Why Tardigrades are one of the most toughest micro-animal in the world??

We all know about Israel's mission to moon named Beresheet.

Mission which was launched with help of SpaceX rocket Falcon 9 B-5.

Unfortunately it crash landed on moon and they loose contact to there lander.

But one interesting thing about this mission was that, this mission was also carrying Tardigrades.

So Let us know what are these creatures and how much tough they are :



  1. They were first described by German Zoologist Johann August Ephraim Goeze in 1773 who called them little water bears.                                                                                                           
  2. There official name was given by Italian biologist Lazzaro Spallanzani which is Tardigrada .Tardigrades are also called as water bears or moss piglets.                                         
  3. These tiny little creatures are of half millimeter of size, 5 times the diameter of human hair.         
  4. Tardigrades are 8 legged water dweller belongs to kingdom animalia.
  5. These animals are capable to withstand extreme temperature and pressure. Pressure 6 times higher then Mariana trench(30, 000 feet below sea level).

  6. Tardigrades are found in most torturous environment which can kill almost any living being like inside volcano, in arctic ice and in deepest point in the ocean.

  7. Tardigrades survived 5 mass extensions and they are hear on earth for around 500 million years.

  8. In 2007 when a research team took them to space.You will be surprised to know that they managed to survive in vacuum and direct solar radiation for 10 full days.                                   
  9. Tardigrades can live there normal life and have reproduction even in - 20 degree temperature !!

  10. They can withstand 1000 times more radiation than humans.

So from where do they get these superpowers which make them indestructible??


Tardigrades when subjected to harsh condition like in space they turn into a ball like structure which is called "tun" by releasing all the water present in there body.

Which is called Cryptobiosis in scientific term.

For surviving extreme temperatures they take the help of there sugary gel which cover there entire body.
Which is called Trehalose in scientific term.

Tardigrades can survive in this ball like formation for decades.

It is for sure that they will not able to last for long on moon but yeah, they are now the first species to colonize the moon for a while.

But scientists are still searching what these Tardigrades can actually do, may be they find another source to live on moon.

What do you think ,let me know down in comment section.

Is ISRO in a position to compete with the space organizations of other countries? Where does it rank?

ISRO is one of the biggest contender in space race despite limitations on funding and resources. Many milestones achieved by ISRO like Mars Orbiter Mission, Chandrayaan, 104 satellite launched in orbit on a single rocket put them in the forefront of space race. ISRO might have very less funding in comparison to other major space agency like NASA,JAXA,ROSCOSMOS, ESA, CNSA, CSA but determination of space scientists and there hardwork put ISRO in above elite space groups. There is no ranking system but if I would like to give ISRO a rank and on which most of the people will believe is: 1.NASA 2 ROSCOSMOS 3.CNSA 4.ESA 5.JAXA and ISRO 6.CSA

How Parker Solar Probe will withstand Sun's heat ?

Sun may look calm and beautiful from our earth but it is one of the most ferocious body in our solar system, a body whose mass continuously rises ,  having millions of nuclear reactions going every second , tingling magnetic lines sun also have strong and constant winds flowing with speed of million miles per hour . Since it is the only star in our reach to study but it is still very difficult to study its behaviour So how? Parker Solar Probe The answer is Parker solar probe made by NASA which will blast off this year to a long journey of around 4 million miles(6.4 million km) from the earth to the sun. The temperature of sun which can rise up to 1 million degree Fahrenheit is strong enough to melt anything approaching it. So how will our small probe will withstand this harsh surrounding? But still the temperature of the solar panels and elements still can go to about 2498 degree Fahrenheit (1370 degree Celsius) so there is necessity to co...

NASA's Chandra X-ray observatory may have observed star consuming a planet for the first time

There are infinite number of stars in our universe. It is always remained an attraction for cosmologist to observe there behaviour. Many observatories are made by space agencies to study astrology and cosmology one of them is NASA's Chandra X-ray observatory  It is dedicated in observing behaviour of stars and planets in  our galaxy  there are many evidence which shows that a star can consume planets. Well,The New report from NASA on findings of  NASA's Chandra X-ray observatory which says that they have observe a star in our Milky Way Galaxy around 450 light years away from our earth. the star which which is named RW Aur A is been in consideration of scientist since 1937 . the curiosity in this star increased due to fading of its optical light for few decades and brightening again.  But in recent times the frequent dimming of light took attention of scientists A team of scientist with  NASA's Chandra X-ray observatory  obse...
