Supernovae and life on Earth appears closely connected
Write a comment
Evidence demonstrates a close connection between the fraction of organic matter buried in sediments and changes in supernovae occurrence. This correlation is apparent during the last 3.5 billion years and in closer detail over the previous 500 million years.
The correlation indicates that supernovae have set essential conditions under which life on Earth had to exist. This is concluded in Rogozin says Baikonur security strengthened amid Kazakhstan protests

The Russian forces have strengthened armed protection over the Baikonur Cosmodrome's key objects amid rallies in Kazakhstan, Russian State Space Corporation Roscosmos Head Dmitry Rogozin said on Wednesday.
Rogozin noted that the situation at the Baikonur Cosmodrome is calm as "Roscosmos' branches, law enforcement bodies, city services and organizations are working in the routine mode." Webb Secondary Mirror Deployment Confirmed

The Webb teams has deployed the observatory's secondary mirror support structure. When light from the distant universe hits Webb's iconic 18 gold primary mirrors, it will reflect off and hit the smaller, 2.4-foot (.74-meter) secondary mirror, which will direct the light into its instruments.
The secondary mirror is supported by three lightweight deployable struts that are each almost 25 fe Earth isn't 'super' because the Sun had rings before planets

Before the solar system had planets, the sun had rings - bands of dust and gas similar to Saturn's rings - that likely played a role in Earth's formation, according to a new study. "In the solar system, something happened to prevent the Earth from growing to become a much larger type of terrestrial planet called a super-Earth ," said Rice University astrophysicist Andre Izidoro, referring to the NASA releases autonomous flight termination unit software to industry

NASA has provided an advance release of its NASA Autonomous Flight Termination Unit (NAFTU) software code to the launch industry, a critical milestone toward the final certification of NAFTU, which is on-track for February 2022.
NAFTU is a game-changing command and control system available to launch vehicle providers for use at all U.S. launch ranges in ensuring public safety during launch New Year’s science in space for a healthier life

Another year passes, and our muscles, bones, eyes and ears deteriorate as we age – even more so in space. Reactions in ESA astronaut Matthias Maurer’s body after barely two months on the International Space Station are giving European scientists clues on how to fight the downsides of growing old on Earth.
Webb telescope deploys flap that will keep it oriented during its mission
Write a comment
On December 25, 2021, astronomers and space exploration enthusiasts got the greatest Christmas present of all—after years of delays, cost overruns and additional testing, the James Webb Space Telescope (JWST) launched from Europe's Spaceport in Kourou, French Guiana. In a real nail-biter, the Ariane 5 rocket and its precious payload reached orbit without a hitch. But as is so often the case, the deployment of the JWST was just the first in a series of "hurry-up-and-wait" episodes.
Typically, periods of waiting are accompanied by plenty of worry and doubt. Luckily, there have been several positive developments since the JWST launched that could alleviate these anxieties. The latest is that the telescope successfully deployed its aft momentum flap, an instrument that will keep the telescope oriented during its mission. The news was announced yesterday (December 30) via @NASAWebb, NASA's official Twitter account for the Webb telescope, and the JWST page at NASA Blogs.
According to NASA Blogs, the deployment of the aft momentum flap began at 09:00 AM EST (06:00 AM PST) and lasted about eight minutes. During this time, the mission team released the flap's hold-down devices while a spring brought the flap into its final position.

Highlights of the launch campaign for the James Webb Space Telescope, from its arrival at Europe’s Spaceport in Kourou, French Guiana, weeks of launch preparations, to launch on board an Ariane 5, and separation of the spacecraft and solar panel deployment.
Now in space and on its way to L2, Webb will undergo a complex unfolding sequence. In the months after, the instruments will be turned on and their capabilities tested. After half a year in space, Webb will start its routine science observations.

2029 will be the perfect year to launch a mission to Sedna
Write a comment
Object 90377 Sedna—a distant trans-Neptunian object known best for its highly elliptical, 11,390-year long orbit—is currently on its way toward perihelion (its closest approach to the sun) in 2076. After that, Sedna will swing out into deep space again and won't be back for millennia, making this flyby a once-in-a-lifetime (or, once in ~113 lifetimes) opportunity to study an object from the far reaches of our solar system. There are no missions to Sedna in the works just yet, but astronomers are beginning to plan for the possibility, and the ideal launch date for such a mission is approaching fast, with two of the best launch windows coming up in 2029 and 2034.
Sedna was discovered in 2003 by Caltech astronomer Mike Brown and his team, and was one of a series of potential dwarf planets (alongside similar-sized bodies like Haumea, Makemake, and Eris) whose discovery led to the demotion of Pluto in 2006. As best we can tell from a distance, Sedna is about the same size as Ceres, the largest object in the asteroid belt, but its composition and origins are different.
