Satellite Radio Broadcasting 2001

XM revolutionizes radio broadcasting:

Idea of Broadcasting:

      How often have you been listening to your favourite radio station in your car, only to have it slowly dwindle away as you drive out of range of the transmitter? The answer to this problem came in 2001 when a new way to receive radio is made its debut -  a national service beamed from outer space that, in return for a subscription free, offered 100 different channels, none of which would be interrupted by poor reception.

Broadcasting through Satellite:

     The Coverage, provided by two or three high-orbit satellites, came as a strong signal requiring no satellite dish, just an antenna the size of the match box. Although the broadcast could be dampened by sky scrappers or long tunnels, the signal was bolstered by transmissions from ground based towers.

XM and Sirius Initiative:

     Two companies were originally granted licenses to provide satellite radio in 1997 : XM and Sirius, with XM getting off the mark first in the US in September 2001 and the Sirius following in 2002. For the monthly subscription fee of $10 the Xm Service offered a wide choice: some channels were dedicated to specific topics such as news, sports, traffic and weather reports; music channels had no commercials and even no DJ's, and talk shows were less censored than the free terrestrial radio broadcasts.

Audience at First:

     What is more, satellite radio receivers displayed the name of each artist and songs as it played. Soon receivers were being made that could be taken out of cars and carried into the home.Initial uptake was slow. At launch it was estimated that there were only four listeners per channel, but by 2008 a total audience of over 16 million had been garnered. Despite legal wrangles over music copyright and complaints about the content of some chat shows, it seems that satellite radio is here to stay.

Twisted Galaxy

Image Information:

Image Credit  : ESA/NASA Hubble Space Telescope
Object             : IC 1727
Type                : Twisted Galaxy
Date of Image : 18 August 2017

Science Information:
     The above image taken by NASA/ESA Hubble Space Telescope is IC 1727, which is currently interacting with its near neighbour NGC 672. This pair's interactions have triggered peculiar and intriguing phenomena within both objects - most noticeably in IC 1727. The galaxy structure is visibly twisted and asymmetric, and its bright nucleus has been dragged off-center.

     In interacting galaxies such as these, astronomers often see signs of intense star formation and spot newly formed star clusters. They are thought to be caused by gravity chuming, redistributing and compacting the gas and dust. In fact astronomers have analyzed the star formation within IC 1727 and NGC 672 and discovered something interesting, observations show that simultaneous bursts of star formation occurred in both galaxies some 20 to 30 and 450 to 750 million years ago. The most likely explanation for this is that the galaxies are indeed an interacting pair, approaching each other every so often and swirling up gas and dust as they pass close by.

Florence Asteroid will pass Earth on September


     Asteroid Florence, a large near Earth asteroid will pass safely by Earth on 1st September 2017 at a distance of about 7 million kilometers. Florence is a large near earth seized asteroid which is about 4.4 kilometer in diameter in size. Diameter data was provided by NASA's Spitzer Space Telescope.


     Florence asteroid was first discovered by Schelte Bobby Bus at Siding Spring Observatory in Australia in March 1981. It is named in the honor of Florence Nightingale (1820-1910) the founder of Modern Nursing.The 2017 encounter is the closest by this asteroid since 1980 and the closest it will ever be until after 2500. Florence will brighten to ninth magnitude in late August and early september, when it will be visible in small telescopes for several nights as it moves through the constellation Piscis Austrinus, Capricornus, Aquarius and Delphinus.


     Radar has been used to observe hundreds of asteroids. When these small, natural remnants of the formation of the solar system pass relatively close to Earth, deep space radar is a powerful technique for studying their sizes, shapes, rotation, surface features and roughness, and for more precise determination of their orbital path.

Pratham Satellite


     The IIT Bombay Student Satellite Project is a landmark project taken up by IIT Bombay Students. The Objective of this project is to make IIT Bombay a respected centre for advancement in satellite and space technology that is being developed in the institute and also a method for space qualification.

