NASA’s cool new laser system is being used to send astronauts videos of their pets

To send and receive messages to and from the International Space Station (ISS), NASA has built the first end-to-end wired system that works both ways. With its 1.2 gigabits per second speed, which is faster than your home internet, it sent pictures and videos of cats, dogs, and even the occasional parrot to the astronauts who are currently on the station.

Space communication is slow for more than just the reason that light moves so slowly. It took over a year to send a few days’ worth of observations from missions like New Horizon, which was the first mission to Pluto. It will be possible for future missions to carry more instruments with better resolution, but that won’t help much if we can’t get the data back to Earth.

Lasers can make the speed at which data is sent much faster. A mission called Psyche is going to look into the metal-rich asteroid with the same name. It has an infrared laser system on board called Deep Space Optical Communications (DSOC). Last year, it was shown off from 40 million kilometers away, which is 16 million kilometers (10 million miles).

It took DSOC an extra month and 3 million kilometers to get to the important stuff. Of course, Psyche sent a video of Taters, a cat, chasing a laser dot.

But this only went one way. The video was put on Psyche before it opened. At the moment, there is no quick way to send that much data to a spacecraft so far away.

But the ISS is not like that. The mission operations center in Las Cruces, New Mexico, sent data to ground stations from Texas to Hawaii. The first set of data included pictures and videos of the staff’s pets. At these points, it was changed into infrared laser signals and sent into space.

As you might expect, the signals weren’t sent straight to the ISS. Instead, they were sent to satellites in geosynchronous orbits 22,000 miles above Earth. From there, everything was sent to a receiver that was temporarily attached to the outside of the ISS. All of those valuable bits were sent back to Earth, showing that the system works both ways.

We are used to information traveling at the speed of light, so this may not seem very impressive, but it was very hard to do technically. Radio waves can only carry so much data at a time. Infrared lasers can carry more data, but delays can cause important data to be lost over these distances, let alone the ones NASA wants to use these systems for in the future. A new “store-and-forward” process was put to the test during the demonstration. This process checks the quality of data and either sends it right away or stores it for later use.

A High-Rate Delay Tolerant Networking (HDTN) system was created so that this could happen four times faster than it could before. Astronauts on the Artemis Mission will need improvements like these so they can connect to the Internet instead of sending their videos in grainy black-and-white like Apollo astronauts did.

NASA’s Kevin Coggins said in a statement, “Not only did they show how these technologies can be an important part of NASA’s future science and exploration missions, but it was also fun for the teams to “imagine” their pets helping with this innovative demonstration.”

We commend NASA for the technology and the things they sent, but we can’t help but feel like they missed a chance. These pets belonged to astronauts Randy Bresnik, Christina Koch, and Kjell Lindgren, as well as to people who work for NASA but have never been to space. We especially like Astrid the Beagle because the breed is linked to scientific progress.

Still, none of these astronauts are on board right now. The current crew must miss their own pets and would have liked a video from whoever is taking care of them. Next, astronauts will face-time with their excited dogs (the cats won’t mind).

Ten million people play The First Descendant in its first week

The free-to-play shooter The First Descendant has gotten a lot of attention in its first week. The game’s publisher, Nexon, says that 10 million people have already tried it out.

Insider Gaming pointed out that since there is no cost up front, it’s still too early to tell how many of those players will stick around, but it’s still a big number for a new IP. On Steam alone, it peaked at 264,860 concurrents right after launch and has still managed to break 200,000 in the last 24 hours, so it looks like a lot of people are still really into the game.

It was a “mindless and repetitive grind,” and we gave The First Descendant a 3/10 in our review. Of course, that’s just one opinion; other experts have had different ones. Most people, though, say that the game’s annoying free-to-play model is the worst thing about it.

Are you one of the millions of people who played The First Descendant last week? Are you going to come back for more? Leave a comment below and let us know.

The trailer for Gladiator II looks great, but is any of it true? What Did The Experts Say?

The trailer for Gladiator II by Ridley Scott is now out, and it looks like it will be the best movie ever. If you liked the first movie, you’ll probably love the new one, which has a lot of big names in it and shows epic duels, scary Colosseum battles, and hints of political intrigue. But, as with all Hollywood historical epics, you might wonder how much of what is shown is based on real events and how much is just made up for fun.

When we had questions, we asked the Bad Ancient team what they thought about the fun, the fantasy, and the facts.

What’s the movie about?
The new Gladiator movie picks up 25 years after the first one. Paul Mescal plays Lucius Verus II, the boy from the original story and Lucilla’s son. The trailer starts with him talking about the deadly duel between Emperor Commodus (Joaquin Phoenix) and Maximus Decimus Meridius, a gladiator and fallen general.

It looks like Lucius is living in exile in Numidia, which is in northwest Africa. A few years after this incident, the Roman army captures him and forces him to compete as a gladiator. Lucius wants to overthrow the Roman government and end all forms of slavery, of course.

Later, Lucius fights the made-up General Marcus Acacius (Pedro Pascal), who also seems to have doubts about the Roman Empire’s needless killing. In the trailer, we learn more about characters like Macrinus (Denzel Washington), a power broker who likes gladiators, and Geta and Caracalla, two brother emperors who look cruel and spoiled and are played by Joseph Quinn and Fred Hechinger, respectively.

There are hints of exciting scenes in the trailer, like a gladiator riding a rhino and a fake naval battle in a flooded Colosseum with boats and sharks that eat people. There are also hints of politics and mystery.

A lot of it. It’s fun, but is it really true?

