Curiosity rover reaches its 3,000th day on Mars
Monday, 11 January 2021 20:52 Write a comment
As the rover has continued to ascend Mount Sharp, it's found distinctive benchlike rock formations.
It's been 3,000 Martian days, or sols, since Curiosity touched down on Mars on Aug. 6, 2012, and the rover keeps making new discoveries during its gradual climb up Mount Sharp, the 3-mile-tall (5-kilometer-tall) mountain it has been exploring since 2014. Geologists were intrigued to see a series of rock "benches" in the most recent panorama from the mission.
Stitched together from 122 images taken on Nov. 18, 2020, the mission's 2,946th sol, the panorama was captured by the Mast Camera, or Mastcam, which serves as the rover's main "eyes.

SpaceX's next idea: Catch Super Heavy boosters with the launch tower
Monday, 11 January 2021 14:14 Write a comment
SpaceX is getting closer and closer to realizing the design for its Starship and Super Heavy launch system. Once complete, it will be the world's first fully reusable launch system and will facilitate trips to low Earth orbit (LEO), the moon and Mars. Construction began on the system's booster element (Super Heavy) this past summer and, according to a recent tweet by Musk, will be "caught" by its launch tower.
The tweet came (as they often do) in response to a question from one of Musk's followers. In this case, it was a space designer who goes by the Twitter handle Erc X (@ErcXspace) who produced a video that illustrates what the Super Heavy might look like as it returns to its landing site. The video is captioned with a question: "Accurate Super Heavy Descent profile?"

Musk responded by tweeting:
"We're going to try to catch the Super Heavy Booster with the launch tower arm, using the grid fins to take the load… Saves mass & cost of legs & enables immediate repositioning of booster on to launch mount—ready to refly in under an hour.

Reconstructing the solar system's original architecture
Monday, 11 January 2021 13:19 Write a comment
As the solar system was developing, the giant planets (Jupiter and Saturn) formed very early, and as they grew, they migrated both closer to and further away from the sun to stay in gravitationally stable orbits.
The gravitational effect of these massive objects caused immense reshuffling of other planetary bodies that were forming at the time, meaning that the current locations of many planetary bodies in our solar system are not where they originally formed.
Lawrence Livermore National Laboratory (LLNL) scientists set out to reconstruct these original formation locations by studying the isotopic compositions of different groups of meteorites that all derived from the asteroid belt (between Mars and Jupiter). The asteroid belt is the source of almost all of Earth's meteorites, but the material that makes up the asteroid belt formed from sweeping of materials all over the solar system.
