How I observed the International Space Station (ISS) transit the Moon with a Unistellar eVscope! \u00a0<\/em><\/h3>\n

Space station! Read it, hear it, or think it, and my mind is immediately transported to the scene in Star Wars: Episode IV \u2013 A New Hope<\/em> when Obi-Wan Kenobi, Luke Skywalker, Chewbacca, and Han Solo find the Death Star and Obi-Wan says \u201cthat\u2019s no moon, it\u2019s a space station\u201d (Lucas 1977). On Saturday morning, November 16, at 3:43 am PDT in Pioneer Park in Woodland, California, I saw both a space station and a moon with a robotic telescope that fits in a backpack!<\/p>\n

The International Space Station (a.k.a. the ISS) is one of the greatest technological achievements of human creation. The football field sized space station is a scientific laboratory collaborative with countries around the world researching biology and biotechnology, Earth and space science, education, human space travel, physics, and technology. It travels at 17,500 miles per hour and 240 miles above the surface of the Earth completing an orbit every 90 minutes, 16 times a day!<\/p>\n

Although it would be nice to take the Millennium Falcon for a spin and find the space station, I\u2019m pretty sure that Disneyland\u2019s Galaxy\u2019s Edge keeps their Falcon guarded by the finest of the First Order. I am still hoping on taking the Falcon for a joyride one day, but in the meantime, there are other more realistic opportunities of finding space stations.<\/p>\n

Finding the Space Station<\/h3>\n

NASA\u2019s website, Spot the Station<\/em><\/a>, shows you how to track the ISS and even find out when you can see it fly over your location. Additionally, there are several computer and phone applications that will notify you when and where to look to see the ISS fly overhead (e.g. SkySafari<\/em>). This is best observed at night with your naked eye. The ISS will appear as a fast-moving bright dot across the sky. I\u2019ve witnessed this several times and it is always exciting, however, what I experienced from Pioneer Park was much cooler, but also seemingly much harder and rarer to observe.<\/p>\n

There is another website to track the ISS, but it is not just for any typical kind of flyover. Sometimes, when the conditions and geometry are just right, an observer can catch the ISS transiting across the Moon or Sun!\u00a0FYI, a transit is when a smaller object passes in front of a larger object from an observer\u2019s point of view.<\/em> <\/strong>Bartosz Wojczy\u0144ski\u2019s site, ISS Transit Finder<\/em><\/a>, allows you to input any Earthly coordinates to find out when and where the closest ISS transit to your location occurs across the Moon or Sun.<\/p>\n

The Unistellar eVscope<\/h3>\n

As a part of my PhD research, I\u2019ve recently acquired a new type of robotic telescope, the Unistellar eVscope<\/a>. The eVscope is an autonomous 4.5\u201d Newtonian-like telescope controlled via a dedicated smartphone application that fits in a backpack. It uses a CMOS light detection sensor, onboard computer, and its proprietary Enhanced Vision technology to capture more light than your average amateur optical telescope. One of my advisors, Franck Marchis, astronomer at the SETI (Search for Extraterrestrial Intelligence) Institute, encouraged me to try and capture the ISS transiting the Moon to test its capabilities and I was successful!<\/p>\n

Planning my ISS Moon Transit Observation<\/h3>\n

To plan the ISS observation, I used Wojczy\u0144sky\u2019s ISS Transit Finder site and discovered that the ISS was set to transit a waning gibbous Moon near Sacramento, California at 3:43:14 am PDT on Saturday, 16 November 2019. Viewing the ISS transit the Moon is similar to viewing a total solar eclipse in that you need to be in a special narrow band of area in order to observe it.<\/p>\n

After researching locations in the visibility path, I discovered that the transit would be visible from Pioneer Park in Woodland, California. Since the time of the event was after the closing hours of the park, I contacted the City of Woodland\u2019s Parks Supervisor to get permission to be there afterhours. Westley and the Community Services Department graciously gave me permission, as well as contacted the Woodland Police Department to inform them that I was allowed to use the park for my observation. Officers Ted and Dalbinder even stopped by briefly during my observation to say hi and look through the eVscope.<\/p>\n

MUSE’s Simulation Theory and Capturing the ISS Moon Transit<\/h3>\n

I generally like to plan my observations with some good music to play in my wireless headset, so I downloaded an album from one of my favorite bands\u2014the sci-fi 80s inspired Simulation Theory<\/em> by MUSE<\/a>. With my telescope set up in the north west area of the park, I used the eVscope\u2019s software application to find and track the Moon while also enjoying the perfect synth accompanied soundtrack from MUSE while I waited anxiously for the predicted transit at 3:43:14 am.<\/p>\n

The Unistellar app not only controls the telescope, but also provides live views and allows one to download images from an observation. The ISS transit was predicted to only last 0.56 seconds so in order to not miss the event, I decided to use my iPhone\u2019s native screen recording tool, Screen Recording<\/em>, which is found in the iPhone\u2019s Control Center.<\/p>\n

About two minutes before the predicted transit time, I pressed record on my iPhone and crossed my fingers that I would catch the transit. Just as predicted and shortly after my clock turned to 3:43 am, I saw a small shadow speed across the disk of the Moon! \u201cWow!\u201d, I said to myself. I couldn\u2019t believe my eyes. I got it! After I let my phone record the live event for a bit more time, I stopped the recording and opened the saved video from my photo roll to check that what I had just witnessed wasn\u2019t my imagination playing tricks on me.<\/p>\n

Out of the Gloom, a\u00a0<\/em>MUSE Inspired ISS Transit Video<\/h3>\n

After successfully capturing the ISS Moon transit with the eVscope, I wanted to make a simple, dramatic, and artistic video of the event. I knew the music of MUSE would be a perfect soundtrack to this cosmic event and their digital team very graciously gave me permission to use their song, The Void<\/em>, in the video. I used the raw iPhone screen recording of the eVscope Unistellar app in Adobe Premiere Pro to make my video. MUSE retweeted a post of mine on Twitter<\/a> with the uploaded video to their followers around the world and it was very well received!<\/p>\n
