"The beautiful and mysterious auroras are spectacular to watch, but they are actually a manifestation of violent space weather. This weather can create big problems here on Earth by disrupting power grids, satellites, air travel and even GPS signals. While auroras have fascinated observers for centuries, little had been known about their origin. But NASA is aiming to resolve this mystery with a new mission called THEMIS." (02:15)

In an interview aired on NASA Television during the International Space Station Update hour, NASA Flight Surgeon Ed Powers discussed how flight doctors work with crew members on board the station to keep the astronauts healthy. Powers also talked about some of the difficulties encountered in diagnosing patients who are not there in person and about the impacts of space medicine to life here on earth. (08:18)

The Global Precipitation Measurement (GPM) is an international satellite mission to provide next-generation observations of rain and snow worldwide every three hours. NASA and the Japan Aerospace Exploration Agency (JAXA) will launch a "Core" satellite carrying advanced instruments that will set a new standard for precipitation measurements from space. The data they provide will be used to unify precipitation measurements made by an international network of partner satellites to quantify when, where, and how much it rains or snows around the world.

To observe how winds move high in Earth's atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around, but scientists have no similar technique to study the turbulent atmosphere of the sun. So researchers were excited in December 2011, when Comet Lovejoy swept right through the sun's corona with its long tail streaming behind it. NASA's Solar Dynamics Observatory (SDO) captured images of the comet, showing how its long tail was buffeted by systems around the sun, offering scientists a unique way of observing movement as if they'd orchestrated the experiment themselves. Since comet tails have ionized gases, they are also affected by the sun's magnetic field, and can act as tracers of the complex magnetic system higher up in the atmosphere. Comets can also aid in the study of coronal mass ejections and the solar wind. (03:35)

Building satellites isn't easy. They're complex, expensive, and not to mention hard to make! This is why whenever NASA makes a new satellite--like the MAVEN mission to Mars--its scientists and engineers do everything they can to make sure it's done right.
Now, putting a satellite together is nothing like putting together, say, an office chair. A single bolt can take hours to install, and you can't even imagine how complex the electronics are! Find out more about
the whole process in this video. (01:28)

Jupiter's bright Equatorial Zone swirls with dark patches, dubbed "hot spots" for their infrared glow. These holes in the ammonia clouds at the top of the atmosphere allow a glimpse into Jupiter's darker, hotter layers below. In 1995 NASA's Galileo spacecraft dropped a probe directly into a hot spot, taking the first and only in situ measurements of Jupiter's atmosphere. Now, movies recorded by NASA's Cassini spacecraft reveal that hot spots are not just local weather phenomena, but are in fact linked to much larger-scale atmospheric structures called Rossby waves.

(03:52) Lately, the International Space Station has been flying through geomagnetic storms, giving astronauts an close-up view of the aurora borealis just outside their windows. These videos were taken by the crew of Expedition 30 on board the International Space Station. First, get an introduction into the beauty of aurorae.
1st Segment:
The sequence of shots was taken March 3, 2012 from 17:59:48 to 18:16:25 GMT, on a pass from eastern Kenya, near the Indian Ocean, to the South Indian Ocean, east of the Kerguelen Islands. This video begins as the ISS travels southeast from eastern Africa over the Arabian Sea and the Indian Ocean. The first land we see is that of the Mauritius and Reunion Islands east of Madagascar. The pass continues over the Indian Ocean, where there are heavy clouds blocking the view of the water. Finally, the Aurora Australis begins to appear, as well as a faded view of the Milky Way.
2nd Segment:
The sequence of shots was taken March 4, 2012 from 17:19:17 to 17:27:10 GMT, on a pass over the South Indian Ocean. This video again focuses on the Aurora Australis as the ISS passes over the South Indian Ocean, from northeast of the Kerugelen Islands to south of Australia. The streaks of the aurora are very visible and active in this video, as the ISS passes right over the green lights.
3rd Segment:
The sequence of shots was taken March 10, 2012 from 14:49:58 to 15:05:37 GMT, on a pass from the South Indian Ocean to southeast New Zealand. This video mainly focuses on the Aurora Australis over the Southern Hemisphere. As the ISS traveled southeast and then northeast, the crew captured the bands of the Aurora Australis as the Milky Way made an appearance in the star field.

When you navigate with a compass you can orient yourself thanks to Earth's global magnetic field. But on Mars, if you were to walk around with a compass it would haphazardly point from one anomaly to another, because the Red Planet does not possess a global magnetosphere. Scientists think that this lack of a protective magnetic field may have allowed the solar wind to strip away the Martian atmosphere over billions of years, and now NASA's MAVEN spacecraft will study this process in detail with its pair of ring core fluxgate magnetometers.

Since February 2011, the two spacecraft of NASA's the Solar Terrestrial Relations Observatory or STEREO mission have been providing scientists with unprecedented views of the far side of the sun.
The spacecraft travel at different speeds. This means that over time, the satellites become increasingly out of sync, appearing from Earth's perspective to drift farther apart, able to observe first the sides and eventually the far side of the sun. Now they are nearing each other once again, this time on the other side of the sun. During this period when the sun blocks Earth's view -- a geometrical position known in astronomy as a superior conjunction -- radio receivers on Earth will not be able to distinguish STEREO's signal from the sun's radiation.

NASA space-based observatories are making unprecedented new discoveries and revealing worlds never before seen. During a televised panel discussion of leading science and engineering experts at NASA Headquarters on Monday, July 14, a scientific and technological roadmap to lead to the discovery of potentially habitable worlds among the stars was addressed. The agency's next step, the James Webb Space Telescope (Webb telescope), was featured as a new tool that will continue to help scientists rewrite scientific textbooks long after its scheduled launch in 2018.

NASA's Radiation Belt Storm Probes (RBSP), the first twin-spacecraft mission designed to explore our planet's radiation belts, launched into the predawn skies. The two satellites, each weighing just less than 1,500 pounds, comprise the first dual-spacecraft mission specifically created to investigate this hazardous regions of near-Earth space, known as the radiation belts. These two belts, named for their discoverer, James Van Allen, encircle the planet and are filled with highly charged particles. The belts are affected by solar storms and coronal mass ejections and sometimes swell dramatically. When this occurs, they can pose dangers to communications, GPS satellites and human spaceflight.

On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled away from the sun at over 900 miles per second. This movie shows the ejection from a variety of viewpoints as captured by NASA's Solar Dynamics Observatory (SDO), NASA's Solar Terrestrial Relations Observatory (STEREO), and the joint ESA/NASA Solar Heliospheric Observatory (SOHO).
