- NASA is inviting names from all over the world
- Now you can have your name placed on a microchip
- This chip would be in NASA’s historic Parker Solar Probe mission
NASA is inviting people around the world to submit their names online to be placed on a microchip aboard NASA’s historic Parker Solar Probe mission, to be launched this summer.
The mission will travel through the Sun’s atmosphere, facing brutal heat and radiation conditions — and your name will go along for the ride. The submissions of names will be accepted until April 27, the US space agency said in a statement on Thursday.
“This probe will journey to a region humanity has never explored before. This mission will answer questions scientists have sought to uncover for more than six decades,” said Thomas Zurbuchen, Associate Administrator for Science Mission Directorate at NASA.
The spacecraft — about the size of a small car — will travel directly into the Sun’s atmosphere about four million miles from the star’s surface. The primary goals for the mission are to trace how energy and heat move through the solar corona and to explore what accelerates the solar wind as well as solar energetic particles.
To perform the investigations, the spacecraft and instruments will be protected from the Sun’s heat by a 4.5-inch-thick carbon-composite shield. The state-of-the-art heat shield will keep the four instrument suites designed to study magnetic fields, plasma and energetic particles, and image the solar wind at room temperature. In May 2017, NASA renamed the spacecraft from the Solar Probe Plus to the Parker Solar Probe in honour of astrophysicist Eugene Parker. IANS

ॐ त्रिकालसन्ध्यानुष्ठितभूम्यै नमः
(Ṫrikāla: Three periods of the day; Sandhya: Obeisance to Sun god; Anuṣthiṫa: Practice, performance)
The word sandhya refers to those times, when night passes into day and day passes into night. They are dawn and dusk. The ritual of one's obeisance to God during these periods is known as sandhyāvandanam. Doing the ritual thrice at dawn (prātah sandhyā), at midday when the sun is right above our head (madhyāhna sandhyā); and dusk (sāyantrah sandhyā) is known as trikāla.
A person who has undergone the upanayana ceremony, as also house-holders (except the working class), are expected to perform this sandhyā ritual three times a day, as a sacred duty. These three rituals have many steps in common. However, in practice, only the first and the last have survived. The scriptures have provided for this modification.
After taking a bath and wearing the traditional religious dress (dhoṫi and chadar or uttarīya) one should apply the religious marks on the forehead (like the vibhūti or the ūrdhva puṇḍra as per one's family traditions), and sit on the seat (kept aside and used only for such religious purposes). Though there are differences in the procedure and the various steps to be followed, the six steps common to all and the detailed procedure has to be learnt from the family priest or the elders in the family.
These six steps are: 1) Āchamanam- is the ceremonial sipping of water from the right hand cupped in the shape of the ear of a cow (gokarṇam) to the appropriate mantras. This āchamanam is a general purification act that precedes every religious undertaking. 2) Prāṇāyāmam- is the control of the prāṇic energy through the regulation of the breathing process as detailed in the works of yoga. Prāṇayāmam helps in the control of the mind also. 3) Mārjanam- is literally means cleansing or purifying. It consists of sprinkling water on specified parts of the body with a mantra. This process will make the body ceremonially pure and fit the ritualistic act. 4) Arghyapradāna-is the offering of water taken in the two hands cupped together, by repeating the Gāyatrī mantra and addressing the Sun-god. This is just to show our gratitude to the Sun-god who is our primary life-support. 5) Gāyatrī japa-is for the goddess Gāyatrī within the orb of the sun. 6) Sūryopasṭhāna- is repeating the prayer addressed to the deity Gāyatrī in the standing posture, facing the sun. This is the last rite of bidding farewell to the goddess after having invoked her and satiated her through japa.
Hence, our land which worships the Sun-god who is our primary life-support, three times a day is known to be 'Trikālasandhyāvandānuṣthiṫa Bhūmi'.
