Astronaut Scott Kelly initiated VEG-01 B, the second crop of lettuce, on July, 8, 2015, and both Kelly and Astronaut Kjell Lindgren cared for the plants. The crop grew for 33 days. VEG-01 B included one set of six plant pillows planted with red romaine lettuce seeds. On Aug. 10, 2015, the crew harvested and consumed leaves from each plant. This was the first crop grown and consumed in NASA hardware. They harvested the rest of the plant tissue and froze it in the stations Minus Eighty-Degree Laboratory Freezer for ISS (MELFI) for return to Earth for further study including microbial analysis, antioxidant capacity, mineral analysis and anthocyanin concentration.

Spaceward Bound event in the Mojave Deser , CA (an outreach exercise) with Dr Chris McKay and Ames Education department personnel Brian Day, Barbara Bazar and a accompaning (learning for the the classroom) team of teachers will be studying side-by-side with NASA scientists who search for life in extreme environments, closely approximating what they expect to find on other planets. Why the Mojave -- an inhospitable, sun-drenched spot in the California Desert This natural setting presents scientists with opportunities to study environments that are analogous to what explorers will find on the Moon and Mars. Teachers and scientists will perform scientific fieldwork in lunar geology, Mars astrobiology, Mars geology, and issues of temperature and solar inundation and radiation. for additional information and Outreach projects see http //quest.arc.nasa.gov/

Pieces of the Huygens probe internal insulating foam await inspection after removal from the probe in the Payload Hazardous Servicing Facility (PHSF) at KSC. The spacecraft was returned to the PHSF after damage to thermal insulation was discovered inside Huygens from an abnormally high flow of conditioned air. Internal inspection, insulation repair and a cleaning of the probe were required. Mission managers are targeting a mid-October launch date after Cassini returns to the pad and is once again placed atop its Titan IVB expendable launch vehicle at Launch Pad 40 at Cape Canaveral Air Station

KENNEDY SPACE CENTER, FLA. -- The STS-91 crew participate in the Crew Equipment Interface Test (CEIT) for their upcoming Space Shuttle mission at the SPACEHAB Payload Processing Facility in Cape Canaveral. The CEIT gives astronauts an opportunity to get a hands-on look at the payloads with which they will be working on-orbit. STS-91 will be the ninth and final scheduled Mir docking and will include a single module of SPACEHAB, used mainly as a large pressurized cargo container for science, logistical equipment and supplies to be exchanged between the orbiter Discovery and the Russian Space Station Mir. The nearly 10-day flight of STS-91 also is scheduled to include the return of the last astronaut to live and work aboard the Russian orbiting outpost, Mission Specialist Andy Thomas, Ph.D. Liftoff of Discovery and its six-member crew is targeted for May 28, 1998, at 8:05 p.m. EDT from Launch Pad 39A. Seen here are STS-91 Mission Specialist Valery Ryumin with the Russian Space Agency and
