SpaceX Launch, Artemis Accords & a ‘5-Hour Year’ Planet: Space Roundup (July 23–24, 2025)

SpaceX’s Falcon 9 launched NASA’s TRACERS mission from Vandenberg Space Force Base on July 23 at 2:13 p.m. EDT. The Falcon 9 first stage was on its 16th flight and performed a pinpoint landing at Vandenberg, marking SpaceX’s 479th booster recovery. TRACERS, Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, consists of two 200-kg satellites to study magnetic reconnection in Earth’s magnetosphere. Five small rideshare satellites accompanied TRACERS carrying experiments such as next-generation communication terminals and Earth radiation budget sensors.

Astronomers Spot a 7-Billion-Year-Old Interstellar Comet – Could It Be the Oldest Ever Seen?

Astronomers Spot a 7-Billion-Year-Old Interstellar Comet – Could It Be the Oldest Ever Seen?

On July 1, 2025, the ATLAS telescope in Río Hurtado, Chile, detected 3I/ATLAS near Jupiter’s orbit with a hyperbolic, interstellar trajectory. 3I/ATLAS is the third interstellar object identified, following 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019. Estimates place 3I/ATLAS at 7–10 billion years old if formed in the Milky Way’s thick disk, making it possibly the oldest comet we’ve seen. Backward-orbit modeling using Gaia data and the Ōtautahi–Oxford model suggests an origin in the Milky Way’s thick disk. The nucleus is estimated to be 6–15 miles (10–24 km) across, larger than 1I/ʻOumuamua (~0.25 mile) and 2I/Borisov (~0.67 mile). It travels

Satellite Surprises and Space Shake-Ups: Weekend Roundup (July 12–13, 2025)

Satellite Surprises and Space Shake-Ups: Weekend Roundup (July 12–13, 2025)

SpaceX conducted a secret Falcon 9 launch from Florida on July 13, 2025 carrying Israel’s Dror-1 communications satellite into geostationary transfer orbit, a $200 million “smartphone in space” project that will provide Israeli communications for 15 years, with the first stage landing on a droneship for the rocket’s 13th successful reuse. China rolled out Long March-7 Y10 and Tianzhou-9 to the Wenchang launch pad on July 12, 2025 to deliver about 6.5 tons of supplies to Tiangong for the Shenzhou-20 mission, including two upgraded spacesuits and a backup Long March-7 within three months. Rocket Lab launched its HASTE suborbital rocket

Cosmic Webs, Hidden Galaxies, and Political Turbulence: This Week’s Space News Will Change How You See the Universe / Updated: 2025, July 13th, 00:01 CET

Konstantinos Migkas and team mapped a 23-million-light-year cosmic web filament with temperatures around 10 million degrees, more than 20 times the Milky Way’s size, detected via the Sunyaev-Zel’dovich effect and Planck data. Durham University simulations predict 80–100 undetected Milky Way satellite galaxies, the so‑called orphan galaxies stripped of dark matter halos, potentially solving the missing satellites problem and bolstering the ΛCDM model. Interstellar object 3I/ATLAS, the third known interstellar visitor, is over 7 billion years old and travels at about 60 km/s, observed by Zwicky Transient Facility and confirmed by the Very Large Telescope with peak brightness expected in late

Over 2,000 senior NASA employees have resigned amid budget cuts, with a potential 25% funding reduction threatening missions, while Sean Duffy, a former congressman and reality TV star, was named interim NASA administrator and serves as both NASA administrator and Secretary of Transportation. An alleged Iranian missile strike destroyed a $15 million U.S. communications radome at Al Udeid Air Base in Qatar, which housed the Modernization Enterprise Terminal (MET) for secure military communications. Russia’s secret Nivelir project drew attention after Cosmos 2558 released a small object in orbit, a move interpreted as a possible anti-satellite test signaling space-arms concerns. The

Space in Crisis and Glory: NASA Shakeup, Starlink Expansion & Buck Moon Spectacle! / Updated: 2025, July 10th, 12:01 CET

The Buck Moon on July 10, 2025 will reach peak illumination at 4:37 p.m. UTC and appear as a micromoon due to its distance, coinciding with Earth’s aphelion and a Major Lunar Standstill. President Trump appointed Sean Duffy as interim NASA Administrator in July 2025, replacing Jared Isaacman amid a backdrop of budget cuts that could eliminate more than 2,000 senior NASA jobs, including 279 at Marshall Space Flight Center. NASA’s DART mission altered Dimorphos’ orbit and ejected more than 100 boulders, adding momentum almost as large as the spacecraft itself.

Major Astronomy News in June 2025: Webb’s Exoplanet Discovery, Rubin’s First Images, Space Missions & More

The James Webb Space Telescope directly imaged a Saturn-mass exoplanet, TWA 7 b, about 0.3 Jupiter masses at 50 AU from its star, marking Webb’s first direct exoplanet discovery. The missing baryon problem was resolved using 69 fast radio bursts, showing about 76% of ordinary matter lies in hot intergalactic gas, ~15% in halos around galaxies, and ~9% in galaxies. Comet C/2014 UN271 (Bernardinelli–Bernstein), the largest Oort Cloud comet, showed CO outgassing jets at 16.6 AU with a nucleus about 140 km across, observed by ALMA.

Zombie Satellite! Defunct NASA Orbiter Emits Blazing Radio Burst After 60 Years

Zombie Satellite! Defunct NASA Orbiter Emits Blazing Radio Burst After 60 Years

Relay-2 launched January 21, 1964 from Cape Canaveral as part of NASA’s Relay program to relay television and telemetry signals and study the Van Allen belts. Relay-2 operated 1964–1967, with the first transponder failing on November 20, 1966 and the second on June 9, 1967, after which it was retired. After deactivation, Relay-2 drifted in a medium Earth orbit of roughly 1,870 by 7,600 km. On June 13, 2024, ASKAP detected a radio burst lasting less than 30 nanoseconds, peaking at roughly 300,000–350,000 Jy, spanning 695–1,032 MHz. The event was traced to Relay-2 in near-Earth space using ASKAP’s near-field timing,
