Voyager Golden Record

Friday, June 15th, 2012

The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecraft, which were launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them.

“This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings.” – Jimmy Carter

“In the upper left-hand corner is an easily recognized drawing of the phonograph record and the stylus carried with it. The stylus is in the correct position to play the record from the beginning. Written around it in binary arithmetic is the correct time of one rotation of the record, 3.6 seconds, expressed in time units of 0,70 billionths of a second, the time period associated with a fundamental transition of the hydrogen atom. The drawing indicates that the record should be played from the outside in. Below this drawing is a side view of the record and stylus, with a binary number giving the time to play one side of the record – about an hour.

“The information in the upper right-hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals. The top drawing shows the typical signal that occurs at the start of a picture. The picture is made from this signal, which traces the picture as a series of vertical lines, similar to
ordinary television (in which the picture is a series of horizontal lines). Picture lines 1, 2 and 3 are noted in binary numbers, and the duration of one of the “picture lines,” about 8 milliseconds, is noted. The drawing immediately below shows how these lines are to be drawn vertically, with staggered “interlace” to give the correct picture rendition. Immediately below this is a drawing of an entire picture raster, showing that there are 512 vertical lines in a complete picture. Immediately below this is a replica of the first picture on the record to permit the recipients to verify that they are decoding the signals correctly. A circle was used in this picture to insure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction.

“The drawing in the lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. It shows the location of the solar system with respect to 14 pulsars, whose precise periods are given. The drawing containing two circles in the lower right-hand corner is a drawing of the hydrogen atom in its two lowest states, with a connecting line and digit 1 to indicate that the time interval associated with the transition from one state to the other is to be used as the fundamental time scale, both for
the time given on the cover and in the decoded pictures.

“Electroplated onto the record’s cover is an ultra-pure source of uranium-238 with a radioactivity of about 0.00026 microcuries. The steady decay of the uranium source into its daughter isotopes makes it a kind of radioactive clock. Half of the uranium-238 will decay in 4.51 billion years. Thus, by examining this two-centimeter diameter area on the record plate and measuring the amount of daughter elements to the remaining uranium-238, an extraterrestrial recipient of the Voyager spacecraft could calculate the time elapsed since a spot of uranium was placed aboard the spacecraft. This should be a check on the epoch of launch, which is also described by the pulsar map on the record cover.”

WASHINGTON, D.C. — NASA transferred space shuttle Discovery to the Smithsonian’s National Air and Space Museum during a ceremony Thursday, April 19, at the Stephen F. Udvar-Hazy Center in Chantilly, VA.

“Today, while we look back at Discovery’s amazing legacy, I also want to look forward to what she and the shuttle fleet helped to make possible,” said NASA Administrator Charles Bolden. “As NASA transfers the shuttle orbiters to museums across the country, we are embarked on an exciting new space exploration journey. Relying on American ingenuity and know-how, NASA is partnering with private industry to provide crew and cargo transportation to the International Space Station, while developing the most powerful rocket ever built to take the nation farther than ever before into the solar system.”

National Air and Space Museum Director, General John “Jack” Dailey said, “Discovery has distinguished itself as the champion of America’s shuttle fleet. In its new home, it will shine as an American icon, educating and inspiring people of all ages for generations to come. The Museum is committed to teaching and inspiring youngsters, so that they will climb the ladder of academic success and choose professions that will help America be competitive and successful in the world of tomorrow.”

In this new era of exploration, NASA will build the capabilities to send humans deeper into space than ever before. NASA is using the space station as a test bed and stepping stone for the journey ahead. The agency is changing the way it does business and fostering a commercial industry that will safely service low Earth orbit, so NASA can focus its energy and resources on sending astronauts to an asteroid by 2025 and eventually to Mars in the 2030s.

The space station is the centerpiece of NASA’s human spaceflight activities in low Earth orbit. It is fully staffed with an international crew of six, and American astronauts will continue to live and work there 24 hours a day, 365 days a year, as they have for more than 11 years. Part of the U.S. portion of the station has been designated as a national laboratory, and NASA is committed to using this unique resource for scientific research.

The station is testing exploration technologies such as autonomous refueling of spacecraft, advanced life support systems and human/robotic interfaces. Commercial companies are well on their way to providing cargo and crew flights to the station, allowing NASA to focus its attention on the next steps into our solar system.

