Russia’s first moon mission in 47 years failed when its Luna-25 spacecraft spun out of control and crashed into the moon after a problem preparing for pre-landing orbit, underscoring the post-Soviet decline of a once mighty space programme.

Russia’s state space corporation, Roskosmos, said it had lost contact with the craft at 11:57 GMT (5:27pm IST) on Saturday after a problem as the craft was shunted into pre-landing orbit. A soft landing had been planned for Monday.

“The apparatus moved into an unpredictable orbit and ceased to exist as a result of a collision with the surface of the Moon,” Roskosmos said in a statement.

It said a special inter-departmental commission had been formed to investigate the reasons behind the loss of the Luna-25 craft, whose mission had raised hopes in Moscow that Russia was returning to the big power moon race.

The failure underscored the decline of Russia’s space power since the glory days of Cold War competition when Moscow was the first to launch a satellite to orbit the Earth – Sputnik 1, in 1957 – and Soviet cosmonaut Yuri Gagarin became the first man to travel into space in 1961.

It also comes as Russia’s $2 trillion (roughly Rs. 1,66,18,000 crore) economy faces its biggest external challenge for decades: the pressure of both Western sanctions and fighting the biggest land war in Europe since World War Two.

Though moon missions are fiendishly difficult, and many US and Soviet attempts have failed, Russia had not attempted a moon mission since Luna-24 in 1976, when Communist leader Leonid Brezhnev ruled the Kremlin.

Russian state television put news of the loss of Luna-25 at number 8 in its line up at noon and gave it just 26 seconds of coverage, after a news about fires on Tenerife and a 4 minute item about a professional holiday for Russian pilots and crews.

Failed Moonshot

Russia has been racing against India, whose Chandrayaan-3 spacecraft is scheduled to land on the moon’s south pole this week, and more broadly against China and the United States which both have advanced lunar ambitions.

As news of the Luna-25 failure broke, the Indian Space Research Organisation (ISRO) posted on X, formerly Twitter, that Chandrayaan-3 was set to land on August 23.

Russian officials had hoped that the Luna-25 mission would show Russia can compete with the superpowers in space despite its post-Soviet decline and the vast cost of the Ukraine war.

“The flight control system was a vulnerable area, which had to go through many fixes,” said Anatoly Zak, the creator and publisher of www.RussianSpaceWeb.com which tracks Russian space programmes.

Zak said Russia had also gone for the much more ambitious moon landing before undertaking a simpler orbital mission – the usual practice for the Soviet Union, the United States, China and India.

While Luna-25 went beyond the earth’s orbit – unlike the failed 2011 Fobos-Grunt mission to one of the moons of Mars – the crash could impact Russia’s moon programme, which envisages several more missions over coming years including a possible joint effort with China.

Russian scientists have repeatedly complained that the space programme has been weakened by poor managers who are keen for unrealistic vanity space projects, corruption and a decline in the rigour of Russia’s post-Soviet scientific education system.

“It is so sad that it was not possible to land the apparatus,” said Mikhail Marov, a leading Soviet physicist and astronomer.

Marov, 90, was hospitalised in Moscow after news of the failure of Luna-25 was announced, although details of what he was ill with were not available.

Marov told the Moskovsky Komsomolets newspaper that he hoped the reasons behind the crash would be discussed and examined rigorously.

“This was perhaps the last hope for me to see a revival of our lunar program,” he said.

ISRO Postpones Docking of SpaDeX Satellites Again

The Indian Space Research Organisation (ISRO) has postponed its Space Docking Experiment (SpaDex) mission which was scheduled for Thursday, after the satellites drifted more than expected during a manoeuvre, ISRO said in a statement on Wednesday.

This is the second time that the docking experiment has been postponed.
It was originally scheduled for January 7.

In a post on X, ISRO said, “While making a maneuver to reach 225 m between satellites, the drift was found to be more than expected post non-visibility period.”

“The planned docking for tomorrow is postponed. Satellites are safe,” it added.

Earlier, on Monday, the ISRO had postponed the docking of its SpaDex mission program, initially scheduled for January 7, 2025. The new date for the docking has been set for January 9, 2025. ISRO has not provided any specific reason for the schedule change.

On December 30, ISRO achieved a historic feat by launching PSLV-C60 with SpaDeX and innovative payloads.

