The "Science and Space" Thread #2
Big Bang Conditions Created in Lab.
By smashing gold particles together at super-fast speeds, physicists have basically melted protons, creating a kind of "quark soup" of matter that is about 250,000 times hotter than the center of the sun and similar to conditions just after the birth of the universe.

"Runaway" supermassive black hole creates new stars in its wake
Astronomers have spotted a bizarre sight out in the cosmos unlike anything they’ve ever seen before. A supermassive black hole has been ejected from its host galaxy, leaving a streak of light almost twice as wide as the Milky Way in its wake as the shockwaves create new stars.
Explaining JUICE: Mission to Jupiter and its moons
The Jupiter Icy Moons Explorer (JUICE) has lifted off from French Guiana to begin its eight-year journey to Jupiter and its icy moons, which scientists think could support living organisms.
With SpaceX confirming Starship is now ready for flight, all eyes were on the Federal Aviation Administration (FAA) to issue its launch license. That was finally granted on Friday evening (April 14).
Before the FRR, a preliminary plan called for a Wet Dress Rehearsal (WDR) to be performed on April 11. However, as part of the decisions taken during the meeting, SpaceX decided to forego this test and proceed directly with a launch. This option would give the teams time to close out issues while still keeping the opportunity to launch on April 17.
Starship ready for historic maiden flight, gains FAA launch licenseAmended road closure: Boca Chica Beach will now be closed on April 17 for spaceflight activities! Backup dates on April 18 and 19.

Update: Monday April 17, 2023
Fuel and oxidizer loading underway. Targeting a launch at 8:20am CDT (13:20 UTC)
Update: Monday April 17, 2023 8:25am
Because of a frozen valve the launch attempt has been scrubbed. The launch will be attempted again at a later TBD.
Currently the current attempt is going to be considered a wet dress rehearsal.

Earth-like exoplanets may be much more common than previously thought
A new study led by UCLA scientists on how water forms on young exoplanets with hydrogen atmospheres and molten oceans of magma suggests that Earth-like planets may not be as uncommon as once thought and that the presence of water on such planets may be almost inevitable.
Upcoming Starship Flight TestSpaceX is targeting as soon as Thursday, April 20 for the first flight test of a fully integrated Starship and Super Heavy rocket from Starbase in Texas. The 62 minute launch window opens at 8:28 a.m. CT and closes at 9:30 a.m. CT.
NASA Shares First Moon to Mars Architecture Concept Review Results
“Our first Architecture Concept Review is a milestone that will help our Moon to Mars strategy unfold through the objectives in missions both near and long term,” said NASA Deputy Administrator Pam Melroy. “We’re aligned with partners toward a future of expanded economic opportunity, scientific discovery, and greater activity on and around the Moon, and with limitless possibilities deeper in the solar system.”
Goodbye, Rock Friend! Mars rover loses pet rock
The pair had traveled about 6.2 miles (10 km) across the surface of Mars during a period of 427 sols (439 Earth-days, or more than an earthly year). Space scientists had dubbed it Rock Friend, as they followed along from Earth, after it hitched a ride in the rover’s front left wheel.
People enjoyed watching the rock. Now it’s gone.
New space habitat from Airbus looks sci-fi slick
While the space capsules allocated to astronauts look sleek, spacious and comfy in science fiction films, the reality for those living on the International Space Station (ISS) is a little different. If you've ever seen photos of the quarters on the ISS, you know they tend to look a little cramped and crowded with, well, stuff. Airbus is aiming to change this up with a new design called the Loop, that could merge the design of Hollywood with the practical needs of those living in space for extended periods of time.
Lockheed Martin demonstrates system for servicing CubeSat swarms
In an autonomous orbital ballet, Lockheed Martin's In-space Upgrade Satellite System (LM LINUSS) completed a demonstration of how highly automated CubeSats can upgrade and service increasingly common constellations of small satellites.
This strange blue asteroid has another big surprise for us
This was already a strange occurrence, since comets have tails, due to their icy make-up, not rock-and-metal asteroids. It’s long been thought to be dust that had been expelled from the asteroid’s surface.
Now, scientists have discovered that there’s no dust in sight; it is, in fact, an impressive tail made up of sodium gas.
NASA’s Voyager Will Do More Science With New Power Strategy
The plan will keep Voyager 2’s science instruments turned on a few years longer than previously anticipated, enabling yet more revelations from interstellar space.
Brit fusion magnets set for US gamma ray bombardment test
The Oxford-based company has developed magnet technology it hopes will be able to withstand the electromagnetic bombardment from a fusion reaction while being capable of holding reaction in place.
Nuclear fusion relies on combining lighter chemical elements into heavier ones, releasing unprecedented weight-for-weight energy compared with fission and chemical reactions. During the process, engineers need to hold hydrogen fuel in place with powerful magnets. If the process is ever to be industrialized, these magnets must also be resistant to the powerful gamma rays fusion reactions emit.
Key radar antenna stuck on Europe’s Jupiter-bound spacecraft
The radar antenna is needed to peer beneath the icy crust of three Jupiter moons suspected of harboring underground oceans and possibly life, a major goal of the nearly $1.8 billion mission. Its targets include Callisto, Europa and Ganymede, the largest moon in the solar system.
Mutual destruction: Binary stars, black holes, and ripples in space-time
The stars, which orbit around a shared center of gravity and together are known as a binary star, are in the Small Magellanic Cloud, a mere 210,000 light-years away from our Milky Way galaxy. The stars orbit one another every three days and are the biggest touching stars (contact binaries) ever observed. But it’s their mutually destructive relationship that piqued the interest of the researchers.
NDAs help Elon Musk's exploding rocket problem stay in the dark
When SpaceX's rocket Starship blew up shortly after take-off last week, questions rose about safety, intentions, and consequences. While company PR posed the vehicle's "rapid unscheduled disassembly" as immaterial to the technical success of the test launch before it, residents had already expressed their disagreement with the launch and its possible environmental impact.
China's Mars rover finds signs of recent water in sand dunes
Water may be more widespread and recent on Mars than previously thought, based on observations of Martian sand dunes by China's rover.
The finding highlights new, potentially fertile areas in the warmer regions of Mars where conditions might be suitable for life to exist, though more study is needed.
