Yuri’s Night 2020

yuri   April 12th 1961 Cosmonaut Yuri Gagarin became the first human to leave the surface of the Earth and orbit our planet. Coincidentally 20 years later, on the same date in 1981 the United States launched its first space shuttle, the Columbia.
   However April 12th is a date for celebrating the accomplishments of the Russian space program and the cosmonaut who became the first human to orbit the Earth. So, on April 12th people around the world will take part in local events in what is known as Yuri’s Night. Use the link to the Yuri’s Night web site to learn more about this event and to see if there is a Yuri’s Night event in your area.

         Yuri’s Night to Host Global Webcast on April 11, 2020

Due to health concerns, and in cooperation with local health officials, the large Yuri’s Night parties planned in Los Angeles, CA, at the Kennedy Space Center in FL, and in London have been cancelled. This is the same of many events around the world this year. Although some events may be rescheduled for later in the year, our dedicated crew of volunteers is working hard to develop at Global Webcast for April 11 so that we can all celebrate together! This online event will be free and available to anyone around the globe. It will be an opportunity for people around the world to connect with each other while avoiding crowds. Join us on April 11! Details and more information will be available at

         Dark Matter
yuri   9 years ago during the 50th anniversary I had an opportunity to work with a group of musicians (Dark Matter) in producing a series of videos about the solar system and our home planet that were then projected as full-dome videos on a Planetarium dome ceiling. Accompanying the videos were two musicians playing their respective instruments (Flute and Clarinet) along with electronic notes, live sampling of their music, and sounds of the interior of a spacecraft. Below is a version of that performance that was entered into a worldwide contest – placed in the top five by the way.
   Please excuse the quality of the video graphics – a result of my video abilities and state of video editing capabilities ‘way back then’.

A Disco Ball In Orbit!

   The Humanity Star satellite was launched from New Zealand earlier this month and has an orbital life expectancy of around 9 months – (spoiler alert!!) meaning it’s coming back down!
   The satellite is a 1-meter diameter geodesic dome shape made of highly reflective materials. While in orbit the Humanity Star will spin and reflect enough sunlight making it bright enough to be seen which means this could prove to be perhaps as fun as tracking ISS and Hubble. Right now the satellite is only visible from latitudes greater than 46 degrees north or south but the orbit will gradually change making it visible from all latitudes.
   The web site has an interactive tracking map.
      “The Humanity Star was created by Rocket Lab Founder and CEO Peter Beck. It was born of the desire to encourage people to consider their place in the universe and reflect on what’s important in their own lives and the lives of humanity as a species.”

August Moon at Ascending Node – and Oh Yeah, A Total Solar Eclipse!

   Monday August 21st the new Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   On August 21st the new Moon will be crossing the plane of the ecliptic at 10:34 UT (5:34 am CDT) within the constellation Leo the Lion. 8 hours later, at 18:30 UT (1:30 pm CDT), the Moon will reach new phase. This close timing between the new Moon phase and a node crossing means only one thing – eclipse!!

   My eclipse viewing area will be at an Elementary School in the North Kansas City School District. From that location totality will be approximately 80 seconds. This short video showing totality for 80 seconds, was clipped and edited from a video shot during the November 2012 total solar eclipse viewed from Australia.

   Read a bit more about this eclipse from a previous post.

      Does our Moon actually go around the Earth as many graphics show? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

ISS Last Night

   Last evening was my first opportunity to see the ISS in at least a month so I quickly set up my camera aiming it toward Venus and Mars. However my aim was off by quite a bit so I hurriedly readjusted the camera, 3 times, to capture these pictures. All were taken with ISO 800; F5; 18mm; 2.5 second. Pictures were stacked, merged, using Starstax.

ISS This Evening

   Despite a temperature of 6oF and standing in a couple of inches of snow it was worth it as Venus and Mars shined brightly over my neighbor’s laser light show and I waited patiently for an ISS orbit over my home this evening. This orbit had the International Space Station rising in the northwest and setting in the southeast in a 6-minute visibility that took it nearly to the zenith with its maximum altitude of 85o above the horizon. It’s orbital track had the ISS pass along one side of the ‘Summer Triangle’, the stars Vega and Deneb. As it nears the zenith the ISS will pass very close to the star Alpheratz, the upper left corner star of the asterism “Square of Pegasus”. Alpheratz is actually a star in the constellation of Andromeda the Princess, but it it is commonly used to complete the ‘Square of Pegasus” asterism.

   Camera settings were 18mm; ISO 800; F6.0; 3.2 sec. Pictures stacked using StarStaX. StarStaX is available as Freeware for Mac OS X, Windows and Linux.

NSTA @ Nashville


   I’m in Nashville Tennessee for the next several days at the NSTA national conference. Planets and stars will still be in the skies but not as easy to see from downtown Nashville as it is where I live. On the morning of April 1st the waning waning crescent Moon will be within a few degrees from Dwarf Planet Pluto. Too dim to be seen without a large telescope it is, nonetheless, a neat idea that when you look toward the Moon you are also looking in the direction of Pluto. It’s out there!
   And here is a sequence of graphics showing the pre-sunrise morning sky at 5:30 am EDT for each day during the conference, and one night view on April 1st showing Jupiter. Both Pluto and the Moon are located just above and to the left from the handle of the teapot asterism for Sagittarius the Archer.

It’s EarthKam Week

   This week I am privileged to be able to once again take part in the Sally Ride EarthKam Mission with students in the Lee’s Summit School District and Aerospace students at the Center for Advanced Placement Studies (CAPS) in the Blue Valley KS School District.
earthkam-ani    What is EarthKam? In short it is an opportunity for students to request images of the Earth’s surface to be taken by a camera on the International Space Station. The previous time I participated with the program was last January and during that week the daytime orbits we could request images from were all from the equator and southward. We got some great pictures of mountains and islands, and of course clouds!
