Comet, Space

The scientist has said that they need more samples of comets so that they can understand the history of eh solar system. This was said by a researcher who has analysed the comet dust which was brought back to Earth by NASA’s Stardust mission in the year 2006.

The dust particles which are analysed by the researchers are of Comet 81P/Wild, and it contains the clues about the earliest history. The study was published in a paper during the last year whose title is “The future of Stardust Science” in the journal Meteoritics and Planetary Science. It has summarised about150 scientific publications which are based on Stardust mission science.

The asteroids which are represented in the collections by the meteorites and have been well documented for over the century and the moon material has been collected and brought to scientists to analyse the Apollo astronauts.

According to the Andrew Westphal, who is the senior member of the Stardust team and an astrophysicist at the University of California, Berkeley has asked investigators to seek out more Kuiper Belt material to study on Earth because of the unique origins. When you sample farther in the solar system, you need to sample the material which is more primitive, and it is needed when you get a sample from a comet, and you get a sample in the deep freeze for about 4.6 billion years.

Another important part of the study is about liquid water, and it is present in Wild 2. The investigators have looked even for phyllosilicates which have clays which have to preserve water inside them and the study of particles that have collected by Stardust have not yielded any phyllosilicates. The proposed Comet Astrobiology Exploration Sample Return (CAESAR) proves and it will be launched in the mid-2020, and it is specially designed to snag samples from the comet 67P and return with them to Earth.
