Since SpaceX launched its first crewed mission into space — the first U.S.-based launch of astronauts since the space shuttle program was retired — the company has upgraded its Crew Dragon capsule to make room for cargo missions, according to a recent tweet.

It may seem trivial to the average observer, but with ongoing and cargo-intensive crewed missions compounded by the International Space Station (ISS) remaining docked with a Crew Dragon spacecraft for all of 2021 — SpaceX is fast becoming a legacy space service that will likely become a major historical basis for space exploration.
