Replace 7:34 p.m. EDT: Rocket Lab confirmed deployment of the NEONSat-1 payload.
Rocket Lab accomplished its fifth launch of the yr, which was a rideshare mission between the Korea Superior Institute of Science and Know-how (KAIST) and NASA. This was additionally the corporate’s forty seventh Electron launch thus far.
Liftoff from Launch Complicated 1’s Pad B in New Zealand occurred at 10:32 a.m. NZT on April 24 (6:32 p.m. EDT, 2232 UTC on April 23). The staff labored via a floor methods concern that delayed liftoff by about 17 minutes.
Rocket Lab is not going to try to get better the primary stage booster following stage separation on this flight.
The first payload on the mission was the NEONSat-1, an Earth statement satellite tv for pc that’s designed with “a high-resolution optical digital camera designed to observe for pure disasters alongside the Korean Peninsula by pairing its pictures with synthetic intelligence,” in response to KAIST.
NEONSat-1, which was developed for the Satellite tv for pc Know-how Analysis Heart (SaTReC) at KAIST, was deployed right into a 520 km (323.1 mi) round Earth orbit. Because the identify suggests, it’s the first satellite tv for pc within the New-space Earth Commentary Satellite tv for pc program, which is funded by the Korean authorities’s Ministry of Science and ICT (MSIT). Observe-on satellites are anticipated to be launched in 2026 and 2027.
One down, one to go.

Come sail away
Additionally sharing a trip to house is NASA’s Superior Composite Photo voltaic Sail System (ACS3). This can be a expertise demonstration, which is able to harness the ability of daylight via the spacecraft’s photo voltaic sail propulsion system.
After the deployment of NEONSat-1, the Electron’s Kick Stage will reignite to boost its apogee to 1,000 km (621.4 mi). There will probably be a 3rd burn to circularize the orbit earlier than the ACS3 is deployed utilizing Exolaunch’s EXOpod Nova deployer.
The spacecraft itself relies round a twelve-unit (12U) CubeSat bus, the dimensions of a microwave oven, which was constructed by Kongsberg NanoAvionics. It is going to deploy booms which can be made from a mix of versatile polymer and carbon fiber to a size of about 30 toes (9.1 meters).
It takes about 25 minutes for the photo voltaic sails to completely deploy, after which it’s going to measure 80 sq. meters (~860 sq. toes), which is concerning the dimension of six parking spots, in response to NASA. The company mentioned cameras mounted onto the spacecraft will be capable of seize deployment, permitting researchers to get a visible understanding of how properly the capabilities carried out.
As soon as deployed, NASA mentioned it may be seen within the sky, underneath the correct lighting circumstances. It’s anticipated to be “as shiny as Sirius, the brightest star within the night time sky.”
“Seven meters of the deployable booms can roll up right into a form that matches in your hand,” mentioned Alan Rhodes, the mission’s lead methods engineer at NASA’s Ames Analysis Heart in California’s Silicon Valley in a press release. “The hope is that the brand new applied sciences verified on this spacecraft will encourage others to make use of them in methods we haven’t even thought-about.”
Researchers consider the booms could be constructed to help photo voltaic sails as giant as 500 sq. meters (~5,400 sq. toes) with future designs going as giant as 2,000 sq. meters (~21,500 sq. toes), which is about half the dimensions of a soccer discipline.
“This expertise sparks the creativeness, reimagining the entire thought of crusing and making use of it to house journey,” mentioned Rudy Aquilina, undertaking supervisor of the photo voltaic sail mission at NASA Ames in a press release. “Demonstrating the skills of photo voltaic sails and light-weight, composite booms is the subsequent step in utilizing this expertise to encourage future missions.”