Pratham is the first satellite under this project. The plan was to build a fully functional microsatellite which would then be launched by the Indian Space Research Organisation (ISRO). This is entirely a student initiative with mentorship provided by ISRO scientists and IIT Bombay Faculty.  The satellite will fit in a 30.5cmx33.5cmx46.6cmx46.6cm cube and will weigh 10.15kg excluding FE Ring.

    For the revelance of our satellite to the student community, we will be transmitting satellite data when the satellite passes over India so that any interested university with a small ground station will not only be able to detect the beacon signal fromour satellite but will also be able to measure TEC above their ground station. This is proposed to spread awareness among the student community about this exciting field. The Pratham Project presents a wonderful learning experience to the students of working on a real life multi-disciplinary complex system. A lot of importance is attached to learning, this is evident from the success criterion.


     The Ham community is very critical to the success of any satellite working in the amateur band. We are also looking forward to hearing from Hams around the world for beacon and telementry reports.

     Yinghhuo-1 was chinese spacecraft intended to visit Mars which was launched from Baikonur Cosmodrome in Kazakhastan on 8th November 2011. It was launched along with the Russian probe Phobos-Grunt which was intended to visit moon of Mars "Phobos". However due to the improper firing of propulsion. Finally both the spacecraft was lost.


  1. Plasma Package
  2. Fluxgate Magnetometer
  3. Radio - occultation Sounder
  4. Optical Imaging System

  • To study detailed about plasma environment and magnetic field
  • To Study the landscape processes on Mars
  • To conduct ionospheric occultation measurements between Yinghuo-1 and Fhobos-Grunt, focusing on the sub-solar and midnight regions
  • To Observe the Sand-Storms on the Martian surface

     Yinghuo-1 and Fobos - Grunt was launched together from Baikonur Cosmodrome on 8th November 2011. Shortly after the launch, Fobos was expected to perform two burns to depart LEO. But the burn did not take place standing in the parking orbit. 

On 17th November Chinese state declared that the Yinghuo-1 probe was lost and the Fobos - Grunt gradually began to decay. Finally on 14th January 2012, it was reported that Fobos and Yinghuo were beginning their final descent into earth's atmosphere falling at the rate of several hundred metres per hour.  The two spacecraft completed their re-entry and disintegrated over the Pacific ocean on 15th January 2012.

Cassini - End of Mission

Video Source : NASA Science Casts | Youtube | Cassini Grand Finale to its Saturn Mission


      Cassini Grand Finale is about so much more than the spacecraft's final dive into the planet Saturn. The dramatic event is the capstone of six months of daring exploration and scientific discovery.


  • The spacecraft will make detailed maps of Saturn's Gravity and Magnetic fields, revealing how the planet is arranged internally, and possibly helping to solve the irksome mystery of just how fast saturn is rotating
  • The final dives will vastly improve our knowledge of how much material is in the rings, bringing us closer to understanding their origins.
  • Cassini's particle detectors will sample icy ring particles being funneled into the atmosphere by Saturn's magnetic field
  • Its cameras will take amazing, ultra-close images of Saturn\s rings and clouds

     Cassini's final images have been sent to Earth several hours before its final dive into the atmosphere of Saturn. It will send information and data on Saturn's Atmosphere during its dive. The data will be collected from the Mass Spectrometer. It will send detailed information on atmosphere teling us about its composition until the contact is lost.
Mission Starting from its launch in 1997 to the unique Grand Finale Science of 2017, the Cassini-Huygens mission has racked up a remarkable list of achievements.


 By the year 2017 , Cassini will have spent 13 years in orbit around Saturn, following a seven-year journey from Earth. The spacecraft is running low on rocket fuel used for adjusting its course. If left unchecked, this situation would eventually prevent mission operators from controlling the course of the spacecraft.


     Two moons of Saturn, Enceladus and Titan have captured news headlines over the past decade as Cassini data revealed their potential to contain habitable - or at least Pre-biotic environments.


      In order to avoid the unlikely possibility of Cassini someday colliding with one of these moons, NASA has chosen to safely dispose of the spacecraft in the Saturn's atmosphere. This will ensure that Cassini cannot contaminate any future studies of habitability and potential life on those moons.The mission will end on 15th September 2017.

