Chinese Satellite Close Call

Orbiting the Earth is complicated enough without the Russians and other creating new obstacles. China recently learned about these hazards when one of its science satellites came close to colliding with debris created last November from a Russian anti-satellite test. China’s satellite missed the debris by about 48 feet, which the Chinese government called “extremely dangerous.” No kidding.

That same debris has threatened the International Space Station as well, which Russia also funds and occupies. It is not clear why Russia would endanger its own cosmonauts residing on the station.

That said, it is interesting that China is upset with Russia after similarly creating space debris back in 2007 part of its own anti-satellite experiments. The space community was similarly frustrated with the impact on orbiting spacecraft. In fact, the ISS had to dodge that debris as well last November.

Everyone’s spacecraft are at risk when we test weapons in space. We have to decide if we want to conduct science or simply give way to orbiting debris forevermore.

If you are a Trekkie, you will want to stay abreast of some of the new and returning Star Trek series. I have provided some dates for your calendar.

— Star Trek: Discovery: Season 4 returns with new episodes on February 10th after taking a short break. Here is the trailer for the season. You can learn more about the series and watch earlier episodes at Paramount Plus.

— Star Trek: Picard: The series returns with its second season on March 3rd. Check out the trailer and you may recognize a few faces, including Q, Guinan, and the Borg as well. You can find season 1 episodes at Paramount Plus.

— Star Trek: Strange New Worlds: This new series premieres on May 5th. The series will follow Captain Pike and his time on the USS Enterprise. You can meet the actors of this series via this trailer.

NASA and MIT Found More Than 5,000 Exoplanet Candidates

The volume of possible new worlds continues to expand with the work of the MIT-led NASA mission to observe the heavens for potential exoplanet candidates. Since 2018, the Transiting Exoplanet Survey Satellite (TESS) program has been monitoring stars for temporary drops in brightness caused by planetary transits (the mapping of the initial two years of viewing is provided above). With the addition of new candidates from July 2020 to June 2021, the count of potential exoplanets now exceeds 5,000. Potential candidates will be studied to learn more about their characteristics. TESS’s mission goal has been to discover 50 planets of size less than 4 Earth radii with measured masses.

You can read more about some of TESS’s earlier exoplanet discoveries (shown below and here). For instance, L 98-59b is about 80 percent Earth’s size and orbits L 98-59, an M dwarf about one-third the mass of the Sun. L98-59 is about 35 light-years away.

NASA’s Travel Agency

If you are getting tired of staying home these days, NASA has some fun destinations in mind for you. Late last year, NASA’s Jet Propulsion Laboratory (JPL) put together “Visions of the Future” to show you where the space agency hopes to go someday. You may not want to pack just yet, but whether it is this solar system or some other solar system, NASA wants to help.

The poster above for Kepler-16b comes with this enticing description:

Like Luke Skywalker’s planet “Tatooine” in Star Wars, Kepler-16b orbits a pair of stars. Depicted here as a terrestrial planet, Kepler-16b might also be a gas giant like Saturn. Prospects for life on this unusual world aren’t good, as it has a temperature similar to that of dry ice. But the discovery indicates that the movie’s iconic double-sunset is anything but science fiction.

You might also enjoy this NASA video showing some space activities in these prime locations.

I dropped in a few more posters below, but be sure to check out all of them. A big thanks also to the folks at JPL for these fun images. The 14 posters were created by nine artists, designers, and illustrators.

Of course, these free photos are already being sold on Etsy.com and elsewhere as posters and t-shirts.
