North Korea fires suspected ballistic missile into sea
North Korea fired what appeared to be a ballistic missile into the sea on Wednesday, South Korea and Japan said, in the first such launch by Pyongyang this year.
In the decade since Kim Jong Un took power, North Korea has made rapid progress in its military technology at the cost of international sanctions.

Up until she served in the Peace Corps in Malawi, Rachel Bielajew was open to a career reboot. Having studied nuclear engineering as an undergraduate at the University of Michigan at Ann Arbor, graduate school had been on her mind. But seeing the drastic impacts of climate change play out in real-time in Malawi - the lives of the country's subsistence farmers swing wildly, depending on the rains Supernovae and life on Earth appears closely connected
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
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.

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.
Webb will see farther into our origins: from the Universe's first galaxies, to the birth
