• From TERLS, RH200's successful flight took off.
• The PSLV-C54/EOS-06 mission is about to launch, thanks to ISRO.
• The hot test for the CE20 cryogenic engine was successful.

The flexible sounding rocket RH200 of the Indian Space Research Organization (ISRO) registered its 200th consecutive successful launch from the coasts of Thumba, Thiruvananthapuram, on Wednesday, according to ISRO. 

According to the Indian Space Research Organisation, it is a 'historic occasion' (ISRO). Those in attendance were ISRO Chairman S. Somanath and former president Ram Nath Kovind. The successful launch of RH200 took place from the Thumba Equatorial Rocket Launching Station (TERLS). 

According to an ISRO statement, 'Indian sounding rockets are employed as privileged tools for the scientific community to carry out studies on meteorology, astronomy and comparable fields of space physics.' The sounding rocket platform has been used in campaigns like Equatorial ElectroJet (EEJ), Leonid Meteor Shower (LMS), Indian Middle Atmosphere Programme (IMAP). 

According to the national space agency based here, the Rohini Sounding Rocket (RSR) series served as the prototype for ISRO's heavier and more complicated launch vehicles and is still used today for atmospheric and meteorological investigations.

According to the statement, 'the 200th consecutive successful flight provides evidence to the devotion of Indian rocket scientists towards unequalled reliability.' On November 26, ISRO will launch the PSLV-C54/EOS-06 mission from the Sriharikota spaceport with Oceansat-3 and eight micro satellites, including one from Bhutan. 

The national space agency said on Sunday that the launch is scheduled for Saturday at 11.56am. Last week, ISRO revealed that a successful engine test has increased the payload capacity of India's heaviest LVM3 rocket by up to 450 kg. 

The indigenously created CE20 cryogenic engine for Launch Vehicle Mark 3 (LVM3), according to the Indian Space Research Organisation, underwent a successful hot test on November 9 with an increased thrust level of 21.8 tonnes, according to the nation's national space agency.
