NASA’s Nancy Grace Roman Space Telescope was launched aboard a Falcon Heavy from Florida, USA at 7:26 am on August 30, and separated from the rocket about 58 minutes later and began flying on its own. Roman will move into orbit around the Sun-Earth L2, about 1.6 million kilometers from Earth, for about three months.<\/p>\n

This does not mean that we have already discovered dark energy or exoplanets. Launch and initial separation have been completed, but telescope inspection and orbital entry remain, and actual large-scale scientific observations will begin after commissioning.<\/p>\n

what fired<\/h2>\n

Roman is NASA’s next-generation space telescope with a primary mirror with a diameter of 2.4 meters. The size of the mirror is similar to that of Hubble, but the area of \u200b\u200bthe sky that the wide-field observation device can see at once is about 100 times larger than the Hubble infrared camera. The key is to statistically compare the shapes and distances of billions of galaxies by scanning the sky at the same depth faster.<\/p>\n

How far have we come since launch?<\/h2>\n

According to NASA’s live broadcast, the Falcon Heavy passed the maximum dynamic pressure section and stage separation and ejected Roman following a final upper engine burn. After separation, the deep space communication network took over communications. The current expression of success refers to the launch and separation stage, and does not refer to the overall mission success, including L2 arrival and observation performance verification.<\/p>\n

Why do you need L2?<\/h2>\n

Around Sun-Earth L2, the Sun, Earth, and Moon are on the same side of the telescope, so light and heat can be reliably blocked by a light shield. Rather than staying at a single point, Roman orbits in a large orbit around L2. Because it is about 1 million miles, or 1.6 million kilometers, from Earth, there are no plans for people to go there right away to repair it.<\/p>\n

What are you planning to see?<\/h2>\n

Roman uses broad measurements of galaxy distribution and supernovae to test models of cosmic expansion and dark energy. We will repeatedly observe the center of the galaxy to find thousands of exoplanets using gravitational lenses, and we will also test direct observation with starlight obscured by demonstrating coronagraph technology. The estimated number of discoveries is a projection based on mission design and is not a guarantee of actual results.<\/p>\n

What is the next confirmation schedule?<\/h2>\n

In the future, we will check the status of solar panels, antennas, and thermal control, and calibrate the trajectory during flight. Approximately three months later, it will enter orbit around L2 and then undergo instrument alignment and calibration. Communications\/orbit updates and first light releases from NASA’s Roman Mission Blog are the next key checkpoints.<\/p>\n
