NASA Program Gives Students Access To Astronauts
On June 23, NASA astronaut Jack Fischer spoke with 22 Girl Scouts of North East Ohio, while he was aboard the International Space Station. More than 400 people attended the event, with many more watching live footage online.
When the first crew of astronauts flies aboard the Orion spacecraft, they will be able to look through a window and view the moon and Earth from their deep-space vantage point. The window panel that will provide that view is ready for shipment to NASA. AMRO Fabricating Corp., of South El Monte, California, has completed a section of the Orion pressure vessel, or underlying structure of the spacecraft that will send astronauts farther than humans have ever traveled before on Exploration Mission-2 (EM-2).

A technical challenge that NASA is working to solve is how to maintain very cold liquid propellants to be used as fuel for deep space missions. Heat intercept concepts such as advanced insulation blankets, foam insulation and vapor-based cooling will be evaluated with the Structural Heat Intercept Insulation Vibration Evaluation Rig or SHIIVER, which arrived Aug. 10 at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for application of its first round of insulation.
TRAPPIST-1 Is Older Than Our Solar System
Scientists now have a good estimate for the age of one of the most intriguing planetary systems discovered to date — TRAPPIST-1, a system of seven Earth-size worlds orbiting an ultra-cool dwarf star about 40 light-years away. Researchers say in a new study that the TRAPPIST-1 star is quite old: between 5.4 and 9.8 billion years. This is up to twice as old as our own solar system, which formed some 4.5 billion years ago.
NASA has selected six astrophysics Explorers Program proposals for concept studies. The proposed missions would study gamma-ray and X-ray emissions from clusters of galaxies and neutron star systems, as well as infrared emissions from galaxies in the early universe and atmospheres of exoplanets, which are planets outside of our solar system.
NASA’s James Webb Space Telescope began a nearly 100-day cryogenic test in a giant chamber in Texas in mid-July. Components of the Webb have previously endured similar tests to ensure they would function in the cold environment of space. Now all of those components are being tested together in the giant thermal vacuum known as Chamber A at NASA’s Johnson Space Center in Houston.
A novel mission concept involving two CubeSats connected by a thin, miles-long tether could help scientists understand how the Moon got its mysterious “tattoos” — swirling patterns of light and dark found at more than 100 locations across the lunar surface.
New Clues To Universe’s Structure Revealed
What is our universe made of, and has its composition changed over time? Scientists have new insights about these fundamental questions, thanks to an international collaboration of more than 400 scientists called the Dark Energy Survey (DES). Three scientists from NASA’s Jet Propulsion Laboratory in Pasadena, California, are part of this group that is helping to further our understanding of the structure of the universe.
Our recently coordinated Frontiers Research Topic on Coronal Magnetometry was designed to provide a forum for comparing and coordinating these research methods, and for discussing future opportunities.

The New Horizons spacecraft is in good health and flying farther each day. In fact, we’re hightailing it through the Kuiper Belt, the third zone of our solar system, at a rate of about 1 million kilometers every day. Science never sleeps!
A new experiment set for an Aug. 14 launch to the International Space Station will provide an unprecedented look at a rain of particles from deep space, called cosmic rays, that constantly showers our planet. The Cosmic Ray Energetics And Mass mission destined for the International Space Station (ISS-CREAM) is designed to measure the highest-energy particles of any detector yet flown in space.
Something New Under The Sun
Stars like the Sun have to get rid of the heat generated by thermonuclear reactions in their centers. The Sun’s secret is vigorous convection, particularly in the outer third of the Sun closest to its surface. Like a pot of boiling water, hot fluid moves upward and cooler fluid moves downward, carrying heat outwards toward the surface of the star. Many astrophysicists haven’t actually understood how this aspect of the Sun worked –– until JILA former senior research associate Nick Featherstone and senior research associate Brad Hindman set the record straight.
Wispy, early-season clouds resembling Earth’s ice-crystal cirrus clouds move across the Martian sky in some new image sequences from NASA’s Curiosity Mars rover. These clouds are the most clearly visible so far from Curiosity, which landed five years ago this month about five degrees south of Mars’ equator. Clouds moving in the Martian sky have been observed previously by Curiosity and other missions on the surface of Mars, including NASA’s Phoenix Mars Lander in the Martian arctic nine years ago.
NASA’s Solar Dynamics Observatory Watches A Sunspot
On July 5, 2017, NASA’s Solar Dynamics Observatory (SDO) watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun. The satellite continued to track the region as it grew and eventually rotated across the Sun and out of view on July 17.
Objects in a vacuum, like the Webb telescope inside of Chamber A, primarily cool through a heat-transfer process called radiation. For an object to radiatively cool, it must be in view of another, colder object. The heat from the warmer object (the telescope) transfers to the colder object (the surrounding shrouds) without the need of a medium (such as air).
25 Years Of Global Sea Level Data, And Counting
NASA recently marked the 25th anniversary of the launch of a revolutionary ocean research vessel — a space “ship.” As the NASA/CNES Topex-Poseidon satellite ascended into orbit, it ushered in a new era of oceanography with the first highly accurate, global measurements of sea levels. That mission and its three successors, all named Jason, have continuously mapped global ocean currents and tides; opened our eyes to the global reach of El Niño and other climate events; created a quarter-century-long, extraordinarily precise record of global and regional sea level rise; and enabled improved forecasts of extreme weather events such as hurricanes, floods and droughts.