Schiaparelli Lander

Schiaparelli Lander ESA

     Schiaparelli Lander is an technology demonstrator landing module launched by European Space Agency along with ExoMars Trace Gas Orbiter. ExoMars and Schiaparelli is an joint mission between esa and Russian Space Agency (Roscosmos). It was planned to gather details on Mars atmospheric condition, existence of life and Geologic features. It was made in Italy. It was named in the honor of astronomer Giovanni Schiaparelli of 19th century.


     The Schiaparelli lander originated from ESA's aurora Programme which is a goal for human mission to space. The lander was planned by ESA and designed by Italy. Its another name was ExoMars Static Lander.

  • In search for the existence of life in past and present
  • To characterize the geological and Geochemical environment
  • To study the environment and identification of hazards for future missions
  • To investigate the planets interior and sub-surface for better understanding

     Schiaparelli Lander was launched along with ExoMars Trace gas orbiter on 14th March 2016 at 09:31 GMT. Four rockets were burned and the launch was successful reported by a signal received from the descent module at 21:29 GMT.


     On 16th October 2016, the Trace Gas Orbiter released EDM Lander, and the lander travelled at a speed of 21,000 km/hour. During its travel it spun at the rate of 2.5 Rotation Per Minute. Meridiani Planum was chosen for the landing site on Martian Surface.


      Schiaparelli lander attempted an automated landing on 19 October 2016, but the signal was unexpectedly lost a short time before the planned landing time. ESA's Mars Express and Mars Reconnaissance Orbiter and MAVEN continued listening for the lander signal to no avail. Lander transmitted about 600 megabytes of telementry data during its landing attempt. However the mission was failure the lander crashed due to error in the Inertial Measurement Unit.

TRAPPIST-1 is older than our solar system


     NASA had made wonderful discovery of Trappist-1 system which is the best discovery of Hubble Space Telescope and NASA. Now, if we want to know more about the existence of life beyond the solar system, we need to know the age of the star. Young stars have frequent releases of high energy radiation called flares that can zap their planets. If a new planet is born then the orbit of that planet would be unstable.On the other hand, planets orbiting older stars have survived the spate of youthful flares, but have also been exposed to the ravages of stellar radiation for a longer period.

Now NASA's Scientists have a good estimate for the age of one of the most intriguing planetary systems discovered to the date called Trappist-1 System. A system of 7 earth seized planet orbiting a star which is nearly 40 million light years away from the earth. Researchers said that new study reveals that the star is too old between 5.4 to 9.8 billion years ago.

The seven wonders of TRAPPIST-1 were discovered using Transisting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile, Spitzer Space Telescope of NASA, and other ground based telescopes.

Trappist-1 is 13.7 billion years old in age than the universe and it is like a slow-burning candle that will shine for about 900 times longer than the current age of the universe.

Fornax Dwarf Galaxy

Fornax Dwarf Galaxy in constellation of Fornax
Fornax Dwarf is an elliptical dwarf galaxy which is located in the constellation of Fornax and this galaxy was first discovered in 1938 by Harlow Shapley. He discovered it while he was in work on a project in South Africa, photograph was taken in Bruce refractor at Boyden Observatory shortly after he discovered the Sculptor Dwarf Galaxy.

This galaxy is a satellite of the Milky way and contains six most globular clusters and the largest NGC 1049 was discovered before the galaxy itself. The galaxy also receding from the Milkyway at 53 km/s. It mostly contains population II Stars.

Scientists derived a color magnitude diagram of Fornax 4, a globular cluster using the image from Hubble Space Telescope within this galaxy. Fornax globular clusters have Fornax 1,2,3 and 5 are horizontal branches. Fornax-4 is also 3 Gyr younger than other globular clusters.

Veil Nebulae & Supernova Remnant

Veil Nebulae
Image description:

     NASA's Hubble Space Telescope imaged a  massive star that exploded nearly about 8,000 years ago. This star was named as Veil Nebulae, the debris is one of the best remnants which derived its name from delicate and draped filamentary structures. The entire nebulae is about 110 light years across, covering six full moons on the sky as seen from the Earth. It is located nearly about 2,100 light years away from the Constellation Cygnus, the Swan.

