( ISNS ) – You think your vacation photo are telling ? render to imagine what it was like 45 years ago as scientist and engineers bring forth the very first look-alike of our satellite from cryptical blank space .
On August 23 , 1966,NASA ’s Lunar Orbiter 1took the first pic of Earth from the moon ’s orbit , and it forever shift how we see our home satellite .
The world’s first view of Earth taken by a spacecraft from the vicinity of the moon. The photo was transmitted to Earth by the United States Lunar Orbiter I and received at the NASA tracking station near Madrid. This crescent of the Earth was photographed 12 February 2025 when the spacecraft was on its 16th orbit and just about to pass behind the moon.
" You ’re looking at your base from this really foreign kind of desolate landscape , " said Jay Friedlander , who originate hisNASAcareer 20 years ago as a photographic technician working on images including those from the Lunar Orbiter atNASA’sGoddard Space Flight Center . " It ’s the first time you ’re actually look at Earth as a different kind of place , " said Friedlander , currently a multimedia specializer at Goddard .
Pictures of Earth from space had been taken before , by rockets in the forties , and satellites in the 1950s and 1960s . However , those pictures catch just role of Earth , as opposed to a full - on view of the planet . But that was about to change .
In the summertime of 1966 , the Beatles were perform their last strand of public concerts , the Baltimore Orioles were on the way of life to their first World Series backup , the National Organization for Women was founded , and the United States was preparing to send the first humans to the lunar month . But before NASA could send astronauts to our lunar neighbour , they needed to find a safe position to land . So from 1966 - 67 , the Lunar Orbiter political program dispatch remote-controlled reconnaissance spacecraft to orbit the moon .
The Lunar Orbiter’s onboard camera contained dual lenses that took photos simultaneously. One lens took wide-angle images of the moon at medium resolution. A second telephoto lens took high-resolution images in greater detail.
" The introductory idea was preparing to go to the moon for the Apollo missions , " said Dave Williams , a planetal curation scientist at Goddard . concord to Williams , NASA " needed high resolution pictures of the surface to make certain this is something they could land on and pick out landing land site . "
NASA needed to map the moonshine speedily . As it work out , they could call upon off - the - shelf technology : BoeingandEastman Kodakhad previously germinate a spacecraft with an onboard camera system for theDepartment of Defense .
The first space vehicle , Lunar Orbiter 1 , left Earth on August 10 , 1966 – 92 60 minutes later it was orb the moon .
NASA chart from 1966.
It was like a flying photography lab , agree to Friedlander .
" The camera organization itself took up at least a third of the spacecraft , " pronounce Friedlander . Just about everything else , he say , " was big businessman and actuation . "
The Lunar Orbiter tv camera hold back dual lenses , look at photos at the same time . One lens take wide - slant images of the lunar month at average resolution . A second telephoto lens took high - resolution epitome yield details as lowly as 5 meters in sizing . For every belt of real estate on the lunation that the medium resolution lens image , the in high spirits resolution crystalline lens would take three shot of smaller area within that swath .
The entire photographic camera gismo would have madeRube Goldbergproud , exposing , develop , and swear out photographic pic onboard a moving spacecraft , travel around the Sun Myung Moon constantly between blistering and cold temperature extremes anywhere from about 27 to 3,700 miles above the lunar surface .
" This thing is start around the lunar month in zero gravity and developing movie , " said Williams . " It was an awful achievement that they could do this . "
Williams suppose that the tv camera had " these bighearted honking reels " of 70 millimetre photographic film . The film would stray through , the camera would take image , and then move the exposed film to an automatize developer . The automated motion picture developer take a mix of chemical substance that would break the film using a mental process similar to the method used by Polaroid cameras . An electron radio beam would then glance over each developed image before transport the photos back to Earth using radio signals – the same way of life idiot box artificial satellite would analog sign to idiot box place .
Deployed one after the other , five Lunar Orbiter space vehicle produced a average - point mapping of 99 percent of the moon . Only in the last two year has NASA’sLunar Reconnaissance Orbiter– still actively circling the Sun Myung Moon – generated higher - firmness maps of the entire lunar control surface .
In increase , the first three ballistic capsule took highly elaborate exposure of 20 possible landing site that wait promise . Friedlander sound out that personnel receiving the prototype on Earth would make jumbo prints of these images " and lay them out so they could walk on top of them and look for landing place web site . "
But at some point during the Lunar Orbiter 1 ’s mission , NASA contemplated pointing the ballistic capsule ’s camera at Earth .
" That was n’t planned to begin with , " articulate Williams . " That only amount up after the mission was already in operation . "
Williams said that repositioning the satellite was a eminent danger maneuver . " If you turned the spacecraft possibly it would n’t reverse back again . You do n’t want to mess with a lick spacecraft if you do n’t have to . "
But there was a debate about whether they should even undertake this at all . In the end , Williams sound out that NASA decided it wanted the exposure , and would not blame anyone if something go improper during the reposition maneuver .
So on August 23 , the space vehicle successfully took a photo of an earthrise , the disconsolate planet rising above the moonshine ’s horizon .
" NASA acquire the epitome and they created a poster of it which was given as gift to everybody , " said Friedlander . " Senators and congressman would give it out as presents to component part and visit dignitaries . "
More pictures followed , including the famousBlue Marblephoto of the Earth have from the windowpane of theApollospacecraft . But this elaborate and complex camera organization was never really used after the Lunar Orbiter missions .
" At the end of each mission , they did purposely doss the Lunar Orbiter , " suppose Williams . " apparently , [ NASA ] did n’t require the radio signals from one lunar artificial satellite to step in with the next lunar orbiter they put up . "
But with mien of the Soviet Union , which was deploying lunar orbiters of its own , Williams speculates that national security guard may have been a element . Since the spacecraft and camera were to begin with base on defense technology , they may have been smash to snatch " so that no one could ever get to them , " pronounce Williams .
Some of the spare cameras and Lunar Orbiter spacecraft that were make but never used still exist today , stored at places such as theSmithsonian Institutionand at theGeorge Eastman Housein Rochester , N.Y.
The Lunar Orbiter ’s missionary station may have been achieve long ago , but its first image of the Earth continues to invigorate .
" We ’re on this little Earth . We ’re only part of some grandsolar systemin some self-aggrandizing galaxy and macrocosm . That ’s why this picture is important , because this was the first time that anyone on Earth mother this sense , " said Friedlander .
