NASA’s OSIRIS-Rex mission discovers evidence of water, particle plumes on asteroid Bennu among numerous other findings.
- Bennu is only slightly wider than the height of the Empire State Building and it is expected to contain unaltered material from the very beginning of our solar system.
- Bennu has a more rugged surface than expected. This posed a challenge for the mission team and forced it to alter its flight and sample collection plans, due to the rough terrain.
- Few of the particles ejected out of Bennu orbited it as satellites before returning to the asteroid’s surface.
- Bennu is a carbonaceous asteroid in the Apollo group and is a potentially hazardous object.
NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (Osiris-REx) mission is aimed at studying Bennu Asteroid and Osiris-Rex mission began orbiting the asteroid on December 31 last year. The Osiris-Rex mission is expected to return samples to Earth in 2023 and before attempting to obtain a sample from the asteroid, it will map out Bennu’s surface in detail and orbit the asteroid to calculate its mass.
The International Day of Happiness 2019 was celebrated on March 20 with the theme Happier Together, focusing on what we have in common, rather than what divides us.
International Day of Happiness
International Day of Happiness recognises the importance of happiness in the lives of people around the world. The concept of International Day of Happiness was conceptualised and materialised by UN special advisor Jayme Illien to inspire and spread a happiness movement globally and the first ever international day of happiness was observed on March 20, 2013.
Further to take forward the agenda of Happiness the United Nations has launched the 17 Sustainable Development Goals that seek to end poverty, reduce inequality, and protect our planet which are the three key aspects that lead to well-being and happiness.
Why March 20?
March 20 was chosen for International Day of Happiness 2019 for its significance as the March equinox. March equinox is a universal phenomenon felt simultaneously by all of humankind, and which occurs the moment when the plane of Earth’s equator passes through the centre of the Sun’s disk.
