A pink glow is shining on the faces of enthusiastic students as they tend to plants in purpose-built grow boxes for space stations.

These students are the first in Australia to experience Growing Beyond Earth—a schools citizen science program from NASA and Fairchild Tropical Botanic Garden in the United States.

In Australia, Royal Botanic Gardens Victoria is working with the La Trobe Institute for Agriculture and Food, and Melbourne Archdiocese of Catholic Schools. The educational initiative ties into the Australian curriculum and gives students a unique introduction to gardening through science.

In this project, students grow plants in controlled conditions to test if they would be suitable for NASA missions, to help feed a future cadre of astronauts.

Plants evolved on Earth, so they might not grow so well in space.

On January 3, 2019, China's Chang'e-4 lander touched down on the far side of the moon and deployed the Yutu rover. In addition to its many instruments, the rover carried an important science experiment known as the Biological Experiment Payload (BEP). Over the next eight days, this payload conducted a vital experiment where it attempted to grow the first plants on the moon. Included in the payload were cotton, potato, arabidopsis, and rape seeds, along with fly eggs, yeast, and 18 ml (0.6 fluid oz) of water, which was kept at a constant atmospheric pressure.

The results of this experiment will help inform future Bioregenerative Life Support System (BLSS), which will prove vital to habitats and missions beyond Low Earth Orbit (LEO). A team of scientists from China recently released a study that reviewed the experiment, its results, and its potential implications for future missions to the moon, Mars, and other deep-space locations.

Research from West Virginia University students and faculty into how 3D printing works in a weightless environment aims to support long-term exploration and habitation on spaceships, the moon or Mars.

Extended missions in outer space require the manufacture of crucial materials and equipment onsite, rather than transporting those items from Earth. Members of the Microgravity Research Team said they believe 3D printing is the way to make that happen.

The team's recent experiments focused on how a weightless microgravity environment affects 3D printing using titania foam, a material with potential applications ranging from UV blocking to water purification. ACS Applied Materials and Interfaces published their findings.

"A spacecraft can't carry infinite resources, so you have to maintain and recycle what you have and 3D printing enables that," said lead author Jacob Cordonier, a doctoral student in mechanical and aerospace engineering at the WVU Benjamin M. Statler College of Engineering and Mineral Resources.
