NASA will host a media teleconference at 11 a.m. EST on Thursday, Dec. 22, to discuss the ongoing investigation of an external leak that occurred Dec. 14, from the Roscosmos Soyuz MS-22 spacecraft docked to the Rassvet module of the International Space Station.

Live audio of the call will stream on the agency’s website at:

https://www.nasa.gov/live

Briefing participants include:

  • Joel Montalbano, manager, International Space Station Program, NASA’s Johnson Space Center in Houston
  • Sergei Krikalev, executive director, Human Space Flight Programs, Roscosmos

Media interested in participating by phone must contact the Johnson newsroom no later than one hour before the start of the call at: 281-483-5111 or jsccommu@mail.nasa.gov.

The leak was first detected around 7:45 p.m. EST Dec. 14, when pressure sensors in the spacecraft’s cooling loop showed low readings. At the time of the leak, Roscosmos cosmonauts were preparing to conduct a spacewalk. The spacewalk was postponed, so no crew members exited the space station or were exposed to the leaking coolant.

NASA provided an additional inspection of the Soyuz exterior using the station’s Canadarm2 robotic arm on Dec. 18. Images and data are being analyzed by Roscosmos. The agency also is closely monitoring Soyuz spacecraft temperatures, which remain within acceptable limits. NASA and Roscosmos are continuing to work together on a course of action following the ongoing analysis.

The Soyuz MS-22 spacecraft carried NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin into space after launching from the Baikonur Cosmodrome in Kazakhstan on Sept. 21.

The recent buzz surrounding the Joro spider on social media has caused a stir, with exaggerated stories painting them as a potential threat. However, according to expert entomologist Theresa Dellinger from Virginia Tech, there is no cause for alarm when it comes to these arachnids. Here are some key points that shed light on the reality of Joro spiders:

  1. Origin and Spread: Joro spiders are native to east Asia and likely made their way to the U.S. through imported materials. While they have been sighted in several states, including Georgia, Tennessee, North Carolina, and South Carolina, they have not been reported in Virginia yet.
  2. Similarity to Other Spider Species: Joro spiders belong to the orb weaver family, much like other spider species found in the U.S. such as garden orb weavers and golden silk orbs. While they may look intimidating due to their size, they are not aggressive towards humans.
  3. Behavior and Concerns: Joro spiders are not known to pose any medical concerns, unless someone is specifically allergic to spider bites. They are shy creatures that feed on insects and play a role in controlling pest populations.
  4. Environmental Impact: As a non-native species, Joro spiders may impact the ecosystem by competing with native spider species. However, the long-term effects are still being studied.
  5. Precautions: Contrary to sensationalized claims, Joro spiders do not invade homes and do not require yard treatments. If they become a nuisance, they can be easily removed using a broom or insecticide spray.

Theresa Dellinger, an expert in entomology, provides valuable insights into the behavior and impact of Joro spiders, debunking myths and offering practical advice for coexisting with these creatures. As with any wildlife encounter, understanding the facts can help dispel unnecessary fear and promote a harmonious relationship with nature.
