Happy birthday to Yuri Gagarin and happy birthday to Valentina Tereshkova, the first people in space! Yuri Gagarin was born on March 9, 1934 and was the first man in space, while Valentina Tereshkova was born on March 6, 1937 and was the first woman in space!

I know it's been a while, but I'm posting this bearing in mind that today is also Donald's birthday (in addition to June 9). I certainly love that both Donald and Della in the cartoons and comics love space travel and that they are both astronauts and I would love to see more stuff like that about the two of them as well as the Duck family going into space. Yes, Gagarin also means duck.

Orthodox Christian Faith among Soviet Cosmonauts

Remarkably, even though the first Russian cosmonauts were members of the Communist Party, their journeys into space were closely connected with their spiritual life. In various ways, before or after their epic space odysseys, they experienced moments of profound connection with the divine. Their experiences were punctuated by miraculous events, occurring through their faith and prayers and with the mysterious help of the many sacred relics that accompanied them.  In this article, we delve into these cosmic encounters, exploring the intersection of faith, science, and the mysteries of the universe.

"Why is it that cosmonauts always have girls (daughters)?"

"Maybe because girls are cool."

Most of the pioneering cosmonauts were parents of girls, so here are the proud dads (and mom) and their girls! Happy International Women's Day! 👩🏻‍🚀💐💫

lesbian yuri pfps (i will use one for my twitter account at some point) i made on canva because he is technically a lesbian to me, just like every man called "yuri".

nothing i do gets really viewed by people but i say this just to be sure : if you decide to use them (these ones specifically) i would appreciate if you tagged me.

How do astronauts determine mass in space?

Post #20 in Physics and Astronomy, 13/03/2024

It's been a while, welcome back:

Anyone with a small volume of physics knowledge will know that there’s a distinct difference between mass and weight. Mass is independent of environment, however an object’s weight will vary depending on the environment’s gravitational environment. For example, an object with a given weight on Earth will weigh less on the International Space Station.

Weighing yourself on Earth

This is a pretty simple feat. You simply stand on a scale, and the scale will record your weight. A spring obeying Hooke’s Law, with a known spring constant, is used, and the displacement of the spring when an object is placed on it is used to provide an estimate of the gravitational force applied by the object. Mechanisms within the scale will help convert the spring motion into a reading on the dial. 

However, in an area of microgravity or zero gravity, this will no longer work, since objects won’t exert that same gravitational force on a scale in space.

Why astronauts need to weigh themselves

In space, astronauts lose muscle mass and bone density very rapidly. While on Earth, gravity is constantly acting on us, so even if you may not realise it, your lower body’s muscles are constantly working, one way or another.

If you’re not on Earth anymore, however, this is no longer the case. The force due to gravity no longer acts on your body; people can go by without having to stand on their legs or physically walk around. This is why you may know that astronauts have to spend a lot of time exercising while in space; it’ll help reduce the rate of muscle mass loss and weakening bone density.

How do astronauts weigh themselves?

Springs, similar to before, are the key to solving this. While they’ve been implemented in numerous ways, the main two are shown through NASA’s Space Linear Acceleration Mass Measurement Device (SLAMMD) and the Russian Body Mass Measurement Device. 

According to Newton’s Second Law, force is equal to the product of mass and acceleration. If a spring can always produce the same force, a measurement of the object’s acceleration due to that spring can be taken, and this can be used to calculate mass.

SLAMMD involves an astronaut grabbing onto something while being pushed a meter. By measuring the astronaut’s acceleration during this mass, a very accurate measurement of the astronaut’s mass can be made. 

On the other hand, BMMD involves measuring oscillations. This device pushes an astronaut back and forth, and measuring how long the oscillation lasts gives a pretty good estimate of the astronaut’s mass.

Why this all of a sudden?

Not long ago, I had the pleasure of taking part in a space workshop led by the National Space Centre. Myself and a number of students taking Further Maths + Physics engaged in various experiments throughout the day, however, a particular one caught my eye.

It involve shaping a little astronaut using playdough, then timing twenty oscillations of varying masses on the end of a flexible metal “rod” of sorts. This experiment was inspired by the BMMD! In doing so, we determined the mass of our little “astronaut” by timing how long twenty oscillations took, then checked it up against the graph.

I was doubtful that this experiment would work, however the calculated uncertainty in the end was a mere 2%! Our determined mass was extremely close to the true mass of the astronaut, and that was what inspired me to write this today.

The workshop was delivered by Emily Perkins, a physics teacher once mistaken for Cloud 9’s Perkz! This experiment had been on my mind ever since and I just had to write something about it.

This is already the 348th correction of the ISS orbital altitude in the history of the station’s flight. This morning, October 19, 2023, the orbit of the International Space Station was adjusted to create the necessary ballistic conditions for the launch of the Progress MS-25 cargo ship. The press service of Roscosmos spoke about this. [caption id="attachment_71697" align="aligncenter" width="780"] MS-25 spacecraft[/caption] The engines of the Progress MS-24 cargo ship docked to the Zvezda service module of the Russian segment of the ISS, were turned on at 06:46 Moscow time and worked for 1029.9 seconds, producing an impulse of 1.5 m/s. After the maneuver, the average altitude of the ISS orbit increased by 2.8 km and amounted to 418.23 km above the Earth’s surface. ISS is being prepared for the launch of the Progress MS-25 spacecraft During the entire flight of the ISS, 348 corrections to the altitude of its orbit were carried out, 194 of them using the engines of the Progress spacecraft. The launch of the Progress MS-25 cargo ship from the Baikonur Cosmodrome using the Soyuz-2.1a launch vehicle is scheduled for December 1, 2023. Currently on board, the ISS is the crew of the 70th long-term expedition, which includes cosmonauts Oleg Kononenko, Nikolai Chub, and Konstantin Borisov, NASA astronauts Jasmine Moghbeli and Loral O'Hara, ESA astronaut Andreas Mogensen and JAXA astronaut Satoshi Furukawa.

Briefly returning to say that I'm deeply saddened to hear about the passing of Mirosław Hermaszewski (15/11/1941 – 12/12/2022). In June 1978, he spent 8 days aboard the Salyut 6 space station as part of the USSR's Interkosmos program, becoming Poland's first (and so far only) cosmonaut.

Thank you, sir, for your contribution to space science, and for proving once and for all that Poland CAN, in fact, into space.

Today is the 59th anniversary of the first ever spacewalk in the history of humanity !! The cosmonaut-painter Alexei Arkhipovitch Leonov (Алексе́й Архи́пович Лео́нов) realised it on this day, the 18th of March, in 1965 !!

🎨🚀🛰️👨🏼‍🚀🌌💙

Here he is with three of my other favorite cosmonauts : Yuri Gagarin, Boris Volynov and Sigmund Jähn !!

Alexei Leonov painted since childhood, and very well, so he obviously portrayed his experience as the first man going outside in the cosmos. Here are some paintings of him that I particulary love. The first one is the one he realised while on board of the Voskhod 2 flight mission, which is the first art made in space, representing the sunrise over the Earth.

I really adore how his art makes space look so silent and almost terrifying because of its endless immensity yet manages to show its beauty because of the stars and planets and nebulas 🌌💙. I absolutely love his work on the colours, he makes the cosmos looks bright and dreamlike and so hopeful !!

Alexei Leonov was also captain during the Apollo-Soyuz mission, ten years later in July 1975.
