Watch the perfect landing of SpaceX's Falcon 9 0:40
(CNN) --
SpaceX's Dragon unmanned cargo ship successfully undocked from the International Space Station (ISS) this Sunday morning and is returning to Earth.
The CRS-24 cargo ship successfully exited the ISS "safety sphere" at 10:40 a.m., after a previously scheduled attempt was postponed due to bad weather at its landing site off the coast of Florida, according to SpaceX statements.
The security sphere is a radius of 200 meters around the ISS.
NASA broadcast the undocking live on NASA TV and on its social media platforms.
Dragon is expected to make a "parachute-assisted splashdown" off the coast of Panama City, Florida at approximately 3:05 p.m. Monday, according to NASA.
The splashdown will not be broadcast live, but updates will be provided by NASA's space station blog.
SpaceX's Dragon cargo ship has left the ISS, bringing scientific and medical research to Earth.
Experiments aboard the Dragon spacecraft will be transported to NASA's Space Station Processing Facility at the Kennedy Space Center upon arrival.

"The splashdown off the coast of Florida allows rapid transport of experiments to the NASA Space Station Processing Facility at the agency's Kennedy Space Center in Florida, allowing researchers to collect data with minimal exposure. of the samples to Earth's gravity," NASA said.
This will be the year for the space sector: a SpaceX rocket on Mars, tourism and more billionaire competitions
What does the SpaceX ship bring back?
The cargo ship is bringing back medical supplies along with more than 5,000 pounds of valuable "cargo and research," NASA mission control said during its broadcast.
This includes a retired light imaging microscope, which has been supporting numerous scientific investigations for 12 years, as well as samples of colloid studies.
Cytoskeleton, an investigation to analyze the impact of microgravity on cell signaling molecules, is also on board Dragon.
"This research contributes to our understanding of how the human body responds to microgravity and could support the development of countermeasures to help crew members maintain optimal health on future missions," NASA said.
The Dragon spacecraft was launched on December 21 to carry equipment, research material and supplies for the crew to the ISS.
The return of the cargo ship will mark the 24th "commercial resupply services mission for NASA," according to the space research agency.
