    One of SpaceX's greatest achievements is the development of reusable rockets. Before SpaceX, rockets were typically used only once, making space launches incredibly expensive. SpaceX's reusable rockets, such as the Falcon 9, have been able to land back on Earth after launch and be used again, significantly reducing the cost of space launches.

    Another major achievement of SpaceX is the launch of its Dragon spacecraft to the International Space Station (ISS). In 2012, Dragon became the first privately-developed spacecraft to successfully attach to the ISS and return cargo to Earth. This marked a major milestone in the privatization of space travel and opened up new possibilities for commercial activities in space.

    SpaceX also made history when it launched the first privately crewed spacecraft, the Crew Dragon, to the ISS in May 2020, with NASA astronauts on board. This marked the first time in history that NASA astronauts were launched into orbit from American soil on an American-made spacecraft.

    Lastly, another one of SpaceX's major accomplishments is the development of the Starlink satellite constellation. Starlink is a low Earth orbit satellite network that aims to provide global internet coverage. As of 2023, more than a thousand Starlink satellites are already in orbit, and SpaceX plans to launch many more in the coming years.

    In summary, SpaceX has achieved many milestones in the field of space technology, from reusable rockets to the privatization of space travel and global internet coverage via satellite.

    Tardigrades, also known as water bears, are tiny aquatic animals that are known for their incredible resilience and ability to survive in extreme environments.

    One of the most remarkable things about tardigrades is their ability to survive in a dehydrated state, known as cryptobiosis. They can go without water for extended periods of time and still come back to life once water is reintroduced.

    They are also incredibly resilient to radiation, extreme temperatures, and high pressures. They have been shown to survive temperatures as low as -328 degrees Fahrenheit and as high as 304 degrees Fahrenheit. They can also survive pressures up to 6 times greater than the pressure at the bottom of the ocean.

    Additionally, tardigrades have been found to survive in space and on the International Space Station, making them one of the few known organisms that can survive outside of Earth's atmosphere.

    Their resilience has led to the study of tardigrade's proteins, molecules and biochemistry in hopes of finding new ways to protect other organisms and even human cells from extreme environments.

    In terms of physical properties, air and water are both fluids. The key is to find a propulsion system that works in 'fluids' despite the external properties of the 'fluid' in question. I think it's very much possible. If not today, probably some time in the near future.

    Let's look at it positively. If (and this is a big IF), there was life on the planet, they would have 2.5 million years to find a survival solution. Look at what humanity has accomplished in the past say... 100 years. If we could accomplish that in 100 years, imagine what they could accomplish in 2.5 million years. They would most definitely have developed enough to the point of interstellar travel no matter how primitive the life might be there today.
