Topic: SHUKRAYAAN MISSION
Important for Subject: Science and Technology
A space science program recently stated there was a possibility that Indian Space Research Organisation has not yet receiving acceptance from authorities from Indian Government for its Venus mission, and that the mission may in the end be delayed until 2031..
About Shukrayaan-1
• It's also known as it the Venus Mission.
• Shukrayaan I mission will be an orbiter Shukrayaan I mission will be an orbiter mission.
• Its current scientific payloads include a high-resolution synthetic aperture radar, as well as ground-penetrating radar.
• The spacecraft is expected to examine the volcanic and geological activity of Venus emission on the ground and in the air, the speed of wind, cloud cover and other characteristics of the planet due to circular orbit.
• Launch windows that are optimally positioned between Earth towards Venus occur at least once in 19 consecutive months.
Important details about Venus
• Venus is sometimes referred to as "Earth's twin" because of their dimensions and shape, however Venus is extremely hot on the surface and a toxic, dense atmosphere.
• It spins extremely slowly around its axis. One day on Venus is more than 243 Earth days.
• The dense atmosphere of Venus holds heat and creates the greenhouse effect that is sweeping across the planet - which makes it the hottest planet in the solar system.
• Phosphine is a potential indicator of microbial activity was observed in the cloud of Venus.
• As opposed to other planets in the solar system Venus rotates counter clockwise around its axis.
• Other Venus Mission
VERITAS:
• NASA's VERITAS also known as Venus Emissivity, Radio Science, In SAR, Topography, and Spectroscopy will be one of the first NASA spacecraft to study Venus since the 1990s.
• The spacecraft is scheduled to launch before the end of the end of December 2027. It will travel around Venus collecting data to discover how the routes between Venus as well as Earth diverged, as well as how Venus has lost its ability to be a viable world.
• VERITAS is the very first NASA spacecraft to study Venus, Earth's twin planet Venus in the late 1990s. The spacecraft will unravel details of the habitable planet on Venus and collect information to discover how the routes that led to Venus as well as Earth diverged.
DAVINCI:
• NASA's DAVINCI mission is set to begin in the latter half of 2020s. After exploring the uppermost part of Venus's atmosphere DAVINCI will launch probes onto the surface. In its one-hour descent the probe will make thousands of measurements and take high-quality images of Venus's surface.
• The probe might not make it through the landing however, if it survives it can give you a few minutes of extra research.
EnVision:
• The European Space Agencyhas chosen En Vision to carry out detailed observations of Venus. As a major collaborator in the project NASA will provide its Synthetic Aperture Radar, also known as Ven SAR which will make high-resolution measurements of Venus' surface characteristics.
The previous missions of Venus
1. Magellan – NASA mission, 1994.
2. Venus Express- European mission
3. Akatsuki- Japanese mission
