Space News ,U.S :- The Odysseus lunar lander, affectionately known as "Odie" or IM-1, built by Intuitive Machines, faced an unexpected turn of events during its historic mission on the lunar surface. Initially described as "upright" after touchdown, it was later revealed in a news conference that the lander was actually sideways. This surprising revelation came after the spacecraft's descent, raising concerns about the mission's success. However, despite challenges, the Odysseus lander remains in stable condition, demonstrating resilience and pioneering achievements.The Unforeseen Tilt:Intuitive Machines CEO, Steve Altemus, disclosed that data analysis indicated the lunar lander was likely tilted on its side due to catching one of its feet on a lunar rock during descent. Altemus demonstrated the issue using a small model of the lander during a news briefing. Despite the tilt, he assured that only one piece of cargo, a piece of art from a commercial customer, was on the side facing the lunar surface.Altemus emphasized that the spacecraft maintained stability, with solar panels effectively capturing sunlight and fully charging its batteries. Notably, experimental technology payloads from NASA were successfully tested, achieving key mission objectives.Overcoming Navigation Challenges:Before descent, Intuitive Machines discovered a faulty navigation equipment piece on Odysseus. Facing a potential mission loss, the team opted for a creative solution. They bypassed the malfunctioning equipment and utilized an experimental NASA instrument onboard – the Navigation Doppler Radar (NDL), developed at NASA’s Langley Research Centre.Altemus described the initial realization of the navigation issue as "like a punch in the stomach." Engineers had to operate like hackers, patching in data from NASA's NDL intended for a simple demo flight. The unconventional approach proved successful, allowing the spacecraft to soft-land on the moon. This marked a historic achievement, as no U.S. spacecraft had achieved this since the Apollo 17 mission in 1972, and Odysseus became the first commercial spacecraft to soft-land on the lunar surface.Assessing Mission Success:Despite the triumph, challenges persist as NASA and Intuitive Machines work together to assess whether Odysseus can fulfill all its science objectives. Joel Kearns, deputy associate administrator for exploration in NASA’s Science Mission Directorate, mentioned ongoing evaluations to determine if certain measurements are still possible with the new orientation of the lander.Issues related to data gathering speed and consistency are also being addressed. However, Kearns commended the mission as a significant accomplishment, especially given its focus on the lunar south pole, a key area for future human Artemis missions aiming to return astronauts to the moon later in the decade.The Road Ahead:Intuitive Machines is actively working to evaluate Odysseus's capabilities on the lunar surface and confirm the spacecraft's physical state after the unexpected tilt. The company expressed hope in obtaining images captured by the lander during its time on the moon and plans to deploy EagleCam, a device aboard Odysseus, to capture images from a distance.Tim Crain, Intuitive Machines’ chief technology officer, provided insights into Odysseus's operational timeline on the lunar surface. The spacecraft is projected to operate for about nine days, slightly longer than the initial estimate of seven days. After this period, the lunar night will set in, causing the sun to move beyond the solar arrays, leading to a deep cold that the electronics may not survive.The Odysseus lunar lander's sideways adventure on the moon has added unexpected twists to its mission. Despite challenges, the spacecraft remains in stable condition, showcasing the resilience and ingenuity of the team at Intuitive Machines. The successful use of innovative solutions, such as the Navigation Doppler Radar, highlights the adaptability of space exploration technologies. As Odysseus continues its lunar journey, scientists and engineers eagerly await the insights it will provide and the data it will gather, contributing to our understanding of the lunar surface and paving the way for future lunar exploration missions.

