Astronomical observatories operating in space, such as Hubble, Webb, and Roman, used to study distant objects from vantage points like Lagrange Point 2.
L3Harris will build the Engineering Test Unit for NASA's all-glass LISA telescope, the agency's last pre-flight unit before flight hardware. NASA is supplying the telescopes and laser system for the ESA-led gravitational-wave observatory, due to launch in the mid-2030s.
Reality
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.

Pablo Santos-Sanz's team used the James Webb Space Telescope to find Chariklo's inner ring 42% more opaque and its outer ring barely visible. Occultations are rare, so for now the team can show that the rings changed but not why, or how long they will last.
Reality
JWST found water-altered clay minerals on two of Neptune's small inner moons and its rings, with no water ice. The likely source is the shattered interior of a much larger lost moon.
Reality
Saturn's northern hexagon has looked the same for more than 40 years, so a second polygon that only shows up in images from 2023 onward hands atmospheric modellers a formation they can watch happen rather than a finished structure to explain.

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
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
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
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
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.
