On August 7, India launched its latest rocket, the small satellite tv for pc launch automobile (SSLV), which sadly failed. The launch, which occurred from the Satish Dhawan House Centre, Sriharikota within the state of Andhra Pradesh in southern India, was carrying two satellites – the Earth statement satellite tv for pc (EOS-02) and AzaadiSAT. EOS-2 is an optical distant sensing satellite tv for pc with a excessive spatial decision, designed and developed by the Indian House Analysis Group (ISRO) with a key goal “to understand and fly an experimental imaging satellite tv for pc with a brief turn-around time and to exhibit launch on demand functionality.” The second satellite tv for pc, AzadiSAT, consisted of an array of 75 tiny payloads, weighing round 50 grams, put collectively by college students, to measure ionizing radiation. 

Quickly after the launch, ISRO Chairman Dr. S Somanath stated that there was a sensor failure or “a logic drawback within the sensor” which resulted within the inserting of the satellites in an elliptical orbit, moderately than a round orbit. Resulting from this failure, the ISRO said that the satellites “are now not usable.” However the ISRO chairman added that apart from the sensor failure, there was no different anomaly and that each new ingredient added within the new SSLV carried out very nicely together with propulsion levels, total {hardware}, its aerodynamic design, the brand new separation system, new era and low-cost management electronics, and your complete structure of the rocket.

ISRO is planning the subsequent developmental flight of the SSLV (SSLV-D2) in November this yr. Though the rocket failed, that every one the brand new components within the SSLV carried out nicely is an achievement by itself, contemplating that this was its maiden launch. As a comparability, notice that India’s first polar satellite tv for pc launch automobile (PSLV) flight, PSLV-D1, in 1993 was additionally a failure however as we speak the PSLV is ISRO’s workhorse launcher. 

SSLV has been a much-awaited rocket, able to launching mini, micro or nano satellites weighing from 10 to 500 kilograms right into a 500 kilometer planar orbit, primarily low earth orbit. The SSLV is four-stage launch automobile, with the three fundamental levels utilizing solid-fueled rocket engines. Insertion of satellites into the meant orbit is completed via a liquid propulsion-based velocity trimming module (VTM). SSLV was conceived as a solution to numerous small satellites launches that in any other case must piggyback on bigger missions, whereas the SSLV gives a extra environment friendly possibility due to its low value, low turn-around time, flexibility to accommodate a number of satellites, launch-on-demand feasibility, and minimal launch infrastructure necessities. The SSLV takes simply three days and 6 folks to combine, not like the PSLVs and different launch autos, which may take 70 days and 60 folks to place collectively — an enormous benefit. 

The ISRO views the SSLV as an possibility not merely for India, but additionally for rocket-launch clients from internationally. Former ISRO Chairman Dr. Ok. Sivan earlier stated that “about 15 to twenty SSLVs could be required yearly to fulfill the nationwide demand alone.” India’s manufacturing of SSLVs via the New House India Ltd, the industrial arm of the ISRO, also can enhance the function and presence of the non-public sector in India’s house sector. India already has a consortium of industries working collectively on the ISRO’s tried and examined launcher, the PSLV. ISRO can presumably replicate the PSLV outsourcing route for the SSLV as nicely, which may increase India’s total house competitiveness. The SSLV will add a brand new functionality for quick launches to India’s house program.

The ISRO has had some failures just lately, however these are usually not uncommon for an area company. Each house company has gone via such phases. Not solely that, the ISRO has been engaged on some pretty complicated missions in the previous couple of years, which partly accounts for these failures. There was vital functionality growth throughout the ISRO because it will get nearer to its Gaganyaan human house mission. Though the ISRO had initially deliberate to launch the Gaganyaan mission in 2022, to coincide with India’s seventy fifth yr of independence, it has now been pushed to 2023 or early 2024.

The truth is, the chairman of ISRO in an interview defined that there are a number of missions but to be achieved and solely after these flight assessments will India’s first human house mission be achieved. Somnath detailed the completely different missions, together with 4 abort missions and two GSLV Mark III unmanned flights, earlier than the Gaganyaan mission. The GSLV Mk III rocket is designed for heavy launch duties and is the designated launch automobile for the Gaganyaan mission. 

Regardless of this and different latest failures, the ISRO seems to be taking a decided however prudent path for the longer term. Thus, the ISRO management has postponed missions equivalent to Gaganyaan moderately than danger a failure that may have human, materials, and reputational prices. There may be little doubt that each on the well-liked and political ranges, the Indian house program retains sturdy help and nationwide dedication.
