There are more than 2,250 satellites orbiting the Earth right now . But that nonobjective telephone number did n’t train me for the stupor of look on a Soviet - era rocket body whipping over my house in real - time .
Then I watched an elderly Russian intelligence operation planet glide over Seattle . A NOAA weather satellite slid by Newfoundland and the ISS authorize over Sumatra , while China ’s Tiangong man station run over the Mississippi River Delta . I was usingLine of Sight , an extraordinary map created by Patricio Gonzalez , an creative person and engineer at the assailable - reference map startup Mapzen .
Satellites in ambit are moving at roughly 17,000 miles per hour , intend they hap over your city in a thing of minute , but that ’s still enough meter to espy them , if you know where to depend — which has always been a challenge … until now . Using metadata about the chiliad of orb satellite is available through reference likeSatNOGS , Gonzalez ’s mathematical function monitors satellites as they criss - cross the world , allowing you to track specific space vehicle or get wind when and where you should look to see those pass over your mansion .
When I first opened up the mathematical function , I navigated to Lake Michigan , and watched as a planet passed over Chicago , where I live .
A straightaway hunting of the name revealed the SL-16 isactually a rocket body progress by the Soviet blank programin the 1980s — essentially , space junk . There are in reality 17 of them in field . It was part of a failed plan “ to take over manned starship launching from Soyuz , but these program were abandon after the fall of the Soviet Union . ”
If it had been nighttime , I would have known where to look for the rocket body , which is about as bright as stars in the big Plough , allot toSpace Weather .
The data Gonzalez used to create this map is readily usable , and it ’s not as though orbiter - watching is a new idea . But for tiro , Line of Sight is a magical and visceral illustration of the spacecraft that make the innovative man possible – turning them from an abstract idea into a blink brightness level , passing above your backyard . Go check it outhere .
