UCS Satellite DB

The UCS Satellite Database has been tracking active satellites in Earth orbit since 2005. It's free, updated regularly and available at:

104! That is A LOT of #satellites. Per our DB, will increase the total number of operating satellites by around 7%. @planetlabs @ISILaunch https://t.co/HfVe3Z1Gct

[Jonathan McDowell @planet4589]

ISRO reports all 104 satellites have been deployed!

[UCS Satellite DB @UCSSatDB]

It will reportedly include sats fm Israel, Kazakhstan, The Netherlands, Switzerland, United Arab Emirates & 96 from the US. Yikes!

[UCS Satellite DB @UCSSatDB]

Russia once launched 39 nano-sats in one go, but India's will be nearly three times as many. The report says the launch is tomorrow, Feb. 15

[UCS Satellite DB @UCSSatDB]

An upcoming record launch will keep us more busy: 104 nano-satellites in one go: https://t.co/Ca3cPGUp6x #lotsofsats #somanysats

Apologies for the break from tweeting, been a lot going on and still working to finish latest update to the satellite DB.

[UCS Satellite DB @UCSSatDB]

Possibly true, @AFSpace, but you've got MilStars operating a lot longer that the 10 years listed in the graphic! @ulalaunch #longlasting https://t.co/62WNh0mrrU

[United States Space Force @USSpaceForce]

DYK? Satellites last 25 years. Thx for the neat graphic and all your support, @ulalaunch!

[UCS Satellite DB @UCSSatDB]

Our favorite satellite comes up with amazing data. We need more scientists to dig into to these deep space questions! #sciencematters https://t.co/LltVuYQUcV

Hubble image puzzles scientists with this view into a luminous galactic core of a black hole: https://t.co/YSfhVAkze6

[UCS Satellite DB @UCSSatDB]

@ceoworld Thanks for the tweet. Note that later this month we will be updating that data and producing a new graphic. #we💙satellites

[CEOWORLD magazine @ceoworld]

Total number of operating satellites: 1,419

US 576
China 181
Russia 140
Other: 522 - @UCSSatDB

[UCS Satellite DB @UCSSatDB]

That is 13 times the speed that GOES 3 provided over its long service to the South Pole https://t.co/nXYKfPuzq6

[UCS Satellite DB @UCSSatDB]

DSCS III B7 sat that replaced GOES 3 for Antarctic comms does so 3.5 hrs/day at speeds up to 30 megabits/sec https://t.co/nXYKfPuzq6

[UCS Satellite DB @UCSSatDB]

Lightest satellites in our DB? Hard to say - we've got 30+ under 1 kg & more coming, given the explosion in cube/nanosats. #smallisbeautiful

[UCS Satellite DB @UCSSatDB]

Heaviest #satellites in our DB? Three massive US NRO recon ("spy") KH sats, at 18,000 kgs each (launch weight), each the size of a bus.

[UCS Satellite DB @UCSSatDB]

Interesting, interesting - aggressive timelines, unclear financing, but looks to be talented people - worth watching https://t.co/uBkCgJbVki

A company you’ve never heard of plans to build the world’s first private #SpaceStation

The new #satellites are here! The new #satellites are here! (HT Steve Martin.) Go @Arianespace Go @sslmda! (Go @SpaceflightIns!) https://t.co/vS5yG1s0MB

[SpaceFlight Insider @SpaceflightIns]

It's launch day for #Ariane5 #VA234 carrying @sslmda-built #StarOneD1 & #JCSAT15 satellites https://t.co/FNbDEJRJnm Img Credit: @Arianespace

[UCS Satellite DB @UCSSatDB]

If I were a #satellite, I'd want to be in a highly elliptical orbit. LEO & GEO just seem so boring. #TuesdayTip

[UCS Satellite DB @UCSSatDB]

Thundering into space, another #satellite for the database. Looks like we won't be releasing the new version until the new year. https://t.co/NTlcytLvTp

Wow, a stunning image. Way to go, @Space_Station (and thanks for using "Uluru," @NASAEarth - good to know.) #ancientnames #geologyrocks https://t.co/bqdhpoY3Ak

Last day to order from our store and get it by December 25! https://t.co/YmemVUxtOG #scienceswag

Hey @ArmsControlWonk @geo4nonpro @mhanham, have y'all looked at @BlackSky_Inc yet? Imagery warehouse option? https://t.co/ozJaVIlPa9
