SHANGHAI (Reuters) – China’s Tiangong-1 space station re-entered the earth’s atmosphere and burnt up over the South Pacific on Monday, the Chinese space authority said.

The “vast majority” of the craft burnt up on re-entry, at around 8:15 a.m. (0015 GMT), the authority said in a brief statement on its website, without saying exactly where any pieces might have landed.

Brad Tucker, an astrophysicist at Australian National University, said the remnants of Tiangong-1 appeared to have landed about 100 km (62 miles) northwest of Tahiti.

“Small bits definitely will have made it to the surface,” he told Reuters, adding that while about 90 percent would have burnt up in the atmosphere and just 10 percent made it to the ground, that fraction still amounted to 700 kg (1,543 lb) to 800 kg (1,764 lb).

“Most likely the debris is in the ocean, and even if people stumbled over it, it would just look like rubbish in the ocean and be spread over a huge area of thousands of square kilometers.”

China said on Friday it was unlikely any large pieces would reach the ground.

The United States Air Force 18th Space Control Squadron, which tracks and detects all artificial objects in Earth’s orbit, said it had also tracked the Tiangong-1 in its re-entry over the South Pacific.

It said in a statement it had confirmed re-entry in coordination with counterparts in Australia, Canada, France, Germany, Italy, Japan, South Korea and Britain.

The 10.4-metre-long (34.1-foot) Tiangong-1, or “Heavenly Palace 1”, was launched in 2011 to carry out docking and orbit experiments as part of China’s ambitious space program, which aims to place a permanent station in orbit by 2023.Decommissioning was originally planned for 2013 but the mission was repeatedly extended.

Asked about the space station, Chinese foreign ministry spokesman Geng Shuang told a regular briefing he had no other information and reiterated that China had been reporting the situation to the U.N. space agency in an open and transparent way.

“According to what I understand, at present there has not been found any damage on the ground,” he said, without elaborating.

China had earlier said re-entry would happen in late 2017, but that process was delayed, leading some experts to suggest the space laboratory was out of control.

Worldwide media hype about the re-entry reflected overseas “envy” of China’s space industry, the Chinese tabloid Global Times said on Monday.

“It’s normal for spacecraft to re-enter the atmosphere, yet Tiangong-1 received so much attention, partly because some Western countries are trying to hype and sling mud at China’s fast-growing aerospace industry,” it said.

China tests self-sustaining space station in Beijing

BEIJING (Reuters) – Sealed behind the steel doors of two bunkers in a Beijing suburb, university students are trying to find out how it feels to live in a space station on another planet, recycling everything from plant cuttings to urine.

They are part of a project aimed at creating a self-sustaining ecosystem that provides everything humans need to survive.

Four students from Beijing University of Aeronautics and Astronautics entered the Lunar Palace-1 on Sunday with the aim of living self-sufficiently for 200 days.

They say they are happy to act as human guinea-pigs if it means getting closer to their dream of becoming astronauts.

“I’ll get so much out of this,” Liu Guanghui, a PhD student, who entered the bunker on Sunday, said. “It’s truly a different life experience.”

President Xi Jinping wants China to become a global power in space exploration, with plans to send the first probe to the dark side of the moon by 2018 and to put astronauts on the moon by 2036. The Lunar Palace 365 experiment may allow them to stay there for extended periods.

For Liu Hong, a professor at Beijing University of Aeronautics and Astronautics and the project’s principal architect, said everything needed for human survival had been carefully calculated.

“We’ve designed it so the oxygen (produced by plants at the station) is exactly enough to satisfy the humans, the animals, and the organisms that break down the waste materials,” she said.

But satisfying physical needs is only one part of the experiment, Liu said. Charting the mental impact of confinement in a small space for such a long time is equally crucial.

“They can become a bit depressed,” Liu said. “If you spend a long time in this type of environment it can create some psychological problems.”

Liu Hui, a student leader who participated an initial 60-day experiment at Lunar Palace-1 that finished on Sunday, said that she sometimes “felt a bit low” after a day’s work.

The project’s support team has found mapping out a specific set of daily tasks for the students is one way that helps them to remain happy.

But the 200-day group will also be tested to see how they react to living a for period of time without sunlight. The project’s team declined to elaborate.

“We did this experiment with animals… so we want to see how much impact it will have on people,” Liu, the professor, said.

Astronauts get first look inside space station’s inflatable module

The Bigelow Expandable Activity Module shown at Bigelow Aerospace in Las Vegas Nevada

By Irene Klotz

CAPE CANAVERAL, Fla. (Reuters) – Astronauts aboard the International Space Station on Monday floated inside an experimental inflatable module that will test a less expensive and potentially safer option for housing crews during long stays in space, NASA said.

Station flight engineers Jeff Williams and Oleg Skripochka opened the hatch to the Bigelow Expandable Activity Module, or BEAM, at 4:47 a.m. EDT (0847 GMT) on Monday.

Designed and built by privately-owned Bigelow Aerospace, BEAM is the first inflatable habitat to be tested with astronauts in space. The Las Vegas-based firm previously flew two unmanned prototypes.

BEAM was flown to the space station aboard a SpaceX Dragon cargo ship in April and inflated to the size of small bedroom on May 28. It is scheduled to remain attached to the station, a $100 billion research laboratory that flies about 250 miles (400 km) above Earth, for two years. Wearing face masks and headlamps, Williams and Skripochka floated inside the darkened module for the first time to collect air samples for analysis and retrieve engineering data from BEAM’s inflation.

Williams told flight controllers the module looked “pristine,” mission commentator Gary Jordan said during a NASA TV broadcast. Williams also said it was cold inside BEAM, but that there was no sign of condensation on the walls, Jordan said.

Astronauts will return to BEAM on Tuesday and Wednesday to install temperature and radiation sensors as well as instruments to collect data from any micro-meteoroid or orbital debris impacts.

BEAM’s hatch will remain closed except when astronauts go inside the module six or seven times per year to retrieve recorded data, NASA said.

Lightweight inflatables, which are made of layers of fabrics and a protective outer shield, are far less costly to launch than traditional metal modules. They may also provide astronauts with better radiation protection.

“This technology can be used in future designs for a mission to Mars,” Jordan said. Bigelow Aerospace is aiming to fly inflatable space modules 20 times larger than BEAM that can be leased out to companies and research organizations.
