On December 25, according to foreign media reports, NASA's upcoming Artemis program will enable astronauts to return to the moon for the first time in decades, but it will also become a stepping stone for landing on Mars. To this end, the agency is trying to figure out how to provide food, clothing and protection for astronauts during extremely long missions < p > < / P > < p > SpaceX, an American space exploration technology company, recently delivered many holiday supplies for the astronauts of the international space station, including Christmas gifts, roast turkey and detergent. Astronauts on the international space station will experiment with this specially developed detergent to see how it washes clothes in space < p > this detergent is produced by P & G for scientific experiments. According to Procter & Gamble, astronauts on the international space station will wear a suit for a few days before they change new clothes. The new clothes were delivered to them with the goods from the earth < p > mark Sivik, senior director and researcher of P & G, said: "if there is no laundry solution, 160 pounds will be transported for each astronaut stationed on the international space station every year (about 72.5kg). Once you start a long space trip, detergent becomes a necessity. We consider four people washing clothes and minimize the amount. "< / P > < p > NASA estimates that if the laundry function is not provided, astronauts need 500 pounds (about 227kg) of clothes per person to travel to Mars. Sivik said: "What we are developing here is completely degradable and designed to work in the closed-loop system of the space station." < p > in the first experiment, researchers will observe the performance of this specially designed detergent in space. Procter & Gamble will also conduct a follow-up experiment next year to ship stain removal products including tide to go wipes and tide to go pens to see how they remove stains in space < p > the experiment on Tide detergent will also help NASA figure out how astronauts on future manned missions to the moon and Mars will wash clothes on a long journey. The study not only provides a way for future space travelers to clean their clothes, but also may be effective for people in water scarce areas, because detergents are designed to use less water < p > NASA plans to return humans to the moon by 2025. Then it plans to build a lunar base and eventually send astronauts to Mars. (small) < / P > < p >
