SEARCH FOR LIFE ON MARS : NASA

SEARCH  FOR LIFE ON MARS : NASA




The worlds newest island Hunga Tonga Hunga Ha'apai formed inlate 2024 or early 2015.
It rose from the sea bed due to volcanic eruption.
It was measured 1km wide 2 km long and 100m high
At remote Pacific  and is about 65 km northwest of the Tongan capital, Nuku'alofa.

NASA said this island can offer clues regarding the development of life on mars.
Mars had many similar volcanic islands which is surrounded by water at the time of its creation

Since it combined a wet environment with heat because of volcanic eruption, this sports may be the prime locations to look for the evidence of past life.


During the Volcanic eruption, warm sea water combined with ash to form tuff
Tuff is a  concrete like structure.


The erosion is significant and the island is expected to last between six to thirty years.

According to Jim Garvin ( Chief scientist , Goddard Space Flight Center )" Islands  like this might have worked on Mars two or three billion years ago- lakes and small seas filling depressions , persistent surface waters"

" It could have produced the conditions necessary for microbial life"

NASA's studies relating to this island was presented at a meeting by American Geophysical Union  in New Orleans
