NASA’s Nancy Grace Roman Space Telescope has begun a three-month journey covering roughly one million miles as it travels toward its final orbit. The observatory lifted off at 7:26 a.m. EDT Sunday aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Once operational, Roman will combine sharp infrared vision with an unusually wide view of the sky. That combination will allow astronomers to examine enormous regions of space while also looking far back into cosmic history. Among its primary goals are studying dark matter, dark energy, and worlds outside of our solar system, known as exoplanets. Its sweeping observations are also expected to support many discoveries beyond those central objectives.
"Roman is exactly the kind of success story we want to see across NASA," said NASA Administrator Jared Isaacman. "Delivered ahead of schedule and on budget, this mission reflects more than a decade of dedication from the NASA workforce and our industry partners. Now, Roman will give us a new atlas of the universe, push the boundaries of discovery, and demonstrate what is possible when America’s space program pairs bold ambition with disciplined execution."
Controllers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, started receiving telemetry from Roman just seven minutes after launch. Falcon Heavy operated as planned and separated from the observatory 31 minutes after liftoff. After detaching from the rocket’s center core, the two boosters returned safely to the launch site, where they can be refurbished.
"Roman will be a discovery machine that will bring us closer than ever before to answering humanity’s most profound questions about our cosmic history," said Nicky Fox, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. "With its large field of view and fast survey speeds, Roman will usher us into a new era of discovery and make the invisible visible, setting the foundation for humanity’s search for life beyond our solar system."
During the first part of the mission, Roman communicates with controllers using the Near Space Network, a system of ground stations and relay satellites that handles tracking, telemetry, and commands. Roughly 70 minutes after launch, communications shift to NASA’s Deep Space Network, which will help guide the observatory toward the second Sun-Earth Lagrange point, or L2, about one million miles from Earth.
L2 is a region where the gravitational influences of the Sun and Earth allow spacecraft to maintain a relatively stable position with limited fuel use. Roman will first communicate through the Canberra Deep Space Communication Complex in Australia. Approximately six hours later, communications will transfer to the Madrid Deep Space Communication Complex in Spain and then to the Goldstone Deep Space Communication Complex in California. Together, these facilities will help maintain continuous contact with the spacecraft during its journey.
One hour and 23 minutes after launch, the Roman team confirmed that the observatory’s solar panels and lower instrument sun shade had deployed successfully.
Over the next several days, Roman’s high-gain antenna and visor-like deployable aperture cover will also deploy. Mission controllers will carry out the first of two course corrections, and Roman’s Coronagraph Instrument will be switched on.
🇰🇷 한국어 요약
NASA의 나신 그레이스 로마(Roman) 우주망원경은 플로리다주 케네디 우주센터에서 스페이스X 팰컨 헤비 로켓에 실려 발사되었습니다. Roman은 약 100만 마일, 우리 기준으로 약 160만 킬로미터 거리를 여행해 지구와 태양 사이의 안정적인 관측 위치인 L2(라그랑주점)에 도착할 예정입니다. 이번 기사의 핵심은 Roman이 단순한 우주망원경이 아니라, 우주를 넓게 그리고 빠르게 스캔하는 ‘탐사 기계’라는 점입니다. Roman은 날카로운 적외선 관측 기능과 아주 넓은 시야를 함께 갖추고 있어, 거대한 은하 영역을 한 번에 조사하면서 우주 초기까지 거슬러 볼 수 있습니다. 그 주요 목표는 암흑물질, 암흑에너지, 그리고 외계행성 연구입니다. 발사 후 7분 만에 지상 통제센터에서 Roman의 신호를 받아 확인했고, 로켓과 분리된 뒤 통신은 근우주망에서 심우주망으로 전환됩니다. 호주, 스페인, 미국 캘리포니아의 심우주통신국이 차례로 이어받아 우주선의 연락을 유지합니다. 이후 태양광 패널, 그늘막, 안테나, 그리고 별빛을 가려 행성을 직접 촬영하는 Coronagraph Instrument가 차례로 작동 준비를 마치면, Roman은 보이지 않던 우주의 규칙을 찾아내는 새로운 지도를 만들어 갈 것입니다.
