The developer of a space rocket fuel based on liquid hydrogen which made moon flights possible, Barys Kit, has died at the age of 107. The Belarusian-American rocket scientist was one of the world’s oldest men.

“Bring no harm to others and you'll be happy in life”

Coming from the small Belarusian village of Aharodniki, Kit became a world-famous scientist in the field of Astronautics. He held positions including Honorary Professor of the University of Maryland (USA) and Vice-President of the Eurasian International Astronautics Academy. He was also a long-standing member of the American Institute of Aeronautics and Astronautics, the British Interplanetary Society, and the International Academy of Astronautics in Paris.

Reporter, Hanna Aranovich met the scientist before his death, as he recounted just a few anecdotes from over a century of stories.

Kit grew up under Polish rule during the interwar period, drawing the attention of the authorites while he was still in school and even being arrested as a result of his student activities. He went on to become a village teacher.

After the German invasion during the Second World War he was stopped by a patrol carrying parcels of food. After being searched, he was found to be carrying a number of German travel passes which was enough to convict him of involvement with the resistance movement. A death sentence was inevitable

“I spent 30 days in a German prison,” he recalled. “Every day I was waiting for death. It was the Gestapo. There were 30 people in the cell. Every morning German police came and chose random people to be shot. I survived. 30 times I was waiting for death to happen…”

By pure luck, a former student, Kastus Kasyak, managed to secure his freedom. Kasyak would later be hanged by the Soviets.

As the war came to an end, Kit too, was accused of collaboration because of his public role as a schoolteacher. He, however, managed to flee, making his way to friends in America.

There, at a party, he was introduced to a professor, Hustau Makshitsky, who managed to get him his first job in science, at North American Aviation.

By 1960, Kit had become an expert in his field and published the first ever book on fuel for rocket systems, the "Rocket Propellant Handbook". It was rapidly recognised as a reference work for the industry and read across the world.

From 1963 he worked at the Astronautics Bureau of the International Telephone and Telegraph Corporation. At the same time, American astronauts were preparing to fly to the Moon.

His best-known achievement was his work with liquid Hydrogen, developing a groundbreaking rocket fuel formula. It was this which allowed the first American flight to the moon to take place. It became the basis for many other scientists’ future research.

The name of ‘Barys Kit’ was included inside a time capsule honouring the world’s greatest space scientists, which was built into a wall of the US Capitol building in Washington DC. The capsule is intended to be opened in 500 years.

He returned to Germany in 1972 to be nearer to his homeland, retiring at the age of 82.

Kit spent his final years in a nursing home in Frankfurt-am-Mein, Germany. Even into the final days of his life he could speak 4 languages fluently: English, Belarusian, Russian and German. In his tiny room, he always displayed an American flag, a big photo of his family on the windowsill and a pile of awards on the shelf.

Due to his views on the government in his homeland, Belarus, his status was rarely recognised in the state-run media.

But that didn’t stop him remaining positive about life,

“Bring no harm to others and you'll be happy in life.”

Per NASA's [LIQUID HYDROGEN AS A PROPULSION FUEL,1945-1959 (https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19790008823.pdf):

Tsiolkovskiy:

From what was known about heats of combustion by the start of the twentieth century, it is not at all surprising that Tsiolkovskiy became the first to propose the use of liquid hydrogen and oxygen to propel a rocket, which he did in his classic "Exploration of the Universe with Reaction Machines," first published in 1903 ... Using Newton's relationship between potential and kinetic energy, Tsiolkovskiy calculated the exhaust jet velocity of a liquid hydrogen-liquid oxygen rocket as 5700 meters per second.

Goddard:

In a report to the Smithsonian in 1920, Goddard pointed out that liquid hydrogen and solid oxygen had greater capability than smokeless powder for lunar and planetary missions.

Oberth:

Later, in discussing a design for a mail rocket, he [Hermann Oberth] observed: "For example, with a correctly built oxygen-hydrogen nozzle I achieved a burn lasting 21 minutes." In describing another design in 1929, however, he stated: "Unfortunately, I have not yet been able to experiment with liquid hydrogen."

All three of these early pioneers understood and described the advantages of using liquid-hydrogen. and in the case of Oberth even built and tested a hydrogen-oxygen but ran into practical challenges in working with liquid hydrogen. No mention of Barys Kit anywhere in this 325 page history.

And strangely, Barys Kit's wikipedia page doesn't mention anything about him "inventing" liquid hydrogen; what it says is, "Kit is the author of the first manual on rocket propellant "Rocket Propellant Handbook", published by McMillan in 1960". It also states that Kit began his scientific activities in the field of astronautics in the mid-1950s.

The problem for the "Kit invented the liquid hydrogen rocket" was that the US was already experimenting with liquid-hydrogen rocket engines by 1954. Again, Per LIQUID HYDROGEN AS A PROPULSION FUEL,1945-1959 (https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19790008823.pdf).

When the rocket subcommittee met in October 1954, preparations for the first experiment with liquid hydrogen were almost complete. The liquefier was producing liquid hydrogen. One of the larger test cells had been equipped to use liquid hydrogen with either of two oxidizers-liquid oxygen or liquid fluorine. Edward Rothenberg headed the team using hydrogen-oxygen and was ready first.* On 23 November 1954, the first successful run with liquid hydrogen was made; thrust and chamber pressure were at design values and exhaust velocity was 90 percent of theoretical. Ten days later, two more successful runs were made, but performance data were incomplete. A fourth successful run on 6 January 1955 yielded lower performance than the previous runs.

So I'm sure Kit made significant contributions in the 25 years he worked for the US space program, but he wasn't -- by any measure -- the inventor of H2 liquid rocket fuel.

For the record, there's no info stating he directly invented hydrogen rocket fuel. Instead he wrote the book detailing every type of rocket fuel there is, which is apparently still used today. Here's a Short Biography and an Interview.

He invented the formula for hydrogen based rocket fuel?

They mean H2?
