During the tests with the space shuttle prototype Enterprise in 1977 with a release from atop the NASA 747, it was validated the shuttle could land unpowered. The center was a key part of the Space Shuttle Program including the Approach and Landing Tests. That nine-day mission included the capture of the inoperable Intelsat VI communications satellite and replacement of its rocket motor. NASA Armstrong was part of Endeavour’s history, including its first landing from space on STS-49 more than 30 years ago on May 16, 1992. It was built as a replacement for space shuttle Challenger, which had a fatal incident after launch on Jan. Today, Artemis focuses on returning humans to the Moon, establishing a long-term presence in deep space, eventually sending astronauts to Mars.Įndeavour was the fifth orbiter built and it first arrived at NASA’s Kennedy Space Center in Florida on May 7, 1991, atop the NASA 747. The shuttle Endeavour brought the first parts of the International Space Station to space and completed 25 missions. Also on the route were the Los Angeles Memorial Coliseum, NASA’s Ames Research Center, NASA’s Jet Propulsion Laboratory in Pasadena, and the Santa Monica Pier. Included on the space shuttle’s flight path were many California landmarks such as the California State Capitol Building, Disneyland, Dodger Stadium, the Getty Center, the Golden Gate Bridge, and the Hollywood sign. Those aircraft were flown by NASA Armstrong pilots, while center photographers and videographers documented the orbiter’s final journey. On its final flight to the California Science Center, Endeavour was escorted by a combination of F/A-18s and an F-15 from NASA’s Armstrong Flight Research Center in Edwards, Calif. Space shuttle Endeavour and its host NASA 747 Shuttle Carrier Aircraft fly by the Golden Gate Bridge in 2012 on its way to the Los Angeles International Airport and an overland journey to the California Science Center. Today, all eyes are on Artemis I, the upcoming first launch of NASA’s mega Moon rocket, the Space Launch System, and the Orion spacecraft, as NASA builds a long-term presence at the Moon as part of Artemis. We assess the impact on performance of the different manufacturing and alignment errors.Ten years ago, people all over California watched the skies in hopes of catching a glimpse of space shuttle Endeavour as the NASA 747 Shuttle Carrier Aircraft as it ferried Endeavour to Los Angeles on Sept. The CMC mask was manufactured at JPL’s Microdevices Laboratory and we include surface profile characterization measurement. In particular, the model verification includes measured sags of the manufactured PIAA mirrors by NuTek. We use empirical measurements from the vacuum testbed to verify the instrument model and its performance including line-of-sight errors, instrument alignment, and fabricated components. In this work, we review the theoretical performance of the PIAACMC instrument designed to meet a 1e-9 raw contrast goal in 10% broadband light in a region from 2-8 L/D both before and after the wavefront control loop. PIAACMC has been recently implemented for LUVOIR-A and is currently being tested in vacuum at JPL’s High-Contrast Imaging Testbed (HCIT). PIAACMC designs are compatible with large, on-axis, segmented apertures such as the Large UV / Optical/ Infrared A (LUVOIR-A) concept currently being considered by the decadal survey review which would greatly enhance the possibility to achieve statistically significant scientific yields and signal quality for direct imaging exoplanet surveys. Model Validation of Phase-Induced Amplitude Apodization Complex Mask Coronagraph for LUVOIR-A in Vacuum The Phase-Induced Amplitude Apodization Complex Mask Coronagraph (PIAACMC) is a coronagraph architecture for the next generation of large space telescopes optimized for habitable exoplanet imaging that can achieve attractive theoretical performance with high throughput at small inner working angles (IWA). ![]()
