Chris Herd, Artsci카지노 게임 컬렉션™97, is hoping to answer a fundamental question humanity has wondered for centuries: Is there life on other planets?
Herd, a planetary geologist and one of the world카지노 게임 컬렉션™s top experts on meteorites from Mars, is working with NASA on the Mars Perseverance rover, which landed on the red planet on Feb. 18 after a 470-million-kilometre journey. He is involved in collecting rock samples that will advance the project카지노 게임 컬렉션™s primary mission: to search for signs of microbial life.
카지노 게임 컬렉션śWhatever we find is going to have important implications,카지노 게임 컬렉션ť Herd says. 카지노 게임 컬렉션śIf we find evidence of ancient microbial life, it raises the possibility that life has risen on any number of those thousands of other planets around other stars that astronomers are finding all the time. If we don카지노 게임 컬렉션™t find life, it tells us that conditions had to be perfect and unique on Earth because life arose here and it카지노 게임 컬렉션™s rare anywhere else.카지노 게임 컬렉션ť
While scientists lack evidence of life on Mars, they do know there was water on Mars several billion years ago, which is key to supporting life. Jezero Crater, where Perseverance landed, is an ancient lake that contains a river delta. On Earth, rivers dump a lot of organic matter into deltas, making Jezero an ideal location for the rover to search for life.
카지노 게임 컬렉션śWe know Mars was habitable, but whether it was inhabited is the big question,카지노 게임 컬렉션ť he says.
Herd, a 카지노게임사이트 of Alberta geology professor and curator of the , joined NASA as a and is part of a group that will decide where the rover goes and when to take rock samples.
Perseverance has many instruments to explore the planet and has already sent the . But definitive proof about life on Mars is going to take a while. The rock samples collected by the rover won카지노 게임 컬렉션™t be back on Earth until 2031 at the earliest.
카지노 게임 컬렉션śThe conclusive evidence for life detection on Mars has to come from samples,카지노 게임 컬렉션ť says Herd, who studied geology at Queen카지노 게임 컬렉션™s. 카지노 게임 컬렉션śWe might get tantalizing hints from the rover, but we will have to take samples, seal them up, and make sure they come back to Earth.카지노 게임 컬렉션ť
Life on Mars isn카지노 게임 컬렉션™t the only mystery Herd is hoping will be solved. The project has the potential to give insight into how the planet was formed. Taking samples of a variety of rock types 카지노 게임 컬렉션“ igneous (formed from lava cooling) or sedimentary (formed by the deposition of minerals by wind or water) will reveal key details about how Mars카지노 게임 컬렉션™ geologic history, and how it went from a warmer, wetter planet to the dry, rusty desert today.
카지노 게임 컬렉션śIf we do a good job, the samples we get from this mission will revolutionize our understanding of Mars카지노 게임 컬렉션™ history,카지노 게임 컬렉션ť Herd says.
