Where is the Roman telescope going?
The Nancy Grace Roman Space Telescope lifted off from Kennedy Space Center on Sunday morning. By 7:58, it had separated from its SpaceX rocket and began its journey to the second Sun-Earth Lagrange point. That destination sits 1.6 million kilometres from Earth — a distance where an observatory can look out into the deep to map galaxies and measure dark energy.[1]
What makes its field of view different?
Every telescope is a time machine, and Roman's power lies in how much of the sky it can capture at once. NASA puts its field of view at least 100 times wider than Hubble's. Where older instruments were built for a narrower gaze, this one will run wide surveys to measure the dark energy pushing everything apart. We are sending an eye wide enough to read the history of expansion.[1]
Which signals will the ground networks track next?
Within half an hour of separation, the observatory's six panels were due to unfold, serving both as a power supply and a sun shield for the instruments. Tracking now passes to ground stations run by NASA, the European Space Agency and the Japan Aerospace Exploration Agency. They will listen in the dark as Roman travels; if it arrives at its station and calibrates, the first true survey measurements will follow.[1]
