Download this full article in PDF

Congratulations to ISRO for Successful Operation in Mars Orbit (Mangalyaan)

Introduction:

     Mangalyaan is the first interplanetary mission of India to explore space beyond Earth and Moon system. India and its Mangalyaan (Mars Craft) is the world's first spacecraft to achieve success in its first attempt whereas NASA got victory in second attempt, ESA got partial success in first attempt and Russia got no success out of 19 attempts. After its successful orbital insertion, India became fourth nation to reach Mars after Russia, America and Europe. India places the first nation among Asian continent to reach Mars. After this successful victory China referred India's Mangalyaan "Pride of Asia". This article explains a brief journey of India to the Red planet and their major challenge. This article is specially dedicated to Mars Orbiter Mission (Mangalyaan) in memory of four year completion of successful operation in Mars orbit from 24 September 2014 to 24 September 2018.

Highlights:

• Exploration of Mars around Four years in operation around Mars
• Major challenges and attempts made behind Mangalyaan to maintain active state
• Achievement and Honor of Mars Orbiter Mission
• Future vision of ISRO and India towards Mars and Interplanetary Mission

Mission Overview:

     Mangalyaan is an active spacecraft orbiting and investigating Mars since 24-Sep-2014. India became the fourth nation to reach Mars after the successful launch of Polar Satellite Launch Vehicle (PSLV-XL) on 05 November 2013. MOM was launched from first launch pad Satish Dhawan Space Center located near Sriharikotta range in Andhra Pradesh. It was placed in orbit during October-2013 launch window.

     MOM is a "Technology demonstrator probe" intended for future advancement of design and planning for interplanetary mission. It carried five instruments for surface topography studies. This spacecraft is being monitored by (ISTRAC) ISRO's Telemetry, Tracking and Command Network located at Bangalore with aid from India Deep Space Network antenna and additional support from NASA Deep Space Network.

History and Origin of Spacecraft:

     India have been interestingly taking part in space exploration since 1970s. Its first science mission was Chandrayaan-1 mission to the Moon in October 2008 which ultimately created history by finding water on the Lunar Surface. After the successful achievement of Chandrayaan, India's vision towards Mars was first publicly announced on 23 November 2008 by ISRO's chairman Dr. Madhavan Nair. Following the announcement design and feasibility begin in 2010 by Indian Institute of Space Science and Technology in Trivandrum. Prime minister of India Dr.Manmohan Singh approved the Mangalyaan project and accepted for funding for whole mission design and study. Based on the economic prospect, ISRO completed the whole mission within 450 crore approximately.

     On 05 August 2013, assembly of Polar Satellite Launch Vehicle (PSLV-XL or PSLV-C25). After the completion of spacecraft designs, it was shipped to Sriharikotta SHAR for the integration with PSLV launch vehicle. The design and integration was completed within 15 months of record. Following this NASA approved to provide communication support from NASA Deep space network during black out phase on 05 October 2013. After this stage, MOM set to fly into cosmos on 05 November 2013 setting proud to the Indian nation and inspiring  millions of space enthusiastic students.

Launch:

     Mangalyaan was officially scheduled to launch in 28th October 2013. But, the launch was postponed to 05th November 2013 due to the delay in ISRO's spacecraft tracking ships to take positions in the Pacific Ocean. This happened due to the bad weather in Ocean. Finally, MOM was lifted-off from Satish Dhawan Space Center at SHAR range on 05 November 2013 at 09:08 UTC. It was aimed to launch with Geosynchronous Satellite Launch vehicle, but due to continuous failure of two launches in 2010, it was switched to launch by PSLV.

Launch Challenges:

     PSLV-XL opted for launch is not powerful enough to place Mangalyaan in trans-Mars trajectory. Despite this concerns, ISRO placed MOM in high elliptical orbit around Earth and used its powerful thrusters over multiple perigee burns to place itself on a trans-Mars trajectory towards Mars. After the successful launch antenna and solar panels were successfully deployed for continuous active communication between Earth and ISRO command center. Following this operation, progressive checking of spacecraft system were also succeeded.

