Japanese billionaire Yusaku Maezawa and two crewmates have returned to Earth after an 11-day mission to the International Space Station that was marked by online innovations including an NFT drop and a lottery giveaway.
Maezawa, his production assistant Yozo Hirano, and Russian cosmonaut Alexander Misurkin took a 3.5-hour ride from the station on a Soyuz craft, climaxing in a touchdown amid the steppes of Kazakhstan around the appointed time of 0313 GMT (9:13 a.m. local time) Dec. 20.
After the landing, the three spacefliers were helped out of the capsule and given medical checks.
The short-duration stay was the first private astronaut trip to the space station brokered by Virginia-based Space Adventures in 12 years. In an interview with The Associated Press, Maezawa said reports that he paid more than $80 million for the adventure were “pretty much” accurate.
“Once you are in space, you realize how much it is worth it by having this amazing experience,” he told AP. “And I believe that this amazing experience will lead to something else.”

A lack of effective radiation shielding is one of the biggest challenges still to be overcome if humans are to embark on long-term voyages into deep space. On Earth, the planet’s powerful magnetosphere protects us from the deadliest forms of radiation – those produced by solar flares, and galactic cosmic rays arriving from afar – that stream through the Solar System. Astronauts on the International Space Station, some 408km above the Earth, receive elevated levels of radiation, but are close enough to Earth that they still receive some shielding, and can stay on orbit for up to a year. The same can’t be said for astronauts traveling further out, to the Moon, for example, or, someday, to Mars. Future deep space voyagers will need to bring their own shielding with them – or, as a new paper suggests – grow it along the way.

Blue Origin has certainly stepped up its game of late! After stepping down as the CEO of Amazon, Jeff Bezos has made it his personal mission to take the company he founded in 2000 and turn it into a powerhouse of the commercial space sector. Between some high-profile missions involving the New Shepard – which included passengers like Wally Funk, William Shatner, and even himself and his brother – Bezos has also been outspoken about his long-term vision.
Bezos describes this vision as “building a road to space so our children can build the future.” In the latest step towards achieving this, Blue Origin announced a new partnership with Sierra Space to develop a commercial space station in Low Earth Orbit (LEO), known as “Orbital Reef.” This mixed-use space station, which is to be completed by the end of this decade, will facilitate commerce, research, tourism, and facilitate the commercialization of LEO.

In 2011, NASA announced a bold new program to leverage partnerships between the government and the commercial space sector to restore domestic launch capability. As part of the Commercial Crew Program (CCP), NASA selected Boeing and SpaceX to develop next-generation crew-rated capsules that would transport astronauts and payloads to International Space Station (ISS) and other locations in Low-Earth Orbit (LEO).
While SpaceX has managed to meet all the requirements of the CCP with their Crew Dragon module, Boeing’s Starliner has experienced technical problems and several delays. With the latest delay (caused by the ISS being temporarily pushed out of its orbit), NASA has decided to reassign the astronauts that were scheduled to take the Starliner on its maiden crewed flight (Starliner-1) to the next crewed flight of the SpaceX Crew Dragon to the ISS (Crew-5).

On July 28th, the International Space Station (ISS) suffered a mishap after a new Russian module (named Nauka) fired its thrusters just hours after arriving. As a result, the entire station was temporarily pushed out of position, forcibly delaying the Orbital Flight Test-2 (OFT-2) mission. This would have been Boeing’s CT-100 Starliner’s second attempt to rendezvous with the ISS as part of NASA’s Commercial Crew Program (CCP).
The ISS managed to correct its orbit shortly thereafter, while the OFT-2 launch was delayed until the next available opportunity (Wednesday, Aug. 4th). Unfortunately, the mission was delayed again due to an issue with one of the valves on the spacecraft’s propulsion system. This prompted the ground crews to move the Starliner and Atlas V launch vehicle back into Vertical Integration Facility (VIF), so they can look for the source of the problem more closely.

It’s not easy living and working in space for extended periods of time. As NASA’s Twins Study illustrated, microgravity takes a toll on human physiology, which is followed by a painful transition back to normal gravity (just ask Scott Kelly!) Aside from muscle and bone degeneration, there’s diminished organ function, effects on cardiovascular health, the central nervous system, and “subtle changes” on the genetic level.
Until now, the biggest unanswered question was what the underlying cause of these physical impacts was. But after reviewing all of the data accumulated from decades of research aboard the International Space Station (ISS) – which included the Twins Study and DNA samples taken from dozens of astronauts – an international team of researchers came to the conclusion that mitochondria might be the driving force for these changes.

Earlier this evening (Sunday, November 15th, 2020), NASA and SpaceX achieved another historical milestone. Six months after successfully sending astronauts Robert Behnken and Douglas Hurley to the ISS with the Demo-2 mission, the US demonstrated the restoration of domestic launch capability by sending the fully-crewed Crew Dragon spacecraft (Resilience) on an operational mission to the ISS.

On the evening of Wednesday, Oct. 21st, the crew of Expedition 63 finally returned to Earth after spending 196 days in space. It all began when NASA astronaut Chris Cassidy (commander) and Russian cosmonauts Ivan Vagner and Anatoly Ivanishin (both flight engineers) departed the International Space Station (ISS) aboard their Soyuz spacecraft at 07:32 PM EDT (04:32 PM PDT) and landed in Kazakhstan by 10:54 PM EDT (07:54 PM PDT).

When human beings start living in space for extended periods of time they will need to be as self-sufficient as possible. The same holds true for settlements built on the Moon, on Mars, and other bodies in the Solar System. To avoid being entirely dependent on resupply missions from Earth (which is costly and time-consuming) the inhabitants will need to harvest resources locally – aka. In-Situ Resource Utilization (ISRU).
This means they’ll have to procure their own sources of water, building materials, and grow their own food. While the ISS has allowed for all kinds of experiments involving hydroponics in space, little has been done to see how soil fares in microgravity (or lower gravity). To address this, Morgan Irons – Chief Science Officer of the Virginia-based startup Deep Space Ecology (DSE) – recently sent her Soil Health in Space experiment to the ISS.

On Tuesday, Sept. 29th, the Russian State Space Corporation (Roscosmos) announced that astronauts aboard the International Space Station (ISS) had found the source of a suspected leak. The crew of Expedition 63 – NASA astronaut and Commander Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner – had been searching for this leak since August, and determined that it was “beyond expected levels.”
Roscosmos also said in a statement that “it was established that the spot is located in the Zvezda (star) service module, which contains scientific equipment.” They also emphasized that the leak “is not dangerous for the life and health of the ISS crew and does not prevent the ISS continuing manned flight.” Nevertheless, the amount of atmosphere lost may require additional oxygen to be pumped into the station.
