A radiation protection vest, olive oil, and sutured tissues are among the scientific samples returning from the International Space Station on the 26th SpaceX commercial resupply services mission for NASA. The Dragon spacecraft, which arrived at the station Nov. 27, is scheduled to undock on January 9, with splashdown January 11 off the coast of Florida.

The cargo returns to NASA's Kennedy Space Center in Florida, where scientists can make additional observations and analyses of their experiments before the effects of gravity fully kick back in. Many also conduct more in-depth analysis later in their home labs.

China's National Space Administration (CNSA) has been hoping to reestablish communications with the Zhurong Mars rover, but so far, their efforts have been unsuccessful. Zhurong was put into hibernation over six months ago as it hunkered down in attempts to survive the Martian winter.

But it's been a tough winter in Utopia Planetia in Mars northern hemisphere where Zhurong is located. Not only were the temperatures extremely low, colder than -100°C (-148°F), but a regional dust storm severely reduced the likelihood of the rover collecting any power with its solar panels. This is the same dust storm that has hastened the end of NASA's Mars InSight mission.

According to the South China Morning Post, the mission team predicted Zhurong would resume operations around December 26 as the planet's northern hemisphere entered its spring season and environmental conditions improved.

Space sector bosses on Tuesday said they were disappointed by the failure of the country's historic first attempt to launch satellites from UK soil but pledged to investigate and try again.

The failure of the mission late on Monday is a blow to the UK's fledgling space sector.

Had it been successful, it would have made the UK one of only nine countries able to launch rockets into Earth's orbit.

A Virgin Orbit Boeing 747 carrying the 70-foot (21-metre) rocket took off from a spaceport in Cornwall, southwest England, at 2202 GMT on Monday.

The rocket then detached from the aircraft and ignited as planned at a height of 35,000 feet over the Atlantic Ocean to the south of Ireland at around 2315 GMT.

But as the rocket was due to enter orbit and discharge its nine satellites, scientists reported an "anomaly" that prevented it from reaching orbit.

Virgin Orbit CEO Dan Hart praised the launch teams but said their task had been complicated by the "first time nature of this mission" which had "added layers of complexity".

"We will work tirelessly to understand the nature of the failure, make corrective actions and return to orbit as soon as we have completed a full investigation and mission assurance process," he added.
