Japan Space Agency prepares to launch two space missions on one rocket



The mission was scheduled to launch on August 28, but weather forced the launch to be delayed. XRISM and SLIM are scheduled to launch on an H-IIA rocket from the Tanegashima Space Center in Japan on the night of September 6th.

Weather conditions for the launch are favorable, the rocket has already been transferred to the launch pad by Mitsubishi Heavy Industries, which built this rocket. But the weather is no guarantee – a late August launch attempt was canceled less than 30 minutes before liftoff, shortly after a JAXA commentator reported that the weather was “little changeable”.

There are only a few minutes a day for a favorable SLIM trip to the Moon, when the Earth’s orientation is ideal for the spacecraft to follow such a trajectory to get into lunar orbit. Therefore, JAXA has reserved launch days until September 15th in case of delays that could cause the mission launch window to be missed.

The XRISM telescope will study cosmic X-rays, which, unlike other wavelengths, can only be detected from outside the Earth’s atmosphere. It will measure changes in the brightness of celestial objects at different wavelengths. This data will provide insight into the chemistry of some of the most extreme places in space, such as the matter around black holes, the plasma in galaxy clusters, and the remnants of exploding massive stars.

One of the key instruments aboard XRISM is Resolve, an instrument that will collect spectroscopic data at a much higher resolution than the X-ray observatories already orbiting Earth. In order to measure the slightest changes in temperature when X-rays strike the surface of the instrument, Resolve must be cooled to just above absolute zero. The second tool, Xtend, will work to photograph the cosmos at a resolution comparable to how scientific instruments see it in an X-ray field. While Resolve zooms in, Xtend will zoom in on the imagery, giving scientists additional, higher resolution views of the same sources.

The compact robotic lunar lander is named SLIM. Its task will not be primarily in scientific research. Instead, the goal is to demonstrate a precision navigation system by landing approximately within the size of a football field from a target landing coordinate. The development of improved landing technologies will enable future spacecraft to land closer to areas of scientific interest.

After a successful launch, scientists and engineers will spend several months turning on the instruments and testing their operation. Scientific operations will begin in January, and the first results based on these data are expected in about a year.

Xiaomi Pad 5 and Xiaomi Pad 5 Pro tablets will receive MIUI 15 – this is good news. But there is also bad



Xiaomi Pad 5 and Xiaomi Pad 5 Pro tablets will

The XiaomiUI resource, which tracks the release of firmware for various Xiaomi, Redmi and Poco devices, shared details about software support for the Xiaomi Pad 5 and Xiaomi Pad 5 Pro tablet computers. There are two news here: good and bad.

Xiaomi Pad 5 and Xiaomi Pad 5 Pro tablets will receive MIUI 15 - this is good news.  But there is also bad

The good news is that the devices of the line (and there are three of them – Xiaomi Pad 5, Xiaomi Pad 5 Pro 5G and Xiaomi Pad 5 Pro WiFi) will receive MIUI 15, but the bad news is that this firmware will be based on Android 13, and not Android 14. Thus, the release of MIUI 15 will be the last major software update for these models.

Traces on Europa: JWST discovered carbon on Jupiter’s moon



Traces on Europa JWST discovered carbon on Jupiters moon

Known for its subsurface ocean of liquid water beneath its icy crust, Europa shares characteristics with Earth. While the presence of solid carbon dioxide on Europa’s surface had been discovered previously, studying the composition of the subsurface ocean remained a challenge for scientists.

The team used the James Webb Space Telescope’s infrared spectrograph to detect carbon dioxide in a region called Tara Regio. Using 320 x 320 kilometer resolution data and studying the area, scientists identified pockets of solid carbon dioxide in the disturbed ice sheet, indicating a connection between the surface and the subsurface ocean.

Dr. Samantha Trumbo, an astronomer at Cornell University, explains that previous observations with the Hubble Space Telescope have already indicated the presence of salt coming out of the ocean in the Tara Regio region. And the discovery of concentrated carbon dioxide further suggests that the carbon most likely does come from Europa’s subglacial ocean. While these findings do not directly indicate the presence of life, the discovery of such a connection is a significant step in understanding Europa’s potential for habitation.

Further detailed analyzes of Europa are planned for the coming years, with NASA’s Europa Clipper mission scheduled to launch next year in 2024, and the European Space Agency’s JUICE spacecraft approaching Europa in 2030. These missions will provide more detailed observations and data to further our understanding of Europa’s composition and how it could potentially support life.

Satellites of the future: AI autonomy and cloud system will become a reality



Satellites of the future AI autonomy and cloud system will

The principal investigator at the SmartSat Cooperative Research Center (CRC) says future satellites will have the ability to make autonomous decisions, be equipped with artificial intelligence, and be able to operate in their own cloud system.

In June, a research project called SCARLET (SpaceCraft Autonomy Research Laboratory) was launched to implement this idea.

“Australia has enormous expertise in software, technology and artificial intelligence. And now our plan is to transfer this experience to space,” says Zubert, who worked at NASA for almost ten years.

Once they reach orbit, satellites and other spacecraft are relatively simple technology. They can take pictures or collect data, but this information must be transmitted to Earth and it takes time to receive the data. Due to the way data is transmitted to Earth and the constant movement of satellites, it can take up to a day to receive the information you need.

An excellent example is the early detection of fires or smoke. A SmartSat project called Kanyini is exploring this possibility using an artificial intelligence algorithm that analyzes images directly on board the satellite. To test the technology, the developers plan to demonstrate early smoke detection using AI processing on satellite images, where spectral bands are analyzed to distinguish smoke from other signals that may look similar, such as clouds or fog.

The delay in receiving data also affects how satellites are controlled in space. In most cases, satellites in low Earth orbit must be individually tracked and instructed to move out of the way of other satellites or other objects that may pose a potential collision hazard.

It’s fine if we only have a few satellites, but with “constellations” like Starlink that have 42,000 satellites, overpopulation begins. How to control such a “constellation”? To do this, it is necessary to give satellites autonomy.

The last and most complex type of future satellite is the “space cloud” – a network of interconnected satellites in which there is little or no human intervention. In such a space cloud, satellites of various architectures can perform their own specific tasks: take pictures, process data, and a third one can transmit data to Earth. At the same time, they all interact with each other and avoid collisions.

This will significantly speed up the processes of discovering, analyzing and communicating critical information.