First, what did you think of the trailer?
Dr. Jo Ball (JB), an archaeologist who studies Roman war and conflict: I was really looking forward to seeing the trailer for the new Gladiator II movie, and it did not let me down. It looked like it would be a great visual feast, with hopefully some good history thrown in. I’m especially interested in seeing how Pedro Pascal’s character, Marcus Acacius, fits into the story. From the trailer, he seems to be coming to protest the endless conquests of Rome and the lives it took, and he seems to be getting in trouble for his views. I think this could be an interesting way to connect this to the main gladiator theme.

Alex Sills (AS), a graduate student at the University of Leicester: The sheer spectacle of it looks like it will be even better than the first movie. I can’t wait to see what 24 years of CGI progress can do for a Roman arena. Also, I’m interested to see how the movie handles the fact that the Republic hasn’t been brought back. Maximus gave up his life for that reason in the first movie. Will Lucius finish the job? We know that emperors ruled for hundreds of years, so it’s not likely. However, it will be interesting to see if the political aspect is kept up or dropped in favor of a story about revenge between two people.

This is Dr. Owen Rees (OR), founder and chief editor of Bad Ancient: I love the first Gladiator movie so much that my first thought was, “Why?!?” Why is there a second part? But when I saw the cityscape of Rome on the screen, that reaction went away, and I became interested in what I was seeing. The glory of Rome, the desire for a quiet life away from the center of power, and the idea of “the Republic” are all themes that were introduced in the first movie. I can’t wait to see how they connect these to the second one.

Did anything stand out right away as being right or wrong or not making sense?
JB: Paul Mescal’s Lucius seems to have become a gladiator after being captured during a violent conquest of Numidia in northwest Africa. However, this area had been a part of the Roman world for hundreds of years by the time the movie takes place, and it’s hard to imagine scenes like the ones in the trailer happening during the time of the movie’s setting, when Severus reorganized the region’s government.

Some parts of the dress don’t seem right, like the wristbands that everyone with a sword seems to have to wear! The accents are an interesting mix, but I actually quite like this, as it is a useful reminder that the “Romans” were not a homogenous population but came from an empire that stretched from Britain across Europe, the Near East, and northern Africa—why people would be expected to have the same accents is beyond me (and even if they did, a modern American accent is no less accurate a representation than a classic British one!).

AS: No one is without a top! They didn’t wear anything to protect their torsos because that would have been too easy of a fight. Also, Pedro and Paul should have shields with them, since that’s what gladiators did instead of chest armor. It’s cool that the shield could be used offensively, almost like a second weapon. Having both arms in the fight makes it more interesting. Of course, movie stars shouldn’t have to wear helmets that cover their faces, but these guys should be able to show a lot of chest. I’m sure a lot of people in the theater would also not mind…

Is there something wrong with how the two emperors are portrayed?
Basically, Caracalla and Geta are portrayed in a rather odd way. They seem to fit the stereotypes of Nero and Caligula more than they do the real Severans. Also, they stand out because they are so pale. Both brothers were born in Syria and Libya.

In Roman times, there were a lot of people of color. It’s not fair to make emperors with darker skin look lighter. I’m happy to see Denzel Washington in the cast, though, because his character sounds really interesting.

OR: They look like a cliché of many “bad emperors” rolled into one. It’s interesting that they chose to cast actors who are so pale these days. But we’ll see how their characters are developed when the movie comes out. You can’t judge it based on a few seconds in an ad!

When it was full of water, did the Colosseum ever host battles on the water?
JB: Yes, naumachiae were popular and spectacular shows put on to entertain the people of Rome on special occasions. They were very expensive and hard to set up. Early Roman emperors put on Naumachiae, but until Nero’s time, they didn’t happen in amphitheaters. Instead, they happened on lakes or in specially built basins. The Colosseum was a special place for naumachiae, and one was even held at its opening in 80 AD, during the reign of Titus the Great. But we don’t know how they filled the arena with water for the battle; it was probably done to the lowest level possible so the ships could float!

But Paul Mescal’s character wouldn’t have fought in Naumachiae. The Romans didn’t use trained (read: expensive) gladiators. Instead, they used prisoners of war and criminals who had been sentenced to death. This suggests that very few, if any, were expected to survive. It’s also important to note that the naumachia of Claudius on the Fucine Lake was the only time that people were heard saying, “We who are about to die salute you.” The gladiators didn’t need to say this.

What if gladiators had fought rhinos or sharks instead?
JB: Roman audiences liked new things in their beast shows, and there weren’t many animals that they wouldn’t put in the arena. In fact, it was a big business to get animals for these kinds of shows, and the more exotic the animals, the better. The animals didn’t even have to be very dangerous; as long as they were different, they were included. Giraffes were shown with “classic” wild animals like lions and bears.

: Gladiators always fought other gladiators. On the other hand, there were people in the arena who fought animals or hunted them. These people were called devas and bestiarii.

Rhinos were shown off in Rome—that much we know. I think Pompey Magnus was the first person to bring one in. One was brought in so that the emperor Commodus (Joaquin Phoenix in the first movie) could kill it himself in the Colosseum. He did this by shooting it with arrows from a platform, so he was never in any danger.

When it comes to sharks, we’re getting into fantasy land. The Romans got very good at catching and moving all kinds of wild animals, especially from Africa. But they couldn’t catch sharks, bring them to Rome, or put them somewhere safe before the Games. But if they had been able to, they would have thought it would have been awesome, so maybe this is dead guys’ movie wish fulfillment.

OR: There were animals in the arena, but the gladiators who fought were not the same ones. We use the word “gladiator” to describe too few of the people the Romans had in the arena.
