\"Pale<\/p>\n

The Pale Blue Dot is a photograph of Earth taken Feb. 14, 1990, by NASA\u2019s Voyager 1 at a distance of 3.7 billion miles (6 billion kilometers) from the Sun. The image inspired the title of scientist Carl Sagan\u2019s book, \u201cPale Blue Dot: A Vision of the Human Future in Space,\u201d in which he wrote: \u201cLook again at that dot. That\u2019s here. That\u2019s home. That\u2019s us.\u201d The above image, \u201cPale Blue Dot Revisited,\u201d was created in 2020 for the 30th anniversary of the iconic picture. The updated version used modern image-processing software and techniques to revisit the well-known Voyager view, while attempting to respect the original data and intent of those who planned the images.

The Pale Blue Dot is a photograph of Earth taken on Feb. 14, 1990, by NASA\u2019s Voyager 1 spacecraft. Earth appears as a tiny speck of light suspended in a sunbeam against the vastness of space.<\/p>\n

Voyager 1 was speeding out of the solar system \u2014 beyond Neptune and about 3.7 billion miles (6 billion kilometers) from the Sun \u2014 when mission managers commanded it to look back toward home for a final time. It snapped a series of 60 images that were used to create the first \u201cfamily portrait\u201d of our solar system.<\/p>\n

The picture that would become known as the Pale Blue Dot shows Earth within a scattered ray of sunlight. Voyager 1 was so far away that \u2014 from its vantage point \u2014 Earth was just a point of light about a pixel in size.<\/p>\n

Figure 1 shows the location of each image.<\/p>\n

The Family Portrait<\/p>\n

In addition to Earth, Voyager 1 captured images of Neptune, Uranus, Saturn, Jupiter, and Venus. A few key members didn\u2019t show up in the shot: Mars was obscured by scattered sunlight bouncing around in the camera, Mercury was too close to the Sun, and dwarf planet Pluto was too tiny, too far away, and too dark to be detected.<\/p>\n

The images gave humans an awe-inspiring and unprecedented view of their home world and its neighbors. Like Earth, each planet appears as just a speck of light (Uranus and Neptune appear elongated due to spacecraft motion during their 15-second camera exposures).<\/p>\n

Finding a way to display the images and capture the sheer scale of Voyager\u2019s accomplishment proved challenging. NASA\u2019s Jet Propulsion Laboratory \u2014 which built and manages the Voyager probes \u2014 mounted the entire mosaic on a wall in its Theodore von K\u00e1rm\u00e1n Auditorium and it covered over 20 feet.<\/p>\n

Members of the Voyager imaging team said in a 2019 research paper that the image of Earth on the wall had to be replaced often because so many people touched it.<\/p>\n

The family portrait remains the first and only time a spacecraft has attempted to photograph our home solar system. Only three spacecraft have been capable of making such an observation from such a distance: Voyager 1, Voyager 2 and New Horizons.<\/p>\n

Sagan\u2019s Dream Shot<\/p>\n

Carl Sagan played a leading role in the U.S. space program. The prominent planetary scientist was a consultant and adviser to NASA beginning in the 1950s. He briefed the Apollo astronauts before their flights to the Moon.<\/p>\n

In his role as a visiting scientist at JPL, Sagan helped design and manage the Mariner 2 mission to Venus; the Mariner 9, Viking 1, and Viking 2 trips to Mars; the Voyager 1 and Voyager 2 missions to the outer solar system, and the Galileo mission to Jupiter.<\/p>\n

Sagan also was a member of the Voyager Imaging Team. He had the original idea in 1981 to use the cameras on one of the two Voyager spacecraft to image Earth. He realized that because the spacecraft were so far away the images might not show much. This was precisely why Sagan and other members of the Voyager team felt the images were needed \u2014 they wanted humanity to see Earth\u2019s vulnerability, and that our home world is just a tiny, fragile speck in the cosmic ocean.<\/p>\n

On Feb. 13, 1990, Voyager 1 warmed up its cameras for three hours. Then the spacecraft\u2019s science platform was pointed at Neptune and the observations began.<\/p>\n

After Neptune, it took images of Uranus, Saturn, Mars, the Sun, and then Jupiter, Earth, and Venus. The Earth images were taken at 04:48 GMT on Feb. 14, 1990, just 34 minutes before Voyager 1 powered off its cameras forever.<\/p>\n

It took until May 1, 1990 \u2014 and four separate communications passes with NASA\u2019s Deep Space Network \u2014 for all the image data to finally arrive back on Earth. Voyager 1 had captured images of six of the seven planets targeted as well as the Sun.<\/p>\n

In his subsequent book \u201cPale Blue Dot: A Vision of the Human Future in Space,\u201d Sagan wrote of the image: \u201cThat\u2019s here. That\u2019s home. That\u2019s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives\u2026 on a mote of dust suspended in a sunbeam.\u201d<\/p>\n

\u201cThere is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world,\u201d he said. \u201cTo me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we\u2019ve ever known.\u201d<\/p>\n

About the Photographer<\/p>\n

Voyager 1 was launched Sept. 5, 1977, just days after its twin \u2014 Voyager 2 \u2014 on Aug. 20. Because it was on a faster route to the mission\u2019s first encounter, at Jupiter, Voyager 1 overtook Voyager 2 on Dec. 15, 1977. (This was the reason for the order of their naming.)<\/p>\n

Voyager 1 flew past Jupiter on March 5, 1979, and Saturn on Nov. 12, 1980.<\/p>\n

After snapping the Pale Blue Dot and other \u201cfamily photos,\u201d at 05:22 GMT, Feb. 14, 1990, Voyager 1 powered off its cameras forever. Mission planners wanted to save its energy for the long journey ahead.<\/p>\n

In August 2012, Voyager 1 entered interstellar space; it\u2019s now the most distant human-made object ever. Voyager 2 crossed this boundary on Nov. 5, 2018.<\/p>\n

In 2020, for the 30th anniversary of the iconic image, a new version was created called \u201cPale Blue Dot Revisited,\u201d processed by JPL engineer and image processing enthusiast Kevin M. Gill with input from two of the image\u2019s original planners, Candy Hansen and William Kosmann. The updated version used modern software and techniques to revisit the well-known Voyager view, while attempting to respect the original data and intent of those who planned the images.<\/p>\n