Trans-Mars Injection and Mars Orbital Insertion:

       After seven orbital raising maneuver burns, Mangalyaan was finally placed in Trans-Mars injection on 30 November 2013 at 19:19 UTC.After that a 23-minute engine firing was initiated to move MOM away from earth towards Mars. After travelling 780,000,000 kilometers of distance, it was successfully inserted into Mars orbit on 24 September 2014 at 02:11:46 UTC.During the travel four trajectory correction were made to correct path.

Spacecraft Design:

     The spacecraft design was similar to I-Ik structure of Chandrayaan-1 moon probe with some upgradation and modification. The spacecraft is designed with Aluminum and composite fibre reinforced with plastic sandwich construction . Power was afforded by 7.56 sq.m area of solar panels generating 840 watts of power in Mars Orbit. This energy is stored in 36 Ah Lithium-ion Battery.

     For orbital raising maneuver and orbital insertion into Mars orbit was powered by 440 newtons of liquid fuel engine. it also has eight 22 newton thrusters for attitude control. Its propellant mass is about 852 kg and the total mass of the spacecraft is 1337.2 kg.

Scientific Instruments:

1. LAP - Lyman Alpha Photometer (1.97 kg)
2. MSM - Methane Sensor for Mars (2.94 kg)
3. MENCA - Mars Exospheric Neutral Composition Analyzer (3.56kg)
4. TIS - Thermal Infrared Imaging Spectrometer (3.20 kg)
5. MCC - Mars Colour Camera (1.27 kg)

     LAP and MSM were used for atmospheric studies; MENCA was used for particle environment studies; TIS and MCC were used for surface imaging studies.

Scientific Objective of the Mission:

• Primary - Technology demonstration for the purpose of designing, planning, management and operations for interplanetary mission.
• Secondary - Explore Mars surface, morphology, mineralogy and Martian atmosphere using indigenous scientific instruments.
• Tertiary - Explore the Mars surface features like topography, mineralogy, atmosphere, Methane and CO2 detection using remote sensing detection, dynamics of upper atmosphere, effect of solar wind and radiation, escape of volatile atmosphere to outer space.

Pursuing Challenges: 

     Inspite of having low powerful launch vehicle “MOM” reached Mars by injecting itself in Trans-Mars trajectory towards Mars using continuous orbital maneuvering propulsion.  Survived in Black out phase when Mars lacked sunlight (It lost most of its fuel during this concern and moved away from blackout for power production).  Loss of capability for Methane detection of MCC (Mars Color Camera) made scientists to switch for albedo mapping applications.  This mission is planned for 6 months, but it survived more than 4 years and expected to continue its observations till 2020s.

Honors and Awards:

• Upon successful orbital insertion on 24 September 2013. NASA and their scientist congratulated ISRO and Mars scientist including whole team.   
• Google also celebrated the one-month successful operation of Mangalyaan around Mars.
• In 2014,China referred India's MOM as "Pride of Asia".
• MOM and theirs scientists won "US-National Space Society's 2015 Space Pioneer Award" in science and engineering category of which NSS stated "The award was given for successfully executing Mars Mission in its first attempt".
• One of the image of Mangalyaan's spacecraft is printed in Rupee 2000 currency note of India

Parker Solar Probe  Image Credit: NASA

      National Aeronautics and Space Administration's Parker Solar Probe mission will change the perspective view and understanding of the Sun, where major changing condition happens in outer sphere of sun propagate into solar system affecting our earth and planetary systems. It will be the first spacecraft to travel too closer to the Sun's atmosphere after MESSENGER spacecraft facing enormous heat and radiation condition. It will provide a closer view of nearest star to the observers.

     Parker Solar Probe is estimated to unlock all the mysteries of Sun, in order to achieve this intent, it will use Venus gravity assist to gradually travel near to the sun during seven days of flyby around Venus. It is estimated approach to sun is about 3.8 million miles ( within the orbit of Mercury) and seven times closer than any spacecraft has ever attempted.

