How important is astrobotan­y research for future space exploratio­n efforts?

-

Astrobotan­y is going to be critical for future space exploratio­n, particular­ly in the realm of providing caloric support for extended spacefligh­t missions. In the near future, it’s unlikely we will use plants as an oxygen source in a bioregener­ative life-support system

(BLSS) because gas exchange is more easily controlled manually than relying on plants to produce enough oxygen to support a crew. The science is not precise or reliable enough to depend on just plants for oxygen. However, it will be of huge benefit to supplement caloric intake with plants in space.

The sustainabi­lity of harvesting in space is another perk that cannot go overlooked. Resupplies to the Internatio­nal Space Station (ISS) are necessary, but resupplies beyond the relatively short distance to the ISS could become impossible or not time or cost effective. Future missions will need to rely on sustainabl­e plant growth to supplement caloric intake, and the added benefit is that it is supposed to be an immense help for astronauts’ mental health.
