NASA has shut off one of Voyager 2’s scientific instruments to preserve its remaining power as it journeys through interstellar space. The spacecraft, launched on 20 August 1977, is currently positioned 12.8 billion miles from Earth and is exploring beyond the solar system. Since leaving the heliosphere on 5 November 2018, Voyager 2 has been studying the interstellar environment using four active science instruments. However, as the probe’s power supply gradually declines, NASA has had to make the tough decision of deactivating another instrument.

Managing diminishing power supplies

Voyager 2, along with its counterpart Voyager 1, is powered by decaying plutonium, which diminishes its available energy by around 4 watts each year. To extend its operational life, NASA has progressively turned off non-essential systems and some instruments. As of now, six of the spacecraft’s ten original instruments have been deactivated. On September 26, 2024, the decision was made to switch off the plasma science instrument, which had played a pivotal role in confirming the probe’s exit from the heliosphere by detecting the drop in solar particles.

Key data from the plasma science instrument

The plasma science instrument featured four “cups” to measure charged particles, three of which were pointed towards the Sun and monitored solar winds while inside the heliosphere. After the spacecraft moved beyond the heliosphere, these cups stopped collecting data, leaving only one operational. This remaining cup provided useful data at intervals when Voyager 2 performed its periodic 360-degree rotation.

Voyager 2’s future

NASA’s Jet Propulsion Laboratory confirmed that the plasma instrument was turned off without any complications, and the spacecraft continues to operate normally. As the remaining instruments collect valuable data, engineers will continue to monitor the probe’s energy reserves to determine when further shutdowns will be necessary, allowing the mission to continue for as long as possible.

Newly Detected Seaborgium-257 Offers Critical Data on Fission and Quantum Shell Effects

German Scientists at GSI Helmholtzzentrum für Schwerionenforschung found a new superheavy isotope, 257Sg, named Seaborgium, which reveals unexpected details about the stability and nuclear fission. This study was published in Physical Review Letters and describes how this isotope, made by fusing chromium-52 with lead-206, survived for 12.6 milliseconds, longer than usual. The rare longevity and decay into 253Rf provide new indications of how K-quantum numbers or angular momentum impact the fission resistance. The findings fill in the gaps and give us an understanding of the effects of quantum shells in superheavy nuclei, which is crucial for preventing immediate disintegration.

Challenging Traditional Views on K-Quantum Numbers and Fission

As per the study by GSI, it challenges conservative views on how K-quantum numbers impact fission. Previously, it was found that the higher K values lead to greater fission hindrance, but after getting the findings from the GSI team, a more complex dynamic emerged. They found that K-quantum numbers offer hindrance to fission, but it is still ot known that it is how much, said Dr. Pavol Mosat, the study’s co-author.

Discovery of First K-Isomeric State in Seaborgium

An important milestone is the identification of the first K-isomeric state in seaborgium. In 259Sg, the scientists found that the conversion of the electron signal occurs 40 microseconds after the nuclear formation. This is clear evidence of the high angular momentum K-isomer. These states have longer lifetimes and friction in fission in a more effective way than their ground-state counterparts.

Implications for the Theorised Island of Stability

This discovery by the scientists provides key implications for the Island of stability, which has long been theorised. It is a region where superheavy elements could have comparatively long half-lives. If K-isomers are present in the still undiscovered elements such as 120, they can enable scientists in the detection of nuclei that would otherwise decay in just under one microsecond.

Synthesising 256Sg with Ultra-Fast Detection Systems

This team of German Scientists under GSI is now aiming to synthesise 256Sg, which might decay quicker than observed or predicted. Their success is dependent on the ultra-fast detection systems created by GSI, which are capable of capturing events within 100 nanoseconds. This continued research by the team may help in reshaping the search and studying the heaviest elements in the periodic table.

NASA CODEX Telescope on ISS Reveals Hidden Secrets of the Sun’s Corona

A mini solar telescope aboard the International Space Station caught the first-ever images, which reveal the subtle and never-seen changes in the outer atmosphere of the Sun. It is known as the Coronal Diagnostic Experiment (CODEX) and has been designed to understand the solar corona, the outer layer of the Sun, in depth. This mini telescope functions like a coronagraph, which blocks the Sun’s disk to imitate the total solar eclipse. CODEX was delivered through SpaceX Dragon on November 5, 2024. It was mounted on the ISS using the Canadarm2 robotic arm on November 9, 2025.

Revolutionising Solar Observation

According to the report by NASA, the unique design of CODEX consists of an occulting disk the size of a tennis ball held by three arms made up of metal. It allows it to block the intense sunlight when imaging the faint corona. The first images were revealed on June 10, 2025, at the time of the American Astronomical Society’s meeting in Alaska. These comprised pictures of coronal streamers and footage of the temperature fluctuations in the outer corona over many days. This offers a fresh perspective on solar dynamics.

Measuring Solar Wind Like Never Before

CODEX is unlike the previous coronagraphs as it is the first to measure both the speed and temperature of the solar wind. There is a constant flow of superhot particles from the Sun. With the help of four narrowband filters, in which two are used for determining the temperature and two for speed, astronomers compare brightness to decode these properties, which helps in solving the mystery of how the solar wind reaches 1.8 million degrees Fahrenheit.

Tackling the Solar Weather Challenge

To know the solar wind, it is crucial to predict the geomagnetic storms triggered by the coronal holes. Shortly, the storms observed on June 13, 2025 and June 25, 2025, caused auroras because of these events. After refining the analysis of solar wind, CODEX can help in mitigating and forecasting such kind of disturbances.

A Timely Launch Amid Solar Peak

NASA’s CODEX started operations at a suitable moment, just as the current solar maximum comes to its end. As the magnetic field of the Sun shifts during the solar battle zone, CODEX is ready to catch the critical data that can change our understanding of the weather in space.

Rocket Lab Sets Record with 'Symphony in the Stars' Launch for Confidential Client

Rocket Lab has launched the mysterious satellite on Saturday, June 28, 2025, making another milestone, as it is the first ever record of their missions. At 12:38 p.m. IST, the Electron rocket lifted from Launch Complex 1 in Mahia. The mission is known as “Symphony in the Stars,” and carried a single spacecraft above 650 kilometres above the Earth’s orbit. This satellite was deployed for a confidential commercial client, and the details are still not revealed. However, Rocket Lab has made a record by doing so.

Confidential Launch, Yet Revealed

As reported by Rocket Launch, it was the 68th Electron launch of Rocket Lab overall and the tenth mission of 2025. Even after its confidentiality, it was confirmed that it had successfully launched into space. Rocket Lab shared its news on social media regarding Mission Success and confirmed payload deployment. They further wrote, “Music to our ears for “Symphony in the stars.” It was one of the two missions dedicated to the same client, with the second launch to happen later in 2025.

This launch went through 48 hours after the “Get the Haw Outta Here mission.” This set a new record for the company. This different and every achievement highlights the reliability and ability of Electron Rocket Lab to offer responsive and repeatable access to space. It is a significant milestone, especially for the demand for fast satellite deployment continuity to arise.

Rocket Launch’s Occupied Month

It was a busy month for Rocket Launch as it went through the completion of four missions alone. Further, in the queue, after “Symphony in the Stars,” they launched “Full Stream Ahead,” then “The Mountain God Guards,” and “Get The Hawk Outta Here.” Every mission has supported commercial satellite operators, which demonstrates the versatility of Electron in rapid deployment schedules and handling.
