This visualization shows the path the Nancy Grace Roman Space Telescope will take to the second Sun-Earth Lagrange point (L2). The visualization begins shortly after launch and concludes with Roman entering its halo orbit around L2. This view is presented in a Geocentric Solar Ecliptic (GSE) frame and includes an “L+ Days” counter.

The Nancy Grace Roman Space Telescope will help us solve some of the most profound mysteries in astrophysics, such as how the universe has evolved, its ultimate fate, and whether we are alone.

To make Roman’s sensitive measurements possible, the telescope will observe from a vantage point about 930,000 miles (1.5 million km) away from Earth in the direction opposite the Sun. At this special place in space, called the second Sun-Earth Lagrange point, or L2, gravitational forces balance to keep objects in steady orbits with very little assistance.

This extended view of the path the Nancy Grace Roman Space Telescope will take to the second Sun-Earth Lagrange point (L2) includes top-down, side, and Sun-facing views of the trajectory. The visualization is presented in a Geocentric Solar Ecliptic (GSE) frame.

This visualization includes four synchronized views of Roman’s trajectory to L2: a GSE top-down view (top-left), an Earth-centered top-down view (top-right), a GSE side view (bottom-left), and a GSE Sun-facing view (bottom-right).

Four synchronized views of Roman’s trajectory to L2 arranged in a two-by-two grid. The views show the trajectory from top-down, Earth-centered top-down, side, and Sun-facing perspectives. A central display shows elapsed launch days and changing distances between Roman, Earth, and L2.
