“I believe the effort to instil within students love for science needs to start at the early stages of education.”
Since I used to be a baby, I’ve been fascinated by the alluring evening sky, the glittering moon and numerous stars over the horizon. All all through my childhood, house sciences and astronomy remained my ardour.
While researching personalities from all around the globe in these fields, I all the time questioned why regardless of the very fact there isn’t any dearth of expertise within the nation, I used to be unable to seek out any occasion of Pakistanis working for the National Air and Space Administration (NASA).
I obtained in contact with Dr Mohsin Siddique, director of the theoretical physics division on the National Center for Physics, Islamabad.
Through him I had the privilege of connecting with Mr Mansoor Ahmed, a Pakistani astrophysicist, who has been related to NASA for nearly 35 years and is at present serving because the affiliate director of the Astrophysics Projects Division, in addition to the programme supervisor for the Physics of the Cosmos programme and the Cosmic Origins programme at NASA Goddard Space Flight Center, Maryland.
Mr Ahmed has spent most of his profession working on the Hubble Space Telescope (HST) programme in several capacities, together with as flight operations supervisor and the venture supervisor for HST operations.
He was the deputy venture supervisor of the James Web Space Telescope (JWST) and because the venture supervisor of the Laser Interferometer Space Antenna (LISA) mission, a collaborative endeavour between NASA and the European Space Agency.
Here, I ask the spectacular gentleman his success story, from his childhood in Peshawar to his work with NASA.
You had been born and grew up in Peshawar. Can you inform us your loved ones background? Do you recall any fascinating story out of your childhood/teenage years?
My father was a Subedar-major within the military. We lived in Peshawar, close to Fort Bala Hissar.
For the primary 5 years of my training, I went to a Christian mission college and from sixth grade onwards, I attended the Government Higher Secondary School.
My father took me to see The Vikings and I used to be hooked from then on, regardless that, I didn’t actually perceive any English at the moment.
My reply to the query ‘What do you need to be whenever you develop up?’ was: “I need to develop into the ticket collector at Naaz cinema in order that I can see each movie taking part in there.”
After watching a movie, I might inform the story, scene by scene, intimately to my cousins. I assume that’s the place I picked up the artwork of storytelling that’s coming in helpful now in my filmmaking endeavour.
One day, I used to be visiting some family members who lived proper subsequent to the Pakistan Air Force base in Peshawar and I witnessed an F-86 land on the runway. As the airplane taxied, I might see the cockpit and the pilot.
The pilot waved at me as he handed by and proper then my profession targets modified. I needed to be a fighter pilot.
At Government High School, an in depth buddy of mine, Ayub, instructed me concerning the Air Force cadet academy in Lower Topa, a tiny city close to Murree.
It consists of a boarding college that selects 60 youngsters every year as pre-cadets, to organize them to enter the air pressure flying academy after FSc. Ayub stated he was making use of and inspired me to the identical.
Fortunately, each of us obtained chosen and we entered Lower Topa in May of 1966, on the age of 13.
In Pakistan it isn’t widespread for fogeys to assist their children to pursue astronomy as a occupation. Can you inform us how a lot encouragement you obtained from your loved ones through the early years of your profession? Would you encourage your personal youngster in the event that they had been to want the identical occupation?
I feel there are two features to this query. Parents are involved concerning the livelihood of their youngsters after they develop up.
They are involved whether or not their youngsters will have the ability to earn a residing and assist a household. So, their tendency is to push their children in direction of careers which are identified to offer a very good residing.
Unfortunately, most frequently their preferences are additionally tainted by the obvious standing of sure careers in our society. They find yourself ignoring the pursuits and aptitudes of their youngsters in areas that won’t rank excessive within the standing hierarchy in Pakistan.
It could be very doubtless that if allowed to pursue their very own pursuits, youngsters would actually thrive in any profession selection they make, whether or not it’s engineering, medication, music, enterprise, sports activities, and so on.
All images by Mr Ahmed.
Taking astronomy for example, regardless that there is probably not too many job alternatives in astronomy in Pakistan, if a baby is genuinely and has the suitable aptitude within the topic, encouraging them to pursue their ardour could lead to an illustrious profession which may reply probably the most profound mysteries of the universe, presumably getting worldwide recognition.
I recognise it’s a robust selection for fogeys, particularly in Pakistan, the place there’s a stigma connected to sure careers and that are usually discouraged.
In my scenario, I’m not certain if my dad and mom would have inspired me to develop into a ticket collector at Naaz cinema however they undoubtedly didn’t cease me from pursuing a profession within the air pressure.
In the case of my youngsters, I imagine in permitting them to pursue their passions, be it astronomy, plumbing, or driving a taxi.
It is simple for me to say so as a result of within the US, there may be usually no stigma connected to any profession and an individual could make a good residing in any job, so long as they’re keen to work exhausting for it. And if one has a profession which follows their ardour, it’s straightforward to place one’s again into it.
