2026-10-22NASA Picks PRIMA, a $1.2 Billion Far-Infrared Observatory, to Lead a New Mission Class
Correction, Oct. 22, 2026: An earlier version of this article said the 2020 Decadal Survey recommended PRIMA and that PRIMA ranked highly in the survey after a long gap in far-infrared missions. NASA's release says the survey recommended establishing the Probe Explorers mission class, and that NASA selected PRIMA after evaluating concept studies; the unsupported claims about ranking and a gap have been removed.

2026-10-22Interstellar Comet 3I/ATLAS Is Drenched in Unusually Heavy Water — and That's a Clue to Its Age
Correction, Oct. 22, 2026: An earlier version of this article described the elevated methane deuteration as independent support for a low-metallicity origin; the paper says the methane-to-water deuteration ratio is not sensitive to metallicity, and the article now says so. It also contrasted 3I/ATLAS with both earlier interstellar visitors on coma spectroscopy, which the cited sources do not support; that contrast has been removed.

2026-10-22ESA and ISRO Extend Their Partnership to 2032 — and Widen It to Space Weather and Human Exploration
Correction, Oct. 22, 2026: An earlier version of this article said ESA Director General Josef Aschbacher and ISRO Chairman V. Narayanan personally signed the extension, and that the expanded scope builds directly on a 2025 Joint Statement of Intent and gives it a formal legal home. The sources say the agencies signed an exchange of letters, and that the agencies had expressed their intention to deepen cooperation through the 2025 statement while the 2026 agreement adds human and robotic exploration. The article now says that.

2026-10-22Webb Finds Ammonia — and an Unexpected Chill — in the Atmosphere of a Saturn-Mass Planet Circling a Red Dwarf
Correction, Oct. 22, 2026: An earlier version of this article described a roughly 250°F temperature as a measured value, attributed the ~800°F figure to planets in HATS-6 b's class rather than to HATS-6 b itself, and suggested equilibrium-temperature estimates across the exoplanet catalog may need revisiting. The 250°F figure was an early analysis result that the researchers call physically improbable; the article now says so, and limits the broader point to the release's concern about reading atmospheres of planets orbiting small, active stars.

An earlier version of this article said the 2020 Decadal Survey recommended PRIMA and that PRIMA ranked highly in the survey after a long gap in far-infrared missions. NASA's release says the survey recommended establishing the Probe Explorers mission class, and that NASA selected PRIMA after evaluating concept studies; the unsupported claims about ranking and a gap have been removed.

2026-10-22Final-Minute Scrub Holds Up SDA's Fourth Tranche 1 Launch; Falcon 9 Now Aiming for Oct. 10 at the Earliest
Correction, Oct. 22, 2026: An earlier version of this article reported that the next launch attempt was set for Thursday, Oct. 8. Spaceflight Now reported on Oct. 7 that SpaceX was targeting no earlier than Saturday, Oct. 10, and the headline, summary and text now say so.

2026-10-22Jupiter's Moons Start Eclipsing Each Other: How to Watch the 2026-27 Mutual Event Season Before Dawn
Correction, Oct. 22, 2026: An earlier version of this article attributed to NASA's Jupiter moons page a statement that Simon Marius observed the moons around the same time and proposed their current names in 1614. The NASA page does not say that; the article now says only that NASA reports Galileo first observed the moons in 1610.
-
2026-10-22Roman Space Telescope's Three Ground Stations Pass Peak-Rate Data Test Ahead of 2027 Science Start
Correction, Oct. 22, 2026: An earlier version of this article said Roman had already settled into its working position near the Sun-Earth L2 point. It is still traveling toward L2 and is due to enter a halo orbit there in early December; the article now says so.

2026-10-22Saturn at Opposition, Then the Moon Swallows Jupiter: A Double Header for Early October
Correction, Oct. 22, 2026: An earlier version of this article said EarthSky also put Saturn's evening visibility at until March 2027. EarthSky does not give that date; the March 2027 timing comes from NASA JPL's Night Sky Network listing alone, and the sentence has been removed.
-
2026-10-22Astronomers Find the Milky Way's First 'Microblazar' — and Its Jet Points at Us
Correction, Oct. 22, 2026: An earlier version of this article described the black hole as likely only a handful of solar masses. Phys.org gives it as about 10 times the mass of the sun, orbiting a hot, massive star, and the article now says so.
-
2026-10-22China Narrows Tianwen-3 Mars Sample-Return Landing Zone to Eight Candidates in Hunt for Ancient Life
Correction, Oct. 22, 2026: An earlier version of this article said the selection process was described "earlier this year" (it was July 2025), said the latitude requirement alone cut the candidate list from 80-plus to 19 and gave a thermal, solar and landing-physics rationale (the source says the selection balanced engineering constraints and scientific priorities, with 17 to 30 degrees north as one engineering limit), and referred to a launch window opening in late 2028 (the source says a launch planned for around 2028). The article now reflects the source.

