Surgery in microgravity is possible and has already been carried out, albeit not on humans yet.
For example, astronauts have managed to repair rat tails and perform laparoscopy – a minimally invasive surgical procedure used to examine and repair the organs inside the abdomen – on animals, while in microgravity.
Surgery by a robot controlled from another lab was successfully used to remove a fake gallbladder and kidney stone from a fake body
These surgeries have led to new innovations and improvements such as magnetising surgical tools so they stick to the table, and restraining the “surgeonaut”.

There is a wealth of research and preparation for the possible event of a surgical emergency during a Mars mission, but there are many unknowns, especially when it comes to diagnostics and anaesthesia. Ultimately, prevention is better than surgery. So selecting healthy crew and developing the eng...
One problem was that, during open surgery, the intestines would float around, obscuring the view of the surgical field. To deal with this, space travellers should opt for minimally invasive surgical techniques, such as keyhole surgery, ideally occurring within patients’ internal cavities through ...
With plans to put humans on Mars in the near future, a medical emergency beyond the stars could spell disaster. Nina Louise Purvis looks at how to fix this problem
But how likely is it that an astronaut will actually need surgery?
As well as distance, the extreme environment faced during transit to and on Mars includes
Robotic surgery is another option that has been used routinely on Earth and tested for planetary excursions.
The surgeries carried out in space so far have revealed that a large amount of support equipment is essential. This is a luxury the crew may not have on a virgin voyage to Mars.
When orbiting or settled on Mars, however, we would ideally need a hypothetical “traumapod”, with radiation shielding, surgical robots, advanced life support and restraints.
Bodily fluids will also behave differently in space and on Mars. The blood in our veins may stick to instruments due to surface tension.
