In the second installment of our Elements series (not like Olivia forgot or anything), we’re taking off into the air. Elise tells us about Starlink, a project of Elon Musk’s SpaceX, and how the race for space internet might come with a massive sacrifice. Also, space garbage? Then, Olivia tells the story of the relatively new ‘flygskam’ movement, all the industry executives pressed by Greta Thunberg, and how flight free travel could be the wave of the future. We talk about what we should (and shouldn’t) sacrifice for the greater good, billionaire Twitter feuds, and the connection between wealth and carbon emissions.
First we recap a bit of last week’s mammoth vegan episode, and Elise mentions her Imperfect Foods subscription (Click here if you want to join via her referral code, but obv #notsponsored).
Story #1: SpaceX’s Starlink Internet (Elise)
Starlink satellites are visible through telescopes and to the naked eye, in both cases obscuring our precious view of the cosmos. These images were taken before the introduction of VisorSat.

This simulation by astronomer Michael Vlasov shows what a dark night sky would look like with 12,000 Starlink satellites in Earth’s orbit. Note that this simulation was created pre-VisorSat, so satellites launched today are currently only 31% as bright as the ones depicted in the video. But Elon’s goal is to launch over 40,000 of them.
I don’t want to overload you with pictures of the sky, but I’m kind of overwhelmed by them and need to share. For example:
If you had no idea what Elise was saying when she was explaining why satellites reflect light from the sun onto Earth, maybe this diagram from SpaceX will help.
If you are interested in getting involved in this, there’s a NASA Satellite Streak Watcher project spearheaded by astronomer Sten Odenwald where you can take photos of the streaks left by satellites with your smartphone to help collect data about how they are affecting our night sky and how that changes over time.
You can find out where satellites are passing by by going to Heavens-Above.com, changing your observation location, and then clicking to the Live Sky View page. I believe the goal here is to capture the satellites as they streak over our most beloved constellations, so once you locate your sky, you can watch the satellites move through and time things out accordingly. If there are no satellites in your area and you want to find where they are, you can search through different locations. Remember these satellites are most visible at dusk and dawn, so that’s the best time to take pictures!
If you happen to take any satellite photos, in addition to submitting them, please send them to us too at email@example.com!
BREAKING NEWS: There’s a bit of an update on the SpaceX regulations front. On Tuesday February 2nd, aka the day after this episode was recorded, a SpaceX Starship SN9 exploded after launch. This comes after, SpaceX had “sought a waiver to exceed the maximum public risk allowed by federal safety regulations,” and Elon Musk had publicly criticized the Federal Aviation Administration for hindering his progress with their regulations. While there was no one on the rocket, these are the ships Musk hopes to send people to Mars in someday. While in this episode SpaceX takes action in response to the outrage of the scientific community, the happenings of February 2nd certainly bring up questions as to their commitment to public safety and wellbeing when there is progress (and profit) to be made.

Here is the technical to-do list from Stay Grounded:
1. Non-CO2 impacts have to be fully accounted for by the industry, by institutions and governmental bodies and by UNFCCC within the framework of the Paris Agreement.Stay Grounded
2. Known measures to mitigate non-CO2 impacts, such as contrail avoidance and the adoption of lean-burn low NOx engines, must be pursued immediately in addition to CO2 mitigation.
3. Research and development of operational and technological improvements, which give the same importance to the reduction of non-CO2 impacts as to CO2 reduction, must be intensified and funded.
4. Air traffic must not be allowed to return to pre-Covid-levels. Accordingly, bailouts, subsidies, tax exemptions, and the construction and expansion of airports must cease. Governmental measures for a deep, sustained reduction of flights and for substituting alternatives like rail travel and renewably-powered ships must be quickly implemented.
