It is interesting that SpaceX has created working EVA suits for use later this year. Also cool that another crewed Starship mission has been planned. Finally note this is yet another mission without professional astronauts. (2 out of the 3 scheduled crewed Starship missions are with nonprofessionals.)
Jared Issacman would serve as the mission commander and will be accompanied by pilot Scott Poteet and SpaceX employees Sarah Gillis and Anna Menon.
The ISS is 1,000 times closer to us than the Moon, and 600,000 times closer than Mars. To get to the latter and back safely, we need faster rocket propulsion systems.
Using the conventional chemical rocket technology we have perfected at this time, a single mission to Mars will require the launch of a mass equal to 10 ISS to be put into space. It will involve at least 30 and as many as 40 of the largest rockets we have today to put the spacecraft, crew and fuel needed for the mission. That doesn’t include adding reserves of fuel placed strategically along the route should a problem arise going to Mars and coming back. Brown states that the total cost of a single mission using this approach would exceed $80 billion using the yet-to-be-launched SLS as the primary vehicle. With SpaceX and the Starship and Heavy booster, the cost could be cut by half. But even $40 billion for a single mission seems excessive.
Using nuclear-powered propulsion systems, however, would eliminate the need to put megatons of fuel into orbit. The only time chemical rockets would be used would be in launching the crew and spaceship components to Earth orbit. That could be done in as few as three launches with the final assembled ship going to Mars and back and then being parked in Earth orbit to be used again on future missions.
What additional advantages can be derived from using nuclear? Thermal-powered nuclear is at least twice as efficient as current chemical rockets and requires a tiny fraction of the fuel to get the job done. Electric-powered nuclear starts moving the rocket slowly away from Earth and then continuously accelerates to attain peak speeds of 200,000 kilometres (120,000 miles) per hour. An electric-powered nuclear propulsion system would use even less fuel than thermal-powered nuclear and would shorten the voyage to a month.
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.
