Talks for our upcoming virtual-only 25 Oct meeting and a SAVE THE DATE for 4 Nov field trip

The presentations will include talks by Geoffrey S. Ellis (USGS, Denver) on “Geologic hydrogen: An overlooked potential primary clean-energy resource“, Jack Conrad (NASA, Marshall Space Flight Center) on “Sampling Geologic Properties of Mars’ Crust with Secondary Crater Clusters“, and Kathryn Watts (USGS, Spokane) on “Mining the Science of the Nation’s Premier Rare Earth Element Deposit at Mountain Pass, CA“. A meeting flyer is available here. The GSW will also be having a daylong field trip on Saturday, Nov. 4, which will include a stop along the falls of the James River in downtown Richmond, VA. It will probably start around 9 AM and finish around 4 PM. Further details will follow shortly.

4 Oct GSW meeting (the 1592nd) is at the Cosmos Club

It is an IN-PERSON meeting only. It will feature talks on space weather, experimental petrology, and exploration of the planet Mercury, and of course, an informal presentation on the spectacular return of the asteroid samples from OSIRIS-REx. We will begin with a talk by Yarieska Collado-Vega (GSFC) on the ‘Moon to Mars Space Weather Analysis Office: Support for NASA missions and the Artemis program’. Next up will be Megan Mouser (Carnegie) talking on ‘Exploring early planetary formation processes using high-pressure, high-temperature experimental techniques’. The final talk of the evening will be presented by Shoshana Weider (NASA Hq) on ‘Mercury Exploration: Past, Present, and Future’. Abstracts of the talks, and biographies of the speakers, are here. This meeting has proven more difficult than most to assemble because of a possible government shutdown. So details of the talks, and even who the speakers will be, was still in a state of flux until two days before the meeting. Many of you will remember our last US government shutdown in 2019, which extended for more than a month. We had several in-person GSW meetings during that time, and I vividly remember the circumstances because I was your GSW president. It was a time of improvisation, and my favorite event was showing selected cartoons from Richard (Rick) Blakely (USGS-Emeritus) as a stress reliever. One final issue: we are having some problems accessing our archives, and so Tim Mock was unable to provide the history slide during our last meeting. That slide has been a part of the background of our meetings for as long as I have been at GSW. It seems to be a problem associated with our web server, and I am working this issue, as are several others. Everything else for the meeting should be the same: Come at 7:30 PM to socialize and imbibe, the meeting begins at 8 PM, and ends by 10 PM.

Bradley Lecture by Paul Richards (Lamont) is this coming Wednesday (13 Sep) evening at AGU (2000 Florida Av)

Traditionally, the GSW has adjourned for the summer months to provide time for fieldwork. Our named lecture, the Bradley, will restart the GSW fall season, and will be given by Paul G. Richards, of the Lamont-Doherty Earth Observatory. It will be held this year at AGU Headquarters (2000 Florida Av. NW), beginning at 8 PM on Wednesday, 13 September. Come at 7:30 PM for socializing (AGU usually has gratis snacks and drinks). The Bradley lecture, ‘Precision Seismology with applications to signals Old and New’ will be 60 minutes with questions to follow. The abstract, and biography, are here, and a flyer is here. You will be asked to sign-in when you enter the AGU building, after you tell them that you will be attending the Bradley lecture of the GSW. If you use the Metro (Red line) you’ll get off at the Dupont Circle stop, and walk north a few blocks on Connecticut to Florida Av. Take a gentle right, and AGU will be on your right in the next block. If you are interested in getting dinner beforehand in the area, the Washington Post had a nice piece last week (7 Sept) on the Square, DC’s new dining collective, located at Farragut Square. Check out the review here.

3 May 2023 GSW meeting (the 1590th) is at the Cosmos Club

and will be a Cryosphere-themed meeting. It will be an in-person meeting ONLY. We have talks about measuring our changing Cryosphere one photon at a time (Neumann, NASA GSFC), weighing the Cryosphere and monitoring its changes with the GRACE Follow-On satellite mission (Croteau, NASA GSFC), and using geophysical environmental data to support operations in Sea & Lake ice (Clark, USNIC). A flyer is here, and abstracts, bios & pics are here. The meeting will be held at the Cosmos Club (7:30 PM for socializing, 8 PM for talks. Stay tuned for further updates.

Draft minutes of 12 April meeting (1589th GSW)

Our meeting secretary, Graham Lederer, has kindly provided the following draft minutes of our last meeting. Let him know of any additions or corrections at glederer[at]usgs.gov.

12 April GSW meeting (the 1589th) is at the Cosmos Club

and is an IN-PERSON meeting ONLY. It will feature talks about the DARPA/USGS AI for Critical Mineral Assessment (Elliott; DARPA), National Flood policy (Honeycutt; Atkins, formerly White House OSTP), and constraining maximum earthquake ground motions (Pratt; USGS). A poster is here. Blurbs, Bios, and Pictures are here. Join us at the Powell auditorium beginning at 7:30 PM to socialize, or at 8 PM for the talks.

NOT the 1589 GSW meeting (30 March 2023)

The informal ‘meet and greet’ for the Crew-4 International Space Station astronauts at the Cosmos Club was attended by about 40, many of whom were scientists with their families who wanted to meet an astronaut. After a 20 minute narrated video from the astronauts, four NASA/UMD scientists with GSW & Cosmos Club experience (Killen, Kirschbaum, Cohen and Martos) gave short (4 minute) presentations to the astronauts about topics that have direct relevance to the return of humans to the Moon. The astronauts responded with interest, and good questions. At the end of the meeting the astronauts presented a plaque to the Cosmos Club and GSW.

Do you want to meet an astronaut (or 3)?

If so, the GSW, in conjunction with the Cosmos Club, is hosting a ‘Meet and Greet’ the evening of Thursday, March 30th for the recently returned Crew-4 astronauts. The event will be in the Crentz Room on the 2nd Floor of the Cosmos Club. We hope the meeting will begin about 6 PM tomorrow night (Thursday) for about an hour. Please adhere to the Cosmos Club’s dress code: “Gentlemen are expected to wear jackets, dress slacks, a collared long-sleeved shirt (tucked-in) or turtleneck. Ladies are expected to dress in an equivalent fashion”. The recently returned International Space Station (ISS) astronauts include one, Astronaut Dr. Jessica Watkins, who received a Ph.D. in geology from UCLA on the topic of ‘Tectonic and Aqueous processes in the formation of mass-wasting features on Mars and Earth’ in 2015 under the direction of Professor An Yin. Note that the event is on THURSDAY, not our traditional Wednesday. We hope that you (and your family) may be able to attend this event. Present yourselves at the front door of the Cosmos Club, and tell them that your host is Steve Mackwell, and that you are here for the astronaut meet and greet. Further information is available from purucker[at]alumni.caltech.edu. Hope to see you there.
