It will use Nuclear Electric Propulsion and carry the Skyfall payload — three Ingenuity-class helicopters designed to scout future human landing sites and map subsurface water ice. Source: https://www.space.com/astronomy/mars/nasas-1st-nuclear-powered-interplanetary-spacecraft-will-send-skyfall-helicopters-to-mars-in-2028 Story 3: Two Planets Forming Around Infant Star WISPIT 2 Astronomers using the ESO's Very Large Telescope have directly imaged two gas giant planets forming around the 5.4-million-year-old star WISPIT 2, located 437 light-years away in Aquila. The system is described as a mirror of our early solar system, with potential for more planets yet to be discovered. Published in The Astrophysical Journal Letters.

The technique could replace expensive individual seismometers, with a single cable acting as thousands of sensors across hundreds of kilometres of lunar terrain. Source: https://www.space.com/astronomy/moon/future-artemis-missions-could-use-fiber-optic-cables-to-monitor-moonquakes Story 6: Rocket Lab 'Daughter of the Stars' — Europe's First Celeste Navigation Satellites Rocket Lab's Electron rocket launched the first two satellites for ESA's Celeste LEO-PNT constellation from Māhia, New Zealand on March 25. The mission is ESA's first foray into low-Earth orbit navigation, designed to complement and strengthen Europe's Galileo system. The constellation is named after Maria Celeste, daughter of Galileo Galilei.

Thank you for listening to Astronomy Daily! Here's everything from today's episode:   Story 1: Artemis II — T-Minus Days to Launch NASA is targeting April 1, 2026 for the launch of Artemis II — the first crewed lunar flyby since Apollo 17 in 1972. The crew of Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will fly a 10-day free-return trajectory around the Moon aboard the Orion spacecraft on the SLS rocket from Kennedy Space Center. The six-day launch window runs April 1–6. Meanwhile, a new analysis suggests the mission could face elevated solar superflare risk, though NASA is proceeding after a successful Flight Readiness Review. Source: NASA — https://www.nasa.gov/mission/artemis-ii/ Solar risk analysis: https://www.space.com/space-exploration/artemis/artemis-2-moon-mission-shouldnt-launch-until-late-2026-new-analysis-of-solar-superflares-suggests   Story 2: G3 Geomagnetic Storm & Aurora Australis Multiple coronal mass ejections from the Sun triggered a G3 (strong) geomagnetic storm, producing vivid auroral displays from New York to Scotland to — remarkably — Melbourne, Sydney, Brisbane, and Adelaide. The Australian Bureau of Meteorology issued a severe storm warning for March 23. Conditions are easing on March 24 (Kp 3–4) but some aurora activity may continue. March is historically the best month for auroras due to the equinox effect, and with Solar Cycle 25 at its peak, scientists say this could be the best aurora viewing period until the mid-2030s. Aurora forecast: https://earthsky.org/sun/sun-news-activity-solar-flare-cme-aurora-updates/ Aurora Australis guide: https://www.elle.com.au/culture/news/aurora-australis-southern-lights-march-2026-tonight-alert/   Story 3: JWST Finds 'Impossible' Atmosphere on Lava World TOI-561 b A Carnegie Institution-led team used NASA's James Webb Space Telescope to detect the strongest evidence yet for an atmosphere around a rocky exoplanet. TOI-561 b — an ultra-hot super-Earth about twice Earth's mass, orbiting its star every 10.56 hours — was expected to be a bare rock. Instead, JWST measured a dayside temperature far cooler than a bare rock would produce, indicating a thick atmosphere redistributing heat above a global magma ocean. The findings were published in The Astrophysical Journal Letters.

A Brown University-led team found volcanic material from the Taurus-Littrow region is strongly depleted in sulfur-33 — unlike anything found on Earth. Possible explanations include ancient lunar atmospheric chemistry or a legacy of the Theia impact that formed the Moon. Published in the Journal of Geophysical Research: Planets.

