  1. ISRO is such an organization which has a large pool of single (Unmarried) scientists who has dedicated their whole life to nation. They work all the time for ISRO without looking at watch and at office time. How many of you know this?

    This is the reason ISRO is able manage very complex mission which would otherwise take many years are completed in few months.

instead of the nano satellite if you install 15 SRE which can easily fit inside the PSLV fearing then it can carry atleast 50 MIRVS

SRE was a space capsule of small size , typically o af warhead size, which entered earth and it was guided.
That wouldn't be required if Agni 6 with MIRV mature.

Pakistan may need it as that dabba abbakadil missile cannot launch MIRv.

Indian Space Research Organisation (ISRO) scripted history today by successfully launching a record 104 satellites, including India's earth observation satellite, on a single rocket from the spaceport in Sriharikota. This is the highest number of satellites ever launched in a single mission.

The space agency's trusted workhorse Polar Satellite Launch Vehicle PSLV-C37, on its 39th mission, took off in the morning, at 9.28 am, today, from Sriharikota space centre with the 104 satellites, of which 101 belongs to international customers.

The first to be let off was India's high resolution Cartosat-2 series satellite made especially to monitor activities of India's hostile neighbours at a resolution of less than a metre keeping a bird's eye view on both Pakistan and China.

As the scientists at the Mission Control centre broke into cheers, Indian Space Research Organisation (ISRO) Chairman A S Kiran Kumar announced: "All 104 satellites successfully placed in orbit. My hearty congratulations to the entire ISRO team for the wonderful job they have done."

"This is a significant step for India. This entire launch will last for 28 minutes...It is a four stage mission. The first satellite will go in the 17 th minute followed soon by two nano satellites by India. Later 96 satellites will be placed in their orbits," said Ajay Lele of ISRO.

The two Indian nano-satellites are ISRO's INS-1A and INS-1B. INS-1A and INS-1B which carry a total of four different payloads from Space Applications Centre (SAC) and Laboratory for Electro Optics Systems (LEOS) of ISRO for conducting various experiments.

The launch was closely watched by ISRO chairman AS Kiran Kumar and other top scientists from the mission control centre at Sriharikota.

The countdown for the launch of PSLV-C37/Cartosat2 Series satellite mission began at 5:28 AM yesterday soon after the Mission Readiness Review committee and Launch Authorisation Board gave its approval for lift off, after which scientists commenced filling of the propellant for the rocket, ISRO said.

The PSLV-XL variant rocket, standing 44.4 metre tall and weighing 320 ton, tore into the morning skies at 9.28 a.m. with a deep throated growl breaking free of the earth's gravitational pull.

What is significant about the launch is the number of satellites carried by a rocket. Compared to successful launch by the Russian Space Agency launching 37 satellites in one go, India became the first country to script history by launching 104 satellites in a single rocket.

Prime Minister Narendra Modi and President Pranab Mukherjee congratulated Team ISRO for the successful launch.

Congratulations to @isro for the successful launch of PSLV-C37 and CARTOSAT satellite together with 103 nano satellites!

10:05 AM - 15 Feb 2017



It was a significant achievement for ISRO as last time it had launched 23 satellites in one go in June 2015.

PSLV first launched the 714 kg CARTOSAT-2 Series satellite for earth observation, followed by 103 co-passenger satellites, together weighing about 664 kg at lift-off into polar Sun Synchronous Orbit, about 520 km from Earth.

ISRO scientists have used the XL Variant -- the most powerful rocket -- earlier used in the ambitious Chandrayaan and during the Mars Orbiter Mission (MOM).

Of 101 co-passenger satellites, 96 belong to USA, five from International customers of ISRO -- Israel, Kazakhstan, Netherlands, Switzerland, United Arab Emirates, respectively.

Two other Indian nano satellites, totally weighing about 1,378 kg, will also ride piggyback in the rocket

The nano-satellites belonging to international customers are being launched as part of the arrangement by Antrix Corporation Ltd (ANTRIX) the commercial arm of the ISRO.


