After clearance of budget last year by government, it's an official statement from ISRO about our Son of the Sun-
:hurray: Aditya L-1 :hurray:

Aditya - L1 First Indian mission to study the Sun
The Aditya-1 mission was conceived as a 400kg class satellite carrying one payload, the Visible Emission Line Coronagraph (VELC) and was planned to launch in a 800 km low earth orbit. A Satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/ eclipses. Therefore, the Aditya-1 mission has now been revised to “Aditya-L1 mission” and will be inserted in a halo orbit around the L1, which is 1.5 million km from the Earth. The satellite carries additional six payloads with enhanced science scope and objectives.

The project is approved and the satellite will be launched during 2019 – 2020 timeframe by PSLV-XL from Sriharikota.

Aditya-1 was meant to observe only the solar corona. The outer layers of the Sun, extending to thousands of km above the disc (photosphere) is termed as the corona. It has a temperature of more than a million degree Kelvin which is much higher than the solar disc temperature of around 6000K. How the corona gets heated to such high temperatures is still an unanswered question in solar physics.

Aditya-L1 with additional experiments can now provide observations of Sun's Photosphere (soft and hard X-ray), Chromosphere (UV) and corona (Visible and NIR). In addition, particle payloads will study the particle flux emanating from the Sun and reaching the L1 orbit, and the magnetometer payload will measure the variation in magnetic field strength at the halo orbit around L1. These payloads have to be placed outside the interference from the Earth’s magnetic field and could not have been useful in the low earth orbit.





The main payload continues to be the coronagraph with improved capabilities. The main optics for this experiment remains the same. The complete list of payloads, their science objective and lead institute for developing the payload is provided below:

  • Visible Emission Line Coronagraph (VELC): To study the diagnostic parameters of solar corona and dynamics and origin of Coronal Mass Ejections (3 visible and 1 Infra-Red channels); magnetic field measurement of solar corona down to tens of Gauss – Indian Institute of Astrophysics (IIA)
  • Solar Ultraviolet Imaging Telescope (SUIT): To image the spatially resolved Solar Photosphere and Chromosphere in near Ultraviolet (200-400 nm) and measure solar irradiance variations - Inter-University Centre for Astronomy & Astrophysics (IUCAA)
  • Aditya Solar wind Particle Experiment (ASPEX) : To study the variation of solar wind properties as well as its distribution and spectral characteristicsPhysical Research Laboratory (PRL)
  • Plasma Analyser Package for Aditya (PAPA) : To understand the composition of solar wind and its energy distribution –Space Physics Laboratory (SPL),VSSC
  • Solar Low Energy X-ray Spectrometer (SoLEXS) : To monitor the X-ray flares for studying the heating mechanism of the solar corona – ISRO Satellite Centre (ISAC)
  • High Energy L1 Orbiting X-ray Spectrometer (HEL1OS): To observe the dynamic events in the solar corona and provide an estimate of the energy used to accelerate the particles during the eruptive events - ISRO Satellite Centre (ISAC)and Udaipur Solar Observatory (USO), PRL
  • Magnetometer: To measure the magnitude and nature of the Interplanetary Magnetic Field –Laboratory for Electro-optic Systems (LEOS) and ISAC.
With the inclusion of multiple payloads, this project also provides an opportunity to solar scientists from multiple institutions within the country to participate in space based instrumentation and observations. Thus the enhanced Aditya-L1 project will enable a comprehensive understanding of the dynamical processes of the sun and address some of the outstanding problems in solar physics.

India's 1st solar mission to help address some problems in solar physics: ISRO

Aditya - L1 will be launched on board launch vehicle PSLV-XL from the spaceport at Sriharikota in Andhra Pradesh.
BENGALURU: India's first mission to study the Sun, Aditya - L1, will help address some of the outstanding problems in solar physics, Indian Space Research Organisation said today.

Expected to be launched during 2019-20, it will enable a comprehensive understanding of the dynamic processes of the sun, it said.

The mission was first conceived as Aditya-1 mission as a 400 kg class satellite carrying one payload, the Visible Emission Line Coronagraph (VELC).

It was planned for launch in an 800 km low earth orbit.

The mission has now been revised to 'Aditya-L1 mission' because satellite placed in the hallowed orbit around Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation or eclipses.

The satellite will be inserted in a halo orbit around the L1, which is 1.5 million km from Earth, ISRO said, adding that it would also carry additional six payloads for enhanced scientific scope and objectives.

