As countries around the world respond to Russia’s invasion of Ukraine with sanctions aimed at crippling Moscow and Vladimir Putin, the global cooperation in space exploration that has been forged over the past 30-plus years will certainly be impacted.

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.”

70% of astronauts who spend time on the International Space Station (ISS) experience swelling at the back of their eyes, causing blurriness and impaired eyesight both in space and when they return to Earth. Sometimes, it’s permanent. Understanding the way microgravity affects the eyes, and the human body as a whole is an essential part of preparations for future long-duration spaceflights to the Moon and Mars. In an effort to understand the cause of these eye problems, researchers at the Medical University of South Carolina used MRI scans of twelve ISS astronauts to measure the intracranial venous system (veins that circulate blood to the brain) before and after flight. They’ve determined that there is a strong connection between the swelling of these veins and the onset of eye trouble.

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.”

Outer space is a great place to go if you want to study the Earth. Although outward-looking spacecraft like Hubble and the highly anticipated James Webb Space Telescope garner most of the attention from the public – understandably, given their spectacular imagery of distant astronomical phenomena – the large majority of satellite infrastructure in orbit is actually focused back on our home planet. The unparalleled view of the planet from space offers unique advantages to scientists hoping to measure changes and patterns here on Earth that just aren’t possible from the ground. In 2022, NASA will launch four new Earth science missions, each offering something unique, and adding a new way to understand, and protect, our home.
let’s take a look at the four missions, and what they hope to achieve in the coming years.

Even though Texas-based Axiom Space hasn’t yet sent its first crew of customers to the International Space Station, NASA is giving the company an opportunity to send a second crew, potentially just months later.
NASA says it will begin negotiations with Axiom on a space station mission scheduled sometime between the autumn of 2022 and the late spring of 2023. Under a pricing policy laid out earlier this year, NASA would charge $10 million to support each private astronaut during their stay in orbit, plus extra charges for food and supplies.
It’ll cost tens of millions more for the ride to the space station and back. The three customers who have signed up for Axiom’s first space station mission in February are reportedly paying $55 million each, which includes the fare for a trip in SpaceX’s Crew Dragon capsule.

Japanese billionaire Yusaku Maezawa has begun his first space adventure — an 11-day visit to the International Space Station that could serve as the warmup for a round-the-moon trip to come.
Maezawa, production assistant Yozo Hirano and Russian cosmonaut Alexander Misurkin rode a Soyuz capsule into orbit from Russia’s Baikonur Cosmodrome in Kazakhstan, with launch coming at 0738 GMT December 8 (12:38 p.m. local time, 2:38 a.m. EST).
Hours later, the Soyuz docked with the station, and the trio floated inside to meet the orbital outpost’s seven other spacefliers. Maezawa was all smiles as he greeted family and friends back on Earth over a video link.
Before liftoff, the 46-year-old entrepreneur and art collector said he was looking forward to his journey.
“I feel excited like an elementary student waiting for a school trip,” he said at a news conference. “I want to see the Earth from space, float in zero gravity, and see how I will change through this experience. I was blessed with this opportunity, and I’m truly happy I can go.”

While it may seem like the International Space Station is just now fully hitting its stride as far as scientific output and the ability for crew rotations from several different spacecraft, the ISS has been operating with astronauts on board for over 21 years. Knowing the modules and entire physical structure cannot endure the long-term effects of the harsh space environment forever, NASA’s Office of the Inspector General has issued a new report outlining the agency’s plans to keep the space station in orbit until 2030, and to replace it with one or more commercial space stations.

When astronauts left the International Space Station in early November to return home on the Crew Dragon Endeavour, they took the opportunity to do a fly-around of the ISS and take photos. NASA just released the new images, and they are a stunning look at both the orbiting outpost and our home planet.

Earlier this month, the Russian military conducted an anti-satellite (ASAT) missile test, launching a PL19 Nudol interceptor missile at a now-defunct Soviet-era intelligence satellite, KOSMOS 1408. The impact obliterated the spacecraft, creating a debris field consisting of approximately 1500 pieces of trackable debris, and potentially hundreds of thousands of pieces that are too small to monitor with ground-based radar. In the aftermath of the test, the debris field crossed the orbit of the International Space Station (ISS) repeatedly, causing the crew to take emergency precautions and shelter in their descent capsules, ready for a quick return to Earth in the event that the station was hit.
While the station and its crew escaped without harm this time around, the November 15 test demonstrated far too clearly that ASATs pose a real danger to human life. They can also wreak havoc on the rest of Earth’s space infrastructure, like communications satellites and other orbital systems. Debris from an ASAT test remains in orbit long after the initial incident is over (the higher the orbit, the longer lasting the debris), and if humanity’s space infrastructure is to be sustainable, the era of ASATs must come to an end, and soon.
