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.

Blue Origin’s New Glenn Rocket Successfully Reaches Orbit on First Flight

Blue Origin achieved a significant milestone with the maiden launch of its New Glenn rocket. The vehicle lifted off from Cape Canaveral Space Force Station at 2:03 a.m. EST on January 16, 2025. Designed as a reusable orbital-class rocket, it marked a pivotal moment for the company’s ambitions in the spaceflight sector. The mission’s primary goal of reaching orbit was successfully accomplished approximately 12.5 minutes after launch, marking a significant achievement for the NG-1 test flight.

About the New Glenn Rocket

According to reports from Blue Origin, as reported by space.com, The New Glenn rocket, which is 320 feet tall, represents years of development. Initially targeted for a 2020 debut, its timeline was extended due to delays in producing its BE-4 first-stage engines. Blue Origin highlighted that the rocket’s reusable first stage underwent rigorous testing during this launch, including an attempt to land on a recovery ship named Jacklyn in the Atlantic Ocean. Although the booster did not successfully land, it executed planned reentry burns, providing valuable data for future missions.

Capabilities and Future Missions

The rocket is engineered to carry payloads of up to 50 tons to low Earth orbit. Comparisons are frequently drawn between New Glenn and SpaceX’s Falcon Heavy, with the latter boasting a slightly higher payload capacity. New Glenn’s reusability, aimed at up to 25 launches per booster, is expected to enhance cost efficiency.

As reported by space.com, Blue Origin has secured contracts with NASA, the U.S. Space Force, and private telecommunications companies. Among its upcoming missions is the deployment of Amazon’s Project Kuiper broadband satellites. NASA has also scheduled its ESCAPADE Mars mission for 2025 aboard New Glenn, contingent on the rocket proving reliable.

Test Payload Validated

On this flight, a prototype of Blue Origin’s Blue Ring spacecraft was carried to validate key communication and tracking technologies. This system is being developed under the Defense Innovation Unit’s Orbital Logistics Program to transport payloads to various orbits. The launch has been described by Blue Origin as a critical step towards expanding its role in commercial and governmental space missions.

The Future of Armour? New Chainmail-Like Material Shows Promise

A new two-dimensional (2D) material that combines exceptional strength with flexibility has been created by a team led by Northwestern University. Described as resembling interlinked chainmail, this innovative material is lightweight and holds potential for applications such as advanced body armour and other high-performance uses. The breakthrough is credited to the development of a scalable polymerisation process that creates densely packed mechanical bonds, reportedly achieving a record-breaking 100 trillion mechanical bonds per square centimetre.

Structure and Development Process

According to the research published in Science, this material is the first of its kind—a 2D mechanically interlocked polymer. The team utilised X-shaped monomers, arranging them in a crystalline structure to facilitate the formation of mechanical bonds. William Dichtel, Robert L. Letsinger Professor of Chemistry at Northwestern University, noted in a statement, as reported by phys.org, that this novel polymer structure offers unique resistance to tearing.

He explained that the material can dissipate applied forces in various directions due to the freedom of movement within its mechanical bonds. Madison Bardot, a doctoral candidate and the study’s first author, reportedly devised the concept for the material’s formation. Describing the process as “high-risk, high-reward,” Dichtel attributed the success to rethinking traditional approaches to molecular crystal reactions. Layers of the resulting interlocked polymer sheets are said to provide both rigidity and flexibility, while their structure has been confirmed using advanced electron microscopy techniques by researchers at Cornell University.

Enhanced Properties and Applications

The material’s inherent strength inspired researchers at Duke University, led by Matthew Becker, to incorporate it into Ultem, a robust polymer used in extreme conditions. A composite containing just 2.5 percent of the new material reportedly increased Ultem’s toughness significantly. Dichtel suggested that the polymer could serve as a specialised material for ballistic fabrics and lightweight, protective gear.

The study was dedicated to the late Sir Fraser Stoddart, who pioneered the concept of mechanical bonds and was awarded the Nobel Prize in Chemistry in 2016 for his contributions to molecular machines.
