ISRO’s Reusable Launch Vehicle (RLV) Programme

  • Recently, the Indian Space Research Organisation (ISRO) informed that it is all set to carry out the third and final RLV Landing Experiment (RLV LEX) under the Reusable Launch Vehicle (RLV) Programme.
  • RLV-LEX missions involve taking an unmanned winged prototype, christened Pushpak, to a designated height and releasing it to land safely under varying conditions.
  • The configuration of RLV-TD is similar to that of an aircraft and combines the complexity ofboth launch vehicles and aircraft.
  • The winged RLV-TD has been configured to act as a flying test bed to evaluate various technologies, namely, hypersonic flight, autonomous landing, and powered cruise flight.
  • In the future, this vehicle aims to be scaled up to become thefirst stage of India’s reusable two-stage orbital launch vehicle.

Third and Final RLV LEX
– The unmanned winged prototype, christened Pushpak, will be carried to a height of 4.5 km and 500 metres to one side of the runway using an IAF Chinook helicopter and released.
a. The LEX-01 and LEX-02 were carried out successfully in early 2023 and 2024 respectively.
– It aims to look at how the sink rate, or the rate of descent, can be cut down to reduce the impact load. It will also have on board a real-time kinematics (RTK) package.
– It is a more challenging mission compared to the second one, where the altitude was the same but the lateral distance from the runway was 150 metres.
– Another challenge before the upcoming mission is handling tailwind conditions.

Significance of the Experiment

  • It marked a significant milestone in ISRO’s journey towards achieving low-cost access to space. The successful execution of the landing experiment demonstrated ISRO’s capability to develop a reusable launch vehicle, which is expected to significantly reduce the cost of launching satellites into orbit.
  • The RLV-TD programmeis a testament to ISRO’s commitment to innovation and technological advancement. With the successful completion of this landing experiment, ISRO has moved one step closer to realising its vision of developing a fully reusable launch vehicle.
  • After the successful completion of the RLV-LEX series, ISRO plans to proceed with the next stage of tests under the RLV-TD Programme, involving an unmanned Orbital Re-entry Vehicle (ORV)that is 1.6 times the size of ‘Pushpak’ used in the LEX missions.
    • The ORV will be placed in a 400-kilometre orbit around Earth using a modified Geosynchronous Satellite Launch Vehicle (GSLV)

Reusable Launch Vehicle (RLV) Technology

– It is being explored by several countries and organisations like the Japan Aerospace Exploration Agency (JAXA), the United Launch Alliance (ULA), and the European Space Agency (ESA), along with the ISRO.

Global Demonstration

– NASA: Reusable space vehicles have been in existence for a long time with NASA space shuttles carrying out dozens of human space flight missions.
– SpaceX: The use case for reusable space launch vehicles has revived with the private space launch services provider SpaceX demonstrating partially reusable launch systems with its Falcon 9 and Falcon Heavy rockets since 2017.
a. SpaceX is also working on a fully reusable launch vehicle system called Starship.

    • Resistant bacteria keep a higher growth rate during incubation, while susceptible ones grow slowly or lyse.
  • It provides targeted antibiotic treatmentin less than one hour, reducing the risk of AMR.
  • It has been evaluated with the most common uropathogenic bacterial speciesin uncomplicated UTI:
    • Gram negative: Escherichia coli, Klebsiella pneumonia, Proteus mirabilis;
    • Gram positive:Staphylococcus saprophyticus, Enterococcus faecalis;

Longitude Prize on Antimicrobial Resistance (AMR)

Urinary Tract Infections (UTI)

– These are one of the most common bacterial infections and also one of the driving causes of antibiotic prescription worldwide.
– Bacteria in the urine are trapped in over 10,000 microfluidic traps in parallel arrays and exposed to five different antibiotics at five different concentrations.
– Five commonly prescribed antibiotics for the treatment of uncomplicated UTI are tested: amoxicillin/clavulanic acid, ciprofloxacin, fosfomycin, nitrofurantoin and trimethoprim.
– Due to the limited availability of point-of-care diagnostics, empiric treatment is standard in many settings.
a. Due to the high incidence of the disease, empiric UTI treatment fuels antimicrobial resistance (AMR).

Do You Know?

– Antibiotic-resistant infections killed nearly 1.3 million people globally in 2019 and are on course to cause 10 million deaths a year by 2050outstripping deaths caused by cancer.
– The global economy may lose up to 4 trillions by 2030 and up to 100 trillions by 2050 due to the AMR crisis.
