Space-tech start-up @AgnikulCosmos today said it has established India’s first launchpad designed and operated by a private player. The facility, situated at Sriharikota, was inaugurated by Isro chairman S Somanath on Nov 25. 1/n
The facility which was designed by Agnikul and executed with support from Isro and Indian National Space Promotion and Authorization Center (IN-SPACe) has two sections to it — the Agnikul launchpad (ALP) and the Agnikul mission control centre (AMCC). 2/n
“Critical systems connecting these two sections, which are 4km away from each other are redundant to ensure 100% operationality during countdown… 3/n
…The launchpad is specifically built keeping in mind the ability to support liquid stage controlled launches, while also addressing the need for Isro’s range operations team to monitor key flight safety parameters during launches,” Agnikul said in a statement issued here. 4/n
Additionally, it has the ability to, as necessary, share data and other critical information with Isro’s mission control centre. 5/n
Agnikul’s first launch, which will be a controlled-and-guided mission, having a vertical launch, using its patented engine will happen from this launchpad. The mission would be a technology demonstrator that will mirror Agnikul’s orbital launch but at a reduced scale. 6/n
“Agnibaan is a highly customizable, 2-stage launch vehicle, capable of taking up to 100kg payload to orbits around 700km high (low Earth orbits) and enables plug-and-play configuration… 7/n
…Agnilet is the world's first single-piece 3D-printed engine fully designed and manufactured in India and was successfully test-fired in early 2021 & became the first company in the country to test its engines at Isro,” the firm said. 8/n
Somanath was quoted as having said that the first exclusive launchpad for a private launch vehicle has come up at Satish Dhawan Space Center (SDSC). 9/n
“Now India can travel to space from one more space platform. Thanks to Agnikul,” Somanath added. 10/n
Agnikul’s co-founder and CEO Srinath Ravichandran said the ability to launch from our own launchpad while still working with ISRO’s launch operations teams is a privilege that we have been granted by @isro and @INSPACeIND. 11/n
“I am deeply grateful to them for the same. It is dream come true for all of us at Agnikul to launch our vehicles from a facility we have designed and built ourselves,” he said. 12/n
Moin SPM, Co-founder, Agnikul said: “We never imagined to have Agnikul’s launchpad (ALP) inside Sriharikota for our launches and this has only been possible with the consistent support of ISRO and IN-SPACe… 13/n
…The new reforms that have been brought in by the Dept. of Space truly accommodate everyone’s dream of going to space.” n/n

Today, @RRI_Bangalore (in pic) said in a first-of-its-kind work, using data from an Indian telescope, scientists have determined properties of radio luminous galaxies formed just 200-mn yrs after #BigBang — a period known as #CosmicDawn. 1/n Image
Pointing out that telescopes, both ground and space-based, are aiming to capture faint signals from the depths of the cosmos to better the understanding of our Universe, RRI said they used the Shaped Antenna measurement of the background RAdio Spectrum-3 (#SARAS3) telescope. 2/n
For the study, SARAS-3, indigenously designed and built at RRI, was deployed over Dandiganahalli Lake and Sharavathi backwaters, located in Karnataka, in early 2020 (see pic). 3/n Image

#Update Been under the weather the last couple of days. Another weekend, another key launch. A 3-in-1 mission for @isro on Nov 26: #PSLVC54 to launch 7 commercial, one diplomatic & 1 main national satellites. 

#Thread to put things in one place, I may not be around tomorrow: 1/n
Last Friday, a private single-stage rocket became the first non-Isro launch vehicle to ever enter the space agency’s spaceport in Sriharikota, which already boasts of 620 launch missions, including sounding rockets (see image/doesn’t include #VikramS). 2/n
This Saturday, the main payload is a satellite for national objectives designed and developed for ocean studies, the Oceansat-3 or Earth observation Satellite-06 (EOS-06). This is part of a series of satellites from Isro dedicated to oceanography and atmospheric studies. 3/n

Space startup @BellatrixAero today opened a new facility in Bengaluru that would expedite the firm's prototyping and rolling out of new models, supplementing its testing lab incubated at the @iiscbangalore. 1/n Image
This facility is part of the company’s expansion plans that will also see a $76-million manufacturing facility come up near @BLRAirport by the end of next year. I first reported that Bellatrix signed an MoU regarding this ($76-mn) facility with the state government. 2/n
The new facility was inaugurated by @isro chairman S Somanath, who visited the firm’s IISc lab before inaugurating this. Somanath expressed confidence that private sector firms like Bellatrix could address some key challenges in the Space sector and complement Isro. 3/n Image

#Space #UPDATE #Thread

Earth observation satellite by @PixxelSpace #Anand will be among seven satellites @NSIL_India will launch as ride-sharing payloads along with @isro’s #Oceansat3, tentatively scheduled to be launched on a #PSLVC54 on Nov 26. 1/n

Pic for representation Image
Anand will be the first privately developed Earth observation satellite to be launched from India and second from the Pixxel stable. 2/n
The firm had launched Shakuntala using a SpaceX rocket in April 2022. Aside from Anand, NSIL will launch two private communication satellites (Thybolt) for Dhruva Space and four other satellites (Astrocast) for US firm Spaceflight. 3/n

#UPDATE #Rockets #Thread

Late yesterday, @isro said that the CE20 cryogenic engine indigenously developed for #LVM3 (#GSLVMk3) has been successfully hot-tested “at an uprated thrust level of 21.8 t for the first time”. 1/n Image
“This will enhance #LVM3 payload capability up to 450kg with additional propellant loading. Major modifications carried out on this test article compared to previous engines was introduction of Thrust Control Valve (TCV) for thrust control,” Isro said. 2/n
Additionally, the space agency said a 3D-printed LOX (liquid oxygen) and LH2 (liquid hydrogen) turbine exhaust casings were inducted in the engine for the first time. 3/n
