Scientific Balloon Team Hopes to Break Flight Duration Record with New Zealand Launch! After years of tests and development, NASA's Balloon Program team is on the cusp of expanding the envelope in high-altitude, heavy-lift ballooning with its super pressure balloon (SPB) technology. Our scientific balloon experts are in Wanaka, New Zealand, prepping for the fourth flight of an 18.8 million-cubic-foot (532,000 cubic-meter) balloon, with the ambitious goal of achieving an ultra-long-duration flight of up to 100 days at mid-latitudes. Launch of the pumpkin-shaped, football stadium-size balloon is scheduled for some time after April 1, 2016, from Wanaka Airport, pending final checkouts and flight readiness of the balloon and supporting systems.

The Crab Pulsar is the end result of a star whose mass collapsed at the end of its life. It weighs as much as our sun, but spins 32 times per second. An instrument on the Hale telescope at the Palomar Observatoryfocused on the pulsar for a 300-second exposure to produce a color image. CHIMERA zoomed in on the pulsar and imaged it very fast, then imaged the rest of the scene slowly to create this image. Credits: NASA/JPL-Caltech #nasa #space #astronomy #nasabeyond #science; -
Home Sweet Home: Back on Earth after a spending a #YearInSpace, NASA astronaut Scott Kelly rests in a chair outside of the spacecraft just minutes after he and Russian cosmonauts Mikhail Kornienko and Sergey Volkov of Roscosmos landed in a remote area in Kazakhstan Tuesday at 11:25 p.m EST (10:26 a.m. March 2 Kazakhstan time). Kelly and Kornienko completed an International Space Station record year-long mission to collect valuable data on the effect of long duration weightlessness on the human body that will be used to formulate a human mission to Mars. Volkov returned after spending six months on the station. Photo Credit: (NASA/Bill Ingalls) #nasa #space #science #iss #spacestation #astronauts; -
Today is the day! Astronaut Scott Kelly (@StationCDRKelly) returns to Earth from his #YearInSpace mission aboard the space station (@ISS). He posted this image and wrote, "#Earth. I'm coming for you." Kelly launched to the space station March 27, 2015, from the Baikonur Cosmodrome in Kazakhstan and is set to land in Kazakhstan at 11:27 p.m. EST with his one-year crewmate, cosmonaut Mikhail Kornienko of the Russian space agency Roscosmos, and cosmonaut Sergey Volkov, also of Roscosmos. Kelly will return to Houston's Ellington Field on Wednesday, March 2. After landing, Kelly will hold the record among U.S. astronauts for cumulative time in space, with 520 days. During their record-setting mission, Kelly and Kornienko participated in a number of studies to provide new insights into how the human body adjusts to weightlessness, isolation, radiation and the stress of long-duration spaceflight, which will include the #JourneytoMars.

It's #Oscars night and while #TheMartian is up for awards, we're going to explore the Red Planet. Seen here is Mars with the Valles Marineris showing. It's the largest canyon in the Solar System and it cuts a wide swath across the face of Mars. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris remains unknown, although a leading hypothesis holds that it started as a crack billions of years ago as the planet cooled. Recently, several geologic processes have been identified in the canyon. The above mosaic was created from over 100 images of Mars taken by Viking Orbiters in the 1970s.

Eclipse Season: Due to the geometry of our Solar Dynamic Observatory's orbit, there are periods when the spacecraft's view of the sun is blocked by the Earth and sometimes the moon. Starting this earlier this week (video taken on Feb. 22) and for the next few weeks, the Earth will continue to get in the way once a day around 7:00 UT. This eclipse season occurs twice a year, near the equinoxes. The sun was blocked for close to an hour. Such is life in space 22,000 miles above Earth.

Blue Bubble: Sparkling at the center of this beautiful Hubble Space Telescope image is a Wolf-Rayet star known as WR 31a, located about 30,000 light-years away. The distinctive blue bubble appearing to encircle WR 31a is a Wolf-Rayet nebula - an interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with the outer layers of hydrogen ejected by Wolf-Rayet stars, these nebulae are frequently ring-shaped or spherical. The bubble - estimated to have formed around 20,000 years ago - is expanding at a rate of around 220,000 kilometers (136,700 miles) per hour! Unfortunately, the lifecycle of a Wolf-Rayet star is only a few hundred thousand years - the blink of an eye in cosmic terms.

Frozen Canyons of Pluto's North Pole: This ethereal scene captured by our New Horizons spacecraft tells yet another story of Pluto's diversity of geological and compositional features-this time in an enhanced color image of the north polar area. Long canyons run vertically across the polar area. The widest of the canyons is about 45 miles (75 kilometers) wide and runs close to the north pole. The degraded walls of these canyons appear to be much older than the more sharply defined canyon systems elsewhere on Pluto, perhaps because the polar canyons are older and made of weaker material. These canyons also appear to represent evidence for an ancient period of tectonics. Credits: NASA/JHUAPL/SwRI #nasa #space #pluto #plutoflyby #solarsystem #astronomy #nasabeyond #geology #science; -
Flying Through the Aurora's Green Fog: Astronaut Tim Peake (@astro_timpeake) of the European Space Agency (ESA) shared a stunning image of a glowing aurora taken on Feb. 23 from the International Space Station. Peake wrote, "The @ISS just passed straight through a thick green fog of #aurora...eerie but very beautiful. #Principia" The dancing lights of the aurora provide spectacular views on the ground, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections or CMEs.

The Ice Fields of Patagonia: This image shows the glaciers of Sierra de Sangra, an icy stratovolcano spanning the border of Chile and Argentina. Snow and ice are blue in these false-color images, which use different wavelengths to better differentiate areas of ice, rock, and vegetation. Since the end of the Little Ice Age, the ice fields of Patagonia and other parts of South America have been shrinking as global temperatures have increased. A number of studies have investigated these changes, which can affect the communities downstream that rely on the glaciers for a steady water supply.

"A sky full of #stars and Earth aglow below," wrote NASA astronaut Scott Kelly (@StationCDRKelly) when posting this image. Astronauts aboard the International Space Station (@ISS) capture photographs and video of the routinely. Kelly shared this stunning image on Thursday, Feb, 11. The station is a unique place - a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. It is a microgravity laboratory in which an international crew of six people live and work while traveling at a speed of 17,500 mph, orbiting Earth every 90 minutes.

Diamond in the Dust: Surrounded by an envelope of dust, the subject of this Hubble Space Telescope image is a young forming star known as HBC 1. The star is in an immature and adolescent phase of life, while most of a sun-like star's life is spent in a stable stage comparable to human adulthood. In this view, HBC 1 illuminates a wispy reflection nebula. Formed from clouds of interstellar dust, reflection nebulae do not emit any visible light of their own. Instead, like fog encompassing a lamppost, they shine via the light reflected off the dust from the stars embedded within. Though nearby stars cannot ionize the nebula's dust, as they can for gas within brighter emission nebulae, scattered starlight can make the dust visible in a reflection nebula.

Our Mars orbiter sees the western side of an elongated pit depression in the eastern Noctis Labyrinthus region of Mars. Along the pit's upper wall is a light-toned layered deposit. Noctis Labyrinthus is a huge region of tectonically controlled valleys located at the western end of the Valles Marineris canyon system. Spectra extracted from the light-toned deposit are consistent with the mineral jarosite, which is a potassium and iron hydrous sulfate. On Earth, jarosite can form in ore deposits or from alteration near volcanic vents, and indicates an oxidizing and acidic environment.
