SpaceX has been flight cargo resupply missions to the International Infinite Station (ISS) for years, only it's gearing up to ship astronauts to and from the station presently. That'due south not the only change in SpaceX's space station activities. Elon Musk'south commercial spaceflight visitor just completed what could be the last Dragon berthing process always at the station. It's all docking from here on out.

Since the beginning of its commercial resupply contract, SpaceX has been using the original Dragon capsule. Notwithstanding, it has been working on the improved Dragon 2 for several years. Naturally, the crewed version of the Dragon two gets nearly of the attention, but SpaceX also has a cargo version of this spacecraft. Future cargo missions volition use this design instead of the classic Dragon, and that means some changes aboard the ISS.

The electric current Dragon capsule uses a berthing process when it reaches the station. Astronauts aboard the ISS employ the robotic Canadarm2 to pluck the capsule out of infinite and guide it to one of the Mutual Berthing Mechanism (CBM) ports. NASA initially settled on this method because the CBM ports were 60 percent larger than standard docking ports (they're the aforementioned ports that concur sections of the station together). This gives the coiffure more control over incoming vessels to make sure they don't accidentally impairment the station, simply information technology eats upwards time.

The Dragon 2 sheathing autonomously docking at the ISS in March 2019.

The ongoing CRS-20 resupply mission will probably be the last time SpaceX needs to use the berthing organisation at the ISS. Starting with CRS-21 afterward this year, its Dragon 2 capsule will use autonomous docking to link upwardly with the ISS. We're already seen this in action, too. Last year'due south test flight of the crew Dragon (without a crew) included an autonomous docking, and it went off without a hitch.

The next step for Dragon 2 may well be a crewed launch later this jump. SpaceX says all its tests have been successful, and then it'due south but waiting on NASA blessing. Astronauts on the Dragon 2 will have the option to take over command of the craft and dock manually, just the flight computer should handle things on its own. CRS-21 with the cargo-only Dragon will launch later in 2020. This arts and crafts won't have seats, controls, or life back up systems, simply it will be able to dock itself at the ISS.