The common particular person in Pakistan isn’t conversant in even primary scientific information and curiosity in pursuing a profession within the discipline of science is usually low. How do you assume this case might be addressed?
I imagine the trouble to instil inside college students a love for science wants to begin on the very early levels of training. Children have a a lot larger curiosity and open minds than adults.
As we get older, our views get narrower and biased. We have to design science curriculums in a method that’s partaking and simple to know on the elementary degree.
More emphasis ought to be positioned on hands-on workouts and demonstrations, and never on memorisation of fabric. For this to happen, we have to prepare academics on how you can current the knowledge in an fascinating method.
I additionally really feel that we separate science and humanities college students too early on within the levels of their academic improvement. Science programs ought to be made obligatory for an extended interval – maybe till the 12th yr of training.
To additional inspire younger college students into hopping onto the science and technical tracks, colleges ought to encourage distinguished scientists, engineers and technically-oriented professionals to go to and provides talks about their fascinating careers.
You have a bachelor’s diploma from University of Maryland and a grasp’s diploma from George Washington University in mechanical engineering. If you may do it once more, would you are taking a unique tutorial path?
This is a really fascinating query to reply. First, I need to admit, there isn’t any direct path connecting my present profession at NASA to my academic targets after I was a pupil.
As I discussed earlier, my profession purpose was to develop into a fighter pilot. I used to be fortunately pursuing it in Lower Topa after I turned unfit for flying as a result of my weak eyesight.
My dad and mom had already migrated to the US whereas I used to be nonetheless in Lower Topa, and as soon as unfit to fly, I used to be given the choice to affix my dad and mom there. I exercised this selection.
When deciding my academic path, I used to be nonetheless pushed by the love of flying and figured I ought to examine aeronautical engineering in order that I can nonetheless work with jet planes.
As I began my bachelor’s diploma, it turned obvious that job alternatives in aeronautical and aerospace engineering had been diminishing. The Apollo Program was coming to an finish and there was no actual imaginative and prescient that NASA was pursuing.
So my advisor really useful that I alter my main to mechanical engineering. Out of all my programs, I loved thermodynamics and warmth switch probably the most.
The US was getting into a interval of vitality disaster and the federal government was specializing in commercialising alternate, renewable vitality assets, reminiscent of photo voltaic and wind vitality.
These wants had been consistent with my tutorial coaching and I used to be inspired to proceed my grasp’s diploma within the space of vitality assets. As luck would have it, NASA was in want of somebody with warmth switch experience, which opened the door for me into the organisation.
The level I’m attempting to make is that, the place I’m right this moment is due to the circumstances that ended up in my favour. There had been a number of events the place I might have made completely different selections and pursued a course of research leading to a unique profession.
Who is aware of if that profession would have been as thrilling because the one I’ve now. So personally, I might not need to return to my pupil days with the chance of not ending up the place I’m right this moment.
You have spent most of your profession working for the HST programme. Can you inform us what makes the Hubble Telescope so unimaginable?
Hubble isn’t solely a scientific marvel however an engineering one as nicely. The thought of placing a telescope in house was a masterstroke.
Even although we have now telescopes on the bottom, they endure from a number of limitations. They can solely observe at evening and for a comparatively quick length till the solar rises once more.
Our environment additionally limits the wavelengths of sunshine that the ground-based telescopes observe. With Hubble being above our environment, it could see way more clearly and isn’t restricted by the day-night cycle.
All the celebrities we see in our evening sky with the bare eye all belong to our galaxy, Milky Way. Other galaxies are a lot farther away and the sunshine coming from them is extraordinarily dim.
To take their photos, Hubble should keep pointed on the distant galaxies for a very long time.
You can examine this to taking an image at nighttime with no flash. You should preserve the digital camera shutter open for a very long time, protecting the digital camera completely nonetheless or the image will probably be blurry.
Hubble can keep pointed at an object billions and billions of miles away for days, whereas travelling across the earth’s orbit at 18,000 miles per hour. Over the interval of the commentary, it doesn’t jitter greater than zero.000002 levels.
These are a few of the engineering capabilities that permit Hubble to unearth the wonderful scientific discoveries that it has.
Do you have got a favorite science outcome that got here from Hubble, particularly contemplating the truth that you have got been an energetic a part of the Hubble restore mission?
It could be very troublesome to slender down probably the most favorite outcome from Hubble; there are such a lot of stunning photos of exploding stars and merging galaxies that everybody can be amazed by.
The most profound picture in my thoughts is the Hubble Deep Field picture. We determined to level Hubble to a tiny, seemingly darkish spot within the sky the place there was nothing the bare eye might see.
