Hydrogen Bomb works because of nuclear fusion. Our Sun also works because of nuclear fusion. Yet our Sun is stable and doesn't explode like a bomb.
Why? Something Ain't right!

In the 3rd episode of Free Return Trajectory, NASA and the other space agencies try to figure how to investigate the Gale Crater event further using the surviving hardware they have on the Red Planet.
Over the past 50 years, humans have visited just about every type of celestial body in the Solar system. And in many cases we've even landed on them. However each landing has to be handled differently based on the environment and the payload that's being delivered.
Join me in this episode of Celestial Sphere as we take a look at the principals and methods we use to land on these celestial bodies .

Humans going into space and orbiting the earth is something that happens routinely these days. Even though it's a really a small step when it comes to travelling among the stars, this small was just a dream 150 years ago. The knowledge of many people contributed to the designs of the machines that got us where we are so today. We are still far from travelling among the stars but still, getting to where we are now took a spark.
A spark of inspiration from a few individuals. This video is about one of them.

At some point in the future we will have some kind of permanent human presents on the moon. And when that happens we would have already located reliable sources of what little amount of water that's located on the moon.
In this first episode of the reimagined Sensing the Universe we take a deep dive into CHACE. An instrument that helped us locate water on the moon.

With a glass of water costing about $4400 on the International Space Station, it was just a matter of time before a way was found to to drink that water more than once. But it's not just about cost. On a long journey to Mars, it about the availability.
In this episode of Celestial Sphere we take a detailed look at the devices to turn Urine in to drinkable water.

There are many ways to separate a spacecraft from it's launch vehicle. In this video we look at a system called Motorized Lightband.
This video is from my other Operational fact. Short clips of how things work. Not just space related stuff but anything that can be explained with a good animation. No intro, no outro, just the facts of the matter. Most videos there are under two minutes. The new channel contains a lot of clips from this channel stripped down to just the point. This makes it a good channel for quick reference about stuff and that's the point.

A rocket can get a payload into space in just minutes. But preparing a rocket for liftoff will take weeks or months. There are many moving part of a rocket that needs to be brought together in a particular order within a narrow time frame. In this video we will start our journey after the payload has been assembled and on it's way to the launch pad. We will be following the countdown sequence of Ariane 5. This is the workhorse of ESA.
Important Note:
A lot of Information available for the Ariane 5 is in french. Since I'm not a fresh speaker or more precisely a french reader I had to depend on automated translations. So I may get a few things wrong about the sequence of events. Also keep in mind that as far actual times for events goes, they may differ from the most recent sequence used by ESA. So check with them first before you design your payload around the launch sequence shown here.
Additional note:
This is my first video that is 100% animation. This is why it took so long to create. Real imagery of a launch sequence is just not available so there was not choice. Also I had to create all of the 3d models in the opening except for the Ariane 5. Interestingly this video is not just the longest one to make, it also has the longest running time.
Hope you like it and leave a comment if you spot any error or just leave a comment if you like.

Radio science modules have become standard scientific instruments on many deep space missions. they provide a cost effective way to gather information such as mass, atmospheric temperature and pressure of a celestial object. This is the second haft and more detailed look of how radio science works.

Trying to live on another planet is a very risky goal even if it's just a little outpost with a small crew. From the the trip itself to sustaining the crew for a month or so in an environment that is not well understood., the risk of failure can be high if we don't have the proper data we need to model the environment sufficiently enough to minimize risk of failure.
NASA's Perseverance Rover will give us some of this vital data as we prepare to make planetfall on Mars in the 2030's

Mars has the closest environment that matches that of Earth. Because of this the possibility of life existing on Mars seems to be a reasonable assumption. In 1976 NASA made the first and so far the only attempt to answer that question. In this episode of Sensing the Universe we take a look at the technical side of what NASA did.

Before a spacecraft can be launched into space it must go through a battery of test. The most important ones are performed inside a space simulation chamber. These chambers replicate the conditions of space as much as possible. In this episode I discuses what these chambers are and how they work.

Since Voyager 1 detected organic molecules in Titan's Atmosphere scientist have a strong interest in finding out the process that creates them. But that requires analyzing the atmosphere in situ. With Titan 1.2 billion km from earth that seemed to be a tall order until Huygens made landfall.
In this video I discuss one of the main instruments responsible for gathering data on the organic particles in Titan's atmosphere. The Aerosol Collector Pyrolyzer.

When a spacecraft is too big to fit inside a rocket fairing we fold it. Unfolding a spacecraft in space is a tricky process that has to be done in a particular order and often within a certain time frame after launch. That’s because in the folded state a spacecraft is unable to generate power unless it’s nuclear powered. It’s also unable to communicate with earth efficiently if at all in the folded state. The fact that without power and communication a spacecraft is totally useless makes the unfolding process that much more critical.
But unfolding it it is not guaranteed if it its not done in the correct way.
In this video we talk about Hold Down Release Mechanism (HDRM) and how they are strong enough to secure a spacecraft during launch but are able to release it on demand later in space.

Up until 200 ago we thought that the sun only generated light and heat. We also thought it had no other effect on the solar system aside from gravitational effect.
We now know that the sun streams out sub atomic particles.
Collectively known as the solar wind these particles can dramatically change a planet over time.In this episode In this episode we take a detailed look at The Solar Orbiter spacecraft that will be studying the solar wind. I will launch in February of 2020. Specifically we will be looking at the Solar Wind Plasma Analyser.
