Saturn's moon Titan looks very much like Earth from space, with rivers, lakes, and seas filled by rain tumbling through a thick atmosphere. While these landscapes may look familiar, they are composed of materials that are undoubtedly different - liquid methane streams streak Titan's icy surface and nitrogen winds build hydrocarbon sand dunes.

The Falcon 9 rocket and Crew Dragon capsule carrying ESA astronaut Samantha Cristoforetti and NASA astronauts Kjell Lindgren, Robert “Bob” Hines and Jessica Watkins to the International Space Station lifts off from Launchpad 39A.
Collectively known as Crew-4, the four astronauts were launched at 08:52 BST/09:52 CEST Wednesday 27 April from NASA’s Kennedy Space Center in Florida USA. Transit to the Station is expected to take under 24 hours.
Samantha is the third ESA astronaut to travel to the orbital outpost in a Crew Dragon. During the journey she and Jessica will serve as mission specialists. Kjell is Crew-4

SpaceX launched four astronauts to the International Space Station for NASA on Wednesday, less than two days after completing a flight chartered by millionaires.
It's the first NASA crew comprised equally of men and women, including the first Black woman making a long-term spaceflight, Jessica Watkins.
"This is one of the most diversified, I think, crews that we've had in a really, really long time," NASA's space operations mission chief Kathy Lueders said on the eve of launch.
Solar beats nuclear at many potential settlement sites on Mars

The high efficiency, light weight and flexibility of the latest solar cell technology means photovoltaics could provide all the power needed for an extended mission to Mars, or even a permanent settlement there, according to a new analysis by scientists at the University of California, Berkeley.
Most scientists and engineers who've thought about the logistics of living on the surface of the Red Planet have assumed that nuclear power is the best alternative, in large part because of its reliability and 24/7 operation. In the past decade, miniaturized Kilopower nuclear fission reactors have advanced to the point where NASA considers them to be a safe, efficient and plentiful source of energy and key to future robotic and human exploration.

NASA's Space Launch System rocket and Orion spacecraft for the Artemis I mission arrived safely at Kennedy Space Center's Vehicle Assembly Building in Florida, the agency said Tuesday.
The SLS rocket and Orion spacecraft arrived at the assembly building after a 10-hour journey from launch pad 39B that began Monday morning, NASA confirmed.

NASA Administrator Bill Nelson said on Thursday that he has full confidence Russia will extend its cooperation with the United States on the International Space Station (ISS) based on the continuing close cooperation and warm personal relations between crews from both countries and their control teams back on earth.

Our weekend drive brought us successfully to our planned stop. The priority in this Touch and Go drive plan is to image the buttes which surround us. Mastcam will image "Blackcraig" and "Maringma" buttes which lie on our left and right respectively as we continue to head down from the pediment, and "Deepdale" butte which is ahead of us in the distance.

Determining the history of Mars, how it formed and evolved over time, has been a goal of both orbiter and rover missions to the Red Planet for decades. Analyzing data from several of these Mars missions, a team of researchers led by Steve Ruff of Arizona State University's School of Earth and Space Exploration has determined that enigmatic olivine-rich bedrock in Gusev crater and in and around J Chinese research institutions set to receive 4th batch of lunar samples

China has announced a list of research institutions that are set to receive the fourth batch of lunar samples brought back by the country's Chang'e-5 mission.
The samples, which weigh 8.768 grams, will be distributed to scientists at 11 research institutions, according to a notice issued by the Lunar Exploration and Space Program Center of the China National Space Administration.

Researchers at the Max Planck Institute for Intelligent Systems (MPI-IS), Cornell University and Shanghai Jiao Tong University have developed collectives of microrobots which can move in any desired formation. The miniature particles are capable of reconfiguring their swarm behavior quickly and robustly.

Glaciers of carbon dioxide are moving, creating deposits kilometers thick today across the south polar region of Mars, something that could have been going on more than 600,000 years, a paper by Planetary Science Institute Research Scientist Isaac Smith says.
"The CO2 deposits that were first identified in 2011 turn out to be flowing today, just like glaciers on Earth," said Smith, lead au
