Apollo 11: What next 50 Years of Man’s Terrestrial
Romance with Space? IV
The Challenger space
disaster of 1980s was among the most shocking calamities of the 20th
century. The challenger catastrophe was devastating to the entire humanity as
the event was watched live. The impact of the tragedy on the terrestrial space race
between the two giant countries (USA and USSR) was beyond imagination. Millions
of people horribly watched the video of the challenger tragedy live, through CNN
as the only international cable news station that covered the mission and aired
it live. The whole world was terrified watching and listening the commentaries
of the disaster as it happened when it did. Many schoolchildren were horrified
as they were among the watchers of the TV broadcast of the flight to cheer
their teacher who was among the crew when the incident happened.
The teacher, Christa
McAuliffe was among the seven Challenger crewmembers that was selected on July
19, 1985. She was the first NASA's educator astronaut under the agency's
Teacher in Space Project. McAuliffe, who was 37, taught social studies at
Concord High School in New Hampshire. As a civilian and teacher, McAuliffe
brought extra public interest and made the Challenger mission famous.
An intensive salvage
operation was quickly organized to retrieve the wreckage and the bodies of the
crew. The force of the explosion and altitude where the tragedy occurred complicated
the task of salvage operation. Eventually, the bodies of the seven crewmembers
and as much of the wreckage as possible were recovered and bodies were given
befitting burial. That was the end of the Challenger shuttle but not the end of
space exploration. No doubt, the challenger tragedy slowed down the progress of
man’s exploration of space but did not entirely stop it. What were or are the
advances in space exploration thereafter?
Instead of fear and jittery, space scientists went
back to drawing board and used the lessons from Challenger tragedy to advance
their course. Thus, there were several advances on space exploration leading to
technological revolution especially in communication industry.
Two years after the
Challenger disaster, several efforts were made including construction of NASA’s
international space station, a permanent facility in the Earth orbit. By middle
of August 1988, President Ronald Reagan announced that construction of a replacement
shuttle orbiter, named Endeavour was to begin immediately. When the shuttle service
resumed, however, it was no longer in the business of launching satellites for flying
people in space but was devoted exclusively to defense and scientific payloads.
The Reagan administration had been nursing the goal of stimulating a private
space launch industry, and now, with the removal of a heavily subsidized
competitor from the market, three different companies stepped forward within a
week’s time to announce plans for operating commercial versions satellite
shuttles. On launching satellite for communication, this column will feature
several breakthroughs made in communication satellites another time.
Nevertheless, in the
last 30 years, there were some exciting efforts in space exploration ranging
from “mission to mars” to the latest “mission to touch the sun”. These are
additions to the several launchings of satellite for communication, agriculture
and scientific advancements. On mission to mars, USA and USSR competed
fervently in sending satellites to Mars; some made several attempts and failed
before they eventually succeeded. The then USSR made multiple attempts in the
1960s to reach the Red Planet, which did NASA follow with its Mariner 3
spacecraft. Few of the failed missions can be cited.
In the month of
October, 1960, USSR launched two space crafts, Marsnik 1/Mars 1M No.1 (USSR)
and Marsnik 2/Mars 1M No. 2 (USSR) on 10th and 14th
October respectively with the intention of Mars flyby but the two space crafts
were individually exploded during the launch and failed to even reach the Earth
orbit. Ten days later, on Oct. 24, 1962: Sputnik 22 (USSR) was launched for another
Mars flyby. The rocket that launched the spacecraft had a fatal issue and the
spacecraft was destroyed soon after it achieved Earth orbit. Yet, another
attempt was made six days after on November 1, 1962 when Mars 1 (USSR) was launched
for an intended Mars flyby. The spacecraft made it to Earth orbit and beyond,
five months later, on March 21, 1963, when the spacecraft was 106 million km
away from the Earth, its radio failed and communication with the craft
permanently ceased. The launch of Mars 1
was immediately followed by launch of Sputnik 24 (USSR) on Nov. 4, 1962 for
another Mars flyby. Sputnik achieved Earth orbit but had a fatal issue when it
changed its trajectory toward Mars and it eventually fell back to Earth in
pieces.
Similarly, NASA also
experienced failed mission for an intended Mars flyby. On NASA launched Mariner
3 (US) on Nov. 5, 1964. After the launch, there was a problem, which could not
be fixed, thus, the mission failed.
While those first several missions didn't reach their target, NASA's
Mariner 4 finally did. The spacecraft launched on Nov. 28, 1964, and was the
first to fly by Mars on July 14, 1965. It sent 21 photos of the Red Planet back
to Earth.
NASA recorded
successes with launches of Mariners 6 and 7 in 1969, both of which reached Mars
and sent back a few dozen photos. These successes corrected the false first
impression of astronomers that Mars looked like the moon.
From 1970s to 2010s,
there were many breakthroughs in “mission to Mars” beyond the scope of this
column but the target is to accomplish manned mission to Mars by 2020s. As Scientists
are busy to reach this target, there are people with "crazy" idea of
not only to visit Mars but also colonize it and make it a second planet to be
occupied by man within the
next 40 to 100 years. A leading
personality in this crop of adventurers is Elon Musk, the Chief Executive
Officer of SpaceX. He has an estimated net worth of US$12.7 billion, making him
the 83rd wealthiest person in the world by the ranking of 2017. This column has
written on this subject in 2016 and 17, via www.breakthroughwithmkothman.blogspot.com
Beyond mission to
Mars, NASA launched “mission to touch the sun” on Sunday, 12 August 2018. To
“touch the sun” means for the first time, a NASA spacecraft will swoop in and
touch the sun. This spacecraft for the mission is named “Parker Solar Probe”.
It was launched to make 24 orbits of the sun before swooping into the outermost
part of the solar atmosphere, known as the corona, to study the sun up close
and personal. A jacket of gases called an atmosphere surrounds our Sun. The
corona is the outermost part of the Sun's atmosphere. There is a great mystery
beyond human comprehension about the corona. Although, the corona is far away
(millions of kilometers) from sun but it is much hotter than the surface of the
Sun. The surface of the Sun is about 10,000 degrees Fahrenheit, but the corona
can be as much as a hundred times hotter with temperatures of about a million
degrees. It's the most mysterious thing; it's like getting hotter as you walk
away from a blaze. Parker Probe is expected to bring information that could assist
in resolving this mystery. Parker has already spent one year in its about 3
years mission.
As I am concluding
this piece, India's spacecraft “Chandrayaan-2” launched a year ago reached moon
on September 6th 2019 and attempted to drop a lander named Vikram
near the lunar South Pole, but the mission controllers lost contact with the
descending craft when it was just 2.1 km above the gray dirt. The mission is
partially failing and is costing India about 140 million US Dollar.
The consistent
effort of NASA and other countries on space exploration are commendable and
sometimes sound bizarre, we must learn a lesson or two as Africans, we must
invest more in science and technology to be able to conquer hunger, poverty,
misery and bring hopes to the citizenry. It is the first thing that needs to be
done before development of spacecraft technology in Africa.
Well, cosmos and
space were divinely made beyond total human comprehension and thus, mankind
should limit his study of these perfect creatures to only those that can
benefit our planet, beyond this, it could be disastrous”- “kada muje mu nemo wata rigima” as famous Singer of Niger republic, Maman
Gawo of blessed memory said during the Apollo Mission 50 years ago.
