Starship is threatening NASA’s moon contractors, which are watching its progress with a mix of awe and horror.

Right above you is the sky – or as scientists would call it, the atmosphere. It extends about 20 miles (32 kilometers) above the Earth. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe.
Above the atmosphere is space. It’s called that because it has far fewer molecules, with lots of empty space between them.
Have you ever wondered what it would be like to travel to outer space – and then keep going? What would you find? Scientists like me are able to explain a lot of what you’d see. But there are some things we don’t know yet, like whether space just goes on forever.
The ship could theoretically be used to start a city on Mars.
Musk reiterated that the specifications are still being finalized. As it stands, the booster measures 69 meters (226 feet) and the ship 50 meters (164 feet) to make a 119-meter (390-feet) tall construction. The ship itself has around 1,200 tons of propellant, and a thrust of around 1,500 tons. The diameter of nine meters or 30 feet will stay around the same.
The ship will send around 100 to 150 tons into space at a time, depending on the orbit. For orbital refilling, where a second Starship stays in space and refills a ship to complete the trip to Mars, Musk estimates the ship could carry 200 tons of payload.

Get ready for a giant update.
Elon Musk, CEO of SpaceX, is expected to provide an update on the current status of the company’s Starship project, the giant ship designed to send humans to Mars and beyond.
The ESA is investigating hibernation technology that could allow astronauts to remain healthy during long-duration missions to Mars and beyond.
A renewed era of space exploration is upon us, and many exciting missions will be headed to space in the coming years. These include crewed missions to the Moon and the creation of permanent bases there. Beyond the Earth-Moon system, there are multiple proposals for crewed missions to Mars and beyond. This presents significant challenges since a one-way transit to Mars can take six to nine months. Even with new propulsion technologies like nuclear rockets, it could still take more than three months to get to Mars.
In addition to the physical and mental stresses imposed on the astronauts by the duration and long-term exposure to microgravity and radiation, there are also the logistical challenges these types of missions will impose (i.e., massive spacecraft, lots of supplies, and significant expense). Looking for alternatives, the European Space Agency (ESA) is investigating hibernation technology that would allow their astronauts to sleep for much of the voyage and arrive at Mars ready to explore.
This researcher was the subject of a recent study led by Alexander Choukér, a professor of Medicine at the Hospital of the Ludwig-Maximilians-University (LMU), and Thu Jennifer Ngo-Anh – a payload coordinator with the ESA’s Directorate of Human and Robotic Exploration Programs. The paper that describes their findings was recently published in the journal Neuroscience & Biobehavioral Reviews.

Riding a laser to Mars
Posted in space travel
Could a laser send a spacecraft to Mars? That’s a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber behind the spacecraft, producing thrust from hydrogen gas and sending it to Mars in only 45 days. There, it would aerobrake in Mars’ atmosphere, shuttling supplies to human colonists or, someday perhaps, even humans themselves.
