2017 Hurricanes and Aerosols Simulation

By: NASA Goddard

Originally published on Nov 13, 2017

How can you see the atmosphere? By tracking what is carried on the wind. Tiny aerosol particles such as smoke, dust, and sea salt are transported across the globe, making visible weather patterns and other normally invisible physical processes.

This visualization uses data from NASA satellites, combined with mathematical models in a computer simulation allowing scientists to study the physical processes in our atmosphere. By following the sea salt that is evaporated from the ocean, you can see the storms of the 2017 hurricane season.

During the same time, large fires in the Pacific Northwest released smoke into the atmosphere. Large weather patterns can transport these particles long distances: in early September, you can see a line of smoke from Oregon and Washington, down the Great Plains, through the South, and across the Atlantic to England.

Dust from the Sahara is also caught in storms sytems and moved from Africa to the Americas. Unlike the sea salt, however, the dust is removed from the center of the storm. The dust particles are absorbed by cloud droplets and then washed out as it rains.

Advances in computing speed allow scientists to include more details of these physical processes in their simulations of how the aerosols interact with the storm systems.

Fidget spinner spinning in space!

By: NASA Johnson

Originally published on Oct 13, 2017

A fidget spinner in space! How long does it spin? I’m not sure, but it’s a great way to experiment with Newton’s laws of motion!

Allowing the fidget spinner to float reduces the bearing friction by permitting the rate of the central ring and outer spinner to equalize, and the whole thing spins as a unit.

NASA Jets Chase The Total Solar Eclipse

By: NASA Goddard

Originally published on Jul 25, 2017

For most viewers, the Aug. 21, 2017, total solar eclipse will last less than two and half minutes. But for one team of NASA-funded scientists, the eclipse will last over seven minutes. Their secret? Following the shadow of the Moon in two retrofitted WB-57F jet planes. Amir Caspi of the Southwest Research Institute in Boulder, Colorado, and his team will use two of NASA’s WB-57F research jets to chase the darkness across America on Aug. 21. Taking observations from twin telescopes mounted on the noses of the planes, Caspi will capture the clearest images of the Sun’s outer atmosphere — the corona — to date and the first-ever thermal images of Mercury, revealing how temperature varies across the planet’s surface.

World’s First Live 360 Rocket Launch: Orbital ATK CRS-7

 

By: NASA

Streamed live

NASA, in coordination with United Launch Alliance (ULA) and Orbital ATK, will broadcast the world’s first live 360-degree stream of a rocket launch. This stream will begin at approximately 11:00a.m. EDT on April 18th, and will last until the rocket is out of sight. This stream enables you to look around in 360 degrees -as if you were actually standing on the launch pad.

The Orbital ATK CRS-7 resupply mission to the International Space Station is scheduled to launch during a 30 minute window opening at 11:11a.m. EDT. Orbital ATK’s Cygnus spacecraft will launch on a ULA Atlas V rocket carrying more than 7,600 pounds of science research, crew supplies and hardware to the orbiting laboratory.

NASA & TRAPPIST-1: A Treasure Trove of Planets Found

 

By: NASA Jet Propulsion Laboratory

Originally published on Feb 22, 2017

Seven Earth-sized planets have been observed by NASA’s Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone.

Over 21 days, NASA’s Spitzer Space Telescope measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone, where liquid water might be found.

The video features interviews with Sean Carey, manager of the Spitzer Science Center, Caltech/IPAC; Nikole Lewis, James Webb Space Telescope project scientist, Space Telescope Science Institute; and Michaël Gillon, principal investigator, TRAPPIST, University of Liege, Belgium.

The system has been revealed through observations from NASA’s Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.

NASA’s Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA’s Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at Caltech in Pasadena. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.

Jeff’s Earth – 4K

 

By: NASA Johnson

Originally published on Dec 29, 2016

The first time you see Planet Earth from space, it’s stunning; when you’ve spent 534 days in space—more than any other American—it still is! On his most recent trip the International Space Station NASA astronaut Jeff Williams used an Ultra High Definition video camera that he pointed at the planet 250 miles below; here he shares some of those images, and talks about the beauty of the planet, the variety of things to see, and the value of sharing that perspective with everyone who can’t go to orbit in person.
