NASA and SpaceX are targeting no earlier than 1:45 a.m. EST Monday, Feb. 27, 2023, for the launch of the agency’s Crew-5 mission to the International Space Station.
The four Crew-6 crewmates – Commander Stephen Bowen, Pilot Warren “Woody” Hoburg, Mission Specialist UAE (United Arab Emirates) astronaut Sultan Alneyadi, and Mission Specialist Roscosmos cosmonaut Andrey Fedyaev – will dock the Dragon spacecraft, named Endeavour, to the forward port on the space station’s Harmony module about 23 hours after liftoff.
Crew-6’s science mission includes cutting edge research aimed at keeping astronauts and spacecraft safe during deep space exploration, and studies that could lead to improved medical treatments for humans back on Earth. Experiments will include studies of how particular materials burn in microgravity, tissue chip research on heart, brain, and cartilage functions, and an investigation that will collect microbial samples from the outside of the space station. These are just some of the more than 200 science experiments and technology demonstrations that will take place during their mission.
You can watch the launch live on NASA TV, NASA.gov, the NASA app, and on social media (@NASA).
In the 1980s, scientists discovered a gaping hole in Earth’s ozone layer, caused by humanmade chemicals. But thanks to the historical Montreal Protocol, the world came together to take bold action to save our planet. Decades later, we can see the steady recovery of the ozone hole. How did we do it? And what does space have to do with it? Join us as we explore the journey of the ozone hole, from its alarming discovery to the incredible strides made to fix it, and how satellites are helping us track its recovery.

The Webb observations which revealed this small asteroid were not originally designed to hunt for new asteroids — in fact, they were calibration images of the main-belt asteroid (10920) 1998 BC1, which astronomers discovered in 1998, but the calibration team considered them to have failed for technical reasons due to the brightness of the target and an offset telescope pointing. Despite this, the data on asteroid 10920 were used by the team to establish and test a new technique to constrain an object’s orbit and to estimate its size. The validity of the method was demonstrated for asteroid 10920 using Webb observations combined with data from ground-based telescopes and ESA’s Gaia mission.
In the course of the analysis of Webb’s data, the team found the smaller and previously unknown interloper in the same field of view. The team’s results suggest the object measures 100–200 meters, occupies a very low-inclination orbit, and was located in the inner main-belt region at the time of the Webb observations.

The Cardinal Heart experiment used three-dimensional engineered heart tissues, seen in this clip, to study the effects of microgravity on the human heart. The investigation, which took place on station in 2021, confirmed that microgravity exposure causes significant changes in heart cell function and gene expression that could lead to damage.
Scheduled to launch on NASA’s SpaceX CRS-27 resupply mission in March, Cardinal Heart 2.0 takes this research one step further to test whether certain drugs can reduce or prevent microgravity-induced changes—which could also enable the development of countermeasures for patients at high risk of developing heart disease back on Earth.

During a break from looking at planets around other stars, ESA’s CHaracterising ExOPlanet Satellite (Cheops) mission has observed a dwarf planet in our own Solar System and made a decisive contribution to the discovery of a dense ring of material around it.
Studying these dwarf planets is difficult because of their small sizes and extreme distances. Quaoar itself orbits the Sun at almost 44 times the Sun-Earth distance. So, occultations are particularly valuable tools. Until recently, however, it has been difficult to predict exactly when and where they will take place.
For an occultation to occur, the alignment between the occulting object (here the TNO), the star, and the observing telescope must be extremely precise. In the past, it has been almost impossible to meet the stringent accuracy requirements to be certain of seeing an event. Nevertheless, to pursue this goal the European Research Council Lucky Star project, coordinated by Bruno Sicardy, Sorbonne University & Paris Observatory – PSL (LESIA), was created to predict upcoming occultations by TNOs, and to co-ordinate the observation of these events from professional and amateur observatories around the globe.

