Rocket Lab is set to launch a small U.S. military technology demonstration satellite from New Zealand Thursday on the company\u2019s first flight since a second stage failure doomed a commercial mission in May.<\/p>\n

The Air Force Research Laboratory\u2019s Monolith microsatellite is set to ride an Electron rocket into orbit Thursday from Rocket Lab\u2019s privately-owned spaceport on the North Island of New Zealand.<\/p>\n

There is a two-hour launch window for the mission Thursday. The window opens at 2 a.m. EDT (0600 GMT; 6 p.m. New Zealand time).<\/p>\n

The mission will mark the 21st flight of a Rocket Lab Electron launch vehicle since 2017, and the eighth to carry a payload for a U.S. military or intelligence agency customer.<\/p>\n

It will be the first Rocket Lab mission since May 15, when an Electron rocket failed before reaching orbit with two commercial BlackSky Earth-imaging satellites.<\/p>\n

Rocket Lab\u2019s internal investigation, with oversight from the Federal Aviation Administration, concluded the failure was caused by a problem with the igniter system on the Electron launcher\u2019s second stage engine.<\/p>\n

\u201cThis induced a corruption of signals within the engine computer that caused the Rutherford engine\u2019s thrust vector control (TVC) to deviate outside nominal parameters and resulted in the engine computer commanding zero pump speed, shutting down the engine,\u201d Rocket Lab said in a statement earlier this month.<\/p>\n

Live video from beamed down from the rocket May 15 showed the second stage\u2019s kerosene-fueled Rutherford engine igniting and immediately begin to tumble about three minutes into the flight. The engine shut down prematurely after firing for a few seconds, well short of a planned six-minute burn.<\/p>\n

The rocket and its two BlackSky payloads fell into the Pacific Ocean downrange from the launch site in New Zealand.<\/p>\n

Rocket Lab said the igniter problem \u201cresulted from a previously undetectable failure mode within the ignition system that occurs under a unique set of environmental pressures and conditions.\u201d<\/p>\n

The company said engineers did not find evidence of the problem during pre-flight testing, which included more than 400 seconds of burn time for the same engine. But Rocket Lab said it was able to replicate the issue after the flight, and teams \u201cimplemented redundancies in the ignition system to prevent any future reoccurrence, including modifications to the igniter\u2019s design and manufacture.\u201d<\/p>\n

The May 15 mission was the third time an Electron rocket failed to reach orbit on 20 attempts since 2017.<\/p>\n

Engineers traced the cause of an Electron second stage failure in July 2020 to a faulty electrical connector, which detached in flight and led to an early engine shutdown.<\/p>\n

Seven small commercial satellites were lost on the failed mission last year. Rocket Lab said it implemented improved testing to better screen for bad connectors, and the company successfully launched its next Electron mission less than two months later.<\/p>\n

Rocket Lab racked up six straight successful Electron missions before the launch failure May 17. The company\u2019s first orbital launch attempt in 2017 failed to reach orbit due to a ground system failure that caused safety teams to send a flight termination command to the rocket.<\/p>\n

The Space Test Program, which helps manage development of the military\u2019s experimental satellites, procured the launch of the Monolith satellite with the Rocket Systems Launch Program, part of the Space Force\u2019s Space and Missile Systems Center.<\/p>\n

Other partners on the mission include the Defense Innovation Unit and the Rapid Agile Launch Initiative, a program that books rides to orbit for small military satellites on emerging commercial small satellite launchers.<\/p>\n

The mission, designated STP-27RM, was originally supposed to launch from Rocket Lab\u2019s new pad at the Mid-Atlantic Regional Spaceport, located at NASA\u2019s Wallops Flight Facility in Virginia. But delays in NASA\u2019s certification of the Electron rocket\u2019s new autonomous flight safety system have kept Rocket Lab from beginning service from the Virginia launch base.<\/p>\n

In June, officials at Wallops said they hope to complete certification of the new autonomous flight safety system by the end of the year, enabling the first Rocket Lab launch from U.S. soil. With the launch of the military\u2019s Monolith mission moved from Virginia to New Zealand, Rocket Lab\u2019s first flight from Launch Complex 2 at Wallops will likely launch NASA\u2019s CAPSTONE CubeSat payload to the moon.<\/p>\n

The CAPSTONE mission is scheduled for launch late this year, according to NASA and Rocket Lab.<\/p>\n

\u201cWe\u2019re excited to have another Electron on the pad for the Space Test Program,\u201d said Peter Beck, Rocket Lab\u2019s founder and CEO. \u201cWe\u2019re proud to once again demonstrate the flexible and resilient space access required by our government partners.<\/p>\n

\u201cThe Space Test Program has a long history of developing advanced space and launch capabilities that we\u2019ve all come to rely on, from global positioning systems, satellite communications, meteorological satellites, and space domain awareness capabilities,\u201d Beck said in a statement. \u201cWe\u2019re proud to support the continuation of that innovation through rapid and agile launch on Electron.\u201d<\/p>\n

The Monolith satellite will demonstrate the use of a deployable sensor that is relatively large in mass compared to the mass of the spacecraft itself, according to the Space and Missile Systems Center.<\/p>\n

The deployment of the sensor will change the satellite\u2019s dynamic properties, testing the spacecraft\u2019s ability to maintain stable attitude control, military officials said.<\/p>\n

When the military announced the Monolith mission in 2019, officials said the satellite\u2019s sensor package will collect data on space weather.<\/p>\n

Data collected from the Monolith mission will help engineers design future small satellites to accommodate deployable sensors, such as weather monitoring instruments. The Space Force said that will help reduce the cost, complexity, and development timelines of future missions.<\/p>\n

\u201cThe satellite will also provide a platform to test future space protection capabilities,\u201d the Space Force said.<\/p>\n

Rocket Lab does not plan to recover the Electron rocket\u2019s first stage booster on Thursday\u2019s mission. The company has retrieved two Electron boosters from the Pacific Ocean as engineers move toward reusing the rocket\u2019s first stage, an innovation Rocket Lab says will allow for a faster launch rate and lower costs.<\/p>\n

Rocket Lab\u2019s Electron rocket is sized to deliver small satellites to orbit, providing a dedicated ride for spacecraft that would otherwise have to fly as a lower-priority payload on a larger launch vehicle.<\/p>\n

The Electron rocket can deliver a payload of up to 440 pounds (200 kilograms) to a 310-mile-high (500-kilometer) sun-synchronous orbit, about 1% of the lift capability of a SpaceX Falcon 9 launcher. Rocket Lab sells dedicated Electron missions for as little as $7 million.<\/p>\n

On Thursday\u2019s mission, the 59-foot-tall (18-meter) Electron rocket will fly east from Rocket Lab\u2019s launch site on Mahia Peninsula in New Zealand. The rocket\u2019s first stage will burn its nine engines for about two-and-a-half minutes, followed by a six-minute firing of the second stage engine.<\/p>\n

A kick stage will finish the job of placing the Monolith spacecraft into an orbit about 373 miles (600 kilometers) above Earth at an inclination of 37 degrees to the equator. Separation of the tech demo payload is scheduled about one hour after liftoff.<\/p>\n
