NASA Prepares to Join Two Major Parts for Artemis II Core Stage
Wednesday, 09 February 2022 05:08
Technicians are preparing to connect two major parts of the Space Launch System (SLS) rocket's Artemis II core stage. On Jan. 30, technicians moved the largest part of the stage, the 130-foot liquid hydrogen tank to the vertical assembly area at NASA's Michoud Assembly Facility. Here, it will be prepared for joining with the 66-foot forward assembly.

Wednesday, 09 February 2022 05:08
It has long been known that Mars once had oceans due in part to a protective magnetic field similar to Earth's. However, the magnetic field disappeared, and new research may finally be able to explain why. Researchers recreated conditions expected in the core of Mars billions of years ago and found that the behavior of the molten metal thought to be present likely gave rise to a brief magnetic f NASA awards contract for first rocket to launch from another planet

NASA has started the early processes of constructing a $194 million small rocket that will launch from Mars, which will be the first known rocket launch from another planet.
The so-called Mars Ascent Vehicle, or MAV, has been designed to fly to Mars, receive Martian rock samples from a rover and blast back into space. It's part of a plan to return the first-ever rocks from the Red Plane Sols 3381-3382: Whence We Came

After our adventures further uphill, Curiosity is backing down hill to get to the start of the path she will take up to the "Greenheugh Pediment." We are still surrounded by amazing stratigraphy and have the benefit of having been through here before. We can fill in missing pieces of terrain, and follow up interesting observations. Mastcam and ChemCam imaging fills both needs today.
Mastca Saturn's High-Altitude Winds Generate Extraordinary Aurorae, Study Finds
Wednesday, 09 February 2022 05:08
Space scientists have discovered a never-before-seen mechanism fueling huge planetary aurorae at Saturn. A University of Leicester-led team has found that Saturn is unique among planets observed to date in that some of its aurorae are generated by swirling winds within its own atmosphere, and not just from the planet's surrounding magnetosphere.
The study, which is based on observations ma The Magnetic Field in Milky Way "Bones"
Wednesday, 09 February 2022 05:08
Star formation in the Milky Way primarily occurs in long, dense filaments of gas and dust that stretch along the spiral arms. Dubbed "bones" because they delineate the galaxy's densest skeletal spiral structures, these filaments are characterized by being at least fifty times longer than they are wide and having coherent internal motions along their lengths.
While most of the key physical NASA embarks on 3-month alignment of Webb telescope's massive mirror
Wednesday, 09 February 2022 05:08
NASA has started the tedious, precise job of aligning 18 sections of the James Webb Space Telescope's giant golden mirror.
The mirror had to be large enough to capture infrared light from the universe's earliest galaxies, but also had to be sectioned and folded in order to build and launch.
Now, NASA engineers and astronomers will attempt to reposition all 18 hexagonal sections s For clues to neutron stars, scientists probe lead nuclei's thin neutron skin
Wednesday, 09 February 2022 05:08
Nuclear physicists explore different nuclei to learn how protons and neutrons behave. For instance, they have found that nuclei made of just a few protons and neutrons typically contain close to an equal number of each. But as nuclei get heavier, they need to pack in more neutrons than protons to remain intact.
These extra neutrons tend to stick to the outer edges of heavy nuclei and form Indian Space Agency decommissions communication satellite

Riding a laser to Mars
Tuesday, 08 February 2022 17:10
Could a laser send a spacecraft to Mars? That's a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber behind the spacecraft, producing thrust from hydrogen gas and sending it to Mars in only 45 days. There, it would aerobrake in Mars' atmosphere, shuttling supplies to human colonists or, someday perhaps, even humans themselves.
In 2018, NASA challenged engineers to design a mission to Mars that would deliver a payload of at least 1,000 kilograms in no more than 45 days, as well as longer trips deep into, and out of, the solar system. The short delivery time is motivated by a desire to ferry shipments and, someday, astronauts to Mars while minimizing their exposure to the damaging effects of galactic cosmic rays and solar storms.
