Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center,

Episode 278, sticking the landing on Mars. I'm Gary Jordan, and I'll be introducing this episode.

On this podcast, we bring in the expert scientists, engineers, and astronauts,

all to let you know what's going on in the world of human spaceflight.

We're continuing with our reboot of our series that outlines a human mission to and from the Red

Planet. The eighth episode unfolds the intricacies of accomplishing a successful landing

for humans visiting the Red Planet. Houston, we have a podcast host Pat Ryan had a chance to chat

with the experts on this very topic. This episode was recorded on November 17th, 2020. Let's get started.

The subject is EDL, which stands for entry, descent, and landing, not at a decision list.

We have two guests. Doug Trent from NASA's Marshall Spaceflight Center in Huntsville, Alabama

is the Mars Architecture team's entry, descent, and landing lead. Doug has been working on the

Artemis human landing system program, HLS, for three years. So he's tied into how what we're

learning from Artemis at the Moon is feeding into the development of the systems to use on Mars.

Our second guest is Alicia Dwyer-Sianciolo from the NASA Langley Research Center in Hampton,

Virginia. She is the de-orbit, descent, and landing mission segment lead for the HLS,

and a member of the EDL team for NASA's Space Technology Mission Directorate. Alicia has

been embedded with the Mars Architecture team for years and has served on several science mission

directorate robotic mission teams. She actually has first-hand experience landing something on Mars.

She was on console during the Mars Curiosity Landing in 2012 and the Inside Mission Landing in 2018.

On this first Friday, our eighth episode on How to Get to Mars. Here we go.

In listening to the Mars Monthly Series, I've learned so much about a number of aspects,

what it takes to complete a successful trip to Mars. Emphasis is on successful. And I've come to
