Top 10+ Space Research Organisations in the World

Space Research (or sometimes called space exploration) is the scientific studies on earth’s outer space which involves advance material science, earth science, physics, mathematics, medicines and biology.
There are numerous space organisations working on our planet to explore and find out the mysterious matters present in our space. Each organisation has certain rules and policies regarding their capacity to develop and money spend per year on each space research project.
Most of them uses the far advanced tools and technology that has been not used for public yet. In order to find out more lets take a look at the list of top 10 Space Research Organisations in the world

SpaceX
SpaceX is the first successful private space company, founded by Elon Musk in 2002. The company has recently gained a lot of popularity because of its low-cost rocket launch (making rockets reusable) and mars mission.
Since it’s a private company, their mode of funding, availability of resources, and ultimately their goals are different than other space organisations. When it comes to building satellites, SpaceX scores zero because they haven’t built any yet, and that is not even their objective.
Their primary aim is to reduce space transportation costs and enable the colonization of Mars. They have built the Falcon launch vehicle family and Dragon rocket-family, which both currently deliver payloads into Earth orbit. They are also trying very hard to send the first human to Mars by 2024.
Achievements till date:
  • First privately funded liquid propellant rocket (Falcon 1) reached orbit in 2008
  • First private company to send spacecraft to the ISS (Dragon in 2012)
  • First propulsive landing for an orbital rocket (Falcon 9 in 2015)
  • First successful reuse of an orbital rocket (Falcon 9 in 2017)
In 2017, SpaceX has been contracted by 2 private individuals to send them in Dragon on free return trajectory around the Moon. This might become the first lunar tourism by the end of 2018.

Negative Population Growth

Cute babies crawling


Data from the Population Reference Bureau showed in 2006 that there were 20 countries in the world with negative or zero natural population growth expected between 2006 and 2050. 

What Does Negative Natural Population Growth Mean?

This negative or zero natural population growth means that these countries have more deaths than births or an even number of deaths and births; this figure does not include the effects of immigration or emigration.
Even including immigration over emigration, only one of the 20 countries (Austria) was expected to grow between 2006 and 2050, though the rush of emigration from wars in the Middle East (especially Syria's civil war) and Africa in the mid-2010s could revise those expectations.

The Highest Decreases

The country with the highest decrease in the natural birthrate was Ukraine, with a natural decrease of 0.8 percent each year. Ukraine was expected to lose 28 percent of its population between 2006 and 2050 (from 46.8 million to 33.4 million in 2050).
Russia and Belarus followed close behind at a 0.6 percent natural decrease, and Russia was expected to lose 22 percent of its population by 2050, which would be a loss of more than 30 million people (from 142.3 million in 2006 to 110.3 million in 2050).
Japan was the only non-European country in the list, though China joined it after the list was released and had a lower-than-replacement birthrate in the mid-2010s.
 Japan has a 0 percent natural birth increase and was expected to lose 21 percent of its population between 2006 and 2050 (shrinking from 127.8 million to a mere 100.6 million in 2050). 

A List of Countries With Negative Natural Increase

Here's the list of the countries that were expected to have a negative natural increase or zero increase in population between 2006 and 2050.
Ukraine: 0.8% natural decrease annually; 28% total population decrease by 2050
Russia: -0.6%; -22%
Belarus: -0.6%; -12%
Bulgaria: -0.5%; -34%
Latvia: -0.5%; -23%
Lithuania: -0.4%; -15%
Hungary: -0.3%; -11%
Romania: -0.2%; -29%
Estonia: -0.2%; -23%
Moldova: -0.2%; -21%
Croatia: -0.2%; -14%
Germany: -0.2%; -9%
Czech Republic: -0.1%; -8%
Japan: 0%; -21%
Poland: 0%; -17%
Slovakia: 0%; -12%
Austria: 0%; 8% increase
Italy: 0%; -5%
Slovenia: 0%; -5%
Greece: 0%; -4%
In 2017, the Population Reference Bureau released a fact sheet showing that the top five countries expected to lose population between then and 2050 were:
China: -44.3%
Japan: -24.8%
Ukraine: -8.8%
Poland: -5.8%
Romania: -5.7%
Thailand: -3.5%
Italy: -3%
South Korea: -2.2%

Countries With The Highest Population Growth

Countries With the Highest Population Growth
A greater numbers of births than deaths results in what is known as “natural” growth. Such growth is affected by factors such as war and contraceptive measures, the distribution of the population among age groups, and life expectancy at birth. Immigration and emigration are also significant contributors to the population changes within a country as well.
Recent data shows that Oman has experienced a growth rate of 8.45% in recent years. This rate of growth positioned this Middle Eastern country within the top spot globally in terms of possessing the fastest population growth rate among any nation that year.
Currently, the world’s population totals an estimated 7 billion-plus people, with more than half of that population residing on the continent of Asia. Another quarter of the population inhabits the continent of Africa, where the African nations of South Sudan and Niger experienced a growth rate of 4.09 and 4.00, respectively. The population growth within the two continents has been a consequence of concurrent rise in the median age of the population, declines in infant and total mortality rates, and high fertility rates which, although declining, are still far above the replacement rate in many of these areas.
According to most likely scenarios forecast by projections from the UN and other international organizations compiling demographic statistics, the world’s population will increase by around an astounding 4 billion inhabitants between now and the welcoming of the year 2100. This growth is said to be a result of people living longer, and healthier lives amidst improved living conditions. Today, three of the five most populous countries in the world can be found within Asia, with India projected to surpass China as the most populous country in the not-too-distant future.
The country rounding out our top 20 is Mali, who reported a growth rate of 2.98%. The second fastest growing population globally, residing within the country of Lebanon, registered an estimated growth of 5.99%. Most people assumed that the United States would have been among the countries at the top of the list in regards to population growth, but in actuality it is not within the top 10 at all. Experts believe that this is due in part to the abundance of contraceptive options available within the country, changes in migratory trends in and out of the nation, and increased education opportunities for women, when traditionally has coincided with reduced birth rates.