Hubble stayed at that spot for 11 days, capturing any photons which may come from that route to assemble the ultimate image (keep in mind my instance of taking a photograph at nighttime).
When accomplished, it was wonderful to see that the image was filled with vivid objects, 1000’s of them. Each certainly one of them was a galaxy consisting of trillions of stars.
That picture illustrates how huge our universe is and makes one marvel our significance (or insignificance) on this universe.
The different nice discovery, which is scientifically probably the most vital, is that of darkish vitality. Before Hubble was launched, the largest query in astrophysics revolved across the destiny of the universe.
Will it proceed to develop due to the preliminary pressure of the Big Bang or will it decelerate and begin contracting because of the gravitational pull of the matter within the universe?
What our universe will do will depend on the overall mass within the universe, which defines the gravitational pressure within the system. Sir Edwin Hubble (whom the telescope is called after) decided the essential worth of the mass (generally known as the Hubble Constant) that will outline the destiny of the universe.
If the mass is lower than that worth, then the universe will proceed to develop, ultimately cooling off and dying. If the mass is greater than the worth, then the universe will decelerate, begin contracting and find yourself as a singularity leading to yet one more massive bang, with this cycle persevering with without end.
One of the first aims of Hubble (the telescope) was to find out the Hubble Constant. Instead, what Hubble found was that the universe is neither slowing down or increasing at a continuing velocity, however just a few billion years in the past, had began to develop quicker than earlier than.
This can solely occur if there may be some type of vitality that appeared from someplace, and is making the universe develop quicker (Newton’s first legislation of movement). We name it darkish vitality as a result of we have now no clue what it’s.
Solving the darkish vitality thriller has now develop into one of many high questions in astrophysics.
The JWST is an infrared telescope whereas Hubble is an optical telescope. Having additionally served as a deputy supervisor for the JWST, how do you are feeling about the way forward for Hubble? Is it true that JWST enjoys larger significance than Hubble?
Hubble and JWST are equally necessary instruments for answering the astrophysics questions. Just like Hubble can’t see infrared mild, JWST can’t see optical and ultraviolet mild.
Together, they’ll resolve extra mysteries than both one can by itself. Hubble continues to be in excellent well being. We predict that each one its programs will nonetheless be purposeful till 2022 and almost certainly past.
JWST will launch in early 2019. The scientific neighborhood is eagerly awaiting when each of those observatories will work hand in hand.
What are you able to inform us about LISA? What do gravitational waves inform us and the way would LISA additional our data concerning the starting, evolution and construction of the universe?
Up till now, all of our astrophysical discoveries have been finished by analysing the electromagnetic spectrum. The seen mild, which the human eye can see, and Hubble is optimised for, is only a small subset of this spectrum.
The spectrum ranges from radio waves at one finish and really energetic gamma rays on the opposite. We have satellites in house observing most of those wavelengths and collectively they’ve knowledgeable our data of the universe to this point.
But the electromagnetic spectrum is generated by the celebrities when they’re born and begin to emit electromagnetic radiation.
There had been no stars on the time of the Big Bang, solely elementary particles that coalesced collectively to kind electrons and protons, which in flip fashioned hydrogen.
The hydrogen atoms began to coalesce to kind blobs of hydrogen, ultimately forming a mass giant sufficient to have sufficient gravitational pressure to provoke hydrogen fusion on the core of this blob, thus igniting the blob into changing into a star that began to emit electromagnetic waves.
This course of took a whole bunch of 1000’s of years. So, there have been no electromagnetic waves throughout this time.
We name it the darkish interval as a result of there was no mild, and because of this, we are able to solely predict theoretically what occurred throughout that interval.
Gravitational waves then again had been generated proper firstly of the Big Bang as a result of mass all the time existed and mass creates gravity.
The LISA mission is being designed in order that we are able to see the universe with gravitational waves; a very new method of wanting on the universe.
With LISA, we will take a look at the darkish interval from the very starting of the Big Bang. We would additionally have the ability to see deep inside black holes from the place electromagnetic mild can’t escape.
While we’re within the technique of constructing LISA, there are a number of ground-based gravitational observatories coming into motion already.
You visited Pakistan final yr and spoke on the National Center for Physics, Islamabad. What did you observe?
I had the privilege of assembly younger college students in a number of establishments in Pakistan. I need to say I used to be very impressed by their curiosity, intelligence and curiosity in astronomy and astrophysics, even with the restricted assets accessible to them.
I used to be very inspired to see that there have been nearly an equal variety of women and boys attending the talks. A variety of them had been enrolled in PhD programmes in physics, which isn’t a simple topic.
I’ve made commitments to the management of those establishments that I’ll do my finest in connecting these college students with scientists and engineers at NASA who can present them steerage in pursuing careers in space-based astronomy.
I’ve already obtained commitments from NASA scientists to present periodic lectures on-line to the college students in Pakistan.