A grand odyssey of exploration is about to begin. Humankind’s next bold mission to the outer Solar System, ESA’s Jupiter Icy Moons Explorer, Juice, is poised to explore giant planet Jupiter and its largest moons. These intriguing worlds have piqued our curiosity ever since Galileo first raised his telescope to the planet and discovered its four largest moons: Io, Europa, Ganymede and Callisto, three of which are thought to harbour underground oceans.
Early space probes visiting the Jovian system have raised more questions than answers. But thanks to Juice, many of those answers are now within reach. ESA is launching the spacecraft in April 2023 on an eight-year journey to the distant planet.
To uncover the hidden secrets of these mysterious worlds, Juice is equipped with the most powerful science instruments ever sent to the outer Solar System. The spacecraft will face many dangers along the way: radiation, extreme temperatures, and the vast gravitational pull of Jupiter, all while operating hundreds of millions of kilometres from Earth. But in the safe hands of ESA’s operators to guide it safely through these challenges, the dangers will be worth it for the science that Juice is destined to uncover.
The countdown to this new era of Jupiter system exploration has begun. Stay tuned: www.esa.int/juice

Gravity is the force that keeps us on our planet by drawing us so powerfully towards its centre. It has much the same effect on everything else floating in the cosmos, as long as it is big enough. All objects in the Universe are subject to their own force of gravity. It is one of the fundamental forces of our Universe.
As gravity pulls matter towards other matter, a sphere forms. Why? Only a sphere allows every point on its surface to have the same distance from the centre, so that no part of the object can further ‘fall’ toward its centre.
Smaller objects in space are spared from the overwhelming power of gravity, which is why we see asteroids that look like pieces of rubble. Why do these bodies have the shape that they have? Their shape arises from a simple electrostatic force.

Work to do outside the space station, honoring a pair of former astronauts, and a milestone on Mars … a few of the stories to tell you about – This Week at NASA!
Astronauts with their sights on the Moon receive world-class geology training during the fifth edition of ESA’s Pangaea campaign.
ESA astronaut Alexander Gerst and NASA’s Stephanie Wilson joined the course to learn how to read a landscape, collect scientifically relevant rocks and effectively communicate their geological observations. From choosing landing sites for a future Artemis mission, to designing science operations for a moonwalk, the course challenges space explorers to become field scientists.
The astronauts gather a wealth of geological knowledge and learn how to be the eyes and ears of scientists on the ground through a balanced mix of theory and field trips across Europe. A crew of leading European planetary scientists and engineers make sure the trainees work in tandem using the best geology observation techniques.
The course began in September 2022 in the Italian Dolomites with lessons on martian geology and asteroids at the Bletterbach canyon.
During the second leg of the training, Alexander and Stephanie followed the footsteps of Apollo astronauts to study the Ries crater in Germany, one of the best-preserved impact craters on Earth, where American crews trained before their flight to the Moon.
The astronauts travelled to the Spanish Canary Island of Lanzarote for an intense week of training in November 2022, where they learned about the geological interactions between volcanic activity and water – two key factors in the search for life.

On Nov. 16, 2022, the Orion spacecraft launched aboard the Space Launch System (SLS) rocket from NASA’s Kennedy Space Center and embarked on the #Artemis I mission to the Moon and back. Orion orbited the Moon, getting as close as 79 miles to the lunar surface, and successfully splashed back down to Earth 25.5 days later on Dec. 11.
Four RS-25 engines and two five-segment solid rocket boosters provided more than 8.8 million pounds of thrust for SLS during liftoff and flight. Thanks in part to development of a new RS-25 engine controller that checks engine health 50 times per second, engineers were able to collect more than 100 measurements on pressures, temperatures, flows, speeds, and vibrations on the four RS-25 engines that helped power Artemis I. The preliminary post-flight data indicates that all SLS systems performed exceptionally and that the designs are ready to support a crewed flight on Artemis II.
The Artemis II mission will bring us closer to establishing a sustained human presence on the lunar surface and landing the first woman and first person of color on the Moon.
This video was captured from the Launch Pad 39B perimeter and was used by engineers to monitor and track the rocket during flight.

