I don't own mass effect or any other franchise I take inspiration from although I wish I did, this is a story that I've been thinking about for a short period of time and I hope you like it because I don't know if I will follow it after this part, well let's start.

Another thing this chapter and the next one (if you have a next one) take place before the asari found the citadel so the humans will have a lot of time to advance their technology.

JULY/13/2030: A meteor shower hits the earth causing hundreds of deaths, scientists are baffled as to why this catastrophe occurred.

JULY/25/2030: Observatories from all over the world, along with several in orbit, turn their lenses to the place where the steroids came from. After several days of observation, it was determined that the cause was a neutron star.

AUGUST/09/2030: after several computer simulations it was determined that the star named EHK-709273 is heading directly towards the earth. According to estimates we only have 153 years before the star passes so close to the solar system that it destabilizes all planetary orbits and destroys several others including the earth.

(From here on I will use a countdown)

151 years before the impact: after a year of discussions of the main countries of the world (United States, Russia, China, Japan, India) as well as several nations of the world choose to finance the ark project, this decision was taken after consulting with several scientists the best solution to save the human race.

147 years before the impact: once the construction of a city is finished, it will house the scientists of the whole world in charge of the Ark project, the city is called Horizon.

145 years before impact: the design and type of propulsion of the ship that will be the future of humanity is determined. It was determined that it would be an O'Neill cylinder 50 kilometers long and 6 kilometers wide, the propulsion will be by means of antimatter and the source of energy will be by means of several nuclear fusion reactors.

135 years before the impact: the plans for the spacecraft are completed and it is sent to all countries with a space program, 35 kilometers will be a habitable donut with apartment buildings 2 kilometers high it is estimated that 6 to 7 million people will be able to fit 10 kilometers more will be used as natural shelter than recreate it several areas of the earth such as deserts, jungle, sheet and hydroponic areas for algae cultivation and insect breeding for the food source for all people, these areas will be divided by huge walls of newly created molecularly improved titanium called titanium A( it is discussed whether it would be better to use this metal in the whole ship, in the end it is decided to use it in the whole ship) the antimatter propulsion system will be a 5 km section that can be dismantled in case the engine fails.

130 years before the impact: the first rockets that carry parts of the ship's super structure were already launched into orbit for assembly in orbit, green light silk for the construction of two smaller cylinders of 10 kilometers long and 3 wide one wax used as within repair and research of new technologies, will be loaded as much as possible of metals such as lithium, gold, cilice, titanium A and various metals.

The other will be used as a mega hospital with the best medical and genetic technology, the first pieces of the ships already under construction on land.

100 years before the impact: the repair cylinder nicknamed hephaistos is already finished not without several accidents that claimed the lives of several workers either on earth or in orbit, its sister ship named Asclepius by the God of medicine and healing is at 90% completion, with the ship Hephaestus already finished it is estimated that the completion of the ship The ARCA which is at 45% will be completed in half the time scheduled 30 years instead of 60.

95 years before impact: more meteorites impact the earth as the neutron star approaches the solar system, these impacts have caused delays in the launch of more parts of the project's main spacecraft and caused hundreds of deaths worldwide, the Asclepius spacecraft is completed.

begins to take genetic samples from the largest number of people on the planet in order to determine who will go on the ship.

80 years before the impact: samples of soil, plants and animals are being collected to be transferred to the finished part of the ship EL ARCA it is estimated that 90% of the terrestrial species can be saved, most of these species are herbivores and non migratory birds most of the carnivores that will be taken to the ark are scavengers to be able to get rid of the corpses of the animals with the least intervention of human beings and 50% of the river species, it is estimated that the ecosystems recreated will self-sufficient in 15 years.

Riots start around the world claiming that the selection mode is manipulated and ARCA project is terminated (mainly these protests are taking place in Africa and Central America).

70 years before the impact: the construction of EL ARCA is completed and the first people board the ship. It is estimated that the ship will be able to leave within 5 years.

65 years before the impact: the ecosystems are already self-sufficient without human intervention, the last people go on board the built ships, 6 million civilians and another million in specialized personnel in different fields are distributed among the three ships, the first children are born in space.

63 years before the impact: the departure of the ships was delayed due to the implementation of new electronic systems, engines, and fusion reactors.

The Hephaestus was equipped with new, more efficient machinery systems and a huge valve at the front of the ship to allow faster introduction of cargo or the placement of asteroids inside the ship to mine them. Several hangars for cargo ships, 200 meters long and 100 meters wide, were also implemented.

Asclepius is provided with the latest medical equipment as well as the implementation of more hangars to be able to carry a total number of 100 ships of 110 meters long and 50 meters wide each.

Several new hangars were implemented at EL ARCA to be able to receive and store more ships, a belt with 100 ships for cargo transport and 300 for people transport.

60 years before the impact: the ships start their engines and head towards a star 10 light years away called EZ3618 that according to estimates has a planet with liquid water and a breathable atmosphere. It is estimated that this star will be reached in 124 years from now if the speed of 7% of the speed of light is maintained.

Zero hour: the outer planets no longer exist, they were adsorbed by the neutron star, Mars was thrown out of the solar system, the earth was torn apart and turned into nothing more than a ring system orbiting the star, venus and mercury were thrown into the sun, the only thing left of the system is the debris of the different planets and a small observation probe deployed from THE ARK to see what would happen to the sun system and thus have evidence of the destruction of the planet earth the transmission will arrive in 5 years to the ship.

I hope you liked this part because I had a hard time writing it and I'll see you in the next part.

I was inspired by a Natgeo documentary called Evacuate Earth,
