As seen on the National Geographic Channel's Live from Space: exercise in space! Train live an astronaut. Flight Engineer Karen Nyberg poses for a photo while exercising on the Cycle Ergometer with Vibration Isolation System in the Destiny laboratory of the International Space Station. Exercising and eating well keeps bones and muscles strong even in long term missions in microgravity. #iss #livefromspace #spacestation #space #nasa #exploration; -

Happy Pi Day! Our Cassini spacecraft uses "pi transfer" to navigate path around Saturn. On Jan. 19, 2007, the Cassini spacecraft took this view of Saturn and its rings -- the visible documentation of a technique called a "pi transfer" completed with a Titan flyby. A pi transfer uses the gravity of Saturn's largest moon, Titan, to alter the orbit of the Cassini spacecraft so it can gain different perspectives on Saturn and achieve a wide variety of science objectives. During a pi transfer, Cassini flies by Titan at opposite sides of its orbit about Saturn (i.e., Titan's orbital position differs by pi radians between the two flybys) and uses Titan's gravity to change its orbital perspective on the ringed planet.

An Interstellar Butterfly! The "butterfly effect" says the flap of a butterfly's wings may lead to a developing hurricane on the other side of the world. But what happens when a butterfly flaps its wings in the depths of space? This cosmic butterfly is a nebula known as AFGL 4104, or Roberts 22. Caused by a star that is nearing the end of its life and has shrugged off its outer layers, the nebula emerges as a cosmic chrysalis to produce this striking sight. Studies of the lobes of Roberts 22 have shown an amazingly complex structure, with countless intersecting loops and filaments. A butterfly's life span is counted in weeks; although on a much longer timescale, this stage of life for Roberts 22 is also transient. It is currently a pre-planetary nebula, a short-lived phase that begins once a dying star has pushed much of the material in its outer layers into space, and ends once this stellar remnant becomes hot enough to ionize the surrounding gas clouds and make them glow. About 400 years ago, the star at the center of Roberts 22 shed its outer shells, which raced outwards to form this butterfly. The central star will soon be hot enough to ionize the surrounding gas, and it will evolve into a fully-fledged planetary nebula.

Solar flare! The sun emitted a mid-level solar flare, peaking at 6:34 p.m. EDT on March 12, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured an image of it. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. SDO captures images of the sun in many wavelengths of light at the same time, each of which is typically colorized in a different color. Each wavelength shows different aspects of the same event, as seen in these two images of the solar flare.

Space Communications Antenna Supported Early NASA Missions - This 26 meter (85 foot) antenna operated in Woomera (Island Lagoon), Australia at Deep Space Station (DSS) 41, established in August 1960. The Island Lagoon site was the first deep space station to be established outside the United States and the first Australian antenna NASA built. The station was operated by the Australian Department of Supply and helped support the Ranger and early Mariner missions, as well as communications from the Deep Space Network (DSN) complex in Goldstone, California via a moon bounce. Woomera’s antenna ceased operations in 1972. Today, the Deep Space Network -- consisting of three sites in Goldstone, California; Madrid, Spain; and Canberra, Australia -- supports space communications for NASA and non-NASA missions that explore the furthest points of our solar system. Each complex currently has a 70 meter (230 foot) antenna, one 34 meter (111 foot) High Efficiency (HEF) antenna, and one or more 34 meter Beam Wave Guide (BWG) antenna. The Deep Space Network is operated 24 hours a day, seven days a week, 365 days per year. To support future mission needs, construction is currently underway in Canberra, Australia to add two new 34 meter BWG antennas, Deep Space Station 35 (DSS-35) and DSS-36 by 2018.

Boosters for Orion Spacecraft's First Flight Test Arrive at Port Canaveral, Florida - A barge arrives at the U.S. Army Outpost wharf at Port Canaveral in Florida, carrying two of the three United Launch Alliance Delta IV heavy boosters for NASA’s upcoming Exploration Flight Test-1 (EFT-1) with the Orion spacecraft. The core booster and starboard booster will be offloaded and then transported to the Horizontal Integration Facility, or HIF, at Space Launch Complex 37 on Cape Canaveral Air Force Station. The port booster and the upper stage are planned to be shipped to Cape Canaveral in April. At the HIF, all three boosters will be processed and checked out before being moved to the nearby launch pad and hoisted into position. Orion is the exploration spacecraft designed to carry astronauts to destinations in deep space, including an asteroid and Mars. Image Credit: NASA #nasa #space #orion #eft1 #exploration #spacecraft;

A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. This research hinges on a new and more detailed calculation of the sensitivity of Earth's climate to the factors that cause it to change, such as greenhouse gas emissions. Drew Shindell, a climatologist at NASA's Goddard Institute for Space Studies in New York, found Earth is likely to experience roughly 20 percent more warming than estimates that were largely based on surface temperature observations during the past 150 years. Global temperatures have increased at a rate of 0.22 Fahrenheit (0.12 Celsius) per decade since 1951. But since 1998, the rate of warming has been only 0.09 F (0.05 C) per decade -- even as atmospheric carbon dioxide continues to rise at a rate similar to previous decades. Carbon dioxide is the most significant greenhouse gas generated by humans. Some recent research, aimed at fine-tuning long-term warming projections by taking this slowdown into account, suggested Earth may be less sensitive to greenhouse gas increases than previously thought.

Expedition 38 Flight Engineer Mike Hopkins of NASA gives an OK sign as he is helped from the Soyuz Capsule just minutes after he and Commander Oleg Kotov of the Russian Federal Space Agency (Roscosmos), and, Flight Engineer Sergey Ryazanskiy of Roscosmos, landed in their Soyuz TMA-10M spacecraft near the town of Zhezkazgan, Kazakhstan on Tuesday, March 11, 2014. Hopkins, Kotov and Ryazanskiy returned to Earth after five and a half months onboard the International Space Station where they served as members of the Expedition 37 and 38 crews.
