The best seat in the solar system

NASA’s TESS mission continues to rack up exoplanet discoveries. One of its latest findings is a “super hot Jupiter” that orbits its star backward. Another newly discovered planet orbits both of its suns, crossing in front of both as seen from our solar system. As of Sept. 14, NASA’s exoplanet dashboard lists 4,516 confirmed exoplanets.

The first-ever crew of non-governmental astronauts will soon return to Earth. The Inspiration4 mission launched safely into orbit aboard a SpaceX Dragon crew capsule on Wednesday and is expected to return after three days in space. Counting the astronauts aboard the International Space Station and China’s new space station — who were scheduled to return to Earth on Friday morning just before the Downlink published — there were briefly 14 people in orbit, setting a new record.

Two crew members on the International Space Station will end up staying aboard for nearly a full year. NASA astronaut Mark Vande Hei and cosmonaut Pyotr Dubrov, who launched in April 2021, will now remain in space until March 2022. They will swap their original spacecraft seats home with a Russian director and actor filming a movie aboard the station next month. Vende Hei will become the new record holder for the longest U.S. spaceflight at 353 days, beating out Scott Kelly, who spent 340 days in space in 2015 and 2016.

Meanwhile at the ISS, two astronauts conducted a spacewalk to prepare for the installation of new solar arrays. Astronauts Akihiko Hoshide of the Japan Aerospace Exploration Agency and Thomas Pesquet of the European Space Agency installed a support bracket for the third array as part of an effort to ensure the station has enough power for a new generation of technology demonstrations and commercial activities.

NASA awarded five companies new contracts to work on lunar lander concepts for the agency’s Artemis program. Among the winning companies is SpaceX, which previously won a separate award to conduct a test flight of its Starship vehicle to the lunar surface, and Blue Origin, which is suing NASA over that same award.
