NASA Voyager Missions Get Breakthrough Award From Popular Mechanics
2012-10-09 06:41:38

Lawrence LeBlond for redOrbit.com - Your Universe Online Hurtling through space at more than 35,000 miles per hour, NASA´s Voyager 1 is on the verge of breaking the barrier between the known Solar System and Interstellar Space; and Voyager 2 is not far behind. So what better way to commemorate such an event than with a prestigious award. Representatives from NASA´s Jet Propulsion Laboratory in Pasadena, California, the team behind the Voyager missions, received a Breakthrough...

Voyager 1 Celebrates 35th Anniversary, About To Cross Threshold Into Interstellar Space
2012-09-05 09:57:27

[WATCH VIDEO] Lawrence LeBlond for redOrbit.com - Your Universe Online Celebrating its 35th anniversary in space today, NASA´s Voyager 1 spacecraft is about to cross the threshold of our solar system, to boldly go where no man, nor machine, has ever gone before. While it is difficult to pinpoint the exact moment when the American space company´s premier long distance journeyer will cross the boundary of the heliosphere, expert measurements have indicated that it is very close....

Lee Rannals for redOrbit.com - Your Universe Online Monday marked the 35 year anniversary of NASA's Voyager 2 spacecraft launching from Earth, and embarking on a venture to go where no spacecraft has gone before. The Voyager 2 spacecraft, and its twin Voyager 1, are still hurtling through space, on a path that is sending them outside of our Solar System. "Even 35 years on, our rugged Voyager spacecraft are poised to make new discoveries as we eagerly await the signs that we've...

New Program Aims To Advance Scientific Understand Of Sun and Space Weather
2012-08-16 06:47:12

April Flowers for redOrbit.com - Your Universe Online A new report from the National Research Council lays out four scientific goals for the next 10 years along with guiding principles and recommended actions. The prioritized program of basic and applied research for 2012-2022 is meant to advance scientific understanding of the sun, sun-Earth connections, the origins of space weather, and the sun's interactions with other bodies in the solar system. This second decadal survey is the...

Voyager 1 Entering Interstellar Space
2012-06-15 13:52:45

Lee Rannals for redOrbit.com After several decades of making a lonely journey across our solar system, Voyager 1 has signaled to NASA that it may have reached the edge of interstellar space. The spacecraft, which launched in 1977, is now roughly 11 billion miles away and traveling at 6 miles per second. NASA said it takes Voyager 1's data 16 hours and 38 minutes to reach the antennas of its Deep Space Network on Earth. Data from the spacecraft indicates that the 34-year-old...

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...

ESA Contracts Astrium UK To Build Solar Orbiter
2012-04-27 03:18:20

ESA has awarded the contract to build its next-generation Sun explorer to Astrium UK. Solar Orbiter will investigate how the Sun creates and controls the heliosphere, the extended atmosphere of the Sun. Prof. Alvaro Giménez Cañete, ESA Director of Science and Robotic Exploration and Miranda Mills, National Director — Earth Observation, Navigation and Science of Astrium signed the contract on 26 April on the occasion of a ceremony celebrating 50 years of...

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...

Image 1 - New 'Alien' Particles Have Entered Our Solar System
2012-01-31 13:59:55

[ Watch the Video ] Researchers have measured neutral "alien" particles that have entered our solar system from interstellar space. The team used NASA's Interstellar Boundary Explorer (IBEX) spacecraft to find the neutral particles, which make up about half the material outside the heliosphere. The heliosphere is the bubble in which our Sun and planets reside and is formed by the interaction between the solar wind and the interstellar medium. Electrically charged particles cannot...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...
