SpaceX launched its 25th cargo mission to the International Space Station. Here's what's on board.

The 25th cargo mission to the International Space Station was launched by the company on July 14.

The mission was launched from the Kennedy Space Center in Florida. After just 2.5 minutes of flight, the first stage of the rocket detached and fell to the ocean floor. The second stage of the rocket continued to propel itself and the uncrewed Dragon craft mounted on its nose.

The Dragon craft is expected to reach the International Space Station at 11:20 a.m. on Saturday. The time is at 10:30 pm Fresh food and supplies, as well as scientific equipment, will be unloaded from the capsule after it docks with the lab.

Equipment for the Earth Surface Mineral Dust Source Investigation is one of the most important deliveries. This experiment will be attached to the outside of the International Space Station to study how dust from arid regions affects the climate. The scientists don't know if mineral dust has an effect on the climate.

Here's every spaceship that's ever carried a person into space.

Roger Clark is a senior scientist at the Planetary Science Institute in Tucson, Arizona and a co-investigator on the EMIT mission. The composition of the dust can affect the temperature of the planet. Light and dark dust may cause different effects. Dust plays a part in the environment.

Dust is an important part of climate models.

The impact of climate change is based on 5,000 samples of soil. More than 1 billion usable measurements will be collected by MIT.

In order to measure the contents of Earth's dust from space, EMIT uses a technique that separates inbound light into different wavelengths. EMIT is able to identify the composition of dust clouds by breaking them down into different colors. The software used to map the detected materials will be unique.

It has been a long time since the launch ofCRS 25. The mission was held back three times because of unsafe levels of corrosive hydrazine vapor in the craft's propulsion system. The rocket was thoroughly inspected before it was given the go-ahead.

The effects of aging on cellular repair and whether those effects can be reversed in astronauts after they return to Earth are two of the experiments that will be carried out on their way to the International Space Station.
