Rocket Lab prepares for next launch, moves closer to Electron reusability

rocket-lab-neonsat-1-mission

Rocket Lab is readying for its next launch no earlier than April 24th from Launch Complex 1 on the Mahia Peninsula in New Zealand.

The mission, Beginning of the Swarm, will feature two payloads being deployed to completely different orbits.

The primary payload for this mission, NEONSAT-1, is for the Korea Advanced Institute of Science and Technology and Satellite Technology Research Center and is an Earth observation satellite with a high-resolution camera to help monitor the Korean peninsula during natural disasters. This will be the first of an 11-satellite constellation for the country.

NEONSAT-1 will be deployed into a 520km circular Earth orbit.

The secondary payload is NASA’s Advanced Composite Solar Sail System, or ACS3. This cubesat is meant to test new materials used on deployable booms that will hold a solar sail. Once fully unfurled, it will measure approximately 30 feet per side.

ACS3 will be deployed into a 1000km circular Earth orbit after Rocket Lab’s Curie kick stage performs an orbit-raising maneuver and then once deployed, the kick stage will ignite once more to lower its orbit to ensure a quicker re-entry into the atmosphere and not turn into space debris.

Rocket Lab moves closer to first stage re-usability

Rocket Lab announced today at the Space Symposium in Colorado that they have brought a previously flown Electron first stage back into the production line.

The first-stage tank has already undergone extensive testing, including holding excess pressure for more than 20x a normal flight duration, leak checks, and structural testing, which allowed it to re-enter the production line.

This specific first stage flew the Four of a Kind Mission on January 31st. Rocket Lab did not indicate if any of the Rutherford engines that flew on that mission will be re-used or if they will be all new. The company has also yet to disclose which payload will be launched using the flight-proven first stage.

Rocket Lab is certainly making strides towards full first-stage reusability on Electron and also gathering valuable data that will help them recover Neutron, their future medium-lift rocket.

Do you think Rocket Lab will be flying re-used Electron stages frequently by the end of this year, or could they run into issues as they progress towards that goal?

MAHIA, New Zealand--(BUSINESS WIRE)--Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a global leader in launch services and space systems, today deployed two satellites to two different orbits approximately 500km apart on its 47th Electron mission.

The “Beginning Of The Swarm” (B.T.S.) mission lifted-off from Rocket Lab Launch Complex 1 in Mahia, New Zealand at 10:32 NZST on April 24th, 2024 with payloads for the Korea Advanced Institute of Science and Technology (KAIST) and NASA. The primary payload, NEONSAT-1 by KAIST, was first deployed by Electron to a 520km circular Earth orbit before Electron deployed NASA’s Advanced Composite Solar Sail System to a higher circular orbit at 1,000km.

NEONSAT-1 will perform Earth-observation of the Korean Peninsula for KAIST, which will then pair the satellite’s data with artificial intelligence to monitor for natural disasters in the region. NEONSAT-1 is the first of 11 satellites for KAIST’s planned constellation to image the Korean Peninsula several times daily.

The second mission deployed today was NASA’s Advanced Composite Solar Sail System, which is a technology demonstration of new materials that use sunlight to propel a spacecraft. Much like a sailboat is powered by wind pushing against a sail, solar sails employ the pressure of sunlight for propulsion to move around. This mission plans to test how well new composite booms unfurl the sail from the spacecraft – which is about the size of a toaster – to an area about the size of a small apartment. Data from this mission will be used for designing future larger-scale composite solar sail systems for space weather early warning satellites, asteroid and other small body reconnaissance missions, and missions to observe the polar regions of the sun.

The capability to deploy two satellites more than 500km apart on the same launch is enabled by Electron’s Kick Stage, a small stage with engine relight capability to enable last-mile delivery. After deploying NEONSAT-1, Electron’s Kick Stage completed multiple in-space burns of its Curie engine to raise its apogee and circularize its orbit before deploying the Advanced Composite Solar Sail System spacecraft. The Kick Stage then completed a fourth and final engine light to perform a deorbit maneuver that returned the stage closer to Earth to speed up its eventual deorbit, helping to reduce long term orbital debris.

Today’s successful mission was Rocket Lab’s fifth launch of 2024, continuing Electron’s streak as the United States’ second-most frequently launched rocket annually.

Details of Rocket Lab’s next Electron mission will be announced shortly.

S. Korea successfully launches first nanosatellite for satellite constellation

South Korea’s first nanosatellite for mass production was launched into orbit at approximately 7:32 a.m. (KST) on April 24, lift aboard Rocket Lab’s “Electron” rocket from a spaceport in Mahia, New Zealand. It was initially scheduled to launch at 7:08 a.m. but was delayed due to a possible collision with another spacecraft. Another delay occurred mid-launch due to a problem with the ground system.

Despite these setbacks, the rocket proceeded successfully, achieving separation at 7:41 a.m., roughly nine minutes after launch. The final catapulting of the satellite was also succeeded at around 8:22 a.m., about 50 minutes post-launch. Communication with the Korea Aerospace Research Institute’s ground station in Daejeon was made at around 11:56 a.m., marking the pivotal moment to determine the launch’s success.

This nanosatellite for satellite constellation, developed by the state-run Korea Advanced Institute of Science and Technology (KAIST) Satellite Research Center, is to provide precise surveillance of the Korean Peninsula and its surrounding waters, facilitating swift responses to national security threats and disasters. It is the first in a constellation of 11 satellites. It is an Earth observation satellite equipped with an electro-optical camera capable of 1-meter resolution for black and white images and 4-meter resolution for color images at an altitude of 500 kilometers. Following this year’s initial launch, five more satellites are scheduled for deployment in June 2026, with five additional sets for launch in September 2027. With varying orbital inclinations, capturing images of the Korean Peninsula three times daily will be possible.

The comprehensive mission of the first nanosatellite of the constellation is slated to commence in November this year, subject to performance evaluations conducted by the Korea Aerospace Research Institute and the Svalbard Satellite Station in Norway to ensure regular operation during its designated orbit. Subsequently, operations will be managed by the Korea Satellite Operations Center in Jeju for three years.
