Is internet available in space?
The interplanetary Internet is a conceived computer network in space, consisting of a set of network nodes that can communicate with each other. These nodes are the planet's orbiters and landers, and the Earth ground stations.
Moreover, although the satellite's downlink is as broad as 300 mbps, the uplink is limited to 25 mbps. In terms of speed, the connection available to the ISS is comparable to that of ancient modems. On top of that, the station leaves the satellite coverage zone at intervals.
Yes, they can and do watch TV shows on the ISS. From an interview with Scott Kelly aboard the ISS: ... The agency said it's "somewhat slower because there are additional security measures in place to ensure the safety and integrity of the internet data that is viewable aboard ISS."
It has no phone number in the traditional sense, and astronauts have to leave their smartphones at home. For private calls, the space station has an internet-connected phone system that works through a computer, which astronauts can use to call any number on Earth. Phones on the ground cannot call them back, however.
“While the Moon doesn't have the level of interference found in a neighborhood full of houses and trees, it also does not have the advantage of an existing infrastructure of power, back feeds, and even a lunar internet, all of which need to be supplied,” said Oleson.
Several space agencies, including NASA, advise on playing games during their spare time. For this, here are several options available for the astronauts. Astronauts play various kinds of games, that entertains them and keeps them in shape.
Norway, the United Arab Emirates (UAE), and Qatar boast some of the fastest average mobile internet connections in the world, with each of these countries registering average median speeds in excess of 120 Mbps as of September 2022.
This post has been in heavy circulation on social media, making people feel bad about their relatively slow internet speed and hoping for a day that they too would be availing the internet at such astronomical speed. So, WHAT IS THE TRUTH? The Internet speed at NASA is not 91 gigabits per second.
The internet speed of NASA is exceptionally high thanks to the kinds of data they deal with. Their networks are capable of 91 gigabits per second, as they found out from an experiment they did in 2013.
No, there isn't sound in space.
This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.
Can we hear songs in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
The Outer Space Treaty
The treaty is the foundation of international space law for signatory nations (108 in 2019). The treaty presents principles for space exploration and operation: Space activities are for the benefit of all nations, and any country is free to explore orbit and beyond.
Yes, you can take pictures of objects in space through a telescope, but the approach and equipment configurations will vary depending on the subject matter.
But what of the average temperature of space away from the Earth? Believe it or not, astronomers actually know this value quite well: an extreme -270.42 degrees (2.73 degrees above absolute zero).
If the cell phone in the ISS uses the normal data rate for a small text message, it would be too fast for the distance. The antenna of a cell tower just below the ISS would be optimized for phone on the surface of Earth but not vertically above the tower.
At its very centre, the Moon has a solid iron core with a temperature of between 1,327°C and 1427°C. This is hot enough to create a surrounding molten liquid iron outer core, but not hot enough to warm the surface.
The gravitational pull of the moon moderates Earth's wobble, keeping the climate stable. That's a boon for life. Without it, we could have enormous climate mood swings over billions of years, with different areas getting extraordinarily hot and then plunging into long ice ages.
We cannot talk on the moon since there is no air present, Astronaut communicate with non-mechanical waves.
However, as astronaut Chris Hadfield notes, in microgravity, "your eyes make tears but they stick as a liquid ball." In other words, astronauts technically can't cry. Sure, you can get a watery substance to come out of your eyes, but it doesn't fall like it ordinarily does on Earth.
Recent research suggests it would not. For one thing, zero gravity can induce nausea—a less-than-promising sign for would-be lovers. Astronauts also perspire a lot in flight, meaning sex without gravity would likely be hot, wet, and surrounded by small droplets of sweat.
Do drugs work in space?
Astronauts on long space missions may not be able to take paracetamol to treat a headache or antibiotics to fight infection, a study has found. Scientists at the Johnson Space Center have shown that the effectiveness of drugs declines more rapidly in space.
One terabyte (TB) contains 1,000 gigabytes (GB). Most home connections are based on megabits per second (Mbps). A 1 GBPS internet connection is 10 times faster than Mbps connectivity and equal to at least 1,000 Mbps. What can you do with 319 Tbps?

On bases where Boingo service is available, troops can get basic Internet with a data transfer speed of 128 kilobits per second, as well as TV services with local channels, for free, the Navy Times reports. They also have the option to pay to upgrade to faster speeds and more channels.
