Here's how Artemis 2 astronauts will exercise, sleep and use the toilet on their moon mission (photos)
NASA is getting the Artemis 2 Orion spacecraft built while testing key activities that astronauts will perform on their way to the moon and back.
Mercury was shrinking for at least 3 billion years — and it still might be today
New research indicates that Mercury's thermal contraction was still occurring as recently as 300 million years ago.
ESA and Axiom Space forge partnership for future space exploration
The European Space Agency ESA and Axiom Space signed a Memorandum of Understanding on 1 October in Paris to explore collaborative opportunities in human spaceflight, science, technology, and commercialisation.
Deep space missions will test astronauts' mental health. Could AI companions help?
Could AI companions provide mental health support for astronauts experiencing the most unique instances of social isolation ever experienced by human beings?
Shoebox-sized space labs being launched by Vega
Among the smallest passengers aboard Europe’s Vega launch tonight are also the most ambitious in nature: twin miniaturised laboratories, or CubeSats, for the in-orbit demonstration of disruptive state-of-the-art space technologies.
The ozone hole above Antarctica has grown to three times the size of Brazil
Observations from ESA's Copernicus Sentinel-5P satellite indicate the ozone hole above Antarctica is one of the largest seasonal holes ever observed.
Atlas V rocket launching Amazon's 1st internet satellites today: Watch it live
A United Launch Alliance Atlas V rocket will launch two prototype satellites for Amazon's Project Kuiper constellation today (Oct. 6), and you can watch it live.
Hypergravity odyssey of Earth’s tiniest plant
The smallest flowering plant on Earth might become a nutritious foodstuff for astronauts in the future, as well as a highly efficient source of oxygen. To help test its suitability for space, floating clumps of watermeal – individually the size of pinheads – were subjected to 20 times normal Earth gravity aboard ESA’s Large Diameter Centrifuge by a team from Mahidol University in Thailand.
This Week's Sky at a Glance, October 6 – 15
A partial/annular eclipse of the Sun washes across the Americas on Wednesday the 14th. Four days before, the waning Moon and Venus pair up in early dawn with Regulus glimmering between them.

Open doors for the ESA-ESRIN Open Day
Video: 00:05:59
On Friday 29 September, the European Space Agency opened the doors of the ESA Centre for Earth Observation, ESRIN, to host the ESA Open Day in the framework of the European Researchers' Night. With a full program of presentations, interviews, interactive games, hands-on workshops and various activities, more than 1400 people, among adults and children, had the opportunity to deepen their knowledge of the activities and programs in which ESA is involved every day.
Earth from Space: Nueva Vizcaya, Philippines

Parker Makes its Closest and Fastest Solar Flyby
The Parker Solar Probe is the little engine that just keeps going and going by the Sun. On September 27th, it made its 17th close approach and skimmed just 7.26 million kilometers (4.51 million miles) above the sun’s “surface” layer (called the photosphere).
Those Impossibly Massive Early Galaxies Might Just Be Surprisingly Bright
On July 12th, 2022, in an event live-streamed from the NASA Goddard Spaceflight Center, the James Webb Space Telescope’s (JWST) first images were released! Among them was the most detailed image of SMACS 0723, showing galaxy clusters and the gravitational lenses they produced. These lenses allowed astronomers to see deeper into the cosmos and spot galaxies as they appeared less than one billion years after the Big Bang (ca. 13 billion years ago). Upon further examination, however, they noticed something rather surprising about these early galaxies: they were much larger than expected!
Watch the trailer for surreal space exploration survival game 'The Alters' (video)
Polish gaming studio 11 Bit shared a new character reveal trailer for their upcoming space exploration survival game "The Alters."
Can JWST Tell the Difference Between an Exo-Earth and an Exo-Venus?
As of this month, astronomers have discovered 5,506 exoplanets orbiting other stars. That number is growing daily, and astronomers are hoping, among other things, to find Earth-like worlds. But will we know one when we see it? How might we be able to tell an Earth-like garden from a Venus-like pressure cooker from upwards of 40 light years away? Is JWST up to the challenge?
Europa and Enceladus are the Perfect Targets for a Lightsail Mission
There’s always a need for new technologies or for novel uses of existing technologies to lower the cost of space exploration and extend our reach. Lightsails are a novel type of spacecraft that could eventually be our first visitors to nearby stars like the Alpha Centauri system. But they could be put to productive use right here in our Solar System.
