NASA seeks proposals for commercial ISS modules
SpaceNews.com (6/24): Last Friday, NASA issued a call for proposals from the private sector to add a commercial module to the International Space Station (ISS), part of the agency’s latest efforts to spur low Earth orbit economic growth. If the strategy works, the module would join the Station at a Harmony module docking port. NASA plans to enter into one or more concept development agreements and may fund early design work. The commercial module addition is planned for no later than September 2024. An additional solicitation is anticipated this summer for possible low Earth orbit commercial free flyer destinations. The preparations are part of a plan by NASA to transition its oversight of human exploration from low Earth orbit to deep space, while becoming one of many customers of commercial low Earth orbit services.

NanoRacks, Zero G Kitchen, and DoubleTree by Hilton announce cookies in space program: The first-ever space oven and microgravity baking experiment
Nanoracks (6/24): NanoRacks, approached by Zero G Kitchen about a year ago, has developed  the first ever space oven, a device that will permit astronauts to prepare recipes in space rather than warm up meals prepared on Earth. Zero G also approached DoubleTree by Hilton with the idea of a baking experiment using one of the company’s chocolate chip cookies. The oven and cookie dough are to launch to the International Space Station (ISS) later this year.
