The Indian Space Research Organisation (ISRO) on Wednesday launched record number of 104 satellites at one go, in a historic moment for India. With this launch, India has scripted history by becoming the first country to launch more than 100 satellites under single mission.
On Tuesday, the Mission Readiness Review committee and Launch Authorisation Board gave its go ahead for the launch. The 104 satellites were carried by ISRO's workhorse Polar Satellite Launch Vehicle PSLV-C37, which is on its 39th mission.
As it happened:

PSLV-C37 / Cartosat -2 Series Mission Successfully Launched all 104 Satellites: ISRO
#10:00 AM
Separation of all 104 satellites confirmed, record success for ISRO
#9.54 AM
The flock of 88 ‘Dove’ satellites, owned by San Francisco-based Planet, are currently being separated from the rocket. The satellites will be used to provide high-detailed imagery of the earth’s surface.
#9:45 AM
PSLV-C37 successfully places in orbit India's CARTOSAT2 series satellite and 4 other satellites
#9.45 AM
The rocket engine goes off. Orbit achieved. Cartostat-2 satellite ejected. Next, the nano satellites will be separated in sequence. The mission control applauds.
#9.40 AM
The C-37 rocket is currently over seven minutes into its flight and has attained an altitude of over 500 km.
#9.36 AM:
Fourth stage of the mission commences. Both engines performing as expected
#9:29 AM
#9:28 AM
ISRO launches record 104 satellites at one go on PSLV C37 rocket
#9:26 AM
Countdown - 3 minutes to go
#9:00 AM
Preparations underway for mega launch, watch here
#8:35 AM
#8:33 AM
The launch of PSLV-C37/Cartosat-2 Series along with 103 co-passenger satellite can be witnessed live from Sriharikota on Feb 15,2017, beginning at 9:00 hrs a.m (India time).
#8:32 AM
The launch will be telecasted live on Doordarshan and webcast on ISRO's website from 09:00 hrs onwards.
#8:31 AM
The satellites will be blasted off from the SDSC SHAR Sriharikota, Andhra Pradesh at 9:20am.
This launch is significant for India because it is a record-breaking feat for the country. Also, ISRO has achieved this feat after the launch of 23 satellites in one go in June 2015.

PSLV first launched the 714 kg CARTOSAT-2 Series satellite for earth observation, be followed by the injection of 103 co-passenger satellites, together weighing about 664 kg at lift-off into polar Sun Synchronous Orbit, about 520 km from Earth.
The XL Variant, the most powerful rocket, which was used in the ambitious Chandrayaan and during the Mars Orbiter Mission (MOM) has been used by ISRO scientists this time too.
While 96 co-passenger satellites belong to USA, five from International customers of ISRO — Israel, Kazakhstan, Netherlands, Switzerland, United Arab Emirates, respectively.

Two other Indian nano satellites, together weighing about 1,378 kg, were also carried by the rocked. Antrix Corporation Ltd (ANTRIX) the commercial arm of the ISRO made arrangements for the nano-satellites belonging to international customers.
Cartosat-2 Series, which is the primary satellite, is similar to the earlier four satellites in Cartosat-2 Series. Cartosat-2 Series has a mission life of five years.
It will provide remote sensing services after coming into operation. 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.

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.
