Voyager: The Golden Record

It’s the 1970s, and we’re about to send two spacecraft (Voyager 1 & 2) into space. These two spacecraft will eventually leave our solar system and become the most distant man-made objects…ever. How can we leave our mark on them in the case that other spacefarers find them in the distant future?

The Golden Record.

We placed an ambitious message aboard Voyager 1 and 2, a kind of time capsule, intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record, a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth.

The Golden Record Cover

The outward facing cover of the golden record carries instructions in case it is ever found. Detailing to its discoverers how to decipher its meaning.

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. The drawing indicates that the record should be played from the outside in.

The information in the upper right-hand portion of the cover is designed to show how the pictures contained on the record are to be constructed from the recorded signals. The top drawing shows the typical signal that occurs at the start of the picture. The picture is made from this signal, which traces the picture as a series of vertical lines, similar to ordinary television. Immediately below shows how these lines are to be drawn vertically, with staggered “interlace” to give the correct picture rendition. Below that is a drawing of an entire picture raster, showing that there are 52 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 ensure 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.

The Contents

The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University and his associates. 

They assembled 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales and other animals. To this, they added musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages, and printed messages from President Carter and U.N. Secretary General Waldheim.

Listen to some of the sounds of the Golden Record on our Soundcloud page:

Golden Record: Greetings to the Universe

Golden Record: Sounds of Earth

Songs from Chuck Berry’s “Johnny B. Goode,” to Beethoven’s Fifth Symphony are included on the golden record. For a complete list of songs, visit: https://voyager.jpl.nasa.gov/golden-record/whats-on-the-record/music/

The 115 images included on the record, encoded in analog form, range from mathematical definitions to humans from around the globe. See the images here: https://voyager.jpl.nasa.gov/golden-record/whats-on-the-record/images/

Making the Golden Record

Many people were instrumental in the design, development and manufacturing of the golden record. 

Blank records were provided by the Pyral S.A. of Creteil, France. CBS Records contracted the JVC Cutting Center in Boulder, CO to cut the lacquer masters which were then sent to the James G. Lee Record Processing center in Gardena, CA to cut and gold plate eight Voyager records.

The record is constructed of gold-plated copper and is 12 inches in diameter. The record’s cover is aluminum and electroplated upon it is an ultra-pure sample of the isotope uranium-238. Uranium-238 has a half-life of 4.468 billion years.

2016 Sets Global Temperature Record

We just experienced the hottest year on record…again.

2016 was hotter than 2015, the previous record. And 2015 hotter than 2014, the previous record year.

These record temperatures are all part of a warming trend that dates back to the late-19th century, largely caused by human emissions of carbon dioxide and other gases into the atmosphere.

A lot of this warming trend has been in the last 35 years. In fact, 16 of the 17 warmest years on record have been since 2001.

To help us gather this data, planes and boats travel out from Antarctic research stations to gather information from the Arctic region, in addition to space-based observatories.

Scientists at our Goddard Institute for Space Studies analyze data from 6,300 weather stations, observations of sea surface temperature and Antarctic research stations, all to determine how the average surface temperature is changing.

Scientists at the National Oceanic and Atmospheric Administration separately analyze the same data to track global temperature.

The two agencies reached the same conclusion about 2016’s record-setting heat.

Variations in local weather mean parts of the globe did not experience a record-setting year. Some places still had snow, cold weather and below-record temperatures, but the overall global average was higher than any previous year.

For instance, according to NOAA the average temperature in the 48 contiguous United States was not quite as high as in 2015, which still holds the record.

A combination of space- and land-based measurements gives us a unique perspective on Earth, the only planet we know of that supports life.

Houston, We Have a Launch!

Today, three new crew members will launch to the International Space Station. NASA astronaut Jeff Williams, along with Russian cosmonauts Alexey Ovchinin and Oleg Skripochka, are scheduled to launch from the Baikonur Cosmodrome in Kazakhstan at 5:26 p.m. EDT. The three Expedition 47 crew members will travel in a Soyuz spacecraft, rendezvousing with the space station six hours after launch.

Traveling to the International Space Station is an exciting moment for any astronaut. But what if you we’re launching to orbit AND knew that you were going to break some awesome records while you were up there? This is exactly what’s happening for astronaut Jeff Williams.

This is a significant mission for Williams, as he will become the new American record holder for cumulative days in space (with 534) during his six months on orbit. The current record holder is astronaut Scott Kelly, who just wrapped up his one-year mission on March 1.

On June 4, Williams will take command of the station for Expedition 48. This will mark his third space station expedition…which is yet another record!

Want to Watch the Launch?

You can! Live coverage will begin at 4:30 p.m. EDT on NASA Television, with launch at 5:26 p.m.

Tune in again at 10:30 p.m. to watch as the Soyuz spacecraft docks to the space station’s Poisk module at 11:12 p.m.

Hatch opening coverage will begin at 12:30 a.m., with the crew being greeted around 12:55 a.m.
