KEY PROBLEMS THAT SPACE
TRAVELLERS NEED TO SOLVE
FOODS - GREEN HOUSE IN SPACE
Plotting plants in the space is challenging, as you don't
have gravity.
NASA is conducting various experiments to grow
plants at International Space Station. Scientists
constructed a special greenhouse consisting of a
control module and two independent vegetation
modules, which allows for comparisons in growing
treatments. The compact size and wall-mount
capability of the units make them ideal for the close
quarters in the space station. Scientists investigate the
samples from the units that have been up on the
station and look for what microbes are growing within
this system. They also need to ensure the
space-grown crops are safe to eat.
In addition to identifying harmful organisms, the
researchers also need to determine how to get the
most mileage from the units to maximize the number
of plant cycles produced from each module and
determine how future space explorers can effectively
and safely grow plants to help supplement their diets
on longer missions.
ASTRONAUTS ARE LIKELY TO BE VEGGETARRIANS
A round-trip to Mars will take more than a year and a
half, requiring more food than a spacecraft can hold.
Thus, space travelers are needed to 'create' food
source. Vegetables are the best candidates for feeding
astronauts because the seeds are easy to carry, can
be germinated in space, and then planted upon
reaching the surface of Mars.

astronauts because the seeds are easy to carry, can

reaching the surface of Mars. To solve pressure and
moisture issues, the first human visitors may grow
food inside spacious and lightweight, inflatable
greenhouses. Be careful, you may overheat your foods
easily, in the low pressure and gravity of Mars (reduced
air flow to cool the foods).
TOO EXPENSIVE TO HIRE A MAID IN MARS
Researchers are developing Robonauts, human-like
robots, to perform some tasks, e.g. the hand
tightening bolts during space structure assembly.
However, the Robonauts' "hands" had to be capable of
exerting just the right amount of force and control to
perform critical jobs.
CONTAMINATION OF WATER/AIR RECYCLE SYSTEM
WITH BACTERIA AND CHEMICAL
Space travelers sometimes spend months in the same
quarters, breathing recycled air and drinking recycled
water that makes the International Space Station and
space vehicles a potential breeding ground for bacteria
and gasses that build up over time.
Volatile organic compounds such as benzene, toluene,
ethylbenzene, xylene, dichloromethane and
formaldehyde, can get into a spaceship or station from
various routes. Space travelers cannot simply open the
spacecraft window to dissipate the gases. Thus, in
these volatile organic compounds present a health
hazard to them.
Researchers are engineering bacteria to produce light,
or luminescence, when exposed to toxic chemicals and
harmful bacteria.
