Planets of the Solar System: Tilts and Spins

HD 3d printing pizza on a contract from NASA HD Systems and Materials Research Corporation (SMRC) is experimenting with 3D printing of food on a contract from NASA. Their pizza printer uses open source technology to "print" dough, sauce and cheese onto a platform with a heating element underneath. The pizzas cannot be tasted yet because NASA requires clinical trials first!

What is Remote Sensing? CIRES Fellow and NASA Chief Scientist Waleed Abdalati and CIRES Fellow Steve Nerem explain Remote Sensing and how it is used to study our planet.

Our Milky Way Galaxy: How Big is Space? When we talk about the enormity of the cosmos, it’s easy to toss out big numbers – but far more difficult to wrap our minds around just how large, how far, and how numerous celestial bodies really are. How big is our Milky Way Galaxy and how far away are exoplanets, the planets beyond our solar system?

NASA's Plan for a Failed Apollo 11 What would have happened had Armstrong and Aldrin become stranded on the Moon's surface in 1969?

The Ozone Hole: Closing the Gap In the 1980s, scientists began to realize that ozone-depleting chemicals, such as chlorofluorocarbon (CFCs), were creating a thin spot—a hole—in the ozone layer over Antarctica. Through an international effort to decrease the use of CFCs, the ozone layer is starting to mend, and scientists believe it should mostly recover by the middle of the 21st century. This series of satellite images shows the ozone hole on the day of its maximum depth from 1979 through 2018.

NASA ScienceCasts : New Science from Jupiter As the Juno spacecraft orbits Jupiter, new discoveries about the giant planet continue to be made.

ScienceCasts: Close Encounter with Enceladus NASA's Cassini Spacecraft is about to make a daring plunge through one of the plumes emerging from Saturn's moon Enceladus.

ScienceCasts: A Display of Lights Above the Storm Transient Luminous Events (TLEs) are flashes and glows that appear above storms and are results of activity occurring in and below those storms. Researchers are working to better understand lightning and thunderstorms, how they form and develop over time, and why storms produce different TLEs in different circumstances.

ScienceCasts: Hubble’s Contentious Constant There are two leading ways to measure the universe's rate of expansion, and for fifteen years, they more or less agreed with one another. Not anymore, and that’s a big deal.

NASA's Garbage Patch Visualization Experiment NASA created a visualization of the ocean garbage patches using data from floating, scientific buoys that NOAA has been distributing in the oceans for the last 35-years. Video Credit: NASA's Scientific Visualization Studio Complete transcript: Hi, it’s Greg Shirah from NASA’s Scientific Visualization Studio. We wanted to see if we could visualize the so-called ocean garbage patches. We start with data from floating, scientific buoys that NOAA has been distributing in the oceans for the last 35-years represented here as white dots. Let's speed up time to see where the buoys go... Since new buoys are continually released, it's hard to tell where older buoys move to. Let's clear the map and add the starting locations of all the buoys… Interesting patterns appear all over the place. Lines of buoys are due to ships and planes that released buoys periodically.If we let all of the buoys go at the same time, we can observe buoy migration patterns. The number of buoys decreases because some buoys don't last as long as others. The buoys migrate to 5 known gyres also called ocean garbage patches. We can also see this in a computational model of ocean currents called ECCO-2.We release particles evenly around the world and let the modeled currents carry the particles. The particles from the model also migrate to the garbage patches. Even though the retimed buoys and modeled particles did not react to currents at the same times, the fact that the data tend to accumulate in the same regions show how robust the result is.

NASA ScienceCasts: You Light Up Our Night People around the world have the opportunity to participate in the study of comet 46P/Wirtanen as it has a close approach with Earth in December of 2018.

NASA | NASA selects OSIRIS-REx as New Frontiers Mission OSIRIS-Rex will visit asteroid 1999 RQ36 and return with samples that may hold clues to the origin of the solar system and life on Earth. For the mission, NASA has selected the team led by Principal Investigator Dr. Michael Drake from the University of Arizona. NASA GSFC will manage the mission. Lockheed Martin will build the spacecraft.

NASA ScienceCasts: Cosmic Bow Shocks Bow shocks form across the universe, and studying bow shocks can reveal many cosmic secrets.

Planetary Formation: James Webb Space Telescope Science Stars and planets form in the dark, inside vast, cold clouds of gas and dust. The James Webb Space Telescope's large mirror and infrared sensitivity will let astronomers peer inside dusty knots where the youngest stars and planets are forming. These videos were developed to highlight the science that will be peformed by the James Webb Space Telescope.
