iss071e170979 (June 6, 2024) -- Boeing's Starliner spacecraft is pictured approaching the International Space Station for an autonomous docking on June 6, 2024 as the spacecraft and orbiting laboratory soared 257 miles above the South Pacific Ocean. Starliner launched on June 5, with NASA astronauts Butch Wilmore and Suni Williams aboard, as part of NASA's Boeing Crew Flight Test. This first crewed flight of Starliner aims to certify the spacecraft for rotational missions to the space station.

Off the rear of the USS Anchorage, the Orion test article is pulled in by a winch line at the rear of the USS Anchorage’s well deck that brings the capsule into the ship, along with four manned LLAMAs (Line Load Attenuation Mechanism Assembly) that control the capsule’s side-to-side movement and a tending line attached to a rigid hull inflatable boat for controlling Orion’s movement behind the ship. The Underway Recovery Test 6 (URT-6) is spearheaded by Kennedy Space Center's NASA Recovery Team. In partnership with the U.S. Navy, the testing will provide important data that is being used to improve recovery procedures and hardware ahead of Orion's next flight, Exploration Mission-1, when it splashes down in the Pacific Ocean.

NASA Recovery Director Melissa Jones watches part of Underway Recovery Test 6, from the flight deck of the USS Anchorage. During this portion, the Orion test article is intentionally subjected to an increased sea state as the NASA Recovery Team works hard to keep control of the spacecraft. The testing with Kennedy Space Center's NASA Recovery Team and the U.S. Navy will provide important data that is being used to improve recovery procedures and hardware ahead of Orion's next flight, Exploration Mission-1, when it splashes down in the Pacific Ocean.

The uncrewed Orbital Flight Test will be Starliner’s maiden mission to the International Space Station for NASA's Commercial Crew Program. The mission, currently targeted for a 6:36 a.m. EST launch on Dec. 20, will serve as an end-to-end test of the system's capabilities. Photo Credit: (NASA/Joel Kowsky)

VANDENBERG AFB, CALIF. - In the spacecraft processing facility on North Vandenberg Air Force Base, the Gravity Probe B experiment sits on an assembly and test stand where it has been subject to various prelaunch testing. The Gravity Probe B will launch a payload of four gyroscopes into low-Earth polar orbit to test two extraordinary predictions of Albert Einstein’s general theory of relativity: the geodetic effect (how space and time are warped by the presence of the Earth) and frame dragging (how Earth’s rotation drags space and time around with it). Once in orbit, for 18 months each gyroscope’s spin axis will be monitored as it travels through local spacetime, observing and measuring these effects. The experiment was developed by Stanford University, Lockheed Martin and NASA’s Marshall Space Flight Center. The targeted launch date is Dec. 6, 2003.
