Next for Isro: A mobile launchpad | India News - Times of India
BENGALURU: The next decade will be a compilation of milestones if everything goes as per plan for Isro, which, among many big ticket programmes in its pipeline, will also build a mobile launchpad for the proposed small satellite launch vehicle (SSLV) class of vehicles.

Isro’s PSLV turns money-spinner: Forex earnings rise by Rs 90 crore in ’18-19
Surendra Singh | TNN | Updated: Dec 16, 2019, 09:06 IST

NEW DELHI:

Indian Space Research Organisation
’s PSLV has turned into a money-spinner for the space agency as forex brought by the country’s mainstay rocket increased by Rs 90 crore from Rs 232.56 crore in 2017-18 to Rs 324 crore in 2018-19 fiscal year.


Isro has earned Rs 1,245 crore during the last five years by launching foreign satellites from 26 countries. Key contracts with 10 countries — the US, the UK, Germany, Canada, Singapore, The Netherlands, Japan, Malaysia, Algeria and
France — were signed in the last five years under commercial arrangements.


In financial years before 2017-18, the annual revenue figures just hovered around Rs 200-crore-plus mark. In 2016-17, it was Rs 208 crore, Rs 227 crore in 2015-16 and Rs 252 crore in 2014-15.


The information was provided to the Rajya Sabha in a written reply by Union minister for department of space Jitendra Singh in the just-concluded winter session. Though Isro’s market share in the global satellite launch market is less than 2%, PSLV has carved a niche for itself in the small satellite launch market and bringing in big moolah for the country.


Since May 26, 1999, when the first foreign satellite was launched by India, PSLV has till now launched 319 foreign satellites. Of the 319 satellites, which did not weigh more than 445kg, around 279 were launched in the last five years.


Keeping in mind the big market for small satellites, Isro has developed the Small Satellite Launch Vehicle (SSLV) or mini-PSLV, whose maiden test-flight is due in the first quarter of 2020.


In fact, the second demonstration test (D2) of SSLV has already been booked for carrying an American payload. The “vehicle-on-demand” SSLV can be assembled in just 3-5 days as compared to 30-40 days for a normal-size rocket and made in just one-tenth the cost of a PSLV. In 2018, 322 small satellites were launched globally through 44 launches, according to SpaceNews.


And the market witnessed a 23% compound annual growth rate from 2009 to 2018. According to a new market intelligence report by BIS Research, the global small satellite market generated a revenue of $513 million in 2018 and is expected to reach $2.9 billion by 2030 as over 17,000 small satellites are expected to be launched. Currently, US private space company Elon Musk-promoted Space X holds the lion’s share of the market.

Ambiguous missions (proposals and concepts without clarity)

GSLV MkIII (mated with SCE-200) or Unified Modular Launch Vehicle or Indian HLV/SHLV/Indian mission beyond solar system in late 2020s (or by UMLV or HLV?)

Indian SHLV with 100 tonnes capacity to LEO (concept abandoned in 2010)

UMLV's SHLV variant with 35 tonnes in GTO and 61.3 tonnes to LEO (proposed in 2014 and updated in 2018, to use clustered SCE-200 engines.

SHLV/Indian manned mission to Moon

Near future milestones to follow:
First launch, autonomous landing and return flight of ISRO's TSTO Reusable Launch System Technology Demonstrator

First launch, autonomous landing and return flight of DRDO's TSTO AVATAR

First launch, autonomous landing and return flight of India's SSTO ADMIRE test vehicle

Successful trial run of SCE-200 to be achieved in 2020 and first flight on GSLV MkIII after 2022

Let's see how much they are able to complete on time. Not definitely will meet schedule without one more launch pad, another satellite integration factory and nearly double of budget they operate at right now.

Have tech to configure launch vehicle that can carry 50-tonne payload: ISRO chairman

Eventually, when US operationalizes SLS and China tests Cheng Zheng 9, India will naturally shift its target to achieve 100-150 tonnes.

Yes, after Shukrayaan-1, another Venus flyby will be launched that is to be redirected to Jupiter after achieving required velocity and periapsis. Announced last year.

GSLV MkII F??/Indian lunar telescope in 2020s

Details on this please.

Are we talking about landing a telescope observatory on the far side of the moon (to cut out light & interference from Earth)?

Is this mission sanctioned?

Yeah

Is this mission sanctioned

Proposed only. Mentioned by officials one or two types. I will have to rummage all space threads to find them.

For sure, after soft landing either sample return or this will be India's next aim for moon.

No.... Idea is to launch a space based telescope that would revolve around moon instead of earth for observation.

No, I guess it was landing on far side?? You remember where the url is?

 

[Chinmoy]

Naah.


India cant afford such a mission. Landing a telescope on far side of moon has its own problem which till now has not been solved.
To start with, a telescope on far side of moon in itself cant upload data or download commands from earth. It would need a constant rover in axis to do that or an array of stationary relay. Its a lot costlier plan to implement in 2020 itself. Moreover a stationary telescope on surface is best for observation, but it would have to overcome the challenge of moonquakes which could last for an hour of so, sub zero frigid temperature which would mean any kind of power supply would not work for long enough.

So in 2020, no way we could expect a surface based lunar telescope.

I would like to add one more problem to that.

even if we(or anyone for that matter) managed to place a telescope it'll be useful for onl 13 or 14 days or so.

Because, it takes 655.72 hours(approximately 28 days) to spin its axis. Meaning,14 days of night and 14 days of bright days under harmful radiation. Hence the equipment will not be useful for half of its mission life.

Even the hubble with low earth orbit is posing its limit because of the proximity to sun.
That's why jwst slated for deep space deployment with tennis court sized sun shades.


"dark side of the moon l"is a misnomer,because its orbit is face locked with earth,so we can't the other side of the moon. But all parts of the moon experience day and night similar to earth

Got it..

The agency is looking at what could be the next Astrosat-follow on mission. Speaking to the students of the Indian Institute of Technology, Madras, he said, "There is some discussion with an international body, and this discussion is in progress, on whether we can set up a telescope on moon."

The underlined and colored part basically gives an idea of what ISRO wants.

Isro signs pact with astrophysics institute to set up optical telescopes

NEW DELHI: Indian Space Research Organisation has inked a pact with Indian Institute of Astrophysics (IIA) to pave the way for collaboration in establishing optical telescope facilities under Project ‘NETRA’ for tracking space objects. The agency has also tied up with NIT-Karnataka to set up a regional academic centre for space to promote research in space technology.

Indian scientists spot a galaxy 260 light-years away that isn't giving birth to any new stars

• in India have a spotted galaxy AGC 203001 with a large ring of hydrogen gas wrapped around it.
• The galaxy is 260 lightyears away from Earth.
• Normally, reservoirs of neutral hydrogen gas are accompanied by star formation, but there are no new stars being born in this ring of hydrogen.

Galaxies are made up of interstellar gas, cosmic dust, entire solar systems, and stars. Normally, these stars are born in clouds of neutral hydrogen gas. More gas, more stars.

However, one galaxy 260 light-years from Earth shows zero signs of star formation despite having a ring of hydrogen gas four times the size of the Milky Way around it.
