NASA releases audio from Mars, video of Perseverance landing

    7

    Washington, Feb 23 | NASA has released a new video from its Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on February 18.

    A microphone on the rover also has provided the first audio recording of sounds from Mars.

    About 10 seconds into the 60-second recording, a Martian breeze is audible for a few seconds, as are mechanical sounds of the rover operating on the surface.

    From the moment of parachute inflation, the camera system covers the entirety of the descent process, showing some of the rover’s intense ride to Mars’ Jezero Crater.

    “For those who wonder how you land on Mars – or why it is so difficult – or how cool it would be to do so – you need look no further,” Acting NASA Administrator Steve Jurczyk said in a statement.

    The world’s most intimate view of a Mars landing begins about 230 seconds after the spacecraft entered the Red Planet’s upper atmosphere at 20,100 e kilometre per hour. The video opens in black, with the camera lens still covered within the parachute compartment.

    Within less than a second, the spacecraft’s parachute deploys and transforms from a compressed 46-by-66 centimetre cylinder of nylon, Technora, and Kevlar into a fully inflated 21.5-meter-wide canopy — the largest ever sent to Mars.

    The tens of thousands of pounds of force that the parachute generates in such a short period stresses both the parachute and the vehicle.

    “Now we finally have a front-row view to what we call ‘the seven minutes of terror’ while landing on Mars,” said Michael Watkins, Director of NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission for the agency.

    “From the explosive opening of the parachute to the landing rockets’ plume sending dust and debris flying at touchdown, it’s absolutely awe-inspiring.”

    The video also captures the heat shield dropping away after protecting Perseverance from scorching temperatures during its entry into the Martian atmosphere.

    The downward view from the rover sways gently like a pendulum as the descent stage, with Perseverance attached, hangs from the back shell and parachute.

    The Martian landscape quickly pitches as the descent stage – the rover’s free-flying “jetpack,” which decelerates using rocket engines and then lowers the rover on cables to the surface — breaks free, its eight thrusters engaging to put distance between it and the now-discarded back shell and the parachute.

    Then, 80 seconds and 2,130 metres later, the cameras capture the descent stage performing the sky crane maneuver over the landing site — the plume of its rocket engines kicking up dust and small rocks that have likely been in place for billions of years.

    The footage ends with Perseverance’s aluminium wheels making contact with the surface at 2.6 kph, and then pyrotechnically fired blades sever the cables connecting it to the still-hovering descent stage.

    The descent stage then climbs and accelerates away in the preplanned flyaway manoeuvre.

    Five commercial off-the-shelf cameras located on three different spacecraft components collected the imagery, NASA said on Monday.

    A key objective of Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life.

    Does MBA really help in getting a better job offer ?

    Does MBA really help in getting a better job offer ?

    Most students pursuing an MBA come with the sole objective of having a decent job offer or a promotion in the existing job soon after completion of the MBA. And most of them take loans to pursue this career dream. According to a recent survey by education portal Campusutra.com  74% MBA 2022-24 aspirants said they would opt for education loans.

    There are exceptional cases like those seeking master’s degree or may have a family business to take care of or an entrepreneurial venture in mind. But the exception cases are barely 1%. For the rest 99%, a management degree is a ticket to a dream job through campus placements or leap towards career enhancements. Stakes are high as many of them quit their jobs which essentially means loss of 2 years of income, apprehension and uncertainty of the job market. On top of that, the pressure to pay back the education loans. Hence the returns have to be high. There is more than just the management degree. Colleges need to ensure that they offer quality management education which enables them to be prepared for not just the demands of recruiters and for a decent job but also to sustain and achieve, all along their career path.

    • So, what exactly are the B Schools doing to prepare their students for the job market and make them industry ready ?
    •  Are B schools ready to deliver and prepare the future business leaders to cope up with the disrupted market ?  

    These are the two key questions every MBA aspirant needs to ask, check and validate before filling the MBA application forms of management institutes. And worth mentioning that these application forms do not come cheap. An MBA aspirant who may have shortlisted 5 B Schools to apply for, may end up spending Rs 10,000.00 to Rs 15,000.00 just buying MBA / PGDM application forms.

    While internship and placements data of some management institutes clearly indicates that recruiters today have specific demands. The skill sets looked for are job centric and industry oriented. MBA schools which have adopted new models of delivery and technology, redesigned their courses, built an effective evaluation process and prepared the students to cope with the dynamic business scenario, have done great with campus placements despite the economic slow down.

    However, the skill set being looked for by a consulting company like Deloitte or KPMG may be quite different from FMCG or a manufacturing sector. Institutes need to acknowledge this fact and act accordingly.

    • Management institutes should ensure that students are intellectually engaged, self motivated and adapt to changes fast. In one word ‘VUCA ready’.
    • B Schools should encourage students to participate in national and international competitive events, simulations of business scenarios.
    • Institutes should have the right mix of faculty members with industry exposure and pure academics.

    The placement records of 2021 across top management institutes indicated the fact that recruitment is happening, skilled talent is in demand and certain management institutions continued to attract recruiters even in the middle of an ongoing crisis.

    It is time, all management institutes rise to the occasion, understand market realities and identify areas of improvement at both ends – students and faculty.

    After all, the stakes are high at both ends. B Schools taking corrective measures will stay while those which are lagging will end up shutting down.
