Astronaut Scientific Debriefings, 1962-1963

National Aeronautics and Space Administration · 1962 · 216 pages · text from the file's own layer

This NASA file of astronaut scientific debriefing papers from 1962 collects internal Office of Space Sciences material on the science observations made on early Mercury flights. A February 1962 memo from Maurice Dubin asks for more detail on John Glenn's report of luminous particles and the atmospheric horizon layer. A draft memo concludes that the particles were tied to the spacecraft and were not extraterrestrial. The file also holds a Los Alamos letter that attributes the high haze layer to nitrogen peroxide, and notes on Carpenter's airglow observations.

From the source:Release of 2026-06-12 This file contains memoranda, correspondence, reports, and other materials relating to contemporary scientific interest in investigating the nature of luminous phenomena reported by astronauts John Glenn and Walter Schirra during spaceflight. This collection includes transcripts from NASA interviews and debriefings with both astronauts regarding those observations. It also contains details relating to scientific observations of atmospheric phenomena, including brief descriptions of luminous particles, experiences while aboard spacecraft, and circa 1955 theoretical analysis of meteoric particles entering the atmosphere. Pages 34-35, 55-56, 57-63, 64-113, and 122-127 feature content relevant to the PURSUE initiative.

Tennyson - It's good to have somebody else who isn't constrained to
party lines.
Gill - It's a privilege to meet with you, really.
Tennyson - Something that shocks me is that the discussion from
Scott Carpenter and your discussion is the picking out of clues
from about, heaven knows, how many scientific disciplines from
your general experience etc., and integrate them all together and
be able to present them; frankly, I just find this very interesting
that anybody can do that. The wide range of experience.
Schirra - I think it's the opportunities of so many exposures we've
had and we have taken advantage of them, and as an example, we can
have an audience with you people anytime we call, and if we have
questions and this is true throughout the whole pr ogram. I can
talk to Von Braun if I'd like to right now. I can talk to a technici an
that's working on a nut and bolt on Von Braun's booster right now.
We have this prerogative which is very great for us. We are not
stuck with the disciplines of crossing party lines or anything like
this or going up to the ladder and back down again . We go - we
just take a straight path to where we want to get information . It
is a tremendous opportunity -for us, and we try not to abuse it, but
we use it liberally really. I might add that anytime you have a
question, our phones are always available for this kind of thing.
r
Don ' t ever think we are incommunicado.
Shoemaker - Good - that's very good, Commander. I'd like to thank
you very much.
Schirra - Sure, I was glad to come by.
