Parachute deployment tests for Gaganyaan
GS Paper - 3 (Space Technology)
ISRO has successfully conducted a series of tests on drogue parachutes, which would play a pivotal role in stabilising the crew module and reducing its velocity to a safe level during re-entry in the planned Gaganyaan human space flight mission.
More about the Mission
The Gaganyaan mission hopes to safely transport astronauts to Space and back. Drogue parachutes are deployed to decrease speed and stabilise rapidly moving objects.
ISRO's Thiruvananthapuram-based Vikram Sarabhai Space Centre (VSSC) successfully conducted a series of Drogue Parachute Deployment Tests at the Rail Track Rocket Sled (RTRS) facility of the Terminal Ballistics Research Laboratory in Chandigarh during 8-10 August.
The tests were conducted in collaboration with Aerial Delivery Research and Development Establishment (ADRDE)/DRDO.
The drogue parachutes, packed within pyro-based devices known as mortars, are cleverly designed to eject the parachutes into the air upon command.
These conical ribbon-type parachutes, boasting a diameter of 5.8 metres, employ a single-stage reefing mechanism, ingeniously minimising canopy area and mitigating opening shock, ensuring a smooth and controlled descent.
During the three comprehensive tests conducted at the RTRS facility, a range of real-world scenarios were simulated to rigorously evaluate the performance and reliability of the drogue parachutes.
The first test simulated the maximum reefed load, marking a groundbreaking introduction of reefing in a mortar-deployed parachute within India.
The second test emulated the maximum dis-reefed load, while the third test showcased the deployment of the drogue parachute under conditions mirroring the maximum angle of attack experienced by the crew module during its mission.
These successful RTRS tests serve as a critical qualification milestone for the drogue parachutes, confirming their readiness for integration into the upcoming Test Vehicle-D1 mission.
Notably, earlier this year, theRTRS tests of Pilot and Apex cover separation parachutes were also conducted, further accentuating the progress of the Gaganyaan mission's parachute system development.
Theintricate parachute sequence for the Gaganyaan crew module's deceleration system encompasses a total of 10 parachutes.

Russia’s Luna-25 crashes
GS Paper - 3 (Space Technology)
Russia’s Moon mission ended in failure after its spacecraft Luna-25 spun out of control and crashed into the moon, Russian space agency Roscosmos said on 20 August 2023.
What happened to Luna-25?
Luna-25 was supposed to land on the Moon on 21 August 2023, days ahead of India’s Chandrayaan-3. Its intended landing site was close to Chandrayaan-3’s, near the lunar south pole.
The crash was confirmed a day after Roscosmos reported an “abnormal situation” which its specialists were analysing.
The space agency had said on 19 August 2023 that it had lost contact with the aircraft as it was shunted into pre-landing orbit.
On 19 August 2023, in accordance with the flight program of the Luna-25 spacecraft, an impulse was provided for the formation of its pre-landing elliptical orbit.
Communication with the Luna-25 spacecraft was interrupted. The measures taken on 19 and 20 August 2023 to search for the device and get into contact with it did not produce any results. According to the results of the preliminary analysis, due to the deviation of the actual parameters of the impulse from the calculated ones, the device switched to an off-design orbit and ceased to exist as a result of a collision with the lunar surface, Roscosmos said.
The space agency also said, A specially formed interdepartmental commission will deal with the issues of clarifying the reasons for the loss of the Moon [mission].
What was the Luna-25 mission?
Although launched on 10 August 2023, almost a month after Chandrayaan-3’s launch on 14 July, Luna-25 rode on a powerful rocket to reach the lunar orbit in just six days.
It was supposed to land on the lunar South Pole before Chandrayaan-3, and its success would have made Russia the first country to do so. Luna-25’s mission life was for one year, and its lift-off mass was 1,750 kg.
It did not carry a rover, but had eight payloads mainly to study the soil composition, dust particles in the polar exosphere, and most importantly detect surface water on the moon.
Significance
The failure of Luna-25 underlines how tricky soft-landings on the Moon are, and echoes India’s heartbreak of 2019.
Since 1976, there has been just one country, China, which has been successful in getting its spacecraft to soft land on the moon.
It has done that twice, with Chang’e 3 and Chang’e 4. All other attempts in the last ten years, by India, Israel, Japan and now Russia, have remained unsuccessful.
If Chandrayaan-3 is able to land successfully, India would become just the fourth country in the world, after the United States, the erstwhile Soviet Union and China, to have landed a spacecraft on moon, and the first-ever to land close to the lunar south pole.
