China Successfully Launches Rocket from Sailing Ship into Space

The two satellites are expected to step up all-weather monitoring of ocean wind fields, improve typhoon monitoring and accuracy of the weather forecast in China

In a first, China on Wednesday successfully launched a rocket from a sailing ship into space, showcasing its prowess in the field.

A Long March-11 solid propellant carrier rocket blasted off at 12.06 p.m. from the mobile platform in the Yellow Sea off Shandong Province, Chinese news agency Xinhua reported.

It is China’s first space launch from a sea-based platform and the 306th mission of the Long March carrier rocket series, the state-owned news outlet said.

The Long March-11 can carry small satellites and can take multiple satellites into orbit at the same time.

The rocket carried two technology experiment satellites and five commercial satellites into space.

“The seaborne launch technology will meet the growing launch demand of low inclination satellites and help China provide launch services for countries participating in the Belt and Road Initiative,” experts were quoted as saying by Xinhua.

Human Sperm Retains Viability in Outer Space Conditions: Researchers

The study was presented at an annual meeting of European Society of Human Reproduction and Embryology in Vienna, Austria

Researchers have found that human sperm retains its complete viability within the different gravitational conditions found in outer space.

The results could be a huge boost to zillionaires like Amazon founder Jeff Bezos who see the “colonisation” of space as an answer to the Earth’s ever threatened resources.

“If the number of space missions increases in the coming years, and are of longer duration, it is important to study the effects of long-term human exposure to space in order to face them,” said Montserrat Boada from Dexeus Women’s Health in Barcelona, whose group worked with microgravity engineers from the Polytechnic University of Barcelona.

“It’s not unreasonable to start thinking about the possibility of reproduction beyond the Earth,” Boada said.

The study was performed using a small aerobatic training aircraft (CAP10), which can provide short-duration hypogravity exposure.

The plane executed a series of 20 parabolic manoeuvres, providing eight seconds of microgravity for each parabola.

Overall, 10 sperm samples obtained from 10 healthy donors were analysed after exposure to the different microgravities found in space and ground gravity.

To overcome regulatory constraints and increase donor numbers, sperm banks in the UK and Australia began to market the act of donating sperm as a confirmation of masculinity. Pixabay

The sperm analysis comprised a full range of measurements currently performed for fertility testing — concentration, motility, vitality, morphology and DNA fragmentation — and results found no difference whatsoever in any of the parameters between the microgravity space samples and the control group samples from Earth.

Indeed, there was 100 per cent concordance in DNA fragmentation rate and vitality, and 90 per cent concordance in sperm concentration and motility, said Boada.

These minor differences, she added, “were more probably related to heterogeneity of the sperm sample than to the effect of exposure to different gravity conditions”.

Boada described this as a preliminary study and her group will now move on to validate the results and then to larger sperm samples, longer periods of microgravity and even fresh sperm.

One reason for using frozen sperm in this study was the known effect of radiation on fresh sperm, Boada noted.

“Radiation impairs the quality and viability of human sperm, and these effects are expected to be greater on fresh sperm than on frozen samples,” she said.
