At 6:01 p.m. EDT on July 25, 2019, SpaceX’s Falcon 9 rocket launched from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida carrying the uncrewed Dragon spacecraft on the company’s 18th Commercial Resupply Services (CRS-18) mission.
Due to arrive at the International Space Station on July 27, the Dragon spacecraft contains multiple supplies, equipment and material critical for supporting science and research investigations at the space station.
The launch of SpaceX’s 18th Commercial Resupply Services mission to the International Space Station – scheduled for this evening – has scrubbed due to unfavorable weather conditions.
Launch is now scheduled for Thursday, July 25, at 6:01 p.m. EDT. Launch coverage will begin at 5:45 p.m. on NASA TV and the agency’s website. A launch on Thursday would result in the Dragon spacecraft arriving to the space station Saturday, July 27.
The launch of SpaceX’s 18th commercial resupply services mission to the International Space Station for NASA is scheduled for 6:24 p.m. EDT with an instantaneous launch window. The SpaceX Falcon 9 rocket and Dragon spacecraft have been moved to the vertical launch position. Launch coverage will begin at 6 p.m. on NASA Television and the agency’s launch blog.
Meteorologists with the U.S. Air Force 45th Space Wing continue to predict a 30% chance of favorable weather for liftoff. The primary weather concerns are the cumulus cloud rule, lightning rule and attached anvil rule.
Packed with more than 5,000 pounds of research, crew supplies and hardware, the Dragon spacecraft will launch on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

NASA and SpaceX now are targeting 6:24 p.m. EDT on Wednesday, July 24, for the company’s 18th cargo resupply mission to the International Space Station. The Dragon spacecraft will launch from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, and arrive at the space station on Friday, July 26, filled with about 5,500 pounds of science, cargo and crew supplies for the microgravity laboratory.
A new International Docking Adapter, called IDA-3, is scheduled to arrive at the International Space Station this July aboard SpaceX’s 18th cargo resupply mission to the microgravity laboratory. When installed on the space station, the one-of-a-kind outpost will have two common ports enabling expanded opportunities for visiting vehicles, including new spacecraft designed to carry humans for NASA’s Commercial Crew Program.
The docking adapters are the physical connections spacecraft like Boeing’s CST-100 Starliner, SpaceX’s Crew Dragon and future, yet-to-be designed international spacecraft will use to autonomously attach to station. The adapters are important because the plans are readily available for spacecraft builders and standardize a host of docking requirements.
Currently stowed in the trunk of SpaceX’s Dragon cargo spacecraft, the IDA-3 was assembled at NASA’s Kennedy Space Center in Florida, and comprises of a number of sensors that spacecraft will communicate with and connect to through use of onboard computers and navigation systems. Docking requires no crew assistance and can be completed much more quickly than the berthing process often used for cargo spacecraft today, which may involve astronauts aboard the station manually capturing spacecraft using a robotic arm then maneuvering the craft to attach to a common hatch mechanism.
IDA-3 is one of the primary payloads on the SpaceX resupply mission and is identical to the International Docking Adapter-2, IDA-2, installed in the summer of 2016. IDA-2 was used by SpaceX during the company’s first uncrewed flight test, called Demo-1, for commercial crew. Both docking adapters were built by Boeing.
Once at the space station, flight controllers will use the station’s Canadarm2 robotic arm to remove the IDA-3 from Dragon’s trunk and place it over a Pressurized Mating Adapter (PMA-3) on the station’s Harmony module, or Node 2. Later this summer, two Expedition 60 crew members will perform a spacewalk to permanently install the IDA-3 to PMA-3.
The SpaceX CRS-18 mission is scheduled to launch at 7:35 p.m. EDT on Sunday, July 21, from Space Launch Complex 40 at Cape Canaveral Air Force Station. After its arrival, the Dragon cargo spacecraft will remain at the space station for about a month.
A SpaceX Dragon cargo spacecraft is scheduled to launch at 7:35 p.m. EDT on Sunday, July 21, on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. This will be SpaceX’s 18th Commercial Resupply Services contract mission to the International Space Station for NASA.
Launch on July 21 results in an arrival at the space station for a robotic capture by Expedition 60 crew members Nick Hague and Christina Koch of NASA on Tuesday, July 23, at 7 a.m. EDT for about a month-long stay.

Two days after its launch from Cape Canaveral Air Force Station in Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the International Space Station’s Harmony module on Monday, May 6, at 9:32 a.m. EDT.
The 17th contracted commercial resupply mission from SpaceX (CRS-17) delivered more than 5,500 pounds of research, crew supplies and hardware to the orbiting laboratory. After Dragon spends approximately one month attached to the space station, the spacecraft will return to Earth with about 4,200 pounds of cargo and research.
While the International Space Station was traveling over the north Atlantic Ocean, astronauts David Saint-Jacques of the Canadian Space Agency and Nick Hague of NASA grappled Dragon at 7:01 a.m. EDT using the space station’s robotic arm Canadarm2.
Ground controllers will now send commands to begin the robotic installation of the spacecraft on bottom of the station’s Harmony module. NASA Television coverage of installation is scheduled to begin at 9 a.m. Watch online at www.nasa.gov/live.
The Dragon lifted off on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida Saturday, May 4 with more than 5,500 pounds of research, equipment, cargo and supplies that will support dozens of investigations aboard the orbiting laboratory.
Here’s some of the research arriving at station:
NASA’s Orbiting Carbon Observatory-3 (OCO-3) examines the complex dynamics of Earth’s atmospheric carbon cycle by collecting measurements to track variations in a specific type of atmospheric carbon dioxide. Understanding carbon sources can aid in forecasting increased atmospheric heat retention and reduce its long-term risks.
The Photobioreactor investigation aims to demonstrate how microalgae can be used together with existing life support systems on the space station to improve recycling of resources. The cultivation of microalgae for food, and as part of a life support system to generate oxygen and consume carbon dioxide, could be helpful in future long-duration exploration missions, as it could reduce the amount of consumables required from Earth.
Dragon successfully launched on the SpaceX Falcon 9 rocket at 2:48 a.m. EDT from Cape Canaveral Air Force Station in Florida, carrying more than 5,500 pounds of research, hardware, and supplies to the International Space Station.
A SpaceX Falcon 9 rocket and Dragon spacecraft stand ready for a second launch attempt today on the company’s 17th commercial resupply mission to the International Space Station.
Liftoff is targeted for 2:48 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station, with an instantaneous launch window. Join us on NASA’s launch blog and on NASA Television beginning at 2:30 a.m. for updates from the countdown.
