An electrical problem on SpaceX's drone ship parked just off the coast of Cape Canaveral prompted SpaceX to scrub a Falcon 9 launch attempt early Friday, delaying the start of a resupply mission to the International Space Station by 24 hours.

The Falcon 9 countdown halted around 14 minutes prior to the rocket's appointed launch time at 3:11 a.m. EDT (0711 GMT) Friday. SpaceX's launch director announced over the countdown net that the company's drone ship — the landing vessel where the Falcon 9's first stage will attempt to land offshore — was unable to maintain power.

SpaceX was also evaluating a helium leak in a quick-disconnect interface at the launch pad, but officials cited the drone ship issue as the reason for Friday's scrubbed launch attempt.

Teams lowered the Falcon 9 rocket horizontal to address the helium leak, while the football field-sized drone ship returned to Port Canaveral later Friday morning, presumably for servicing of the vessel's electrical power system.

The drone ship, named "Of Course I Still Love You," departed Port Canaveral a few hours later Friday afternoon to head back to the Falcon 9 booster's targeted landing site 17 miles (28 kilometers) southeast of the rocket's launch pad, or roughly due east of the easternmost point of Cape Canaveral.

A new launch attempt is scheduled for 2:48:58 a.m. EDT (0648:58 GMT) Saturday to begin a cargo resupply mission set to deliver 5,472 pounds (2,482 kilograms) of logistics, equipment and experiments to the International Space Station and its six-person crew.

This morning's SpaceX Dragon launch was scrubbed due to a drone ship power issue. Launch coverage for the next attempt begins at 2:30 a.m. EDT Saturday, May 4, for a 2:48 a.m. launch. Viewers can watch it unfold on NASA Television and the agency's website. This cargo delivery will replenish the International Space Station with nearly 5,500 pounds of science, supplies and hardware.

Saint-Jacques and Hague spent some time to reviewing training and procedures for when they command the Canadarm2 robotic arm to capture the Dragon cargo craft at the International Space Station, which is now scheduled for Monday, May 6, at 7 a.m. following a May 4 launch.

The @PortCanaveral Jetty Park will be opening at 2:00 am on Saturday for the @SpaceX #CRS17 launch attempt. (Yes, I know, FB, but it works)

ЦитироватьLaunch timeline for SpaceX's 17th space station resupply mission
May 2, 2019Stephen Clark

SpaceX's Falcon 9 rocket will go from Cape Canaveral to low Earth orbit in less than 10 minutes Saturday with a Dragon capsule heading for the International Space Station carrying nearly 5,500 pounds of supplies and experiments.

Liftoff is set for 0648 GMT (2:48 a.m. EDT) Saturday from Cape Canaveral's Complex 40 launch pad.

It will be the 70th flight of a Falcon 9 rocket, and SpaceX's fifth launch of the year. Working under contract to NASA, Saturday's launch will be the 17th of least 26 SpaceX resupply missions to depart for the space station under two separate cargo transportation contracts.

The illustrated timeline below outlines the launch sequence for the Falcon 9 flight with the Dragon spacecraft. It does not include times for the descent and landing of the first stage booster on SpaceX's drone ship around 17 miles (28 kilometers) southeast of pad 40.

Three ignitions of the first stage engines after separation will steer the booster back toward Florida's Space Coast from the northeast. Here are key times for the landing maneuvers:
    [/li]
  • T+plus 2 minutes, 34 seconds: First stage boost-back burn begins
  • T+plus 6 minutes, 39 seconds: First stage entry burn begins
  • T+plus 8 minutes, 27 seconds: First stage landing
Touchdown on SpaceX's drone ship "Of Course I Still Love You" should occur during a landing burn with only the first stage's center Merlin 1D engine firing.
Спойлер
T-0:00:00: Liftoff


After the rocket's nine Merlin engines pass an automated health check, hold-down clamps will release the Falcon 9 booster for liftoff from pad 40.

T+0:01:12: Max Q


The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure.


T+0:02:17: MECO


The Falcon 9's nine Merlin 1D engines shut down.

T+0:02:21: Stage 1 Separation


The Falcon 9's first stage separates from the second stage moments after MECO.

T+0:02:28: Second Stage Ignition


The second stage Merlin 1D vacuum engine ignites for an approximately six-minute burn to put the Dragon spacecraft into orbit.

T+0:08:39: SECO


The second stage of the Falcon 9 rocket shuts down after reaching a elliptical target orbit at an inclination of 51.6 degrees. The second stage will later reignite for a de-orbit burn, falling back into the atmosphere for a destructive re-entry.

T+0:09:38: Dragon Separation


The Dragon spacecraft separates from the Falcon 9 rocket's second stage.

T+0:12:08: Solar Arrays Deployed


The Dragon spacecraft's two solar array wings extend one-at-a-time to a span of 54 feet (16.5 meters).

SpaceX's launch conductor has polled his team, and all stations are "go" to begin filling the Falcon 9 rocket with propellants.

T-minus 35 minutes and counting. "Launch auto sequence has started."

The beginning of the launch autosequence kicks off the first steps to begin pumping propellants into the 213-foot-tall Falcon 9 at pad 40 at Cape Canaveral Air Force Station.

RP-1 kerosene and liquid oxygen are now being pumped into the Falcon 9 rocket. The liquid oxygen is chilled to near minus 340 degrees Fahrenheit (minus 206 degrees Celsius).

Loading of RP-1 kerosene fuel into the Falcon 9's second stage is complete. Liquid oxygen loading into the second stage will begin in around three minutes.
