FLORIDA – SpaceX launch cargo mission named CRS-25 to the International Space Station (ISS) on a SpaceX Falcon 9 rocket. The 25th cargo mission carrying 2,630 kilograms of logistics is launched from NASA’s Kennedy Space Center in Florida, Thursday July 14, 2022.
After just 2.5 minutes of flight, the rocket’s first stage detached, landing safely and upright five minutes later aboard SpaceX’s “A Shortfall of Gravity” drone in the Atlantic Ocean. The second stage rocket continued to climb into orbit, propelling itself and the nose-mounted Dragon cargo plane.
The Dragon capsule is expected to slowly make its way to the ISS and reach it on Saturday (16 July 2022) at around 11.20 am. Once Dragon docks with the orbiting laboratory, astronauts will unload the capsule, which carries fresh food and supplies, as well as scientific equipment for dozens of active scientific investigations on the ISS.

One of the largest and most important mission deliveries is equipment for the Investigation of Earth Surface Mineral Dust Sources (EMIT). Once pinned outside the ISS, the experiment will scan Earth to study how dust from arid regions moves with the wind and affects climate.
“Understanding the composition of dust is key to understanding warming versus cooling and by how much, both on a regional and global scale,” said Roger Clark, senior scientist at the Planetary Science Institute in Tucson, Arizona, and a co-investigator at the EMIT mission. , Saturday (16/7/2022).
EMIT can precisely measure Earth’s dust content from space using a technique called imaging spectrometry. Where the incoming light is separated into different wavelengths ranging from ultraviolet to infrared.

Because certain minerals in a dust cloud only reflect certain wavelengths, EMIT can identify the composition of a dust cloud by breaking it down into 288 possible colors. After this identification, the spectrometer will use unique software to map the detected materials to their locations around the world.
It is known, the launch of the CRS-25 mission has long been prepared. It was originally scheduled to take off a month ago. However, the mission was postponed three times after engineers discovered potentially unsafe levels of corrosive hydrazine vapor. NASA and SpaceX engineers inspected the rocket extensively before finally giving it the green light once the plane’s propulsion system was functioning properly.
Other experiments on their way to the ISS will examine the effects of aging on cell repair and investigate whether the effects are reversible on astronauts once they return to Earth, as well as study the feasibility of making concrete from materials found in low gravity. environment of the moon and Mars.
