Each payload needs to eject from vessel & put accurately in orbit, so it count each payload as a mission.

That is different from what other countries count a mission. For example, the voyager II that visited multiple outer solar system planets count as 1 single mission. Thanks for sharing this with me.

Space mission counting by India's method: Double Counting
ISRO scores on 100th mission, PSLV rocket launch successful

Yankees space enthusiast opinion on the India's method

The space agency has undertaken 99 missions, including 62 satellites and 37 launch vehicles, since the launch of the Aryabhatta in 1975.
--------------------------------------------------------------------------------------------

They've miscounted.
4 SLV + 4 ASLV + 21 PSLV + 7 GSLV = 36 launches.

This is the 22nd PSLV, and the 37th launch overall, so assuming they do have 62 satellites (I don't have time to check), this is actually the 99th "mission", not the 100th.

That said, counting both launches and missions together does look as if they are trying to manufacture a milestone where none exists.

India only has light weight launcher now. Once it has heavier weight launcher, it can launch heavier satellites.

How ISRO numbers is mission is for it's own.. they don't give a rats a$$ as to how some junk agency continents apart counts their chickens

Yeah, India isn't Russia who has been doing this for so long.

So India completed 8 missions today ! Well done.

SARAL------------------346 kg occupy LEO
Sapphire------------------~150 kg occupy LEO
NEOSSAT------------------65 kg occupy LEO
UniBRITE (CanX 3A)------------------10 kg
TUGsat 1 (BRITE-Austria, CanX 3B)------------------10 kg
STRaND 1------------------3.5 kg
AAUSAT 3------------------1 kg

Only one payload is Indian, they will number it 2 by counting the Indian payload and the launch together, India has finish two "missions" in a single day.

Mr j-20 will you please get out of this thread

Thank you

Well done ISRO..... You make us proud time and again..... Please make us proud for 1 more time with GSLV...... And Wish you all the best for it....

 

[Markus]

PSLV is good but we need the GSLV for bigger payloads.

Looks like you are right. Foreign Satellites are not counted. So this is counted as 2 missions. This is so confusing. Even Indian can get it wrong.

Not a bad achievement, considering at one point of time, the journey began like this,

AM surfing through other forums...and guess what.......................

Brits whining about their Aid money.....

give me the link

 

[gubbi]

How about putting some nuclear warheads into orbit by PSLV in disguise of a satellite???
Is that any way feasible ??? But if we put NWs into orbit.....we can drastically reduce our reaction time in case of an emergency....

Its a preposterous and an outrageous proposition. It can even be called stupid! Even the superpowers in their heyday did not put weapons in space (except for a Almaz satellite carrying a cannon and handguns carried by Soviet/Russian cosmonauts as part of their standard equipment.) Weaponization of space is out of bounds! Two treaties prevent militarization of space.

Outer Space Treaty

The Outer Space Treaty, considered by the Legal Subcommittee in 1966. Later that year, agreement was reached in the General Assembly. The treaty included the following principles:
the exploration and use of outer space shall be carried out for the benefit and in the interests of all countries and shall be the province of all mankind;
outer space shall be free for exploration and use by all States;
outer space is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means;
States shall not place nuclear weapons or other weapons of mass destruction in orbit or on celestial bodies or station them in outer space in any other manner;
the Moon and other celestial bodies shall be used exclusively for peace
Astronauts shall be regarded as the envoys of mankind;
States shall be responsible for national space activities whether carried out by governmental or non-governmental activities;
States shall be liable for damage caused by their space objects; and
States shall avoid harmful contamination of space and celestial bodies.

In summary, the treaty initiated the banning of signatories' placing of nuclear weapons or any other weapons of mass destruction in orbit of Earth, installing them on the moon or any other celestial body, or to otherwise station them in outer space. The United States, the United Kingdom, and the Soviet Union signed the treaty and it entered into effect on October 10, 1967. As of January 1, 2005, 98 States have ratified, and an additional 27 have signed the Outer Space Treaty.
Note that this treaty does not ban the placement of weapons in space in general, only nuclear weapons and WMD.

Space Preservation Treaty

The Space Preservation Treaty was a proposed 2006 UN General Assembly resolution against all space weapons. Three countries, most notably the United States of America, abstained from voting on most provisions of this treaty [5] because the proposed treaty did not do enough to clearly define what is meant by a "space weapon", and therefore was open to wide interpretation and impossible to verify whether it was being violated.

So No. No weapons of any kind in Space.

not that far.. but the multiple satellite launch technology is a close cousin of an MIRVed ICBM.

Not even close. Atmospheric re-entry of warheads is the main issue concerning MIRVed ICBMs.

Looks like you are right. Foreign Satellites are not counted. So this is counted as 2 missions. This is so confusing. Even Indian can get it wrong.

Even these satellites are not designed by ISRO & launched by single launcher; but at end every satellite need its separate ejection system from vessel, its own telemetry command & needs to put it on its predefined orbit & also integration of so much satellite in single launch platform. So every satellite launch count as a mission in ISRO/INDIA.
Although I count whole as A MISSION, but its on ISRO, how they count their missions.
