When thinking of the power of the Ingenuity drone on Mars, which has done more than a dozen flights on the Red Planet to scout ahead of the Perseverance rover, imagine what it would be like to fly a similar machine over the moon.

But without a substantial atmosphere to speak of — the moon is essentially “airless” — such a hovering drone needs a completely different way to stay above ground than on Mars. The early-stage design, being developed at the Massachusetts Institute of Technology, proposes using the moon’s static charge to keep the vehicle flying.

The moon’s electrical properties are well-known to science, as it produces such qualities as hovering dust — especially at the line of daylight and darkness. Small rovers on the moon haven’t been used yet at all, although we have seen a few on the Japanese Hayabusa2 mission to asteroid Ryugu.

If you thought the Hubble Space Telescope was about to be surpassed by the new James Webb Space Telescope (Webb), think again.

Now on its way to its observing position a million miles from Earth, Webb has a 6.6 meter mirror–compared to the 2.4-meter mirror inside Hubble–so six times more collecting power.

Should we compare Webb with Hubble? No–Webb is an infrared telescope while Hubble deals mainly in optical (visible) light.

Planet-spotting is all about perspective.

From where we stand in our orbit of the Sun the closest planet to us, Venus, will come to what astronomers call inferior conjunction on Sunday, January 9.

After over six months of shining brightly in the west in the post-sunset sky in its apparition as the “Evening Star,” on that day Venus will finally disappear from sight.… See more.

H-Tec Systems receives research funding to advance research project PEP.IN with PEM electrolysers expertise as part of the H2Giga hydrogen project.

Augsburg-based hydrogen technology company H-Tec Systems is now officially part of the H2Giga hydrogen project for research & development into the series production of PEM electrolysis stacks and electrolysers. The German Federal Ministry of Education and Research (BMBF) is supporting H2Giga with a total funding volume of up to 500 million euros. The aim is to identify and test novel processes for the competitive mass production of electrolysers in Germany to make green hydrogen affordable and competitive.

As an expert and visionary in green hydrogen technology, H-Tec Systems is receiving research funding for the H2Giga project “PEP.IN” to further advance series production. By spring 2025, H-Tec Systems will identify new production processes for PEM electrolysis stacks and electrolysers in the gigawatt range and develop corresponding test facilities to quickly set up and commence series production.

Bluetti says its first-generation sodium-ion battery excels in thermal stability, fast-charging capacity, low-temperature performance, and integration efficiency, despite slightly lower energy density than its lithium-ion counterparts. The solar generator and battery’s chemical components also feature more abundant materials than traditional lithium-ion batteries, lowering prices and alleviating concerns about resources scarcity.

The NA300 solar generator delivers a 3,000Wh capacity, considerably less than the 5,100Wh of the company’s EP500 Pro model. But the generator capacity shouldn’t be a big issue for consumers, as it supports up to two B480 battery modules (4,800Wh each), which brings the total capacity to 12,600Wh. The unit, recharged by solar panels, can serve a family’s electricity needs for several days or even a week during grid failures or natural disasters.

It is said that the sodium-ion solar generator seamlessly inherits all the style and appearance settings of its predecessor – EP500 Pro – especially four 20-amp traditional wall plugs, as well as a 30-amp L14-30 output port, driven by the built-in 3,000W pure sine wave inverter.

Sure, a refrigerator can keep your veggies fresh… but LG’s tiiun can keep it fresher! Designed as a unique home appliance that lets you grow your own herbs and veggies the LG tiiun was announced in the run-up to CES 2022. The indoor gardening appliance is roughly the size of a dorm refrigerator, standing at approximately 3 feet tall, and features two shelves that can accommodate up to 6 all-in-one seed packages and various seed kits.

The term tiiun comes from the Korean word meaning ‘to sprout’ and is LG’s way of indicating that this appliance is an all-in-one self-sufficient garden. The appliance creates a perfect microclimate and all the right conditions for the plants to grow, even mimicking light cycles so you could potentially keep your tiiun anywhere in a room without worrying about access to proper sunlight. LG’s Flexible Weather Control System creates the ideal situations for organic growth while also keeping pests at bay. An internal watering system also delivers water to the plants (8 times a day) to keep them hydrated. All you really have to do is install the tiiun and sit back while your plants grow on their own!

Trojanized installers of the Telegram messaging application are being used to distribute the Windows-based Purple Fox backdoor on compromised systems.

That’s according to new research published by Minerva Labs, describing the attack as different from intrusions that typically take advantage of legitimate software for dropping malicious payloads.

“This threat actor was able to leave most parts of the attack under the radar by separating the attack into several small files, most of which had very low detection rates by [antivirus] engines, with the final stage leading to Purple Fox rootkit infection,” researcher Natalie Zargarov said.

Researchers have found a new bug in HomeKit ‘doorLock’ that affects Apple iOS devices.

Researchers demonstrate that electromagnetic signals emanating from IoT devices can be used as a side channel to detect various forms of malware.
