Scientists found the routes by computing how "millions" of Solar System orbits fit inside known space manifolds, or arch structures that extend from the asteroid belt.
Nasdaq said on Friday it will remove shares of four Chinese construction and manufacturing companies from indexes it maintains in response to a U.S. order restricting purchase of their shares. The securities, which are not traded on the Nasdaq exchange, will be removed from the indexes on Dec. 21. A White House executive order last month barred U.S. investors from buying securities of blacklisted firms, starting in November 2021.

Studies offer tips on lessening spaceflight-related risk | Cornell Chronicle
The Earth's atmosphere, featuring the aurora borealis, is pictured from the International Space Station.
Space travel, illnesses like COVID-19 and climbing Mount Everest can trigger the body's stress response systems in similar ways, according to new studies by Weill Cornell Medicine, space agencies and other investigators.
The discoveries , including new maps of the abundance of mutations and immune changes found in blood cells during spaceflight, may lead to new ways to protect space travelers. They may also provide insights on caring for Earth-bound patients with illnesses that trigger similar physiological responses.
Virgin Galactic stops space travel effort in New Mexico
The Virgin Galactics’ latest spaceflight did not fully burn out as the engine of its spaceship vehicle “Unity” attempted to fly over New Mexico on Saturday.
In the absence of any passengers, C.J. Directed by Starkov and Dave McKay. The Virgin Galactic aims to reach the edge of space for the third time, from its operating base in New Mexico on its maiden spaceflight. The spacecraft returned to the runway in the Spaceport United States, about 50 miles north of Los Cruces.
The start of the Sensoria M3 lunar mission is like Groundhog Day — Commander's Report: Lunar Day
Dr. Michaela Musilova is the director of Hawaii Space Exploration Analog and Simulation ( HI-SEAS ) program, which conducts analog missions to the moon and Mars for scientific research at a habitat on the volcano Mauna Loa. Currently, she is in command of the two-week Selene II mission and contributed this report to Space.com's Expert Voices: Op-Ed & Insights .

My space-lag is also a bit emotional. I'm still getting over saying goodbye to the wonderful Selene II crew and creating space in my heart to accommodate my new space family of SENSORIA M3. The mission is part of the SENSORIA Program, which aims to support underrepresented groups within the space sector. This transition time is never easy, but I'm sure that I'll get through this easily with the support of my lunar friends.

DNA: Analysis of the future of space travel
Fiery crash of SpaceX's Starship rocket ignites dreams of future spaceflight
SpaceX's Starship prototype, Serial Number 8 (SN8), takes off over Boca Chica Beach in South Texas on December 9. The 165-foot craft crashed on landing but generated enough data to be considered a resounding success.

The engines ignited with a burst of fiery exhaust, kicking up a bloom of brown dust, as the 165-foot-tall rocket, known as Serial Number 8 (SN8), made its way into the blue sky over Boca Chica Beach, outside Brownsville, Texas. The prototype seemed to stagger under its 110-ton weight, despite a trio of engines—each producing half a million pounds of thrust—propelling it through the air.

"For the first time, we can see the cellular and molecular changes that may underlie the heart conditions seen in astronaut studies," says Karen Ocorr, Ph.D. , assistant professor in the Development, Aging and Regeneration Program at Sanford Burnham Prebys and co-senior author of the study. "We initiated this study to understand the effects of microgravity on the heart, and now we have a roadmap we can use to start to develop strategies to keep astronaut hearts strong and healthy."
USGS Supports the 2020 National Space Policy
"The USGS plays a key role in America's space exploration efforts, from mapping Earth's critical minerals, monitoring hazards, mapping critical environments, and characterizing our lands and resources," said Reilly. "In addition, we continue to support our NASA colleagues in extra-terrestrial mapping of the Moon and Mars and provide mapping support for those missions, the latest of which is the Perseverance Rover set to land on Mars on February 18 next year."

In all these activities, the USGS will leverage new commercial and international space capabilities in partnerships to deliver actionable information at scales and timeframes relevant to decision makers.
