What is the mission of Shukrayaan-Venus mission I?
Shukrayaan I, the Venus mission of the Indian Space Research Organization (ISRO).
The launch of ISRO’s Venus mission was scheduled for Early 2024.
Other Countries’s Shukrayaan-Venus mission
The Shukrayaan-Venus mission of the European and American space agencies, VERITAS and EnVision, respectively, are scheduled for launch in 2031; China’s mission is anticipated to launch in 2026 or 2027.
Why Is There a Delay in Indain Shukrayaan-Venus mission?
The epidemic caused ISRO to reschedule the launch of Shukrayaan-Venus mission I from early 2024 to mid 2024.
Commercial launch obligations and manufacturing delays have also impacted other ISRO projects, such as Aditya L1 and Chandrayaan III.
There is one ideal window for launching from Earth to Venus once every 19 months or so. Because of this, ISRO has “backup” launch dates in 2026 and 2028 in case it loses out on the 2024 window.
However, there are even more ideal periods that occur every eight years and significantly lower the quantity of fuel needed for liftoff.
Right now, experts rate the 2031 period as excellent.
The project is also “awaiting official authorization and funding,” all of which are prerequisites for spacecraft testing and construction.
Technology Regarding of Shukrayaan-Venus mission:
Shukrayan As an Orbiter Mission, I shall be. Currently, it carries a ground-penetrating radar and a high-resolution Synthetic Aperture Radar (SAR) as research payloads.
Venus’s surface would be analyzed by SAR despite the planet’s surrounding clouds, which reduce vision.
This hints at a technique for generating high-quality images.
The radar is so precise that it can pick up data day or night and in any weather condition, even through clouds and darkness.
From an elliptical orbit, the mission is anticipated to investigate Venus’s geological and volcanic activities, ground-based emissions, wind speed, cloud cover, and other planetary features.
According to ISRO, Shukrayaan-Venus mission-I will be launched on either GSLV Mk II or GSLV Mk III, with the latter being able to carry additional fuel or instruments.
Objectives of Shukrayaan-Venus mission
The investigation of shallow subsurface stratigraphy and surface processes is the main goal.
There has never before been any subsurface observation of Venus.
Geological study of rock strata and layering is known as stratigraphy.
investigation of the atmosphere’s dynamics, chemistry, and structure.
Studying the Interaction Between Solar Wind and the Ionosphere of Venus.
Significance:
Understanding the conditions on Earth-sized exoplanets (planets that orbit stars other than our sun) and how Earth-like planets grow would be helpful.
It is a warning about how drastically a planet’s climate might change and will aid in the modelling of Earth’s climate.

Describe Venus
Venus has the name of the Roman goddess of beauty and love.
Based on size and mass, it is the sixth planet in the solar system and the second planet from the Sun.
After the Moon, it is the second-brightest natural object in the night sky.
Two planets in our solar system rotate on their axes in a clockwise direction: Venus and Uranus.
Due to the strong greenhouse effect caused by the high concentration of carbon dioxide on the planet, it is the hottest planet in the solar system.
Venus has days that are longer than years.
Venus takes more time to complete a single rotation on its axis than it does to complete a full orbit around the Sun.
With only 224.7 Earth days needed to complete one orbit of the Sun, that is 243 Earth days to rotate once, the longest rotation of any planet in the Solar System.
Due to the similarities between their masses, sizes, densities, and relative positions within the solar system, Venus and Earth have been referred to as each other’s “twins.”
At its closest point, Venus is the closest planet to Earth aside from the Moon, with no other planet approaching Earth more closely than Venus.
The atmospheric pressure of Venus is ninety times that of Earth.
