By the time you hear this week’s episode, China’s Tiangong-1 may have spectacularly re-entered our planet’s atmosphere, raining metal on an unpredictable location. The Aerospace Corporation’s Bill Ailor, an expert on space debris, tells us there’s little to worry about, but bigger challenges are ahead in low Earth orbit. Bruce Betts also has his mind on the small space station. Emily Lakdawalla is back from the Lunar and Planetary Science Conference with much news to share. NASA finally has a budget for the year already underway! Casey Dreier breaks it down.
