The Nancy Grace Roman Space Telescope has begun its journey into space after years of uncertainty over its funding, including repeated proposals during Donald Trump's presidency to cancel the mission.
The observatory launched on August 30 aboard a SpaceX Falcon Heavy from NASA's Kennedy Space Center in Florida. Shortly after the successful launch, NASA Administrator Jared Isaacman received a call from US President Donald Trump, who congratulated the team and praised the mission.
The moment was notable because Trump's administration had previously sought to cut or cancel funding for the telescope.
A MISSION THAT SURVIVED MULTIPLE FUNDING THREATS
During Trump's first presidency, his administration proposed cancelling the Roman telescope in three separate budget requests between 2019 and 2021. Congress rejected those proposals and continued funding the mission.
The telescope faced another funding threat in 2025, when proposed White House budget cuts targeted NASA's science programmes. The proposed reductions raised concerns that Roman could once again be cancelled or delayed.
Congress ultimately rejected those cuts and approved around $24.4 billion for NASA for fiscal year 2026, allowing the Roman mission and other major science programmes to continue.
ROMAN'S JOURNEY INTO DEEP SPACE
The telescope has now started its journey towards the second Sun-Earth Lagrange point, known as L2, around 1.5 million kilometres from Earth.
Roman carries a 2.4-metre primary mirror, comparable in size to the Hubble Space Telescope's mirror. Its Wide Field Instrument can observe an area of the sky at least 100 times larger than Hubble's field of view in a single observation.
The observatory is designed to survey vast regions of the universe and help scientists investigate dark energy and dark matter, understand how galaxies evolved and search for planets beyond our solar system.
Its large-scale surveys are also expected to generate enormous amounts of astronomical data that could support research across multiple areas of space science.
FROM CANCELLATION THREATS TO CONGRATULATIONS
The successful launch marks a striking turnaround for a mission that repeatedly faced questions over its future.
Instead of being cancelled or indefinitely delayed, the Roman telescope has now left Earth and begun its scientific journey.
Trump's post-launch congratulations therefore came after years in which his administration had sought to reduce or eliminate funding for the very mission now being celebrated.
For Roman, however, the funding battles are now behind it. Its next challenge is to reach L2, begin operations and use its exceptionally wide view of the cosmos to answer some of astronomy's biggest questions.
