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 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 How would rain be different on an alien world?
On Titan, Saturn's largest moon, it rains on a regular basis. As with Earth, these rains are the result of liquid evaporating on the surface, condensing in the skies, and falling back to the surface as precipitation. On Earth, this is known as the hydrological (or water) cycle, which is an indispensable part of our climate. In Titan's case, the same steps are all there, but it is methane that is being exchanged and not water.
In recent years, scientists have found evidence of similar patterns involving exoplanets, with everything from molten metal to lava rain! This raises the question of just how exotic the rains may be on alien worlds.
ESA and Mattel help to close the ‘Dream Gap’
ESA and international toy manufacturer Mattel are taking further steps to raise awareness of the importance of female role models during times of pandemic and beyond.
USTC detects a sharp rise in detection rate of broad absorption line variations
Gas around black holes and interstellar medium distribution are key factors in understanding the growth of supermassive black holes and the evolution of their host galaxies. However, as a crucial parameter, gas density is hard to be determined reliably, because the general method is not applicable to all quasars.
Researchers from the University of Science and Technology of China (USTC) of Will this solve the mystery of the expansion of the universe
The universe was created by a giant bang; the Big Bang 13.8 billion years ago, and then it started to expand. The expansion is ongoing: it is still being stretched out in all directions like a balloon being inflated.
Physicists agree on this much, but something is wrong. Measuring the expansion rate of the universe in different ways leads to different results.
So, is something wrong New 'Eyewear' to Deepen the View of NASA's Roman Space Telescope
NASA's Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening up exciting new opportunities for discoveries from the edge of our solar system to the farthest reaches of space.
"It's incredible that we can make such an impactful change to th Studying Near-Earth Asteroids with Radar
Some observatories - like the recently collapsed Arecibo Telescope in Puerto Rico - examine nearby objects by bouncing radio light off of them. A new study has now improved how we analyze these observations to learn about near-Earth asteroids.
There's plenty we can learn about the universe from passive radio astronomy, in which we observe the radio signals emitted by distant sources. But w Women making the Webb Space Telescope a reality
On the occasion of International Women’s Day 2021, and as excitement builds for the launch of the James Webb Space Telescope (Webb) in October, ESA is highlighting women that play an important role in Europe’s contribution to Webb.
An astronaut’s guide to out-of-Earth manufacturing
Improvising 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.
