Podcaster: Loretta Cannon for the AAS-HAD ; Guest: Dr. Candice Hansen-Koharcheck, Dr. Linda Spilker
Title: H’ad astra historia Ep 202 – Say Cheese
Organization: Historical Astronomy Division
Link: https://had.aas.org/
Description: Today’s guest: : Dr. Candice Hansen-Koharcheck is a Senior Scientist with the Planetary Science Institute. Dr. Linda Spilker is a JPL Fellow and Senior Research Scientist with NASA’s Jet Propulsion Laboratory, and she’s the Voyager Project Scientist. We’re celebrating the 35th anniversary of the first and only Portrait of the Solar System, a series of 60 images taken by Voyager 1 on 14 Feb 1990. Dr. Hansen-Koharcheck tells us the rarely-told story behind how this portrait eventually was created (hint: it took 8 years and 7 requests).
H’ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society. We’re here to share stories from and about the people who study the stars, planets, and the cosmos. We’ll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were “in the room” during pivotal events within the last 50 years or so.

Sue Linick: from the December 2021 monthly JPL newsletter ‘Universe’.pdf
“Sue Hanson Linick, 71, died from pancreatic cancer on Nov. 13, 2021. Sue was born and raised in Los Angeles and in La Crescenta, and began working at JPL as a clerk-typist in 1968 when she was 18 years old. She retired from the Lab as an engineer/engineering manager in 2015. Sue worked in mission and science operations on many flight projects, including Viking, Voyager, and SIRTF, and was the instrument operations manager on Cassini. She loved her time at JPL, both for the excitement of mission operations, and for the many close friends she made over the years. Sue had a wonderful retirement, travelling widely – Alaska, Scandinavia, Russia, Germany, Dubai, South Africa, Egypt, Jordan, New Zealand, and many national parks. She became an avid and talented quilter and loved giving her finished quilts to friends and family. Sue is survived by her husband of 41 years, Dave; sons Justin and Christopher; all of whom followed her lead and worked at JPL. In lieu of flowers, the family recommends a donation to the Pancreatic Cancer Action Network (PanCAN) or to the charity of your choice.”

Voyager Mission Status: https://science.nasa.gov/mission/voyager/where-are-voyager-1-and-voyager-2-now/
This page has a table that shows (in real time) elapsed mission time and the distance each spacecraft has traveled (distance from Earth or the Sun). During the Spring (for folks in the northern hemisphere) the distance from Earth will be decreasing; this is normal because the Earth moves around the Sun each year.

This page is a real treat! You can ‘see’ the spacecraft’s location in real time, or you can move it backwards to watch its travels since 1977, and so much more.
