Swiss startup Sun-Ways has been given permission to test the first removable solar panels on railway tracks. However, there are concerns about the safety of this project. The trial will take place on a track in the western canton of Neuchâtel, Switzerland, over a three-year period starting in spring 2025. The solar panels will be rolled out like a carpet between the tracks and can be easily removed. While the initial project is small, Sun-Ways aims to expand this technology globally.

ISRO successfully launched the PROBA-3 mission, which studies the Sun's orbit with an 'occulting' device 

They believe that 50% of the world's railway lines could be equipped with their system. This innovative approach to solar panel installation builds upon similar experiments conducted on roadsides, reservoirs, and farms. Other companies are also exploring adding solar panels to railway sleepers. However, Sun-Ways is the first to patent a removable system, making it unique in the industry. This removable feature is essential for the regular maintenance of railway tracks.

How will it work?

A special train, made by a Swiss company, will lay solar panels along the train tracks. This train rolls along the tracks, unfurling pre-made solar panels. It can lay up to 1,000 square meters of panels each day. For three years, a test will be done on a 100-meter track. 48 solar panels will be added, costing about €623,000. The electricity produced will be sent to the main power grid to supply homes. Using it for trains is more complex.

ISRO is developing its own regional navigation system.

Key points:

 * Removable Design: The solar panels can be rolled out and removed as needed, allowing for easy maintenance of the tracks.

 * Global Potential: Sun-Ways envisions equipping 50% of the world's railway lines with this technology.

 * Safety Concerns: Despite the potential benefits, there are concerns about the safety implications of this project.

 * Innovative Approach: This project is part of a broader trend of exploring unconventional surfaces for solar panel installation, including roadsides, reservoirs, and farms.

In essence, Sun-Ways is pushing the boundaries of solar energy generation by utilizing an often-overlooked space: railway tracks.

ISRO and ESA are preparing to launch the Proba-3 mission, a collaborative project involving two spacecraft working in tandem to simulate a solar eclipse. This unique approach will allow for unprecedented observations of the Sun’s corona. The mission highlights the increasing collaboration between space agencies and the potential of advanced technology for groundbreaking research.

The mission will facilitate extended observations of the Sun’s outer atmosphere by simulating solar eclipses. This innovative strategy will help scientists understand the Sun’s behavior, particularly regarding the corona's extreme heat and solar wind acceleration.

Here are 10 key facts about the Proba-3 mission:
 * Joint Venture: Proba-3 is a collaborative effort between the Indian Space Research Organization (ISRO) and the European Space Agency (ESA).
 * Launch Vehicle: The mission will be launched by ISRO's reliable PSLV-XL rocket on December 5, 2024.
 * Formation Flying: The mission involves two spacecraft, the Coronagraph and the Occulter, flying in a precise formation 150 meters apart.
 * Solar Eclipse Simulation: The Occulter spacecraft will block the Sun's disk, allowing the Coronagraph to observe the Sun's faint corona.
 * Extended Observation: This innovative technique will enable continuous observation of the Sun's corona, unlike traditional methods limited to brief solar eclipses.
 * Scientific Goals: The mission aims to study the Sun's corona, understand its extreme heat, and investigate the acceleration of solar wind.
 * Technological Advancement: Proba-3 demonstrates advanced formation flying technology, crucial for future space missions.
 * Space Weather Insights: The mission will study the Sun's corona, providing valuable insights into space weather events that can impact Earth.
 * Global Collaboration: The partnership between ISRO and ESA highlights international cooperation in space exploration.
 * Building on Success: Proba-3 follows the successful launches of Proba-1 and Proba-2, which have contributed to Earth observation and space science.
The scientific goals of the Proba 3 mission

Proba-3 facts and figures

Launch date:

5 Dec. 2024

Mass:Coronagraph spacecraft 340 kg; Occulter spacecraft 200 kg
Orbit:High Earth orbit, 19.7 hours orbital period, 60,530 km apogee, 600 km perigee
Instrument:External coronagraph
Ground station:The mission antenna will be at Santa Maria des Azores, and the ground station at Redu. The Proba-3 mission seeks to enhance our knowledge of the Sun’s corona and the phenomena related to space weather. These phenomena include solar storms and coronal mass ejections, which can significantly impact Earth’s communication systems, satellite operations, and power grids.

International collaboration in space research
The Proba-3 mission emphasizes the significance of international partnerships in advancing space research and technology. The collaboration between ISRO and ESA highlights the increasing importance of global cooperation in achieving scientific milestones in space. The mission also demonstrates ISRO's growing capabilities in space technology, as the PSLV-XL rocket has been selected to launch the two spacecraft into orbit. This launch will mark the 61st flight of the PSLV and the 26th use of its PSLV-XL configuration.

What is a Blue Moon: Astronomy Facts, Frequency & Live Quiz

By Manish sharma November 09, 2024 , ,

Blue Moon: The Science and History Behind the Rare Lunar Event

What is a Blue Moon? A Blue Moon is a rare astronomical phenomenon when there are two full moons in a single calendar month. This typically occurs every two to three years. The term "Blue Moon" is believed to have originated from a misunderstanding of the old English phrase "Once in a blue moon." This saying was originally used to mean "never" or "very rarely," but it was later adopted to describe this beautiful event that happens once in a while.

What is a Blue Moon: Astronomy Facts, Frequency & Live Quiz

Why do Blue Moons occur?

Blue Moons occur because the lunar cycle (synodic month), which is about 29.5 days long, does not always align perfectly with the standard solar calendar month of 30 or 31 days. When a full moon falls near the very beginning of a month, there is a high statistical probability that a second full moon will appear right before the month ends.

Is the moon actually blue during a Blue Moon?

No, the moon does not change its physical color to blue during a Blue Moon. The name is simply a lyrical reference to the rarity of the event. However, on rare historic occasions, the moon can actually appear to have a bluish hue due to extreme concentrations of dust particles or volcanic smoke suspended in Earth's atmosphere acting as a natural color filter.

🌕 Cultural Significance: While Blue Moons hold no extra mechanical gravity or astronomical effect on Earth, they are historically associated with good luck, magic, and mystical symbolism across various ancient global cultures.

When is the Next Blue Moon? (2026 Update)

The last iconic Blue Moon occurred on August 31, 2023. If you missed that beautiful night sky, you are in luck! The next highly anticipated Blue Moon is set to occur this year on August 31, 2026!

Interesting Facts about Blue Moons:

  • The first recorded use of the term "Blue Moon" dates back to the year 1580.
  • The mathematical average frequency of Blue Moons per century is roughly 2.3 years.
  • A rare double Blue Moon in a single calendar year can happen only about four times every century.
