Science News Roundup: North Korea's first spy satellite is 'alive', can manoeuvre, expert says; US spacecraft and Russian satellite to pass dangerously near each other, NASA says and more

Texas-based Intuitive Machines said in an online update on Tuesday that its control center in Houston remained in contact with the lander as it "efficiently sent payload science data and imagery in furtherance of the company's mission objectives." North Korea's first spy satellite is 'alive', can manoeuvre, expert says North Korea's first spy satellite is "alive", a Netherlands-based space expert said on Tuesday, after detecting changes in its orbit that suggested Pyongyang was successfully controlling the spacecraft - although its capabilities remain unknown.

Following is a summary of current science news briefs.

Odysseus moon lander still operational, in final hours before battery dies

Odysseus, the first U.S. spacecraft to land on the moon since 1972, neared the end of its fifth day on the lunar surface still operational, but with its battery in its final hours before the vehicle is expected to go dark, according to flight controllers. Texas-based Intuitive Machines said in an online update on Tuesday that its control center in Houston remained in contact with the lander as it "efficiently sent payload science data and imagery in furtherance of the company's mission objectives."

North Korea's first spy satellite is 'alive', can manoeuvre, expert says

North Korea's first spy satellite is "alive", a Netherlands-based space expert said on Tuesday, after detecting changes in its orbit that suggested Pyongyang was successfully controlling the spacecraft - although its capabilities remain unknown. After two fiery failures, North Korea successfully placed the Malligyong-1 satellite in orbit in November. Pyongyang's state media claimed it has photographed sensitive military and political sites in South Korea, the United States and elsewhere, but has not released any imagery. Independent radio trackers have not detected signals from the satellite.

US spacecraft and Russian satellite to pass dangerously near each other, NASA says

The U.S. Department of Defense is monitoring a close pass between NASA's Thermosphere Ionosphere Mesosphere Energetics and Dynamics Mission (TIMED) spacecraft and the Russian Cosmos 2221 satellite, NASA said in a blog post early Wednesday. Although the spacecraft are expected to miss each other, a collision could result in significant debris, the U.S. space agency said, adding that it was continuing to monitor the situation with the Department of Defense. The statement did not say how close the spacecraft would come to each other.

India announces four-member crew for 'Gaganyaan' space mission

India on Tuesday introduced four crew members for its maiden 'Gaganyaan' space voyage, as it aims to become the world's fourth country to send a crewed mission into space just months after a historic landing on the south pole of the moon. Gaganyaan, or "sky craft" in Hindi, is the first mission of its kind for India and will cost about 90.23 billion rupees ($1.1 billion). It involves the launch of a habitable space capsule over the next year to an orbit of 400 km (250 miles) and its return via a landing in the Indian Ocean.

China's latest Long March rocket to debut in year of record missions

China's Long March 12, capable of sending bigger satellites with more functionalities into the Earth's orbit, is expected to make its debut flight in 2024, in a year of record launch missions for the country, state media reported on Monday.

Propelled by six liquid oxygen-kerosene-fueled engines, the Long March 12 will be able to transport a payload of 10,000 kg (22,000 pounds) to a low-Earth orbit, according to the Shanghai Academy of Spaceflight Technology, a subsidiary of China's main space contractor.

Astronomers observe scar on white dwarf 'cannibal' star

A slowly cooling stellar ember called a white dwarf with a scar on its face is providing new insight into the behavior of certain "cannibal" stars at the end of their life cycle. Using the European Southern Observatory's Chile-based Very Large Telescope, researchers studied a white dwarf located about 63 light years from Earth. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Like all white dwarfs, it is incredibly dense, packing about 70% of the sun's mass into an Earth-sized object.

Factbox-Moon landing puts new space race startups in spotlight

Interest in space startups has spiked after Intuitive Machines became the first private firm to successfully land a spacecraft on the moon, in the first U.S. touchdown on the lunar surface in more than half a century. Though the lander tipped sideways on the lunar surface, the company is likely to complete its mission and prove the capabilities of such startups.

Moon lander Odysseus mission to be cut short after sideways touchdown

Flight control engineers expect to lose contact with the private U.S. moon lander Odysseus on Tuesday morning, cutting short the mission five days after its sideways touchdown, the company behind the spacecraft, Intuitive Machines, said on Monday. It remained to be seen how much scientific data might be lost as a result of the shortened lifespan of Odysseus, which according to previous estimates from the company and its biggest customer, NASA, was supposed to operate on the moon for seven to 10 days.
