Sols 4534-4535: Last Call for the Layered Sulfates? (West of Texoli Butte, Headed West)
- Curiosity rover on Mars is exploring the transition between rougher-textured layered sulfates to smoother-appearing surface cross-cut with boxwork features.
- The rover focused on collecting observations of the previous unit of layered sulfates, using instruments like APXS, ChemCam LIBS, and MAHLI for geochemical measurements and high-resolution imaging.
- ChemCam targeted a scour feature on Texoli butte, indicating ancient wind events during the deposition of the layers.
- Future plans include imaging the sulfate/boxwork unit contact, covering honeycomb features in nearby blocks, and monitoring the modern Martian environment post-drive.

Doomed Soviet spacecraft Kosmos 482 could hit Earth tonight. Here's when.
- The failed Soviet spacecraft Kosmos 482 is expected to reenter Earth's atmosphere this weekend, possibly crashing as early as tonight.
- Predictions from the European Space Agency suggest a reentry time around 2:26 a.m. EDT on Saturday, with a window between 10 p.m. EDT Friday and 7 a.m. EDT Saturday.
- Kayhan Space predicts a narrower window for reentry at 2:28 a.m. ET on May 10, plus or minus 2.4 hours.
- The uncertain atmospheric density in lower altitudes poses challenges for precise predictions.
- The 1-meter-wide Kosmos 482 could land anywhere between 52 degrees north and 52 degrees south, with high likelihood of ocean landing.
- The prospect of the spacecraft hitting a person is minimal, typical of falling space debris scenarios.
- Kosmos 482 was part of the Soviet Venera mission to Venus in 1972 but got stuck in Earth's orbit due to a rocket malfunction.
- With over 1.2 million space debris pieces in orbit, reentries and collisions are increasing, emphasizing the need for responsible end-of-life plans for satellites.

Part of Soviet-era spacecraft to crash to Earth this weekend
- Part of a Soviet spacecraft, Kosmos 482, is expected to crash back down to Earth this weekend, uncertain of the landing location.
- Launched in 1972, the spacecraft was intended for Venus but failed to escape low Earth orbit and broke into four pieces.
- The robust design of the spacecraft, meant to withstand Venus's extreme conditions, is likely to survive re-entry into Earth's atmosphere.
- The landing probe could crash between latitudes of 52 degrees north and 52 degrees south, with expected re-entry from 9 to 10 May.

DNA-like molecule that could survive in Venus’s harsh clouds, study finds
- A new study has revealed that a DNA-like molecule called peptide nucleic acid (PNA) could survive in Venus's harsh clouds filled with sulfuric acid and other chemicals.
- PNA, a structural cousin of DNA, showed exceptional stability in conditions simulating Venus's clouds, suggesting the possibility of life or its building blocks in such extreme environments.
- Previous discoveries of phosphine gas and ammonia in Venus's atmosphere hinted at the potential for life, despite the planet's hostile conditions.
- Researchers aim to create a genetic polymer similar to DNA that can withstand Venus's varied cloud temperatures, potentially expanding our understanding of where life could exist in the universe.

NASA Study Reveals Venus Crust Surprise
- New NASA-funded research reveals surprising findings about the crust on Venus, Earth's hotter twin.
- Contrary to expectations, Venus' crust does not grow thicker over time but experiences a crust metamorphism process based on rock density and melting cycles.
- Venus has a one-piece crust with no plate tectonics like on Earth, making its 25-40 miles thick crust subject to metamorphism.
- The research suggests that Venus' crust undergoes processes like breaking off, melting, and driving volcanic activity, offering new insights into the geological evolution of the planet.

Hubble observes a rogue black hole devouring a star
- Astronomers using the Hubble Space Telescope have observed a black hole devouring a star, creating a tidal disruption event (TDE) named AT2024tvd.
- The black hole, located 2,600 light years away, was a wandering rogue unlike most supermassive black holes usually found in the center of galaxies.
- The researchers used Hubble, NASA’s Chandra X-Ray Observatory, and the NRAO Very Large Array telescope to observe the TDE and study the black hole's behavior.
- The galaxy where this event occurred contains two supermassive black holes, suggesting a previous merger of smaller galaxies, and theorizing a potential future merger of the two black holes.

Conclave: What’s in that black or white smoke?
- White smoke from the Sistine Chapel signifies the election of a new Pope during a papal conclave.
- The tradition of using smoke signals originated from burning ballot papers for secrecy in the 15th century.
- Black smoke indicates no consensus among cardinals, while white smoke confirms the selection of a new Pope.
- Initially, the smoke was not intended as public signaling, but observers interpreted it as such over time.
- Earlier methods involved burning damp straw and tar, leading to confusion between black and white smoke colors.
- The current formula for generating black smoke at the conclave includes potassium perchlorate and anthracene.
- White smoke is produced using potassium chlorate, lactose, and pine rosin for a cleaner combustion process.
- Modern chemistry has refined the smoke production to ensure clear distinctions between black and white smoke signals.
- The evolution of the smoke signaling system at the conclave highlights its transformation into a precise communication tool.
- The practice of generating white or black smoke has become a distinctive and unmistakable feature during papal elections.
