Seeking Starlink

The hubbub about SpaceX's Starlink satellite constellation

It’s all anyone in the space industry can talk about right now and with good reason. Starting later this year, SpaceX plans to provide low-latency internet service from low Earth orbit to people around the globe, even those in the most remote areas. To achieve such a lofty goal, Elon Musk’s space company is scheduled to launch dozens of Starlink satellites every couple of weeks. These launches create quite the viewing phenomenon in space.


To catch a glimpse of this unusual space train, you’ll have to know when and where to look. That’s where CelesTrak comes in.

Dr. T.S. Kelso, the operator of CelesTrak and a senior research astrodynamicist at AGI, has been providing free satellite positional information online for 35 years. Through CelesTrak, he is making sure that satellite data is not only readily available but also current and accurate.

Bring Starlink down to your smartphone or tablet

Using data from SpaceX, CelesTrak’s orbit visualization tool enables you to track the famous Starlink satellites in a web browser or on a mobile device. And with the same data, you can calculate Starlink viewing times with Systems Tool Kit (STK).
