Ham Radio ISS – How to Call Space Station Astronauts

It’s a great story—but here’s what NASA told us.

Well written news report.  News reports suggested  a ham radio operator in India  contacted the SpaceX Dragon crew on board Dragon (one of the astronauts is a ham radio operator). The story notes many hams (including me) have, in fact contacted ISS (mailbox/APRS) or crew (two of the crew on board right now are ham radio operators) and that this is fairly common.

In this case it appears the original ham radio operator in India may have gotten confused with a press conference link.

Space: SpaceX, OneWeb and Amazon may be ruining night sky

SpaceX may launch 30,000 more low altitude satellites added to the 12,000 it already plans to launch. OneWeb is launching 900 satellites  and Amazon is planning  over 3,000 satellites. There are predictions that any given moment, over 100 satellites will be visible crossing overhead, no matter where you may live.

Astronomers propose global network of low cost receivers or cell phones #Astronomy #Radio

Astronomers have proposed a global network of radio receivers to search for fast radio bursts. Their concept would use either smart phones and an app listening to a portion of the cellular spectrum allocation, or a low cost device that could be plugged in to the USB port of personal computers.
