Private satellite tracking companies track both China’s and the Pentagon’s X-37BsTwo different commercial satellite tracking companies, LeoLabs and ExoAnalytics, are using their global network of radars and telescopes to track the movements of China’s X-37B mini-shuttle, dubbed Shenlong (“Divine Dragon” in English), as well as the Pentagon’s own X-37B, both of which launched recently.
LeoLabs activated its new radar system in Western Australia early last year. It’s now part of a 10-radar global network tracking the trajectories of satellites and debris so commercial operators can safely navigate the increasingly congested orbits. “We can see what’s happening in Low Earth Orbit because that’s where radar is dominant,” he explains. “But activity in higher orbits can be tracked with specialised optical telescopes. ExoAnalytics, a US commercial company, has 400 of these deployed worldwide, with 11 sites in Australia.”
LeoLabs’ radars are tracking Shenlong in its low Earth orbit. Since the U.S. X-37B is in a higher orbit, it is being monitored by ExoAnalytics.
Both these companies now provide satellite tracking services that were once the sole domain of the U.S. military. Not only does the military buy their information, so do private concerns in the U.S., since their networks track everything, not simply the two X-37Bs. Those unique craft however make for good press copy, and thus help both to sell their services to the world.
Note too that this is the first time I have seen a name attached to China’s X-37B. Previous reports never gave it a name.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

This post has me continuing to ponder if we have low observable satellites and what they would look like. Besides being hard to see. I suppose anyone reading this who knows the answer wouldn’t reply anyway. ;)
“There’s no hiding in space,” says managing director of LeoLabs Australia Terry van Haren. “It’s all observable to anyone who has the suitable sensors.” – Probably true?
John,
As an amateur observer, they look like a plane at night, only faster. Depending on how high an orbit is, and where it crosses the sky, it can take anywhere from five to ten minutes to pass over. No blinking lights. Some times it looks like they fade, disappear, comeback and repeat, but that is due to the satellite tumbling.
The ISS is very large and you can see the Dragon and Soyuz/Progress spacecraft when they are chasing to or deorbiting from the station. To find nightly passes of spacecraft, I recommend the Heavens-Above website.
Make sure to get away from city lights if possible for best viewing and bundle up.