Aditya - L1 will be launched on board launch vehicle PSLV-XL from the spaceport at Sriharikota in Andhra Pradesh.

Earlier, Minister of State in the Prime Minister's Office Jitendra Singh had in a written response in the Lok Sabha said that the "approved cost" of the solar mission is Rs 378.53 crore.

ISRO said Aditya-1 was meant to observe only the solar corona, while Aditya-L1 with additional experiments can now provide observations of Sun's Photosphere (soft and hard X-ray), Chromosphere (UV) and corona (Visible and near infrared (NIR).

In addition, particle payloads will study particle flux emanating from the Sun and reaching the L1 orbit, and the magnetometer payload will measure the variation in magnetic field strength at the halo orbit around L1, it added.

Please read my earlier replies on the thread.
There's mention of Chandrayaan 3&4 and 25 tonne capacity Delta IV like Indian Rocket officially by ISRO chief.
The quoted post is by @Gessler but I don't know how it is ascribed to me!!

Kineco Kaman's antenna put into orbit via ISRO satellite

DHAA was manufactured by Kineco Kaman for ISRO's Vikram Sarabhai Space Centre (VSSC) in Trivandrum and was integrated into IRNSS-1E. (Representative Image)
PANAJI: Kineco Kaman Composites India (KKCI) has become the first private company in India to manufacture a Dual Helix Antenna Array (DHAA) assembly, which was launched into the space aboard ISRO's fifth Indian Regional Navigation Satellite (IRNSS-1E) this month.

"The DHAA assembly is a very complex and high precision structure made using a combination of Carbon and Aramid Composites. The manufacturing of this DHAA requires hi-tech engineering and manufacturing competence, benchmarked with the best in the world," said Shekhar Sardessai, Chairman and MD, Kineco Kaman Composites-India Private Limited.

IRNSS is a cluster of seven satellites comprising three geo-stationary and four geo-synchronous satellites.

DHAA was manufactured by Kineco Kaman for ISRO's Vikram Sarabhai Space Centre (VSSC) in Trivandrum and was integrated into IRNSS-1E, which was successfully put into the orbit by PSLV-C31 on January 2, he said.

"The IRNSS will be the Indian version of the global positioning system (GPS) and will be called Standard Positioning Service (SPS). Once all the satellites are placed in orbit, which is expected to be by March 2016, free SPS services will be available to all civilians," Sardessai said.

Kineco Kaman -- a joint venture of Kineco Group Goa, India and Kaman Aerospace Group-USA -- had earlier received a contract for the manufacture and supply of 10 sets of DHAA assemblies for VSSC Trivandrum in 2015.

In a thread regarding ISRO putting the manned spaceflight mission on hold, I had made the following statement regarding our 2nd Mars mission;

The second Mars mission has a window in 2018 if I remember correctly. We shouldn't miss that at any cost. We have a great head-start over our rivals in Asia as far as Mars exploration goes, plus we've been putting the MOM to good use so far. Shouldn't let that lead slide.
http://defenceforumindia.com/forum/...r-robotic-mission-instead.75020/#post-1123042

As many members already shared & posted here, during Hollande's visit, India & France had signed MoUs between ISRO and the French space agency CNES concerning this very mission. If you guys recall, ISRO wanted to put a lander (and possibly a rover) on Mars in it's second mission.

As the 2018 window is closing in fast, I believe ISRO has made the call to diversify the work-share between the space agencies of friendly countries in order to meet the target within the specified deadlines. And yes, you can say these deadlines are so important as they were written by the cosmos themselves.

I just want to congratulate the scientists for their straightforward thinking. Indeed, with the work being shared between Indian agencies (ISRO, SAC, etc.) and CNES, we should be able to meet the deadlines and launch our spacecraft right through the 2018 window.

With this, India will fully cement it's position as the leading interplanetary explorer in Asia.

I think China was corporating with Russia for it's next Mars Mission Yinghuo-2 in 2020. They wanna land a rover in first try.

Current priorities of ISRO:
1. Completion of IRNSS.

2. Commercialization of GSLV MarkII.

3. Operationalization of GSLV MarkIII.

4. Putting Chandrayaan 2 on Moon.

5. Putting GSAT-11 in orbit.

6. Putting Aditya L-1 in Sun's orbit about 1.5 million km away from earth.

7. Executing a second Mars mission to ensure about nation's capability of sending interplanetary missions.

8. Building a scaled down prototype of AVATAR.

9. Completion of third advanced launch pad.

10. Expertizing robotic and rover technologies because we are good at building orbiters but kids in case of rovers and sample return missions.
That's why ISRO decided to delay manned mission.

