Women on Spacecraft Missions: Are we moving towards parity with the percentage in the field?


The following blog post was written by Dr. Julie Rathbun, Senior Scientist at the Planetary Science Institute and Professor of Physics at the University of Redlands. The post was originally posted at the Women in Planetary Science blog, and is cross-posted here.



The photo above was taken during the July 2016 meeting of the Science Team for the Europa Multiple Flyby mission. All of the women at the meeting (most of whom are members of the science team) wanted to celebrate the accomplishments of women scientists by taking this photo. It was shot after Dr. Margaret Kivelson was honored by the Project with the Monolith award. During her speech, Margie discussed the challenges she’d faced over her more than 50 years as a scientist, many of those due to being one of a very small number of women scientists.

The Discovery Program Series: VERITAS (PI: Sue Smrekar, Managed by Jet Propulsion Laboratory)

This post is part of a series discussing the recent NASA Discovery Program mission selections for further refinement. From the 27 proposals submitted in November of 2014, NASA has selected 5 missions for further refinement in the next year. Part 1 of the series focused on the overview of the Discovery refinement selections and an interview with the Lead Program Scientist for the Discovery Program, Dr. Michael New. Part II focussed on the Psyche Mission (PI: Linda Elkins-Tanton, Arizona State University, Managed by JPL). Part III will focus on the NEOCam Mission (PI: Amy Mainzer, Jet Propulsion Laboratory, Managed by JPL). Part IV will focus on the Lucy Mission (PI: Hal Levison, Southwest Research Institute, Managed by NASA Goddard Space Flight Center). Part V will focus on the DAVINCI Mission (PI: Lori Glaze, Managed by NASA Goddard Space Flight Center). Part VI will focus on the VERITAS Mission (PI: Sue Smrekar, Managed by Jet Propulsion Laboratory).

Mission Overview: VERITAS

 VERITAS (Venus Emissivity, Radio Science, InSAR, Topography And Spectroscopy) is aimed at understanding one of the most fundamental questions in planetary evolution: Why are the twin planets Earth and Venus so different? Venus and Earth are nearly the same size and bulk compositions. Yet Earth ended up supremely habitable and Venus a sulfurous hell, where the surface temperature is hot enough to melt lead. Understanding how these two planets arrived at their present state is essential to understanding the evolution of rocky planets like Earth, and thus for predicting whether the Earth-sized planets in other solar systems are likely to be habitable. VERITAS will investigate Venus’ geologic evolution by obtaining global maps of high-resolution radar imaging, topography, and near infrared spectroscopy to constrain surface composition. This wealth of data will provide rich opportunities for discovery and inquiry for the next generation of planetary scientists and bring the information available for Venus on par with that for Mars, Mercury, and the Moon.

The Status of Mental Health in Planetary Science


This is a repost of Dr. Angela Zalucha's piece for the Women in Planetary Science Blog. Please see her original post here.

About Dr. Angela Zalucha: Angela Zalucha received her PhD in atmospheric science from MIT in 2010. She now works at the SETI Institute modeling the dynamics of planetary atmospheres. She currently lives in Boulder, CO where she enjoys skiing and volunteering in the clinic at the Humane Society of Boulder Valley.


I meant to write this article yesterday. That’s not a statement of procrastination. I suffer from depression, which was triggered a few years ago by events directly related to my career. The symptoms of depression are different from person to person. For me, I have to go lay in bed, in silence. Tasks like getting up to heat leftover pizza up in the microwave are insurmountable. So I wasn’t exactly up to the task of writing a blog article, even if it was about the condition I suffer from.

The Discovery Program Series: DAVINCI (PI: Lori Glaze, Managed by NASA Goddard Space Flight Center)

This post is part of a series discussing the recent NASA Discovery Program mission selections for further refinement.  From the 27 proposals submitted in November of 2014, NASA has selected 5 missions for further refinement in the next year. Part 1 of the series focused on the overview of the Discovery refinement selections and an interview with the Lead Program Scientist for the Discovery Program, Dr. Michael New. Part II focussed on the Psyche Mission (PI: Linda Elkins-Tanton, Arizona State University, Managed by JPL). Part III will focus on the NEOCam Mission (PI: Amy Mainzer, Jet Propulsion Laboratory, Managed by JPL).  Part IV will focus on the Lucy Mission (PI: Hal Levison, Southwest Research Institute, Managed by NASA Goddard Space Flight Center). Part V will focus on the DAVINCI Mission (PI: Lori Glaze, Managed by NASA Goddard Space Flight Center).

Mission Overview: DAVINCI

The Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission would send a probe on a journey down through Venus’ atmosphere, winding up in the planet’s roughest and most geologically complex terrain. The probe would explore the planet’s atmosphere essentially from top to bottom, even the deep layers largely hidden from Earth-based instruments and orbiting spacecraft. DAVINCI would be the first U.S. probe to target Venus’ atmosphere in nearly four decades.

The top-level goals of DAVINCI are to
Understand the origin of the Venus atmosphere, its evolution and why it is different than Earth and Mars,
Understand the history of water on Venus and chemical processes at work in its lower atmosphere, and
Provide insight into tessera origins and their tectonic and weathering history.

