After the Moon and Mars, ISRO eyes Venus for next exploration mission

earth-2
After the successful launch of its Mars orbiter, the Indian Space Research Organisation (ISRO) is now viewing Venus as possibly the next planet it can study and explore.
“Besides the Mars-2 mission, we are looking at Venus and even an asteroid for exploration. A project has to be formulated for this before we chart out a proper roadmap for the explorations.  Venus is our neighbour and has many scientific challenges and aspects that need to be studied. Exploring an asteroid is also challenging task,” Dr Kiran Kumar, Isro chairman, told HT.
In 2014, India created history in space when its Mars orbiter slipped into the Red Planet’s orbit in its maiden attempt.
India became the first Asian country to reach Mars and the first in the world to enter the orbit of the planet in its first attempt.

Regarding the Saarc satellite, Dr Kumar said that it would be launched before December 2016. “The activities related to this project are in progress and we should begin building the satellite soon.”
Moving beyond satellite launches and planetary explorations, Isro is also aggressively working with many government departments on optimising the usage of space tools and data.
A national meet on space is likely to be held in Delhi next month, where ministries and departments of the government will give presentations on how they are using space tools in their workings. From civil aviation to railways, tribal affairs to health, postal to agriculture the number of government departments working with Isro has increased to more than 60 in the past few months.

Biggest commercial mission! ISRO to launch 5 British satellites on July 10


Indian Space Research Organization (ISRO) on Sunday announced that it will be launching five British satellites on July 10, which will be the thirtieth flight of the PSLV (Polar Satellite Launch Vehicle) and the biggest ever commercial mission by the Indian space reasearch centre.

In the heaviest ever commercial mission undertaken by ISRO and its commercial arm Antrix, the country’s workhorse the Polar Satellite Launch Vehicle (PSLV) will put in orbit five foreign satellites from the spaceport of Sriharikota in Andhra Pradesh on July 10.

With the overall lift-off mass of the five satellites amounting to about 1,440 kg, this mission becomes the heaviest commercial mission ever undertaken by Antrix/ISRO, the Indian space agency said.
In its 13th flight, PSLV-C28 will launch three identical DMC3 optical earth observation satellites built by Surrey Satellite Technology Limited (SSTL), United Kingdom (UK).

The three DMC3 satellites, each weighing 447 kg, will be launched into a 647 km Sun-Synchronous Orbit (SSO) using the high-end version of PSLV (PSLV-XL), ISRO said on its website.  PSLV-C28 will be the ninth flight of PSLV in ‘XL’ configuration.

In addition, the rocket will also carry two auxiliary satellites from UK - CBNT-1, a technology demonstrator earth observation micro satellite built by SSTL, and De-OrbitSail, a technology demonstrator nano satellite built by Surrey Space Centre, it said.

Accommodating the three DMC3 satellites each with a height of about 3 metre within the existing payload fairing of PSLV, was a challenge, ISRO said.

To mount these satellites onto the launcher, a circular Launcher adaptor called L-adaptor and a triangular deck called Multiple Satellite Adapter-Version 2 (MSA-V2), were newly designed and realised by ISRO for this specific purpose.

Dwarf planet Ceres reveals pyramid-shaped mystery



OK, this is just too much.
First, NASA's Dawn probe spotted curiously sparkly bright spots on the surface of Ceres, the dwarf planet that lies in the asteroid belt between Mars and Jupiter.
Beats us, the scientists said.
Now, cameras on the tractor-trailer-size spacecraft have captured a baffling structure rising 3 miles above the planet's cratered surface.
Conveniently, the thing looks an awful lot like a pyramid.
    "Intriguing," the NASA scientists said.