The 73rd orbital launch attempt of 2026 worldwide. Full preview: https://www.nasaspaceflight.com/2026/03/launch-preview-032326/   Update: Progress MS-33 & Spectrum Rocket Progress MS-33 (also known as Progress 94) launched from the newly-repaired Site 31/6 at Baikonur on March 22 carrying 2,509 kg of supplies for the ISS Expedition 74 crew. A KURS antenna failure required ISS commander Sergei Kud-Sverchkov to dock the vehicle manually using the TORU backup system, scheduled for 13:34 UTC on March 24. Separately, Isar Aerospace's Spectrum rocket remains on the pad at Andøya, Norway, with a new launch window on March 25 (20:00–21:00 UTC) after weather delays.

Astronomy Daily — Season 5, Episode 70 Monday, March 23, 2026   In today's episode, Anna and Avery cover six stories spanning a live European rocket launch attempt, a sixty-year-old NASA emergency brought back to life through newly surfaced photographs, a cosmic explosion caught only by its echo, the fight to preserve the night sky, a supply run to the ISS with an unexpected complication, and a first-of-its-kind discovery involving brown dwarf stars.   
Story 1: Europe's Spectrum Rocket — Bid for Orbit Today Isar Aerospace's Spectrum rocket is attempting its second test flight today — its qualification mission for ESA's European Launcher Challenge. Launching from Andøya Spaceport in Norway, the mission carries five CubeSats and one experiment from European universities and companies, all supported by ESA's Boost! program. If successful, it would mark a landmark moment for European sovereign access to space. Source: ESA — Spectrum's Qualifying Second Launch Story 2: Neil Armstrong — The Gemini 8 Emergency Sixty years ago this month, Neil Armstrong and David Scott survived one of NASA's most dangerous pre-Apollo emergencies aboard Gemini 8. A spacecraft malfunction sent the capsule into an uncontrolled spin reaching one revolution per second. Never-before-seen photographs of Armstrong's recovery have been donated to the Armstrong Air and Space Museum in Wapakoneta, Ohio. Source: Phys.org — Space News Story 3: Astronomers Catch the Echo of a Billion-Sun Explosion Using the ASKAP radio telescope in Western Australia, astronomers identified ASKAP J005512-255834 — a radio signal representing the most convincing "orphan afterglow" of a gamma-ray burst ever detected. The original explosion went unseen because its jet wasn't aimed at Earth, but the lingering radio echo has been detectable for over 1,000 days. Research published in The Astrophysical Journal. Source: The Conversation — A Cosmic Explosion With the Force of a Billion Suns Story 4: The Fight to Save the Night Sky The Royal Astronomical Society, ESA, and the International Astronomical Union have filed formal objections to the FCC over two proposed satellite constellations: SpaceX's application for up to one million orbiting AI data centre satellites, and Reflect Orbital's proposal for 50,000 space mirrors each four times brighter than the full Moon. Experts warn the proposals could permanently transform humanity's view of the night sky. Source: Space.com — Astronomers Protest Giant Orbiting Mirror Project Story 5: Progress 94 Launches to ISS — With a Glitch Russia's Progress 94 cargo spacecraft launched successfully from Baikonur on March 22, carrying around three tonnes of food, fuel, and supplies to the ISS. One of its KURS automated docking antennas failed to deploy after launch. Docking at the Poisk module is scheduled for March 24. If the antenna issue isn't resolved, commander Sergei Kud-Sverchkov will conduct a manual docking. Source: NASA — Progress Cargo Craft Launches to Resupply Station Crew Story 6: First-Ever Brown Dwarf Pair Caught in Mass Transfer Caltech researchers using the Zwicky Transient Facility have discovered ZTF J1239+8347 — the first-ever observed brown dwarf binary undergoing mass transfer. The pair orbit each other every 57 minutes at a separation smaller than the Earth-Moon distance. The system will eventually either merge into a single star or one dwarf will accrete enough mass to ignite fusion. Research published in The Astrophysical Journal Letters.

