The Springer link is to the original TAGSAM paper--very interesting. I found it while doing a screw count of the below sampler head--there are 21 phillips-like head and 6 with allen head. The NASA press release [1] says "two of the 35 fasteners on the TAGSAM head could not be removed with the current tools approved for use." That doesn't match, which lead me to the Bierhaus et al. at Springer [2] which shows how they put the sampler head screws down into the dirt. The diagrams from Bierhaus and Walsh et al. [3] are both interesting. 0. https://www.nasa.gov/wp-content/uploads/2023/10/nelson-tagsam-shot-b.jpg https://www.nasa.gov/wp-content/uploads/2023/10/nelson-tagsa... 1. https://blogs.nasa.gov/osiris-rex/2023/10/20/nasas-osiris-rex-achieves-sample-mass-milestone/ https://blogs.nasa.gov/osiris-rex/2023/10/20/nasas-osiris-re... 2. https://link.springer.com/article/10.1007/s11214-018-0521-6 https://link.springer.com/article/10.1007/s11214-018-0521-6 3. https://link.springer.com/article/10.1007/s11214-022-00887-2 https://link.springer.com/article/10.1007/s11214-022-00887-2
