🔭 DISCOVERIES

PSYCHE DELIVERS MARS FLYBY SCIENCE

• NASA's Psyche spacecraft used its May 15, 2026 Mars gravity assist to gain speed and tilt its trajectory toward metal-rich asteroid Psyche, arriving in 2029; flyby data and a time-lapse video are now public. ^[1]
• Psyche's multispectral imager captured an enhanced-color mosaic of the Martian surface on May 15, with the spacecraft traveling northeast to southwest across Mars during the pass. ^{[2] [10]}
• ESA's Mars Express independently imaged the Psyche spacecraft during the flyby, providing a rare two-spacecraft view of the encounter.
• A composite time-lapse released July 17 shows Mars's crescent growing in Psyche's cameras from May 2 through May 15 as the spacecraft closed in. ^[3]

NEW EXOPLANETS CONFIRMED

• NASA confirmed TOI-1533 b, a Neptune-like planet of 28.1 Earth masses orbiting a K-type star every 3.6 days at 0.0445 AU; discovery announced 2026. ^[5]
• TOI-1533 c, also Neptune-like at 36.6 Earth masses, orbits the same K-type star every 8.1 days at 0.076 AU; discovery announced 2026.
• TOI-791 b (9.5 Earth masses, 139.3-day orbit) and TOI-791 c (18.6 Earth masses, 232-day orbit) are two Neptune-like worlds around an F-type star, both announced in 2026.
• TOI-6884 b is a super-massive gas giant of 26.32 Jupiter masses orbiting an F-type star every 4.8 days at 0.0629 AU; discovery announced 2026.

CHANDRA AND IXPE AT THE LIGHTHOUSE NEBULA

• A composite image released July 9, 2026 combines X-ray data from NASA's Chandra X-ray Observatory and IXPE (Imaging X-ray Polarimetry Explorer) to study the rapidly spinning, strongly magnetized pulsar inside the Lighthouse Nebula.

VIKING 50TH ANNIVERSARY GALLERY

• NASA highlighted the Viking 1 Mars landing of July 20, 1976, marking nearly 50 years since the first photograph was returned from the surface of another planet.

🛰️ MISSIONS

PSYCHE EN ROUTE

• The Psyche team confirmed post-flyby instrument checkout using Mars as a stand-in target for the metal-asteroid science operations planned for 2029 arrival. ^[1]
• Both Chandra and IXPE continue joint X-ray observations of compact objects, with the Lighthouse Nebula pulsar study serving as the latest published result.

ISS EXPEDITION 74

• Crew swap activities are underway aboard the International Space Station as three newly arrived crewmates continue adaptation to microgravity while a departing Expedition 74 trio prepares to return to Earth.
• Scientific operations including human research studies are back in full swing aboard the station following the handover period.

ASTRONAUT HEALTH

• NASA's Office of the Chief Health and Medical Officer launched a working group in April 2026 to assess venous thromboembolism (VTE) risk, incorporating new data on altered blood-flow patterns observed in a cohort of astronauts.
• NASA's Translational Research Institute for Space Health (TRISH) is currently accepting proposals specifically targeting VTE blood-clot formation during spaceflight.

ARTEMIS ACCORDS

• Mauritius officially became the 70th signatory of the Artemis Accords on July 17, 2026, making it the seventh African nation to join the global framework for responsible space exploration.

☀️ SPACE WEATHER

HIGH-ENERGY ELECTRONS — ONGOING ALERT

• NOAA SWPC issued a continued ALTEF3 alert at 15:26 UTC on July 18, 2026: the 2 MeV integral electron flux has exceeded 1,000 pfu since July 17 at 17:50 UTC, as measured by GOES-18, with yesterday's peak reaching 1,085 pfu at 15:20 UTC on July 18. ^[4]
• Elevated high-energy electron flux poses enhanced charging risks for satellites in geostationary and high-Earth orbits. ^[4]

PRIOR ELEVATED ACTIVITY (CONTEXTUAL)

• On July 10, 2026, GOES-19 first detected the 2 MeV electron flux crossing 1,000 pfu (yesterday's max at that time was 767 pfu), indicating this elevated-flux episode has persisted for over a week.
• Late June saw an X1.1 solar flare peak at 20:50 UTC on June 30 from region N18W18, rated R3 (Strong) radio blackout, accompanied by a Type II radio emission at 1,496 km/s and a Type IV burst, suggesting a fast CME was launched.
• That CME arrival drove geomagnetic conditions to G1 (Minor) on June 30 to July 1, with a subsequent G2 (Moderate) storm watch issued for July 3, 2026.

📄 RESEARCH

T CORONAE BOREALIS — WHEN WILL IT BLOW?

• A new arXiv paper combines three independent constraints — historical recurrence interval, orbital phase, and recent accretion-state evolution — to forecast the next nova eruption of T Coronae Borealis; conditioning on no eruption through July 11, 2026, the study tightens the predicted window.

HOT JUPITERS FORMED COLD

• Atmospheric composition modeling of hot Jupiters suggests the majority formed beyond the water ice line in their protoplanetary disks and later migrated inward, with volatile species providing the chemical fingerprint of formation location.

H2 MOLECULES AS DWARF AGN DETECTORS

• Researchers propose H2 emission lines as a new diagnostic to identify active galactic nuclei in dwarf galaxies hosting intermediate-mass black holes, noting these objects are systematically misclassified as star-forming galaxies in standard optical diagnostics.

FAST RADIO BURSTS TEST COSMIC ISOTROPY

• Using 536 FRBs from the first CHIME/FRB catalog and two independent statistical methods (two-point angular correlation function and sigma-map), a new study finds no significant anisotropy in the Universe after correcting for CHIME's observational biases.

PRIMORDIAL BLACK HOLES AND DUST HEATING

• A refined study of primordial black hole dark matter constraints via Hawking-radiation dust heating finds that incorporating PBH spin and varying dark-matter halo profiles meaningfully shifts previous exclusion limits for PBH masses between 10^15 and 10^18 grams.

UPPER SCORPIUS DISK DUST BUDGET

• A survey of protoplanetary disks in the Upper Scorpius association (age approximately 5-12 Myr) measures total dust masses to benchmark how much raw material remains available for planet formation at an age comparable to key stages of planetary assembly.
