      Perseverance Finds Popcorn on Planet Mars
      Mars Perseverance Sol 1175 – Right Mastcam-Z Camera: A jumbled field of light toned rocks with unusual ‘popcorn’-like textures and abundant mineral veins. NASA’s Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was acquired on June 10, 2024 (Sol 1175) at the local mean solar time of 14:04:57. NASA/JPL-Caltech/ASU After months of driving, Perseverance has finally arrived at ‘Bright Angel’, discovering oddly textured rock unlike any the rover has seen before. The team now plans to drive up the slope to uncover the origin of this rock sequence and its relationship to the margin unit.
      Having completed a survey of the intriguing and diverse boulders at ‘Mount Washburn,’ the rover headed north, parking just in front of an exposure of layered light toned rock. This provided the team with our first close-up look of the rocks that make up the ‘Bright Angel’ exposure, so Perseverance stopped to acquire images, before driving west to a larger and more accessible outcrop where the rover will conduct detailed exploration.
      Perseverance arrived at the base of this outcrop on sol 1175, and geologists on the science team were mesmerized by the strange textures of the light toned rocks found there. These rocks are filled with sharp ridges that resemble the mineral veins found at the base of the fan, but there appears to be more of them here. Additionally, some rocks are densely packed with small spheres, and we’ve jokingly referred to this as a ‘popcorn’-like texture. Together, these features suggest that groundwater flowed through these rocks after they were laid down. Next, Perseverance will gradually ascend up the rock exposure, taking measurements as it goes. Over the weekend, the abrasion tool will be used to take a close-up look and acquire detailed chemical information using the instruments on the rover’s arm. With this data in hand, the team will decide whether or not to sample. Once our exploration at ‘Bright Angel’ is complete, we will drive south back across Neretva Vallis and explore a site called ‘Serpentine Rapids’.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Credit: NASA/Ryan Fitzgibbons What do you give to an ocean that has everything? This year, for National Ocean Month, NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite— is gifting us a unique look at our home planet. The visualizations created with data from the satellite, which launched on Feb. 8, are already enhancing the ways that we view our seas and skies. 
      The PACE satellite views our entire planet every day, returning data at a cadence that allows scientists to track and monitor the rapidly changing atmosphere and ocean, including cloud formation, aerosol movement, and differences in microscopic ocean life over time.
      The visualization starts with a view of swaths of Earth from PACE’s Ocean Color Instrument. The Ocean Color Instrument observes Earth in ultraviolet, visible, and near infrared light — over 200 wavelengths. With this level of detail, scientists can now, from space, regularly identify specific communities of phytoplankton — tiny organisms floating near the surface of the ocean that serve as the center of the marine food web. This is a major advance, as different types of phytoplankton play different roles in ocean ecosystems and health.
      PACE orbits Earth in this visualization, exposing a swath of true color imagery. NASA’s Scientific Visualization Studio Zooming in, the visualization shows the ecosystems and surrounding atmosphere off the United States’ East Coast and The Bahamas on March 21. Like previous satellites, the Ocean Color Instrument can detect chlorophyll in the ocean, which indicates the presence and abundance of phytoplankton. The Ocean Color Instrument adds to this by allowing scientists to determine the types of phytoplankton present, such as the three different types of phytoplankton identified in the visualization.

In light blue are prochlorococcus, the smallest known organism to turn sunlight into energy (photosynthesis); they account for a major fraction of all photosynthesis that occurs in the ocean. The portion of the bloom in bright pink indicates synechococcus, a phytoplankton group that can color the water light pink when many are present in a small area.

      The PACE satellite’s two polarimeters, Hyper-Angular Rainbow Polarimeter #2 (HARP2) and Spectro-polarimeter for Planetary Exploration one (SPEXone), provide a unique view of Earth’s atmosphere, helping scientists learn more about clouds and small particles called aerosols. The polarimeters measure light that reflects off of these particles. By learning more about the interactions between clouds and aerosols, these data will ultimately help make climate models more accurate. Additionally, aerosols can degrade air quality, so monitoring their properties and movement is important for human health.

These data — a measure of the light scattering and absorbing properties of aerosols — help scientists not only locate the aerosols, but identify the type. Near the coast, the aerosols are most likely smoke from fires in the U.S. southeast. Adding detail to the visualization and the science, the thin swath of SPEXone data furthers the information by showing the aerosol particle size.
      Over the next year, PACE scientists aim to create the first global maps of phytoplankton communities and glean new insights into how fisheries and aquatic resources are responding to Earth’s changing climate.

      NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) spacecraft was specifically designed to study the invisible universe of Earth’s sea and sky from the vantage point of space. We’ve measured 4-6 colors of the rainbow for decades, which has enabled us to “see” phytoplankton from space through the lens of its primary photosynthetic pigment, chlorophyll-a. PACE’s primary instrument is the first of its kind to measure all the colors of the rainbow, every day, everywhere. That means we can identify the type of phytoplankton behind the chlorophyll-a. Different types of phytoplankton have different effects on the food web, on water management, and on the climate, via their impact on the carbon cycle.NASA's Scientific Visualization Studio By Erica McNamee

      Artist’s concept of a previously proposed possible planet, HD 26965 b – often compared to the fictional “Vulcan” in the Star Trek universe. Credit: JPL-Caltech The discovery
      A planet thought to orbit the star 40 Eridani A – host to Mr. Spock’s fictional home planet, Vulcan, in the “Star Trek” universe – is really a kind of astronomical illusion caused by the pulses and jitters of the star itself, a new study shows.
      Key facts
      The possible detection of a planet orbiting a star that Star Trek made famous drew excitement and plenty of attention when it was announced in 2018. Only five years later, the planet appeared to be on shaky ground when other researchers questioned whether it was there at all. Now, precision measurements using a NASA-NSF instrument, installed a few years ago atop Kitt Peak in Arizona, seem to have returned the planet Vulcan even more definitively to the realm of science fiction.
      Two methods for detecting exoplanets – planets orbiting other stars – dominate all others in the continuing search for strange new worlds. The transit method, watching for the tiny dip in starlight as a planet crosses the face of its star, is responsible for the vast majority of detections. But the “radial velocity” method also has racked up a healthy share of exoplanet discoveries. This method is especially important for systems with planets that don’t, from Earth’s point of view, cross the faces of their stars. By tracking subtle shifts in starlight, scientists can measure “wobbles” in the star itself, as the gravity of an orbiting planet tugs it one way, then another. For very large planets, the radial velocity signal mostly leads to unambiguous planet detections. But not-so-large planets can be problematic.
      Even the scientists who made the original, possible detection of planet HD 26965 b – almost immediately compared to the fictional Vulcan – cautioned that it could turn out to be messy stellar jitters masquerading as a planet. They reported evidence of a “super-Earth” – larger than Earth, smaller than Neptune – in a 42-day orbit around a Sun-like star about 16 light-years away. The new analysis, using high-precision radial velocity measurements not yet available in 2018, confirms that caution about the possible discovery was justified.
      The bad news for Star Trek fans comes from an instrument known as NEID, a recent addition to the complex of telescopes at Kitt Peak National Observatory. NEID, like other radial velocity instruments, relies on the “Doppler” effect: shifts in the light spectrum of a star that reveal its wobbling motions. In this case, parsing out the supposed planet signal at various wavelengths of light, emitted from different levels of the star’s outer shell, or photosphere, revealed significant differences between individual wavelength measurements – their Doppler shifts – and the total signal when they were all combined. That means, in all likelihood, the planet signal is really the flickering of something on the star’s surface that coincides with a 42-day rotation – perhaps the roiling of hotter and cooler layers beneath the star’s surface, called convection, combined with stellar surface features such as spots and “plages,” which are bright, active regions. Both can alter a star’s radial velocity signals.
      While the new finding, at least for now, robs star 40 Eridani A of its possible planet Vulcan, the news isn’t all bad. The demonstration of such finely tuned radial velocity measurements holds out the promise of making sharper observational distinctions between actual planets and the shakes and rattles on surfaces of distant stars.
      Fun facts
      Even the destruction of Vulcan has been anticipated in the Star Trek universe. Vulcan was first identified as Spock’s home planet in the original 1960s television series. But in the 2009 film, “Star Trek,” a Romulan villain named Nero employs an artificial black hole to blow Spock’s home world out of existence.
      The discoverers
      A science team led by astronomer Abigail Burrows of Dartmouth College, and previously of NASA’s Jet Propulsion Laboratory, published a paper describing the new result, “The death of Vulcan: NEID reveals the planet candidate orbiting HD 26965 is stellar activity,” in The Astronomical Journal in May 2024 (Note: HD 26965 is an alternate designation for the star, 40 Eridani A.)

      Much has been discussed about the strange objects discovered on Mars. Often dismissed as merely oddly shaped rocks or mere pareidolia, there is substantial evidence suggesting that Mars was once inhabited by intelligent life as well as a variety of animal and insect species. This raises the intriguing question of whether life still exists on the planet today. 
      Upon examining the objects captured in the following images by the Perseverance rover, one may wonder whether these are simply rocks, tricks of perception, or indications that the planet was indeed once inhabited, or perhaps still hosts humanoid figures and various animal species. 
      Image above: A petrified human-like figure concealed beneath a rock. It seems as if it wanted to protect itself from a horrific event. 
      Image above: Close-up images of the figure still reveal visible features such as an open mouth and eyes. 
      Image above: A curious object: It appears as though a possible creature has been ejected from a craft and remains seated in an ejection-like position. What's even stranger is that this creature apparently holding three bottles in its hands for some reason. 
      Image above: This image depicts what appears to be two peculiar animals. Figure 1 resembles a large ant, while Figure 2 resembles a cat-like creature. 
      Image above: Enlarged images of the ant and cat reveal more details. 
      Image above: A humanoid figure standing in front of a rock, cleverly camouflaged with clothes and hoodie matching the color of the rock.
      Image above: Yet the humanoid appears to have an apron wrapped around its body, as well as its legs and arms are clearly visible, showing off its humanoid form. 
      Image above: Additionally, the figure appears to be holding a creature that resembles an animal, see also the hindlegs of the animal. Adding to the intrigue is that there is another humanoid figure sitting nearby.
