NASA Selects Two Teams to Advance Life Sciences Research in Space

NASA Space Technology

NASA announced two awards Thursday to establish scientific consortia – multi-institutional coalitions to conduct ground-based studies that help address the agency’s goals of maintaining a sustained human presence in space. These consortia will focus on biological systems research in the areas of animal and human models, plants, and microbiology. When fully implemented, the awards for these consortia will total about $5 million.

Space biology efforts at NASA use the unique environment of space to conduct experiments impossible to do on Earth. Such research not only supports the health and welfare of astronauts, but results in breakthroughs on diseases such as cancer and neurodegenerative disorders to help protect humanity down on the ground.

The awards for the two consortia are for the following areas:

  • Studying space biosphere. The Biology in Space: Establishing Networks for DUrable & REsilient Systems consortium involves a collaborative effort between human/animal, plant, and microbial biologists to ensure an integrated view of the space flight biosphere by enhancing data acquisition, modeling, and testing. It will include participation of more than thirty scientists and professionals working together from at least three institutions. Led by Kristi Morgansen at the University of Washington in Seattle, Washington.
  • Converting human waste into materials for in-space biomanufacturing. The Integrative Anaerobic Digestion and Phototrophic Biosystem for Sustainable Space Habitats and Life Supports consortium will develop an anaerobic digestion process that converts human waste into organic acids and materials that can be used for downstream biomanufacturing applications in space. It will include eight scientists from six different institutions in three different states, including Delaware and Florida. The consortium is led by Yinjie Tang at Washington University in St. Louis, Missouri.

Proposals for these consortia were submitted in response to ROSES 2024 Program Element E.11 Consortium in Biological Sciences for a consortium with biological sciences expertise to carry out research investigations and conduct activities that address NASA’s established interests in space life sciences.

NASA’s Space Biology Program within the agency’s Biological and Physical Sciences division conducts research across a wide spectrum of biological organization and model systems to probe underlying mechanisms by which organisms acclimate to stressors encountered during space exploration (including microgravity, ionizing radiation, and elevated concentrations of carbon dioxide). This research informs how biological systems regulate and sustain growth, metabolism, reproduction, and development in space and how they repair damage and protect themselves from infection and disease.

NASA Teams Change Brakes to Keep Artemis Crew Safe

NASA Space Technology

Recently, teams with NASA’s Exploration Ground Systems (EGS) Program at the agency’s Kennedy Space Center met with engineering teams at a central Florida amusement park to share knowledge on a new braking system NASA is using for its launch pad emergency egress system for Artemis missions.

“We have a new magnetic braking system for the Artemis emergency egress system and NASA hasn’t used this technology on the ground infrastructure side before to support launches,” said Jesse Berdis, mobile launcher 1 deputy project manager for EGS. “I realized we have neighbors 50 miles from us in Orlando that are essentially the world experts on magnetic braking systems.”

For Artemis, teams will use a track cable that connects the mobile launcher to the terminus site near the perimeter of NASA Kennedy’s Launch Pad 39Bwhere four baskets, similar to gondola lifts, can ride down. This is where the magnetic braking system operates to help control the acceleration of the baskets in multiple weight and environmental conditions. At the pad terminus site, armored emergency response vehicles are stationed to take personnel safely away from the launch pad to a designated safe site  at Kennedy.

Many roller coaster manufacturers employ the use of an “eddy current braking system,” which involves using magnetics to help slow down a vehicle. Though the applications used on the roller coasters differ slightly from what the EGS teams are using for Artemis, the concept is the same, explained Amanda Arrieta, mobile launcher 1 senior element engineer.

However, unlike roller coasters which are typically in use daily for multiple hours on end, the Artemis emergency egress system is there for emergency situations only.

“We don’t plan to ever run our system unless we’re testing it or performing maintenance,” Berdis said.

Regardless of this, teams at Kennedy have ensured the system is able to function for years to come to support future Artemis missions.

“The maintenance crews [at the amusement park] were awesome because they showed us their nightly, monthly, and yearly inspections on what they were doing,” Berdis said. “That gave our operations teams a really good foundation and baseline knowledge of what to expect when they maintain and operate this system for the Artemis missions.”

Some of the conversations and suggestions teams shared include adding an acceleration sensor in the emergency egress baskets during testing. The sensor will help detect how fast the baskets are going when they ride down.

The emergency egress system is one of several new additions the EGS team is implementing  to prepare for future crewed missions starting with Artemis IIand this system especially emphasizes the importance of safety.

“We have a mission, and a part of that mission is in case of an emergency, which we don’t expect, is to protect our astronauts and supporting teams at the launch pad,” Berdis said. “We want our teams to be safe and, for any scenario we put them in, especially on the ground infrastructure side, it’s important for us to do our due diligence. That includes talking to other groups that are the experts in their field to ensure we have looked at all possibilities across the board to ensure our mission is a safe one for our teams.”

During the Space Shuttle Program, teams used a similar system for the escape route astronauts and other personnel take in the event of an emergency during a launch countdown. However, instead of using a magnetic braking system for the baskets, teams used a mechanical braking systemwhich involved using a catch net and drag chain to slow and then halt the baskets sliding down the wire.

For the agency’s Commercial Crew ProgramSpaceX also uses a catch net and drag chain for its slidewire cable at NASA Kennedy’s Launch Complex 39A pad and a deployable chute at Space Launch Complex 40 at Cape Canaveral Space Force Station. Boeing and United Launch Alliance also use a slidewire, but instead of baskets, the team deploys seats, like riding down a zip line, that ride down the slide wires at Space Launch Complex 41 at Cape Canaveral Space Force Station.

Under NASA’s Artemis campaignthe agency will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.
