Humanity has big dreams when it comes to space travel, but our technology isn’t quite there yet. Spacecraft that can take astronauts to Mars and beyond are already in development but some huge questions remain, and one of the biggest issues is food.

Simply packing enough food to last for the entirety of the trip would be terribly inefficient and would leave space travelers in a tight spot if their return is delayed and they somehow run out of things to eat. Growing traditional foods onboard is also a tough sell due to the length of time it would take to grow and harvest it. Now, researchers from Penn State have come up with a novel alternative, and it starts with something astronauts will have no shortage of: poop.

A first look at the out-of-this-world fashion.

Spent rockets are dangerous space trash, but they could be the future of living and working in orbit.

Recent advances indicate that the idea could work.

This test is a routine pre-flight preparation meant to assess the three Raptor engines and all systems related to the propulsion system before a launch vehicle takes flight. SN8 is expected to become the first fully-assembled Starship prototype to perform a test flight. Engineers plan to launch Starship SN8 50,000 feet (15-kilometers) into Boca Chica Beach, Texas, sunny sky. Tuesday’s static-fire test was the second one performed. Raptor engines are fueled by a combination of cryogenic methane and liquid oxygen. During the test, engineers fuel the vehicke to briefly ignite the Raptors as the stainless-steel Starship SN8 vehicle remained grounded to a test stand at the South Texas Launch Facility. Last night’s engine ignition was different than the previous one; This time, SN8 featured a top nose cone section with an oxygen header tank. The vehicle’s first static-firing only featured the bottom base and excluded a test of the header propellant tanks. On October 20, teams performed the first static-firing in which the Starship SN8’s three Raptor engines where briefly ignited for the first time, utilizing fuel from the main propellant tank. Starship features two propellant tanks — a main one that holds most of the propellant and a ‘header tank’ that is a smaller tank that holds fuel reserves that can fuel the vehicle upon landing. A header tank for liquid oxygen is also located inside the vehicle’s top nose cone section.

Admitting he was both nervous and excited about the upcoming launch aboard the Crew Dragon capsule on a SpaceX Falcon 9 rocket, the 55-year-old said, “There are risks and a fear of failure when challenging oneself but I believe the benefits far outweigh that fear.”

Noguchi will be among four astronauts, including crew commander Michael Hopkins, aboard the Crew Dragon capsule to be launched from Kennedy Space Center in Florida on Saturday.

He juxtaposed the mission to the Japanese hit manga and anime series “Demon Slayer,” in which astronauts use and maximize their “individual strengths” toward a “common goal.” The series follows the story of a boy who, along with his comrades, fights human-eating demons after his family is killed by them.

It’s twice as efficient as a chemical rocket.

Ultra Safe Nuclear Corporation (USNC) has designed a new thermal nuclear engine it says could carry astronauts to Mars in just three months—and back to Earth in the same amount of time. By using ceramic microcapsules of high assay low enriched uranium (HALEU) fuel, USNC’s thermal nuclear engine could cut the trip in half even from optimistic estimates.

WASHINGTON — NASA formally certified SpaceX’s Crew Dragon spacecraft for transporting astronauts to and from the International Space Station, clearing the way for a Nov. 14 launch.

Agency officials completed the certification of the spacecraft by signing a document known as a Human Rating Certification Plan during a flight readiness review for the Crew-1 mission Nov. 10. That confirmed that SpaceX met all of NASA’s requirements for safely carrying astronauts on the Crew Dragon spacecraft and Falcon 9 launch vehicle.

“It’s just a tremendous day that is a culmination of a ton of work,” said Kathy Lueders, NASA associate administrator for human exploration and operations, at a Nov. 10 briefing about the flight readiness review. Lueders managed the commercial crew program at NASA for several years before being promoted to her current position in June. “It’s NASA saying to SpaceX you have shown us you can deliver a crew transportation capability that meets our requirements.”

A Chinese team has demonstrated a prototype of a microwave plasma thruster capable of working in the Earth’s atmosphere and producing thrust with an efficiency comparable to the jet engines you’d find on modern airliners – under laboratory conditions.

Plasma thrusters are already operational on spacecraft as a means of solar-electric locomotion, using xenon plasma, but such things are no use in the Earth’s atmosphere, as accelerated xenon ions lose most of their thrust force to friction against the air. Not to mention, they only make a small amount of thrust in the first place.
