How Mars lost its oceans
Write a comment
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 Prepares to Join Two Major Parts for Artemis II Core Stage

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.

SENER Aeroespacial, a company of the SENER engineering and technology group, and Australian launch services company Gilmour Space Technologies, are working together on an Autonomous Flight Termination System (AFTS) for the Eris launch vehicle, which is being developed for the small satellite market.
The AFTS is a smart Hardware/Software unit with autonomous decision-making capacity respons Predicting the efficiency of oxygen-evolving electrolysis on the Moon and Mars

Scientists at The University of Manchester and The University of Glasgow have provided more insight into the possibility of establishing a pathway to generate oxygen for humans to potentially call the Moon or Mars 'home' for extended periods of time.

Research has shown that the Earth trails an asteroid barely a kilometre across in its orbit about the Sun - only the second such body to have ever been spotted. It goes round the Sun on average two months ahead of the Earth, dancing around in front like an excited herald of our coming.
This object, known as 2020 XL5, was first spotted in December 2020 using Pan-STARRS telescopes on the sum Riding a laser to Mars

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.
Protecting dark and quiet skies from satellite constellation interference

If you've ever tried to star gaze in a residential or urban area, you know that a streetlight or even the lights from a nearby town can greatly interfere with your ability to identify Orion's Belt and see a rare comet or other celestial bodies. But what is more of a disappointment for us is a cosmic disruption for scientists and others in the space industry.
To preserve this vital characteristic of the universe, a new International Astronomical Union Centre for the Protection of the Dark Sky from Satellite Constellation Interference has been established.
Siegfried Eggl, faculty member in the Department of Aerospace Engineering at the University of Illinois Urbana-Champaign and Robert Gruendl in Illinois' Dept. of Astronomy have been selected to participate. They are both members of the Center for AstroPhysical Surveys in the National Center for Supercomputing Applications at UIUC.
Monitoring crop health across the Netherlands

The Copernicus Sentinel satellite missions measure and image our planet in different ways to return a wealth of complementary information so that we can understand and track how our world is changing, and how to better manage our environment and resources. Thanks to the benefits of different types of data from two particular Copernicus Sentinel missions and an ingenious new dataset tool, people working in the agriculture sector, but who are not satellite data experts, can monitor the health and development of crops, right down to each crop in individual fields.

If we were to talk about our bodies in the technical terms that we typically use to talk about spacecraft, our bones, muscles and ligaments would be our 'hardware', our brain the 'central processing unit (CPU)', and our nervous system the 'software'.
