NASA is advancing technologies for autonomous spacecraft designed to explore “ocean worlds,” such as Europa and Enceladus, two of the most promising candidates for extraterrestrial life. According to a NASA report, the Ocean Worlds Lander Autonomy Testbed (OWLAT) and Ocean Worlds Autonomy Testbed for Exploration, Research, and Simulation (OceanWATERS) are key initiatives for enhancing robotic missions capable of operating in these challenging environments.

Both OWLAT, developed at the Jet Propulsion Laboratory (JPL), and OceanWATERS, created at Ames Research Center, simulate lander operations under low-gravity and icy surface conditions. OWLAT includes a physical testbed with a robotic arm and tools for sampling, while OceanWATERS offers a virtual environment replicating Europa’s conditions. These systems aim to prepare robotic missions for long communication delays, harsh terrain, and limited energy resources.

The Role of OWLAT and OceanWATERS

OWLAT, featuring a Stewart platform for simulating low-gravity dynamics, enables real-world testing of lander hardware and software. It includes force sensors, a robotic arm, and interchangeable tools for sampling. The system’s autonomy software ensures operations remain within safety bounds while executing commands via a Robot Operating System (ROS) interface.

OceanWATERS, a simulation-based system, provides a virtual landscape where autonomous decision-making algorithms are tested. Using Europa-like terrain models, it evaluates sample collection, terrain interaction, and energy efficiency. Fault injection tools allow researchers to simulate and resolve potential system failures.

Collaborative Research Outcomes

Research teams funded by the Autonomous Robotics Research for Ocean Worlds (ARROW) and Concepts for Ocean Worlds Life Detection Technology (COLDTech) programmes have utilised these platforms. According to NASA, projects ranged from fault-detection mechanisms by Dr Eric Dixon of Lockheed Martin to terrain-adaptive autonomy led by Dr Melkior Ornik at the University of Illinois.
These developments, as noted in official publications, mark progress towards self-reliant landers capable of probing icy moon surfaces and potentially uncovering signs of life.

Ancient Tel Dan Temple Reveals Centuries-Old Phoenician Ritual Bathing Traditions

Ancient Tel Dan Temple Reveals Centuries-Old Phoenician Ritual Bathing Traditions

A new archaeological find proves that ritual cleansing was a component of religious practice at an ancient sanctuary in northern Israel in the time of the kingdom of Israel. The sanctuary was equipped with a unique bathhouse, thought to have been used by the priests for ritual bathing. There, the diggers discovered two spaces — one room with yellow plaster, which had a dressing area, and another with walls of blue plaster and a basin — that offer a rare glimpse into how water was used in rituals of sacred purification. The discovery adds new depth to understanding Near Eastern religious practices linked to city-based deity worship.

Ancient Tel Dan Sanctuary Reveals Ritual Bathing Traditions Linked to Mysterious Deity Worship

According to a report published in Levant by Dr. Levana Tsfania-Zias, the sanctuary included a modest two-part bathing unit—featuring a yellow-plastered dressing room and a blue-plastered basin—suggesting ritual use by the priestly class. Unlike full-immersion baths, and because it is not heated, the basin’s size means worshippers might have washed themselves while standing, with cold spring water that flows into the Jordan from outlets nearby.

The first temple, constructed on a Middle Bronze Age rampart, had a tripartite plan of porch, cella, and adyton. A limestone fragment with inscriptions in both Greek and Aramaic, discovered in 1976, names an obscure deity and was almost certainly invoked in the central sanctuary of Dan. Scholars believe the deity’s identity remains uncertain due to the regional naming customs of ancient Near Eastern cities.

Following the destruction of the first temple by the Seleucids, a new temple was erected in its place, which preserved the bathing. After a 2-century gap, the site re-emerged in the Middle–Late Roman period for new purposes. Pilgrims were cleansed in a Fountain House, using primitive clay vessels that were likely smashed after use — a process mirrored in biblical texts describing ritual purity.

As so much of the sanctuary at Tel Dan remains in question, the scholars emphasised the significance of the site for the region. Dr. Tsfania-Zias believes the site would have been an attraction for both locals and visitors, something reinforced by imported ceramics and multilingual inscriptions that hint at a wider spiritual attraction. Deeper excavations could yet reveal what other deity or practices characterised this sacred spot in ancient times.

