Why Space Exploration Matters

Bob the Science Guy examines the question by asking what it predicts, what can be measured, and whether the evidence supports it. The channel's focus is science you can observe, calculate and test for yourself.

$Live Telescope with Bob Tonight we bring out the Meade 10 inch SCT, after several days of testing it is working very well, capable of more than 4 min exposures without star trails, and is perfectly focused. We have about 2 hours of clear skies so lets see some cool stuff! I want to thank my subscribers, patreons, members and those that have supported the channel with PayPal for making this possible.

Scalars, Vectors and the Physics of Orbital Motion

$Live Telescope | Discord Chat Once again, well have a look at some satellites and the moon. Unlike last night, we are doing this with voice chat on discord. Click https://discord.gg/QwcFct7DWc to join the discord and look for us in Mt. Wolfie. We might get ambitious and try to hit some moving satellites in real time. Ive not been able to do this yet but well see if the Astronomy Gods are with us. Stop by for a chat.