Cartosat-2 Series, which is the primary satellite, will be similar to the earlier four satellites in Cartosat-2 Series.

After coming into operation, it will provide remote sensing services.Images sent by it will be useful for coastal land use and regulation, road network monitoring, distribution of water and creation of land use maps, among others.
Cartosat-2 Series has a mission life of five years.

The two Indian Nano-satellites INS-1A and INS-1B were developed as co-passenger satellites to accompany bigger satellites on PSLV.

The primary objective of INS (ISRO Nano Satellite) is to provide an opportunity for ISRO technology demonstration payloads, provide a standard bus for launch on demand services.

INS-1A carries Surface Bidirectional Reflectance Distribution Function Radiometer and INS-1B caries Earth Exosphere Lyman Alpha Analyser as payloads.

PLANET LAUNCHES SATELLITE CONSTELLATION TO IMAGE THE WHOLE PLANET DAILY

February 14, 2017, 19:58 PST

Today Planet successfully launched 88 Dove satellites to orbit—the largest satellite constellation ever to reach orbit. This is not just a launch (or a world record, for that matter!); for our team this is a major milestone. With these satellites in orbit, Planet will reach its Mission 1: the ability to image all of Earth’s landmass every day.

Tonight is the culmination of a huge effort over the past 5 years. In 2011 we set ourselves the audacious mission of imaging the entire Earth land area every day. We were convinced that armed with such data, humanity would be able to have a significant positive impact on many of the world’s greatest challenges. We calculated that it would take between 100-150 satellites to achieve this, and we started building them. After today’s launch, Planet operates 144 satellites in orbit. We have reached our milestone.

It’s taken a minor Apollo project to get here! Behind the scenes we’ve miniaturized satellites; learned how to manufacture them at scale; constructed the world’s second largest private network of ground stations; custom built an automated mission control system; created a massive data pipeline able to process the vast amount of imagery we collect; and developed a software platform that lets customers, researchers, governments and NGOs access imagery quickly. Each of these has been a significant undertaking in and of itself—and together it represents a major systems engineering project. This is not to mention the non-engineering efforts from raising capital, receiving regulatory licenses, booking launches, and building a base of hundreds of partners that use the data to solve their needs.

Without a doubt, the single largest driver behind this record-breaking success is the unrelenting dedication of the Planet team. We’ve been humbled by them for the last five years and we thank them today.

Next up: getting this data to our customers and to those who need it the most! But for now Planet is having a great start to the year worthy of a little celebration.

—Will & Robbie

. . . . . . . . . . . .

Here are some additional facts and figures regarding this launch:

The 88 Dove satellites (collectively known as “Flock 3p”) rode aboard a PSLV rocket from the Satish Dhawan Space Centre in Sriharikota, India

This leads to two world records: a record for the most satellites ever launched on a single rocket; and a record for the largest private satellite constellation in history, totaling 149 satellites in all

This is our 15th launch of Dove satellites and second aboard India’s PSLV. The launch of Flock 3p comes off the successful launch of Flock 2p on the PSLV in June 2016

After deployment, all 88 satellites will be autonomously commissioned in batches. We expect Flock 3p to enter normal imaging operations in about three months

Each of the Flock 3p satellites—our 13th build—sports a 200 mbps downlink speed and is capable of collecting over 2 million km² per day

India has created history by successfully launching 104 satellites on a single mission, overtaking the previous record of 37 satellites launched by Russia in 2014.

All but three of the satellites are from foreign countries, most of them from the United States.

The launch took place from the Sriharikota space centre in east India.

Observers say it is a sign that India is emerging as a major player in the multi-billion dollar space market.

"This is a great moment for each and every one of us. Today we have created history," project director B Jayakumar was quoted as saying by the Reuters news agency.

Why India's commercial space programme is thriving

Of the 104 small satellites, 96 belong to the United States while Israel, Kazakhstan, the United Arab Emirates, Switzerland and the Netherlands are the other foreign clients.

