during the rendezvous. Two course correction burns were also performed on Flight Day 2. The first 10-second burn, dubbed NC-2, was performed using the right-hand OMS engine, changing the shuttle's speed by . The burn raised both the apogee and perigee of the shuttle's orbit by . Atlantis' reaction control jets were again fired for a second time to execute the 8-second NC-3 burn, which changed the shuttle's velocity by about . Meanwhile, Mission Control managers determined that the ISS would not need an avoidance maneuver to avoid a piece of orbital debris. Updated tracking information showed that the ISS and the debris would not pass close enough the following day to require any action. May 16 (Flight Day 3 – Docking) The STS-132 crew began their day at 07:20 UTC and prepared to dock with the ISS. Commander Ken Ham performed a series of rendezvous burns (NH, NC4 and TI) to boost the orbit of Atlantis to match with that of the ISS. The longest of these, the 1-minute-24-second-long orbit raising maneuver or NH burn, changed Atlantis' velocity by 132 feet per second, and placed the shuttle into a new 212-by- orbit. A 63-second circularization burn, known as NC4, boosted Atlantis into a 214-by- orbit. At 11:40 UTC, with about separating the shuttle and the ISS, commander Ken Ham performed the final 12-second terminal initiation (TI) burn, firing the left OMS engine of Atlantis. By 13:26 UTC, with Ken Ham flying the shuttle from the aft flight deck, Atlantis positioned itself beneath the ISS and began the 360-degree flip rendezvous pitch maneuver (RPM). As the shuttle's underside rotated into view, three ISS crew members – Oleg Kotov using a camera with a 400mm lens, and Timothy Creamer and Soichi Noguchi using two 800mm-lens cameras – took 398 photographs of Atlantis belly, as part of post-launch inspections of the thermal protection system.Atlantis docked with the ISS Pressurized Mating Adapter-2 at 14:28 UTC as the two orbited over the South Pacific Ocean. After docking, the ISS was reoriented by the small vernier thrusters on Atlantis to minimize the risk of Micro-Meteoroid Orbital Debris (MMOD) impacts upon the shuttle. A series of leak checks were done on both sides of the hatch by the shuttle and station crews, before the hatches were opened at 16:18 UTC. After a brief welcoming ceremony by the station crew, Atlantis astronauts received the standard station safety