Today on Astronomy Daily: NASA's Artemis II moon rocket has arrived at Launch Pad 39B at Kennedy Space Center, with a launch target of April 1st — the first crewed mission beyond Earth orbit in over 53 years. Plus: astronomers have discovered the first-ever mass-transferring brown dwarf binary; Hubble accidentally caught a comet disintegrating in real time; 15 new moons have been confirmed around Jupiter and Saturn; our Moon is accumulating over 100 metric tons of human-made debris; and a dramatic spacecraft double-header — ESA's Proba-3 has been recovered from a month-long blackout, while NASA's MAVEN Mars orbiter remains missing after more than three months of silence.   Story 1: Artemis II Arrives at Launch Pad 39B NASA's Artemis II SLS rocket and Orion spacecraft completed an 11-hour overnight journey to Launch Pad 39B on March 20, 2026. Launch is targeted for no earlier than April 1. The crew — Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen — will fly a 10-day free-return trajectory around the Moon, making this the first crewed deep-space mission since Apollo 17 in December 1972. Source: https://www.nasa.gov/blogs/missions/2026/03/20/nasas-artemis-ii-rocket-arrives-at-launch-pad-39b/   Story 2: First Mass-Transferring Brown Dwarf Binary Researchers at Caltech have identified ZTF J1239+8347, a brown dwarf binary system with an orbital period of just 57.41 minutes in which one brown dwarf is actively pulling material from its companion — a first for this class of objects. The system, only ~1,000 light-years away, is a prime candidate for JWST follow-up observations. Published in The Astrophysical Journal Letters. Source: https://www.universetoday.com/articles/this-pair-of-brown-dwarfs-cant-get-enough-of-each-other   Story 3: Hubble Catches Comet C/2025 K1 Breaking Apart In a remarkable stroke of luck, NASA's Hubble Space Telescope captured comet C/2025 K1 (ATLAS) fragmenting into at least four pieces over three consecutive days in November 2025. The comet was not the original target of the observation. The findings, published in Icarus, reveal the comet is unusually carbon-depleted and raise new questions about the delay between fragmentation and visible brightening. Source: https://science.nasa.gov/missions/hubble/nasas-hubble-unexpectedly-catches-comet-breaking-up/   Story 4: 15 New Moons Confirmed for Jupiter and Saturn The Minor Planet Center announced on March 16, 2026 that four new moons have been confirmed around Jupiter (bringing its total to 101) and 11 new moons around Saturn (bringing its total to 285). All are small irregular moons, discovered by combining archival telescope data with new observations. With the Vera C. Rubin Observatory now operational, further discoveries are expected. Source: https://earthsky.org/space/more-moons-for-jupiter-and-saturn-total-satellite-discoveries/   Story 5: Human Debris on the Moon — Over 100 Metric Tons and Counting More than 100 metric tons of human-made objects now litter the lunar surface — spacecraft hardware, scientific instruments, and even waste from Apollo missions. With a wave of crewed and commercial lunar missions approaching under Artemis and beyond, space policy researchers are urging the development of international agreements to protect scientifically sensitive lunar sites before they are damaged or contaminated by human activity. Source: https://www.universetoday.com — lunar debris policy   Story 6: MAVEN Still Missing / Proba-3 Recovered NASA's MAVEN Mars orbiter, lost since December 6, 2025, remains uncontacted despite three months of recovery efforts using the Deep Space Network, Green Bank Observatory, and the Curiosity rover. An anomaly review board is assessing options. Meanwhile, ESA's Proba-3 coronagraph spacecraft — silent since February 14 after a power failure — has been successfully recovered after engineers exploited a brief window when the tumbling spacecraft's solar panels briefly faced the Sun.

