However, that issue was soon removed on August 4, via what was described as a \u201csuccessful reintegration\u201d.<\/p>\n
\u201cSince launch on 29 July, ATV has conducted a series of manoeuvres to bring it up to the Station altitude, and these have gone flawlessly,\u201d noted Jean-Michel Bois of the ESA operations team.<\/p>\n
\u201cThe vessel is functioning perfectly and we are looking forward to a smooth \u2013 and final \u2013 ATV docking.\u201d<\/p>\n

Following these altitude-rising burns, rendezvous operations entered the home leg via the aptly named \u201choming\u201d phase, which involved ATV-5 moving from her S1 waypoint at 30km from the ISS, to the S2 waypoint at 3.5km from the ISS.<\/p>\n
The S-1\/2 maneuver took place at 09:22:00 UTC.<\/p>\n
The homing phase consisted of two 2m\/s homing burns, and two 0.5m\/s correction burns.<\/p>\n

After ATV-5 arrived at the S2 waypoint, the \u201cclosing\u201d phase was initiated, which took the vehicle from the S2 waypoint at 3.5km from ISS to the S3 waypoint at 250m from ISS.<\/p>\nThis phase involved two 1.5m\/s closing burns, and two 0.5m\/s correction burns.<\/p>\n
At the conclusion of these maneuvers, the Final Approach 1 (FA1) phase began, which took ATV-5 from the S3 waypoint at 250m from ISS, to the S4 waypoint at 20m from ISS.<\/p>\n
After arriving at the S4 waypoint, ATV-5 aligned herself with the SM Aft port, untilizing relative guidance, whereupon FA2 began. This took ATV-5 from S4 at 20m to S41 at 12m from ISS.<\/p>\n

The approach was constantly monitored \u2013 but not controlled \u2013 by the crew inside the ISS, until the Crew Hands Off Point (CHOP) was reached when ATV-5 was one meter from the ISS. At this point ATV-5\u2019s own momentum made any propulsive abort ineffective.<\/p>\n(ATV-3 Docking Animation created from 70 hi res ATV-3 docking images acquired by L2 \u2013 LINK).<\/p>\n
Shortly following CHOP, contact and capture was confirmed via ATV-5\u2019s adjoining via the Russian docking probe, which was retracted following shortly thereafter.<\/p>\n
This led to the confirmation of a hard dock between ATV-5 and the ISS \u2013 confirmed at 13:30 UTC.<\/p>\n

Ahead of her arrival at the Station, ATV-5 was involved in an advanced sensor test, On 8 August, ATV-5 performed a \u2018flyunder\u2019 of the Station, passing 8 km below to gather video footage with special cameras installed on its front cone.<\/p>\nThis test is designed to improve the capability of spacecraft when dealing with \u201cuncooperative\u201d targets, such as orbiting debris or a Mars sample capsule.<\/p>\n
The LIRIS demonstrator \u2013 short for Laser InfraRed Imaging Sensors \u2013 was used to scan targets on the outside of the ISS, while onboard computers processed the data using new guidance navigation and control software. The results were recorded by hardware inside the pressurized element of the ship.<\/p>\n
LIRIS was turned on for docking, but it was used in record-mode only, collecting additional data for later analysis.<\/p>\n

ATV-5 is delivering a large load of both internal (dry) and propellant (wet) cargo. Specifically, the pressurized Integrated Cargo Carrier (ICC) section is bringing around 2,600kg of cargo, including food, crew provisions, and scientific hardware to the orbital outpost.<\/p>\nThe Service Module (SM) is carrying 570kg of water, 100kg of gas (air and oxygen), 2,230kg of propellants available for ISS reboosts, and 860kg of propellants for transfer to the Russian Segment (RS).<\/p>\n
In addition to her manifest of cargo, ATV-5 will also serve as a \u201cpropulsion module\u201d while attached to the ISS, aiding in attitude maneuvers, reboosts, and Debris Avoidance Maneuvers (DAMs) \u2013 all via the utilization of her Orbit Correction System (OCS) engines.<\/p>\n

Upcoming milestones are listed as involving pre-scrubbing, initial ingress tasks on Thursday, followed by final ingress and the test of OCS ATV reboost capability on Friday. A reboost is currently scheduled for August 27.<\/p>\nFollowing the conclusion of her Attached Phase Operations (APO), ATV-5 will undock from the ISS for a final time, prior to a destructive re-entry over the South Pacific Ocean. This will mark the conclusion of Europe\u2019s heavy hauler cargo spacecraft\u2019s role with the ISS.<\/p>\n
ATV propulsion hardware will live on via its use on NASA\u2019s Orion spacecraft, following a deal between ESA and the US Space Agency.<\/p>\n
