A recent instance in which a space mission did not proceed as planned was that of a Russian cargo spacecraft en route to the International Space Station (ISS), which experienced a technical glitch in its journey to dock with the ISS. The cargo spacecraft was transporting vital supplies for the astronauts who are part of the ISS crew. The mission experienced a malfunction in one of its most important components shortly after its launch. Although not hazardous, it was a mission that required experienced cosmonauts to take charge and maneuver the spacecraft manually.
What caused the ISS docking problem
The problem started with the launch of the Progress MS-33 cargo ship into orbit aboard a Soyuz 2.1a rocket from the Baikonur Cosmodrome in Kazakhstan. Soon after achieving orbit, mission engineers noticed a malfunction with one of the KURS automated docking system antennas aboard the spacecraft. The KURS system is an automated system that helps dock a spacecraft safely with the ISS. According to NASA live, “the antenna failed to deploy properly, which means that the cargo ship cannot use its usual system to dock with the station.” The KURS system is a standard system used by Russia to dock its spacecraft with the ISS.
Why manual docking was required
However, because the automated system was unable to operate in full capacity, it was decided to implement a manual docking procedure. This was assigned to the ISS commander Sergei Kud-Sverchkov. This would involve the commander manually guiding the spacecraft to dock at the station using a backup system.NASA through an X post reported that in the event that the problem with the antenna was to persist, the spacecraft would operate using the TORU manual system. This system allows the cosmonauts to operate the spacecraft manually from the station.Of particular note is that manual docking is not a novel practice. This is according to Oleg Kononenko, head of Russia’s Cosmonaut Training Center. He said, “manual approach… is regularly practiced by cosmonauts in training.”
What the spacecraft was carrying
However, despite this technical issue, the Progress MS-33 spacecraft continues its journey to the ISS with all other systems functioning normally.The cargo in this shipment is very important for the day-to-day activities of the crew. The cargo includes:
- Food and drinking water
- Fuel for station maneuvers
- Oxygen and life support equipment
- General equipment and maintenance supplies
The total cargo shipped in this mission is around 2.5 tonnes.
Why this incident matters for space missions
Although the situation was managed properly, it is a reminder of one of the most important aspects of space exploration: redundancy and human skills are still of paramount importance.The spacecraft is quite advanced in terms of technology; however, there is always planning for unexpected machine failure. The capability to change from automatic to manual mode for docking is a testament to the robustness of the planning and training of the astronauts.It is also a testament to experience gained over the years. The TORU system, being a backup, is something that Russian space technology has been using for quite some time.
A small glitch, a strong system
In the intricate world of space exploration, even minor technical hitches may have significant repercussions if not properly addressed. In this case, however, the problem with the antenna was quickly identified and addressed properly.This case is a reminder that, despite the sophisticated technology involved in space exploration, it is the knowledge and preparedness of the astronauts that will guarantee the success of the mission, even when things do not go as planned.
