After some time and effort, I have finished my early Space Shuttle era Astronaut status investigation.
The early Space Shuttle era astronauts in my definition are those from NASA Astronaut Group 7 to NASA Astronaut Group 9, the "Class of 1980" as they were all selected before the actual first flight of the Space Shuttle and flew during the early flights. Also included will be payload specialists that were selected by certain organizations to deliver specific payloads.
NASA Astronaut Group 7
Out of 7 people in this group, only 3 are alive.
Karol Bobko - From a rather recent public appearance I would say he is in decent shape.
Bob Crippen - Doing very well for his age, still quite active and involved, appears to be the healthiest of the 3 too.
Richard Truly - Has not been around much, did appear in the Challenger Final Flight documentary where another DeathLister said he seemed frail.
NASA Astronaut Group 8 "Thirty Five New Guys"
Out of 35 astronauts in this group, 25 are still alive and I was actually surprised to see so many of the TFNGs were still around. Because of the amount of astronauts from this group still alive, I am going to filter out those I know for sure are healthy, active and certain to be around for a while so whatever names that are missing are basically not immediate DL potential. Anyway let's move on.
John Creighton - John Creighton is an interesting case, he seemed to be actively involved in public life until Oct 2019 after which he suddenly stopped making public appearances, no virtual appearances or anything like that either. When someone active in public life suddenly disappears off the radar like this it's normally not a good sign.
Frederick Hauck - 81 years old. Definitely a bit frail in the last public appearance I could find of him also back in 2019 but unlike Creighton has not been active.
Loren Shriver - Frail, but still making appearances and giving interviews on occasion.
James Buchli - Didn't look great in a recent virtual appearance.
John Fabian - At 83 years old he is the oldest member of the group. He's not been around too much though looks to be doing okay. Interestingly enough John is on the Kennedy Space Center "Meet an astronaut" calendar for December 29, 2022 to January 02, 2023, we will see how that goes.
Mike Mullane - Though he's still quite active I have definitely noticed him getting frailer within the last year or so. Probably most notable for the creation of his book "Riding Rockets".
Robert Stewart - No news for years, last known photo I could find of him dates back to 2016 where he seemed to be doing fine but still it's quite a while ago.
Norman Thagard - Still somewhat around, attending events every once in a while. Looking frail now though.
James van Hoften - Again no news for years, last info I could find of him was back in 2009 where he moved to the UK to work in the board of directors for Gatwick Airport.
NASA Astronaut Group 9 "Class Of 1980"
Majority of this group are still alive so once again filters are to be applied here.
John Blaha - As mentioned earlier, he is rather frail now and has mostly stepped down from public appearances and events.
Ronald Grabe - Looked okayish in photos many years ago, no recent news.
Bryan Daniel O'Connor - No relation to the far more famous Sandra Day O'Connor. There hasn't been any info on Bryan since he retired from his position as a safety chief in NASA back in 2011.
Mary Cleave - Looked frail in virtual appearance in 2020, no news since then.
Bob Springer - Looks okayish in recent appearances.
While payload specialists aren't as well known as the proper NASA Astronauts, most of them usually get an obit.
Jake Garn - At 90 years old the oldest payload specialist, but is in" good health" and hopes to reach 100 years old according to a recent article which covered his 90th birthday celebration.
Taylor Wang - No news in forever.
William Pailes - Was still working as a teacher as of 2015 but no news since then.
Loren Acton - Seemed to be quite sharp in an interview 1 year back though physically he is definitely frail.
John-David Bartoe - No public news for a while but he was on the KSC "Meet an Astronaut" calendar just a few months ago so seems to be around still.
Samuel Durrance - As mentioned earlier, diagnosed with Alzheimer's disease recently and mostly using a wheelchair now.
