Why NASA chose Senegal to control the frozen world outside Pluto?


MU69 is a peaceful form of the Kuiper belt (informal Ultima Thule) discovered by Hubble Space Telescope in June 2014.

NASA tries to find out more about this facility starting our solar system.

Senegal was chosen to observe this occultism because of its political stability and the presence of amateur astronomers and scientists.

The choice of Senegal was made in August (rainy season) in spite of complex climatic conditions, suggesting that only 50% would succeed.

The NASA-sponsored competition, organized jointly with Senegal, will provide valuable data for the preparation of the MU69 New Horizon spacecraft, which will be held on 1 January 2019. It helps to verify its shape, speed and location.

This information is intended to be used successfully for smaller objects within a distance of one billion miles.

The most distant world has been studied

MU69 is 6.5 billion km from the sun. It is the most distant and simplest world studied the spacecraft. NASA's New Horizons team, after successfully mastering Pluto and its months in July 2015, decided to expand the mission.

Taking into account the possibilities offered by the current horizons of the new Horizons zone, MU69 was selected as the next destination in the immediate vicinity. To collect data for this object, the New Horizons team used starred occult in Argentina and South Africa on July 3, 2017.

The findings of these observations suggest that the object can consist of two forms that have an extended form or to be transformed into one another.

In August 2018, about 21 Senegal scientists took part in the preparation and selection of localities in the region, ranging from Thiesen to St. Louis.

They set up observation sites and decided that NASA's participants should be able to reach observation areas, especially in the countryside, in the evening. Subsequently, Senegal scientists learned to work full hours of control using telescopes and accumulation systems.

The purpose of the training is to install telescopes and accumulators, to guide the telescope to the hidden initiative and to obtain the data from 10 to 20 minutes.

Each team consisted of one Senegal scholar (post-graduate, doctoral or professor) and two astronomers from NASA or France (who participated in French experimental scientists).

During the occult occurrence in Senegal, we collected data using 21 telescopes of various sites. These data are photometric measurements, which accurately records the time when the MU69 passes through the star and blocks its light.

Because of a rainy season in Senegal, we were unable to collect all 21 site data. All three sites have purchased useful data.

But during the night of darkness, despite the weather, we observed occultation.

The appearance of the solar system

Astronomy in Senegal is not taught at university level. However, the Senegal Government is building a planetarium and an astronomical observatory.

For your new generation, Senegal would like to focus on available equipment, expertise and research tools.

This is the control of meteorroids on moon or giant planets, exploring starvation stars, looking for exoplanet controls or controlling the planet's atmosphere.

The MU69 study with the New Horizons allows us to learn more about the start of our solar system.

The plane opens an unknown world. As for Pluto, this knowledge of the object varies from "small points" to high resolution images of mysterious landscapes.

Data collected from competitions will help you improve the preparation for the most remote planet meeting in history.
As a result of Pluto's new horizons, Pluto's recent geological activity, the 1000-kilometer-long heartbeat of the nitrogen glacier in the solar system, and its blue color was one of the top 10 most unexpected discoveries. Who can say what happens to MU69?
The prospects of this cooperation are in our hands through the development of scientific projects in our country and at the African level, for example, by supporting Africa's initiatives for the planet and space science, and through the connections with NASA scientists.

Ideas such as organizing a future workshop of planetary atmosphere have been raised. We will learn a lot from comparing our planet with other planets, and this workshop on the planetary atmosphere in Senegal will have a real meaning in the context of climate change.
