Relating to our first conceptual objective, “I can explain how astronomical objects (sun, planets, stars) appear to move in the sky, I found this article to compliment the topic very well. Tony Flanders writes and explain the concept very well.

As we talked in class, constellations are very unique. They are something that need to be studied the proper way. There are a few things people don’t know, but it is important that we find out.Constellations are to be observed while standing outside. A tool that is being used for a long period of time and is the most popular is the planisphere, which is also called the star wheel. It shows you all the constellations visible from where your standing and shows you which stars are visible at any given date and time. Planispheres have a few negatives. Planispheres include all the stars are every season, and sometimes the stars that are visible at any given time end up in a fairly small window. Sometimes they’re also not able to show the planets as they change position.

This article tells us what constellations are about. I personally learned more about constellations then I thought I knew, and found out more about them then I thought there was. I also understand how stars are placed and looked at. Throughout the night, stars are positioned all over the sky. Only the close stars are what you can make constellations out of.


SpaceX Launch/Landing


With the conceptual objective of “I can explain how astronomical objects (sun, planets, stars) appear to move in the sky” I found this article to have a subtle but sure relevance. As we know, stars and such appear to move in the sky due to the earth’s orbit of the sun and constant rotation on it’s axis. In the article linked above, celebrates Stacey’s successful launch and landing of its first stage rocket this morning (January 14th 2017). 

The relation of the article to our conceptual objective is this, so much math and science goes into sending a rocket into orbit and then safely landing it back down onto a remote landing ship. The engineers behind this project had to take into consideration the rotation of the earth when plotting the rockets re-entry. This is because even if the rocket appeared to have gone “straight up” the planet would have rotated slightly below the rocket. In the video provided by the article, you can see the rocket using gas propulsion to adjust it’s position and better calculate a safe landing. Along with this the target that the rocket was aiming for, if viewed from the surface of earth, would appear like a fast moving star across the night sky. This relates to the conceptual objective because the satellite(s) might be stationary over earth while the earth while the earth rotates, making the satellite(s) move across the sky with the stars nightly. Unlike the stars, the satellite(s) will be a constant, whereas throughout the year, as the earth orbits the sun, the constellations will change and the satellite(s) will still be present. 

My reaction to this article would be astonished. Space exploration and the advancements that we as a species are making and plan to make in the next few years will shape our future. Along with that, the money being saved by recycling these rockets will allow more research to  be made by NASA, SpaceX, and other astronomical corporations.
