The Perseverance rover, the core of the $2.7-billion Mars 2020 mission of NASA, is slated to land on February 18, kicking off a new Red Planet exploration era.
Mars was thought of as a dead planet during the 1960s and 1970s but the Marsquakes and landslides observed in the later years have proven that it is still an active planet.
Presently, it appears like only a matter of time before humans approach Mars. However, to get there, there are some dangers for humans to be familiar with and overcome first before the trip to Mars.
During their meeting, the research team reported that InSight had detected almost 500 small 'marsquakes,' although only a few with a magnitude higher than 4.5, said Paul Voosen.
On the night of October 13, the Earth and Mars will line up with the New Moon in an event called 'opposition' in which the Mars and the Sun are in opposite sides of the Earth.
Planetary scientists and artificial intelligence (AI) researchers have collaborated on a machine learning tool that helped discover new craters on Mars - including small impacts left by a meteor about eight years ago.
Chitin, an organic substance commonly found on Earth, can be used to create tools and shelter for future space explorations on the Moon and on Mars. Scientists have been developing technology that efficiently manufactures chitin-derived materials.