     Parker Solar Probe was launched from Cape Canaveral Air Force station on 12th August 2018 strapped with Delta IV-Heavy class launch vehicles. Now the spacecraft is in the trajectory phase to Sun. It will fly first into the outer part of the sun (Corona) and will start its experiments and imaging. The experimental result will help us to expand our knowledge about the origin and evolution of solar wind in sun's atmosphere. The winds affects the technological spacecrafts around earth and damage to life systems on Earth.

     Parker Solar Probe will perform extreme level scientific investigations and studies in a hazardous condition around the region where there is extreme heat and radiation. The spacecraft will fly close to the sun by crossing extreme sun's particles. Instruments will be protected from heat by a 4.5 inch thick carbon wall to maintain stable temperature and to perform investigations.

    Parker Solar Probe is a part of NASA's Living with a Star exploration  program and its operations were managed by Goddard Spaceflight Center in Greenbelt. The John Hopkins University Applied Physics Laboratory in Laurel is responsible for design and building of spacecraft and mission operation.

Discovery of Sub-Saturn Exoplanet around a Star

Sub-Saturn like Planet Discovery, India (PARAS Spectrograph).

Flash points:

• Indian discovery of exoplanet named K2-236b.
• Discovered by team of Dr.Abijit Chakraborthy.
• Surrounds around EPIC 211945201 Star.
• Precise measurements was made by PARAS Spectrograph.
• Observation were made in Gurusikhar Observatory, Mount Abu, India.
• It's mass is about 27-times mass of Earth.
• It lies about 600 light years away from Earth
• Surface temperature of the planet is about 600 degree Celsius.
• Period of Revolution around star 19.5 days.
• Period of discovery and confirmation 420 days (1.5 Years).
• The Research article can be found at doi:10.3847/1538-3881/aac436

 Scientific Facts:

    The scientific team led by professor Abijit Chakraborthy of Ahmedabad Physical Research Laboratory discovered a sub-Saturn or super-Neptune size about 27 times the mass of Earth. The planet moves around the star in every 19.5 days. It is about 600 light years away from our earth. The discovery was made with a new kind of rare spectrograph in Asia called PARAS ( Physical Research Laboratory Advanced Radial Velocity Abu-Sky Search) which is about 1.2 m telescope in PRL's Gurusikhar Observatory located in Mount Abu, India.

      The surface temperature of the planet is about 600 degree Celsius measured by very sensitive instruments. The name of  the hot-star is EPIC 211945201 or K2-236. Initially, the source was found to be a planetary candidate from NASA K2 photometry, because it was transisting and lies between the star and the observer on the earth as it goes around the star and blocks tiny amount of light to reach earth.

     Using the spectrograph, its radii was about 6 times the Earth radii. The K2 photometric data was not sufficient to confirm the planetary nature of the planet. Therefore, independent measurement of the mass of the body was necessary for the discovery, which was made by PARAS spectrograph.

Accidental discovery of 12 Jupiter's new moons

12 New moons of Jupiter discovered

Team of astronomers from Hawaii and Arizona has reported the discovery of 12 moons around Jupiter in addition to 67 moons which were discovered earlier. After this majestic discovery the total count of the Jupiter's moon reached to 79 which is most for any other planet./

The discovery of this moons were not planned but they were accidentally discovered while looking for the objects on the fringes of the solar system. In this report, astronomers confirmed that two were discovered earlier and 10 more were discovered on Tuesday. One of these moon called oddball as named by the astronomers due to the unusual orbit around the Jupiter.

The newly identified moons were too small ranges from 1 km to 2 km. But the Jupiter is a home to the largest moon in the solar system Ganymede having diameter about 5,268 km. These team were led by astronomer Scott Sheppard of the Carnegie Institution for Science in Washington who identified twelve small Jovian moons.

Researcher conclude that these moons were formed in the earlier stage of formation of the solar system but they were probably captured by the Jupiter's strong gravitational pull. Researcher thinks that, these moons may be intermediate between rocky asteroids and icy moons. Because they are probably half ice and half rock.

Valetudo is named for the odd moon which have unusual orbit around Jupiter. It was named after the Roman god Jupiter's great-granddaughter - the goddess of health and hygiene. It spins normal like other moons but it sometimes spins in a wrong way. It have probability of getting collided with other objects. It may have collided with many objects as predicted by Scott Sheppard. From this discovery he concludes that, other planets may have undiscovered moons.

