First 3D-printed rocket fails to reach orbit: achieving this milestone “would have been unprecedented », Magnate Daily

The first 3D-printed rocket successfully lifted off from Cape Canaveral, Florida, on Wednesday, but failed to reach orbit due to an “anomaly” during second stage separation, according to a live broadcast.
 
This new setback follows two previous tests cancelled at the last minute due to technical problems. This mission, named “Good luck, have fun”, was closely watched, as 3D printed rockets could represent a small revolution in the launch industry.
The Terran 1 rocket, from California-based startup Relativity Space, was to collect data and demonstrate that a 3D printed rocket could withstand the rigors of takeoff and space flight. In total, 85% of the rocket’s mass was 3D printed, and the company is targeting 95% in the future.
The main advantage of the technique is that it greatly simplifies the manufacturing process and thus reduces costs.
 
Terran 1 is 33.5 meters high and just over 2 meters in diameter. Its first stage has nine engines, also 3D printed. Its objective is to be able to place 1250 kg in low earth orbit (small satellites, for example), which makes it a light launcher.
 
After the separation of the first stage of the rocket, the second stage should have continued its route until reaching the earth orbit, eight minutes after the takeoff. To succeed in this step from the first flight would have been “unprecedented”, said Tim Ellis.
 
The rocket uses methalox as fuel, a mixture of liquid oxygen and liquefied natural gas (essentially methane). If it had succeeded in reaching the orbit, it would be the first rocket using this fuel to do so.
 
Relativity Space, which promotes the long-term vision of humanity living on multiple planets, argues that this is the “fuel of the future” and the easiest to produce on Mars. United Launch Alliance’s (ULA) Vulcan and SpaceX’s Starship rockets in development are also expected to use this fuel.

China sends its first civilian astronaut into space

The three astronauts’ stay is scheduled to last six months, and marks a new stage in the progress of Beijing’s space program.
 
On Tuesday May 30, China sent three new astronauts to its Tiangong space station, including for the first time a civilian. This is a valuable experience for the Asian giant, which has reaffirmed its desire to send a Chinese astronaut to the Moon by 2030, a major objective of a space program that has been progressing steadily for several decades.
 
The trio on the Shenzhou-16 mission lifted off aboard a Long March 2F rocket at 9:31 a.m. local time from the Jiuquan launch center in the Gobi Desert, according to AFP reporters on site. The launch was a “total success” and the “astronauts are in good shape”, said Zou Lipeng, director of the launch center.
 
Mission commander, veteran engineer Jing Haipeng, on his fourth space flight, is accompanied by engineer Zhu Yangzhu and Gui Haichao, a professor and the first Chinese civilian in space. A specialist in space science and engineering, Haichao will be in charge of experiments on the station. He does not come from the armed forces, as has always been the case until now. Their stay in Tiangong (“Heavenly Palace” in Chinese) is scheduled to last six months.

North Korea confirmed on Tuesday that it will launch a military spy satellite in June, in order to “confront dangerous US military actions”, according to the official KCNA agency.
The “military reconnaissance satellite number 1” will be “launched in June”, in order to “confront the dangerous military actions of the United States and its vassals”, according to Ri Pyong Chol, vice-chairman of the ruling party’s Central Military Commission, quoted by KCNA.
On Monday, Japan announced that it had been informed by North Korea of a forthcoming satellite launch, a project which the Japanese government believed to conceal a ballistic missile launch.
According to Tokyo, Pyongyang has told the Japanese coastguard that a rocket will be launched between May 31 and June 11, and is expected to land in an area near the Yellow Sea, the East China Sea and east of Luzon Island in the Philippines.
North Korea has already tested ballistic missiles in 2012 and 2016, which it described as satellite launches and which flew over the island department of Okinawa in southern Japan.
The development of a reconnaissance satellite was one of Pyongyang’s key defense projects unveiled last year by Kim Jong Un.

On Tuesday, China will send a civilian astronaut into space for the first time in its history on a manned mission to the Tiangong space station, the China Human Spaceflight Agency announced.

 

This astronaut, Gui Haichao, a “payload specialist”, is “a professor at the Beijing University of Aeronautics and Astronautics”, Lin Xiqiang, spokesman for the space agency, told a press conference on Monday.

Until now, all Chinese astronauts who have launched into space have been members of the People’s Liberation Army.

 

Mr. Gui will be “mainly responsible for in-orbit management of payloads” dedicated to space science experiments, the spokesman said.

The civilian astronaut will orbit alongside Shenzhou-16 mission commander Jing Haipeng and astronaut Zhu Yangzhu.

 

The crew is due to take off from the Jiuquan launch base in northwest China at 09:31 local time, according to the space agency.

Projects linked to China’s “space dream” are multiplying under the presidency of Xi Jinping.

 

The Asian giant has been investing billions of euros in its military-led space program for several decades, enabling it to make up most of the ground lost to the Americans and Russians.

China sent its first astronaut into space in 2003, and its Tiangong (“Celestial Palace”) space station has been fully operational since late 2022. In 2019, a Chinese spacecraft landed on the far side of the Moon. Then, in 2021, China landed a small robot on the surface of Mars. China plans to send its first crew to the Moon by 2029.
