Polar Satellite Launch Vehicle is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, commercially available only from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).

Some notable payloads launched by PSLV include India’s first lunar probe Chandrayaan-1, India’s first interplanetary mission, Mars Orbiter Mission (Mangalyaan) and India’s first space observatory, Astrosat.

Why is PSLV important?

PSLV earned its title ‘the Workhorse of ISRO’ through consistently delivering various satellites to Low Earth Orbits, particularly the IRS series of satellites. It can take up to 1,750 kg of payload to Sun-Synchronous Polar Orbits of 600 km altitude.

Does PSLV return to Earth?

ISRO launches PSLV return to flight mission with 31 satellites. ISRO’s Polar Satellite Launch Vehicle lifts off from the Satish Dhawan Space Centre at 10:59 p.m. Eastern Jan.. India’s Polar Satellite Launch Vehicle successfully returned to flight Thursday night.

What is difference between PSLV and GSLV?

DifferencesPSLV is the third generation launch vehicle of India and the first Indian launch vehicle which is equipped with liquid stages. … PSLV is designed mainly to deliver the earth observation or remote sensing satellites, whereas, GSLV has been designed for launching communication satellites.

10 Amazing facts about PSLV C-40

1. ISRO has successfully launched PSLV C-40 which carries the Cartosat-2 Series earth observation Satellite and 30 co-passenger satellites. It was launched from Satish Dhawan Space Centre SHAR, Sriharikota at 9.29 am. PSLV 31 satellites, weighs 1323 kg and deployed in the upper orbit of the Earth after observation.
2. The PSLV-C 40 co-passenger satellite includes 2 satellites from India, while 28 satellites from six countries via Canada, Finland, France, Korea, the United Kingdom and the United States. Do you know that the satellites that the PSLV is carrying is India’s 100th satellite where as Cartosat 2 is a surveillance satellite?
3. Do you know that 19 of the 28 international co-passenger satellites are from America, five from South Korea and one each from Canada, France, Britain and Finland.
4. According to the scientists, this mission is a unique one as the satellites that are to be launched will be in two orbits.

How ISRO will make Indian Railways safe?
5. Cartosat 2 is a monitoring satellite and will be used to monitor the coastal areas and cities. It has a high-resolution camera, which will provide high resolution scene specific spot images.
6. Another interesting fact is Cartosat-2 series (710Kg) was the first to be separated from the rocket and placed into sun synchronous orbit at 505 km above the earth. It also has a co-passenger satellite that includes 100 kilograms of micro satellites and 10 kilograms of nano satellites in different orbits.
7. The 28 International customer satellites are being launched under the commercial agreements between ISRO and Ántrix Corporation Ltd’. This will be the third satellite of the 100th satellite Cartosat-2 series.
8. The mission of Cartosat-2 series will orbit the Earth for a period of five years.
9. Amazing, PSLV rocket of ISRO’s workhorse weighs nearly 320 tonnes and stands up to 44.4 meters which is equivalent to a 15-storey building. Also, the whole process of placing the satellites in two orbits took 2 hours 21 minutes which is the longest so far.
10. PSLV-C 40 is the ISRO’s first space mission of 2018. On 31 August 2017, a similar rocket failed to place the country’s eighth navigation satellite in the Earth’s lower orbit. It maintains one of the largest fleet of communication satellites (INSAT) and IRS satellites.
It would not be wrong to say that ISRO is India’s strongest launching station. It provides services to other countries also. It maintains one of the largest fleet of communication satellites (INSAT) and remote sensing (IRS) satellites to cater the demand for fast and reliable communication and earth observation respectively.
