Timeline for Rocket Lab’s launch of DARPA’s R3D2 tech demo satellite – Spaceflight Now

Rocket Lab’s light-class Electron launcher is about to take off on its fifthflight from New Zealand, aiming for a 264-mile-high (425-kilometer) orbit with DARPA’s R3D2 expertise demonstration satellite tv for pc.

The 2-stage, 55-foot-tall (17-meter) rocket is scheduled for liftoff throughout a four-hour window opening at 6:30 p.m. EDT (2230 GMT) Sunday from Rocket Lab’s industrial launch complicated on Mahia Peninsula on New Zealand’s North Island.

The privately-developed Electron launcher is making its fifth flight after its maiden flight in Could 2017 reached house, however faltered earlier than reaching orbit, adopted by 4 profitable missions in a row that deployed nanosatellites into low Earth orbit.

Learn our mission preview story for particulars on the launch and the R3D2 satellite tv for pc.

The timeline posted under is accompanied by animation supplied by Rocket Lab that illustrates the approximate look of the main flight occasions.

T-Zero:00:00: Liftoff

The Electron rocket lifts off on the ability of 9 kerosene-fueled Rutherford major engines, producing 34,500 kilos of thrust at liftoff and powering as much as 41,500 kilos of thrust because the rocket climbs into the higher environment.

T+Zero:01:20: Max-Q

The Electron rocket experiences probably the most intense aerodynamic pressures at this section of flight.

T+Zero:02:34: MECO

The 9 first stage Rutherford major engines shut down after a two-and-a-half minute burn.

T+Zero:02:37: First Stage Separation

The Electron’s first stage separates from its second stage.

T+Zero:02:41: Second Stage Ignition

The Electron’s second stage Rutherford engine ignites to proceed the journey into orbit, producing roughly 5,00Zero kilos of thrust in vacuum.

T+Zero:03:06: Fairing Jettison

The Electron rocket’s payload fairing, which protected the satellites through the preliminary section of ascent, jettisons as soon as the rocket is above the dense, decrease layers of the environment. The composite three.9-foot-diameter (1.2-meter) shroud will fall into the Pacific Ocean.

T+Zero:08:53: SECO

The second stage’s Rutherford vacuum engine shuts down after reaching an elliptical parking orbit.

T+Zero:08:57: Kick Stage Separation

The Electron rocket’s kick stage separates from the second stage.

T+Zero:49:52: Kick Stage Ignition

The kick stage’s Curie engine ignites for a 90-second burn to put the mission’s CubeSat payloads right into a round 264-mile-high (425-kilometer) orbit with an inclination of 39.5 levels. The Curie engine burns a proprietary non-toxic “inexperienced” propellant and produces about 27 kilos of thrust.

T+Zero:51:45: Kick Stage Shutdown

The kick stage’s Curie engine shuts down after attaining the right orbit.

T+Zero:53:15: R3D2 Separation

DARPA’s 330-pound (150-kilogram) Radio Frequency Danger Discount Deployment Demonstration satellite tv for pc separates from Rocket Lab’s Curie kick stage.
