Don't worry, that's not an astronaut lost in space, it's just an empty spacesuit. The suit was a decommissioned Russian spacesuit. It was dubbed Suitsat-1 and was pushed into orbit by the crew of the ISS in 2006. The suit orbited Earth for a few months before burning up in reentry. #Astronomy ⚛️🧪🛰️

To think of it another way, the hardware cost SpaceX $100 million. They're willing to spend that to collect the test flight data. In the end, it's up to them how much the data is worth. Seeing as they planned for this flight to end in this way, they must see it as a worthwhile investment. (3/3)

The best way to be able to ensure future safe landings is to gather as much data as possible from test flights, regardless if they end in a safe or destructive landing. If Starship had attempted a safe landing and exploded, that would be a failure (but still a failure they could learn from). (2/3)

When it comes to rockets, there's really only two ways to land. A safe landing or a destructive landing. If you can't ensure a safe landing, then it's far safer overall to plan for a destructive landing in place where it can't harm people, such as the middle of the ocean. (1/3)

The goal was to make it to orbit, and they did. That's a success. The explosion can't be counted against it, because they planned it from the start. The real point of these missions is data gathering. With what they learned here, they can improve the next version. Cracking eggs to make omelets.

I probably should have said "first rocket designed to be reused to make it to orbit" instead. Everything about Starship is reusable in theory, but they're still too early in the testing phase to confidently and safely land it for reuse, so they planned for this destructive water landing instead.

The proof of concept for reaching orbit was the key here. I should have said "first rocket designed for reuse in orbit" instead. To answer your actual question, SpaceX has reused heat shield tiles before, so maybe some of those will be salvaged for reuse. Otherwise, likely not. (2/2)

They actually intended for this launch to not be reused. Both the booster and upper stage were planned to land with a splashdown, rather than the reusable landing as they're still early in the testing phases and couldn't ensure a safe landing. (1/2)

Gamma-ray burst are incredibly rare, with a single galaxy only experiencing a few every million years. We have yet to record one in the Milky Way.

Gamma-ray bursts are believed to occur during the supernovae of extremely massive stars as they collapse into neutron stars or black holes. Jets of gamma rays are launched from the poles. One pointed at Earth in our galaxy, even at the opposite end, would cause a mass extinction. (2/3) 🔭⚛️🧪🛰️

Cloud Gazing - What is a Nebula?
Nebulae are among the most visually stunning sights in our universe. A nebula is simply a cloud of gas and dust found in outer space, and their varied shapes and colors make them spectacular phenomena for night sky viewing. They also play important roles in the life cycle of stars, as both a place of birth and a place of death.

Our model of physics is not complete, and it would be premature to rule out a warp drive. Nothing says its impossible. I admit I'm out of my league on this, as I'm not a theoretical physicist, but what I know is that there are many credible, peer reviewed studies exploring the possibility. (3/3)

We may not know if negative energy can exist in large scales or not, but the fact that it can exist at all suggests it's a possibility. As for causality, that really comes down to needing to question how accurate our understanding of the universe is. We don't have a unified theory yet. (2/3)

While Alcubierre's original paper did require astronomical amounts of energy, newer papers have lowered that amount significantly towards the planetary mass scale. As for negative energy, we actually do know it exists on microscopic scales via the Casimir effect. (1/3)

It's all good if you don't want to read the article. But while it does sound like pure sci-fi, it's actually a serious scientific topic. A real warp drive has been suggested by respected physicists. It's far in the future and not guaranteed to work, but for now, the physics suggests it's possible.

Galaxies tend to have a black hole at their center. If the black hole has an accretion disk, an orbiting ring of material, the accreting gas and dust is moving so fast that there's a lot of friction, and friction creates heat and light. This is what causes AGN to glow intensely. (2/3) 🔭⚛️🧪🛰️

Mars is different because its thin atmosphere is permeated with dust grains. As these grains are larger than air molecules, they primarily scatter a different wavelength of light; red instead of blue. This means that the Martian atmosphere has the opposite effect on light. (3/3) 🔭⚛️🧪🛰️

Earth's blue sky is due to gas molecules in our atmosphere that scatter blue light in all directions more so than other colors. But at sunset light has to travel at a steeper angle, and therefore through more air, meaning all the blue light has been scattered away before reaching you. (2/3) 🔭⚛️🧪🛰️
