This Friday, @SpaceX's Dragon will launch to the @Space_Station, carrying important supplies—including a spare "hand" for Canadarm2 and food for @Astro_DavidS's upcoming mission: http://ow.ly/tn3w30kBDK7 .

On the final leg of a three-day trip after liftoff fr om Cape Canaveral on Friday, a SpaceX Dragon supply ship packed with nearly three tons of cargo is set to arrive at the International Space Station around 7 a.m. EDT (1100 GMT) Monday.

Astronauts Ricky Arnold and Drew Feustel will use the space station's Canadian-built robotic arm -- Canadarm 2 -- to capture the Dragon capsule.

The unpiloted Dragon supply ship carries more than 5,900 pounds (nearly 2,700 kilograms) of hardware, crew provisions and experiments. The supplies include an AI-enabled robot helper for the station crew, and an instrument from NASA's Jet Propulsion Laboratory designed to study plant health and stress.

Members of the station crew will be on standby to manually issue hold or retreat commands to the Dragon spacecraft, which will be flying on autopilot.

Laser navigation sensors and thermal cameras aboard the Dragon capsule will collect data on the range, closure rate and orientation between the supply ship and the space station.

The Dragon capsule lifted off at 5:42 a.m. EDT (0942 GMT) Friday from Cape Canaveral.

Since liftoff, the cargo craft has completed several orbit adjustments using its rocket thrusters to boost itself to the space station's altitude more than 250 miles (400 kilometers) above Earth.

The Dragon will arrive at a hold point 350 meters -- or 1,150 feet -- below the space station at 5:04 a.m. EDT (0904 GMT), around two hours before its scheduled capture by the robotic arm. The spacecraft will conduct a 180-degree yaw maneuver to align its grapple fixture with the position of the station's robotic arm before continuing the approach.

Soon after beginning its final approach sequence, the Dragon spacecraft will halt again at a hold position 250 meters, or 820 feet, below the space station at 5:19 a.m. EDT (0919 GMT). This brief hold allows ground controllers to assess the status of the rendezvous and issue a "go" for the Dragon to enter the so-called keep-out sphere, an imaginary circle around the space station in which traffic is tightly controlled for safety reasons.

The Dragon spacecraft should depart the 250-meter hold point around 5:34 a.m. EDT (0934 GMT), heading for a 30-meter hold position before pressing on to a final point about 10 meters, or 33 feet, beneath the space station for capture by the robot arm.

Once in the grasp of the robot arm, Dragon will be maneuvered to a berthing port on the space station's Harmony module, wh ere it will stay until Aug. 2. The supply ship will head back to Earth for a parachute-assisted splashdown in the Pacific Ocean with around two tons of research specimens and other equipment requiring analysis and refurbishment.

#Dragon is now approx 39nm behind @Space_Station and 5 miles below. 2.5 days to get here. Docking with Station in about 6 hrs, as it whizzes over mi casa.

The @SpaceX #Dragon is 24 minutes ahead of its timeline with a possibility of an early capture at the station this morning... #AskNASA https:/www.nasa.gov/live

The @SpaceX #Dragon is less than 60 Meters from the station as both spacecraft orbit over Africa. #AskNASA https://www.nasa.gov/live

The Dragon spacecraft is at a hold point 30 meters, or 98 feet, from the space station. There will be polls of teams in Houston and Hawthorne in the next few minutes before departing this hold point.

Astronauts Ricky Arnold and Drew Feustel will ensure that the Dragon appears to be in the correct position for this point in the rendezvous. The crew has a control panel linked with Dragon via UHF radio to issue simple commands in case of any problem. For example, the astronauts could tell the spacecraft to hold, abort or retreat.

Arnold and Feustel are inside the space station's cupola module for this morning's arrival.

Dragon has been given a "go" to move towards capture position.

Crew given a "way ahead of schedule" night capture option, but can decide to wait for a daylight option.
