    Astronomy Cast Ep. 654: The Side Effects Of Clean Energy

    Astronomy Cast Ep. 654: The Side Effects Of Clean Energy by Fraser Cain & Dr. Pamela Gay To battle climate change, we’ll need to rapidly move to carbon-free sources of energy. But this technology isn’t a free lunch. They require metals, generate waste and deplete the environment. What’s the best way to balance this shift?

    Astronomy Cast Ep. 652: The Rocket Race Towards Reusability

    Astronomy Cast Ep. 652: The Rocket Race Towards Reusability by Fraser Cain & Dr. Pamela Gay Last week we talked about how single-use rocketry has changed over time, and the role it still plays in launching payloads into orbit and beyond. Today we’ll address the stainless steel elephant in the room and talk about the shift to reusability.

Well, this is it. We’re FINALLY going to talk about the James Webb Space Telescope. After decades of development, delays, budget creep, the powerful infrared observatory is at its final home at the L2 Lagrange point. Yesterday (at the time we’re recording this) we saw the first scientific images from the telescope and according to Pamela’s rules, we’re finally allowed to talk about it.
