NASA’s decision to include Astrobee in Gateway, the uncrewed space station, effectively takes over astronaut tasks to keep the spacecraft safe and habitable for human arrival.
To complete the tasks that were initially made to be done by humans so that the Gateway can be habitable, Astrobee is armed with practical components. Astrobee has to carry out in-flight maintenance such as frequent inspection, routine maintenance, and contingency response to keep the space station in a usable condition. Marks (2019) states that the Astrobee can plug in several valuable features such as a robotic arm, a sensing system that provides continuous monitoring, or a barcode reader for inventory taking. Depending on the task assigned, Astrobee can detect the blockage of foreign objects, and also, with the robot arm, they can hold and deliver items when necessary.
Another reason why Astrobee is effective in keeping the Gateway safe for visiting astronauts is due to its multiple surveillance features. Kua J, Loke SW, Arora C, Fernando N, Ranaweera C (2021) revealed that while Astrobee goes on with their daily tasks, they can document their actions with their built-in cameras. Providing real-time updates and monitoring of Astrobee, the robots are equipped with mobile camera views to record and store the videos while providing live streaming of their activity.
Astrobees can take over the tasks done by humans to keep Gateway ready for visitors despite their small size because the robots can work independently and together as a group. Working together with other Astrobees allows them to accomplish tasks that are difficult for them to handle alone. Astrobee is made shaped like a cube. They are small, and size 32 cm wide thus may encounter difficulty delivering too big parts. To counter that, Astrobee is made to collaborate and work with one another to get their job done. Gonzalez (2019) asserted that when the Astrobee is required to handle or transport larger objects around the ISS, Astrobee can team up and work together to manoeuvre the component. After, the robots can split up and resume their daily assignment autonomously.
However, despite the great things Astrobee can do, the robot also holds some risks. Although Astrobee is programmed to halt when an obstacle is detected, there may still be a risk of collision with the crew members or visiting astronauts. When colliding with Astrobee, there is a chance that the robot may crash onto surfaces of the spacecraft, such as the windows, causing damage to the ship. Therefore, Bualat, M. G., Smith, T., Smith, E. E., Fong, T., & Wheeler, D. W. (2018) explained that they had added “corner bumpers and foam padding” to minimise the damage of this risk as much as possible.
Astrobee serves as an effective tool that is capable enough to maintain Gateway in replacement of the actual crew. The robots can set up the spacecraft before and after visiting astronauts. At present, Astrobees are still actively working out in space. To further revolutionise and depend on robots, Astrobee will be one of the key players.