It's the first day of astronomical spring — and the universe is celebrating in style. On today's Astronomy Daily, Anna and Avery cover a triple CME solar storm with aurora potential reaching as far south as Illinois, explain why the vernal equinox amplifies aurora activity, report on the ongoing meteorite hunt following Tuesday's spectacular Ohio fireball, reveal an extraordinary 14-billion-year-old star that carries the chemical fingerprints of the universe's very first stars, bring a happy update on Europe's Proba-3 solar science satellite which has ended a month of silence, and explain how X-ray CT scans of returned asteroid samples finally cracked one of Bennu's longest-standing mysteries.   Stories in This Episode 1. Triple CME Strike + Equinox Aurora Alert Three coronal mass ejections (CMEs) are currently en route to Earth, with the first arriving today. Forecasters predict G2 (moderate) to G3 (strong) geomagnetic storm conditions, potentially bringing auroras as far south as Illinois. The timing coincides with the vernal equinox — historically one of the best aurora windows of the year due to the Russell-McPherron effect. 2. The Vernal Equinox — Today! The 2026 March equinox arrived today at 14:46 UTC, marking the astronomical start of spring in the Northern Hemisphere (and autumn in the Southern). Tonight, a thin crescent Moon appears alongside Venus in the west-southwest sky. 3. Ohio Fireball — Meteorite Hunt Underway On St. Patrick's Day (March 17), a seven-ton asteroid exploded over northeast Ohio with the force of 250 tons of TNT. NASA confirmed meteorites landed near Medina County, and hunters from across the US have already found fragments in the Sharon Center area. 4. Ancient 'Cosmic Fossil' Star PicII-503 Astronomers have discovered PicII-503, a second-generation star in the Pictor II dwarf galaxy with only 1/40,000th of the Sun's iron — the lowest ever measured outside the Milky Way. Its extraordinary carbon-to-iron ratio links it to mysterious carbon-enhanced metal-poor stars scattered across our galaxy's halo, solving a long-standing stellar mystery. Published in Nature Astronomy by Anirudh Chiti (Stanford) et al. 5. Proba-3 Phones Home — 'A Great Relief!' ESA confirmed on March 19 that its Proba-3 Coronagraph satellite — silent since mid-February after an anomaly caused it to lose attitude control — has reestablished contact via the Villafranca ground station. The spacecraft is in safe mode, solar-powered, and undergoing health checks before science operations can resume. 6. NASA Cracks Bennu's Boulder Mystery X-ray CT scans of returned OSIRIS-REx samples reveal Bennu's boulders are riddled with internal crack networks — the missing piece explaining the asteroid's puzzling low thermal inertia. Published in Nature Communications. The findings will improve asteroid characterisation from Earth-based telescopes globally.   Source Links Triple CME / Aurora Alert — Space.com: https://www.space.com/stargazing/auroras/aurora-alert-powerful-geomagnetic-storm-could-spark-northern-lights-as-far-south-as-illinois-on-march-19 Triple CME / Sun News — EarthSky: https://earthsky.org/sun/sun-news-activity-solar-flare-cme-aurora-updates/ NOAA Space Weather Prediction Centre: https://www.spaceweather.gov Vernal Equinox 2026 — EarthSky: https://earthsky.org/astronomy-essentials/everything-you-need-to-know-vernal-or-spring-equinox/ Ohio Fireball — EarthSky: https://earthsky.org/earth/sonic-boom-from-a-meteor-cleveland-ohio-and-pennsylvania-mar-17-2026/ Ohio Meteorite Hunt — Cleveland19: https://www.cleveland19.com/2026/03/19/meteorite-hunters-states-away-find-fragments-northeast-ohio/ PicII-503 Discovery — NOIRLab: