New research based on data from NASA’s InSight mission has uncovered a vast underground reservoir on Mars, capable of filling oceans on the planet’s surface. The study, published in Proceedings of the National Academy of Sciences, reveals that water, trapped in small cracks and pores within Mars’ crust, could cover the planet to a depth of 1 mile (1.6 kilometres).

The InSight mission operated from 2018 to 2022 and used a seismometer to probe Mars’ interior. This data indicates the reservoir lies between 7 and 12 miles (11.5 and 20 kilometres) beneath the Martian surface. Such a discovery provides a deeper understanding of Mars’ geological history and opens up new possibilities for exploration. The data suggests that if future missions could access this water, it might reveal crucial details about the planet’s past climate and its potential to support life.

Mars has long fascinated scientists because of its history of water. Evidence from previous missions points to ancient lakes, river channels, and deltas, suggesting that Mars was once a much wetter environment. However, the planet lost its atmosphere more than 3 billion years ago, leading to a significant drop in surface water. While some water remains trapped as ice at the polar caps, this does not account for all the planet’s “lost” water. The new findings suggest that much of it might have filtered into the Martian crust and is now stored in this deep reservoir.

The challenge of accessing this water is significant. Drilling to such depths on Mars would require substantial resources and advanced technology. Nonetheless, this discovery offers a new avenue for research and exploration. The presence of liquid water at these depths raises intriguing questions about Mars’ potential to harbour life, past or present. Understanding this reservoir could help scientists learn more about the Martian water cycle and its implications for the planet’s habitability.

Overall, the discovery of this underground water reservoir marks a significant advancement in our understanding of Mars. As we continue to explore the planet, this finding will play a crucial role in shaping future missions and research into the history and potential of Mars.

Supermassive Black Hole Burps Matter at Near-Light Speeds After Consuming Gas Too Fast

A distant supermassive black hole has stunned astronomers by expelling matter at speeds nearing a third of light velocity after consuming material at an extreme rate. Designated PG1211+143, this cosmic powerhouse lies in a Seyfert galaxy 1.2 billion light-years away and boasts a mass 40 million times greater than the Sun. Researchers using the ESA’s XMM-Newton X-ray telescope tracked an influx of gas equivalent to 10 Earths over just five weeks, only to find the black hole burping out excess matter at around 0.27 times the speed of light.

Supermassive Black Hole’s Outflows May Halt Star Formation and Alter Galaxy Evolution Permanently

As per a report in the journal Monthly Notices of the Royal Astronomical Society, these ultra-fast outflows followed the inflow by a delay of a few days, heating the surrounding active galactic nucleus (AGN) to millions of degrees. The radiation pressure generated was powerful enough to push out surrounding gas, potentially starving the black hole’s galaxy of star-forming material. This feedback loop, scientists suggest, might represent the transition from active star-birth sites to galaxies entering a quieter period.

The winds ejected at more than 181 million mph most likely blew away clouds of cold gas, which were necessary for stellar births. The evidence found allowed Pounds to observe a black hole as it grew, even though there is not much matter to feed the black hole, even if it is large.

This discovery can enable people to understand the influence of quasars and AGNs on galaxy life cycles. High-speed ejections of outflowing matter paralyse the star-formation process and turn star-forming regions into barren space. However, additional monitoring in pursuit to determine their frequency and global pattern of cosmic evolution.

Amazon’s Kuiper Launches 27 Satellites, Eyes 2025 LEO Broadband Rollout

Amazon's Kuiper Launches 27 Satellites, Eyes 2025 LEO Broadband Rollout

Demand for broadband connectivity is driving a surge in satellite constellations in low Earth orbit (LEO). LEO systems offer lower-latency links to remote areas and the potential to connect underserved communities. Amazon’s Project Kuiper and SpaceX’s Starlink head this wave. GeekWire notes that each Kuiper launch is “another significant step toward competing with SpaceX’s global Starlink network”, and Amazon is joining a “growing list of companies” seeking to challenge Starlink in the rapidly evolving LEO broadband arena. Indeed, filings show Amazon expects Kuiper to begin offering service by 2025.

Project Kuiper’s Ambitious Launch Plans

According to Amazon, Kuiper project is now moving into full deployment. It first flew two prototype satellites in late 2023, and on April 28, 2025 it launched 27 production satellites aboard a United Launch Alliance (ULA) Atlas V rocket. Kuiper aims for roughly a 3,200-satellite constellation, and Amazon has pre-booked dozens of heavy-lift launches to build it. For example, Space.com reports Kuiper will require “more than 3,200 satellites… after 83 launches on Atlas V, ULA’s Vulcan, Blue Origin’s New Glenn and Arianespace’s Ariane 6 rockets”. In December 2023 Amazon also secured three SpaceX Falcon 9 launches. These multi-provider launch contracts (costing many billions) are intended to spread schedule risk and ensure Kuiper’s constellation is delivered on time.

Amazon expects to begin customer service in late 2025, driving its schedule. To meet this timeline, it has reserved dozens of launch slots on Atlas V, ULA’s new Vulcan, Blue Origin’s New Glenn, Arianespace’s Ariane 6 and even SpaceX’s Falcon 9 rockets. These commitments ensure the required satellites will launch quickly to meet Amazon’s deployment milestones.

Global Competition in LEO Broadband

SpaceX’s Starlink leads with over 7,600 satellites already in orbit. SpaceX has flown dozens of Starlink launches this year to expand coverage. Meanwhile, rivals aim even higher: China’s state-backed Guowang project plans roughly 13,000 satellites, and the Shanghai-led “Thousand Sails” (Qianfan) network targets about 14,000. SpaceNews noted that these Chinese launches “advance [China’s] ambitious LEO network to rival Starlink and other global systems”. This worldwide build-out underscores that LEO broadband is evolving into a critical new domain of internet infrastructure.

Soviet Venus Probe Kosmos-482 Re-enters Earth’s Atmosphere After 52 Years, Location Unclear

More than five decades after orbiting the Earth, the Soviet-era Venus probe Kosmos-482 re-entered the Earth’s atmosphere on May 10, 2025, this time perplexing scientists about its precise re-entry. The mission was first flung into space in 1972, but a rocket failure left the probe stuck in high orbit around Earth instead of sending it on a course to Venus. The spacecraft’s descent capsule, which weighed about 495 kilograms, is believed to have fallen to Earth in the Indian Ocean, off Jakarta. However, various tracking models pointed to different locations of the exact impact, evidencing the severe limitations of predicting re-entries of space debris.

Tracking Soviet Probe Kosmos-482’s Reentry Exposes Gaps in Space Object Forecasting Models

As per a report from Space.com, other organisations, including Roscosmos, the U.S. Department of Defence, and the European Space Agency, made conflicting predictions demonstrating just how hard it is to estimate when a space object will re-enter. The module’s robust design—built to withstand Venus’s intense conditions—likely enabled it to survive reentry, but atmospheric variability, object orientation, and solar activity complicated tracking efforts.

Experts suggest Kosmos-482’s descent illustrates the need for improved reentry models. “Even a small deviation can translate into thousands of kilometres on Earth’s surface,” noted Aerospace Corporation’s Marlon Sorge. The “oddball” shape of the lander and its ability to possibly skip across atmospheric layers further blurred precise modelling.

Some scientists, like Pavel Shubin, believe the capsule could still be afloat, while others argue it may have sunk beyond recovery. With reentry predictions still confounded by “unhelpful physics” and data gaps, Kosmos-482 serves as a reminder that better tools and open-source collaboration, like TU Delft’s Tudat, may be crucial to future space traffic safety and planetary defence.
