Emirates Mars mission “HOPE Probe” Here's what you need to know!

-
The first Arab interplanetary mission. It will be the first probe to provide a complete dynamic picture of the Martian atmosphere. This mission is completely managed by the Emirati team of scientists and engineers.

The main objective of this mission is to produce a global picture of the Martian atmosphere. It will be the first holistic study of mars. As of now, we know there is exotic weather exist on mars of massive dust storm just like on earth but the dust storm on earth are more brief and localized. But on mars, the dust storm can cover the mars for months. There is water on Mars but only in the form of vapor and ice. Water can’t exist on Mars in the form of liquid because the atmosphere of mars became too thin. The oxygen and hydrogen of the Martian surface is being lost in space.     

    This Mars mission will make us understand the following points  

1)    To understand climate dynamics and the global weather map through characterizing the lower atmosphere of Mars.

2)    To explain how the weather changes the escape of hydrogen and oxygen.

3)    To understand the structure and variability of hydrogen and oxygen in the upper atmosphere as well as identifying why mars are losing them into space

In every two years mars and earth align very close to each other in a line. This is the perfect time for launch with less energy and time. The rocket will be launched from Tanegashima space center, Japan. The rocket needs 40,000 km/hour speed to get out of Earth's gravity. When the first stage rocket boosters get separated. The second stage will accelerate the spacecraft to 100000 km/hour. Then the spacecraft will separate from the launch vehicle and it will unfold its solar panels and points towards the sun to charge batteries  

The orbiter is powered by batteries, charged by the 600-watt solar panels. the spacecraft Weight about 1,350kg, 1.85m antenna for communication. The dimension of the spacecraft is 3m×7.9m with solar panels open.

Further journey will be controlled by the smart onboard computers and sensors because the signal can take more than 40 min to transmit from mars to earth and vice versa.

The spacecraft will figure out its location in deep space with a star tracker to navigate using patterns of the constellation. This is similar to the way our ancestors used to find roots in deserts and at sea. The journey is about 7 months. And it will arrive on the 2021,50th anniversary of UAE. As the spacecraft reaches near mars it will use onboard thrusters as a brake to slow down to a speed of 14,000 km/hours to enter mars atmosphere.

This is going to be the most crucial part of the mission because these steps need to be taken by the onboard computers and sensors.

The data received by the probe will be freely shared with more than 200 universities and research institutes. This makes this mission more important for every country.

Aim:-  To determine the value of Stefan's constant. Apparatus:-  Black body radiation unit, Ammeter, Voltmeter, connecting wires, DC source. Theory:-  Stefan's constant: A physical constant denoted by  σ , is the constant of proportionality in the Stefan's-Boltzmann law- the total intensity radiated over all wavelength increases as the temperature increases Procedure:- 1) The electrical connections are made as shown in the circuit diagram. 2) Copper black body radiator is preheated to  30 0 C   by setting maximum voltage in the power supply 3)after the temperature indicator indicates a temperature of about    30 0 C , the voltage is reduced to some value  4) increase the voltage in steps of 0.2 V and note down the current, hence calculate power l. 5) Determine the value of Stefan's constan t. Observations:-  Room temperature t o =t+273=......of 2) surface area of the black body  A=4π r 2  = .........m square Calculation  σ  = P/ AT 4 Results:- 1)Stefan's constant st

Aim:-  To draw the frequency response of Pre-emphasis & De-emphasis networks. Introduction:- Educational trainer a useful kit for the demonstration of Pre-emphasis & De-emphasis at different time constants & plot the graph of the frequency response of Pre-emphasis and De-emphasis networks. The kit consists of 200 Hz-20 kHz audio oscillator 70µ sec & 50µ sec De-emphasis networks.  Pre-Emphasis Circuit Diagram:- DE-Emphasis Circuit Diagram:- Theory:- Pre-emphasis refers to boosting the relative amplitudes of the modulating voltage for higher audio frequencies from 2 to approximately 15 kHz . De-emphasis means attenuating those frequencies by the amount by which they are boosted.  However, Pre-emphasis is done at the transmitter and De-emphasis is done in the receiver. The purpose is to improve the signal-to-noise ratio for FM reception. A time constant of 75µ sec is specified in the RC or L/Z network for Pre-emphasis and De-emphasis. Tabular column:- Pre-Empha
