The '''PSLV-C44''' was the 46th mission of the Indian [[Polar Satellite Launch Vehicle]] (PSLV) program. It was the first flight of PSLV-DL, having 2 strap-on boosters and placed a primary payload [[Microsat-R]] and a secondary payload of [[Kalamsat|Kalamsat V2]] in [[Sun-synchronous orbit]]s.<ref name="c44">{{cite web|url=https://www.isro.gov.in/update/25-jan-2019/pslv-c44-successfully-launched-microsat-r-and-kalamsat-v2|title=PSLV-C44 successfully launched Microsat-R and Kalamsat-V2|website=isro.gov.in|publisher=ISRO|access-date=2019-01-25}}</ref><br />

The PSLV-C44 was launched from the [[Satish Dhawan Space Centre|First Launch Pad]] (FLP) of the [[Satish Dhawan Space Centre]] in Sriharikota at 11:37:00 P.M. [[Indian Standard Time|IST]] on 24 January 2019, following a 28-hour countdown that began at 07:37 P.M.

The PSLV C-44 rocket had four stages; each one was self-contained, with its own [[Spacecraft propulsion|propulsion system]], thereby capable of functioning independently.<ref name="PSLV-C44 Brochure">{{cite web |url=https://www.isro.gov.in/pslv-c44/pslv-c44-launch-brochure|title=PSLV-C44 Brochure|publisher=ISRO|access-date=24 January 2019}}</ref> The first and third stages used composite solid propellants, while the second and fourth stage used earth-storable liquid propellants.<ref name="PSLV-C42 Brochure"/> It had a lift-off mass of {{cvt|230400|kg}} and measured {{cvt|44.4|m}} in height.<ref name="PSLV-C44 Brochure"/> It carried two satellites built by [[Defence Research and Development Organisation]] (DRDO) and Space Kidz India into orbit, weighing {{cvt|740|kg}} and {{cvt|1.2|kg}} respectively, bringing the total payload mass to {{cvt|741.2|kg}}.<br />
<br />
The satellite [[Microsat-R]] was placed into a lower [[Sun-synchronous orbit]] of {{cvt|274.12|km}} altitude and 96.575° inclination, meanwhile, the second satellite was placed with an experimental 4th stage into an orbit of {{cvt|450|km}} altitude and 98.767°.<ref name="PSLV-C44 Brochure"/> The satellite was launched free of cost and was placed into the orbit after 2 subsequent rocket burn past Microsat-R release.<ref name="c44 page">{{cite web|url=https://www.isro.gov.in/launcher/pslv-c44|title=PSLV C44 Mission|author=ISRO|access-date=13 January 2019|archive-url=https://web.archive.org/web/20190117013408/https://www.isro.gov.in/launcher/pslv-c44|archive-date=17 January 2019|url-status=dead}}</ref><ref name="kamalsat">{{cite web |url=https://economictimes.indiatimes.com/news/science/worlds-lightest-satellite-kalamsat-v2-lifts-off-successfully-from-sriharikota/articleshow/67678694.cms|title=World's lightest satellite 'Kalamsat-V2' lifts-off successfully from Sriharikota|author=Economics Time|access-date=25 January 2019}}</ref><br />
