3D bioprinter to print human meniscus on the space station

The knee is not only one of the largest and most complex joints in the body—it is also easily injured. In fact, one of the most common orthopedic injuries is the tearing of the meniscus, a half-moon-shaped piece of cartilage in the knee. Each knee has two menisci that allow the joint to move freely. Current treatments for a torn meniscus are less than ideal, involving removing or repairing the torn segment, which can ultimately lead to increased risk of arthritis or knee replacement, as the affected joint loses its cushioning.
To improve patient care on Earth and develop more effective ways of treating torn tissues, researchers from Redwire Space are turning to the microgravity environment of the International Space Station (ISS) National Laboratory.
Redwire's upgraded BioFabrication Facility (or BFF) launched to the space station in November.
NASA to reveal crew members in April for flight around Moon
Thursday, 09 March 2023 20:29 Write a comment
NASA will announce the names next month of the four astronauts—three Americans and one Canadian—who will fly around the Moon next year, the head of the US space agency said Thursday.
NASA administrator Bill Nelson said the crew members of the mission known as Artemis 2 would be revealed on April 3.
"Astronauts—three from America and one from Canada—will fly around the moon and they'll test NASA's Space Launch System, which is our rocket, and the spacecraft called Orion," Nelson said.
The first Artemis mission wrapped up in December with an uncrewed Orion capsule returning safely to Earth after a 25-day journey around the Moon.
Artemis 2, scheduled to take place in late November 2024, will take a four-person crew around the Moon but without landing on it.
The ambitious program aims to return humans to the Moon for the first time since the historic Apollo missions ended in 1972.

CHEOPS mission extended
Thursday, 09 March 2023 18:13 Write a comment
After more than three years in orbit, the mission of the CHEOPS space telescope has just been extended. Led by the University of Bern in collaboration with the University of Geneva, CHEOPS is a joint mission of the European Space Agency (ESA) and Switzerland.
On March 7th, ESA's Science Programme Committee has confirmed its continued operations to 2026 and an indicative extension to 2029, contingent upon ongoing commitments from national contributors and partners. Since its launch in December 2019, the satellite's extremely precise measurements have contributed to several key discoveries in the field of exoplanets. The extension will make it possible to study these fascinating worlds around other stars in even more detail.
Scientists call for global push to eliminate space junk
Thursday, 09 March 2023 18:00 Write a comment
Scientists have called for a legally binding treaty to ensure Earth's orbit isn't irreparably harmed by the future expansion of the global space industry.
In the week that nearly 200 countries agreed to a treaty to protect the high seas after a 20-year process, the experts believe society needs to take the lessons learned from one part of our planet to another.
The number of satellites in orbit is expected to increase from 9,000 today to over 60,000 by 2030, with estimates suggesting there are already more than 100 trillion untracked pieces of old satellites circling the planet.
While such technology is used to provide a huge range of social and environmental benefits, there are fears the predicted growth of the industry could make large parts of Earth's orbit unusable.
An international collaboration of experts in fields including satellite technology and ocean plastic pollution say this demonstrates the urgent need for global consensus on how best to govern Earth's orbit.

How does Galileo help other space missions?
Thursday, 09 March 2023 10:30 Write a comment
In 2023 satnav receivers are everywhere: in our phones, our cars, and drones, in fixed infrastructure, aboard boats, trains and aircraft. They are also in space: more than 95% of all the satellites in low-Earth orbit carry satnav receivers to calculate their position. The additional signals from Europe’s Galileo satellites are providing a big boost to the coverage, availability, redundancy, and accuracy of spaceborne receivers, in turn enlarging the possible scope of future missions, and extending the useful range of satnav much further out into space – to the Moon and beyond.
Distant star TOI-700 has two potentially habitable planets

NASA recently announced the discovery of a new, Earth-sized planet in the habitable zone of a nearby star called TOI-700. We are two of the astronomers who led the discovery of this planet, called TOI-700 e. TOI-700 e is just over 100 light years from Earth - too far away for humans to visit - but we do know that it is similar in size to the Earth, likely rocky in composition and could potential Astronomers find missing link for water in the Solar System

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected gaseous water in the planet-forming disc around the star V883 Orionis. This water carries a chemical signature that explains the journey of water from star-forming gas clouds to planets, and supports the idea that water on Earth is even older than our Sun.
