NASA Celebrates 40th Anniversary Of Pioneer 11
2013-04-05 14:51:40

[ Watch the Video: Pioneer 11 Animation and Archive Footage ] Michael Harper for redOrbit.com — Your Universe Online NASA is celebrating the 40th birthday of the Pioneer 11 spacecraft. For the past four decades, Pioneer has been hurtling through space, capturing satellite images of the planets Jupiter and Saturn. As its predecessor, Pioneer 10 had launched just over a year before and was the first spacecraft to not only leave the inner Solar System, but make the trip to Jupiter as...

NASA Renames Radiation Belt Mission
2012-11-10 09:36:40

April Flowers for redOrbit.com — Your Universe Online NASA announced the renaming of a recently launched mission to study the radiation belts to the Van Allen Probes in honor of the late James Van Allen, head of the physics department at the University of Iowa. Van Allen discovered the radiation belts encircling Earth in 1958. NASA announced the new name, previously the Radiation Belt Storm Probes (RBSP), at a ceremony at the Johns Hopkins University Applied Physics Laboratory...

Pioneer Anomaly: What Is It?
2012-07-18 14:25:52

Lee Rannals for redOrbit.com - Your Universe Online NASA's Pioneer 10 and 11 spacecraft have apparently slowed down due to heat pushing back on the spacecraft, according to new findings. The effect, known as "Pioneer Anomaly," takes place when heat emanates from electrical current flowing through instruments and the thermoelectric power supply. "The effect is something like when you're driving a car and the photons from your headlights are pushing you backward," Slava Turyshev, lead...

NASA's Voyager Spacecraft Nears Edge Of The Solar System

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...

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...

WASHINGTON, June 9, 2011 /PRNewswire-USNewswire/ -- Observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles approximately 100 million miles wide. The bubbles are...

Ed Stone, project scientist for NASA's Voyager mission, remembers the first time he saw the kinks in one of Saturn's narrowest rings. It was the day the Voyager 1 spacecraft made its closest approach to the giant ringed planet, 30 years ago. Scientists were gathering in front of television monitors and in one another's offices every day during this heady period to pore over the bewildering images and other data streaming down to NASA's Jet Propulsion Laboratory in Pasadena, Calif. Stone drew...

A University of Colorado at Boulder space dust counter designed, tested and operated by students that is flying aboard NASA's New Horizons mission to Pluto now holds the record for the most distant working dust detector ever to travel through space. The instrument on the New Horizons mission -- officially named the Venetia Burney Student Dust Counter, or SDC, after an 11-year-old English girl who named Pluto more than 75 years ago -- reached a distance of 1.67 billion miles from Earth on Oct....

The Pioneer Program is a series of American unmanned space missions designed for planetary exploration. The program included a number of missions, but the most well-known missions were Pioneer 10 and Pioneer 11. Both Pioneer 10 and 11 explored the outer planets and left our solar system. Both probes carry a gold plaque, depicting a man and a woman and information about the origin of the probes and their creators. The Pioneer probe was named by Stephen A. Saliga, who was chief designer of Air...

The Planet Saturn -- in astronomy, 6th planet from the sun. Astronomical and Physical Characteristics of Saturn Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years. Saturn appears in the sky as a yellow, starlike object of the first magnitude. When viewed through a telescope, it is seen as a golden sphere, crossed by a series of...
