Shooting For The Stars

Staff Writers

Elizabeth Jens knew from the age of 12 that she wanted to be an astronaut. Now living in the US and working at NASA, she shares her experience, and a newfound sense of optimism of Australia’s growing space industry.

I am a propulsion and systems engineer at the NASA Jet Propulsion Laboratory in California. I share my time between systems engineering for Mars missions and propulsion technology development for small spacecraft. I am currently working on a small cold-gas system that will be used on the Perseverance Rover. This system sits on the rover’s arm and is used to clear dust from the surface of rock samples so that they can be imaged and analysed by the rover’s scientific instruments. I am also a system engineer for the Mars Ascent Vehicle. The Mars Ascent Vehicle is a part of the proposed Mars Sample Return effort, where we hope to bring samples collected by the Perseverance rover back to Earth. The Mars Ascent Vehicle is the rocket that is being designed to launch from the surface of Mars and deliver the samples to Mars orbit. 


I have wanted to be an astronaut since I was around ten or twelve years old. A couple of events occurred around this time that set me on my current path. The first was a gift from my dad, a book titled Mission to the Planets by Patrick Moore. The book was filled with gorgeous images of our solar system, descriptions of each of the planets and moons, and discussions of the missions that taught us about them. I loved reading about the various robotic missions and realising how much more there was for us to discover. Around the same time, my family went to hear the Apollo astronaut Charlie Duke speak. Listening to him talk, in front of images of him standing on the moon, made me realise that as incredibly talented as astronauts are, they are also human. I left that talk wanting to be an astronaut and just kept thinking: “Why not me? If I work hard and stay healthy, why could I not be that person standing on the moon one day?” The combination of the book and the talk made me realise that I love learning and exploring. I still hope to be an astronaut one day, but I also really love my engineering role at JPL and would be more than happy spending the rest of my career helping humankind to explore our solar system in this capacity.



I knew that I wanted to pursue further study in aeronautics and astronautics when I completed my undergraduate degrees at the University of Melbourne. I loved Australia but was captivated by the idea of playing an active role in space exploration, and so I moved to the United States for my graduate studies. I arrived at Stanford University and threw myself into academic life there, thrilled to finally be taking classes on topics like rocket propulsion and orbital dynamics. The academic transition was fairly smooth. I found that my undergraduate physics and engineering education put me on equal footing with my peers at Stanford. The move from academia into industry was more of a challenge, however, as it was difficult to find roles in this field as a foreign national. Thankfully, difficult is not the same as impossible, and I was lucky enough to intern at JPL during my time at Stanford. I now work in the same group at JPL that I interned with nearly a decade ago. 


I’m often asked for advice to pass on to those who are also interested in a career in the space sector. In general, my response is that if you are passionate about a career in this field, then do not be daunted about pursuing it. Do not be afraid to receive some rejection, just remember that you only need one “yes”. You need to be prepared for the roadblocks and remain willing to work hard and stay motivated whilst you look for your opportunity. It is worth highlighting too that it is such an exciting time right now for Australians who are passionate about space exploration. We are seeing rapid growth of the Australian space industry and with it, a wealth of new opportunities in the sector. 


It is an uncertain period for the world right now, and it is easy to get down about the state of our planet and species. Space exploration is one area we can look to for some uplifting developments. In 2020, multiple missions to Mars will be launched. Amongst these is the NASA rover, Perseverance. It will be travelling to Mars to search for signs of life, and to collect rock samples with the goal of follow-on missions potentially bringing those samples back to Earth for analysis. I’m excited about the possibility of discovering alien life, and how that might change our thinking of our place in the universe. Even if we do not find evidence of past or present life on Mars, then I’ll be keeping an eye on Titan and Europa. Both of these moons could potentially support some form of life, and both have missions in development now to enable us to learn more about them. As individuals, many of us are sheltering in place right now, but as a species, we’re continuing to explore and reach into the cosmos with these missions.