According to the internet speed measuring site Speedtest on Tuesday, Korea's average broadband download speed was 171.12 megabits per second (Mbps) as of November, ranking 34th in the world. Korea's ranking dropped from No. 2 in 2019 to No. 4 in 2020 and No.
Even if you're enjoying gloriously fast broadband at home wherever you live in the world, you're still going to be a long, long way behind the new record for data transmission: an incredible 1.02 petabits per second. That's a million gigabits shifted down a line every single second.
Startup Aquarian Space has plans to bring WiFi to the moon in under two years. The company just received $650,000 in seed funding to deliver high-speed internet to the moon, and maybe even Mars.
But for NASA, it's downright slow. While the rest of us send data across the public internet, the space agency uses a shadow network called ESnet, short for Energy Science Network, a set of private pipes that has demonstrated cross-country data transfers of 91 gigabits per second--the fastest of its type ever reported.
Once transmitted to the lunar satellite, they were able to download data at a rate of 622 mbps, which is over 4,000 times faster than radio transmission speeds currently used to send information between Earth and the Moon, according to Wired.
What does space smell like?
We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.
The Sun does indeed generate sound, in the form of pressure waves. These are produced by huge pockets of hot gas that rise from deep within the Sun, travelling at hundreds of thousands of miles per hour to eventually break through the solar surface.
Space emits many wavelengths of light - including a lot of blue and red light that our human eyes can see - but also ultraviolet light, gamma rays, and X-rays, which remain invisible to us.
Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn't absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies. This artist's illustration shows NASA's New Horizons spacecraft in the outer solar system.
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.
Low-frequency background noise
Humans are unable to hear Earth's hum because it ranges between 2.9 and 4.5 Mhz. In general, humans can hear anything from 20 Hz to 20 kHz. So, this means that Earth's hum is about 10,000 times lower than what we are capable of hearing.
This gives rise to the question: what criminal law, if any, applies in outer space? The short answer is that, for a US astronaut aboard the International Space Station with a US alleged victim, US criminal jurisdiction applies.
The 1967 Outer Space Treaty bans the stationing of weapons of mass destruction (WMD) in outer space, prohibits military activities on celestial bodies, and details legally binding rules governing the peaceful exploration and use of space.
"You can't burp in space because the air, food and liquids in your stomach are all floating together like chunky bubbles," Hadfield replied on Twitter. "If you burp, you throw up into your mouth. So guess where the trapped air goes?" Air can, of course, travel from your stomach and out through your mouth in space.
NASA's Currently-Operating Space Internet Networks
The space component of the SN is called the Tracking and Data Relay Satellite system (TDRS). It is made up of 10 communication relay satellites in geosynchronous orbit and two ground stations.
How do astronauts have internet in space?
Internet connectivity in space is structured around a network of tracking and data relay satellites—the same fleet of communications satellites that NASA engineers on the ground use to communicate with astronauts on the International Space Station.
For the first time in history they're managed to prove that astronauts could enjoy the same connectivity as earthlings. Already, they've successfully transferred data at a rate of 19.44 megabytes per second, and downloaded it at a rate of 622Mbps.
Images taken by the Lunar Reconnaissance Orbiter (LRO) have shown that the American flags left on the Moon by Apollo astronauts are still standing– except for the Apollo 11 mission, which Buzz Aldrin reported as being knocked over by engine exhaust as Apollo 11 lifted off.
An amateur radio system is also on the International Space Station and is occasionally used by the astronauts. It broadcasts on 145.800 MHz. When the astronauts are not transmitting, a packet module serves as a relay for the computer messages of amateur operators on the ground.
Firstly, let's get the obvious out of the way: no, a smartphone can't make or receive calls in space, as it's reliant on ground-based antennas.
Yes it does! On average, a total of between 200-400 tracked objects enter Earth's atmosphere every year. That's about one every day! Thankfully human populations are rarely affected by things falling from the sky (from outer space).
In November, using this network, NASA's High End Computer Networking team achieved its 91 gigabit transfer between Denver and NASA Goddard Space Flight Center in Greenbelt, Maryland. It was the fastest end-to-end data transfer ever conducted under "real world" conditions.
NASA used a network called 'ESnet' for this test, which touts itself as a "high-performance, unclassified network built to support scientific research." ESnet is funded by the U.S. Department of Energy and allows organizations to transfer data to one another much faster than traditional internet services.
