Fresno planetary scientist draws lessons on climate change from space exploration

It’s Feb. 18 and my co-workers and I anxiously watch as the Mars 2020 Rover,
Perseverance, approaches the Martian atmosphere. Our mission is to
capture an image of the 70-foot-wide supersonic parachute that will slow
the rover during descent onto Mars. Millions of people around the globe
are watching via live stream as we operate the high-resolution camera, HiRISE, aboard the Mars Reconnaissance Orbiter.
Traveling at 6,750 mph, the extreme distance and high speeds of
the two spacecraft created challenging conditions that required precise
timing so the rover was viewable by HiRISE at just the right moment.
This interplanetary action-shot required arduous amounts of
collaboration, calculations, and specialized software, but the result is
awe-inspiring.
As a planetary scientist, I see space exploration as a way to
understand where we come from. It allows us to learn how life began, and
what it might be like in extreme environments.
We know that the Earth has gone through drastic changes over its
long history. While “life” in general has survived, the type of life
that survives is always that which has adapted and thrived in a changing
world. The relative climatic calm on the Earth for the last 2,000 years
has allowed humans to become a technologically and culturally advanced
species. Unfortunately for us, that calm has ended. Severe and
unprecedented weather events have overwhelmed the U.S. in the last few
years: catastrophic flooding in the Midwest, large-scale fires in the
West, the polar vortex causing record-breaking freezes in Texas this
year.
Recent trends of severe weather are telling us that we need to
prepare for a future that will be unfamiliar. This means societal and
infrastructure change on many levels — economically, socially, and
politically. However, humans have a great survival advantage for facing
climate change. We have grown a collective base of knowledge to innovate
in ways that would have seemed pure fiction a hundred years ago. From
my own experience working on active spacecraft missions, I know that
when a community of people come together around a common idea, we can
face any challenge and succeed.
The vast majority of scientists and Americans agree that climate
change is real, caused by excessive carbon emissions, and will have
serious impacts on the health and livelihoods of themselves and their
loved ones. While some industries are already reducing their carbon
emissions, others will not move forward until there is a plan to
incentivize them. Putting a gradually rising fee on emissions from coal,
oil, and gas will drive down carbon pollution because energy companies
and leading industries will innovate toward cleaner, cheaper options.
It is a lofty goal to cut carbon emissions to stabilize our
climate, while allowing us to carry on with the benefits that abundant
energy has given us. This goal may feel as unattainable as landing on
the moon once did. In the 1960s, President Kennedy’s famous “Moon
Speech” at Rice University in Texas about the space program inspired a
nation to explore new horizons and technology. Our country has led
exploration into space, and this race towards a clean energy future is
our generation’s moonshot. As the 52nd anniversary of the Apollo
missions and 51st anniversary of Earth Day
is Thursday, I reflect on JFK’s famous words half a century ago and
compare the race to the moon to the challenge of climate change:
Why should we lead innovation towards a clean energy future? Not
because it is easy, but because it is hard, because that goal will serve
to organize and measure the best of our energies and skills, because
that challenge is one we must accept, one we cannot postpone, and one in
which we intend to succeed. We have our future, and the future of every
living thing on this Earth at stake; this is not a race we can lose.
