Timelapse video made during ESA astronaut Thomas Pesquet’s second mission to the International Space Station, “Alpha”. The camera is setup to take pictures at intervals of two a second, and the pictures are then edited into this video that plays at 25 pictures a second. The video is around 12 times faster than real speed.

Thomas shared this video on social media with the caption:

“A night #timelapse over South-East Asia. Green lights of squid fishing, bright city lights of Hong Kong and Shanghai followed by Seoul until the border of the Korean peninsula closes on a pitch black

If the market grows large enough, a dedicated lunar-to-LEO tanker industry could evolve – which might never happen if the infrastructure for supplying space facilities with lunar water had to be paid for up front and from scratch, before any water was delivered.

The secretary-general of the United Nations lumped space tourism alongside corruption and loss of freedoms as part of a “malady of mistrust” facing the world, another sign of the backlash in some quarters to private human spaceflight.

Exotic mix in China’s delivery of moon rocks

On 16 December 2020 the Chang'e-5 mission, China's first sample return mission to the Moon, successfully delivered to Earth nearly two kilograms of rocky fragments and dust from our celestial companion. Chang'e-5 landed on an area of the Moon not sampled by the NASA Apollo or the Soviet Luna missions nearly 50 years ago, and retrieved fragments of the youngest lunar rocks ever brought back for analysis in laboratories on Earth.

Scientists use seasons to find water for future Mars astronauts
Global map of Mars with overlaid topography indicating areas with significant seasonal variations in hydrogen content during northern spring (top) and fall (bottom). Green (red) represents increase (decrease) in hydrogen content. The areas highlighted in orange are Hellas Planitia in the southern hemisphere, and Utopia Rupes in the northern hemisphere. These are the only extended regions undergoing a significant variation throughout the Martian year.

A female volunteer gets comfortable in her waterbed, as the dry immersion study to recreate some of the effects of spaceflight on the body kicks off this week in Toulouse, France. Called Vivaldi, or Validation of the Dry Immersion, the campaign features all female-participants in a European first.

Immersion begins when water covers the subject above the thorax, immobilised with legs and trunk covered with a cotton sheet. Only the arms and head remain free outside the tarp.

As a result, the body experiences ‘supportlessness’ – something close to what astronauts feel while floating on the International Space Station.

In weightlessness,

Twenty-two years after putting the first African satellite into orbit, the continent's satellite fleet currently stands at 44. With Africa's most recent satellite launch taking place in June 2021, the next few years may see more launches on the continent. The consultancy Space in Africa recently reported that 44 satellites have been sent into orbit by 13 African countries since the launch

Engineering researchers have developed a method to use signals broadcast by Starlink internet service satellites to accurately locate a position here on Earth, much like GPS does. It is the first time the Starlink system has been harnessed by researchers outside SpaceX for navigation. The Starlink satellites, sent into orbit by Elon Musk's SpaceX, are designed to provide broadband internet

Forests, especially tropical rainforests, are guardians against climate change. But our forests are burning. They are withering and dwindling. Our guardians are themselves threatened by climate change. A new European Space Agency (ESA) satellite mission, currently being built by Airbus, is set to investigate exactly how our forests are faring. The name says it all: Biomass. Our forests and
