The Deep Space Exploration Society is a Colorado based nonprofit organization dedicated to practical astronomy and space science education for students, the general public, and society members.

Our major project is restoring and operating a 60-foot dish antenna for radio astronomy and amateur radio experimenting.  The site is located in Kiowa County, in Colorado. Since 2009 our volunteer members have been working hard to restore and modernize the antenna and its support facilities.

We accomplished our first successful scientific measurements of galactic neutral hydrogen (HI) at 1.4 GHz in August 2016.  Since 2018 we have been undertaking systematic neutral hydrogen measurements of our Milky Way galaxy:

  • We are surveying brighter individual astronomical radio sources in order to measure the capabilities of our equipment, to see what we can see, and to develop a catalog of objects we can use for reference calibration.
  • We systematically measured the Doppler shifts of the hydrogen along the Milky Way galactic plane, in order to derive the rotation rates of the galactic disc. We  also used these measurements to measure the speed of the Earth in its orbit around the Sun.
  • We are working now on detecting and measuring pulsars.
  • We are using SpectraCyber and SDR receivers.
  • We are publishing our work in  amateur radio astronomy journals.

A significant technical accomplishment is the development of computer-based control systems for accurately pointing the dish antenna to celestial coordinates.

We are also doing other radio astronomy experiments, including:

  • Joint observations for the Search for Extraterrestrial Intelligence (SETI) with the 40-foot radio telescope dish antenna at the Greenbank Observatory in West Virginia
  • Radio science observations of Jupiter and its moon Io
  • Solar Wind Observations using the Sudden Ionospheric Disturbance Monitor (SID) at Very Low Frequencies (VLF)
  • Meteor Scatter

Our Amateur Radio experimenting work includes:

  • Engineering design, building, and coding
  • EME Moon Bounce (planned)
  • Troposheric Scatter (planned)

We host an Open House at our radio astronomy antenna site for the local communities each August, during the Perseid Meteor Shower.

Our Website

This is our site for sharing information about the science and engineering support at the Deep Space Exploration Society.

We are in the process of rebuilding our site.  Please continue to check back.

  • We will continue to post news about our progress restoring and modernizing our radio telescope site.  Much work has been accomplished, and we are now starting to become operational.
  • We will develop and post more information about our science.  That will include:
    • Educational material about the science and data analysis methods.
    • Science results.
    • Provisions for you to participate in analyzing the science data.
    • Reports about our presentations at science and engineering conferences.
  • We will post announcements about our regularly scheduled monthly science and engineering meetings.  Plus we will post announcements of our public outreach and educational events.


Membership in DSES runs from the start of each calendar year.    Dues are $50 / year for voting members and $20 / year for non-voting members.