https://noirlab.edu/public/news/noirlab2607/ PicII-503 — Nature Astronomy (DOI): https://doi.org/10.1038/s41550-026-02802-z Proba-3 Phones Home — Space.com: https://www.space.com/space-exploration/missions/a-great-relief-europes-proba-3-solar-eclipse-satellite-phones-home-after-a-month-of-silence Proba-3 ESA Statement: https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Proba-3_s_Coronagraph_is_alive Bennu Mystery Solved — NASA Science: https://science.nasa.gov/missions/osiris-rex/asteroid-bennus-rugged-surface-baffled-nasa-we-finally-know-why/ Bennu — Nature Communications (SciTechDaily): https://scitechdaily.com/we-were-scratching-our-heads-scientists-finally-solve-asteroid-bennus-surface-mystery/   Find us: astronomydaily.io  |  @AstroDailyPod on Twitter/X, Instagram, TikTok, YouTube & Tumblr Part of the Bitesz.com Podcast Network

A massive day in space as NASA's Artemis II moon rocket heads to the launchpad tonight, NASA and China both conduct spacewalks, CERN announces a brand-new particle, and astronomers reveal a nearby galaxy has been hiding the aftermath of a cosmic collision.   Episode Highlights   🚀 Story 1: Artemis II Rollout — The Moon Rocket Heads to the Pad Tonight NASA is rolling the Artemis II Space Launch System and Orion spacecraft to Launch Pad 39B tonight (March 19), targeting an 8 p.m. EDT start for the slow 4-mile crawler journey. The April 1 launch window remains firmly on track. Crew members Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen have entered quarantine — making history as the first crew to venture to the vicinity of the Moon since 1972. Source: NASA Blogs / Space.com   👨‍🚀 Story 2: Dual Spacewalk Day — ISS & Tiangong Both Suit Up NASA astronauts Jessica Meir and Chris Williams completed U.S. Spacewalk 94 on March 18, spending 7 hours and 2 minutes preparing the ISS for a new roll-out solar array. Meanwhile on March 16, Shenzhou 21 commander Zhang Lu tied the Chinese EVA record with his sixth career spacewalk alongside crewmate Wu Fei outside China's Tiangong station. Sources: NASA / Space.com   ⚛️ Story 3: CERN's LHCb Discovers New Doubly Charmed Particle The LHCb experiment at CERN announced the first discovery made by its upgraded detector: the Xi-cc-plus baryon, a proton-like particle containing two charm quarks and one down quark, making it roughly four times heavier than a proton. Detected at 7-sigma significance, it settles a two-decade-old scientific dispute and is the 80th particle discovered by LHCb. Source: CERN / Universe Today   🌌 Story 4: Small Magellanic Cloud Caught Mid-Transformation University of Arizona astronomers have confirmed that the Small Magellanic Cloud — one of the Milky Way's closest galactic neighbours — collided directly with the Large Magellanic Cloud a few hundred million years ago and is still reeling from the impact. The finding upends decades of assumptions about the SMC's use as a benchmark for early universe galaxy studies. Source: The Astrophysical Journal / Sky & Telescope   🪐 Story 5: Exotrojans — Hunting Asteroid Companions Around Other Stars A new paper in The Astrophysical Journal by Jackson Taylor (West Virginia University) and colleagues pushes the search for exotrojans — asteroid co-orbital companions to exoplanets — into some of the most extreme environments yet studied, as the hunt continues for the first confirmed detection. Source: The Astrophysical Journal / Universe Today   📡 Story 6: SETI Rethink — Time to Broaden the Search A new paper argues that the decades-long focus on narrow radio and microwave bandwidths in the search for alien signals may be too limiting, and proposes broadening the electromagnetic search to a much wider range of the spectrum.

