Chennai: A 27-hour countdown began Sunday for the launch of India’s EMISAT satellite along with 28 nano satellites of global customers from Sriharikota on Monday, a mission which would witness the ISRO placing payloads in three orbits and conducting space experiments for the first time.

The EMISAT satellite is aimed at electromagnetic measurement.

The countdown began at 6.27 am for the launch on board Indian Space Research Organisation’s third generation workhorse Polar Satellite Launch Vehicle (PSLV), in its 47th flight, ISRO said.

The four-stage PSLV-C45 will blast off from the second launch pad at the spaceport of Sriharikota, about 125 kms from here, at 9.27 AM Monday, agency officials said.

The mission will mark several firsts to the credit of the space agency as it would manoeuvre satellites in various orbits and orbital experiments including on maritime satellite applications.

According to ISRO, a new variant of the rocket PSLV-QL equipped with four Strap-On motors in the first stage is used for the launch.

PSLV, also used in India’s two key missions — “Chandrayan” in 2008 and Mars Orbiter in 2013, is a reliable and versatile launch vehicle for ISRO with 39 consecutive successful flights till June, 2017 and five-in-a row from January 2018.

The rocket has encountered only two failures so far — its maiden developmental flight ended unsuccessful way back in 1993. In September, 2017 the flight went off without any hitch but the IRNSS-1H Satellite could not be released into orbit after the PSLV-C39’s heat shield failed to open on reaching the orbit.

In Monday’s mission, ISRO scientists would place the satellites and payloads in three different orbits, a first for the agency.

After injecting the 436 kg primary satellite EMISAT, intended for electromagnetic spectrum measurement, at around 17 minutes from lift off in a 749 km orbit, they would restart the fourth stage again.

During this initiative, all the other 28 customer satellites, totally weighing about 220 kgs, would be released by lowering the fourth state to around 504 kms orbit.

 

India’s EMISAT satellite PSLV-C45 along with 28 other to get into orbit for first time by ISRO:

 

Again, the fourth stage would be reignited and further lowered to 485 kms orbit to serve as an orbital platform for carrying out space borne experimentations for the first time in ISRO’s history.

According to ISRO, this is the first time it has been envisaged to provide a micro-gravity environment for research organisations and academic institutes to perform experiments.

The PS4-fourth stage hosts three payloads in this mission.

They are automatic identification system from ISRO for Maritime satellite applications capturing messages transmitted from ships.

Automatic Packet Repeating System from AMSAT (Radio Amateur Satellite Corporation), India to assist amateur radio operators in tracking and monitoring position data.

Advanced Retarding Potential Analyzer for lonospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) for the structural and composition studies of ionosphere.

The other 28 international satellites — 25 3U type, two 6U type and one 2U type nano satellites — are from Lithuania (two), Spain (1), Switzerland (1) and the United States (24).

All these satellites are being launched under commercial arrangements, ISRO said.

The previous launches by ISRO this year include the imaging satellite Microsat-R for military purpose along with 1.2 kg Kalamsat in January onboard PSLV-C44.

In February, ISRO launched India’s communication satellite GSAT-31 from the European launch service provider Ariane from French Guiana.

By

New Delhi: Aam Aadmi Party (AAP) has inked a deal with Indian Political Action Committee (IPAC) for image makeover, the party chief Arvind Kejriwal announced on Saturday.

The AAP had secured 67 out of 70 assembly seats in Delhi in the last assembly elections in 2014. The date of assembly election in Delhi is to be announced soon as the poll needs to be completed by February 14, 2020.

Political strategist and currently an influential leader of the Janata Dal (United), Prashant Kishor runs advocacy group IPAC.

The advocacy group also declared on Saturday they have inked a deal with Kejriwal’s party.

On social media platforms, Kejriwal said: “Happy to share that IPAC is coming on-board with us. Welcome aboard!”

The advocacy group also said: “After Punjab results, we acknowledged you as the toughest opponent that we have ever faced. Happy to join forces now with Arvind Kejriwal and Aam Aadmi Party.”

Kishore worked with the Congress in 2017 for Punjab and Uttar Pradesh assembly elections. His wrote a successful story in Punjab in helping the Congress come back to power after two successive electoral losses.

Currently, Kishor is national vice-president of the JD(U) led by Nitish Kumar. JD(U) is an ally of the BJP at Centre as well in Bihar.
