Late July 2026: A Fattening Moon, Edge-On Saturn, and a Meteor Shower Fighting the Light
The last ten days of July 2026 hand skywatchers a First Quarter Moon growing into the Full Buck Moon on 29 July, a nearly edge-on Saturn, evening Venus in Leo, and Delta Aquariid meteors that a near-full Moon will mostly drown out.

This Week's Sky: An Apollo-11 Twin Moon, a Stalling Mercury, and Titan Circling Saturn (July 20-24)
From July 20-24, 2026, the Metonic cycle serves up a Moon that echoes Apollo 11's landing night, Mercury stalls to end its retrograde in Gemini, and Titan hangs easily beside Saturn.

America's First Robotic Satellite Mechanic Reaches the Pad
A Falcon 9 is set to launch Northrop Grumman's MRV-1 and three Mission Extension Pods on July 21, carrying DARPA's RSGS payload — the first U.S. multi-mission robot built to inspect, repair, upgrade, relocate and refuel satellites in geosynchronous orbit.

Mauritius Signs the Artemis Accords, and Talks About the Ocean Instead of the Moon
Mauritius became the 70th Artemis Accords signatory on July 17, 2026 — the seventh African nation and the 11th country to sign this year — and framed its accession around protecting oceans and coastlines rather than lunar exploration.

Missions
Before the Metal World: Psyche's Mars Flyby Wakes Up Its Instruments
NASA released the science haul and a time-lapse from Psyche's May 15 Mars gravity assist — a free 1,000 mph boost that doubled as a full instrument checkout, including a live test of a Lawrence Livermore-built gamma-ray sensor, three years before the spacecraft reaches its metal asteroid.

The asteroid that wasn't: 1998 SH2 outed as an active comet
A NASA/JPL-led study in Nature Astronomy has reclassified near-Earth object 1998 SH2 as an active comet — now P/1998 SH2 — after tiny outgassing-driven accelerations and a faint tail gave it away during a 2025 close pass.

NASA Bolts Starlink Lasers to Orion as Artemis III Becomes a Docking Rehearsal
NASA has tapped SpaceX to mount two Starlink mini laser terminals on Orion for Artemis III, beaming 4K docking-test footage to Houston over infrared light as the mission is reframed into a 2027 low-Earth-orbit rehearsal of crewed lander rendezvous ahead of a 2028 Moon landing.

Serbia Signs the Artemis Accords, Becoming the 69th Nation — and the Latest to Straddle Two Rival Lunar Camps
Serbia became the 69th Artemis Accords signatory on July 16, 2026, and the 10th nation to join this year — while also holding membership in China's rival lunar station program, a growing pattern of dual participation.

Two Landers, Two Philosophies: Inside the Artemis III Rehearsal's Engineering Split
NASA's July 15 breakdown of the 2027 Artemis III demo reveals how far apart SpaceX and Blue Origin's test articles are: astronauts will open the hatch on Blue Moon Mark 2, but never set foot inside a 171-foot Starship that docks nose-first with a bolted-on docking system and no crew cabin.

Science & Discovery
The Meteorite That Crashed Through a New Jersey Roof Was Carrying Alien Amino Acids
Two years to the day after a fireball rattled New York City and a two-pound rock punched through a Hillsborough, NJ roof, scientists report the meteorite preserves sodium-carbonate salts and extraterrestrial amino acids brewed in briny fluids on a 4.5-billion-year-old asteroid.

The Ceiling Was an Illusion: NASA-Led Study Says Solar Storms Could Hit Earth Harder Than We Thought
A NASA-led analysis of over a million solar wind measurements finds the long-assumed "saturation" limit on geomagnetic storm intensity is a statistical artifact, not a real ceiling — meaning the worst space weather could still be ahead of us.

A One-Two Cosmic Punch: Perseverance Finds a 3.9-Billion-Year Impact Record Written Into the Rim of Jezero Crater
Perseverance has found a 245-foot rock stack on Jezero Crater's rim built by repeated ancient impacts more than 3.9 billion years ago — among the oldest terrain any Mars rover has examined.
