A small step for ISRO, a giant leap for building consensus around space exploration in India.
Humans have looked up at the stars even before language was invented, and the lights above us have always been a part of human imagination and curiosity, be it in religion, philosophy, science or the arts. What changed in the last century is that not only could we look up, but humanity got the ability to go up high and look down. The photograph Earthrise by astronaut William Anders is easily among the most iconic images to date, where a blue earth rises above the scarred lunar surface.
Exploration in general and space exploration in particular has always excited and inspired people in a manner that few other ideas could. Organisations like NASA figured out early on that beyond any scientific or utilitarian purposes, beautiful images from space have immense value in and of themselves. With human spaceflight, astronauts could take photographs manually. But with improvements in photography, image processing and visualisation technologies, even satellite images can now have great aesthetic and communicative value.
Anyone who has glanced at Google Earth or seen any of NASA Earth Observatory’s exquisite pictures already knows the value of visually observing the earth from space.
ISRO and the Indian space programme has been quite slow in realising the same and acting on it. Though India has been sending satellites to space for over three decades now, there are hardly any memorable images one can think of. Rakesh Sharma in his cosmonaut comes to mind, and the other is of space launches. Little from the satellites themselves. While several Indian satellites have imaging capabilities of various kinds, they have been put mainly to technical and scientific uses and almost never for public consumption.
India’s Mission to Mars providing the above simple and elegant image of the Indian subcontinent is the latest step in establishing a culture of communicating with the public on the national space programme. Compared to NASA’s high quality, you can see that the image is far from perfect – the clouds are overexposed, the image has been rotated and cropped, and resolution is sub-optimal. But instead of descending into snobbery, we really need to appreciate the increasing effort ISRO is putting in doing this. Earlier in the year ISRO provided some stunning images of the Kumbh mela and the disaster at Kedarnath. Nothing illustrates the changing mindsets at ISRO better than the contrast of these examples to the best photograph of the earth from Chandrayaan – shared below.
Space exploration is a very public affair – for better and for worse. It is exceedingly difficult to hide success or failure from the public eye, and one has to constantly address questions of poverty while spending public monies on space. Visually engaging the public is essential if ISRO wants to think bolder, aim higher and go farther. One picture from above can help people understand floods or urban growth or complex natural phenomena like no amount of explaining can.
The good news is that NASA has already paved the way for ISRO, and they could also possibly help the latter in setting up a team in-house which can work on a visual exploration of India from space. Below are a curated set of images of India from space, taken by various NASA spacecraft and satellites. Here’s to hoping that their tribe grows larger.