Non - priority:
1. Sending Humans in Space.

2. Replacing current rocket family based on LOX by cryogenic ULVs.

3. Developing Heavy Lift Cargo Rocket for building Space station (project is being studied since 2010).

4. Sample return mission to Moon
(A wish of ISRO which it was unable to achieve till today due to budget shortage. They have tried many times even with foreign help but anything always stops them. But now, they are deciding to go alone).

5. A Venus Mission (has been in study many times but currently out of priority).

6. An asteroid mission
(Sometimes ISRO officials talk about it in media but little details are available).

7. A super heavy rocket roughly capable to put a small craft on Moon.
(First heard in 2010, not much news and updates are coming about it.)

Correct if I'm wrong and add if I'm missing something.

Did you just connect the dots to arrive at this conclusion or has any ISRO official stated (on or off the record) that a space station project is being mooted?

Ofcourse HLV/SHLV-type rockets will grant us the ability to build space stations as well as throw really large/heavy modules...however it doesn't seem ISRO has put these views forward as yet.

SHLV was dreamed long ago around from time Shri Atal Bihari Vajpayi(and will be needed when we go for Moon in long term) but HLV program is alive both in Media and official sources. I have provided many official and unofficial links about this vehicle family on forum.
When ULV family will be operationalized capable of lifting 1.5-6 tonnes to GTO, a new HLV family will be put on development of capacity around 6 tonnes to 10 tonnes to GTO(around 20-25 tonnes to LEO).
Many times ISRO scientists mention about this rocket. Also, third launch pad under construction in SriHariKota has capability to serve a heavy rocket.
So, it proves that ISRO may be developing one. Otherwise, they may not have made it capable to do that.
It's official. :)

ISRO to launch 2 satellites before March 31

Mayilswamy Annadurai, Director of ISRO Satellite Centre, interacts with students.File photo
Indian Space Research Organisation (ISRO) will launch the last two of the seven constellational satellites by March 31. The satellites -- 1 F and 1 G -- of theIndian Regional Navigation Satellite System will be ready for launch before March end, said Dr. Mylswamy Annadurai, Director, ISRO Satellite Centre here on Saturday.

Speaking on the sidelines of an event in a private school here, the ISROscientist said the Rs.1,350 crore IRNSS project has a total of 9satellites, with 7 satellites on the orbit and 2 satellites as stand-by.

According to Dr. Annadurai, once the final satellites are launched, the IRNSS would place India on a par with the US that ruled the orbit with its advanced American Navigation Satellite System. Tracing the timeline of the IRNSS project, Dr.Mylswamy said the first satellite 1 A was launched in 2013, followed by satellites 1 B and 1 C in 2014; 1 D in 2015 and 1 E in January this year. On ISRO’s successful Mars Probe Mangalyan, he hinted at a possible order that will allow outsiders (foreign scientists and research institutions) to use the Mars Orbiter Mission for their research. “An order to that effect is likely to be released soon,” he said.

And I've told it before guys. :)

NASA, India Join Hands for Astrobiology Mission :india:

For the first time India is part of Spaceward Bound program, which funds expeditions to places with extreme climate conditions

Even as India prepares for a second mission to Mars, a team of scientists from the National Aeronautics and Space Administration (NASA), the Mars Society Australia and the Birbal Sahni Institute of Palaeobotany, Lucknow, will mount an expedition to Ladakh this August to study the similarities of certain parts of the region’s topography and microbial life to Martian surroundings.

India’s second mission to Mars — scheduled to be in 2020 — will involve collaboration with France and may include a lander or rover — remote controlled vehicles — which can ostensibly better analyse a planet’s surface.


“This is the first time that India is part of the Spaceward Bound programme,” said Siddharth Pandey, who is among the coordinators of the expedition “and we hope to have the Indian Space Research Organisation (ISRO) closely involved.” The Spaceward Bound is a NASA project that educates future space explorers and funds expeditions to places with extreme climate conditions.:india:
Before Ladakh, there have been expeditions to the deserts such in Atacama, Chile; Mojave, California; Arkaroola, Australia as well as the Arctic and Antarctica, organised since 2006.


Low-Cost Mars Mission
The success of India’s low-cost mission to Mars, in 2014, has led to heightened international interest in collaborating with India’s upcoming space missions. India now has an orbiter that's still circling Mars and taking pictures — with five instruments on board — in hopes of finding methane, carbon dioxide and the effect of solar winds on its surface. “Ladakh has been studied before but this time we’re going to be looking at some very specific experiments,” said Mr. Pandey — an engineer from India and who’s previously worked at the NASA. “We will be testing a rover that will collect samples and analyse some of the high altitude springs etc.”

