The Serenity satellite is a CubeSat that will provide low-cost opportunities to test educational experiments in space. Serenity carries a suite of data sensors and a camera that will be sending data back to Earth.

Serenity is licensed as an amateur radio broadcaster, which allows it to communicate with radios on the ground. See below for lessons on building an inexpensive radio and tracking system. Anyone with a ham radio can “talk” to Serenity. Ground stations connecting with the satellite during its orbital period will collect and share the data and pictures transmitted back to Earth.

Launch and Orbit Details

Serenity launched on Sept. 2, 2021 at 9:59 pm ET but was destroyed when the rocket experienced an anomaly.

A successor to Serenity is now in the works.


How to Communicate with Serenity

The best option to communicate with Serenity is to connect with a local Amateur radio club. They may have the equipment already set up to track satellites. If they do not, they will be able to assist you in finding one that does.

The following lesson plans will help you locate Serenity and send commands to receive packets of information containing experiment data and satellite telemetry:

  • Using a Software-Defined Radio system
    • Lesson 1: Setting up a Listening Station
    • Lesson 2: Tracking Satellites
    • Lesson 3: Communicating with Serenity (Coming Soon)
  • Serenity’s Contact Info
    • NORAD ID: TBD
    • Call Sign: WU2M
    • Public Channel: Mode 2 (M2)
    • Frequency range: 437.1

Connecting to Serenity

Connecting to Serenity is similar to making a phone call. The format follows Satellite, Station, Mode, Command as shown below:

  • Satellite Call Sign: WU2M
  • Operators call Sign: (the radio you are trying to connect from)
  • Mode: M2 (Public mode available)
  • Command Choice: Status, List, Rad

Each command choice asks for a specific information packet to be sent back.

  • Status: sends back the current health and location of the satellite.
  • List: sends back a list of the stations that have contacted the satellite in the past 7 days.
  • Rad: sends back a data file of dosimeter readings from the radiation experiment.

We can download one photo per day from the satellite while in orbit. We’ll publish the photos here on our website. Take your best shot!
