How cells could help Artemis astronauts exercise
Thursday, 26 January 2023 17:50 Write a comment
In 2033, NASA and China plan to send the first crewed missions to Mars. These missions will launch every two years when Earth and Mars are at the closest points in their orbits (Mars Opposition). It will take these missions six to nine months to reach the Red Planet using conventional technology. This means that astronauts could spend up to a year and a half in microgravity, followed by months of surface operations in Martian gravity (roughly 40% of Earth gravity). This could have drastic consequences for astronaut health, including muscle atrophy, bone density loss, and psychological effects.
Aboard the International Space Station (ISS), astronauts maintain a strict exercise regimen to mitigate these effects.

Using radar images from the Copernicus Sentinel-1 mission, the animation shows the A81 iceberg breaking away from the Brunt Ice Shelf on 25 January 2023. The new berg is estimated to be around 1550 sq km, which is around the size of Greater London, and is approximately 150 m thick. It calved when the crack known as Chasm-1 split northwards severing the west part of the ice shelf.
The white square indicated the final breakpoint near the McDonald Ice Rumples.
Routine monitoring from satellites offers unparalleled views of events happening in remote regions. The Copernicus Sentinel-1 mission carries
BepiColombo and Solar Orbiter compare notes at Venus

The convergence of two spacecraft at Venus in August 2021 has given a unique insight into how the planet is able to retain its thick atmosphere without the protection of a global magnetic field.
The ESA/JAXA BepiColombo mission, en route to study Mercury, and the ESA/NASA Solar Orbiter, which is observing the sun from different perspectives, are both using a number of gravity-assists from Venus to change their trajectories and guide them on their way.

The mission to return martian samples back to Earth will see a European 2.5 metre-long robotic arm pick up tubes filled with precious soil from Mars and transfer them to a rocket for an historic interplanetary delivery.
The sophisticated robot, known as the Sample Transfer Arm or STA, will play a crucial role in the success of the Mars Sample Return campaign.
The Sample Transfer Arm is conceived to be autonomous, highly reliable and robust. The robot can perform a large range of movements with seven degrees of freedom, assisted by two cameras and a myriad of

Tiny asteroid to pass close by Earth today
Thursday, 26 January 2023 05:41 Write a comment
On Thursday, Jan. 26, a small near-Earth asteroid will have a very close encounter with our planet. Designated 2023 BU, the asteroid will zoom over the southern tip of South America at about 4:27 p.m. PST (7:27 p.m. EST) only 2,200 miles (3,600 kilometers) above the planet's surface and well within the orbit of geosynchronous satellites.

DARPA, via its Demonstration Rocket for Agile Cislunar Operations (DRACO) program, is collaborating with NASA to build a nuclear thermal rocket (NTR) engine that could expand possibilities for the space agency's future long-duration spaceflight missions. The goal is to test an NTR-enabled spacecraft in Earth orbit during the 2027 fiscal year.
