It’s Earthkam Week!

   Several times each year there is an opportunity to request pictures of the Earth to be taken by a camera on the ISS (International Space Station). This is one of those weeks, which actually started last Friday and ends this coming Saturday April 8th. Earthkam is open to educators (parents, teachers, scouts, etc.). On the mission web site there is an application form and there are lessons and activities as well as an archive of the many pictures taken by participants.
   This week I am working with students in several classes at Lee’s Summit High School, and a group of 5th grade students at Westview Elementary School tomorrow afternoon.

   Here are some of the pictures so far.

Sun Enters Scorpius-2016

   Tuesday November 22nd the Sun, in its apparent eastward motion along the ecliptic, moves out of the constellation Libra the Scales and into the constellation of Scorpius the Scorpion. This is the true or actual position of the Sun as opposed to the pseudoscience of astrology which usually has the astrological Sun one constellation ahead or east from the Astronomical Sun’s position.

   Read a little more about how astrology has the Sun incorrectly placed in a previous blog, and in another blog discussing the effects of precession.

It Was An EarthKam Week

   This past week was an EarthKam week. During the week participants are able to view the daytime orbital path for the International Space Station and request a picture to be taken of whatever the ISS happens to be passing over. This could be your hometown if the ISS happens to have an orbit that passes over where you live. The one time, so far, that there was an orbit over where I live we had completely overcast skies and rain. Nonetheless as you can see from these pictures, there is a lot of the Earth to see from the perspective of the International Space Station.
    Click on any picture to see it, or any of the rest of the pictures larger. The picture may also be viewed at its full size, which for some pictures will show an amazing amount of detail. If you are familiar with Tucson Arizona look at the picture labeled tanque verde and speedway.

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.

EarthKam Week Wrap Up

This past week I visited and worked with students at 3 schools in the Lee’s Summit School District as we participated in the Sally Ride EarthKam Mission.
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!

Here are some of the pictures we received from the International Space Station. These have been cropped to a smaller size and edited using Photoshop.
Here is a link to the full size pictures (4312×2868).
Here are some follow-up activities:
Where in the World? (Student) (what to do with an image-what is it of)
Where in the World (Teacher)
Earth Features Seen From Space
Cloud Patterns

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.

March 2015 Equinox and Solar Eclipse

   Friday March 20th is an equinox day. This means that for those in the northern hemisphere winter is ending and spring has ‘sprung’ (starts). For our counterparts south of the equator summer is ending and fall is beginning. From a geographical perspective we would describe the Sun as being over the Earth’s equator, and as this graphic shows there would be an equal amount of daylight and night on our planet as a result.
    At mid-day on the equator the sun is directly overhead and from that latitude you have no shadow, just a ‘blob-like’ shadow at your feet as this picture of my feet taken at mid-day in Quito Ecuador shows.

    Regardless of your hemispheric preference get outside and cast a shadow!

seasons-ani  Northern hemisphere spring officially (well at least astronomically) begins at 22:45 UT (4:45 pm CST) on the 20th when the Sun reaches the celestial coordinates of 0 hours and 0 degrees as it moves northward along the ecliptic crossing the celestial equator. At this location the Sun is within the constellation of Pisces the Fishes and not just entering Aries the Ram as the pseudoscience of astrology would have you believe.

    To learn more about the celestial coordinates click here to read a previous post about seasons and the equinox.

   The time of this equinox is about 13 hours after a new Moon phase and a solar eclipse. This picture shows the shadow of the Moon cast on the Earth during a solar eclipse as seen from the International Space Station.

   Here is a short series of hourly pictures taken during the day on the September equinox on the equator in Quito Ecuador at Collegio Menor San Francisco de Quito, a private school that I visited and did the SunShIP project with (Sun Shadow Investigation Project).
