ISRO aces final test of Reusable Launch Vehicle tech for Landing Experiment

Published

on

New Delhi, June 23 (IANS) The Indian Space Research Organisation (ISRO) on Sunday announced success in the final test of the Reusable Launch Vehicle (RLV) Landing EXperiment (LEX).

This is the third consecutive success in the series of LEX (03) technology demonstrating “the autonomous landing capability” and was conducted at 07:10 a.m. at the Aeronautical Test Range (ATR) in Chitradurga, Karnataka.

But, the RLV LEX-03 mission achieved success “under more challenging release conditions (cross range of 500 m against 150 m for LEX-02) and more severe wind conditions,” ISRO said in a statement.

As part of the experiment, the winged vehicle, named ‘Pushpak’, was released from an Indian Air Force Chinook Helicopter at an altitude of 4.5 km.

Armed with advanced autonomous capabilities, “Pushpak executed a precise horizontal landing under challenging conditions,” ISRO said.

The space agency added that “from a release point 4.5 km away from the runway, Pushpak autonomously executed cross-range correction manoeuvres, approached the runway, and performed a precise horizontal landing at the runway centreline”.

“Due to this vehicle’s low lift-to-drag ratio aerodynamic configuration, the landing velocity exceeded 320 kmph, compared to 260 kmph for a commercial aircraft and 280 kmph for a typical fighter aircraft”.

ISRO stated that post-touchdown, brake parachutes were used to reduce the vehicle velocity to nearly 100 kmph. Then landing gear brakes were used to decelerate and stop the vehicle on the runway.

The RLV-LEX mission, which uses multisensor fusion including sensors like an inertial sensor, radar altimeter, flush air data system, pseudo lite system, and NavIC, “simulated the approach and landing interface and high-speed landing conditions for a vehicle returning from space”.

ISRO noted that the winged body and flight systems were reused without any modification from the LEX-02 mission, demonstrating the robustness of ISRO’s capability of design to reuse flight systems for multiple missions.

Further, the success validates “the advanced guidance algorithm catering to longitudinal and lateral plane error corrections — essential for the future Orbital Reentry Mission”.

New Delhi, July 3 (IANS) Indian startups have raised nearly $7 billion in funding during the first half (H1) of 2024, more than the $5.92 billion raised in H1 2023.

However, the figures are still far less than $20 billion in H1 2022, according to data compiled by TheKredible.

The $7 billion funding included 182 growth or late-stage deals worth $5.4 billion and 404 early-stage deals worth $1.54 billion. About 99 were undisclosed deals, reports Entrackr.

During H1, Indian startups produced a couple of unicorns — Perfios and Krutrim SI Designs. Last year, only two startups managed to cross the unicorn valuation while 2022 and 2021 witnessed the emergence of 26 and 44 unicorns, respectively.

When it comes to month-on-month trends, June witnessed nearly $2 billion in funding which is more than double the average of $1 billion monthly funding until May this year, the report mentioned.

Late-stage companies such as Zepto, Flipkart, PharmEasy and Lenskart topped with $665 million, $350 million, $216 million, and $200 million funding, respectively.

Moreover, H1 2024 saw 55 mergers and acquisitions, which is lower when compared to 2023. The year 2021 witnessed over 250 mergers and acquisitions which dropped to 204 in 2022 and further reduced to 145 in 2023.

Segment-wise, e-commerce topped the list with 124 startups raising more than $1.87 billion. Fintech, healthtech, SaaS and EV startups were next on the list. Amount-wise, EV startups secured more funding than SaaS and healthtech. Agritech, foodtech, edtech and proptech saw a decline in funding during H1 2024.

Published

By

New Delhi, July 3 (IANS) Amid the rise in Zika virus cases in Pune, the Centre, on Wednesday, issued an advisory to all states asking them to step up vigil.

Zika virus disease (ZVD) is a mosquito-borne disease transmitted by Aedes mosquitoes. While it is usually mild to moderate disease in adults and requires no specific treatment, in pregnant women, it may cause microcephaly — a condition in which the head is significantly smaller due to abnormal brain development — in the foetus.

Maharashtra has reported eight cases of Zika virus till July 2. Of these, six are from Pune, one each from Kolhapur and Sangamner, and 2 are pregnant women.

“In view of some reported cases of Zika virus from Maharashtra, Dr Atul Goel, Director General of Health Services (DGHS), has issued an advisory to states highlighting the need for maintaining a state of constant vigil over the Zika virus situation in the country,” the Health Ministry said.

The ministry urged states “to instruct the health facilities in the affected areas or those catering cases from affected areas to screen the pregnant women for Zika virus infection.”

The health workers must also “monitor the growth of the foetus” of Zika-positive women and “act as per Central government guidelines,” the ministry said.

It also asked health facilities and hospitals to identify a nodal officer to monitor and act to keep the premises free of Aedes mosquitoes.

Besides, the advisory called on states to “strengthen entomological surveillance and intensify vector control activities in residential areas, workplaces, schools, construction sites, institutions, and health facilities.”

Currently, Zika testing facilities are available at the National Institute of Virology (NIV), Pune; the National Centre for Disease Control (NCDC), Delhi; and a few selected virus research and diagnostic laboratories of the Indian Council of Medical Research (ICMR).

The ministry will continue to monitor the situation closely, the advisory noted.