In today's episode of Astronomy Daily, Anna and Avery cover six remarkable stories spanning an interstellar farewell, a stunning pre-dawn sky show, a potential new Martian mineral, ghost particles from long-dead stars, a revolutionary new framework for detecting alien life, and the astonishing possibility of habitable moons drifting starless through the galaxy.   Stories Covered in S05E64 1. 3I/ATLAS: The Interstellar Comet's Jupiter Farewell: Today marks the closest approach of interstellar comet 3I/ATLAS to Jupiter before it leaves our solar system forever. New ALMA data reveals the comet carries extraordinary levels of methanol — a chemical fingerprint from another solar system entirely.   2. Mercury, Mars & the Moon: Tonight and tomorrow morning, Mercury and Mars gather close to a crescent Moon in the pre-dawn sky. Southern Hemisphere observers have the best view. This week also brings the March equinox (March 20) and heightened aurora activity.   3. A New Mineral on Mars?: Scientists may have discovered a previously unknown mineral hidden in Mars's ancient sulfate deposits. Found by combining laboratory experiments with orbital spectroscopy, the potential discovery could shed new light on Mars's ancient watery past.   4. Ghost Particles from Dead Stars: Japan's upgraded Super-Kamiokande detector may detect the Diffuse Supernova Neutrino Background for the first time in 2026 — a faint signal from every supernova across cosmic history, including stars that exploded before Earth was born.   5. Life, But Not As We Know It: A new framework called Assembly Theory, published today in Universe Today, offers a way to detect alien life that bears no resemblance to life on Earth. Rather than searching for specific biosignature gases, it asks how complex the atmospheric chemistry is — and is designed for the upcoming Habitable Worlds Observatory.   6. Starless Moons: Moons orbiting free-floating planets — worlds ejected from their home solar systems — could sustain liquid water oceans for up to 4.3 billion years, powered by tidal heating and insulated by hydrogen atmospheres. No star required.   Astronomy Daily is part of the Bitesz.com Podcast Network. New episodes every weekday.

Episode: S05E63  |  Date: Saturday, 14 March 2026 Hosted by Anna & Avery  |  Astronomy Daily Podcast Network — Bitesz.com   From galactic migrations to Pi Day planets, Episode 63 covers six stories that span the breadth of the solar system and beyond. Our Sun turns out to have hitched a ride outward from the Milky Way's interior billions of years ago — and brought thousands of stellar companions with it. China has named a leading candidate for its first crewed Moon landing. Russia is dusting off the legacy of the legendary Soviet Venera programme with an ambitious 2036 return to Venus. NASA's nuclear-powered Titan drone is now being physically built. China's Mars sample return mission is constructing actual spacecraft. And in honour of Pi Day, we visit the exoplanet whose year lasts almost exactly 3.14 days.   Story 1: The Sun Was Part of a Galactic Migration of Solar Twins A new study in Astronomy & Astrophysics by researchers at Tokyo Metropolitan University and the National Astronomical Observatory of Japan has built the largest-ever catalogue of solar twins — 6,594 Sun-like stars. Using ESA's Gaia satellite, they found a clustering of stars aged 4–6 billion years, suggesting the Sun migrated outward from the Milky Way's inner regions billions of years ago, possibly when the galactic bar was still forming and its 'corotation barrier' was weak enough to allow mass stellar movement. This migration may have placed Earth in a calmer, more life-friendly region of the Galaxy.   •      Journal: Astronomy & Astrophysics (March 2026) •      Lead researchers: Daisuke Taniguchi (Tokyo Metropolitan University) & Takuji Tsujimoto (NAOJ) •      Data source: ESA Gaia satellite — catalogue of ~2 billion stars •      Key finding: Sun likely formed ~10,000 light-years closer to the Galactic Centre than its current position   Story 2: China Eyes Rimae Bode for Its First Crewed Moon Landing A study published in Nature Astronomy (9 March 2026) proposes Rimae Bode — a volcanic region near Sinus Aestuum on the lunar near side — as a prime candidate for China's first crewed lunar landing, targeted for 2030. The site contains five distinct terrain types including pyroclastic deposits, mare basalts, rille systems and highland material. Researcher Jun Huang (China University of Geosciences, Wuhan) described it as a 'geological museum.' Four specific landing spots within the region have been proposed.   •      Journal: Nature Astronomy (March 2026) •      Lead researcher: Jun Huang, China University of Geosciences, Wuhan •      Site: Rimae Bode, near Sinus Aestuum, lunar near side •      Oldest volcanic activity in region: ~3.2–3.7 billion years ago •      China's crewed lunar landing target: 2030   Story 3: Russia Plans Venera-D Mission to Venus in 2036 Russia's First Deputy Prime Minister Denis Manturov confirmed on 10 March 2026 that Russia plans to launch the Venera-D mission — comprising a lander, atmospheric balloon, and orbiter — to Venus in 2036. The mission would extend the legacy of the Soviet Venera programme (1961–1983), which remains the only national programme to have successfully landed on Venus. Scientific goals include searching for microbial life in Venus's clouds and studying the planet's atmosphere.   •      Mission: Venera-D (lander + balloon + orbiter) •      Planned launch: 2036 •      Agency: Roscosmos •      Heritage: Soviet Venera programme — 16 missions, 1961–1983 •      Science goal: Search for biosignatures in Venusian cloud layers (48–60 km altitude) •      Source: TASS, citing Razvedchik Journal interview with Denis Manturov   Story 4: NASA Begins Building Dragonfly — Nuclear-Powered Drone for Titan NASA and Johns Hopkins Applied Physics Laboratory (APL) officially began integration and testing of the Dragonfly rotorcraft on 10 March 2026. The car-sized, nuclear-powered octocopter is designed to fly across the surface of Saturn's moon Titan, targeting a 2028 launch on a SpaceX Falcon Heavy and arriving at Titan in 2034. It will explore diverse terrain including organic dunes and the Selk impact crater, studying prebiotic chemistry relevant to the origins of life.   •      Mission: Dragonfly | Agency: NASA / Johns Hopkins APL •      Launch: No earlier than summer 2028 (SpaceX Falcon Heavy) •      Arrival: Titan, 2034 | Mission duration: ~3.3 years •      Power: Radioisotope thermoelectric generator (nuclear) •      Range: >108 miles (175 km) across Titan's surface •      Quote: "This milestone essentially marks the birth of our flight system." — Elizabeth Turtle, PI   Story 5: China's Tianwen-3 Mars Sample Return Enters Construction Phase China's Tianwen-3 mission chief designer Liu Jizhong announced on 12 March 2026 that the mission has achieved key technology breakthroughs and is entering flight model development — building the actual spacecraft. Two Long March 5 rockets will launch in late 2028, carrying a lander/ascent vehicle and an orbiter/return spacecraft respectively. The goal is to return at least 500 grams of Martian samples to Earth by 2031 — what would be humanity's first Mars sample return.   •      Mission: Tianwen-3 | Agency: CNSA •      Launch: Late 2028 (two Long March 5 rockets) •      Sample return: Earth, targeted 2031 •      Sample target: Minimum 500 grams of Martian rock and soil •      Landing site candidates: 19 remaining (narrowing to 3 by end of 2026) •      Primary science goal: Search for biosignatures / signs of past life on Mars •      Note: NASA's Mars Sample Return was effectively cancelled in early 2026   Story 6 (Pi Day Special): K2-315b — The Exoplanet with a 3.14-Day Year In honour of Pi Day (3/14), NASA's Astronomy Picture of the Day features K2-315b — an Earth-sized exoplanet orbiting a cool red dwarf star approximately 185 light-years away. Its orbital period of almost exactly 3.14159 days makes it one of the most mathematically charming exoplanet discoveries on record. Discovered using Kepler K2 mission data and announced in 2020, the planet orbits so close to its star that its surface is extremely hot and definitely uninhabitable — but delightfully pi-shaped in its year length.   •      Exoplanet: K2-315b •      Distance: ~185 light-years •      Host star: Cool red dwarf (M-type) •      Orbital period: 3.14159 days •      Discovery: Kepler K2 mission data, announced 2020 •      Surface: Extremely hot — far too close to its star for habitability •      Today's NASA APOD (14 March 2026): astronomydaily.io for link
