  • NASA’s Perseverance Captures Deimos Before Dawn in Striking Martian Sky Image

    NASA’s Perseverance rover has delivered a striking early morning image of Mars’ moon Deimos, taken just before dawn on March 1, 2025 — Sol 1433 of the mission. Captured at 4:27 a.m. local time using the rover’s left navigation camera, the view combines 16 long-exposure shots taken over 52 seconds. Each frame used the maximum exposure setting of 3.28 seconds, enabling the camera to glimpse faint celestial features in Mars’ dim pre-dawn sky. Though the image appears hazy due to low light and digital noise, the effort reveals a rare visual of Deimos suspended in the Martian atmosphere.

    Perseverance’s Celestial Snapshot Reveals Deimos, Distant Stars, and Martian Sky Dynamics

    As per a report from NASA’s Jet Propulsion Laboratory, the brightness of Deimos is accompanied by multiple white specks across the sky, many of which are likely caused by image noise. Some of them could be cosmic rays hitting the sensor while exposing. Two bright spots, Regulus and Algieba, are easily found in the image. It adds perspective on the rover’s unique view of things, these stars, which belong to the Leo constellation. The image was stitched together onboard and transmitted later to Earth, where researchers analysed the result.

    These make the resultant composition an example of other possible roles of the Perseverance rover as an observational instrument apart from geology and surface exploration. While atmospheric haze and digital distortion make it difficult to show in full clarity, the long-exposure effort shows the faintness with which Martian moons and nearby stars can, in fact, still be tracked under controlled conditions. Deimos appears brighter due to its reflective nature and proximity during this early-morning observation.

    Researchers believe this type of celestial photography may enhance understanding of Mars‘ sky conditions and moon dynamics. Deimos and Phobos, the Red Planet’s two moons, are of growing interest as potential markers for future orbit-based missions. Capturing them from the surface during optimal lighting conditions offers new insights into their behaviour.

    NASA continues to push imaging capabilities on Mars through Perseverance’s tools. With each sol, even distant cosmic views — like Deimos before dawn — offer new visual science from the Martian frontier.

  • NASA’s SWOT Satellite Reveals Big Impact of Small Ocean Currents and Waves in n Marine Ecosystems

    Small-scale ocean features once overlooked are now seen as powerful forces shaping Earth’s climate and marine life. Developed in association with the French space agency CNES, the SWOT (Surface Water and Ocean Topography) satellite caught two-dimensional images of submesoscale waves and eddies about a mile across in a recent NASA-led study. Now clearly seen in before-unheard-of clarity, these currents are essential in moving carbon, nutrients, and heat across the ocean. The high-resolution data of the satellite provides the most comprehensive picture yet of how small-scale vertical currents affect the ecosystems and climatic systems of the world.

    NASA SWOT Satellite Discovers Vertical Ocean Currents Driving Climate and Ecosystem Change

    As per a recent report from NASA’s Jet Propulsion Laboratory, SWOT revealed how vertical ocean circulation, previously too fine for satellite observation but too broad for ship-based tools, drives exchanges between ocean depths and the atmosphere.

    “Vertical currents can bring heat from deep layers to the surface, warming the atmosphere,” notes oceanographer Matthew Archer in a statement. SWOT tracked a submesoscale eddy in the Pacific’s Kuroshio Current and measured vertical circulation of up to 14 metres per day, showing how such features help sustain surface ecosystems.

    The satellite also observed an internal solitary wave in the Andaman Sea with twice the energy of a typical internal tide, underscoring its ability to estimate energy movement in global waters. Scientists use sea surface height data from SWOT to infer wave slope and fluid pressure, which reveals current speed and the volume of energy or material being transported. “Force is the fundamental quantity driving fluid motion,” explained coauthor Jinbo Wang of Texas A&M University in the blog.

    Researchers emphasise SWOT’s role in reshaping ocean modelling. “Now models must adapt to these small-scale features,” denotes JPL’s Lee Fu in the official NASA blog, adding that SWOT data is already being integrated into NASA’s ECCO ocean model. Through continuous monitoring, SWOT is intended to help clarify among environmental changes, ocean-atmosphere interaction, and climate behaviour.

  • Japan Committed To Moon Missions As Trump Cuts NASA Budget: JAXA Chief

    Japan signed an agreement with NASA last year to include two Japanese astronauts and a Toyota-made rover in future missions to the lunar surface

    Japan is ready to support the United States’ lower-cost lunar missions, its space agency chief said on Friday, after the U.S. administration proposed a $6 billion cut to NASA’s budget that could upend the Artemis programme to return people to the moon.

    U.S.-led Artemis, established during President Donald Trump’s first term and joined by partners including Japan, the European Space Agency (ESA) and Canada, has grown into a multibillion-dollar project aiming to return astronauts to the moon for the first time since 1972.

    “If the U.S. were considering a better alternative in terms of budget or economics, we must respond to it,” Hiroshi Yamakawa, President of Japan Aerospace Exploration Agency (JAXA), told a monthly briefing.

    Trump unveiled his 2026 budget proposal for NASA earlier this month. It would almost halve the agency’s space science budget and reshape its exploration programmes to focus on Mars with “cost-effective” rockets and spaceships.

  • NASA’s James Webb Telescope Spots Frozen Water In Distant Star System For The First Time

    Crystalline water ice has been found in a dusty debris disk that orbits a Sun-like star, only 23 million years old, 155 light-years away.

    Astronomers confirmed water ice in a young star system using JWST.

    Crystalline water ice was found in the debris disk of star HD 181327.

    The star is 23 million years old and located 155 light-years away.

    Using NASA’s James Webb Space Telescope (JWST), a team of astronomers has confirmed the presence of frozen water in a distant but young star system. While scientists have found plenty of water ice in our solar system, it is the first time that they have definitive proof of frozen water in other star systems.

    The details, published in the journal Nature, state that crystalline water ice has been found in a dusty debris disk that orbits a Sun-like star, only 23 million years old, 155 light-years away. The star is slightly more massive and hotter than the Sun, which led to the formation of a slightly larger system around it.

    Webb’s findings showed there is a significant gap between the star, named HD 181327, and its debris disk, which is similar to our solar system’s Kuiper Belt.

    “Webb unambiguously detected not just water ice, but crystalline water ice, which is also found in locations like Saturn’s rings and icy bodies in our solar system’s Kuiper Belt,” said Chen Xie, the lead author of the new paper.

    “HD 181327 is a very active system. There are regular, ongoing collisions in its debris disk. When those icy bodies collide, they release tiny particles of dusty water ice that are perfectly sized for Webb to detect.”
