SEOUL, South Korea — In response to the reignited global space race, Japan is planning a record space budget of 449.6 billion yen ($4.14 billion) in the fiscal year 2021, up 23.1 percent over the current fiscal year that ends March 30, according to draft budget documents.
Early Mars climate was intermittently warm
Monday, 08 March 2021 12:47 Write a comment
A new study that characterizes the climate of Mars over the planet's lifetime reveals that in its earliest history it was periodically warmed due to the input of greenhouse gases derived from volcanism and meteorites, yet remained relatively cold in the intervening periods, thus providing opportunities and challenges for any microbial life form that may have been emerging on the Red Planet. The study involved a national team of scientists that included Joel Hurowitz, Ph.D., of Stony Brook University. The findings are detailed in a paper published in Nature Geoscience.
An astronaut's guide to out-of-Earth manufacturing
Monday, 08 March 2021 12:45 Write a comment
mprovising new stuff from the stuff you have is part of an astronaut's job description—think Apollo 13's crew refitting CO2 filters to save their own lives, or stranded Mark Watney in The Martian, feeding himself on the Red Planet. Now plans are underway to manufacture items in orbit, and ESA astronaut Alexander Gerst argues this could make a big difference to living and working in space.
Alexander—who has spent just under a year in orbit, becoming the second European to command the International Space Station (ISS) – spoke at ESA's Workshop on Advanced Manufacturing, which included a special session on out-of-Earth manufacturing.
While plastic-producing 3D printers have already reached space, the virtual event heard how ESA will fly the first metal 3D printer in 2022, and researchers are also planning large-scale manufacturing such as spacecraft printing their own antennas or solar arrays after launch.

Research contributes to understanding of hypersonic flow

Using data collected in a NASA Langley Mach 6 wind tunnel, researchers at the University of Illinois Urbana-Champaign replicated the hypersonic flow conditions of a compression ramp flow by means of Direct Numerical Simulation. The simulation yielded an abundance of additional data, which can be used to better understand the phenomena that occur surrounding vehicles traveling at hypersonic speed Moving into Cislunar Space

The space community is moving beyond Low-Earth Orbit (LEO) and expanding more activities toward the Moon and in cislunar space, i. e., lying between the earth and the moon or the moon's orbit. Thus, as in LEO, space is getting more congested with crowding and pollution problems. As countries expand commercial and military cislunar operations we can expect to face the challenges of managing space China's Chang'e 4 lander and rover resume work for 28th lunar day

The lander and rover of China's Chang'e 4 probe have begun their 28th lunar day of work on the far side of the moon.
Landing on the moon on Jan. 3, 2019, the Chang'e 4 probe has survived 795 Earth days on the moon, the Lunar Exploration and Space Program Center of the China National Space Administration said Monday.

When a block of ice the size of Houston, Texas, broke off from East Antarctica's Amery Ice Shelf in 2019, scientists had anticipated the calving event, but not exactly where it would happen. Now, satellite data can help scientists measure the depth and shape of ice shelf fractures to better predict when and where calving events will occur, according to researchers.
Ice shelves make up near Nuclear fusion: building a star on Earth is hard, which is why we need better materials
Monday, 08 March 2021 09:54 Write a comment
Nuclear fusion is the process that powers the Sun and all other stars. During fusion, the nuclei of two atoms are brought close enough together that they fuse together, releasing huge amounts of energy.
Replicating this process on Earth has the potential to deliver almost limitless electricity with virtually zero carbon emissions and greater safety, and without the same level of nuclear wa China rolls out out new Long March 7A for second launch attempt

When spring arrives in southern Mars, a cloud of water ice emerges near the 20-kilometre-tall Arsia Mons volcano, rapidly stretching out for many hundreds of kilometres before fading away in mere hours. A detailed long-term study now reveals the secrets of this elongated cloud, using exciting new observations from the ‘Mars Webcam’ on ESA’s Mars Express.
