The cargo aircraft is expected to reach the ISS in two days.
The Progress MS-28 is carrying 2,621 kilograms of cargo, including 950 kilograms of fuel, 420 liters of drinking water, 50 kilograms of compressed nitrogen in cylinders, and about 1,201 kilograms of equipment, materials, food, clothing, and supplies for scientific experiments.
The vessel is transporting the SPIN-X1-MVN X-ray spectrometer, which the cosmonauts will install outside the Zvezda module during extravehicular activities.
The spectrometer will allow scientists to perform an almost complete periodic survey of the celestial sphere in the X-ray region.
