SpaceX won’t be the only company reusing its rockets for payload deliveries. Rocket Lab has unveiled plans to recover the first stage of its Electron vehicle. The strategy’s first phase will have Rocket Lab recovering the stage from the ocean and refurbishing it for later. A second phase will be more… audacious. The company intends to have the stage “captured mid-air” by a helicopter, with the aircraft hooking on to the rocket’s parachute array during the descent. It won’t be as elegant as SpaceX’s rocket landings, but it will be efficient if it works as planned.
The launch window was scheduled to open at 11:30 PM ET, but NASA and SpaceX are now targeting takeoff for 2:30 AM ET. The launch window extends until 3:30 AM, and a backup window will open tomorrow night between 11:30 PM ET and 2:30 AM ET.
This flight is also important because of its payload, which includes things like NASA’s Deep Space Atomic Clock and the Green Propellant Infusion Mission. After launch, we’re in for another triple landing attempt, with the two side boosters coming down at Cape Canaveral and SpaceX attempting another sea landing for the center core and, hopefully, bring it all the way home this time.
Less than nine minutes later, the rocket’s first stage booster fell from the sky and executed a pinpoint propulsive landing just offshore, setting the stage for another resupply mission for NASA using the same rocket this summer using the same vehicle.
The 213-foot-tall (65-meter) rocket lifted off with a flash from its nine Merlin 1D main engines at 2:48:58 a.m. EDT (0648:58 GMT), roughly the moment Cape Canaveral rotated under space station’s orbital plane.
The Falcon 9 tilted toward the northeast to align with the space station’s flight path, riding 1.7 million pounds of thrust as roared into a starry sky. Less than two-and-a-half minutes later, the rocket’s first stage booster shut down and separated to begin a descent back to Earth, targeting SpaceX’s drone ship “Of Course I Still Love You” parked around 14 miles (22 kilometers) east of Cape Canaveral in the Atlantic Ocean.
The first stage lit three of its engines to begin a boost-back burn to reverse course and head back toward Florida’s Space Coast, while the Falcon 9’s upper stage continued with the primary objective of Saturday’s mission — the delivery into orbit of a Dragon cargo craft packed with 5,472 pounds (2,482 kilograms) of supplies, provisions and experiments for the station and its six-person crew.
The interaction exhaust plumes from the Falcon 9’s first and second stage Merlin engines produced a spectacular lighting effect, giving the appearance of a cosmic nebula high above the Florida spaceport.
