Many Astronauts Never Recover all of their Bone Density after Returning to Earth

In his book, Endurance, astronaut Scott Kelly described the arduous task of readjusting to life on Earth after spending a year in space. As part of NASA’s Twins Study, Kelly lived and worked aboard the International Space Station (ISS) while his identical twin (astronaut Mark Kelly) remained on Earth. While the results of this study revealed how prolonged exposure to microgravity could lead to all manner of physiological changes, the long and painful recovery Kelly described in his book painted a much more personal and candid picture.

As it turns out, astronauts who spend extended periods in space may never fully recover. At least, that is the conclusion reached by an international team led by the University of Calgary after they assessed the bone strength of multiple astronauts before and after they went to space. They found that after twelve months of recovery, the astronaut’s bones had not regenerated completely. These findings could have significant implications for proposed future missions, many of which involve long-duration stays in space, on the Moon, and Mars.

This is reminiscent of going down slide on the playground – and then immediately getting back in line to go down again. Except in space.

Here’s what it looks like on board the International Space Station when thrusters fire for an orbital reboost. While it seems like the astronauts are moving inside the station, in in reality it is the Space Station that is moving around them. And in actuality, the acceleration doesn’t happen this fast – the video is sped up eight times. But it still looks like fun!

Axiom Space’s first crew of private astronauts is back on Earth after a 17-day orbital trip that included a week of bonus time on the International Space Station. The mission ended at 1:06 p.m. ET (5:06 p.m. GMT) today when SpaceX’s Crew Dragon Endeavour splashed down in the Atlantic Ocean off the coast of Florida.

Former NASA astronaut Michael Lopez-Alegria was the commander for the homeward trip, accompanied by three investors who each paid Axiom $55 million for their rides: Ohio real-estate and tech entrepreneur Larry Connor, who served as the mission pilot, plus Canada’s Mark Pathy and Israel’s Eytan Stibbe.

“Welcome back to planet Earth,” SpaceX’s mission control operator Sarah Gillis told the crew. “The Axiom-1 mission marks the beginning of a new paradigm for human spaceflight. We hope you enjoyed the extra few days in space.”

Axiom-1 began on April 8 with the Florida launch of a SpaceX Falcon 9 rocket. The trip was originally supposed to last about 10 days, but concerns about weather in the splashdown zone delayed the descent. Because of the way their fares were structured, Axiom’s customers didn’t have to pay extra for the extension.

This morning, at 11:17 AM EDT (08:17 AM PDT), the first all-private astronaut mission to the International Space Station (ISS) lifted off from Launch Complex 39A at NASA Kennedy Space Center in Florida. Designated Axiom Mission 1 (Ax-1), this mission consists of four commercial astronauts flying aboard the SpaceX Dragon Endeavour spacecraft that launched atop a SpaceX Falcon 9 rocket. The launch was live-streamed via NASA’s official Youtube channel (you can catch the replay here).

Three Cosmonauts Arrive at the ISS Wearing Bright Yellow Jumpsuits

About a month ago, Russian forces invaded Ukraine, placing NATO on high alert and creating a shock wave felt around the world. One place that has been particularly resilient to the effects of this conflict is the International Space Station (ISS). Even as tensions mount and the heads of space agencies engage in an online war of words, astronauts and cosmonauts continue to work and live together in orbit.

On the other hand, there have been some clear attempts to drag the ISS into political turmoil. Case in point: the recent photo that shows three Russian cosmonauts wearing bright yellow and blue jumpsuits, the colors of the Ukrainian flag! Depending on who you ask, this was either a display of unity with the people of Ukraine or just a coincidence. Opinions vary, but this was likely nothing more than oddly fortuitous.

Wondering how Dependant ISS is on Russia? NASA Gives the Details

The Russian invasion of Ukraine has been dominating the news cycle lately. Amid tragic stories about rocket strikes, stalled offensives, and possible motives and outcomes, there’s been an ongoing “war of words” on social media. In particular, Dmitry Rogozin, the Director-General of the Russian State Space Corporation (Roscosmos), has been issuing thinly-veiled threats that Russia might be terminating its cooperation in space.

This included a video posted on Telegram by the state-controlled Russian news agency RIA Novosti that shows the Russian modules detaching from the International Space Station (ISS). In response to all the threats and hyperbole, NASA decided to host an FAQ session where they posted commonly-asked questions about the ISS. In what is eerily reminiscent of what happened in 2014, NASA let the world know that the ISS is still going strong and won’t be decommissioned anytime soon!

Russian Space Agency Tweets a Bizarre Video Showing the Russian Modules Detaching From ISS

The world is on high alert because of the unfolding crisis between Ukraine and Russia. Ever since Russian troops began deploying to the border regions between the two countries, there have been fears that conflict would ensue. Since the invasion began, there have also been genuine anxieties that it could spill over into neighboring states and even escalate to the point of a nuclear standoff. In the midst of all this, there have also been worries about the toll it might take on international efforts in space.

The International Space Station (ISS) is made possible through the cooperative efforts and funding of its participating space agencies – NASA (U.S.), Roscosmos (Russia), the ESA (Europe), the CSA (Canada), and JAXA (Japan). As such, it was rather curious when Russian state media company RIA Novosti posted a video online that showed Russian cosmonauts packing up and detaching the Russian segment from the ISS. Whether this represents a threat or a prediction, the message is clear: cooperation in space may be the next casualty of this war!

NASA Details Its Plan for the End of the International Space Station in 2031

NASA says it plans to plunge the vestiges of the International Space Station into a remote part of the Pacific Ocean known as Point Nemo in early 2031, after passing the baton to commercial space stations.

In an updated transition report just delivered to Congress, the space agency detailed the endgame for the space station, which has been hosting international crews continuously since the year 2000 — and hinted at what its astronauts would be doing in low Earth orbit after its fiery destruction.

“The private sector is technically and financially capable of developing and operating commercial low-Earth-orbit destinations, with NASA’s assistance,” Phil McAlister, NASA’s director of commercial space, said in a news release. “We look forward to sharing our lessons learned and operations experience with the private sector to help them develop safe, reliable, and cost-effective destinations in space.”

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.”

Fungi Were Able to Absorb Radiation on the ISS. Could Astronauts Grow Their own Radiation Shields in Space?

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.