The East Coast of the United States from Space

This Jan. 29 panorama of much of the East Coast, photographed by one of the Expedition 30 crew members aboard the International Space Station, provides a look generally northeastward: Philadelphia-New York City-Boston corridor (bottom-center); western Lake Ontario shoreline with Toronto (left edge); Montreal (near center). An optical illusion in the photo makes the atmospheric limb and light activity from Aurora Borealis appear “intertwined.”

Go here to view an image that explains how composite images like these are created: www.flickr.com/photos/gsfc/6803619953

Responding to public demand, NASA scientists created a companion image to the wildly popular ‘Blue Marble’ released last week (January 25, 2012). www.flickr.com/photos/gsfc/6760135001

The new image is a composite of six separate orbits taken on January 23, 2012 by the Suomi National Polar-orbiting Partnership satellite. Both of these new ‘Blue Marble’ images are images taken by a new instrument flying aboard Suomi NPP, the Visible Infrared Imaging Radiometer Suite (VIIRS).

Compiled by NASA Goddard scientist Norman Kuring, this image has the perspective of a viewer looking down from 7,918 miles (about 12,742 kilometers) above the Earth’s surface from a viewpoint of 10 degrees South by 45 degrees East. The four vertical lines of ‘haze’ visible in this image shows the reflection of sunlight off the ocean, or ‘glint,’ that VIIRS captured as it orbited the globe. Suomi NPP is the result of a partnership between NASA, NOAA and the Department of Defense.

Asteroid

Wednesday, September 28th, 2011

This infrared image from NASA’s Wide-field Infrared Survey Explorer, or WISE, showcases the Tadpole Nebula, a star-forming hub in the Auriga constellation about 12,000 light-years from Earth. As WISE scanned the sky, capturing this mosaic of stitched-together frames, it happened to catch an asteroid in our solar system passing by. The asteroid, called 1719 Jens, left tracks across the image. A second asteroid was also observed cruising by.

But that’s not all that WISE caught in this busy image — two natural satellites orbiting above WISE streak through the image, appearing as faint green trails. This Tadpole region is chock full of stars as young as only a million years old — infants in stellar terms — and masses over 10 times that of our sun. It is called the Tadpole nebula because the masses of hot, young stars are blasting out ultraviolet radiation that has etched the gas into two tadpole-shaped pillars, called Sim 129 and Sim 130. These “tadpoles” appear as the yellow squiggles near the center of the frame. The knotted regions at their heads are likely to contain new young stars. WISE’s infrared vision is helping to ferret out hidden stars such as these.

The 1719 Jens asteroid, discovered in 1950, orbits in the main asteroid belt between Mars and Jupiter. The space rock, which has a diameter of 19 kilometers (12 miles), rotates every 5.9 hours and orbits the sun every 4.3 years.

Twenty-five frames of the region, taken at all four of the wavelengths detected by WISE, were combined into this one image. The space telescope caught 1719 Jens in 11 successive frames. Infrared light of 3.4 microns is color-coded blue: 4.6-micron light is cyan; 12-micron-light is green; and 22-micron light is red.

WISE is an all-sky survey, snapping pictures of the whole sky, including everything from asteroids to stars to powerful, distant galaxies.

NASA Ocean Recovery

Tuesday, March 22nd, 2011

CAPE CANAVERAL, FLORIDA — For the first time, NASA has released high-definition video taken during the retrieval of solid rocket booster segments from the Atlantic Ocean. The solid rocket boosters provided 144 million horsepower of thrust for the final launch of space shuttle Discovery on its STS-133 mission.

After each shuttle launch, crew members of the Liberty Star and Freedom Star retrieval ships pull the spent boosters out of the ocean and return them to Hangar AF at Cape Canaveral Air Force Station in Florida. After they are processed, the boosters are transported to Utah, where they are refurbished and stored, if necessary.

The video includes high-definition video footage from the recovery ships and time-lapse footage of recovery efforts on Freedom Star.

The footage was captured with a Panasonic HPX 3700 high-definition, cinema-style camera with 1080 progressive scanning at 24 frames per second.

The video will be broadcast on NASA Television’s Video File. For NASA TV downlink information, schedules and links to streaming video, visit:
