The Official iOS App For ChatGPT Is Out

The wait is finally over sort of, OpenAI has launched a free ChatGPT app for the US iOS users only. As Android users, the company behind the AI language model promises that you guys won’t be left behind “You’re next!”. If you are conversant with the web version of ChatGPT, the app version shares the same similarities. Since it’s a mobile app, it allows for voice input using OpenAI’s Whisper…

What We Learned from Flying a Helicopter on Mars

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.

Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.

So, what did we learn from this small but mighty helicopter?

We can fly rotorcraft in the thin atmosphere of other planets.

Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.

Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.

Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.

Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.

Creative solutions and “ingenuity” kept the helicopter flying longer than expected.

Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.

There is value in adding an aerial dimension to interplanetary surface missions.

Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.

After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.

Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.

Tech demos can pay off big time.

Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.

Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.

In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.

You can fall in love with robots on another planet.

Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

I love supportive parents Fentons. We're they good parents? Not always but they are trying. More so now that they knew how they'd failed Danny. They did a 180 on their research going from Ghost are evil to ghost are just people. Though some ghost wish they still just acted violently rather then stalking them to ask so *so* many questions.

Danny is happy, his parents are trying and while the GIW are still around as a nuisance he doesn't see then as actually a threat. Everyone in Amity had started treating him better both in and out of Phantom form. He is thriving.

Enter Constantine, there on league business. That business is decommissioning the GIW. The acts had been repealed and the group was supposed to cease activity. But they kept those things from Amity park and everyone there. How the league found out about it was just superman overhearing the agents brag about how they still worked in Amity.

Constantine had a fine time with the civilians there until he mentioned working for the league. Suddenly everyone turns on him. They don't harm him but they ice him out, over charge anything he buys, and hurl insults. He was also pretty sure his string of bad luck was caused by them too not just the obvious things.

So the hellblazer has no choice but to ask the local heros. Phantom tell him to leave, that he had it all covered. Red huntress is luckily more forth coming. If by forth coming you meant telling the truth while insulting a person and group so bad it makes him want to retire. Seriously he knew teens could be vicious but this is special levels of vitriol.

Once he finds out the situation, he can feel a migraine coming on. Not only did the league not answer a call for help repeatedly, but the local heros were two teens who think the league was for the anti-ecto acts. Plus neither of them were *good* at hiding their identities. Phantom was a palate swap and used a pun on his own civilian name. Red huntress Aka Valerie was *proud* of being red huntress and saw no real reason to hide it anymore.

The town is shocked when the league member in town starts taking down the GIW. Even more shocked when he told everyone the acts were repealed. They don't warm up to him though. Well things are better priced again at least.

As he finishes up and prepared to leave, he is stopped by the town mad scientist. They're smiling at him but he just knows this was about to be bad. Which is only proven when the lady pulls out a note pad and pen and he is being given the third degree on how magic works.

Constantine tries to leave he really does. But the man Jack has him body blocked via side hug he can't escape from. They wouldn't take his non-answers as answers and he felt his day get *worse* when they ask him to teach them.

The Fentons want magic only so they can figure it out. Magic doesn't exist so what ever power the hellblazer has has to be ecto based! And they need answers! It could help their son master his own powers and they could finally join him in fights on equal footing. A family that fights evil together stays together. Danny would be so proud of them!

Constantine doesn't want to deal with possible future magic rogues so he hits his s.o.s beacon in his pocket as he goes for a cigarette. He'd get shit for it later but he could handle a Bat lecture not what ever this was.

"When a severe water shortage hit the Indian city of Kozhikode in the state of Kerala, a group of engineers turned to science fiction to keep the taps running.

Like everyone else in the city, engineering student Swapnil Shrivastav received a ration of two buckets of water a day collected from India’s arsenal of small water towers.

It was a ‘watershed’ moment for Shrivastav, who according to the BBC had won a student competition four years earlier on the subject of tackling water scarcity, and armed with a hypothetical template from the original Star Wars films, Shrivastav and two partners set to work harvesting water from the humid air.

“One element of inspiration was from Star Wars where there’s an air-to-water device. I thought why don’t we give it a try? It was more of a curiosity project,” he told the BBC.

According to ‘Wookiepedia’ a ‘moisture vaporator’ is a device used on moisture farms to capture water from a dry planet’s atmosphere, like Tatooine, where protagonist Luke Skywalker grew up.

This fictional device functions according to Star Wars lore by coaxing moisture from the air by means of refrigerated condensers, which generate low-energy ionization fields. Captured water is then pumped or gravity-directed into a storage cistern that adjusts its pH levels. Vaporators are capable of collecting 1.5 liters of water per day.

Pictured: Moisture vaporators on the largely abandoned Star Wars film set of Mos Espa, in Tunisia

If science fiction authors could come up with the particulars of such a device, Shrivastav must have felt his had a good chance of succeeding. He and colleagues Govinda Balaji and Venkatesh Raja founded Uravu Labs, a Bangalore-based startup in 2019.

Their initial offering is a machine that converts air to water using a liquid desiccant. Absorbing moisture from the air, sunlight or renewable energy heats the desiccant to around 100°F which releases the captured moisture into a chamber where it’s condensed into drinking water.

The whole process takes 12 hours but can produce a staggering 2,000 liters, or about 500 gallons of drinking-quality water per day. [Note: that IS staggering! That's huge!!] Uravu has since had to adjust course due to the cost of manufacturing and running the machines—it’s just too high for civic use with current materials technology.

“We had to shift to commercial consumption applications as they were ready to pay us and it’s a sustainability driver for them,” Shrivastav explained. This pivot has so far been enough to keep the start-up afloat, and they produce water for 40 different hospitality clients.

Looking ahead, Shrivastav, Raja, and Balaji are planning to investigate whether the desiccant can be made more efficient; can it work at a lower temperature to reduce running costs, or is there another material altogether that might prove more cost-effective?

They’re also looking at running their device attached to data centers in a pilot project that would see them utilize the waste heat coming off the centers to heat the desiccant."

Launch Your Creativity with Space Crafts!

In honor of the completion of our Nancy Grace Roman Space Telescope’s spacecraft — the vehicle that will maneuver the observatory to its place in space and enable it to function once there — we’re bringing you a space craft you can complete at home! Join us for a journey across the cosmos, starting right in your own pantry.

Stardust Slime

Ingredients:

1 5 oz. bottle clear glue

½ tablespoon baking soda

Food coloring

1 tablespoon contact lens solution

1 tablespoon glitter

Directions:

Pour the glue into a bowl.

Mix in the baking soda.

Add food coloring (we recommend blue, purple, black, or a combination).

Add contact lens solution and use your hands to work it through the slime. It will initially be very sticky! You can add a little extra contact lens solution to make it firmer and less goopy.

Add glitter a teaspoon at a time, using as much or as little as you like!

Did you know that most of your household ingredients are made of stardust? And so are you! Nearly every naturally occurring element was forged by living or dying stars.

Take the baking soda in this slime recipe, for example. It’s made up of sodium, hydrogen, carbon, and oxygen. The hydrogen was made during the big bang, right at the start of the universe. But the other three elements were created by dying stars. So when you show your friends your space-y slime, you can tell them it’s literally made of stardust!

Still feeling crafty? Try your hand at more pantry projects or these 3D and paper spacecraft models. If you’re eager for a more advanced space craft, check out these embroidery creations for inspiration! Or if you’re ready for a break, take a virtual tour of an interactive version of the Roman Space Telescope here.

Does a USB drive get heavier as you store more files on it?

Nope. Paradoxically (and theoretically), the more you save on a flash drive, the lighter it gets.

USB drives use Flash memory, which means the the ones and zeros of the data are stored on transistors.

When you save data, a binary zero is set by charging the float gate of the transistor, and a binary one is set by removing the charge.

To charge it, we add electrons, and the mass of each electron is 0.00000000000000000000000000091 grams.

This means that an empty USB drive (which mostly holds zeros) weighs more than a full USB drive (which has ones and zeros). Add data, reduce the weight.
