2 astronauts performing spacewalk Wednesday morning: Watch live
Space.com (3/23): NASA and European Space Agency (ESA) astronauts Raja Chari and Matthias Maurer are to embark on a planned 6 1/2-hour spacewalk outside the International Space Station (ISS) on Wednesday just before 9 a.m. EDT. The primary task is the installation of refurbished hoses on a radiator beam valve module. The module helps to provide thermal control for the ISS through the flow of ammonia coolant within outstretched radiator panels. The spacewalk is Chari’s second within the past eight days and Maurer’s first ever. NASA is airing the activities on NASA TV and streaming at www.nasa.gov/nasalive.

Legally, Russia can’t just take its Space Station and go home
Ars Technica (3/22): Since 1998 and the start of its assembly, the International Space Station (ISS) has operated under an Intergovernmental Agreement (IGA) that governs obligations and operations among the partner nations. Like the orbital lab itself, the IGA is more than a sum of its partners, explains Joanne Irene Gabrynowicz, an emeritus professor of law at the University of Mississippi and an expert on the IGA. Historically, Russia because of its Soviet predecessor, can justifiably claim itself as the first nation in space and likely very much wants to preserve its reputation as a global space power. Stepping from the ISS partnership, as the head of Russia’s space agency, Roscosmos, has threatened, could actually end Russia’s civil space program. “The bottom line is this: There are sound technical, legal, and political reasons for Putin’s Russia to remain involved in the International Space Station for as long as the West will have them,” according to Ars Technica’s assessment.

Mars helicopter Ingenuity soars on 22nd Red Planet flight
Space.com (3/22): NASA’s Ingenuity Mars helicopter took flight for a 22nd time on Sunday, staying aloft for 101.4 seconds and reaching an altitude of 33 feet. Currently Ingenuity’s reconnaissance is helping Earth-based mission teams choose the best route for NASA’s Perseverance Mars to transit the floor of Jezero crater on Mars to a companion ancient stream delta. There, the rover will gather additional samples of the Martian surface for eventual return to Earth so they can be studied for possible evidence of past biological activity.

The fruition of a dream
Stwnewspress.com of Stillwater Oklahoma (3/15): Once known as the “final frontier,” space is actually the “future frontier,” writes Brenda Rolls, president and CEO of Frontier Electronic Systems (FES). FES is a small Oklahoma high tech company that provides electronics for aerospace endeavors including the International Space Station (ISS), NASA’s Space Launch System (SLS) and Orion crew module, and the CST-100 Starliner. “Oklahoma is not typically thought of as a ‘space’ state, but we are,” writes Rolls, whose heritage includes Native American. “Together with hundreds of small businesses like mine across 48 states, we are working to manufacture the parts and technology to take the SLS and America’s future in space, from a possibility to a reality.”
