Speed Of The Sun 'Shockingly' Slower Than Believed
2012-05-11 04:06:18

[ Watch the Video ] A team of NASA researchers has uncovered new data showing that the sun is moving more slowly through our galaxy than previously believed -- a discovery that suggests a shock wave believed to precede the heliosphere might not actually exist, the US space agency revealed on Thursday. According to Andrew Fazekas of National Geographic News, NASA's Interstellar Boundary Explorer (IBEX) satellite measured the speeds of various interstellar particles along the outer edges...

Alien Matter In The Solar System: A Galactic Mismatch
2012-02-12 05:14:50

[ Watch the Video ] This just in:  The Solar System is different from the space just outside it. Researchers announced the finding at a press conference on Jan. 31, 2012. It´s based on data from NASA´s IBEX spacecraft, which is able to sample material flowing into the solar system from interstellar space. “We´ve detected alien matter that came into our solar system from other parts of the galaxy--and, chemically speaking, it´s not exactly like what we...

Voyager Instrument Cooling After Heater Turned off
2012-01-18 12:59:22

In order to reduce power consumption, mission managers have turned off a heater on part of NASA's Voyager 1 spacecraft, dropping the temperature of its ultraviolet spectrometer instrument more than 23 degrees Celsius (41 degrees Fahrenheit). It is now operating at a temperature below minus 79 degrees Celsius (minus 110 degrees Fahrenheit), the coldest temperature that the instrument has ever endured. This heater shut-off is a step in the careful management of the diminishing electrical power...

NASA's Voyager Spacecraft Nears Edge Of The Solar System
2011-12-14 04:17:32

In 1977, Jimmy Carter was sworn in as president, Elvis died, Virginia park ranger Roy Sullivan was hit by lightning a record seventh time, and two NASA space probes destined to turn planetary science on its head launched from Cape Canaveral, Fla. The identical spacecraft, Voyager 1 and Voyager 2, were launched in the summer and programmed to pass by Jupiter and Saturn on different paths. Voyager 2 went on to visit Uranus and Neptune, completing the "Grand Tour of the Solar System," perhaps...

NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space. Data obtained from Voyager over the last year reveal this new region to be a kind of cosmic purgatory. In it, the wind of charged particles streaming out from our sun has calmed, our solar system's magnetic field has piled up, and higher-energy particles from inside our solar system appear to be leaking out into interstellar space. "Voyager tells us now that we're in a stagnation...

NASA´s New Horizons mission reached a special milestone Friday, Dec. 2, 2011, on its way to reconnoiter the Pluto system, coming closer to Pluto than any other spacecraft. It´s taken New Horizons 2,143 days of high-speed flight — covering more than a million kilometers per day for nearly six years–to break the closest-approach mark of 1.58 billion kilometers set by NASA´s Voyager 1 in January 1986. “What a cool milestone!” says New Horizons...

Voyager 2 Switches To Backup Thruster Set
2011-11-15 04:28:36

NASA's Voyager 2 has successfully switched to the backup set of thrusters that controls the roll of the spacecraft. Deep Space Network personnel sent commands to the spacecraft to make the change on Nov. 4 and received confirmation on Monday, November 14 that the switch has been made. The change allows engineers to reduce the amount of power that the 34-year-old spacecraft needs to operate by turning off the heater that keeps the fuel to the primary thrusters warm. Although the rate of...

Voyager 2 Set To Switch To Backup Thruster Set
2011-11-07 10:11:55

NASA's Deep Space Network personnel sent commands to the Voyager 2 spacecraft Nov. 4 to switch to the backup set of thrusters that controls the roll of the spacecraft. Confirmation was received today that the spacecraft accepted the commands. The change will allow the 34-year-old spacecraft to reduce the amount of power it requires to operate and use previously unused thrusters as it continues its journey toward interstellar space, beyond our solar system. Launched in 1977, Voyager 1 and...

Saturn's moon Pan -- Pan, the innermost known satellite, was found from photographs taken by Voyager during its encounter with Saturn. It was discovered by Mark R. Showalter in 1990, 9 years after the Voyager encounter. Pan is located 133,583 kilometers from the center of Saturn and is within the Encke Gap of Saturn's A-ring. It acts as a shepherd and is responsible for keeping the Encke gap open. It has a diameter of 20 kilometers. ----- Discovered by: Mark R. Showalter;...