2026-10-22Artemis II Science Data Goes Public: Impact Flashes, a Rainbow Moon and 54 Minutes of Eclipse
Correction, Oct. 22, 2026: An earlier version of this article said Space.com gave smaller figures than NASA for the first batch of data. Only Space.com's image count (996) is smaller; its data volume (814 GB) and audio (521 minutes) are consistent with or slightly above NASA's figures. The article now reports Space.com's figures as stated.
-
2026-10-22VIPER Is Built, Crewed Rovers Face Design Reviews: NASA's Moon Base Rover Roadmap Takes Shape
Correction, Oct. 22, 2026: An earlier version of this article presented the one-year, multiple-lunar-night survival requirement as a design requirement for the FLIP rover. Space.com attributes it to the challenge NASA has given Astrolab for its crewed lunar terrain vehicle, and the article now says so. A sentence saying FLIP tests survival of lunar nights over months was also revised, as the sources do not support it.

2026-10-22Coronal-Hole Wind and a Flaring Sunspot Set Up a G1 Aurora Window for Oct. 19-21
Correction, Oct. 22, 2026: An earlier version of this article said EarthSky added that a slow Oct. 16 CME may also arrive. EarthSky's report does not say that; it says analysts identified no Earth-directed CMEs in the period, and the sentence has been removed.
-
2026-10-22NASA's SPEARS Solid-State Battery Cells Hold Up in Moon-Grade Cold, With Limits
Correction, Oct. 22, 2026: An earlier version of this article said the detailed data was not public yet and that readers would have to wait for a fuller publication. NASA's Technical Reports Server record for the American Chemical Society presentation is marked for public distribution and lists a downloadable PDF. The article now says so; we have not reviewed the file.
-
2026-10-22SpaceX's Bandwagon-5 Rideshare Will Carry Two Reentry Capsules Into Orbit
An earlier version of this article gave the Oct. 20 launch time as a one-hour window opening at 6:30 a.m. EDT (1030 UTC). Spaceflight Now gives liftoff at 7:04 a.m. EDT (1104 UTC), and the article now says so.

2026-10-22A Dead Soviet Satellite Breaks Apart Again as ESA Warns Low Earth Orbit Is Heading for Runaway Growth
Correction, Oct. 22, 2026: An earlier version of this article attributed to ESA a statement that the remaining debris-mitigation options are getting more demanding. ESA's report does not say that; the article now says only that adoption of mitigation measures is rising but needs to be faster, more consistent and more reliable.

2026-10-22Mercury Reaches Greatest Eastern Elongation on October 12, and the Southern Hemisphere Gets the Best View of the Year
Correction, Oct. 22, 2026: An earlier version of this article said Star Walk advises that binoculars may help find Mercury. Star Walk only warns to wait until the Sun is fully below the horizon before using binoculars and never to sweep them near the Sun; the article now says that.

2026-09-29Artemis Accords Reach 76 Signatories as Four Nations Join in Five Days
An earlier version of this article's headline said four nations joined the Artemis Accords in eight days. Signing dates reported by Nature World News run from Sept. 21 to Sept. 25, so the headline now says five days.
-
2026-09-29Starliner Gets a Reset: An Uncrewed Flight This Winter, Astronauts by 2028, and Vulcan Certification Work
An earlier version of this article said the 2028 crewed Starliner-2 flight depends on certifying the Vulcan rocket, and gave an incomplete account of the thruster cause. Space.com reports Starliner-1 through -4 will fly on Atlas V and only Starliner-5 and -6 move to Vulcan, and NASA attributes the thruster issues to operation outside engineering qualification, with thermal environment and design features as contributing factors.

2026-09-29NISAR's Radar Eyes Track a Kamchatka Volcano Erupting After 475 Years
An earlier version of this article said NISAR was in position to watch the Krasheninnikov eruption begin and tracked it for eight months. JPL reports NISAR's first image of the volcano was on December 25, 2025, and the time-lapse runs from December 2025 through mid-August 2026. The article also no longer attributes to JPL statements about Kamchatka's ground monitoring or scientists' views on the quake link, nor describes the mission as a year into full operations. It also now says JPL likely places the northwest lava flow before NISAR's first observations.
What does not count as a correction
Stories develop after the first report. When later events change the picture we publish a follow-up article rather than rewriting the original; the original stays as the record of what was known on its date.
