ISS Timelapse: Aurora Australis
The photographs used to make this video were taken on September 17, 2011 from 17:22:27 to 17:37:21 GMT from the International Space Station (ISS). This image sequence begins over the Indian Ocean halfway between Madagascar and Antarctica. Aurora Australis is present for the first ⅔rds of the video, then Australis comes into view. Yellow lights near the coast show the presence of cities, while interior oragne lights indicate brush fires.

The Secrets behind Earth’s Multi-colored Glow
Read moreWhat does our planet look like from space? Most are familiar with the beloved images of the blue marble or pale blue dot — Earth from 18,000 and 3.7 billion miles away, respectively. But closer to home, within the nearest region of space, you might encounter an unfamiliar sight. If you peer down on Earth from just 300 miles above the surface, near the orbit of the International Space Station, you can see vibrant swaths of red and green or purple and yellow light emanating from the upper atmosphere. This is airglow. Airglow occurs when atoms and molecules in the upper atmosphere, excited by sunlight, emit light in order to shed their excess energy. Or, it can happen when atoms and molecules that have been ionized by sunlight collide with and capture a free electron. In both cases, they eject a particle of light — called a photon — in order to relax again. The phenomenon is similar to auroras, but where auroras are driven by high-energy particles originating from the solar wind, airglow is energized by day-to-day solar radiation. ||

ICON Pre-Launch Live Shots
Read moreB-roll and canned interviews will be added on Wednesday, Oct 24 by 6:00pm || NASA's Mission to Explore the Connection Between Earth’s Weather and Space Launches Next WeekWhat happens in space doesn’t stay in space. Where Earth and space meet, winds from weather patterns ripple upward while solar energy streams down from above, forming a complex system that affects everyday technologies we rely on.Next week, NASA will launch the Ionospheric Connection Explorer (ICON) to study this dynamic region of Earth’s upper atmosphere, which is home to colorful auroras, communication satellites, and humans living aboard the International Space Station.Join NASA scientists from 6:00 a.m. to 12:00 p.m. EDT on Thursday, October 25 – the day before launch – to learn about ICON and the ever-changing conditions in space, known as space weather. To schedule an interview, fill out THIS FORM. suggested questions 1. Just like the weather here on Earth, the conditions in space are constantly changing. What’s today’s space weather forecast?2. From 360 miles above Earth, ICON will see beautiful bright swaths of red and green light in the atmosphere. What is this colorful glow?3. How could ICON’s research help protect technology we use on Earth?4. What else is NASA doing to study space weather?5. Where can we learn more? satellite coordinatesHD Satellite Coordinates for G17-K17/Upper: Galaxy 17 Ku-band Xp 17 Slot Upper| 91.0 ° W Longitude | DL 12049.0 MHz |Horizontal Polarity | QPSK/DVB-S | FEC 3/4 | SR 13.235 Mbps | DR 18.2954 MHz | HD 720p | Format MPEG2 | Chroma Level 4:2:0 | Audio Embedded ** Contact michelle.z.handleman@nasa.gov or 301-286-0918 with questions.

A Total Solar Eclipse Revealed Solar Storms 100 Years Before Satellites
Read moreEclipses set the stage for historic science. NASA is taking advantage of the Aug. 21, 2017 eclipse by funding 11 ground-based scientific studies. As our scientists prepare their experiments for next week, we're looking back to an historic 1860 total solar eclipse, which many think gave humanity our first glimpse of solar storms — called coronal mass ejections — 100 years before scientists first understood what they were.Scientists observed these eruptions in the 1970s during the beginning of the modern satellite era, when satellites in space were able to capture thousands of images of solar activity that had never been seen before. But in hindsight, scientists realized their satellite images might not be the first record of these solar storms. Hand-drawn records of an 1860 total solar eclipse bore surprising resemblance to these groundbreaking satellite images.Eclipse archive imagery from: http://mlso.hao.ucar.edu/hao-eclipse-archive.php ||
