Space BD will assist in creating and executing the development roadmap for the Benibana Sat Project.

Space BD intends to expand support for development collaboration and human resource development as a model case to municipalities, educational institutions, and companies nationwide seeking to enter the space industry.

The spacewalk was scheduled to last six and a half hours and included tasks such as installing a retrofit kit for future solar array deployment, wiring cables, installing jumper cables, taking photographs of hardware, and collecting microbial samples.

The spacewalk was to be conducted by veteran astronaut Mike Fincke and relatively new crew member Zena Cardman.

NASA plans to announce additional information, including a new date for the spacewalk.

NASA stated that the situation related to the medical issue is stable but did not disclose further details due to medical privacy concerns.

NASA postponed the spacewalk originally scheduled for January 8 due to a medical issue involving an astronaut aboard the International Space Station (ISS).

The observed variations in structural and polarization properties over a span of five days highlight the highly dynamic nature of the magnetic field structure within the relativistic jet.

Rapid proper motions suggest that within these inner regions, the kinetic energy of particles exceeds the magnetic energy, favoring the development of Kelvin-Helmholtz instabilities.

The observations were conducted on April 5 and April 10, 2017, revealing substantial changes in both structure and polarization properties within five days.

The high-resolution data from the Event Horizon Telescope allows direct visualization of these structures, providing concrete evidence of the interaction between jet instabilities, shocks, and helical magnetic fields.

OJ287 is an ideal candidate for these observations, where two supermassive black holes orbit each other, known for its spectacular periodic outbursts.

The source of observation is called OJ287, located 1.6 billion light-years away.

The twisted structure of the jet in OJ287, combined with the high degree of polarization and the evolution of polarization angles, indicates complex interactions between Kelvin-Helmholtz instabilities and shocks in a jet permeated by a helical magnetic field.

The research team captured two shock waves moving at different speeds along the jet coming from OJ287.

The observed variations in the jet are typically interpreted as a precession effect, but the observations indicate non-ballistic motions of these components.

The analysis in polarized light reveals three prominent polarized components within the jet, with significant variations in their polarization angles over five days.

These instabilities can generate helical distortions that manifest as a twisted structure like that observed in OJ287.

The radial distribution of polarization angles suggests the presence of a reconfinement shock, capable of compressing the magnetic field and producing enhanced polarization.

Observational distinction between effects due to geometry and effects due to real physical processes is a key step for comparing theoretical models with observations.

The total intensity images of the jet show a strongly twisted structure extending northwest, with components exhibiting apparent superluminal motions up to approximately 22c.

The two inner components of the jet show polarization angles rotating in opposite directions, with the faster component rotating counterclockwise at about 3.7 degrees per day.

The Event Horizon Telescope observations probe the jet on scales of 10-100 times the black hole's gravitational radius, where the jet is launched and magnetic fields play a crucial role.

The observations revealed a third polarized component in the jet.

The Event Horizon Telescope achieved a resolution equivalent to identifying a tennis ball on the surface of the Moon.

The team spatially resolved individual shock components and their interaction with Kelvin-Helmholtz instabilities for the first time in a black hole jet.

Astronomers have observed a candidate galaxy hosting a supermassive binary black hole system with unprecedented angular resolution thanks to the Event Horizon Telescope.

The slower component of the jet rotates clockwise at around 2.5 degrees per day.

The research indicates that the Event Horizon Telescope is not only capable of producing spectacular images but also useful for understanding the physics governing black hole jets.

The outermost polarized component, located approximately 200 microarcseconds northwest of the core, is strongly polarized with a peak of about 25 percent.

This result directly confirms the existence of a helical magnetic field permeating the collimation and acceleration regions of the jet.

The opposite rotations of the components are considered significant evidence of the interactions between shock components and Kelvin-Helmholtz instabilities.

OJ287 was observed for the first time with the Event Horizon Telescope at a wavelength of 1.3 mm, achieving an exceptional angular resolution of 18 microarcseconds.

The model proposed includes Kelvin-Helmholtz instabilities creating filamentary structures that interact with propagating shocks, compressing the magnetic field and amplifying emission in specific regions of the jet.

The Neil Armstrong Operations and Checkout Building is dedicated to the assembly and verification of crewed spacecraft.

Airbus is the prime industrial contractor for ESM-4 on behalf of the European Space Agency (ESA).

ESA is supplying the module to NASA as part of Europe's contribution to the Artemis program.

The arrival of ESM-4 in Florida helps maintain the integration schedule for the Orion vehicle and reduces risks associated with final preparation phases.

The testing phase for ESM-4 is essential to validate the overall performance of the vehicle.

The European contribution, coordinated by Airbus and ESA, underscores the central role of international cooperation in developing future crewed lunar missions.

The arrival of ESM-4 is a key step in preparing the vehicle for missions to the lunar Gateway station.

ESM-4 will undergo final testing and integration with the Orion capsule.
