Scientists have launched menstrual cups into house for the primary time, testing whether or not these reusable gadgets can stand up to the intense circumstances of house journey. The AstroCup mission represents a key step towards giving feminine astronauts sustainable menstrual well being choices throughout lengthy period missions to the Moon and Mars.
Since Sally Experience’s historic house shuttle flight in 1983, when NASA famously requested if 100 tampons can be sufficient for every week lengthy mission, managing menstruation in house has been an ongoing problem. At the moment, most feminine astronauts use hormonal contraception to suppress menstruation totally throughout missions. Whereas this method has sensible benefits, it isn’t appropriate for everybody and raises well being considerations for very lengthy missions as we step additional out into the Photo voltaic System.

With formidable plans for lunar bases and Mars expeditions that might final years and even a long time, researchers recognised the pressing want for sustainable alternate options. An astronaut collaborating in a number of Artemis missions for instance might face over a decade of menstrual suppression, whereas somebody concerned within the full program from 2025 to 2035 would possibly require practically 20 years of hormonal therapy.

The AstroCup group, led by L ́ıgia F. Coelho from Cornell College, launched 4 commercially out there menstrual cups aboard the Baltasar rocket throughout a European competitors in October 2022 with two cups flying into house whereas two remained on the bottom as controls. The rocket reached over 3 kilometres altitude throughout a 9 minute flight that subjected the cups to forces 16 occasions higher than Earth’s gravity. Earlier than and after the flight, researchers carried out rigorous testing utilizing water and glycerol to judge the cups’ structural integrity and leak proof efficiency.
The house flown menstrual cups carried out flawlessly. Visible inspections revealed no indicators of wear and tear or tear however extra importantly, the cups confirmed no leakage of both take a look at liquid, sustaining their seal integrity regardless of experiencing excessive acceleration forces, temperature modifications, and stress variations throughout flight. The payload’s onboard sensors recorded difficult circumstances all through the journey with temperatures starting from 32-34°C, humidity dropping to 40%, and atmospheric stress falling beneath 70,000 Pascals at peak altitude.
These outcomes recommend that menstrual cups may very well be a viable answer for managing menstruation throughout house missions. In contrast to disposable tampons or pads, reusable cups would dramatically cut back waste, a important consideration in house the place each gram issues and disposal choices are restricted. Past sensible advantages, this analysis addresses astronaut autonomy and selection in healthcare.

Whereas encouraging, the AstroCup experiment was only a first step. The take a look at occurred in Earth’s environment and gravity, whereas the Moon has one-sixth Earth’s gravity and Mars has one-third. These totally different gravitational circumstances might have an effect on how menstrual fluid behaves when cups are eliminated or repositioned. Future research should look at how the gadgets carry out throughout a number of menstrual cycles, together with cleansing and storage procedures within the surroundings of house.
The AstroCup mission proves that testing ladies’s well being applied sciences for house is each possible and mandatory. With extra ladies becoming a member of house packages around the globe and missions rising longer, making certain that feminine astronauts have protected, efficient menstrual administration choices is not only a technical problem, it’s a basic requirement for the way forward for human house exploration.