Space News , India :- The Plasma Analyser Package for Aditya (PAPA) payload onboard the Aditya-L1 has been operational and performing nominally. Its advanced sensors have successfully detected the impact of coronal mass ejections (CMEs) including those that occurred during February 10-11, 2024.PAPA is an energy and mass analyzer designed for in-situ measurements of solar wind electrons and ions in the low energy range. It has two sensors: the Solar Wind Electron Energy Probe (SWEEP, measuring electrons in the energy range of 10 eV to 3 keV) and the Solar Wind Ion Composition Analyser (SWICAR, measuring ions in the energy range of 10 eV to 25 keV and mass range of 1-60 amu). The sensors are also equipped to measure the direction of arrival of solar wind particles.The payload has been operational since December 12, 2023. Its observations during the Halo Orbit Insertion (HOI) phase are shown in Figure 1. The figure illustrates the time series of SWEEP electron energy spectra and total count observed during the HOI phase and the period preceding and succeeding it. It reveals about three-order magnitude change in electron counts from 10 eV to 3000 eV. The majority of electrons have energy below 40 eV. It displays an excellent signal-to-noise ratio and energy resolution. Drastic reduction in the electron energy spectra and the total count occurs during the HOI phase due to the change in payload orientation away from the sun direction during this orbit maneuvering period. This is also evident in the ion energy spectra observed using SWICAR (Figure 2).Figure 2 shows the time series of SWICAR ion energy spectra and integrated counts during the specified timeframe. It exhibits the expected patterns of ion energy spectra under normal space weather conditions. The ion energy spectrum indicates the dominance of protons (H+ @ 1 amu at around 800 eV) and alpha particles (He++ @ 2 amu at around 1600 eV). The ability of SWICAR to identify individual ion masses aligns with its design.The electron (SWEEP) and ion (SWICAR) energy spectra observed before and after the HOI phase are comparable.The data collected by PAPA revealed the occurrence of Coronal Mass Ejection (CME) events, notably on December 15, 2023, and during February 10-11, 2024, as shown in Figures 3 and 4. The CME on December 15, 2023, was a single event. PAPA observations during this period (Figure 3) showed an abrupt increase in total electron and ion counts and the time variations align with the solar wind parameters and magnetic field measurements obtained from the Deep Space Climate Observatory (DSCOVR) and Advanced Composition Explorer (ACE) satellites at the L1 point. In contrast, the observed variations in electron and ion counts during February 10-11, 2024 are the result of multiple minor events, with differences in the time variations of electrons and ions.The SWEEP and SWICAR sensors on PAPA-Aditya-L1 are currently making continuous observations of solar wind electrons and ions in the default mode, demonstrating that they are performing as per the design in all modes of operations. The observations made by PAPA emphasize its effectiveness in monitoring space weather conditions and its capability to detect and analyze solar phenomena.The PAPA payload is developed by the Space Physics Laboratory and Avionics Entity of the Vikram Sarabhai Space Centre (VSSC)/ISRO.

Space News ,World :- On Thursday, February 22, the United States experienced major cellphone outages, coinciding with two powerful tantrums from the sun. These solar flares, explosions of energy from the sun, occurred on the evening of February 21 and early morning of February 22. The first flare, labeled X1.8-class, happened at 6:07 p.m. ET on February 21, followed by another, an X1.7-class flare, at 1:32 a.m. ET on February 22. The National Oceanic and Atmospheric Administration (NOAA) mentioned that these flares came from a sun region displaying strong magnetic complexity.As of now, there is no evidence of Coronal Mass Ejections (CMEs) resulting from these events, but the possibility has not been ruled out, according to NOAA. Despite this, an alert was issued by NOAA for a solar radio emission at 6:58 a.m. ET on February 22, which sometimes accompanies strong CMEs and solar radiation storms.NASA's Solar Dynamics Observatory captured this image of an X1.8-class solar flare on Feb. 21, 2024. (Image credit: NASA/SDO)Coincidentally, widespread cellphone outages were reported across the U.S. on the same day as the solar flares. Major carriers like AT&T, Verizon, and T-Mobile reported tens of thousands of outages. While it's unclear if the solar flares caused the outages, the timing of the reports aligns with the flares. Some solar scientists, however, are skeptical about any direct connection between the solar flares and the cellphone outages. Solar astrophysicist Ryan French from the National Solar Observatory noted that flares typically affect the "dayside" of the Earth, and since the U.S. was not on the dayside during the events, it might just be a coincidence. The effects of these solar flares might linger for days. NOAA reported an "eruptive filament" seen exploding from the northwest quadrant of the sun's visible disk on February 21. While most of the energy is expected to pass ahead of Earth in its orbit, there's a possibility of a "glancing influence" on February 25, as per NOAA's forecast.NASA's Solar Dynamics Observatory captured this image of an X1.8-class solar flare on Feb. 21, 2024. (Image credit: NASA/SDO)NOA issued this warning about two X-class flare events that occurred on Feb. 21 and 22. (Image credit: NOAA)Image Credit: NOAASolar flares occur when magnetic energy builds up in the sun's atmosphere and is released in an intense burst of electromagnetic radiation. These flares are categorized by size into groups, with X-class being the most powerful, followed by M-class, C-class, B-class, and A-class, which are too weak to significantly impact Earth. The sun is currently entering the most active phase of its approximately 11-year solar cycle known as the "solar maximum." This phase could bring more space weather events, including communication blackouts and threats to orbiting spacecraft. On a positive note, it could also result in more widespread auroras globally.