DAVINCI is designed to study the makeup of the planet’s atmosphere at a level of detail that has not been possible on earlier Venus missions and to investigate the surrounding surface with cameras. DAVINCI will fly two different types of mass spectrometers, as well as temperature and pressure sensors, to explore how Venus’ atmosphere formed and then changed over time, including what happened to its water. The findings would help scientists understand why Venus and Earth took such different paths as they matured and provide another point of comparison for studies of rocky planets in other star systems. Goddard would manage the mission, which launches in 2021 and descends through the Venus atmosphere in 2023.

The Discovery Program Series: Lucy (PI: Hal Levison, Southwest Research Institute, Managed by NASA Goddard Space Flight Center)

This post is part of a series discussing the recent NASA Discovery Program mission selections for further refinement.  From the 27 proposals submitted in November of 2014, NASA has selected 5 missions for further refinement in the next year. Part 1 of the series focused on the overview of the Discovery refinement selections and an interview with the Lead Program Scientist for the Discovery Program, Dr. Michael New. Part II focussed on the Psyche Mission (PI: Linda Elkins-Tanton, Arizona State University, Managed by JPL). Part III will focus on the NEOCam Mission (PI: Amy Mainzer, Jet Propulsion Laboratory, Managed by JPL).  Part IV will focus on the Lucy Mission (PI: Hal Levison, Southwest Research Institute, Managed by NASA Goddard Space Flight Center).

Mission Overview: Lucy

Lucy is a survey of the Trojan asteroids.  Because of their location near Jupiter's orbit, Trojans are a unique resource for deciphering the history of the outer Solar System, which includes the formation of the giant planets and Kuiper belt, planet migration, and delivery of volatiles to the terrestrial planets.  Theories predict that these objects formed throughout the outer planetary system and were captured in their current orbits as the planets grew and moved around. This is evidenced by the fact that we see three distinctly different types of objects in the Trojan swarms. Thus, in order to truly understand what these objects are telling us about the history of the Solar System, we must survey this diversity - Lucy is designed to do just that.  Lucy will flyby at least 4, and probably 5, Trojans covering all the known spectral types in both the L4 and L5 swarms.  It will visit the largest member of a catastrophic collisional family, thereby supplying vital clues about accretional process.  It will also study a near-equal mass binary, which may be a rare survivor from the first generation of planetesimals.  Lucy's payload includes a high resolution panchromatic camera (based on New Horrizon's LORRI), a color imager and NIR spectroscopic mapper (based on New Horrizon's Ralph), and Thermal IR spectrometer (based on OSIRIS-REx's OTES).

The Discovery Program Series: NEOCam (PI: Amy Mainzer, Jet Propulsion Laboratory, Managed by JPL)

This post is part of a series discussing the recent NASA Discovery Program mission selections for further refinement.  From the 27 proposals submitted in November of 2014, NASA has selected 5 missions for further refinement in the next year. Part 1 of the series focused on the overview of the Discovery refinement selections and an interview with the Lead Program Scientist for the Discovery Program, Dr. Michael New. Part II focussed on the Psyche Mission (PI: Linda Elkins-Tanton, Arizona State University, Managed by JPL). Part III will focus on the NEOCam Mission (PI: Amy Mainzer, Jet Propulsion Laboratory, Managed by JPL).

Mission Overview: NEOCam 

The Near-Earth Object Camera (NEOCam) mission will permit the most comprehensive inventory ever made of our solar system’s small bodies (asteroids and comets) using a space-based infrared survey telescope. NEOCam will detect millions of asteroids, enabling unprecedented understanding of their origins, evolution, and physical properties, and significantly reducing the risk of an unwarned impact on the Earth. NEOCam will detect approximately ten times more near-Earth objects (NEOs) than are known today, making significant progress toward the direction given to NASA by the U.S. Congress to discover more than 90% of near-Earth objects large enough to cause significant regional damage.

The Discovery Program Series: Psyche (PI: Lindy Elkins-Tanton, Arizona State University, Managed by JPL)

This post is part of a series discussing the recent NASA Discovery Program mission selections for further refinement.  From the 27 proposals submitted in November of 2014, NASA has selected 5 missions for further refinement in the next year. Part 1 of the series focused on the overview of the Discovery refinement selections and an interview with the Lead Program Scientist for the Discovery Program, Dr. Michael New.  Part II will focus on the Psyche Mission (PI: Linda Elkins-Tanton, Arizona State University, Managed by JPL). 

Mission Overview: Psyche

How did the Earth’s core and the cores of the other terrestrial planets come to be? We cannot observe them directly, but there is one place in the solar system where we can find answers: The metal asteroid Psyche. Every world explored so far has a surface of ice, rock, or gas. Orbiting in the outer main belt at 3 AU, Psyche is large (240 x 185 x 145 km), dense (as high as 7,000 kg/m^3), and made almost entirely of Fe-Ni metal.

The Discovery Program Series: Introduction and Interview with Michael New (Lead Program Scientist)

As stated on the NASA website, NASA's Discovery Program gives scientists the opportunity to dig deep into their imaginations and find innovative ways to unlock the mysteries of the solar system. When it began in 1992, this program represented a breakthrough in the way NASA explores space. For the first time, scientists and engineers were called on to assemble teams and design exciting, focused planetary science investigations that would deepen the knowledge about our solar system.