On Tuesday, Jan. 31 Vice President Kamala Harris awarded former NASA astronauts Douglas Hurley and Robert Behnken the Congressional Space Medal of Honor. Hurley and Behnken received the award for bravery in NASA’s SpaceX Demonstration Mission-2 (Demo-2) to the International Space Station in 2020.
NASA’s Commercial Crew Program began a new era of human spaceflight as American astronauts launched from American soil on an American rocket to the International Space Station. Behnken and Hurley flew on SpaceX’s Crew Dragon spacecraft, which lifted off on a Falcon 9 rocket on May 30, 2020, from Launch Complex 39A in Florida. This mission was the final flight test for SpaceX, validating the company’s crew transportation system, including the launch pad, rocket, spacecraft, and operational capabilities.
Once in orbit, Behnken and Hurley were welcomed aboard the ISS, and became members of the Expedition 63 crew. They performed tests on Crew Dragon in addition to conducting research and other tasks with the space station crew. Upon conclusion of the mission, the Crew Dragon autonomously undocked, re-entered the Earth’s atmosphere and splashed down just off Florida’s Atlantic Coast. Demo-2 was the final step before NASA’s Commercial Crew Program certified Crew Dragon for operational, long-duration missions to the space station, enabling NASA to continue important research and technology investigations onboard the station.

The “lunar hay fever”, as @NASA astronaut Harrison Schmitt described it during the Apollo 17 mission created symptoms in all 12 people who have stepped on the Moon. From sneezing to nasal congestion, in some cases it took days for the reactions to fade. Inside the spacecraft, the dust smelt like burnt gunpowder.
The Moon missions left an unanswered question of lunar exploration – one that could affect humanity’s next steps in the Solar System: can lunar dust jeopardise human health?

Greenhouse gas emissions decreased a little during the first year of COVID, but not enough to make a lasting impact.
Less travel and cars on the road meant improved air quality. But greenhouse gases that cause climate change only decreased a little because we were still heating and cooling our homes, so these gases continued to build up in our atmosphere. NASA climate change scientist Lesley Ott tells us more about what scientists discovered.
Did you know that ESA is researching human hibernation for long distance spaceflight to Mars or beyond?
Hibernating astronauts could be the best way to save mission costs, reduce the size of spacecraft by a third and keep crew healthy on their way to Mars. An ESA-led investigation suggests that human hibernation goes beyond the realm of science-fiction and may become a game-changing technique for space travel.
When packing for a return flight to the Red Planet, space engineers account for around two years’ worth of food and water for the crew.
Torpor during hibernation is an induced state that reduces the metabolic rate of an organism. This ‘suspended animation’ is a common mechanism in animals who wish to preserve energy. Reducing the metabolic rate of a crew en route to Mars down to 25% of the normal state would dramatically cut down the amount of supplies and habitat size, making long-duration exploration more feasible.
Mimicking therapeutic torpor, the idea of putting human into a state of hibernation, has been around in hospitals since the 1980s – doctors can induce hypothermia to reduce metabolism during long and complex surgeries. However, it is not an active reduction of energy and misses most of the advantages of torpor. Studies on hibernation to visit other planets could offer new potential applications for patient care on Earth.
Animals hibernate to survive periods of cold and food or water scarcity, reducing their heart rate, breathing and other vital functions to a fraction of their normal life, while body temperature lowers close to ambient temperature. Tardigrades, frogs and reptiles are very good at it. Lower testosterone levels seem to aid long hibernation in mammals, estrogens in humans strongly regulate energy metabolism.
With the crew at rest for long periods, artificial intelligence will come into play during anomalies and emergencies.
The possibilities of hibernation for medical use is of particular interest to the European research community and could transform how we approach many severe illnesses.
Inducing torpor is already used in some medical environments such as surgical theathers to replace anesthesia in those patients allergic to anesthetic drugs.
