Space technology startups are being forced to limit their sky-high ambitions, as their venture-capital backers turn to safer bets due to the current economic turmoil, VC firm Space Capital said. Decades-high inflation, rapidly rising interest rates and the Ukraine war have roiled global financial markets, forcing investors to evaluate their investment strategies and focus on companies with viable products in the market.

Investments in space technology companies, which collect, process and analyze space-related data, have fallen 80 percent in the third quarter to about $1 billion (roughly Rs. 8,200 crore) from nearly $5 billion (roughly Rs. 41,200 core) in the year-earlier period, Space Capital said in a report.

“Venture Capitalists are refocusing on enterprise software-as-a-service companies and away from deep tech companies that provide solutions based on engineering innovation,” New York-based Space Capital said.

VC investment volume in space companies fell 44 percent, compared with a broader market decline of 31 percent, it added.

VC firms “are looking to reduce their exposure to capital intensive companies with low or long-term profitability models,” Space Capital’s managing partner, Chad Anderson, told Reuters.

“This is why space’s infrastructure layer will be the hardest hit during the economic downturn.”

The downbeat sentiment has also hit publicly traded “new space” companies such as Rocket Lab USA, Astra Space, Spire Global, and Satellogic, whose shares have fallen between 49 percent and 92 percent.

Many investors who explored aerospace last year have backed away, said William Kowalski, co-founder of Atomos Space, which makes spacecraft that help satellites maneuver in space.

“Fundraising has been challenging, but it has allowed more capital efficient companies to stand out,” he said.

Blue Origin’s New Glenn Rocket Moves Closer to First Orbital Launch

Blue Origin’s New Glenn rocket, the much-anticipated rival to SpaceX‘s Falcon Heavy, has taken a major step forward with a successful second-stage hot-fire test. This crucial test was conducted to validate key interactions between the rocket’s subsystems, its two BE-3U engines, and the ground control systems. The test, which lasted 15 seconds, represents a major advancement for New Glenn as it heads towards its first orbital launch in November 2024.

Validating the Second Stage Systems

The recent test focused on the New Glenn rocket’s second stage, ensuring its subsystems work cohesively under real-world conditions. The BE-3U engines, designed for high-energy missions, performed exceptionally well, demonstrating the thrust vector control system and the tank pressurization system to steer and fuel the rocket during its flight. The test also allowed Blue Origin’s launch operations team to rehearse critical launch procedures, ensuring the team was prepared for the November mission. This launch will take place at Cape Canaveral, Florida, from Launch Complex 36.

Looking Ahead: New Glenn’s First Mission

After several delays, Blue Origin has confirmed that New Glenn’s first mission (NG-1) will transport the Blue Ring orbital platform, designed by Blue Origin, into space. This mission marks a significant milestone for the company, which has thus far focused mainly on suborbital tourism with its New Shepard rocket.

A Rival to SpaceX

While Blue Origin has been slower to market, New Glenn is seen as a potential game changer in the commercial space industry. With a height of over 320 feet and its powerful BE-3U and BE-4 engines, New Glenn is built for ambitious missions, ranging from low Earth orbit to geosynchronous orbit.

Depression Could Be Linked With Brain’s Attention Guiding Network

Depression Could Be Linked With Brain’s Attention Guiding Network

New research is shedding light on the brain‘s role in depression, particularly through the discovery of an enlarged salience network in people suffering from the condition. This brain network, located primarily in the frontal cortex and striatum, is responsible for processing rewards and focusing attention on significant stimuli. The findings open promising avenues for early detection and personalised treatments for depression. The study claims that the brain network responsible for guiding attention was twice as large in those individuals who later developed symptoms of depression.

What is the Salience Network?

The salience network helps the brain determine which stimuli are most important and worthy of attention. It processes rewards and manages our focus on both external and internal factors. In people with depression, researchers have discovered that this network is significantly larger, potentially explaining the cognitive and attentional issues often associated with the disorder.

The Significance of This Enlargement

Studies have shown that the salience network in individuals with depression can be almost twice the size of that in healthy controls. Interestingly, this expansion does not fluctuate with changes in mood, suggesting that it is a stable trait rather than a symptom-based occurrence. This has led researchers to believe that an enlarged salience network could serve as an indicator of depression risk, even before the condition develops.

Implications for Early Detection and Treatment

This discovery could lead to innovative ways to identify individuals at risk for depression. Since the salience network can be detected early, even in children who are yet to develop depressive symptoms, this could transform preventative care. Furthermore, interventions targeting this specific network, such as neuromodulation techniques or personalised therapies, could become a future treatment path.

A Step Towards Precision Medicine in Mental Health

The research is still in its early stages, but experts believe that understanding the mechanisms driving salience network expansion could pave the way for new pharmaceutical and therapeutic interventions. By focusing on how this network contributes to depression, scientists hope to tailor treatments more effectively, improving patient outcomes.

Did Pollen Allergies Lead to Woolly Mammoth Extinction?

Did Pollen Allergies Lead to Woolly Mammoth Extinction?

Woolly mammoths have long been thought to have disappeared due to a combination of factors, such as climate change and human activity. However, a recent study proposes an unexpected hypothesis: pollen allergies may have played a role in their extinction. The study suggests that at the end of the last Ice Age, a surge in vegetation led to excessive pollen production. This may have triggered allergic reactions in mammoths, impacting their sense of smell. Since mammoths relied heavily on smell for various vital functions, such as finding food, evading predators, and locating mates, pollen-related allergies could have severely disrupted these abilities.

Could Allergies Explain Extinction?

Researchers argue that this impairment during mating season may have made it difficult for mammoths to communicate and breed, contributing to a sharp population decline. However, further testing, including examining fossilized mammoth remains for immune proteins associated with allergic responses, is needed to confirm this theory.

Scepticism Around the Hypothesis

While the study presents a compelling narrative, not all experts are convinced. Evolutionary biologist Vincent Lynch, for example, points out that mammoth extinction is more likely to have been caused by a combination of environmental shifts and human hunting. Until more concrete evidence emerges, the pollen allergy theory remains an intriguing but debated topic in mammoth research.