In 2016 I published a blog article titled Moonshots for Australia: 7 For Now. It’s one of many I have posted on business and innovation in Australia. In that book, I highlighted a number of Industries of the Future among a number of proposed Moonshots. I self-published a book, Innovation in Australia – Creating prosperity for future generations, in 2019, with a follow-up COVID edition in 2020. There is no doubt COVID is causing massive disruption. Prior to COVID, there was little conversation about National Sovereignty or supply chains. Even now, these topics are fading, and we remain preoccupied with productivity and jobs! My motivation for this writing has been the absence of a coherent narrative for Australia’s business future. Over the past six years, little has changed. The Australian ‘psyche’ regarding our political and business systems is programmed to avoid taking a long-term perspective. The short-term nature of Government (3 to 4-year terms), the short-term horizon of the business system (driven by shareholder value), the media culture (infotainment and ‘gotcha’ games), the general Australian population’s cynical perspective and a preoccupation with a lifestyle all create a malaise of strategic thinking and conversation. Ultimately, it leads to a leadership vacuum at all levels. In recent years we have seen the leadership of some of our significant institutions failing to live up to the most basic standards, with Royal Commissions, Inquiries and investigations consuming excessive time and resources. · Catholic Church and other religious bodies · Trade Unions · Banks (and businesses generally, take casinos, for example) · the Australian Defence Force · the Australian cricket teams · our elected representatives and the staff of Parliament House As they say, “A fish rots from the head!” At best, the leadership behaviour in those institutions could be described as unethical and, at worst….just bankrupt! In the last decade, politicians have led us through a game of “leadership by musical chairs” – although, for now, it has stabilised. However, there is still an absence of a coherent narrative about business and wealth creation. It is a challenge. One attempt to provide such a narrative has been the Intergenerational Reports produced by our federal Government every few years since 2002. The shortcomings of the latest Intergenerational Report Each Intergenerational Report examines the long-term sustainability of current government policies and how demographic, technological, and other structural trends may affect the economy and the budget over the next 40 years. The fifth and most recent Intergenerational Report released in 2021 (preceded by Reports in 2002, 2007, 2010 and 2015) provides a narrative about Australia’s future – in essence, it is an extension of the status quo. The Report also highlights three key insights: 1. First, our population is growing slower and ageing faster than expected. 2. The Australian economy will continue to grow, but slower than previously thought. 3. While Australia’s debt is sustainable and low by international standards, the ageing of our population will pressure revenue and expenditure. However, its release came and went with a whimper. The recent Summit on (what was it, Jobs and Skills and productivity?) also seems to have made the difference of a ‘snowflake’ in hell in terms of identifying our long-term challenges and growth industries. Let’s look back to see how we got here and what we can learn. Australia over the last 40 years During Australia’s last period of significant economic reform (the late 1980s and early 1990s), there was a positive attempt at building an inclusive national narrative between Government and business. Multiple documents were published, including: · Australia Reconstructed (1987) – ACTU · Enterprise Bargaining a Better Way of Working (1989) – Business Council of Australia · Innovation in Australia (1991) – Boston Consulting Group · Australia 2010: Creating the Future Australia (1993) – Business Council of Australia · and others. There were workshops, consultations with industry leaders, and conferences across industries to pursue a national microeconomic reform agenda. Remember these concepts? · global competitiveness · benchmarking · best practice · award restructuring and enterprising bargaining · training, management education and multiskilling. This agenda was at the heart of the business conversation. During that time, the Government encouraged high levels of engagement with stakeholders. As a result, I worked with a small group of training professionals to contribute to the debate. Our contribution included events and publications over several years, including What Dawkins, Kelty and Howard All Agree On – Human Resources Strategies for Our Nation (published by the Australian Institute of Training and Development). Unfortunately, these long-term strategic discussions are nowhere near as prevalent among Government and industry today. The 1980s and 1990s were a time of radical change in Australia. It included: · floating the $A · deregulation · award restructuring · lowering/abolishing tariffs · Corporatisation and Commercialisation Ross Garnaut posits that the reforms enabled Australia to lead the developed world in productivity growth – given that it had spent most of the 20th century at the bottom of the developed country league table. However, in his work, The Great Reset, Garnaut says that over the next 20 years, our growth was attributable to the China mining boom, and from there, we settled into “The DOG days” – Australia moved to the back of a slow-moving pack! One unintended consequence of opening our economy to the world is the emasculation of the Australian manufacturing base. The manic pursuit of increased efficiency, lower costs, and shareholder value meant much of the labour-intensive work was outsourced. Manufacturing is now less than 6% of our GDP , less than half of what it was 30 years ago!