    To be fair, the agency offered no suggestion that the towering structure is an offering to some long-lost space emperor or home to our new alien overlords.
    And, to be even more fair, it's probably just a really tall mountain in a solar system filled with wondrous and strange natural phenomena.
    But the Dawn mission has done nothing but stoke imaginations since the discovery of mysterious bright spots on the surface of the dwarf planet in February and the beginning of the probe's orbit in March.
    Folks have claimed to have spotted giant alien motherships hovering over the planet, bat-winged spaceships parked on its surface and even evidence of alien cities.
    But the mystery only deepened with the most recent batch of images showing even more bright spots alongside the largest one, which NASA said looks to stretch some 6 miles.
    Many, of course, insist that the spots look for all the world like brightly lit cities twinkling on the shadowed surface of the distant dwarf planet.
    I knew it! There's gambling going on on Ceres! #aliens pic.twitter.com/QP6PB6JFho

    — Chris Reher (@Chris_Reher) June 13, 2015
    Of course, NASA hasn't traveled down that road. Scientists, they say, still don't know what the spots are. Maybe ice. Maybe salt.
    "But scientists are considering other options, too," NASA said coyly.
    But #itsaliens, right?

    A team of NASA researchers has found that 3D manufactured copper parts could withstand the heat and pressure required of combustion engines used in space launches.

    The US space agency and California-based rocket and missile propulsion manufacturer Aerojet Rocketdyne (AR) conducted 19 hot-fire tests on four injector and thrust chamber assembly configurations at NASA's Glenn Research Centre.

    "The successful hot fire test of engine components provides confidence in the additive manufacturing process and paves the way for full-scale development," said Tyler Hickman, lead engineer for the test at Glenn.

    3D printing approach is changing the speed, cost and flexibility of designing and building future machines for space and earth applications.

    The work is a major milestone in the development and certification of different materials used in the manufacturing process.

    Copper alloys offer unique challenges to the additive manufacturing processes.

    "Additively manufactured metal propulsion components are truly a paradigm shift for the aerospace industry," added Paul Senick, Glenn project manager.

    This will improve efficiency and bring down the cost of space launches and other earth applications, he concluded.

    The Indian Space Research Organisation (ISRO) is planning to launch second mission to Mars with a lander and rover to carry out more experiments on the red planet.

    The proposed plans come after the Indian space agency has successfully placed its unmanned Mars Orbiter Mission spacecraft to the Martian orbit in September.

    ISRO satellite centre director Shiva Kumar was quoted by IANS as saying: "We plan to launch a second mission to Mars in 2018, probably with a lander and rover, to conduct more experiments for which we have to develop new technologies.

    "We will be able to take the Mars-2 mission after launching the second mission to the moon (Chandrayaan-2) in 2016 with our own lander and rover, which will help us develop a separate lander and rover for the red planet."

    The agency is looking to launch the programme in 2018 as the missions to Mars can be launched at two year intervals.

    ISRO intends to have fully operational heavy rockets ready by then to carry communication satellites weighing around 3t into the geo-stationary orbits around the earth.

    In line with this plans, the agency has developed the geo-synchronous satellite launch vehicle (GSLV Mark I-III) to launch heavier communication satellites.

    GSLV Mark-III is scheduled to take its first partial test flight in early December.

    ISRO chairman Radhakrishnan was quoted by The Hindu as saying that the test flight will lead to a 'future workhorse vehicle that will stay with us for many years'.

    Tests will be conducted on unmanned crew module of the three-stage launch vehicle, to evaluate heating during its re-entry and its behaviour in the crucial space phase.

    Isro to Test Crew Module in December for India's First Human Space Flight

    index

    India will launch an unmanned crew module in December onboard a heavy rocket to test its re-entry into the atmosphere for the country's maiden human space flight, the space agency chief said Thursday.
    "We will send an unmanned crew module on the experimental GSLV-Mark III rocket in December and test its re-entry into the earth's atmosphere for a human space flight plan in future," Indian Space Research Organisation (Isro) Chairman K. Radhakrishnan told reporters in Bangalore on the margins of an engineers conclave.

    Weighing 3.6 tonnes, the crew module will be put into orbit 100-120km up in a satellite and brought back to Earth for checking its re-entry characteristics when carrying two Indian astronauts in the proposed human space flight.

    "Though the actual human space flight will be in an orbit around earth at a height of 270km for a week, the experimental flight with the crew module in a spacecraft will go up to 100-120km above earth to test its heat shield survive very high temperatures (about 1,500 degrees Celsius) during the re-entry into the atmosphere," Radhakrishnan noted.

    The crew module will have a parachute that will open up after re-entry into the atmosphere and fall into sea for retrieval.

