“…Like our previous seed-to-seed growth of B. rapa in a wellventilated chamber on the Mir space station, the performance of B. rapa ʻAstroplantsʼ in the BPS on ISS was good. Plant dry weight, previously reported, was not statistically different in spacefl ight and ground control treatments (Morrow et al, 2004). Vegetative growth was vigorous and supported normal fl owering and seed initiation (Fig.…”

“…2002, the Biomass Production System (BPS) was transported to the International Space Station on Space Shuttle Atlantis. As part of a hardware verifi cation test (Morrow et al, 2004), plants of B. rapa ʻAstroplantsʼ were grown in one of the hardwareʼs four chambers. Although the goal of the verifi cation test was to put the hardware through its paces and determine performance, this was a unique opportunity to continue our general studies on the growth and development of plants in microgravity.…”

Although plants are envisioned to play a central role in life support systems for future long-duration space travel, plant growth in space has been problematic due to horticultural problems of nutrient delivery and gas resupply posed by the weightless environment. Iterative improvement in hardware designed for growth of plants on orbital platforms now provides confidence that plants can perform well in microgravity, enabling investigation of their nutritional characteristics. Plants of B. rapa (cv. Astroplants) were grown in the Biomass Production System on the International Space Station. Flowers were hand-pollinated and seeds were produced prior to harvest at 39 days after planting. The material was frozen or fixed while on orbit and subsequently analyzed in our laboratories. Gross measures of growth, leaf chlorophyll, starch and soluble carbohydrates confirmed comparable performance by the plants in spaceflight and ground control treatments. Analysis of glucosinolate production in the plant stems indicated that 3-butenylglucosinolate concentration was on average 75% greater in flight samples than in ground control samples. Similarly, the biochemical make-up of immature seeds produced during spaceflight and fixed or frozen while in orbit was significantly different from the ground controls. The immature seeds from the spaceflight treatment had higher concentrations of chlorophyll, starch, and soluble carbohydrates than the ground controls. Seed protein was significantly lower in the spaceflight material. Microscopy of immature seeds fixed in flight showed embryos to be at a range of developmental stages, while the ground control embryos had all reached the premature stage of development. Storage reserve deposition was more advanced in the ground control seeds. The spaceflight environment thus influences B. rapa metabolite production in ways that may affect flavor and nutritional quality of potential space produce.

“…(Monje et al, 2005). During the ISS Expedition 4 in 2002, the BPS was used to measure the photosynthetic canopy quantum yield (CQY), the conversion of absorbed radiation into gross CO 2 fixation, of wheat plant stands in microgravity using the CO 2 drawdown technique (Morrow et al, 2004(Morrow et al, , 2016Monje et al, 2005;Stutte et al, 2005). In that study, the canopy photosynthetic rates and CQY of 21-day-old wheat in microgravity did not differ from 1g controls at moderate light intensities (Stutte et al, 2005).…”

“…In contrast, the APH facility is a research, plant growth chamber that can grow plants under complete environmental control (i.e., spectral quality, light intensity, temperature, relative humidity, CO 2 and ethylene concentration) for life cycles as long as 135 days (Morrow et al, 2016). It incorporates a root module watering design that is similar to those developed for ADVASC and BPS: a substrate-based water delivery system that actively controls matric potential of the root zone (Morrow and Crabb, 2000;Link et al, 2003;Morrow et al, 2004).…”
