05/31/2017 17:52  Rollout complete


Ground crews rolled out the H-2A rocket from its assembly building at the Tanegashima Space Center a few hours ago.

The rocket was fixed on top of a mobile launch tower for the 1,600-foot (500-meter) journey to Launch Pad No. 1, which took about a half-hour to complete.

The rollout began around 1000 GMT (6 a.m. EDT; 7 p.m. Japan Standard Time).

Technicians planned to plug the launch platform into ground electrical and propellant supplies before fueling begins in the final hours of the countdown. Since the rocket's arrival at the pad, the launch team has given the "go" to begin filling the H-2A with liquid propellants.

Once the launch team checks out the rocket's systems and loads it with cryogenic liquid hydrogen and liquid oxygen, an automated countdown sequencer will take over the final steps before liftoff.

Launch is scheduled for 0017:46 GMT Thursday (8:17:46 p.m. EDT Wednesday) with the Michibiki 2 navigation satellite.

Now less than 60 minutes from the planned launch of the H-2A rocket.

Спойлер

Officials just gave the "go" to enter the terminal count, which began at 2317 GMT. The final hour of the countdown will prepare the rocket, the payloads, and ground systems for flight.

The H-2A rocket for today's launch is flying in the "202" configuration with two large 15-meter-long (49-foot) solid rocket boosters and without any of the smaller strap-on boosters sometimes used to augment the launcher's thrust.

It also features a standard four-meter (13.1-foot) diameter nose shroud, which encloses the Michibiki 2 spacecraft for the first few minutes of flight through the lower atmosphere.

The lead contractor for the H-2A rocket is Mitsubishi Heavy Industries.

T-minus 20 minutes. Engineers are uploading the latest upper level wind data into the H-2A's flight computer. The rocket will use the information to compute a specific steering profile based on the real launch day weather conditions. 

At liftoff, the H-2A will be propelled upward from the launch pad on the power of a single hydrogen-burning LE-7A main engine and two solid rocket motors. The total liftoff thrust of the rocket is approximately 1.4 million force pounds. 

The rocket will pitch east from Tanegashima, racing through the speed of sound in less than a minute and reaching an altitude of more than 30 miles in the first two minutes of flight. 

After consuming their pre-packed solid propellant, the two strap-on boosters will jettison at about the two-minute point. The 13.1-foot diameter payload shroud will separate at T+plus 4 minutes, 10 seconds after the H-2A rocket ascends above the discernable traces of Earth's atmosphere. 

First stage main engine cutoff, stage separation and ignition of the second stage's LE-5B engine will occur nearly seven minutes into the mission. The second stage will burn for nearly six minutes before shutting down at T+plus 12 minutes, 34 seconds. 

After a 12-minute coast, the second stage will reignite for a 3-minute burn.

Deployment of the Michibiki 2 satellite is expected at T+plus 28 minutes, 24 seconds.
