His most famous work, "" (''Issledovanie mirovikh prostranstv reaktivnimi priborami'', or ''The Exploration of Cosmic Space by Means of Reaction Devices''), was published in 1903, but this theoretical work was not widely influential outside Russia.

's account, Opel RAK rocket designer, Friedrich Wilhelm Sander launched two liquid-fuel rockets at Opel Rennbahn in Rüsselsheim on April 10 and April 12, 1929. These Opel RAK rockets have been the first European, and after Goddard the world's second, liquid-fuel rockets in history. In his book “Raketenfahrt” Valier describes the size of the rockets as of 21 cm in diameter and with a length of 74 cm, weighing 7 kg empty and 16 kg with fuel. The maximum thrust was 45 to 50 kp, with a total burning time of 132 seconds. These properties indicate a gas pressure pumping. The first missile rose so quickly that Sander lost sight of it. Two days later, a second unit was ready to go, Sander tied a 4,000-meter-long rope to the rocket. After 2000 m or rope had been unwound, the line broke and this rocket also disappeared in the area, probably near the Opel proving ground and racetrack in Rüsselsheim, the "Rennbahn". The main purpose of these tests was to develop the propulsion system for the aircraft for crossing the English channel. Also spaceflight historian

is quoted as saying: "Sander and I now want to transfer the liquid rocket from the laboratory to practical use. With the liquid rocket I hope to be the first man to thus fly across the English Channel. I will not rest until I have accomplished that." At a speech on the donation of a RAK 2 replica to the Deutsches Museum, von Opel mentioned also Opel engineer Josef Schaberger as a key collaborator. "He belonged," von Opel said, "with the same enthusiasm as Sander to our small secret group, one of the tasks of which was to hide all the preparations from my father, because his paternal apprehensions led him to believe that I was cut out for something better than being a rocket researchist. Schaberger supervised all the details involved in construction and assembly (of rocket cars), and every time I sat behind the wheel with a few hundred pounds of explosives in my rear, and made the first contact, I did so with a feeling of total security ..As early as 1928, Mr. Schaberger and I developed a liquid rocket, which was definitely the first permanently operating rocket in which the explosive was injected into the combustion chamber and simultaneously cooled using pumps. ..We used benzol as the fuel," von Opel continued, "and nitrogen tetroxide as the oxidizer. This rocket was installed in a Mueller-Griessheim aircraft and developed a thrust of 70 kg (154 lb.)." By May 1929, the engine produced a thrust of 200 kg (440 lb.) "for longer than fifteen minutes and in July 1929, the Opel RAK collaborators were able to attain powered phases of more than thirty minutes for thrusts of 300 kg (660-lb.) at Opel's works in Rüsselsheim," again according to Max Valier's account. The Great Depression brought an end to the Opel RAK activities. Valier's, who died while experimenting in 1930, and Sander's work on liquid-fuel rockets was confiscated by the German military, the

Japan

Japan's space agency, the Japan Aerospace Exploration Agency, is a major space player in Asia. While not maintaining a commercial launch service, Japan has deployed a module in the ISS and operates an uncrewed cargo spacecraft, the H-II Transfer Vehicle. JAXA has plans to launch a Mars fly-by probe. Their lunar probe, SELENE, is touted as the most sophisticated lunar exploration mission in the post-Apollo program, Apollo era. Japan's Hayabusa probe was mankind's first sample return from an asteroid. IKAROS was the first operational solar sail. Although Japan developed the HOPE-X, Kankoh-maru, and Fuji (Spacecraft), Fuji crewed capsule spacecraft, none of them have been launched. Japan's current ambition is to deploy a new crewed spacecraft by 2025 and to establish a Moon base by 2030.

ISRO

Indian Space Research Organisation, India's national space agency, maintains an active space program. It operates a small commercial launch service and launched a successful uncrewed lunar mission dubbed Chandrayaan-1 in October 2007. India has successfully launched an interplanetary mission, Mars Orbiter Mission, in 2013 which reached Mars in September 2014, hence becoming the first country in the world to do a Mars mission in its maiden attempt. On July 22, 2019, India sent Chandrayaan-2 to the Moon, whose ''Vikram'' lander crashed on the lunar south pole region on September 6.


Other nations

Private Companies


SpaceX (USA)

SpaceX is also planning a Reusable launch system, fully reusable rocket named SpaceX Starship, Starship. It consists of a first stage named SpaceX_Starship#Super_Heavy_booster, Super Heavy and a second stage also named Starship.


Blue Origin

Blue Origin made the first reusable space capable rocket booster, New Shepard (it is suborbital, Falcon 9 was the first orbital). They also originally had the idea of landing rocket boosters on ships at sea, however SpaceX replicated their idea and did it first. They lead the national team, which is designing a lunar lander and transfer vehicle (Integrated Lander Vehicle). They will contribute by modifying their Blue Moon (spacecraft), Blue Moon lunar lander.


Bigelow Aerospace

Bigelow Aerospace made the first commercial module in space (BEAM). They also designed and manufactured the first inflatable habitats in space (''Genesis I'' and ''Genesis II (space habitat), Genesis II''). They also plan to make the first commercial space station around the moon (Lunar Depot), perhaps the first ever.


Northrop Grumman

They make commercial resupply runs to the ISS with their Cygnus (spacecraft), Cygnus spacecraft. They also helped develop non-commercial spacecraft during the space race (Apollo Lunar Module, Apollo LM as Grumman). They also are a part of the national team, lead by Blue Origin which is designing a lunar lander and transfer vehicle (Integrated Lander Vehicle), partly based on Cygnus.
