 Economy 
Consumer inflation 
  
 | 
 India’s retail inflation slid below the 6% mark for the first time in 2023, to touch 5.66% in March 2023. 
- The drop was aided by base effects, as the same month had recorded an almost 7% price rise last year.
 
 
About Inflation: 
- It is the rate at which the general level of prices for goods and services is rising and, consequently, the purchasing power of currency is falling.
 
- The most commonly used inflation indexes are the Consumer Price Index (CPI) and the Wholesale Price Index (WPI).
 
- India’s retail inflation is measured by the Consumer Price Index (CPI).
 
 
About Consumer Price Index (CPI): 
- It is an index measuring retail inflation in the economy by collecting the change in prices of most common goods and services used by consumers.
 
- The CPI is used to calculate the inflation levels in an economy.
 
- In India, there are four consumer price index numbers, which are calculated, and these are as follows:
- CPI for Industrial Workers (IW)
 
- CPI for Agricultural Labourers (AL)
 
- CPI for Rural Labourers (RL) and
 
- CPI for Urban Non-Manual Employees (UNME).
 
 
 
- While the Ministry of Statistics and Program Implementation collects CPI (UNME) data and compiles it, the remaining three are collected by the Labour Bureau in the Ministry of Labour.
 
- The base year for CPI is 2012.

Jupiter Icy Moons Explorer (Juice) 
  
 | 
 The European Space Agency (ESA) is going to launch the Jupiter Icy Moons Explorer, or Juice, mission from its spaceport in French Guiana. 
About: 
- The Juice “will make detailed observations of the Jupiter and its three large ocean-bearing moons — Ganymede, Callisto and Europa”.
 
- It uses technologies like remote sensing, geophysical and other in situ instruments.
 
- Three moons of Jupiter possess icy crusts, which scientists believe contain oceans of liquid water underneath, making them potentially habitable.
 
- Juice will help probe these water bodies by creating detailed maps of the moons’ surfaces and enable the scientists, for the first time, to look beneath them.
 
- Although the mission will examine all three moons, the main focus will be on Ganymede, as it is the largest moon in the Solar System.
 
- Ganymede is larger than Pluto and Mercury. It is the only one to generate its own magnetic field.
 
-  Juice, which will move into Ganymede’s orbit after approximately four of arriving at Jupiter, will “use its suite of ten sophisticated instruments to understand Ganymede.
 
- Juice will also analyse the chemistry, structure, dynamics, weather, and climate of Jupiter and its ever-changing atmosphere.
