SpaceX successfully launches Falcon 9 rocket months after explosion

SpaceX launched its first rocket since a big explosion last year, when one of the private spaceflight’s rockets annihilated a $200m satellite in a spectacular and costly setback.
●    Saturday’s launch was SpaceX’s first since September, when a Falcon 9 rocket exploded on its launchpad at Cape Canaveral in southern Florida. 
●    The explosion destroyed the rocket and its payload, an Amos 6 communications satellite that Facebook wanted to use to provide internet to parts of Africa.
●    The accident grounded SpaceX’s fleet of reusable rockets, which had been steadily building a record of landings.
●    On Saturday the Falcon 9 rocket landed successfully on a barge in the Pacific Ocean, the first landing on a new drone ship there, prompting the engineers to burst into cheers.
●    Commissioned by the telecom company Iridium, the rocket carried 10 communications satellites into space, the first of an intended satellite “constellation” the Virginia-based tech giant means to use to replace its current global network of phone and data relays. 
●    Iridium has contracted SpaceX for $468m over seven launches.

Earth-like snow, ice features found on Pluto

Scientists have found evidence of Earth-like snow and ice features on Pluto, using a model similar to what meteorologists use to forecast weather on our planet and a computer simulation of the physics of evaporating ices.
●    The groundbreaking research, done in collaboration with researchers at NASA and Johns Hopkins University, indicates that these icy features may exist on other planets where environmental conditions are similar.
●    The identification of the ridges of Tartarus Dorsa as Penitentes suggests that the presence of an atmosphere is necessary for the formation of penitentes, which would explain why they have not previously been seen on other airless icy satellites or dwarf planets.
●    Pluto’s ridges are much larger — 500 metres tall and separated by three to five kilometres — as compared to their meter-sized earthly counterparts.

NASA's Curiosity discovers purple rocks on Mars

NASA’s Mars Curiosity rover has captured an up—close image of the red planet’s mountainous landscape, with purple-coloured rocks littered across the foreground.
●    The image captured from the Mast Camera (Mastcam) on Curiosity Mars rover shows purple—hued rocks near the rover’s late—2016 location on lower Mount Sharp.
●    The scene’s middle distance includes higher layers that are future destinations for the mission.
●    Variations in colour of the rocks hint at the diversity of their composition on lower Mount Sharp, NASA said.
●    The purple tone of the foreground rocks has been seen in other rocks where Curiosity’s Chemical and Mineralogy (CheMin) instrument has detected hematite.

ISRO successfully places remote sensing satellite Resourcesat-2A

ISRO successfully launched its own earth observation satellite Resourcesat-2A on 7 December 2016. 
●    The observation satellite Resourcesat -2A was launched with PSLV C36/ RESOURCESAT-2A from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
●    The PSLV-XL variant rocket standing 44.4 meters tall and weighing 321 tonne tore into the morning skies at 10.25am with a reverberating sound breaking free of the earth’s gravitational pull. 
●    The Resourcesat-2A weighing 1235 kilograms was injected into an 817 km polar Sun Synchronous Orbit (SSO) at around 20 minutes into the destination.
●    This satellite is intended to continue the remote sensing data services to global users provided by its two predecessors. 
●    The Resourcesat-2A carries three payloads which are similar to those of the earlier two Resourcesat’s. This mission will provide inputs in avionic science.
●    It carries two solid state recorders with a capacity of 200 Giga Bits each to store the images taken by its cameras. 
●    These images can be read out later to ground stations. The data sent by Resource would be analysed at Hyderabad from 15 December 2016.

MOM completes a revolution around Mars : ISRO

Mars Orbiter Mission (MOM), also called Mangalyaan, has completed one revolution around the Red Planet, Ritu Karidhal, deputy operation director of Bengaluru-based MOM ISRO Satellite Centre said.
●    The span of two years on Earth nearly equals to one year on Mars. 
●    The Mangalyaan, which entered into the orbit of Mars around two years ago, has completed one revolution. 
●    The ISRO scientist said the MOM could last in the space further for at least 5 to 10 years. 
●    The Mangalyaan does not have any fuel system to support its existence while orbiting Mars but is being purely driven by its different components. 
●    The life of these components would decide the future life of MOM.
●    Listing down some of the many firsts associated with MOM at the international level, including the mission that was successful in the first attempt, she said the greatest achievement of Mangalyaan was to infuse confidence among countrymen that India was second to none.

Cassini set to fly closest to Saturn's ring

NASA said its Cassini mission is set to begin on November 30 a daring set of “ring-grazing” orbits, during which it will fly closer to Saturns rings than it has since its 2004 arrival. 
●    On November 30, following a gravitational nudge from Saturn’s moon Titan, Cassini will enter the first phase of the mission’s dramatic endgame.
●    Launched in 1997, Cassini has been touring the Saturn system since arriving there in 2004 for an up-close study of the planet, its rings and moons. 
●    During its journey, Cassini has made numerous dramatic discoveries, including a global ocean within Enceladus and liquid methane seas on Titan.
●    Between November 30 and April 22, Cassini will circle high over and under the poles of Saturn, diving every seven days — a total of 20 times — through the unexplored region at the outer edge of the main rings. 
●    On many of these passes, Cassini’s instruments will attempt to directly sample ring particles and molecules of faint gases that are found close to the rings.
