25th Anniversary of Voyager 2 Flyby of Triton Commemorated With Movie

Wed August 27, 2014

Triton, Neptune’s largest moon, received a visit from Voyager 2 back on August 25, 1989. Voyager 2 passed within 40,000 kilometers of Triton and took lots of images. Now, for the first time, and to commemorate the 25th anniversary of this dramatic encounter, the images have been gathered into a movie. The resolution is 600 meters per pixel and is in orange, green and blue (showing Triton in approximately natural colors).

It’s a really fast flyby and the video starts with Voyager 2 about 3 days out from Triton, travelling at a speed of approx. 25 kilometers per second, passing over the unlit north pole, pivoting to see the departing moon (now visible as a diminishing crescent) and then ending about a week on the outbound trajectory. Triton is 2706 kilometers across.

The new Triton map has a resolution of 1,970 feet (600 meters) per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton’s natural colors. Voyager’s “eyes” saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images.

Watch Live NASA’s LDSD ‘Flying Saucer’ Test June 2014 Via Onboard Cameras

Tue June 3, 2014

This video presents “LDSD: We Brake for Mars (Part 1).”

  • NASA and JPL are testing a supersonic parachute under Mars-like conditions for future exploration.

This artist's concept shows the test vehicle for NASA's LDSD, designed to test landing technologies for future Mars missions. A balloon will lift the vehicle to high altitudes, where a rocket will take it even higher, to the top of the stratosphere, at several times the speed of sound.

Celebrate Earth Day 2014: NASA’s #GlobalSelfie Event + Celebratory Events in Canada

Tue April 22, 2014

This video presents “Earth Day 2014 Promo.”

  • Enjoy the beautiful scenery on Earth as NASA takes part in a worldwide celebration of Earth Day.
  • Today, April 22, is #EarthDay. Are you ready for your #GlobalSelfie?
  • Join NASA and the world celebrate environmental awareness with the agency’s #GlobalSelfie event.

NASA: #Global Selfie Sign for Earth Day 2014

NASA: #GlobalSelfie Sign for Earth Day 2014

NASA invites you — and everyone else on the planet — to take part in a worldwide celebration of Earth Day this year with the agency’s #GlobalSelfie event.

Earth Right Now Campaign

  • The year 2014 is a big one for NASA Earth science.
  • Five NASA missions designed to gather critical data about our home planet are launching this year to expand our understanding of Earth’s changing climate and environment.
  • NASA is marking this big year for Earth science with a campaign called Earth Right Now, and as part of this campaign the agency is asking for your help this Earth Day, April 22.

“NASA astronauts brought home the first ever images of the whole planet from space. Now NASA satellites capture new images of Earth every second. For Earth Day we are trying to create an image of Earth from the ground up while also fostering a collection of portraits of the people of Earth. Once those pictures stream around the world on Earth Day, the individual pictures tagged #GlobalSelfie will be used to create a mosaic image of Earth — a new “Blue Marble” built bit by bit with your photos.”

  • On Earth Day, NASA is asking you to step outside and take a picture of yourself wherever you are on Earth. Then post it to social media using the hashtag #GlobalSelfie.
NASA's "Earth Now" App

NASA’s “Earth Now” App

  • NASA’s FREE “Earth Now” Apple and Android app “immerses users in dazzling visualizations of near-real-time global climate data from NASA’s fleet of Earth science satellites.”

Today, April 22, is Earth Day. “What are you doing to show your love for the planet?”

NASA on Flickr – Real ‘Gravity’ Space Photos

Sat March 15, 2014

The Gravity movie has generated lots of interest on space missions. However, as Hollywood would have it, it is over-dramatized and no astronauts could survive accidents of the sort depicted in the movie.

Not to be outdone by — and taking advantage of — the interest and popularity of the movie, NASA has posted “Real-Life Images from Space” on Flickr for our enjoyment.

NASA Asks What are the “Mysterious Green Patches on the Sky”: Airglow Phenomenon Photography?

Tue October 1, 2013

This video presents “Hopewell Rocks perseid meteor shower time lapse.”

  • Kevin Snair filmed perseid meteor shower time lapse at enchanting Hopewell Rocks in New Brunswick, Canada from before twilight August 11 to shortly after 3:00 am August 12.
  • The green ‘clouds’  are visible in this silent video at 25 sec. to 28 sec. interval.

NASA astronomers are asking viewers what are the “Mysterious Green Patches on the Sky,” as they ponder the significance of these green images.

Snair explained that the green ‘clouds’ result from airglow phenomenon which is very weak emission of light by Earth’s atmosphere so that the night sky is never completely dark.

Another airglow phenomenon was captured on 15 September 2011 in the following photograph featuring

The Hubble Space Telescope Turns 23 and Takes New Stunning Horsehead Nebula Photo

Sun April 21, 2013

The Hubble Space Telescope, launched on April 24, 1990, has returned many stunning images of the cosmos. To celebrate its 23rd year, NASA used it to take a new — and stunning — infrared photo of the iconic Horsehead Nebula. The infrared photo was taken by the telescope’s Wide Field Camera 3 installed by spacewalking astronauts in 2009. The Hubble is expected to continue operating through April 2016. Its successor, the James Webb Space Telescope, is optimized to view in infrared light and is slated to blast off in 2018.
