For the very first time, a group of all civilians, four across the board, will take flight aboard a SpaceX mission set to launch on Wednesday, without a professional astronaut on deck.
The four passengers are supposed to incorporate the opening-up of space to everyone, giving the mission a name- Inspiration4.
The flight with no professional is expected to last about 3 days from liftoff to splashdown in the Atlantic.
The billionaire Jared Issacman, founder and CEO of Shift4 Payments, is the commander of the flight. He has handed over an undisclosed but presumably a hefty sum to fellow billionaire and SpaceX owner Elon to send himself and his three crewmates aloft.
Each seat has been assigned to represent a specific value.
Issacman conceived this mission mainly to raise awareness and support for one of his most favourite causes, St. Jude Children's Research Hospital which is a leading pediatric cancer centre in Memphis, Tennessee.
His seat represents "leadership".
Along with him will be physician assistant Hayley Arceneaux. She will be the mission's "medical manager". She was a former patient of the hospital and got treated for bone cancer as a child. She will be the first person to be sent into the earth's orbit in space at the age of 29. Not only this, but she will also be the first person with a prosthesis to go into space.
Her seat represents "hope".
A U.S air force veteran who served Iraq, Christopher Sembroski now works in the aeronautics sector, got selected as the third member of the crew for his donation at the St. Jude fundraiser.
His seat represents "generosity".
Sian Proctor, a geoscientist who was once a NASA astronaut candidate, will be the fourth African American woman to go to space. She achieved her seat by creating an online sales site linked to space as part of a contest by Issacman's company.
Her seat represents "prosperity".
The mission dubbed Inspiration4 will be helping to support Issacman's goal to raise $200 million to help cure children's cancer.
While in the orbit the crew will also be conducting research "designed to advance human health on Earth and during future long-duration space flights", according to SpaceX.
The launch is set to take place from Florida. The five-hour launch window begins Wednesday evening. The Inspiration4 will be in no part to operate the spacecraft. The four will ride in a fully automated Dragon capsule. It is also worth mentioning that SpaceX's Dragon spacecraft functions largely on its own and does not require much human input to operate.
It is the same kind of capsule that SpaceX uses to send astronauts for NASA to and from the International Space Station.