According to the program’s website, Ladakh offers a “high UV (ultra-violet) exposed, dry ecosystem with Mars analogue topological features that tell us heaps about the origin and evolution of our planet’s topological features…”

Before its Mars Mission, the ISRO has Chandrayaan 2 planned to the moon, in 2017, that too hopes to set a lander on the surface of the moon.

The Birbal Sahni Institute of Palaeobotany, which has expertise in studying ancient climate and life, will be coordinating the travel of scientists and researchers from several countries who will be part of the 10-day expedition.

Along with research experiments, the group would also meet school students and organise sessions on how astrobiology missions work, the evolution of life on earth as well as on how space missions work, Mr. Pandey added.

France, India charting new orbit to jointly explore Mars, Venus: Jean-Yves Le Gall, French Space Agency

NEW DELHI: With Mangalyaan already an orbiter, putting a lander on Mars would be an interesting prospect and France is ready to work with India on it, says the chief of French Space Agency. In an interview with Pallava Bagla, Jean-Yves Le Gall hopes that Indian and French flags could fly to Mars and Venus.

Excerpts:
What is the agreement that has been signed between India and France on the upcoming mission to Mars?

It is related to exploring Mars. We know the ambitions of India to explore the Red Planet. We are very very impressed with what India is doing with Mangalyaan, which is currently orbiting Mars. In France, we have very skilled scientists for both Mars and Venus. Since there is already a project to explore Mars in India, we implemented an agreement to co-operate in the future on this project.


So can one say, India & France will jointly go to Mars whenever the next mission happens?
On the next Indian mission to Mars, there will be a piece of French expertise. We are very proud of that since we have a long-standing co-operation with India in many different fields and now we are opening a new field with exploration of space.

So will France consider putting a lander on Mars along with India, since Mangalyaan is already an orbiter?
It is clear that once you put a satellite in the orbit of Mars, the next step is a lander. It is not so easy, but since we are very skilled I am quite optimistic.


So France is looking for a lander, which is one-step ahead and a big jump for India?
A lander on Mars would be very interesting, and we are ready to work on it.

What do you think of India's maiden mission to Mars, Mangalyaan?
The mission is very impressive, it is a good example of 'Make in India' because total cost of Mangalyaan is USD 60 million, which is lower than the cost of making the Hollywood blockbuster movie, Gravity. So it clearly shows that without big means but being very very smart:india: you can perform very ambitious space missions, perhaps we can say at a low cost.


Is France also looking for co-operation with India to study planet Venus?
With the global cost of space missions coming down, a mission to Venus can be considered at a much lower cost than a few years ago, so it is feasible. Hence, why not go to Venus.

France and India also inked an agreement to make a new thermal imaging satellite, what is this mission?
This new satellite mission is really a follow up of the climate change meeting that took place recently in Paris and we decided to take it forward. We already have two joint satellites in space that are devoted to observation of climate, Megha-Tropiques that was launched in 2011 and SARAL-ALTIKA that was launched in 2013.

Now we are going to develop a new satellite specifically devoted to the observation of climate change. Observing the earth's surface in thermal-infrared. This special band of wavelength will help monitor climate change.

This will help understand what are the effects of climate change on vegetation. The three Indo-French joint earth observation satellites will help provide a better picture on how climate is changing.

At the Indo-French Summit more agreements were signed on space than other areas, what is the third agreement about?
On India's upcoming OceanSAT satellite France will put an ARGOS payload, which will be devoted for search and rescue beacons using space as a platform.

Where is the Indo-French partnership headed?
Both countries have great heritage of co-operating in space, both on rockets and satellites. French launchers launch Indian communications satellites and Indian rockets have launched French satellites. Today India is becoming the second biggest partner of France in space technologies, outside of Europe.

How do you rate and compare the Indian space agency with other space agencies of the world?
I am always very impressed when I visit centres of the Indian Space Research Organisation (ISRO). What is most impressive is that people are fully dedicated; they have the same level of dedication as we had or America had in the early days of the space program. In India there is the kind of enthusiasm and freshness, which is very very refreshing, which leaves a lot of room for optimism in the future.

Well, I think major contribution by France may be funding better.
All tech for Mangalyaan 2 can be demonstrated in upcoming Chandrayaan 2, 3 and 4.
