NASA Parker Solar Probe launch in historic lift off as 7-year mission begins.

The NASA Parker Solar Probe has blasted off from Florida’s Cape Canaveral air base in a seven-year mission to explore the Sun’s outer-atmosphere.
The car-sized spacecraft was successfully launched on board NASA’s Delta IV Heavy rocket at 8:31am UK time (3:31am EDT).

Rarely Used Heavyweight Atlas V Delivers Military AFSPC-11 Payload

Pummeling the ground with an estimated 2.5 million pounds (1.1 million kg) of thrust, the largest and most powerful member of United Launch Alliance’s (ULA) Atlas V fleet roared aloft earlier tonight (Saturday, 14 April), to deliver a multi-purpose payload into orbit on behalf of the U.S. Air Force Space Command. Liftoff of the Atlas V 551—equipped with a 17-foot-wide (5-meter) payload fairing, five strap-on solid-fueled rockets and a single-engine Centaur upper stage—occurred from Space Launch Complex (SLC)-41 at Cape Canaveral Air Force Station, Fla., at 7:13 p.m. EDT, right on the opening of tonight’s two-hour “window”...

NASA’s Juno Spacecraft in Orbit Around Mighty Jupiter

After an almost five-year journey to the solar system’s largest planet, NASA’s Juno spacecraft successfully entered Jupiter’s orbit during a 35-minute engine burn. Confirmation that the burn had completed was received on Earth at 8:53 p.m. PDT (11:53 p.m. EDT) Monday, July 4.

NASA’s Three-Billion-Mile Journey to Pluto Reaches Historic Encounter

NASA’s New Horizons spacecraft is at Pluto.

After a decade-long journey through our solar system, New Horizons made its closest approach to Pluto Tuesday, about 7,750 miles above the surface — roughly the same distance from New York to Mumbai, India – making it the first-ever space mission to explore a world so far from Earth.

“I’m delighted at this latest accomplishment by NASA, another first that demonstrates once again how the United States leads the world in space,” said John Holdren, assistant to the President for Science and Technology and director of the White House Office of Science and Technology Policy. “New Horizons is the latest in a long line of scientific accomplishments at NASA, including multiple missions orbiting and exploring the surface of Mars in advance of human visits still to come; the remarkable Kepler mission to identify Earth-like planets around stars other than our own; and the DSCOVR satellite that soon will be beaming back images of the whole Earth in near real-time from a vantage point a million miles away. As New Horizons completes its flyby of Pluto and continues deeper into the Kuiper Belt, NASA’s multifaceted journey of discovery continues.”

NASA Mars Spacecraft Ready for Orbit Insertion

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled Sept. 21 insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles. Flight Controllers at Lockheed Martin Space Systems in Littleton, Colorado, will be responsible for the health and safety of the spacecraft throughout the process. The spacecraft’s mission timeline will place the spacecraft in orbit at approximately 9:50 p.m. EDT. “So far, so good with the performance of the spacecraft and payloads on the cruise to Mars,” said David Mitchell, MAVEN project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The team, the flight system, and all ground assets are ready for Mars orbit insertion.”

NASA’s New Horizons Mission Continuing Voyager’s Legacy of Exploration

NASA’s Mission to Pluto was a two part televised science event at NASA headquarters on August 25 – the same date that the agency’s New Horizons spacecraft passed the orbit of Neptune on its way to Pluto and exactly 25 years after the Voyager spacecraft’s encounter with Neptune in 1989. During the first event, entitled NASA’s New Horizons Pluto Mission: Continuing Voyager’s Legacy of Exploration, NASA scientists and officials discussed the two missions.

NASA’s RXTE Satellite Decodes the Rhythm of an Unusual Black Hole

Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA’s Rossi X-ray Timing Explorer (RXTE) satellite.

The signals have helped astronomers identify an unusual midsize black hole called M82 X-1, which is the brightest X-ray source in a galaxy known as Messier 82. Most black holes formed by dying stars are modestly-sized, measuring up to around 25 times the mass of our sun. And most large galaxies harbor monster, or supermassive, black holes that contain tens of thousands of times more mass.

“Between the two extremes of stellar and supermassive black holes, it’s a real desert, with only about half a dozen objects whose inferred masses place them in the middle ground,” said Tod Strohmayer, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

NASA’s MAVEN Mars orbiter set to launch on Nov. 18

Ken Kremer www.kenkremer.com for  space-site.com – 15 Oct  2013

KENNEDY SPACE CENTER, FL, USA – MAVEN (Mars Atmosphere and Volatile EvolutioN Mission) is NASA’s next mission to Mars.   It is scheduled to lift off on Nov. 18, 2013 from Cape Canaveral, Florida on an Atlas V 401 rocket.  The 903 kilogram (2000 pound) probe will arrive at the Red Planet in September 2014 after a 10 month interplanetary voyage.

It is the first spacecraft from Earth devoted to investigating and understanding the upper atmosphere of Mars. The purpose is determining how and why Mars lost virtually all of its atmosphere billions of years ago and what effect that had on the climate.

“MAVENS’s goal is determining the composition of the ancient Martian atmosphere and when it was lost, where did all the water ...

GOCE completes mission

GOCE in orbit

After nearly tripling its planned lifetime, the Gravity field and steady-state Ocean Circulation Explorer – GOCE – is nearing its end of mission and will soon reenter our atmosphere.

With a sleek, aerodynamic design responsible for it being dubbed the ‘Ferrari of space’, GOCE has mapped variations in Earth’s gravity with extreme detail. Scientists further exploited these data to create the first global high-resolution map of the boundary between Earth’s crust and mantle – called the Moho – and to detect sound waves from the massive earthquake that hit Japan on 11 March 2011, among other results.

In mid-October, the mission will come to a natural end when it runs out of fuel and the satellite begins its descent towards Earth from a height of about 224 km.

ESA and NASA stumped by cosmic mystery

Malargüe station today

A mystery that has stumped scientists for decades might be one step closer to solution after ESA tracking stations carefully record signals from NASA’s Juno spacecraft as it swings by Earth today.

NASA’s deep-space probe will zip past to within 561 km at 19:21 GMT as it picks up a gravitational speed boost to help it reach Jupiter in 2016.

During the high-speed event, radio signals from the 3225 kg Juno will be carefully recorded by ESA tracking stations in Argentina and Australia.

Engineers hope that the new measurements will unravel the decades-old ‘flyby anomaly’ – an unexplained variation in spacecraft speeds detected during some swingbys.

“We detected the flyby anomaly during Rosetta’s first Earth visit in March 2005,” says Trevor Morley, flight dynamics expert at ESA’s ESOC...
