Light Microscopy Modle, LMM, Ground Unit Testing, GU. Control Systems Engineer using a small magnet to maneuver a 1mm metal stir-bar into a colloid sample fluid-filled capillary. The capillary tubes of sample fluid will be filled and sealed. The sample fluid supplied by a Principal Investigator typically contains some hazardous/toxic chemicals that she must ensure will not leak and put the astronauts at risk. On-orbit on the LMM, ‘insitu mixing’ is used, which uses electromagnetic inductors to stimulate the metal stir-bar to mix the fluid within the sealed capillary.

The Atlas V rocket that will launch Boeing’s CST-100 Starliner spacecraft on the company’s uncrewed Orbital Flight Test for NASA’s Commercial Crew Program is coming together inside a United Launch Alliance facility in Decatur, Alabama. The flight test is intended to prove the design of the integrated space system prior to the Crew Flight Test. These events are part of NASA’s required certification process as the company works to regularly fly astronauts to and from the International Space Station. Boeing's Starliner will launch on the United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

Aerospace Engineer, Daniel Senai, inspects the Solar Calibration Assembly (SCA) Life Test Unit mechanism for the Ocean Color Instrument (OCI) to ensure it is ready for the next level of assembly. OCI is a highly advanced optical spectrometer that will be used to measure properties of light over portions of the electromagnetic spectrum. It will enable continuous measurement of light at finer wavelength resolution than previous NASA satellite sensors, extending key system ocean color data records for climate studies. OCI is PACE's (Plankton, Aerosol, Cloud, ocean Ecosystem) primary sensor built at Goddard Space Flight Center in Greenbelt, MD.