An Indian cartographic satellite, believed to be capable of taking high resolution images is also on board. It is expected to be used to monitor regional arch rivals Pakistan and China.

The BBC's Sanjoy Majumder in Delhi says the successful launch is yet another feather in the cap of India's ambitious space programme that has earned a reputation of offering a reliable low cost alternative to existing international players.

The Indian government has increased the budget for its space programme this year and also announced plans to send a mission to Venus.

Over the past two decades, India has become a key player in the lucrative commercial space market offering a low-cost alternative.

Isro creates history, launches 104 satellites in one go
Isro's Polar Satellite Launch Vehicle (PSLV) in a single mission.

PSLV-C37carrying the 104 satellites lifted off from the first launch pad at Satish Dhawan Space Centre in Sriharikota at 9.28am. It was PSLV's 39th flightSeventeen minutes later, the rocket started placing the satellites into orbit, one by one with a time-frame of about 11 minutes.

Out of the total 104 satellites placed in orbit, 101 satellites belonged to six foreign countries. They included 96 from the US and one each from Israel, the UAE, the Netherlands, Switzerland and Kazakhstan.

PSLV first injected its main payload Cartosat- 2 series, India's indigenously built earth observation satellite. It was followed by two other nanosatellites of Isro ---- INS-1A and INS-1B.
It then took less than 10 minutes for the rocket to spew out 101 passengers, which are all foreign nanosatellites, as it travelled up in altitude reaching the polar sun synchronous orbit.

Russian Space Agency held a record of launching 37 satellites in one go during its mission in June 2014. India previously launched 23 satellites in a single mission in June 2015.

Isro chairman A S Kiran Kumar congratulated his team for the successful launch of 104 satellites. "My hearty congratulations to the team. The Prime Minister has conveyed his congratulations," he said.

Expect more tons from Isro

Director, Isro Satellite Centre Mayilsamy Annadurai said, "We can also hit centuries like our cricketers. In another three months, we are planning another mission to launch 100 satellites. Besides GSLV missions, we have get Chandrayan - 2 ready for launch next year."

Mission director B Jayakumar said the launch involved complex issues in management and maneuvering, "A great moment for each and every one of us. We have so far launched 226 satellites including 179 foreign satellites," he said.

Director of the Vikram Sarabhai Space Centre K Sivan said it was the toughest mission they had handled. "We had to ensure they don't collide," he said.

"Last year we saw nine successful launches. This year began with a remarkable event. Congratulations to customers on placing confidence on Isro's PSLV," said director of Satish Dhawan Space Centre P Kunhikrishnan.

All about104 satellites

Equipped with panchromatic and multispectral cameras, the 664kg Cartosat -2 will provide remote sensing services similar to that of its predecessors.

Images from the satellite will be used for cartographic applications, urban and rural applications, coastal land use and regulation, utility management like road network monitoring, water distribution, creation of land use maps, change detection to bring out geographical and manmade features and various other land information system (LIS) and geographical information system (GSI) applications.

INS-1A and INS-1B are versatile and modular nanosatellite bus system envisioned for future science and experimental payload.

Among the foreign satellites, 88 cube satellites belonged to San Francisco-based earth imaging startup Planet. With the launch, the company has increased its fleet to 143 satellites whichwill soon begin capturing images of the earth's entire landmass, including India, every day.

Eight other satellitesbelonging to Spire Global, US, will provide services for vessel tracking and weather measurement.

The nanosatellites from Israel, Kazakhstan, the Netherlands, Switzerland and the UAE are mostly technology demonstrators.

As usual PDF chinese troll beast trying to prove that putting 104 satellites in orbit is not a bi thing.
Chinese are well aware of our capabilities and are only downplaying it. While porkies are idiots who don't know even ABC of technology, this same technology is used to make MIRV capable missiles, porkistan should know had this rocket contained nukes there would have been no Pakistan by now.

One thing cartosat-2 have a repeat interval of 4 days.....that very big time gap.
Meanwhile those 88 nano satellites had a repeat interval of 24 hours only.
