DIY Space: The Sentinel Mission

This particular DIY Space isn’t so much about building a space project as it is about being involved with one.  In this case, the involvement looks to be your potential donation of money to the Sentinel Mission.  But your money could potentially help save millions of people–literally. There have been some questions lately as to […]

Why space matters: HEO Satellite Operations, Part 1–You’ve Never Kepled?

In previous lessons you’ve learned about the Low Earth Orbit (LEO) and the Geosynchronous Orbit (GEO).  There are pros and cons in using each orbit.  Generally for satellites in LEO orbit, particularly imagery satellites like those owned by DigitalGlobe and SkyBox, the closer the satellites are to the Earth, the more detail of the objects […]

Why Space Matters: GEO Satellite operations, Part 4–Communicate

“…You gotta reach out – Reach out and touch someone…” The last lesson showed how a geosynchronous (GEO) satellite can essentially “hover” over a particular area of the Earth.  Almost as if a physical rigid connection keeps them moving together.  This is because the GEO satellite’s orbit matches the speed of the Earth’s rotation, giving […]

Why Space Matters: GEO Satellite operations, Part 3–Revolution Earth

“Endless Distance, Wildlife and Stars, Blanket the Night…” The last lesson was about Field of View (FOV) and Field of Regard (FOR).  It was intended to help with understanding the next few lessons regarding satellites in geosynchronous orbit (GEO).  All mentions of GEO on this blog, unless otherwise stated, refer to a particular type of […]

Why Space Matters: GEO Satellite operations, Part 2–FOV/FOR-it things

In the first lesson, you learned (if you didn’t already know) a spacecraft in geosynchronous orbit is very far away from the Earth—a little over 26,000 miles. Before going any further, an explanation of Field of Regard (FOR) versus Field of View (FOV) is in order since we will initially be talking about weather imagery satellites.  […]
