Over 20 years ago, Iridium launched a constellation of 66 satellites into space, paving the way for the future of satellite communications. From Earth, unexpected reminders of the constellation’s presence appeared – Iridium Flares, a streak of light in the sky caused by sunlight reflecting off the main mission antenna of an Iridium® satellite. These Flares, which can be seen anywhere in the world, have been likened to shooting stars. As we conduct the largest constellation replacement program in history, known as Iridium® NEXT, our original Block 1 satellites are being deorbited and taking their Iridium Flares with them. Click here to read more about #flarewell.

Join us in saying #flarewell to our Block 1 satellites and help us welcome the future of Iridium NEXT!

How to Catch a Flare

There are many websites and apps available to help you calculate exactly when a Flare will be visible in your area.

  1. Determine your GPS latitude and longitude coordinates.
  2. Use a website or app to input your coordinates to determine the time and location of an Iridium Flare in your area.
  3. Double-check the prediction shortly before observing, as Flare forecasts can change.
  4. Go outside at least a couple of minutes prior to the time listed on the correct date. (Note: If the sky is not clear, you likely won’t be able to see the Flare.)
  5. Look in the direction of the Flare forecast.
  6. Don’t forget to snap a pic for Instagram or Twitter and tag #flarewell!

You captured a lot of tumbling satellites @Spicey_Spiney: Any dotted lines among them for Iridiums?

🛰️🛰️🛰️🛰️🛰️ 5 great pack of new flarew available at #catchtheiridium database (+1124)! What a top quality captures! Thanks @Spicey_Spiney🇬🇧 (SV38 in milkyway) @AdamDeltaV🇺🇸 (SV61) Robert Williams🇺🇸 (SV97) @iramollay 🇦🇹 (SV97) & @TelLekatsas 🇦🇺 (SV24) #flarewell #iridiumflare

#flarewell 看了几个帖子才知道,前辈们看铱星的乐趣是自己计算过境时间,然后到了那个时间对照自己算的对不对。听起来真有意思啊

Our Commitment to Space

As a leader in the satellite communications industry and operator of the world’s preeminent Low-Earth Orbit (LEO) satellite constellation, Iridium is committed to both ensuring the sustainability of LEO in the future and serving as the leading example of what it means to be a responsible steward of space.

For these reasons, we are carefully deorbiting our legacy constellation of Block 1 satellites as part of the Iridium NEXT satellite replacement program. When approaching retirement, each Block 1 satellite is put on an ‘end-of-life’ plan that carefully choreographs the time and location of its decommissioning, leading to its eventual disintegration in Earth’s atmosphere. By doing so, we maintain the highest standards of space debris mitigation and help ensure the sustainability of space for the future.
