The Breakthrough Starshot program aims to demonstrate a proof-of-concept for ultra-fast, light-driven nano-spacecraft, and lay the foundations for a first launch to Alpha Centauri within the next generation. Secondary goals are Solar System exploration and detection of Earth-crossing asteroids. The spacecraft would make a flyby of, and, possibly photograph any Earth-like worlds that might exist in the system. Target planet edit The European Southern Observatory (ESO) announced the detection of a planet orbiting the third star in the Alpha Centauri system, Proxima Centauri in August 2016. The planet, called Proxima Centauri b, orbits within the habitable zone of its star. It could be a target for one of the Breakthrough Initiatives' projects. In January 2017, Breakthrough Initiatives and the European Southern Observatory began collaborating to search for habitable planets in the nearby star system Alpha Centauri. The agreement involves Breakthrough Initiatives providing funding for ...
India Republic Day -- Republic Day 2021 Parade Timetable Chief Guest Security Bouquets: The parade normally considers thousands of people and foreign dignitaries invited to see the parade. Still the number of guests and people has been restricted due to the coronavirus pandemic this time. Republic Morning 2021 Parade Timings Primary Guest Delhi Metro Solutions: India will celebrate it has the 72nd Republic Day in January 26. This day is usually marked to celebrate the particular date on which the Constitution connected with India came into being in 1950. On this day the Republic Day parade takes place to display the military might and also the rich cultural heritage with the country. The parade normally sees thousands of people and foreign dignitaries invited to see the attend. However the number of guests and attendees has been restricted a result of the coronavirus pandemic this time. This year there will be no chief invitee or foreign dignitaries in Republic Day. The number of vi...
The Starshot concept envisions launching a "mothership" carrying about a thousand tiny spacecraft (on the scale of centimeters) to a high-altitude Earth orbit for deployment. A phased array of ground-based lasers would then focus a light beam on the crafts' sails to accelerate them one by one to the target speed within 10 minutes, with an average acceleration on the order of 100 km/s2 (10,000 ɡ), and an illumination energy on the order of 1 TJ delivered to each sail. A preliminary sail model is suggested to have a surface area of 4 m × 4 m. An October 2017 presentation of the Starshot system model examined circular sails and finds that the beam director capital cost is minimized by having a sail diameter of 5 meters. The Earth-sized planet Proxima Centauri b is part of the Alpha Centauri system habitable zones. Ideally, the Breakthrough Starshot would aim its spacecraft within one astronomical unit (150 million kilometers or 93 million miles) of that world. From this dist...
