Menca isro

Hello sir, I am Suraj. I am from Bangalore. I want you to help me by giving me some information about the Mars Exospheric Neutral Composition Analyser (MENCA) payload features of Indian Space Research Organisation (ISRO). Can you help me?

Indian Space Research Organisation (ISRO) is the space agency of the Indian government.
It was formed in the year 1969.
It's headquarter is located in Bengaluru, Karnataka, India.
It is managed by the Department of Space, which reports to the Prime Minister of India.

As you have asked about the Mars Exospheric Neutral Composition Analyser (MENCA) payload features, I am giving you information about it, check below for the details

MENCA is a quadruple mass spectrometer capable of analysing the neutral composition in the range of 1 to 300 amu with unit mass resolution.
The heritage of this payload is from Chandra’s Altitudinal Composition Explorer (CHANCE) payload aboard the Moon Impact Probe (MIP) in Chandrayan-1 mission.
The instrument is operated at different mass scan rates and different bias voltages of the CEM detector in order to meet required scientific objectives.
MENCA is also equipped with a Bayard-Alpert Gauge to measure the total pressure.

Functional specifications of MENCA

Mass range
1 to 300 amu (programmable) with 1 amu resolution

Sensors
Quadrupole Mass Analyser for relative abundance measurement and Bayard-Alpert Gauge for total pressure measurement

Detectors
Channel Electron Multiplier, Faraday Cup
