Nauka docks, but bizarre engine firings delay OFT-2 launch
Coalition Member in the News – Boeing
Spacepolicyonline.com (7/30): Eight days after launching from the Baikonur Cosmodrome in Kazakhstan, Russia’s Nauka Multipurpose Laboratory Module docked early Thursday at a port on the ISS Russian segment cleared earlier by the departure Monday of the 20-year-old Pirs docking module and airlock. Suddenly after docking, Nauka’s thrusters began to fire with enough force to change the attitude of the entire ISS by 45 degrees. Though the ISS’s U.S. gyroscope attitude control system was overwhelmed, thrusters on the Russian segments Zvezda module and docked Progress 78 cargo capsule fired to correct the attitude. While an investigation into the incident unfolds, NASA and Boeing have postponed plans for today’s launch of Orbital Flight Test-2 (OFT-2), an uncrewed test flight of the company’s CST-100 Starliner to conduct an autonomous docking with the ISS’s U.S. segment.

Saturn will soon put on its best show of the year. Here’s where and how to see it
NPR (7/29): Saturn is about to put on its best and brightest show, looking spiffier than at any time during the year – a performance that will be followed a few weeks later by Jupiter.

Scientists find two huge red rocks with ‘complex organic matter’ in the asteroid belt that shouldn’t be there
The Independent (7/29): A Japanese-led research effort has identified two unexpected objects at home in the main asteroid belt between Mars and Jupiter. The objects named Pompeja and Justitia, respectively 70 and 35 miles across and with an unusual reddish tint, appear to have long ago established their homes in the belt. They may be organically rich and an indication that their origins from the early days of the solar system were well beyond Neptune but then they migrated closer.
