Van Allen Probes

Karen C. Fox, NASA's Goddard Space Flight Center One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, called the Van Allen radiation belts. Recent data from the Van Allen Probes -- two nearly identical spacecraft that launched in 2012 -- address this question. The inner Van Allen radiation belt is fairly stable, but the outer one changes shape, size and composition in ways that scientists don't yet...

NASA Seeks Proposals For Science Instruments For Future Mission To Europa
2014-07-16 03:18:13

Dwayne Brown, NASA NASA has issued an Announcement of Opportunity (AO) for proposals about science instruments that could be carried aboard a future mission to Jupiter’s moon Europa. Selected instruments could address fundamental questions about the icy moon and the search for life beyond Earth. “The possibility of life on Europa is a motivating force for scientists and engineers around the world,” said John Grunsfeld, associate administrator for NASA’s Science Mission...

Preston Dyches, NASA Jet Propulsion Laboratory Twenty years ago, human and robotic eyes observed the first recorded impact between cosmic bodies in the solar system, as fragments of comet Shoemaker-Levy 9 slammed into the atmosphere of Jupiter. Between July 16 and July 22, 1994, space- and Earth-based assets managed by NASA's Jet Propulsion Laboratory in Pasadena, California, joined an armada of other NASA and international telescopes, straining to get a glimpse of the historic event: -...

NASA's New Horizons Spacecraft Less Than A Year From Pluto Flyby
2014-07-15 09:44:15

[ Watch the Video: ScienceCasts: One Year To Pluto ] Gerard LeBlond for redOrbit.com - Your Universe Online NASA says its New Horizons spacecraft is only one year away from Pluto, slated to make an historic flyby on July 14, 2015 and give the Earthlings never before seen images of the distant world. “Because Pluto has never been visited up-close by a spacecraft from Earth, everything we see will be a first. I know this will be an astonishing experience full of history making...

NASA Many scientists believe we are not alone in the universe. It's probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone -- just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations. What are the next steps to finding life elsewhere? Experts from NASA and its partner institutions addressed this question on Monday, July 14, at...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Space missions generally fall into three different categories: small, medium, and large. Dull naming conventions aside, the various mission types really tell the story of the scale of the projects. But make no mistake; even “small” missions can have a big impact. Recently, the European Space Agency (ESA) has been focusing more on medium and large-scale projects, but that is all changing. The forthcoming CHaracterising...

ESA's Venus Express Probe Is On The Rise One Final Time
2014-07-14 14:35:17

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The planet Venus has often been referred to as Earth’s Twin, or Earth’s Sister, because in many ways it bears a striking similarity to the world we call home. But while it is roughly the same size, similar mass, possesses a magnetic field, and maintains an atmosphere, there are also some very important differences. Perhaps the most significant departure is the exact nature of Venus’s atmosphere. Surrounding our...

Geometry
2014-01-02 10:21:51

Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC, geometry was put into an axiomatic form by...

Stellar Astrophysics

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Columbia launched from Kennedy Space Center on October 22, 1992 at 1:09 PM EDT and landed at Kennedy on November 1 at 9:05 AM EST. The shuttle orbited 159 times at an altitude of 163 nautical miles at an inclination of 28.45 degrees and travelled 4.1 million miles. The mission lasted 9 days, 20 hours, 56 minutes, and 13 seconds. The mission launched several satellites for international partners. The primary mission objectives were the deployment of the Laser Geodynamic Satellite II...
