Rocket Lab USA, Inc. ( RKLB ) shares are trading lower in the premarket session on Tuesday amid weakness in anticipation of U.S. tariffs, expected to begin Tuesday. 

Meanwhile, Rocket Lab announced the launch window for its 61st Electron mission, a dedicated launch for Japanese customer the Institute for Q-shu Pioneers of Space, Inc.

The mission, named “The Lightning God Reigns,” is set to lift off from Rocket Lab Launch Complex 1 in New Zealand on March 10th UTC.

This mission will deploy the QPS-SAR-9 satellite (nicknamed “SUSANOO-I”) into a 575 km circular Earth orbit, contributing to iQPS’s expanding Earth-imaging constellation.

The satellite will enable high-resolution monitoring of specific locations every 10 minutes, supporting iQPS’s efforts to build a more robust satellite network.

This launch marks the first of eight upcoming missions for iQPS over the next two years and is part of Rocket Lab’s larger effort to expand its launch capabilities. It also serves as the company’s third mission of 2025, taking its total number of satellites delivered to space to 211.

Recently, Rocket Lab’s shares experienced a sell-off after the company reported its fourth-quarter earnings last week.

Despite a 121% year-over-year revenue increase to $132.39 million, Rocket Lab posted a quarterly loss of 10 cents per share, aligning with analyst expectations.

While the company exceeded revenue estimates, its first-quarter revenue guidance of $117 million to $123 million was below the consensus forecast of $135.67 million. Additionally, Rocket Lab anticipates an adjusted EBITDA loss of $33 million to $35 million for the first quarter, which contributed to the bearish market reaction.

According to Benzinga Pro, RKLB stock has gained over 321% in the past year. Investors can gain exposure to the stock via ARK Space Exploration & Innovation ETF .

Price Action: RKLB shares are trading lower by 0.59% to $18.56 premarket at last check Tuesday.
