For reasons by Vivaldi

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,

Wildfire Map wins top prize at App Camp

An app that uses satellite data to show the location and impact of wildfires took home the top prize at this year’s Space App Camp.
Orbit Fab to launch propellant tanker to fuel satellites in geostationary orbit

Orbit Fab, a startup offering a refueling service in space, will launch a propellant tanker to geostationary orbit on a SpaceX Falcon 9 lunar lander mission projected for late 2022 or early 2023.
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

UN secretary-general criticizes “billionaires joyriding to space”

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.
Op-ed | Can we backhaul our way to space?

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.
Blue Origin, Rocket Lab, SpaceX, ULA win Space Force contracts for rocket technology projects

Blue Origin, Rocket Lab, SpaceX and United Launch Alliance were selected to participate in Space Force development projects to advance rocket engine testing and launch vehicle upper stages.
Going hyperspectral for CHIME

With Covid restrictions a little more relaxed, scientists from Europe and the USA were finally able to team up for a long-awaited field experiment to ensure that a new Copernicus satellite called CHIME will deliver the best possible data products as soon as it is operational in orbit. This new mission is being developed to support EU policies on the management of natural resources, ultimately helping to address the global issue of food security.