About Veil Nebulae:

     The Veil nebulae has mass which is equal to the 20 times the mass of our Sun. The fast moving blast wave shown in the picture is from the ancient explosion is plowing into a wall of cool, denser interstellar gas by emitting lights. It lies at the edge pf the low density gas that was blown into space by dying star prior to its self-detonation.

This image shows the collision of blast wave and the gas dust that makes up the cavity wall. The nebulae resembles a crumpled bed sheet viewed from the side.

Color Information of Veil Nebulae:

    The Red color denotes the glow of hydrogen, green corresponds to the Sulphur, and the blue from Oxygen. The Bluish features, outlining the cavity wall appears very smooth. The red filaments arise after gas is swept into shock wave at speeds of nearly 1 million miles per hour, so fast that it could travel from Earth to the moon in 15 minutes. Astronomers are comparing these new images to the im\ges taken by Hubble in 1997. This comparison allows scientists to study how the nebulae has expanded since it was photographs over 18 years ago.

1987-A Supernova

Supernova 1987-A
Image Description:

     This Hubble Space Telescope image shows the Supernova 1987A with Large Magellanic cloud, a neighbouring galaxy to our Milkyway galaxy.

About Supernova 1987A:

     This Supernova 1987A is located at the center of the image. There is a bright ring around the central region of the exploded star which is composed of material ejected by star. The material is about 20,000 years before its demise. Gaseous clouds surround the supernova, the red colour represents the glow of hydrogen gas, which is fueling a firestorm of star birth.


     Supernova 1987A was discovered in 1987, and Hubble began observing the exploded star in the early 1990s. This latest view was taken by Hubble Wide Field Camera 3 in January 2017. The colors of the foreground and background stars were added from observations taken by Hubble Wide Field Planetary Camera 2. This supernova 1987A resides 163,000 light years away from our Earth.

Dynamic Storm in Jupiter's North

Dynamic Storm in High North of Jupiter. Image Credit : Juno / NASA
Image Description:

     NASA's active spacecraft on Jupiter (Juno) observed a dynamic storm at the northern polar region which dominates the Jovian cloudscape, courtesy of Juno Spacecraft. 


     This storm is long-lived anticyclonic oval named North North Temperate Little Red Spot 1 (NN-LRS-1), this storm has been tracking since 1993, and maybe older still. An anticyclone is a phenomenon of weather where two winds flow opposite to each other in their direction under very low pressure.It is the third largest anticyclonic oval on the planet, typically around 3,700 miles (6000 kilometers) long. The color varies from red and off-white, but this Juno cam image shows that it still has a pale reddish core within the radius of maximum wind speeds.

Image Mapped by:

     This image was mapped and processed by citizen scientist Gerald Eichstadt and Sean Doran using the data from JunoCam imager. 

Photo Details:

     The image was taken on 10 July 2017 at 6:42 PM, as the Juno Spacecraft performed its seventh close flyby of Jupiter. At the time of imaging the spacecraft was about 11,444 kilometers from the tops of the clouds of the planet at a latitude of 44.5 degrees.

Exoplanet with Glowing Water Atmosphere

Exoplanet with watered atmosphere Image Credit: NASA
Scientists have discovered strongest evidence to date for a stratosphere on a planet outside our solar system (Exoplanet). Stratosphere - layer of atmosphere in which temperature increases with higher altitudes. So our planet has warm stratospheric atmosphere and this type of atmosphere must be found in other exoplanet system also beyond solar system.

Reporting in the journal nature, NASA's Scientists used the data collected by Hubble Space Telescope to study WASP-121b, a type of exoplanet called a hot Jupiter. Its mass is 1.2 times that of Jupiter and its radius is about 1.9 times Jupiter making its puffier. Jupiter revolves our sun once in 12 years, but this WASP-121b revolves its sun once in 1.3 days. This exoplanet is very close to its star. The star's gravity would start ripping it apart. It also means that the top of the planet's atmosphere is heated about 4600 degrees Fahrenheit. The WASP-121 system is estimated to be about 900 light years from Earth -  a long way, but close by galactic standard.
