MU69 is a frozen object of the Belt Belt (informally named Ultima Thule) which was discovered in June 2014 with Thelescope Space Hubble.
NASA pursues this object to learn more about the origin of our solar system.
Senegal was chosen to observe this occult, due to its political stability, and the existence of a society of astronomers and amateur scientists.
The choice of Senegal was made despite the challenging climatic conditions in August (rainy season), which offered the likelihood of success only 50%.
This information is essential in order to make a small aspect of a small object at a mile mile distance away from us.
Most of the far world have ever explored
MU69 is about 6.5 billion kilometers away from the sun. This is the most remote and most primitive world ever explored by space space. The team decided behind NASA's New Horizons, following a successful investigation of the Pluto and herbs plant in July 2015, further extending the mission.
Given the possibilities offered by the current horizon of the New Horizons auditor, MU69 was selected as the next target for close flight. To collect data for this object, the New Horizons team benefited from representation on July 3, 2017, to see in Argentina and South Africa.
The results of these comments suggest that the object has a long shape or it may contain two objects that rotate each other.
For the observation in August 2018, some 21 Senegal scientists were actively involved in the process of preparing by choosing possible location sites throughout the country in a stretching region from Thiès to Saint Louis.
They marked the observation sites, and this work was crucial as NASA participants have to reach observation sites, often in rural areas, during the night. Then Senegal's scientists were trained to use the telescope and procurement systems, to be fully active during an observation night.
The aim of the training was the ability to install the telescope and the procurement system, place the telescope to the hidden scene of the hidden start and acquire data for 10 to 20 minutes.
Each team consisted of one Senegal (either postgraduate, PhD or teacher) and two NASA or French astronomers (French planetary scientists also participated in the experiments).
During the occult observed in Senegal we have collected data using telescopes set out in 21 different sites. This data is photometric measurements, which allows a correct record of the time when MU69 passes in front of the star and blocks its light.
As it is a rainy season in Senegal, we can not collect data in each of the 21 sites. Overall, three sites had useful information.
However, given the weather during the night of the night, we were very pleased that the occultation was observed.
Roots of our solar system
In Senegal, astronomy is not taught at university level. However, the government in Senegal builds a planetarium and a astronomical observatory.
For the new generation, we would like Senegal to focus on research areas where it can contribute, based on equipment available, expertise and financial methods.
This includes monitoring the effects of meteoroid on the Moon or large planets, the survey of various stars, searching for observation of exoplanets, or monitoring of large planets atmosphere.
A MU69 by New Horizons audit will enable us to understand more about the origin of our solar system.
The flyby will reveal an unknown world. As for Pluto, the information about this object will change from small dot & # 39; For images a high resolution of mysterious landscapes.
Ideas were raised, such as organizing a future workshop of planetary atmospheres. We learn a lot by comparing our planet with other planets, and in the context of climate change, such a workshop about planetary atmospheres in Senegal would make sense.
