Starlink is a satellite constellation being constructed by SpaceX[1][2] to provide satellite Internet access.[3][4] The constellation will consist of thousands of mass-produced small satellites in low Earth orbit (LEO), working in combination with ground transceivers. SpaceX also plans to sell some of the satellites for military,[5] scientific, or exploratory purposes.[6]
Concerns have been raised about the long-term danger of space debris resulting from placing thousands of satellites in orbits above 600 km (370 mi)[7][8] and a possible impact on astronomy,[9] although the Starlink satellites orbit at 550 km (340 mi)[10] and SpaceX is reportedly attempting to solve the latter issue. On Starlink 2, one of the satellites has an experimental coating to make it less reflective, and thus impact ground-based astronomical observations less.[11]
The total cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be about US$10 billion.[12] Product development began in 2015, with the first two prototype test-flight satellites launched in February 2018. A second set of test satellites and the first large deployment of a piece of the constellation occurred on May 24, 2019 UTC when the first 60 operational satellites were launched.[1][13] The SpaceX satellite development facility in Redmond, Washington, houses the Starlink research, development, manufacturing, and on-orbit control operations.
As of April 22, 2020 – with 417 satellites[14] of the constellation in orbit[15] – SpaceX is targeting service in the Northern U.S. and Canada by late 2020. SpaceX is launching 60 satellites at a time, aiming to deploy 1,584 of the 250 kg (550 lb) spacecraft to provide near-global service by late 2021 or 2022.[16] However, these are only internal projections and not set dates.

Wow. That’s a lot of satellites.

Bookmarked! Thanks for posting this knave ~ This is by far the most accessible website for satellites - you don't need a certificate in fortran to navigate. -Bob |

I saw something about that on Facebook. Pretty cool although that's a lot of stuff in orbit around the earth.

Hmm...I might have seen this a few evenings ago. Shortly after sunset in the southwestern sky. A thin line of what appeared to be closely spaced dots.
Nah...on 2nd thought...it was probably an alien spacecraft...

We saw them come through last night. They were not super bright although we did have a very bright moon, which would dim the star viewing.
They came across the Big Dipper, spaced about 1 dipper length apart, and about every 15 or 20 seconds. Very interesting.
