(Vigna unguiculata) is selected as it
contains 25% protein several vitamins
and minerals. It is a fast-growing,
drought-tolerant legume, which can
thrive in various soil types and is widely
used in food preparations.
Various measurements,
including camera imaging, O and CO
concentration, RH, 22 temperature, and
soil moisture monitoring, were also
built into the module. Temperature
and pressure were automatically
maintained within the module and at
frequent intervals a measured quantity
of water was injected into the soil.
The seed germination was observed
on the fourth day of the experiment.
Later images showed the formation
of green leaves, indicating successful
commencement of photosynthesis. The
impact of the space environment on its
yield and growth is also being studied.
As we move towards setting up our
own Bharatiya Antariksh Station (BAS),
in situ plant cultivation is a critical
technology we need to master. Having
food production on board would
help the crew members to reduce
their dependence on Earth. There
are many other collateral benefits as
well, due to plant cultivation onboard.
They consume carbon dioxide and
release oxygen due to photosynthesis,
controlling humidity also in the process.
These processes help in managing the
cabin environment. In addition, having
green plants in the space habitats
creates much better ambience and
creates a very positive psychological
impact on the crew during all phases of
spaceflight.