This research provides unique insights into the behavior of the transient black hole X-ray binary during its 2018 outburst, led by researchers from IUCAA, Pune, along with contributors from India, the United Kingdom, Abu Dhabi, and Poland.Positioned approximately 9800 light-years away from Earth, MAXI J1820+070 is a transient black hole X-ray binary that gained significant attention within the astronomy community when first detected during its 2018 outburst using the MAXI instrument aboard the International Space Station (ISS). Due to its proximity to Earth and remarkable brightness, ranking as the second brightest object in the X-ray sky, MAXI J1820+070 sparked numerous observing campaigns across various electromagnetic bands.Equipped with three X-ray payloads and a UV telescope, AstroSat captured soft and hard X-ray emissions as well as far ultraviolet radiation, creating a detailed portrait of the regions surrounding the black hole in MAXI J1820+070. By collaborating with optical data from Las Cumbres Observatory and soft X-ray data from NASA's NICER mission, the research team gained a comprehensive understanding of the system's dynamics.The study divulges intriguing findings about the accretion states of MAXI J1820+070. Black hole X-ray binaries, including MAXI J1820+070, often exhibit multiple accretion states throughout an outburst. The study reveals distinctions between the hard and soft states, characterized by the emission of predominantly higher-energy X-rays from the corona surrounding the black hole in the hard state, and softer X-rays emitted by the accretion disk itself in the soft state. The research, utilizing advanced techniques, also unveiled the black hole's spin, providing insights into its fundamental properties.Additionally, the study establishes a compelling connection between X-ray emission from the inner regions near the black hole and optical/UV emission from the outer region of the accretion disk. Reprocessed radiation in the outer accretion disk emerges as a primary mechanism for generating optical/UV photons, with a notably higher proportion observed during the hard state.This research extends beyond the specific case of MAXI J1820+070, emphasizing the crucial role of AstroSat in advancing the understanding of transient black hole X-ray binaries. With its unique multi-wavelength capabilities, AstroSat paves the way for further exploration of diverse astrophysical phenomena, laying the groundwork for future endeavors in the field.The significance of this study is underscored by its highlighting of the importance of acquiring multi-wavelength spectroscopic data for X-ray binaries, providing novel insights into the intricate workings of these cosmic phenomena.The accompanying schematic diagram illustrates the geometries associated with the hard state (upper panel) and soft state (lower panel) of MAXI J1820+070, as deduced in this study. Various physical processes contributing to X-ray emissions are denoted by blue-colored arrows, while those responsible for optical/UV emissions are represented by red-colored arrows.

