Space Policy Edition: Shutdown
In a government shutdown seemingly without end, we bring you two stories from individuals directly impacted by the crisis. NASA scientist and union representative Lee Stone discusses the missed paychecks, loss of science, and lasting negative consequences to the public sector scientific workforce. Rob Hoyt, CEO of Tethers Unlimited, a small business in Washington state that was forced to lay off 20% of its workforce due to unpaid NASA contracts, describes the impact on contractors that may never see repayment or reimbursements. The Planetary Society has a petition to end the shutdown.

The new edition of The Planetary Report is now available to all, according to Senior editor Emily Lakdawalla.

Space Policy Edition: Canada's Uncertain Future in Space (with Kate Howells)
Canada was the third country in history to launch a satellite into space, but now lags in its space ambitions, capability, and spending. What happened? Kate Howells, who serves on the Canadian Space Advisory Board, joins the podcast to talk about the challenges facing Canada's future in space and how the nation needs to do a better job of communicating the benefits of space exploration to its citizens. Casey and Mat also look at the latest machinations of the U.S. congress, which has yet to fund NASA for 2019 and is rapidly running out of time to do so.
