Under bright-blue morning skies, China launched its first crewed space mission in five years Thursday, sending three science-minded military pilots rocketing to a new orbiting station they’re expected to reach around midafternoon.

The astronauts, already wearing their spacesuits, were seen off by space officials, other uniformed military personnel and a crowd of children waving flowers and flags and singing patriotic songs. The three gave final waves to a crowd of people waving flags, then entered the elevator to take them to the spaceship at the Jiuquan launch center in northwestern China.

The astronauts are traveling in the Shenzhou-12 spaceship launched by a Long March-2F Y12 rocket that blasted off shortly after the target time of 9:22am (6:52am IST) with near-perfect visibility at the launch center on the edge of the Gobi Desert.

The two veteran astronauts and a newcomer making his first space flight are scheduled to stay three months in the Tianhe, or Heavenly Harmony, conducting experiments, testing equipment, and preparing the station for expansion before two laboratory modules are launched next year.

The rocket dropped its boosters about two minutes into the flight followed by the coiling surrounding Shenzhou-12 at the top of the rocket. After about 10 minutes it separated from the rocket’s upper section, extended its solar panels and shortly afterward entered orbit.

About a half-dozen adjustments will take place over the next four to six hours to line up the spaceship for docking with the Tianhe at about 4pm (1:30pm IST), the mission’s deputy chief designer, Gao Xu, told state broadcaster CCTV.

The travel time is down from the two days it took to reach China’s earlier experimental space stations, a result of a “great many breakthroughs and innovations” Gao said.

“So the astronauts can a have a good rest in the space which should make them less tired,” Gao said.

Other improvements include an increase in the number of automated and remote-controlled systems that should “significantly lessen the pressure on the astronauts,” Gao said.

The mission brings to 14 the number of astronauts China has launched into space since its first crewed mission in 2003, becoming only the third country after the former Soviet Union and the United States to do so on its own. Two astronauts on those past missions were women, and while this first station crew is all male, women are expected to be part of future station crews.

The mission is the third of 11 planned through next year to add the additional sections to the station and send up crews and supplies. A fresh three-member crew and a cargo ship with supplies will be sent in three months.

China is not a participant in the International Space Station, largely as a result of US objections to the Chinese programs secrecy and close military ties. However, China has been stepping up cooperation with Russia and a host of other countries, and its station may continue operating beyond the International Space Station, which is reaching the end of its functional life.

China landed a probe on Mars last month that carried a rover, the Zhurong, and earlier landed a probe and rover on the moon’s less explored far side and brought back the first lunar samples by any country’s space programme since the 1970s.

After the Tianhe was launched in April, the rocket that carried it into space made an uncontrolled reentry to Earth, though China dismissed criticism of the potential safety hazard. Usually, discarded rocket stages reenter the atmosphere soon after liftoff, normally over water, and don’t go into orbit.

The rocket used Thursday is of a different type and the components that will reenter are expected to burn up long before they could be a danger, said Ji Qiming, assistant director of the China Manned Space Agency.

ISRO Unveils World’s Largest 10-Tonne Vertical Mixer for Solid Propellants

A significant advancement in India’s space technology has been achieved with the development of a 10-tonne vertical planetary mixer, the largest globally for solid propellant production. Designed and manufactured through a collaboration between the Indian Space Research Organisation (ISRO) and the Central Manufacturing Technology Institute (CMTI), this new equipment is expected to enhance efficiency and safety in the manufacturing of solid rocket motors. The handover ceremony took place on February 13 at CMTI, Bengaluru, where Satish Dhawan Space Centre (SDSC) Director A. Rajarajan received the mixer in the presence of ISRO Chairman S. Somanath and CMTI Director K. Prasad.

Enhancing Solid Propellant Production

As reported by ISRO, according to ISRO, the new vertical planetary mixer is a critical addition to India’s space propulsion systems. Solid propellants, which serve as the backbone of rocket motors, require precise and controlled mixing due to the sensitivity of the materials involved. The newly developed mixer, weighing approximately 150 tonnes with dimensions of 5.4 metres in length, 3.3 metres in breadth, and 8.7 metres in height, will improve the consistency, quality, and scalability of solid propellant production.

Towards Self-Reliance in Space Technology

As part of India’s push for self-reliance in critical technologies, the Department of Space has undertaken multiple initiatives to develop indigenous manufacturing capabilities. The realisation of this mixer underscores India’s increasing capability in aerospace engineering and manufacturing. The equipment has undergone successful factory-level acceptance tests and is set to play a key role in advancing the country’s space transportation systems.

Future Implications for ISRO’s Missions

With an emphasis on improving safety and productivity, the newly developed mixer is expected to streamline the process of solid propellant preparation for future ISRO missions. The technology is set to support upcoming launch vehicle developments, reinforcing India’s position in the global space industry.

NASA Lowers Risk of Asteroid 2024 YR4 Impact, Now Just 0.28 percent Chance

Concerns regarding asteroid 2024 YR4 have diminished, as NASA has revised the probability of its impact on Earth in 2032 from 1 in 32 to 1 in 360. The asteroid, which has an estimated diameter of 55 meters, was initially considered the most hazardous object on NASA’s Center for Near Earth Object Studies (CNEOS) Sentry Risk Table. New observational data gathered between February 18 and February 20 led to a reassessment, significantly lowering the projected threat level. According to NASA, the asteroid now holds a 99.72 percent chance of missing Earth entirely.

Orbital Data Leads to Reassessment

According to information provided by NASA, the latest findings were based on additional telescope observations, refining previous predictions. The data confirmed that the asteroid’s trajectory has been better understood, resulting in its classification at Level 1 on the Torino Scale, a system used to gauge the risk posed by near-Earth objects. Richard Binzel, the creator of the Torino Scale, told Space.com that further observations are expected to move 2024 YR4 to Level 0, indicating no cause for concern.

Comparisons with Other Asteroids

Despite the significant drop in risk, asteroid 2024 YR4 remains at the top of the Sentry Risk Table. The next most concerning object is 1950 DA, with a 0.039 percent chance of impacting Earth in the year 2880. Experts have emphasized that continued monitoring will provide further clarity on the asteroid’s path as it makes another approach in 2028.

Scientific Observations and Future Monitoring

David Rankin, an astronomer from the Catalina Sky Survey, explained that minor variations in measurement precision can cause large shifts in projected trajectories. Speaking to Space.com, he noted that uncertainties in an asteroid’s position are similar to moving a long stick slightly at one end, causing dramatic shifts at the other. Rankin reassured that further data collection would likely continue to reduce any remaining impact probability.

NASA has also noted a minor possibility that 2024 YR4 could impact the Moon, but the likelihood remains low. As the asteroid moves away from Earth, it will not be visible again to ground-based telescopes until 2028, when additional observations will refine its projected path. Scientists remain confident that its most probable outcome is to continue its orbit around the Sun without incident.
