Today’s launch attempt of the Orbiting Carbon Observatory-2 was scrubbed because of a failure in a Vandenberg Air Force Base Space Launch Complex 2 pad water system. The system provides sound suppression to dampen acoustic waves at liftoff and protects a launch pad flame duct. The #OCO2 spacecraft is on external power and the #DeltaII rocket first stage liquid oxygen is being offloaded. Both the spacecraft and rocket are in a safe configuration. Managers and engineers are assessing the issue to determine the cause of the failure and when they next can reschedule the launch. The United Launch Alliance Delta II rocket with the Orbiting Carbon Observatory-2 (OCO-2) satellite onboard, is seen at the Space Launch Complex 2, Monday, June 30, 2014, Vandenberg Air Force Base, Calif.

NASA’s Orbiting Carbon Observatory-2 (OCO-2) spacecraft is poised for launch at Vandenberg Air Force Base Space Launch Complex 2 in California. OCO-2 will be delivered to space by a United Launch Alliance Delta II rocket. Liquid oxygen has been fully loaded into the Delta II first stage, completing the fueling process. At liftoff, the Delta will stand about 127 feet tall and weigh approximately 165.5 tons. The first stage uses an Aerojet Rocketdyne RS-27A main engine burning RP-1 fuel, a rocket-grade kerosene, and liquid oxygen for the first 64 seconds of flight. The total thrust is about 237,000 pounds. Three solid rocket motors will add another 109,000 pounds of thrust each. The Delta II second stage features a restartable Aerojet Rocketdyne AJ10 engine burning Aerozine 50, which is a mixture of hydrazine and dimethyl hydrazine reacting with nitrogen tetroxide to produce 9,750 pounds of thrust. There are no technical issues with either OCO-2 or the Delta II and weather remains green. Liftoff is scheduled for the opening of a 30-second launch window at 5:56:44 a.m. EDT.

It has been a decade since a robotic traveler from Earth first soared over rings of ice and fired its engine to fall forever into the embrace of Saturn. Today the Cassini mission celebrates 10 years of exploring the planet, its rings and moons. The Cassini spacecraft, carrying the European Space Agency's Huygens probe, arrived in the Saturn system on June 30, 2004, for a four-year primary mission. Since 2008, NASA has granted the mission three extensions, allowing scientists an unprecedented opportunity to observe seasonal changes as the planet and its retinue completed one-third of their nearly 30-year-long trek around the sun. After 10 years at Saturn, the stalwart spacecraft has beamed back to Earth hundreds of gigabytes of scientific data, enabling the publication of more than 3,000 scientific reports. While Cassini was originally approved for a four-year study of the Saturn system, the project's engineers and scientists had high hopes that the mission might carry on longer, and designed the system for endurance. The spacecraft has been remarkably trouble-free, and from an engineering standpoint, the main limiting factor for Cassini's lifetime now is how much propellant is left in its tanks. The mission owes a great deal of its longevity to skillful and efficient piloting by the mission's navigation and operations teams.

First LDSD Test Flight a Success A high-altitude balloon launch occurred at 8:45 a.m. HST (11:45 a.m. PDT/2:45 p.m. EDT) on June 28, 2014 with the near-space test flight of the agency's Low-Density Supersonic Decelerator (LDSD). At 11:05 a.m. HST (2:05 p.m. PDT/5:05 p.m. EDT), the LDSD test vehicle dropped away from the balloon as planned and began powered flight. The balloon and test vehicle were about 120,000 feet over the Pacific Ocean at the time of the drop. The vehicle splashed down in the ocean at approximately 11:35 a.m. HST (2:35 p.m. PDT/5:35 p.m. EDT), after the engineering test flight concluded. The test vehicle hardware, black box data recorder and parachute were all recovered later in the day. This test was the first of three planned for the LDSD project, developed to evaluate new landing technologies for future Mars missions. While this initial test was designed to determine the flying ability of the vehicle, it also deployed two new landing technologies as a bonus. Those landing technologies will be officially tested in the next two flights, involving clones of the saucer-shaped vehicle. Seen here is the saucer-shaped test vehicle being lifted aboard the Kahana recovery vessel, hours after the June 28, 2014 test of NASA's Low-Density Supersonic Decelerator over the U.S. Navy's Pacific Missile Range.

This bright spiral galaxy is known as NGC 2441, located in the northern constellation of Camelopardalis (The Giraffe). However, NGC 2441 is not the only subject of this new Hubble image; the galaxy contains an intriguing supernova named SN1995E, visible as a small dot at the approximate centre of this image. Supernova SN1995E, discovered in 1995 as its name suggests, is a type Ia supernova. This kind of supernova is found in binary systems, where one star — a white dwarf — drags matter from its orbiting companion until it becomes unstable and explodes violently. White dwarf stars all become unbalanced once they reach the same mass, meaning that they all form supernovae with the same intrinsic brightness. Because of this, they are used as standard candles to measure distances in the Universe. But SN1995E may be useful in another way. More recent observations of this supernova have suggested that it may display a phenomenon known as a light echo, where light is scattered and deflected by dust along our line of sight, making it appear to “echo” outwards from the source. In 2006, Hubble observed SN1995E to be fading in a way that suggested its light was being scattered by a surrounding spherical shell of dust. These echoes can be used to probe both the environments around cosmic objects like supernovae, and the characteristics of their progenitor stars. If SN1995E does indeed have a light echo, it would belong to a very elite club; only two other type Ia supernovae have been found to display light echoes (SN1991T and SN1998bu).

Puff the Magic Sun: A suite of our sun-gazing spacecraft have spotted an unusual series of eruptions in which a series of fast puffs forced the slow ejection of a massive burst of solar material from the sun's atmosphere. The eruptions took place over a period of three days, starting on Jan. 17, 2013. This combination of three wavelengths of light from our Solar Dynamics Observatory shows one of the multiple jets that led to a series of slow coronal puffs. The light has been colorized in red, green and blue. Image Credit: Alzate/SDO #nasa #sun #space #solarsystem #science;

He actually did it! Yesterday's World Cup match of the U.S. vs Germany may just have been a friendly competition among U.S. and German astronauts on space station, but that didn't mean there weren't stakes involved. If the U.S. won, the America crew members was going to draw a little U.S. flag on Alexander Gerst's head. But Germany won, and now astronaut Reid Wiseman uphold his end of the bargain. Reid posted this image to Twitter and wrote, "Good game Germany! Thanks for the shave." Image Credit: NASA #nasa #worldcup #usavsgermany #usa #ger #iss #germany #usmnt; -
