Asteroids—Space Colonies 53 min.

Recent discoveries of water at the moon’s poles and on Mars have encouraged public institutions, such as NASA and the European Space Agency, as well as private companies, like SpaceX, to lead projects that will let us settle in these harsh, distant environments in the near future. This episode explores the challenges of setting up an orbital space colony or a settlement on an asteroid, such as the...

Mars—Space Colonies 54 min.

The Red Planet, with the most similar environment to earth in our entire solar system, is a third alternative being explored for colonization. The discovery of ice on its surface has excited and encouraged many space scientists, despite the many challenges. The distance of Mars from the earth makes a space flight dangerous and possibly lethal for astronauts, while the lack of atmosphere would make...

The Moon—Space Colonies 53 min.

The moon’s proximity to earth, as well as the discovery of water there, have placed this natural satellite front and center as a viable location for our first interstellar colony. In fact, the director of the European Space Agency has already outlined their plans for a “moon village”, intended not only for scientific and technological research, but also for activities based on exploiting resources...

Space Colonies 156 min.

It’s possible that in the near future the earth could become uninhabitable due to climate change or overpopulation. As a result, we may need to move to an orbital space colony or to another place like the moon or Mars. Present-day technology means this is not just something from a science fiction movie or book, but possibly a reality within this century. This series explores the challenges of sett...

Shedding Light on Energy: Episode 2—Measuring Energy 35 min.

In this program, we introduce the “joule”, the unit for energy. We then look at how much energy is stored in different foods by comparing apples and oranges (normally a no-no) and we discuss how much energy we need to do certain things including nothing much at all. We then explore the concept of energy balance and reveal the two simple rules for weight loss. That’s right, there are only two!

Shedding Light on Energy: Episode 3—Energy Efficiency 31 min.

In this program, we introduce students to the concept of efficiency, which is a measure of how much useful energy you get out of something compared to the amount of energy that you put into it. We answer a bunch of questions including: How much light energy do we get out of light globes compared to the amount of electrical energy that goes into them? Hint: it’s not much; they should be called heat...
