Project
NASA infrared space telescope with Hubble-class resolution over a field of view about 100 times larger, surveying the sky from near Lagrange Point 2.
NASA's next flagship survey telescope will watch hundreds of millions of stars for one-off gravitational blips. That is how you count Earth-mass planets you will never get to look at a second time.

Elias 2-24 b sits in a disk gap 55 times Earth's distance from its star, where formation models ask for at least five million years to build a Jupiter. Keck coronagraph images from 2018 and 2020 put it under a million years old.

NASA's Roman Space Telescope held its pointing steady to better than 1/100,000 of a degree in September tests, for up to eight hours in coronagraph mode. Its coronagraph has also imaged stars, but its starlight suppression is still untested.

PRIMA, a 1.8-metre far-infrared telescope managed by JPL, moves into preliminary design with a project cost ceiling of $1.2 billion that excludes launch, a 2033 launch target and a confirmation review still ahead.
Reality
NASA says the Wide Field Instrument and the coronagraph are both working in space. The two published accounts of the milestone disagree about when science observations start and how long the mission runs.
Reality
A Copenhagen-led team reports in Nature a faint trail of tidally stripped stars inside the ultra-diffuse galaxy UGC9050-Dw1, where the mass it implies agrees with earlier estimates for the same galaxy.
Reality
NASA pointed the telescope at galaxy cluster MACS J0417 on September 19 to catch a second appearance of supernova Athena, predicted before early March 2027, and the timing would constrain both the cluster's mass and the expansion rate.
Reality
The Nancy Grace Roman Space Telescope should return its first images in early 2027, and its Wide Field Instrument will deliver them over at least 100 times the sky Hubble frames in a single pointing.
Reality
Ten current and former staff told Scientific American that NASA's Goddard Space Flight Center no longer has the people or the equipment to build a telescope like Roman. NASA says flagship missions remain a core Goddard capability.
Reality
The Wide Field Instrument passed its first in-flight tests of detectors, calibration source, filter wheel and focus, and NASA says first science images are still expected by early 2027 with months of commissioning left.
Reality
NASA now says the Nancy Grace Roman Space Telescope has propellant for at least 22 years against a 10-year design life, with the extra time coming from three savings of about four years each. Two of the three are already banked.
Reality
NASA says the Roman Space Telescope now has propellant for at least 22 years of science against a planned decade, a margin built from a spacecraft that launched light and course-correction burns that came in under their allocations.
Reality
NASA's Roman Space Telescope, launched Aug. 30, 2026, will find planets in the brief brightening of background stars. That method reaches the cold, wide orbits current catalogs barely sample.
Reality
NASA's Artifact InSPECtor asks the public to mark cosmic-ray hits, stray glints and electronics quirks in Euclid's spectrograph data, and those classifications will be used to sharpen the software built to remove them.
Reality
The five-year survey covers about 75 percent of the sky and roughly 4 billion objects, and what shows it has landed as a product is the 1,800 papers already citing it.
Reality
Every dollar of the $4.3bn observatory rode one vehicle from one provider, which is the concentration number to carry into any space-sector position, whatever the science eventually turns out to be worth.
Reality
The telescope's first proposal round came back twelvefold oversubscribed. Hubble and Webb have posted the same result for years: the figure describes how much telescope time exists, not Roman's standing in particular.
Reality
The experimental instrument riding alongside Roman's survey camera carries the first deformable mirrors NASA has flown, and its science teams have pre-committed to a test that tells them whether the fault is theirs.
Reality
Before the telescope's Aug. 30 launch, ground software named ROSALIA already helps decide which targets get scheduled and what the darkest pixels are allowed to mean.
Reality
NASA's Nancy Grace Roman telescope can launch as soon as August 30 with Hubble-class resolution across a field about 100 times larger. Those pixels have to go somewhere.