Technology News ,Israel :- A group of researchers led by experts from Tel Aviv University and the Volcani Institute in Rishon LeZion has made a breakthrough in improving the process of genetically cloning plants. This development could have a significant impact on modern agriculture.The key advancement, achieved after eight years of research, focuses on making the process of rooting cuttings from mature trees more efficient. This method, known as "cutting propagation," involves using a piece of a parent plant, such as a stem or branch, to grow a new plant.The traditional way of cutting propagation uses the plant hormone auxin to stimulate root growth. However, this method is not equally effective for all plant species, making widespread adoption challenging. Building on existing knowledge, the researchers aimed to enhance the effectiveness of auxin by exploring slow-release formulations.After extensive experimentation, the researchers developed a "library" of synthetic auxin varieties. Compounds showing promising results were identified and further refined, enabling prolonged auxin release within plant cells. This significantly increased rooting percentages in various plant species.The findings were recently published in the peer-reviewed journal Nature Biotechnology.To understand the enhancement's mechanisms, the researchers studied the mode of action of the new compounds using model plants. They discovered that the synthetic auxin in the compounds exhibited greater stability within plant cells. The researchers also identified a family of enzymes responsible for its release, paving the way for broader applications across different plant species.Research student Ohad Roth explained, "We identified compounds with a positive effect on the rooting process and focused on the most effective one. This compound allows high permeability to the plant with a prolonged release of the synthetic auxin, staying in the plant for up to a week and a half."The study's significance was highlighted by its success in propagating argan trees, historically challenging due to their reliance on sexual reproduction via seeds. The researchers successfully produced a large number of seedlings from elite selections, opening up possibilities for cultivating argan trees outside their native habitat.The upgraded treatment also showed promising results with other trees, including apple, poplar, and eucalyptus. For example, the rooting percentage of eucalyptus cuttings increased to 60%, up to six times higher than the standard method.The team believes that their findings will reduce the cost of rooting procedures, improve produce quality, and contribute to the development of new crops capable of adapting to challenging climate conditions.

Space News ,Japan :- On the evening of February 16, the H3 rocket achieved a significant milestone by successfully deploying its payloads into orbit. This success marks a remarkable recovery from its debut flight failure last year, positioning the H3 as Japan's promising future workhorse rocket.During a live webcast provided by the Japan Aerospace Exploration Agency (JAXA), a commentator expressed their excitement, stating, "I was so moved! The story of H3 will begin from today." JAXA offered real-time English translations for the original Japanese comments.JAXA, in collaboration with Mitsubishi Heavy Industries, has dedicated a decade to the development of the H3 rocket. Designed as an expendable, medium-lift rocket, it is set to replace the venerable H-2A, which has been in operation since 2001 and is scheduled for retirement later this year.Standing at either 187 feet or 207 feet (57 or 63 meters), depending on the choice of payload fairing, the two-stage H3 is equipped with newly developed liquid hydrogen-liquid oxygen LE-9 engines for the first stage. The upper stage features a single LE-5B-3, an advanced variant of the upper-stage engine on Japan's previous H-1 and H-2 vehicles.Configurable with two or four solid rocket boosters, the H3 can haul over 7.2 tons (6.5 metric tons) of payload to geostationary transfer orbit (GTO) in its most robust configuration. This is a significant improvement over the H-2A, which can deliver about 4.4 tons (4 metric tons) to GTO. Furthermore, the H3 is expected to be more cost-effective to build and operate, according to JAXA officials.Originally targeted for a 2020 debut, the H3 faced development delays, primarily due to challenges in developing the LE-9 engine. It eventually launched on March 6, 2023, carrying the Advanced Land Observing Satellite-3 (ALOS-3), also known as DAICHI-3, on its debut mission.However, the debut mission encountered issues as the H3's second-stage engine failed to ignite due to an electrical problem, resulting in the loss of the satellite.After almost a year, the H3 took off again from Japan's Tanegashima Space Center on February 16 at 7:22 p.m. EST (0022 GMT and 9:22 a.m. Japan Standard Time on Feb. 17). This time, it successfully carried two small Earth-observation satellites, CE-SAT-IE and TIRSAT, along with a 5,900-pound (2,600 kilograms) mass simulator called the Vehicle Evaluation Payload-4.The mission's primary goal was to evaluate the H3 rocket's performance and its payload deployment mechanism. Impressively, the rocket achieved all required milestones on time, including the successful ignition of its upper-stage engine, which had encountered issues in the previous mission.The upper stage reached orbit and deployed CE-SAT-IE, followed by the planned deployment of TIRSAT and the payload simulator. In a postflight update, JAXA confirmed the successful separation and controlled re-entry of the second stage, verifying the separation of the Vehicle Evaluation Payload-4 (VEP-4).The triumphant success of the H3's recent mission marks a significant step forward, solidifying its position as a reliable and resilient rocket for Japan's future space endeavors.
