(KWTX) - SpaceX, which operates a rocket test facility in McGregor, west of Waco, has been selected to provide launch services for the two foundational elements of the Gateway , NASA's first long-term orbiting Moon outpost.
The Gateway, about a sixth the size of the International Space Station, will function as an orbiting way station and a rendezvous point for Artemis astronauts traveling to lunar orbit on their way to the Moon.

Magnetic interactions between the newfound planet, designated Gliese 1151b, and its host star are the likely source of low-frequency radio emission recently detected from this system.

"Planets in close-in orbits are embedded in a magnetized stellar wind from the expanding stellar corona," Professor Suvrath Mahadevan from the Department of Astronomy & Astrophysics at the Pennsylvania State University and colleagues wrote in their paper.

With further study, says Daylan, this bright star and its many planets could be critical to understanding how planets take shape and evolve. “When it comes to characterizing planetary atmospheres around sun-like stars, this is likely one of the best targets we will ever get,” he says of the results he presented earlier in the month at the 237th meeting of the American Astronomical Society.

Using three different telescopes, an international team of researchers has found patterns in the light coming from an X-ray source which suggest that it is ejecting a stream of particles, diffusing into its surroundings. To their surprise, the signature of this wind could be seen in visible light.
In 1993, scientists discovered one such X-ray transient upon its outburst – known as "GRS 1716-249". After twenty-three years of quintessence, it had another episode in 2016 which gave astronomers the golden chance to observe its behavior. The team, led by Virginia A. Cuneo of Instituto de Astrofisica de Canarias in Spain, published their results in the October issue of Monthly Notices of the Royal Astronomical Society .
Multiple ISS National Lab-Sponsored Microbial Research Investigations Presently Being Performed

The new Quintillion-ATLAS ground station is located at 72 degrees latitude in Utqiagvik, Alaska, on the coast of the Arctic Ocean. The 3.7-meter antenna supports S and X band transmission and expects to see up to 12 satellite passes daily. Offering both occasional use and ground station as a service arrangements, the partnership provides a turnkey solution for satellite operators.
