Spacetech startup Pixxel is set to launch its third hyperspectral satellite – Anand – onboard ISRO’s Polar Satellite Launch Vehicle (PSLV) from the Sriharikota spaceport on Saturday.

Anand is a hyperspectral microsatellite weighing less than 15 kg but having more than 150 wavelengths that will enable it to capture images of the earth in greater detail than today’s non-hyperspectral satellites that have not more than 10 wavelengths.

The imagery from the satellite can be used to detect pest infestation, map forest fires, identify soil stress and oil slicks amongst other things, a statement from Pixxel said on Monday.

“After more than 18 months of delay, many many retests, and more than two years of sweat and hard work by the team, we are finally launching this week,” Awais Ahmed, Founder and CEO of Pixxel said on Twitter.

Founded by Ahmed and Kshitij Khandelwal, Pixxel became the first Indian company ever to launch a commercial satellite – Shakuntala – in April using Elon Musk’s SpaceX’s Falcon-9 rocket.

Pixxel’s hyperspectral satellites are unique in their ability to provide hundreds of bands of information with global coverage at a very high frequency, making them ideal for disaster relief, agricultural monitoring, energy monitoring and urban planning applications, the company said.

The satellites are equipped to beam down up to 50 times more information with unprecedented detail, compared with other conventional satellites in orbit.

Pixxel has already inked partnerships with Rio Tinto and Data Farming which will use hyperspectral datasets to identify mineral resources and monitoring active and determining crop issues respectively.

The imagery from this will provide the team targeted inputs to improve the form factor and imaging capabilities of the next batch of commercial-grade satellites.

With this launch, Pixxel moves closer to achieving its vision of building a health monitor for the planet through a constellation of cutting-edge hyperspectral small satellites in space.

Pixxel is backed by Lightspeed, Radical Ventures, Relativity’s Jordan Noone, Seraphim Capital, Ryan Johnson and Accenture among others.

Dead NASA Satellite Relay 2 May Have Caused Mysterious 2024 Radio Burst

In June 2024, scientists detected a mysterious, powerful burst of radio waves originating from within our galaxy. At first, they thought it was coming from a pulsar or another undiscovered cosmic object. However, an analysis revealed the origin of the signal was too close to the Earth. Astronomers think it was caused by a long-dead NASA satellite Relay 2, was launched in 1964 but ceased operations in 1967 after its communication systems failed. Yet, nearly 60 years later, it mysteriously emitted a powerful radio signal, the researchers said in a new preprint study, which was posted June 13 to the server arXiv and has not yet been peer-reviewed.

Relay 2: A Silent Satellite Sends a Loud Signal

According to the study, the signal was detected using the Australian Square Kilometre Array Pathfinder (ASKAP) telescope array. These intense flashes typically originate from deep space and can carry more energy in milliseconds than the sun emits over several days.

But this signal, lasting just 30 nanoseconds, was traced back to the vicinity of Earth, too close for ASKAP to focus on clearly. After ruling out cosmic sources, the team traced the pulse to the orbit of Relay 2. Despite having no functioning systems, the satellite somehow emitted the brightest radio flash in the sky at that moment.

Researchers proposed two theories: a micrometeorite impact that created a radio-emitting plasma cloud, or an electrostatic discharge (ESD) caused by charge buildup on the satellite’s aging materials.

New Clues About Spacecraft Behavior and Space Debris

Though both mechanisms could produce similar signals, scientists lean toward electrostatic discharge as the likelier cause. According to space physicists, older spacecraft like Relay 2 may be especially prone to such energy releases due to outdated materials and limited shielding.

Karen Aplin told New Scientist that studying these accidental emissions could help monitor ESD events on today’s small satellites — many of which also lack advanced protection. In an increasingly crowded orbital environment, this detection method may offer a novel tool for evaluating space debris and satellite health.

James Webb Telescope Captures First Direct Image of Saturn-Mass Exoplanet

James Webb Telescope Captures First Direct Image of Saturn-Mass Exoplanet

The James Webb Space Telescope (JWST) has captured its first direct image of a newly discovered exoplanet. Astronomers announced that Webb imaged a Saturn-mass planet orbiting the nearby young star TWA 7. Dubbed TWA 7 b, the planet’s mass is only about 0.3 times that of Jupiter – roughly Saturn’s mass – making it the smallest planet ever seen via direct imaging. Most of the nearly 6,000 known exoplanets have been detected indirectly. To spot TWA 7 b, the JWST team used a coronagraph (like a solar eclipse) to block the star’s light and reveal the faint planet.

Detecting a Hidden World

According to the study published in the journal Nature, Webb’s team targeted TWA 7 because its dusty disk is viewed nearly face-on, revealing clear ring structures. They used Webb’s MIRI instrument with a coronagraph to mask the star’s glare. After processing the data, a faint infrared point source appeared roughly 1.5 arcseconds from TWA 7 (about 50 times the Earth–Sun distance).

This source lies in a gap of the star’s second dust ring. Its brightness and color match what theoretical models predict for a young, cold planet roughly Saturn’s mass. The object seems to be carving out the ring gap just as an orbiting planet would. Astronomers ruled out other explanations (like a background star) to confirm the signal is best explained by a planet.

A Step Toward Smaller Worlds

TWA 7 b’s Saturn-like mass makes it about ten times less massive than any exoplanet previously captured in a direct image. Its discovery shows that Webb can now image worlds far smaller than the giant exoplanets seen before. Scientists say the telescope may eventually detect planets as light as 10% of Jupiter’s mass, pushing toward Earth-like size.

This breakthrough “paves the way” to imaging truly terrestrial planets in the future. Astronomers even predict that upcoming observatories could dramatically increase the number of Earth-size planets seen by direct imaging. Next-generation telescopes – on the ground and in space – are being planned with even more powerful coronagraphs to hunt for the first directly photographed Earth analogues.

James Webb Telescope Detects Methanol and Ethanol Near Young Stars, Hinting at Life’s Origins

In the recent research done by using the James Webb Telescope, in March 2024, scientists found that ethanol and other icy organic compounds near protostars IRAS 2A and IRAS 23385. The findings were published in the JOYS+ program. It can offer insights into the cosmic chemistry that can help in knowing the formation of the planet and the potential for life on it. This also suggests how the building blocks in life can travel in space. The scientists observed alcohol in the orbit of a young star, adding to the understanding of life on Earth.

Methanol and Its Isotopes Detected Around Star HD 100453

As per the recent study conducted by NASA’s JWST, Methanol and its isotopes have been found in gases around the star called HD 100453. It is about 330 light years away from our planet. It has been observed for the first time that scientists have found isotopes of methanol in the shape of a disk. This was reported on June 5, 2025, in the Astrophysical Journal Letters.

Methanol: A Building Block of Life

Methanol acts as a building block for organic compounds like amino acids, which are essential for life. Researchers had found that methanol, but not the rare isotopes, is star-forming structures. These isotopes of methanol give a valuable insight into the ingredients needed for building life on Earth.

HD 100453: A Star Bigger Than the Sun

HD 100453 is larger than the Sun, with more than 1.6 times the mass of the Sun. This signals that methanol and other molecules in the disk exist as gas and farther from the home star, which could be the case when the solar system was quite young. The smaller stars consist of cooler disks, and the molecules are frozen and undetectable.

Link Between Methanol and Comet Chemistry

The researchers found that the ratio of methanol to other organic molecules is similar to that of the comets in the solar system. The findings signal that the ices near the protoplanetary disks clump to form comets filled with organic molecules, which are the result of collisions. This research gives the idea that comets may have played a major role in offering important organic material to the Earth billions of years ago.
