NASA, Techshot And Tupperware Brands Team Up To Improve Plant Growth Aboard ISS

July 25, 2017 – The National Aeronautics and Space Administration (NASA), Techshot Inc., and Tupperware Brands Corporation (Tupperware) are jointly developing an improved system for growing plants aboard the International Space Station (ISS). Since 2014, astronaut farmers aboard the ISS have been growing a variety of leafy vegetables and colorful flowers inside the Vegetable Production System, otherwise known as the ‘Veggie’ facility. However, NASA is always seeking to improve upon existing technologies, while reducing its need for resources such as crew time. Read More


Ring-Bow

July 25, 2017 – Although the rings lack the many colors of the rainbow, they arc across the sky of Saturn. From equatorial locations on the planet, they’d appear very thin since they would be seen edge-on. Closer to the poles, the rings would appear much wider; in some locations (for parts of the Saturn’s year), they would even block the sun for part of each day. Read More


Large, Distant Comets More Common Than Previously Thought

July 25, 2017 – Comets that take more than 200 years to make one revolution around the Sun are notoriously difficult to study. Because they spend most of their time far from our area of the solar system, many “long-period comets” will never approach the Sun in a person’s lifetime. In fact, those that travel inward from the Oort Cloud — a group of icy bodies beginning roughly 186 billion miles (300 billion kilometers) away from the Sun — can have periods of thousands or even millions of years.

In the heart of baseball season, NASA completed its equivalent of a clean inning, successfully testing the third RS-25 flight controller for use on the new Space Launch System (SLS) deep space rocket. Engineers conducted a 500-second test of RS-25 Engine Controller Unit No. 5 on the A-1 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, July 25, 2017.


NASA’s Venus Chamber Breaks Record With Completion Of 80-Day Test

After an 80-day test at Venus surface conditions and a two-week cooling period, samples were removed from Glenn’s Extreme Environments Rig (GEER) at NASA’s Glenn Research Center in Cleveland, July 13, nearly doubling the facility’s previous duration record of 42 days. This new record puts researchers one step closer to understanding the effect a long-duration exposure to Venus’ atmosphere has on materials. With this knowledge, technology can be developed to allow for future missions to our sister planet.


Landsat ‘Sees In The Dark’ The Evolution Of Antarctica’s Delaware-Sized Iceberg

As Antarctica remains shrouded in darkness during the Southern Hemisphere winter, the Thermal Infrared Sensor (TIRS) on Landsat 8 captured a new snap of the 2,240-square-mile iceberg that split off from the Antarctic Peninsula’s Larsen C ice shelf on July 10-12. The satellite imagery is a composite of Landsat 8 as it passed on July 14 and July 21 and shows that the main berg, A-68, has already lost several smaller pieces. The A-68 iceberg is being carried by currents northward out of its embayment on the Larsen C ice shelf. The latest imagery also details a group of three small, not yet released icebergs at the north end of the embayment.


Investigation Tests New Methods Of Water Recycling In Space

Sometimes the best solution to a complex problem is the simplest one. That’s the approach that the Capillary Structures for Exploration Life Support (Capillary Structures) team took when designing the fluid physics investigation aboard the International Space Station. The Capillary Structures investigation uses capillary action, or the ability for a liquid to flow through a narrow spaces, such as small tubes, to move liquids and gases in microgravity, a task that can’t be tested in Earth’s gravity environment.

Art Richmond was awarded the 2017 Coupling Energetic Dynamics Atmospheric Research (CEDAR) Distinguished lecture for his fundamental contributions to upper atmosphere and ionosphere science over several decades. Art is a world-leading expert on ionospheric electrodynamics, and made key contributions to the CEDAR community through his work on the disturbance dynamo, electrodynamical coupling of the thermosphere and ionosphere system, wind dynamo effects at mid- and low-latitudes, the equatorial electrojet, the development of an empirical model of daytime electric fields, and the study of evening low-latitude electrodynamics.