James Webb Telescope Spots Planet Formation in Harshest Known Galactic Environments

Planets can even form in some of the most inhospitable parts of the galaxy – so says new data from the James Webb Space Telescope (JWST). While attempting to study the planets that may be forming within one of the Milky Way’s most UV-rich star-forming regions, astronomers learnt that a planet-forming disk (dubbed XUE 1) has in fact been able to survive, despite extreme ultraviolet (UV) lightning that was once thought to be too harsh to allow planetary formation. The results expand the address in the universe where Earth-like planets may spawn.

Webb Telescope Detects Water in Planet-Forming Disk Exposed to Extreme UV Radiation in Deep Space

As per a report published in The Astrophysical Journal on May 20, XUE 1 orbits a young star in a region bombarded by UV radiation thousands of times more intense than what Earth’s solar system has ever experienced. Researchers from Penn State and the Max Planck Institute observed the far-flung disk, at a distance of 5,500 light-years with JWST’s Mid-Infrared Instrument (MIRI). Thermochemical modelling of the data established fundamental disk properties such as the temperature, density, and chemical composition of the gas.

Most remarkably, the mini disk contained water molecules — a key ingredient for life — despite the harsh radiation. The disk’s inner regions, including where hard, rocky planets like Earth might form, are seemingly shielded from the dangerous UV radiation bombarding the outer layers, according to the researchers. This safe zone could enable Earth-like worlds to form in places long believed unlikely.

The JWST-based model used synthetic spectra to compare with observed data and uncover the chemical behaviour of the disk material. Before these observations, scientists expected such environments to be too disruptive for planet formation. But the new data paints another picture, showing that planet-forming disks may, in fact, persist and even prosper in UV-rich surroundings.

The finding revamps astronomers’ view of how planets form and opens new possibilities in the search for habitable worlds. Scientists now suspect that not even extreme star-forming zones may be as deadly as they appeared to be. With more JWST research ahead, these cosmic nurseries may hold even more surprises — and more hope of finding Earth-like planets in other parts of the universe.

Massive X-Class Solar Flare Erupts, Causing Widespread Pacific Radio Blackouts

Massive X-Class Solar Flare Erupts, Causing Widespread Pacific Radio Blackouts

A powerful X1.9-class solar flare blasted out of the sun’s active region 4114 on June 19, peaking at 9:50 p.m. EDT (0150 GMT, June 20), and led to a shortwave radio blackout over the Pacific Ocean and, in large part, for Hawaii. Although the flare was accompanied by a sizable eruption of X-ray and ultraviolet light, it did not appear to be associated with a very powerful coronal mass ejection (CME), so there will be no auroras for hopeful skywatchers at this time. The energetic flare, however, destabilised a substantial magnetic filament in the southern hemisphere of the sun, hinting at more activity to come.

X1.9 Solar Flare From Sunspot 4114 Disrupts Radio Signals, Sparks Fears of Future Geomagnetic Storms

As per Space Weather Live and spaceweather.com reports, the electromagnetic radiation from the flare reached Earth within minutes, ionizing the upper atmosphere and disrupting shortwave radio communication below 25 MHz. In the Pacific region, ham radio operators reported an abrupt loss of signals following the peak of the flare. That happens due to a powerful solar disturbance that collides with the Earth’s ionosphere, increasing electron density and weakening the ability to absorb high-frequency signals. The outcome is signal attenuation or loss, as normally occurs during periods of intense solar activity.

Solar flares are ranked in strength, and X-class flares are the most intense ones. The flares from sunspot 4114 — rated at X1.9 — are one of the strongest in the current solar cycle. It follows an earlier eruption from the same region just days ago, rated at X1.2. The region has now drawn close monitoring due to its continued magnetic complexity and explosive potential.

Although no CME accompanied the latest flare, experts suggest future eruptions from region 4114 could be more geoeffective. If a CME is launched in subsequent flares, geomagnetic storms and auroral activity may follow.

Space weather forecasts and aurora updates are available on NOAA’s 3-day geomagnetic outlook and dedicated solar activity blogs.
