Lasers in Space Broadband

            In this modern period thev internet connection isv gettingv slower and slower. So as to increase the speed and for faster communication with satellites, Nasa decided to use lasers. For decades radio waves were used for transmission between earth and satellites.. The transmission rates were in kilo bytes. Optical communication will be more efficient and faster to communicate, gather photographs, data, etc.

Laser communication is ideal for downlink communication from deep space. It will allow astronaut for making live videos at high resolution and getting feedback.. Both radio and laser travel at speed of light, but laser can travel with higher bandwidth than radio waves.. Our future communications will be made with laser.

Dawn discovers Organic Materials

      ESA's Dawn spacecraft had found some evidence for the presence of organic materials on the Ceres, a dwarf planet. It is the largest body in the asteroid belt, which is found between Mars and Jupiter. Scientists have found this organic material by visible and infrared mapping spectrometer in the northern hemisphere creator called Ernutet. This is the first clear detection of organic molecule from the belt. The presence of this organic molecule indicates the presence of life in the past... Previous study have found the presence of hydrated minerals, carbonates, water ice, ammoniated Clays that have been alerted by water..  Having completed two years of observations in orbit around Ceres. Dawn is now in an elliptical orbit at Ceres at an altitude of 5810 kilometres.. And it made a new altitude of 20000 kilometres on February 23, 2017.

Calabash Nebulae ( Rotten egg's Nebulae )

   The calabash nebulae is known as rotten egg nebulae, it is transitioning from red giant nebulae to planet nebulae.. It is located nearly 5000 light years from the Earth. It mostly contains sulfur, that's why it is called rotten egg's nebulae... This image has been taken by esa/ NASA Hubble space telescope..




It look like yellow color due to sulfur content. It moves with a speed of 1 million kilometer per hour...

The gas in blue is the surrounding material being pushed out of the way. The big acceleration likely started about 800 years ago,according to NASA. But the frantic pace won't last long, on a cosmic scale, before it transitions to a more long-lasting, slowly expanding feature.

Mars 2MV-3 No.1

LANDER DETAILS:-
Name              : Mars 2MV-3 No.1
Mission Type : Lander
Launch           : 4 November 1962
Rocket             : Molniya 8k78
Decay date     : 25 November 1962

DESCRIPTION:-

    Mars 2MV-3 No.1 also known as Sputnik 24 in the west. It was launched in 1962 as a part of Soviet Mars Programme in the carrier rocket of Molniya. It was aimed to land on Martian surface. But due to problem in the carrier rocket, the spacecraft did not depart low earth orbit.

CAUSES FOR FAILURE:

    After 4.2 minutes of flight, the oxidizer pressurization  malfunctioned which results in cavitation turbo pump. The same problem developed in propellant field lines, but still the lower stage were able to place spacecraft to LEO. The vibration in the cavitation system prevented the Block L upper stage from igniting, leaving the spacecraft in the parking orbit. It decayed in orbit next day. The upper stage ullage motor platform  remained in orbit until January 1963.

Mars 1 Flyby

Spacecraft Details:-

Name                         : Mars 1

Launch                     : 1 November 1962

Owner                      : Russia

Rocket                     : Molniya

Type                         : Probe / Flyby

Closest approach : 19 June 1963 

Description:-

                          Mars 1 also known as 1962 Beta No.1 Mars2MV-4 and Sputnik-23. It was launched on 1 November of 1962 as a part of Soviet Mars Programme with intent flyby of Mars at 11,000 Km. 

Objectives:-

  

          It was aimed to take image of Martian Surface and send back Cosmic data to the earth. It also designed to study the Mars Magnetic field, Mars Radiation Environment, Atmosphere structure and possible organic compunds.

Mission Status:-

          After leaving the earth Low Earth Orbit rocket Molniya's fourth stage separated and solar panel was deployed. Early telementry indicated that there was leak in one of the gas valve in the orientation system. So that the spacecraft transferred to gyroscopic stabilization. Later using Sixty One radio transmitters large amount of data were collected.

Causes for Failure:

             On 21st March 1963, the spacecraft is 106,760,000 km from the earth and on the way to Mars, thereafter the communication between Mars 1 and Telementry ceased,  probably due to the failure of spacecrafts antenna orientation system.

Scientific Results from Mars-1:

1. It recorded one of the micrometeorite outside Earth.
2. Magnetic field intensities of 3-4 nano teslas were detected.
3. Solar wind was detected.
4. Radiation Zone around the Earth was detected.          

Memories:-

               In later period Soviet Union published Mars 1 Stamp to remember the spacecraft. It was the spacecraft which lost its contact before flyby and it was close to Mars at a distance of 193,000 km.

NGC-6861 Hubble Space Telescope

This is NGC 6861, seen by the NASA/ESA Hubble Space Telescope. One of the Most prominent features in the disk of dark bands circling the centre of thus galaxy. These dust lanes are a result of large clouds of dust particles obscuring the light emitted by the Stars behind them.

The subject of this image is NGC 6861, a galaxy discovered in 1826 by the Scottish astronomer James Dunlop. Almost two centuries later we now know that NGC 6861 is the second brightest member of a group of at least a dozen galaxies called the Telescopium Group — otherwise known as the NGC 6868 Group — in the small constellation of Telescopium (The Telescope).

This NASA/ESA Hubble Space Telescope view shows some important details of NGC 6861. One of the most prominent features is the disc of dark bands circling the centre of the galaxy. These dust lanes are a result of large clouds of dust particles obscuring the light emitted by the stars behind them.

Dust lanes are very useful for working out whether we are seeing the galaxy disc edge-on, face-on or, as is the case for NGC 6861, somewhat in the middle. Dust lanes like these are typical of a spiral galaxy. The dust lanes are embedded in a white oval shape, which is made up of huge numbers of stars orbiting the centre of the galaxy. This oval is, rather puzzlingly, typical of an elliptical galaxy.

So which is it — spiral or elliptical? The answer is neither! NGC 6861 does not belong to either the spiral or the elliptical family of galaxies. It is a lenticular galaxy, a family which has features of both spirals and ellipticals.

The relationships between these three kinds of galaxies are not yet well understood. A lenticular galaxy could be a faded spiral that has run out of gas and lost its arms, or the result of two galaxies merging. Being part of a group increases the chances for galactic mergers, so this could be the case for NGC 6861.

A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Josh Barrington.
