A collaborative effort between China and France has taken flight! On Saturday, the Space Variable Objects Monitor (SVOM) was launched into orbit, marking a huge leap in our ability to study gamma-ray bursts, the most powerful explosions in the universe.

The China-constructed SVOM has scientific instruments from both nations

This state-of-the-art spacecraft is a marvel of international collaboration. Constructed by China, SVOM carries scientific instruments from both nations. French contributions include the ECLAIRs coded mask camera and the Microchannel X-ray Telescope, while China provides the Gamma-ray Burst Monitor and the Visible Telescope.

Gamma-ray bursts are short-lived, incredibly energetic explosions that originate from distant galaxies. Since their accidental discovery in 1967, these cosmic mysteries have fascinated astronomers. SVOM’s mission is to unravel their secrets.

SVOM isn’t the first spacecraft dedicated to gamma-ray bursts. Missions like NASA’s Compton Gamma Ray Observatory and Italy’s BeppoSAX have paved the way. However, SVOM boasts the most sophisticated suite of instruments ever assembled for this purpose.

SVOM’s scientific goals extend beyond gamma-ray bursts. By studying these powerful events, scientists hope to gain insights into dark energy, the evolution of the universe, and even the elusive connection between gravitational waves and electromagnetic signals.

SVOM isn’t just a scientific achievement; it’s a testament to successful international cooperation in space exploration. Following the China-France Oceanography Satellite launched in 2018, SVOM marks another chapter in this productive partnership. The data collected by SVOM promises to benefit scientists from both nations and push the boundaries of our understanding of the universe.

The Indian Space Research Organisation (ISRO) recently had a successful spacecraft launch, which took the country to the moon. Chandrayaan-3 landed on the moon’s south pole last month, but it appears that India is showing no signs of stopping its venture into space. A mere week after the successful moon landing, the country has now launched another new spacecraft that is setting its sights on the Sun.

India launches Aditya-L1: First Indian mission to observe the Sun

The nation’s space agency has already launched a rocket carrying Aditya-L1, which is India’s first mission dedicated to observing the Sun. For its mission, Aditya-L1 will be traveling over 930,000 miles over four months until it reaches the L1 Lagrange Point. For those unaware, this point is a place of equilibrium between two massive orbiting bodies, which in this case is the Sun and planet Earth.

The new spacecraft will remain in orbit at this point and collect data. Scientists are hoping that the information gathered by this mission will help them answer why the Sun’s corona is hotter than the surface. The data could even help provide information on how solar radiation and various solar phenomena affect communication systems, satellites, and power grids.

Scientists are hoping that Aditya-L1 may even reveal crucial information regarding solar wind behavior and its impacts on Earth’s climate. According to Sankar Subramanian, the mission’s principal scientist, “We have made sure we will have a unique data set that is not currently available from any other mission. This will allow us to understand the sun, its dynamics as well as the inner heliosphere, which is an important element for current-day technology, as well as space-weather aspects.”

Chandrayaan-3 Mission

An update on the Chandrayaan-3 mission revealed that the Vikram Lander has successfully soft-landed on the Moon again. It has exceeded its mission objectives and successfully underwent a hop experiment. The Vikram lander also performed well and deployed Ramp, ChaSTE, and ILSA that were folded back and redeployed successfully after their experiment.

China has begun the work for its first commercial spacecraft launch site at Wenchang in the southern island province of Hainan. 

There is already a state-owned launch center in Hainan called the Wenchang Space Launch Center, which is the fourth launch site in China. The other three are the Jiuquan Satellite Launch Center which was the country’s earliest base and where most launches and tests have been conducted to date, Taiyuan Launch Centre which is ideal for launching solar-synchronous satellites and Xichang Satellite Launch Center which is designed mainly to launch powerful thrust rockets and geostationary satellites. 

In China, a commercial space center refers to a site invested in and built by an entity other than the Government or Military. Hainan Commercial Space Launch Site program is a joint venture of the Hainan government and three space conglomerates－China Aerospace Science and Technology Corp, China Aerospace Science and Industry Corp, and China Satellite Network Group.

The work on the commercial launch site will be done by an affiliate of the China Aerospace Science and Technology Corporation. The estimated time for completion is one year and the site will be operational from 2024. The new launch site which covers an approximate area of 133 hectares, will have a launch pad, water spraying systems, lightning protection towers, hoisting equipment, transition transportation equipment, diversion devices, a fixed service tower, and more. 

Feng Fei, the provincial governor, of Wenchang said that Hainan will make full use of the new launch site to establish an entire space industry chain covering carrier rockets, satellites, and data processing businesses. He further added that the aim was to transform Wenchange into a world-class spaceport. 

The Wenchang Launch Center is China’s southernmost launch site and is chosen for its low latitude and closeness to the equator. 

If a spacecraft is launched from a site near the Equator, then it gets a natural speed boost caused due to Earth’s rotation, which in turn helps to reduce the cost of fuel and boosters. An optimal launch site needs to be at a coastal area near the equator as it maximizes the use of the earth’s rotational speed and gives an advantage of orientation that helps to arrive quickly at the geostationary orbit. 

Major Spacecraft Launch sites like Cape Canaveral, Vandenberg, and Sriharikota are all located near the coast. 

China’s Space Industry ranks second in the world just after the US. China National Space Administration (CNSA) has overseen the development of China’s space program which has launched ballistic missiles, artificial satellites, manned space flights, and the famous Tiangong Space station. The ambition of this Asian giant does not stop here as it plans to explore the entire solar system. 

With the development of a commercial launch site, China is now stepping into the commercial space era along with the US.