    "The parachute will open up for soft landing of the spacecraft carrying the crew module in the Bay of Bengal, about 450 km away from Andamans (islands), and will be retrieved by a boat," Radhakrishnan said.

    The previous UPA government had sanctioned Rs. 145 crores to Isro for developing a crew module that will fly two Indian astronauts into space, space suits, life support systems and related technologies for the human space flight programme.

    The heavy rocket (GSLV) will, however, have a passive cryogenic stage - liquid nitrogen at super cooled temperature and gaseous nitrogen instead of liquid hydrogen and liquid oxygen.

    The space agency is integrating the rocket with the crew module at its Sriharikota spaceport in Andhra Pradesh, about 90 km northeast of Chennai.

    China's Main Competitor in Space Exploration is India, Not Russia

    China-India-Flag

    China's principal competitor in space exploration is India, not Russia, researcher at the Russian Centre for Analysis of Strategies and Technologies Vasily Kashin told RIA Novosti on Friday.

    "China and India are two new space powers. They have vast resources and consider their space programs from the national prestige perspective ," the expert said.

    He added that China and India are following Russian and US footsteps in space exploration.

    "China's more developed space-rocket industry and immense resources have let it take the lead in the two countries' space race," Kashin argued.

    Despite being behind China in space exploration, India has a significant advantage, according to the researcher.

    "China is still under rigid restrictions on any form of cooperation with the United States, including on the purchase of components...The Chinese are forced to do many things on their own and they sometimes cannot produce components of a required level. The Indians have less resources, but they are in good relations with everyone. India can cooperate with both Russia and the West, adopting their best technologies," Kashin concluded.

    Earlier on Friday, China launched an experimental spacecraft to the moon orbit, which is to return to Earth in eight days. The spacecraft is to test out re-entry into the Earth's atmosphere for the planned 2017 Chang'e-5 lunar mission.

    GSLV-Mark III launch in 45 days, says ISRO chief

    150015_fb0b03b52e6adf08510aa2e7f189739b

    A step closer to sending astronauts into space



    In just 45 days from now, Indian Space Research Organisation (ISRO) would launch its most ambitious suborbital — less than the usual orbit- test flight — Geosynchronous Satellite Launch Vehicle (GSLV) Mark III.


    It will be an unmanned crew module. This will unleash India’s dream of sending its astronauts into space come true.


    “We will comeback soon with an unmatched module in the next 45 days. GSLV Mark III will be one of the heaviest indigenous launch vehicles,” said K. Radhakrishnan, Chairman, ISRO, after the launch of PSLV C26, IRNSS-1C, the third satellite of the Indian Regional Navigation Satellite System from the first launch pad of Satish Dhawan Space Centre in Sriharikota.


    The GSLV Mark III will help ISRO put heavier communication satellites of INSAT-4 class into orbit. These satellites weigh anywhere between 4,500-5,000 kg. The vehicle is 42.4 metre tall compared to the other GSLV which is 49 metre. It will be a three-stage vehicle.


    “We are already working on this next launch. The work is completed and in testing stages,” Y.S. Prasad, Director, SHAR, said.


    Terming the Mark III mission as most important and challenging, M. Chandradathan, Director of Liquid Propulsion Systems Centre of ISRO, said: “It is one of the heaviest indigenous launch vehicles that is been developed till date.”


    The launch of GSLV Mark III will enhance India’s capability to be a competitive player in the multimillion dollar commercial launch market.


    The vehicle envisages multi-mission launch capability for GTO (geo transfer orbit), LEO (low earth orbit), Polar and intermediate circular orbits.

    India reaches Mars, Prime Minister Narendra Modi showers praises on ISRO

    mangal

    India scripted history on Wednesday,24 September with the success of its Mars mission. As the Mangalyaan entered the Mars orbit, making India the first country in the world to make it to the Red Planet in the first attempt. Mangalyaan moved a step closer to home after the dormant main engine on the spacecraft was test-fired flawlessly, ISRO looked confident of giving one final nudge to put it in orbit around Mars that saw it make space history. - See more at: http://indianexpress.com/article/india/india-others/live-indias-mars-mission-mangalyan-red-planet-mars-orbiter/#sthash.240P3tKY.dpuf
