International Space Station: Beehive Of Man’s Activities In
Space II
The establishment of
International Space Station (ISS) took 12 years with major support from five
nations in addition eleven other nations who made different level of
contributions. US President Reagan was the brain behind ISS who then conceived
the idea of a relatively permanent space station in 1984 and directed NASA to
build it. At that time, many thought of the idea as braggadocio of American
leadership after her outstanding success of sending people to moon under the
Apollo 11 project fifteen years earlier.
No one could imagine the critical role a permanent space station could
play in human space exploration nearly four decades later. With American policy
of consistency and leading role, the International Space Station became a
reality and from November 2000 to date, the station has been continuously
populated with scientists of different nationalities experimenting different
theories and hypothesis.
As mentioned in the
first part of this piece, ISS is the ninth space station to be inhabited by human
crews, after the Soviet and Russian Salyut, Almaz and Mir stations as well as
Skylab from the US. The station is serviced
by a variety of visiting spacecraft: the Russian Soyuz and Progress, the US Dragon
and Cygnus, the Japanese H-II Transfer Vehicle, and the European Automated
Transfer Vehicle and the rest of other crafts coming and leaving the station
continuously. ISS is in deed a beehive of human activities in space. Now, what
are the successes achieved in ISS and the prospects as the world moves towards a
target year of 2028? The lifespan of ISS was initially planned to operate only
up to the year 2020, but in 2014 the US decided to extend its life to 2024.
Since then Russia has proposed to extend further the life of the ISS to 2028,
and the US space agency NASA seemed ready to accept this new extension. Prospectively,
it may reach a target of 2030. On the feats recorded in ISS, NASA alone has
catalogue of experiments, which will benefit from extension of the life of the
ISS for a few more years. For example, the Alpha Magnetic Spectrometer, NASA’s
particle physics detector, is researching “dark matter” using a setting that
would not be possible on the Earth’s surface.
There are colossal
achievements made in ISS by several nations from different continents of the
world. First, ISS provides to U.S. and her partners an operational outpost in space,
the most austere environment ever known in the history of humanity. Globally,
ISS serves as a platform where more than 2,400 experiments have been conducted
since it was first launched. ISS received more than 230 visitors from 18
countries in the last twenty years. In the August 2019 issue of online Journal
“ Scientific America 175” Christian Zur wrote article, which stated; “The
station's crew have logged over 1,300 extravehicular activity (EVA) hours on
more than 217 spacewalks”.
Few years back, Julie
Robinson, NASA Space Station program scientist presented ten top achievements
of ISS at the 64th International Astronautical Congress in Beijing, China. Among
the achievements were, the result of investigation the effects of the space
environment on the human body during long duration spaceflight. There is a considerable
loss of bone and muscle mass of the astronauts during space mission. Using ISS,
Astronauts are now able to address the bone loss that has historically
accompanied long periods of weightless.
Proper diet, including adequate amounts of vitamin D, and exercise are found
to be the solution. Resistive exercise,
like weight lifting on the Earth, is a recent addition and is now helping to
prevent a similar terrestrial ailment such as osteoporosis. Understanding the
metabolic processes that lead to osteoporosis and developing the medications
and therapies for prevention is a good feat.
Another accomplishment
is using optical instruments on the space station to assess water quality in
the world’s coastal bays. This was hitherto an impossible task due to large
volume of water and area coverage. In addition to this feat, there are a significant
number of instruments in Earth remote sensing and astrophysics that are
providing new access to data for various services on earth. This makes ISS to
be a significant platform for understanding of the Earth system and the
universe
Another breakthrough
is the study of Combustion engine in the space, the so-called “cold flame”.
Some of the research findings revealed more efficient ways of fuel consumption
in mechanical power generation engines using combustion system.
Again Studies in ISS
have shown increased virulence of bacteria in space. The findings point to
possible vaccines, perhaps one to combat salmonella, which is responsible for
15,000 hospitalizations and 400 deaths in the world annually. The activities in
ISS are inspiring, mobilizing and teaching students across globe about the
values of science, technology, engineering and math, or what famously referred
as the “STEM fields”. This way the Space station crews and other activities
have involved 63 million of the world’s students as at 2016 with additional 100s
thousands from then to date. Among these ISS educational activities, over 43
million students came from 49 countries across the globe. These educational
activities involved more than 28 million teachers located in different places
within the 49 countries.
Another very
important feat is research on “dark matter”, a substance that scientists are
just beginning to understand. As a substance, “dark matter” is believed to
account for approximately 85% of the matter in the universe and about a quarter
of its total energy density. In fact, the universe is made up of matters. In
ISS, there are series of studies of dark matter using the Alpha Magnetic
Spectrometer, an external observatory that was installed by space shuttle
astronauts in 2011. No doubt, the results of these studies will substantially
lead to discovery of mystery of space that is likely to advance the course of
mankind.
Studies on robot
technology are ongoing in ISS. There are improvements in robotics accomplished
with the station’s Canadian built robot arms that are leading to improvements
in brain surgery techniques. Another ongoing medical trial is “Microgravity
micro-encapsulation”. This is a scientific concept using the weightless
environment to develop drugs that can attack specific tumors with chemotherapy.
The global coverage
of satellites offers a unique, fact-based perspective that can help us overcome
our greatest challenges. Information from these spacecraft can help us improve
agricultural yields and protect habitat loss and stop deforestation. They
discovered the hole in the ozone layer and their data today remains key to
fighting climate change; and they’ve helped us to connect the world through Internet
and communication, an intangible service for millions. Satellites in space have
done much for us so far and, in the future, they will offer much more. With
access to the Internet comes increased knowledge sharing, the benefits of the
best doctors and teachers via tele-medicine and education, and greater
communication.
In conclusion, ISS
is presently serving many countries as a platform to make advancement in space
technology and thus, different nationals are assiduously and harmoniously working
in respective of their ideological lineage, religious or political differences.
As we move deep into 21st century, the economic, political and
military powers will depend on technological superiority of a nation. Nations
with less population and high technological advancement may have control over
countries with large population as long as such countries lag behind
technologically. The question is where is the place Africa particularly Nigeria
in this global rat race? Nigeria has
all it takes to build a sound technology to key into the global competition of
superiority. With more than 10 millions university graduates of science and
technology and over 200 research and development centers, it is just a matter
of political will, commitment and dedication on the part leaders and the nation
to make a giant step towards technological advancement. President Buhari has a
golden opportunity to kick-start this process. Time waits for nobody.
