Imagine a spacecraft with no crew entering a planet’s atmosphere at over 12,500 mph having to come to stop in seven minutes. And operating in temperatures of...
A microresonator that SMU helped create for NASA is seen in a lab at SMU on Friday, July 8, 2022. The microresonator pictured was made using an optical fiber, which is red wire seen, and is 1 mm, while the one created for NASA is 2 mm. The NASA-funded team led by SMU researchers think that their small, lightweight device developed to measure spaceship velocity will improve the odds of successful landings on Mars and other planets.
By creating these smaller devices for Mars missions, researchers say that there’s more room for fuel and other critical supplies – and also for samples taken from the red planet. Improving our understanding of Mars through these remotely operated missions then helps scientists reduce the risks for future human exploration.But humans have only been exploring space for a little over 60 years.
“My sense is that space travel unleashes all kinds of imagination,” said Ötügen, an SMU senior associate dean of the Bobby B. Lyle School of Engineering and professor of mechanical engineering. Research assistant Jaime da Silva photographed with a microresonator that SMU helped create for NASA in a lab at SMU on Friday, July 8, 2022. The microresonator pictured was made using an optical fiber, which is red wire seen, and is 1 mm, while the one created for NASA is 2 mm. The NASA-funded team led by SMU researchers think that their small, lightweight device developed to measure spaceship velocity will improve the odds of successful landings on Mars and other planets.
Through this same phenomenon, light fed into the device developed by Ötügen’s team travels around the cavity of the device millions of times. By recording shifts in the light’s frequency as the spacecraft travels, the device allows scientists to measure velocity and acceleration with very high precision.