The SpaDeX mission is a cost-effective technology demonstrator mission for the demonstration of in-space docking using two small spacecraft launched by PSLV. The primary objective of the SpaDeX mission is to develop and demonstrate the technology needed for the rendezvous, docking, and undocking of two small spacecraft (SDX01, which is the Chaser, and SDX02, the Target, nominally) in a low-Earth circular orbit.

Union Minister of State (Independent Charge) of the Ministry of Earth Sciences, Jitendra Singh, last week said that the SpaDeX mission was named “Bharatiya Docking Technology” because it is purely an indigenous mission, and India is carrying out the first such experiment related to docking technology.

The Union MoS further stated that SpaDeX’s mission very much aligns with Prime Minister Narendra Modi’s vision of “Aatmanirbhar Bharat.”

Blue Origin New Glenn Set for Launch on January 10 from Cape Canaveral

The highly anticipated debut launch of Blue Origin’s New Glenn rocket has been scheduled for January 10, 2025. The heavy-lift rocket, designed for both commercial and government missions, will take off from Florida’s Cape Canaveral Space Force Station. A launch window of three hours, beginning at 1 a.m. EST, has been announced. The rocket’s inaugural flight marks a significant milestone for Blue Origin as the company aims to validate its capabilities and establish itself as a major player in the space industry.

New Glenn’s Mission and Capabilities

According to Blue Origin, as reported by space.com, the New Glenn rocket is a reusable, 320-foot-tall launch vehicle capable of carrying 50 tons (45 metric tons) to low Earth orbit (LEO). The NG-1 mission will test the company’s Blue Ring spacecraft platform, which is designed to support a variety of orbital payloads. This demonstration will include assessments of communication systems, in-space telemetry, and ground-based tracking capabilities. The payload will remain aboard the rocket’s second stage for a six-hour mission, as stated by Blue Origin.

Booster Recovery and Future Goals

The mission will also attempt a recovery of the rocket’s first stage booster, which will land on a ship stationed in the Atlantic Ocean, as per reports from space.com. The company’s senior vice president, Jarrett Jones, emphasised the importance of the flight, stating that rigorous preparations had been undertaken but that true insights could only be gained through actual launch experiences.

NG-1 is a critical step toward securing certification for U.S. national security missions. A successful outcome would bring Blue Origin closer to fulfilling these high-stakes contracts, further solidifying its position in the competitive aerospace sector.

This launch will serve as a proving ground for the New Glenn system, with valuable data expected to inform future missions and technology advancements.

Spiders Detect Smells Through Leg Hairs, Claims New Study

Spiders Detect Smells Through Leg Hairs, Claims New Study

New research has revealed that spiders use specialised hairs on their legs to detect airborne scents, offering fresh insights into the sensory abilities of these arachnids. This discovery has resolved a long-standing question about how spiders, which lack antennae like insects, can identify odours such as pheromones. Male spiders were observed using olfactory hairs, known as wall-pore sensilla, to sense sex pheromones emitted by females. This mechanism underscores their ability to locate potential mates through chemical signals.

Olfactory Sensilla Identified

According to a study, published in the Proceedings of the National Academy of Sciences, the wall-pore sensilla were found on the upper legs of adult male wasp spiders (Argiope bruennichi). These microscopic structures are believed to be critical for detecting pheromones. High-resolution scanning electron microscopy revealed thousands of these sensilla, which were absent in females and juvenile males. This specific distribution supports their role in mate detection. Researchers emphasised to phys.org that these findings have mapped and identified the elusive sensilla, previously thought to be absent in spiders.

Response to Pheromones

Experiments demonstrated the sensitivity of these sensilla to pheromone compounds. Tiny amounts of the substance, such as 20 nanograms, elicited significant neuronal responses. The experiments involved exposing the sensilla to pheromone puffs, and responses were observed consistently across various leg pairs. The researchers concluded that spiders’ olfactory systems rival the sensitivity seen in insects, highlighting their advanced chemical detection capabilities.

Broader Implications

The study explored 19 other spider species and confirmed the presence of wall-pore sensilla in most male spiders, suggesting that this trait evolved multiple times. However, it was noted that some primitive species lack these structures. Future research is expected to investigate how female spiders detect smells, the types of chemicals relevant to their behaviours, and the evolutionary aspects of olfaction in spiders.

This breakthrough provides a foundation for understanding the sophisticated sensory mechanisms that govern spider behaviour.
