NASA Funds Development of Mars Balloon

A future Mars mission could include instruments attached to balloons, providing the capability to study places where rovers can't go, while offering a closer look than orbiting satellites. NASA has awarded a Small Business Innovative Research (SBIR) Phase I contract to Aurora Flight Sciences and its partner Vertigo Inc, to develop an autonomous balloon launcher to operate from the surface of Mars. Aurora is looking to develop a compact lightweight system that could be included on future Mars landers, augmenting the mission with a small aerial vehicle. Such a system would have potential for atmospheric sampling and video data capture unavailable on current Mars missions.

Balloon-based Mars exploration has the capability to cover a larger portion of the Martian surface than is accessible via a rover and to provide better resolution than is available from satellites. Balloons could be used to measure atmospheric data at different altitudes and locations on Mars.

"A major challenge to ground deployment is the possibility of the envelope being damaged by winds, surrounding rocks, or parts of the associated lander," said the project's manager, George Kiwada. "Our Shielded Mars Balloon Launcher (SMBL) concept addresses this challenge by using inflatable structures to provide a safe environment for balloon inflation and deployment."

Balloons have been flying for decades in Earth's stratosphere, which has an atmosphere as thin as that on the surface of Mars. Conventional stratospheric balloons have lifetimes limited to a few days because of the daily heating and cooling of the balloon. Helium superpressure balloons, currently under development for the Ultra Long Duration Balloon (ULDB), will fly more than 100 days and perhaps as long as a year. Smaller superpressure balloons carrying payloads of only a few kilograms have already flown for as long as a year.

Aurora's has done previous work with NASA on the development of a Mars airplane. In that project, Aurora became familiar with the challenges of aerial vehicle operations in the Martian atmosphere.

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
