[ Watch the Video: What Really Causes Space Weather? ] redOrbit Staff & Wire Reports - Your Universe Online Research published in Friday’s issue of the journal Science looks to shed new light on how changing environmental conditions in near-Earth space known as “space weather” can occur. Space weather is caused by solar storms – powerful eruptions of solar material and magnetic fields into interplanetary space – and can interfere with wireless communication and GPS...

NASA Assigns Two Spacecraft To New Moon Study Mission
2013-07-10 08:59:08

April Flowers for redOrbit.com - Your Universe Online After successful completion of their science objectives earlier this year, two NASA spacecraft have been assigned a new mission to study how solar wind electrifies, alters and erodes the moon's surface. The data collected could reveal valuable information for future explorers and give planetary scientists a hint of what's happening on other worlds around the Solar System. The new mission's name is ARTEMIS, or Acceleration,...

ASU Mars Education Program Wins Award From Science Magazine
2013-02-21 14:23:51

Arizona State University Letting secondary school students use an operating NASA spacecraft to take images of Mars is about as hands-on as science education can get. Nor are the students just aiming the space camera randomly. Instead, they are targeting an image on the Red Planet's surface to answer a scientific question about Mars that the students themselves have developed. That's the exciting premise of the award-winning Mars Student Imaging Project (MSIP). A key component of...

Understanding The Magnetosphere Better Than Ever With Help From THEMIS
2013-02-20 10:47:18

NASA On Earth, scientists can observe weather patterns, and more importantly can predict them, through the use of tens of thousands of weather observatories scattered around the globe. Up in the space surrounding Earth -- a space that seethes with its own space weather made of speeding charged particles and constantly changing magnetic fields that can impact satellites — there are only a handful of spacecraft to watch for solar and magnetic storms. The number of observatories has...

Geotail Mission Celebrates 20th Anniversary
2012-07-28 08:59:52

Lee Rannals for redOrbit.com - Your Universe Online Twenty years ago, the United States relationship with Japan showed just how restored it was since the second world war, as the two countries' space agencies launched a joint mission together. The Geotail mission launched into space aboard a Delta II launch vehicle 20 years ago from this week, kick-starting a set of coordinated missions known as the International Solar Terrestrial Physics (ISTP) project. ISTP studied the magnetic...

Tenth Anniversary Image From THEMIS
2012-03-01 04:19:57

The Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey spacecraft has completed an unprecedented full decade of observing Mars from orbit. THEMIS captured this image on Feb. 19, 2012, 10 years to the day after the camera recorded its first view of Mars. This image covers an area 11 by 32 miles (19 by 52 kilometers) in the Nepenthes Mensae region north of the Martian equator. The view depicts a knobby landscape where the southern highlands are breaking up as the terrain...

Image 1 - THEMIS Celebrates Five Years Of Service

[ Watch the Video ] People still talk about the launch. It was the first — and so far, only — time NASA has launched five satellites at one time. Carefully balanced inside a Delta II rocket, the five THEMIS (short for Timed History of Events and Macroscale Interactions during Substorms) spacecraft were launched into space from Cape Canaveral at 6:01 p.m. ET on February 17, 2007. The spacecraft were nestled in a ring shape, four around the outside and one on a middle pedestal. A...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
