Total Solar Eclipse Aug 21st, 2017

Megamovie App makes photographing the Total Solar Eclipse a Snap

The Eclipse Megamovie project has released an app that makes it easy for citizen scientists with smart phones to photograph the Aug. 21 total solar eclipse and upload the images to the project team; a collaboration between the Space Sciences Laboratory’s Multiverse education group and Google’s Making & Science initiative to provide a lasting photo archive for scientists studying the sun’s corona.

The Eclipse Megamovie Mobile app, created by Ideum, is available for Android phones through Google Play store and for iPhones through iTunes’ App Store.

When downloaded and installed, the app walks users through a simple process to point your smart phone at the sun and automatically starts taking photos. Photos begin 15 seconds before totality and throughout the total eclipse – which will last a maximum of 2 minutes, 40 seconds, depending on where you are – and 15 seconds after the total eclipse has ended to capture what is known as the “diamond ring” effect.

Delta IV Heavy Booster Cores Arrive for Parker Solar Probe

Framed by a series of cabbage palms, a United Launch Alliance Delta IV Heavy common booster core is transported by truck to Cape Canaveral Air Force Station’s Launch Complex 37 Horizontal Processing Facility after arriving at Port Canaveral. The Delta IV Heavy will launch NASA’s upcoming Parker Solar Probe mission.
The mission will perform the closest-ever observations of a star when it travels through the Sun’s atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection. Liftoff atop the Delta IV Heavy rocket is scheduled to take place from Cape Canaveral’s Space Launch Complex 37 in summer 2018.

Launch preparations are beginning to get off the ground for NASA’s upcoming Parker Solar Probe mission, scheduled to lift off in summer 2018 atop a United Launch Alliance Delta IV Heavy rocket.

Two of the three common booster cores comprising the rocket’s first stage have arrived on the company’s Mariner ship, which delivered the components to Port Canaveral in Florida. From there the cores were offloaded and transported to the Horizontal Processing Facility at Cape Canaveral Air Force Station’s Space Launch Complex 37.

Van Allen Probes Surf through Waves in Space

The space surrounding our planet is full of restless charged particles and roiling electric and magnetic fields, which create waves around Earth. One type of wave, plasmaspheric hiss, is particularly important for removing charged particles from the Van Allen radiation belts, a seething coil of particles encircling Earth, which can interfere with satellites and telecommunications. A new study published in Journal of Geophysical Research using data from NASA’s Van Allen Probes spacecraft has discovered that hiss is more complex than previously understood.

The new study looked at a newly identified population of hiss waves at a lower frequency than usually studied. These low-frequency hiss waves are particularly good at cleaning out high-energy particles — those that can cause damage to satellites — from the radiation belts. The authors of the study noticed that low-frequency waves are actually a separate and unique population, tending to cluster in different regions around Earth compared to their high-frequency counterparts.
