjanes peninsula in Iceland on Sunday, November 24, 2024. The lighthouse dates to 1897, and was one of the first built in Iceland. (Photo by Owen Humphreys/PA Images via Getty Images)

These are the spectacular snaps of swirling star trails which transform the night sky into a kaleidoscope of color. Keen photographer Evgeniy Zaytsev, 24, captured the stunning shots on trips to Crimea, Altai and Murom, Russia. The pictures of circular star trails are formed by merging multiple photos taken over the course of several hours. Movement of the Earth causes the stars appear in different places in each image. Here: vibrate, colorful star trails over an abandoned beach house. (Photo by Evgeniy Zaytsev/Caters News)

An image produced by the Hubble telescope of the perfectly “edge-on” galaxy, or NGC 4013, March 1, 2001. This new Hubble picture reveals, with great detail, huge clouds of dust and gas extending along, as well as far above, the galaxy's main disk. NGC 4013 is a spiral galaxy, similar to the Milky Way, lying some 55 million light-years from Earth in the direction of the constellation Ursa Major. Viewed face-on, it would look like a nearly circular pinwheel, but NGC 4013 happens to be seen edge-on from our vantage point. Even at 55 million light-years, the galaxy is larger than Hubble's field of view, and the image shows only a little more than half of the object, albeit with unprecedented detail.

“Solar Impulse is a European long-range solar powered plane project being undertaken by Bertrand Piccard and André Borschberg. The project eventually hopes to succeed in the first circling of the earth with a piloted fixed-wing aircraft using only solar power. The first aircraft, bearing the Swiss aircraft registration code of HB-SIA, is a single-seater, capable of taking off under its own power, and intended to remain airborne up to 36 hours. This aircraft first flew an entire diurnal solar cycle, including nearly 9 hours of night flying, in a 26-hour flight on 7–8 July 2010”. – Wikipedia

Solar Impulse chairman Bertrand Piccard, psychatrist and aeronaut, who made the first non-stop round-the-world balloon flight, and CEO and former fighter pilot Andrй Borschberg plan a round-the-world flight, driven only by solar energy, for 2012.

The fourth annual BigPicture Natural World Photography Competition aims to celebrate the diversity of life on Earth, and encourages people to protect and conserve it. Here: “The Salmon Catchers”. Terrestrial Wildlife. To capture this view of a mother grizzly bear and her cub, photographer Peter Mather set up a camera trap on a log that he knew the bears tended to traverse while fishing for salmon, in the Yukon River watershed in Canada.
