NASA launches Roman Space Telescope
NASA’s Roman telescope has begun its journey to survey the universe on a wider scale.
What happened
NASA launched the Nancy Grace Roman Space Telescope from Kennedy Space Center in Florida aboard a SpaceX Falcon Heavy. The observatory is heading to an observing point about one million miles from Earth. Its planned surveys will study dark energy, dark matter, planets, galaxies and exploding stars.
Numbers
- $4.3 billionMission cost — NASA flagship observatory
- 1 million milesDistance to observing point — From Earth
- 100 times widerField of view than Hubble — At least
- 5 yearsPlanned mission duration — Initial mission
Questions
- Why is the telescope named Roman?
- It honours Nancy Grace Roman, NASA’s first chief astronomer, a role that placed her among the agency’s early senior scientific leaders.
- How will Roman complement Webb?
- Roman will scan broad areas quickly, while Webb examines much smaller areas in detail, allowing the observatories to pursue different parts of astronomy.
- Who can use Roman’s data?
- NASA plans to share the observatory’s data globally, allowing other research teams to identify targets for more detailed follow-up observations.
- How long is the planned mission?
- The initial mission is planned to last five years, though NASA stated the telescope could operate beyond that period.
