The Spacelab-Mir-1 (SLM-1) mission is the first docking of the Space Shuttle Atlantis (STS-71) with the Orbital Station Mir in June 1995. The SLM-1 "Greenhouse-2" experiment will utilize the Russian-Bulgarian-developed plant growth unit (Svet). "Greenhouse-2" will include two plantings (1) designed to test the capability of Svet to grow a crop of Superdwarf wheat from seed to seed, and (2) to provide green plant material for post-flight analysis. Protocols, procedures, and equipment for the experiment have been developed by the US-Russian science team. "Greenhouse-2" will also provide the first orbital test of a new Svet Instrumentation System (SIS) developed by Utah State University to provide near real time data on plant environmental parameters and gas-exchange rates. SIS supplements the Svet control and monitoring system with additional sensors for substrate moisture, air temperature, IR leaf temperature, light, oxygen, pressure, humidity, and carbon-dioxide. SIS provides the capability to monitor canopy transpiration and net assimilation of the plants growing in each vegetation unit (root zone) by enclosing the canopy in separate, retractable, ventilated leaf chambers. Six times during the seed-to-seed experiment, plant samples will be collected, leaf area measured, and plant parts fixed and/or dried for ground analysis. A second planting initiated 30 days before the arrival of a U.S. Shuttle [originally planned to be STS-71] is designed to provide green material at the vegetative development stage for ground analysis. [As this paper is being edited, the experiment has been delayed until after the arrival of STS-71.]
“和平号”-1航天飞机实验室（SLM-1）任务是1995年6月亚特兰蒂斯号航天飞机（STS-71）与和平号轨道空间站的首次对接。SLM-1“温室-2”实验将使用俄罗斯和保加利亚联合研制的植物生长单元（Svet）。“温室-2”将进行两次种植：（1）旨在测试Svet从种子到种子种植超级矮秆小麦作物的能力；（2）为飞行后分析提供绿色植物材料。该实验的方案、程序和设备由美俄科学团队制定。“温室-2”还将对犹他州立大学研制的新型Svet仪器系统（SIS）进行首次轨道测试，以提供植物环境参数和气体交换率的近实时数据。SIS通过增加用于监测基质湿度、空气温度、叶片红外温度、光照、氧气、压力、湿度和二氧化碳的传感器，对Svet控制和监测系统进行补充。SIS能够通过将植物冠层封闭在单独的、可伸缩的、通风的叶室中，监测每个植被单元（根区）中植物的冠层蒸腾作用和净同化作用。在从种子到种子的实验过程中，将六次采集植物样本，测量叶面积，并固定和/或干燥植物部分以供地面分析。在美国航天飞机[原计划为STS-71]抵达前30天开始的第二次种植，旨在在营养发育阶段提供绿色材料以供地面分析。[在本文编辑时，该实验已推迟到STS-71抵达之后。]
