The Roman Space Telescope has begun its three-month journey to the Sun-Earth Lagrange Point 2, where it is currently undergoing system calibration.

The Roman Space Telescope is currently traveling to the Sun-Earth Lagrange Point 2 (L2), a journey expected to take three months. During this transit, the observatory is undergoing a commissioning phase to activate, calibrate, and prepare its systems for future science operations.

Deployment and System Activation

Approximately one hour and 23 minutes after launch, the telescope began unfolding from its compact launch configuration. The solar panels and sunshade have already deployed to provide power and thermal protection. In the coming days, the team plans to swing out the antenna and move the aperture cover into place to reveal the primary mirror.

Orbiting at Lagrange Point 2

Once it reaches L2, the telescope will enter a stable halo orbit. This location allows the observatory to maintain alignment with Earth while using minimal fuel. The position provides a clear, unobstructed view of the sky and minimizes thermal interference from the Sun, Earth, and Moon, which is critical for the telescope's infrared observation capabilities.
