Poverty still rising all over the world, COVID-19 pandemic made it even worse. About 1.89 billion people, or nearly 36% of the world’s population, lived in extreme poverty. Nearly half the population in developing countries lived on less than $1.25 a day. Why should we spend money on space exploration when we already have so many problems here on Earth? Is it really that important? It’s like What if our ancestors thought that it would be a waste of time to figure out agriculture while we can do hunting? Or why should we spend so much time on exploring new lands while we have so many problems in our land? Each year, space exploration contributes to a lot of innovations on earth. It gave answers to many fundamental questions about our existence, and a lot of questions there to be answered if only we could increase our investment on space exploration. NASA’s annual budget is 23 billion dollars but, its only 0.1% of the total revenue. even if we were to increase the international budget 20 times it would only be a small fraction of GDP. isn’t our future worth a quarter of a percent?
Benefits of space exploration:
Improves our day to day life
Since 1969, Neil Armstrong became the first human to ever set foot on moon, our interest in science and technology has improved a lot. In 22nd February 1978, US space agency launched the first satellite for its program of global positioning system (GPS). Currently there are 31 global positioning system (GPS) satellites orbiting the earth.Space exploration helped us to create many inventions like television, camera phones, internet, laptops, LED’s, wireless gadgets, purifying system of water and many more that we are using in our day to day life. There are nearly 3,372 active satellites providing information on navigation, business & finance, weather, climate and environmental monitoring, communication and safety.
Improving health care
The international space station plays a vital role in health and medical advancements. The Astronauts who works on the ISS able to do experiments that aren’t possible on earth due to the difference in the gravity. The project of Exomedicine – the study of medicine and micro-gravity, gravity has an effect on a molecular level so working in an environment where it can be eliminated from the equation allows discoveries that would otherwise be impossible. Medical advancements due to space exploration include,
- Diagnosis, treatment, and prevention of cardiovascular diseases
- Treatment of chronic metabolic disorders
- Better understanding of osteoporosis
- Improvements in Breast cancer detection
- Programmable pacemakers
- Laser angioplasty
- NASA’s device with Space technology for Asthma
- ISS plays vital role in vaccine development
- Early detection of immune changes prevents shingles
- Development of MRI s and CT or CAT Scans
- And invention of ear thermometers
Need for space colonization
Overpopulation is one of the major crises in our planet. Currently we have 7.8 billion people alive on earth. Experts predict that there will be 9.7 billion people by 2050 and 11 billion by 2100, our earth can carry only 9 billion to 12 billion people with the limited food and freshwater resources. That means we have to find an exoplanet with suitable conditions soon. We already went to moon 6 times, we already sent a rover to Mars. Robotic missions are cost efficient, but if one is considering the future of human race we have to go there ourselves. Elon Musk announced that SpaceX is going to send people to Mars I 2022. NASA planned to make a colony on Mars by 2030. These missions are not something we need at this moment. But it may play an important role on our future. Proxima Centauri b is an exoplanet which is 4.24 light years away from us. With our current technology, it is impossible to reach it in our lifetime. But we should make it as an aim for interstellar travel over the next 200 to 500 years. Stephen hawking said that the human race has existed as a separate species for about 2 million years. Civilization began about 10,000 years ago, and the rate of development has been steadily increasing. If the human race is to continue for another million years, we will have to boldly go where no one has gone before.
The day we stop exploring is the day we commit ourselves to live in a stagnant world, devoid of curiosity, empty of dreams. –Neil deGrasse Tyson
