I would volunteer to, but I'm not sure I'll be making it this time. Sorry. -- moin moin, I'm working on getting something really interesting for March, but don't yet have anything for this week. Do you have a presentation or recommendation for something we can get for Thursday night in BigBlueButton? Aside from the meeting Stammtisch next Tuesday, Perseverance is also landing on Mars next week. Our last in person meeting was a panel of people working on multiple aspects of that mission. I'm looking forward to the landing and would have loved to join the Planeteary Society in Pasadena for the event. I'll still enjoy it online. ciao, der.hans --
