SpaceX launch date of Crew-12 astronauts to the International Space Station will depend on the outcome of the Artemis 2 wet dress rehearsal and launch attempts.
We see stars as the main constituent of galaxies. They're the visible part, and they're what announce a galaxy's presence. But a galaxy's gas supply is its lifeblood, and tracing the gas as it flows in and through a galaxy reveals its inner workings.

Abnormally cold weather forecast over the weekend for Florida delayed both the earliest possible launch date for the Artemis 2 mission and a crucial fueling test for the Space Launch System rocket.
Blue Origin will ground its New Shepard suborbital vehicle for at least two years, in order to devote more resources to the company's crewed moon plans.
Ground-based observations suggest the former geostationary inspector satellite suffered a fragmentation event months after retirement, raising new concerns about debris in high Earth orbit.
Using the world's most powerful particle accelerator, the Large Hadron Collider, scientists have found that the quark-gluon plasma that filled the universe just after the Big Bang really was a primordial "soup."
Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.
Friday, Jan. 30, 2026: Follow NASA's last major test of SLS before the launch of Artemis 2 and a crew of astronauts around the moon.
Observations show that Jupiter's icy moon Europa has a thick icy shell covering a warm ocean. The ocean is chemically-rich, and may have all the essential ingredients for life. That's why Europa is such a juicy target in the search for life, and why NASA's Europa Clipper and the ESA's JUICE are on their way to examine the moon in greater detail.

The light, rare element boron, better known as the primary component of borax, a longtime household cleaner, was almost mined to exhaustion in parts of the old American West. But boron could arguably be an unsung hero in cosmic astrobiology, although it's still not listed as one of the key elements needed for the onset of life.
NASA has been forced to delay a critical fueling test for its Artemis 2 moon rocket due to unusually cold weather forecasted to hit the Space Coast this weekend.
When the rover now named Perseverance landed in Jezero crater in early 2021, scientists already knew they had picked an interesting place to scope out. From space, they could see what looked like a bathtub ring around the crater, indicating there could once have been water there. But there was some debate about what exactly that meant, and it’s taken almost five years to settle it. A new paper from PhD student Alex Jones at Imperial College London and his co-authors has definitively settled the debate on the source of that feature - part of it was once a beach.
The moon greets Jupiter two days ahead of its full moon phase on Feb. 1.
Both Windows and MacBooks have advantages for astrophotography, but the choice will depend on your power level and budget.