Crew Escape System:

Crew Escape System-India-Technology Demonstrator

     India had planned to carry out manned mission by 2018, but due to some obstruction in financial condition. It has achieved a major technology demonstration on 05-July-2018. The first series of tests to qualify Crew Escape System, which is critical technological relevant for human spaceflight. The crew escape system is an emergency escape designed to quickly pull astronauts along with crew module away from launch vehicle during emergency launch abort. The foremost test (Pad Abort Test) demonstrated the safe recovery of crew module in case of exigency in launch pad from Sriharikotta Rocket Launch Pad.

     After a smooth countdown of 5 hours, the Crew Escape System along with crew module with mass of 12.6 tonnes, lifted off at 07:00 AM Indian Standard Time at the opening of the launch window from Satish Dhawan Space Centre, Sriharikota on 05-07-2018. The test was over in 259 seconds, during the Crew Escape System roared towards the sky and landed in Bay of Bengal using main parachutes about 2.9 kilometers away from Sriharikota.

    After the launch, the Crew Escape System reached a height of 2.7 km using specially designed seven solid rocket motors. During the course of launch, nearly 300 sensors recorded various mission performance parameters. After the landing, three boats were used to recover the Crew module from Bay of Bengal.

    Indians hope that this type of Crew Capsules will be helpful in manned mission for the exploration of Moon and they may extend their exploration to Mars after subsequent mission of Mangalyaan-2. This Crew Escape System is complete indigenous technology designed and developed in India by various scientists and engineers. It is aimed that India will join the major countries to have the capabilities of launching crews to space after future successful mission. First man in space Dr.Rakesh Sharma brought proud to the Indian nation reaching the space from Russian manned mission. But, soon we will have astronauts in space, which will be launched from Indian land with its own indigenous launch vehicle.

Discovery of Saturn like planet around a star | India

Date: 22-June-2018

Discovery of new exoplanet around a star:

Discovery of Indian Exoplanet

     A team of researchers and engineers under professor. Abhijit Chakraborthy from Physical Research Laboratory (Ahmedabad), have discovered a planet which size lies between sub-Saturn and Super-Neptune. Its mass is about 27 times of Earth around a sun like star. The planet was named as EPIC-211945201b or K2-236b.

The work regarding the discovery and measurement has appeared in the Astronomical Journal of the American Astronomical Society and the article was published by IOP Publishing house.

The discovery was made by measuring the mass and size of the planet by using the indigenously developed PRL Advance Radial-velocity Abu-sky Search (PARAS) spectrograph integrated with 1.2m diameter telescope located at Gurushikhar Observatory in Mount Abu, India. There are 23 such planetary systems are known to this date with masses between 10 to 70 Earth mass and size of 4 to 8 Earth radii. This discovery is very important to understand the formation of planets and planetary systems around sun like star.

With this discovery of EPIC-211945201b, India has joined a handful of countries, which have discovered planets around stars beyond our solar system.

About PARAS:

     PARAS is the first kind of spectrograph in Asia, which can measure the mass of a planet going around a star. Rare spectrograph were found all over the world which can measure such precise measurements.

Organic Molecules in Enceladus

     Data from earlier Cassini mission spacecraft has found complex organic molecules coming out of Saturn's Icy moon Enceladus. It strengthens the idea of existence of water and hosts good condition for life.

Scientists revealed that complex organic material get mixed with hot hydro-thermal water and released into space in the form of water vapor and ice grains. These results were discovered by a team led by Frank Postberg and Nozair Khawaja from the University of Heidelberg.

On Enceladus, bubbles of gas, rising through miles of ocean, could bring up organic material from depths, where they could form a thin film floating on the ocean surface and in cracks of vents, in the interior of the moon, beneath its icy shell.

After rising near the top of the ocean, the bubbles may burst or otherwise disperse the organics, where they were detected by Cassini.

Continuing studies of Cassini data will help us unravel the mysteries of this intriguing ocean world,” said Cassini Project Scientist Linda Spilker of NASA’s Jet Propulsion Laboratory, Pasadena, California.
