Earlier today, US astronaut astronaut Loral O’Hara as well as Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub departed from Kazakhstan on a Soyuz rocket that will take them to the International Space Station (ISS). The space station will be crowded again until the three relieved crew members, including US astronaut Frank Rubio, can return to Earth.

You can watch today’s launch at this NASA site on YouTube. You can also follow the mission via NASA’s blog.

Pic of the Week: Astronaut Frank Rubio Still at Work on the ISS

This week’s image shows astronaut Frank Rubio hard at work last year outside the International Space Station (ISS). He has now exceeded the U.S. space duration record, which was 355 days. All of this was unplanned, come as the result of a faulty Russian capsule that kept him on the station longer than his scheduled six month tour.

Mr. Rubio is set to return to Earth on September 27. At that point, he will have spent 371 days in space.

This CBS News segment discusses some of the risks related to a longer stay on the station.

Damn it, Jim! I’m a Doctor, Not a Spider!

The Star Trek name and characters have been thrown around in popular culture for years, but now scientists have locked onto them. A new group of spiders, part of the Roddenberryus genus (yes, that’s right), have been named Kirk, McCoy and Spock.

If you do not believe me, take a look at this article in the New York Times, “It’s a Spider, Not a Doctor, Captain or Vulcan.” The article quotes Dr. Bonaldo, a researcher at the Paraense Emílio Goeldi Museum in Brazil, who made this statement about the newly-named spiders:

They somewhat resemble Star Trek spaceships…Arachnologists have a long tradition of giving interesting scientific names for new genera and species, as most of us believe it is a great opportunity to acknowledge people or draw parallels with pop culture and local customs.

I expect Dr. McCoy would be yelling for weeks about this one.

JWST Spots a Promising Exoplanet

The exoplanet, some 120 light-years away, has caught the attention scientists using the James Webb Space Telescope (JWST). K2-18 b, about 8.6 times as massive as Earth, has carbon-bearing molecules in its atmosphere, including methane and carbon dioxide. This could mean the exoplanet has a hydrogen-rich atmosphere and a water ocean-covered surface (called a Hycean exoplanet).

Exoplanets of this size, between the size of Earth and Neptune, are called “sub-Neptune” exoplanets. These are the most most common type of exoplanet found to date in our galaxy.

Nikku Madhusudhan, an astronomer at the University of Cambridge and lead author of the paper announcing these results, stated:

Our findings underscore the importance of considering diverse habitable environments in the search for life elsewhere…Traditionally, the search for life on exoplanets has focused primarily on smaller rocky planets, but the larger Hycean worlds are significantly more conducive to atmospheric observations.
