Watch On NASA's newest space telescope is ready for its moment on stage — and soon, in space.
News conference and launch
According to NASA, briefing participants, who will discuss the telescope's progress and science plans, include:
- NASA Administrator Jared Isaacman
- Nicky Fox, associate administrator, science mission directorate
- Jamie Dunn, Roman telescope project manager
- Julie McEnery, Roman telescope senior project scientist.
The news conference will take place at NASA's Goddard Spaceflight Center in Greenbelt, Maryland, where Roman was built.
Roman is almost finished its prelaunch testing at Goddard ahead of its last big journey on Earth — a shipment to NASA's Kennedy Space Center in Florida, where the telescope will launch aboard SpaceX Falcon Heavy between autumn 2026 and May 2027.
What is Roman?
Roman, estimated to cost more than $4 billion, is a big survey telescope designed to show astronomers more about how the universe formed and evolved.

But the key difference is scope: Hubble narrows in on fine details, while Roman aims to survey the sky with a field of view 100 times larger than Hubble's.
Looking at large-scale structure of galaxies and stars is part of Roman's work, as it seeks to answer questions about how the universe formed, evolved and expanded with investigations concerning dark matter and dark energy.
Searching for exoplanets
Roman will also do a "Galactic Bulge Time-Domain Survey" to look at the central bulge of stars of the Milky Way galaxy. Investigators will mostly be looking for exoplanets, using a technique called gravitational lensing.
Very simply put, bent starlight from distant galaxies can allow objects passing in front of massive objects to be temporarily magnified and visible, thanks to how general relativity and space-time works.
This will allow Roman to hunt down exoplanets through flickers, or distortions, in starlight as planets pass in front of stars — assuming the distortions aren't due to starquakes, or some other stellar phenomena.
