Astrodynamicist and space environmentalist (MAeroEngr鈥�01; PhD鈥�05) is among the prestigious 25-member cohort of the .
After receiving roughly 2,000 nominations per year from a pool of invited external nominators, the individuals demonstrating exceptional creativity and a history of significant achievement who are on the precipice of great discovery or a game-changing idea. Jah, a 澳门开奖结果2023开奖记录 alumnus, is one such individual.听
He won the fellowship for laying the foundation for a safe, prosperous and sustainable near-Earth space environment.听
鈥淢uch like people are keeping track of things moving on land, air and ocean, my job is to keep track of human-made things moving around in space,鈥� said Jah, associate professor of aerospace engineering and engineering mechanics at the University of Texas at Austin.

Saving Space
Jah鈥檚 work also involves policy guidance and public education concerning the framework of space environmentalism, which he likened to human exploration of Earth鈥檚 assets. 鈥淭hat [type of] exploration was led by those most resourced, and it always came to the detriment of the environment 鈥� we鈥檙e doing the same thing with space.鈥�
While Jah said he鈥檚 still in some disbelief about receiving a , he wants 鈥渢o invest these resources in me and my vision. Basically, I want space environmentalism to be mainstream across humanity. 鈥� I鈥檓 going to look for every means possible to be able to achieve that.鈥�
A challenge in his field, he said, is the lack of empathy toward solving the problem of space debris.听
鈥淭hat鈥檚 the most difficult thing 鈥� mostly because people don鈥檛 have the awareness of what the problem is,鈥� he said. 鈥淭hen once they learn about it, it鈥檚 hard for them to see why it should matter to them.鈥�
Jah strives to fix this by showing evidence 鈥渙f the dependencies that we have, certainly in western civilization, on space-based infrastructure, services and capabilities in our daily lives.鈥�
Together, Jah and his colleagues created a system to gather and catalog data through and , free online visualization tools they鈥檝e developed.听
The alarming amount of space congestion he tracks includes expired satellites that continue to travel at high speeds. When satellites stop functioning, they will hurtle through space for centuries or more, he said. While space is often thought of as large and infinite, Jah confirmed orbital highways 鈥� where satellites are placed 鈥� are very finite.
Just a few years ago, a dozen satellites were launched in a year. Now, 鈥渨e鈥檙e launching about a dozen satellites per week, at least,鈥� said Jah. 鈥淲e鈥檙e just sending stuff up but not coordinating it with other countries.鈥�
鈥淚t鈥檚 a recipe for the tragedy of the commons: Space could become unusable because we keep on participating in that finite resource without the benefit of planning, coordinating and even understanding the decision-making processes of other people that are doing that as well.鈥�
A Career Takes Off 听
鈥淲e鈥檙e just sending stuff up but not coordinating it with other countries.鈥�
Jah鈥檚 career is founded on astrodynamics 鈥� the science that studies motion of objects in space 鈥� orbit determination and statistics, 鈥渁s taught to me by the late George Born, professor emeritus and director for the Colorado Center for Astrodynamics Research.鈥�
Jah explained how Professor Born gave him the opportunity to work alongside him during graduate school at 澳门开奖结果2023开奖记录. 鈥淚 wasn鈥檛 a great test-taker; I didn鈥檛 do well on my GREs. ... But I did meaningful research and he said, 鈥業 want you to be a grad student here.鈥� It was an 鈥業 believe you should be here 鈥� now prove it to yourself鈥� sort of thing.鈥�
He fondly recalled his time as a student and the beauty of campus, where his son is now an undergraduate engineering physics major.
Among his favorite CU memories are the meaningful exchanges shared during dinners that Professor Born and his wife, Carol, hosted for graduate students. Additionally, Jah said his camaraderie with other students has lasted for years, as he continues to keep in touch with former classmates.听
On the Horizon
Looking ahead as a MacArthur Fellow, Jah underscored his belief in the interconnection of all things: 鈥漌e are in an existential crisis; our only way through it is by having a successful conversation with our environment,鈥� he said. 鈥淪tewardship is really what鈥檚 being asked for us to become, embrace and honor.鈥�
鈥淚 hope that my work is able to recruit empathy from people to raise awareness, show evidence of the interconnectedness and hopefully motivate people to see themselves as stewards of the environment.鈥�
