The recent reports have brought a moment of joy for the whole world as NASA’s Mars rover ‘Perseverance’ has succeeded in landing on Mars. This can be marked as a point from where the new phase of space research begins. A ray of hope which was not visible enough has been brought to light by this mission. The midnight of 18th February will be remembered as the day of light as the rover has landed at 20:25pm (GMT) on the surface of Mars. This is a moment of pride we will remember in many years to come and wish for the smooth proceedings of the mission.
ACTIVITIES THROUGHOUT CRUISE
During the cruise section of the mission (the time between launch and landing), engineers on Earth are keeping tabs on the space vehicle. Major activities throughout the cruise have included:
• Checking space vehicle health and maintenance
• Monitoring and calibrating the space vehicle and its on-board subsystems and instrument.
• Performing angle correction turns (slight spins to stay the antenna pointed toward Earth for communications and to stay the star panels pointed toward the Sun for power).
• Conducting navigation activities, like flight correction maneuvers, to see and proper the flight path before region entry.
• Preparing for entry, descent, and landing and surface operations, a method that has tests of communications, together with the communications to be used throughout EDL.

ALL ABOUT ROVER ON FEBRURY 18, 2021
Nasa’s rover Perseverance with success landed on the surface of Mars on Friday created a historic landing on Mars and thereby creating full world pride. The landing website of the crater was Jezero Crater, named once Jezero, a little municipality settled on the Veliko Plivsko Lake.
NASA ROVER: CAN DIG TO SEARCH OUT THE TRADITIONAL LIFE ON MARS
Before landing on Mars, rover have skipped past the earth, burned a courant entry, smashed into the surface, and created it down amid a fierce duster solely to spit out one fuzzy grey image before dying. Virtually fifty years, once the primary casualty at Mars, NASA is making an attempt of its hardest Martian touchdown nevertheless. The rover named Perseverance is headed on Thursday for a compact 5-mile-by-4-mile patch on the sting of associate ancient stream delta. It was stuffed with cliffs, pits, sand dunes and fields of rocks, any of that might doom the $3 billion mission. The once submerged piece of ground conjointly might hold proof of past life, all the additional reason to collect samples at this spot to come back to Earth. Ten years from now wherever there was water, there could be life. That’s why NASA desires Perseverance snooping around Jezero Crater, once home to a lake fed by a stream. Many dozen core samples – a couple of pound’s value (one-half kilogram) of rock and dirt – are going to be put aside in sealed metallic element tubes for future pickup. Scientists had needed to induce hold of Mars rocks ever since NASA’s Mariners provided the primary shut footage a time period past.
ROVER LANDING WAS THE DISTINCTIVE ONE ALL FROM NASA’S
Military headquarters confirmed that the rover landing was distinctive because it is completely on its own and no human input is needed. Laboratory quickly received knowledge from Mars satellites and also the rover itself confirmed an honest touchdown, as well as the primary pictures from Perseverance: scenes of a desolate, unclean landscape that appears dangerous to humans however packed with potential for this scientist-explorer. ” This is often thus surreal. Such a lot has been riding on this.” Perseverance continuing causation pictures from its hazard-detecting guidance cameras.
SIGNIFICANT ROLE OF PARACHUTE IN SUCCESSFUL LANDING
The parachute helps slow the craft down throughout entry, descent, and landing. It’s placed within the backshell (green canister within the model to the left). The design of the parachute is driven by “loads”. Mass area unit calculated by victimization region density, velocity, parachute drag space, and mass. The parachute is formed out of 2 sturdy, light-weight fabrics: polyester and nylon.
LAST IN THE LIST IS SAMPLE CATCHING- THE MOST IMPORTANT PROCESS
The Perseverance rover can gather samples from Martian rocks and soil victimization its drill. The rover can then store the sample cores in tubes on the Martian surface. This whole method is named “sample caching”. Mars 2020 is the primary mission to demonstrate this on Mars. It may probably pave the means for future missions that would collect the samples and come back to Earth for intensive laboratory analysis. The 3 major steps in sample handling are
Step 1: Assembling the Samples
Step 2: Sample waterproofing and Storing it
Step 3: Depositing the Samples on the Surface Storing
STORING THE SAMPLE : MAJOR PHASE
After a sample is collected, the sample tube is transferred back to the rover’s belly. There, it’s two-handed off to the little interior robotic arm and affected to review and waterproofing stations. Once the tube is hermetically sealed, nothing will enter or leave it. The tube area unit holds on within the rover belly till the team decides on the time and place to drop the samples off on the surface.
