9．China's newest space laboratory，TiangongⅡ，will be sent up into the air from the Jiuquan Satellite Launch Center in Northwest China．It will provide more comfortable digs for astronauts living aboard．
Zhu Zongpeng，chief designer of TiangongⅡsaid designers aimed to create an astronaut-friendly environment in every regard when they refitted the space lab that was developed based on TiangongⅠ．
"A number of particulars were taken into account，including the sound，lighting，inner decorations as well as support equipment．For instance，the carpet in Tiangong I was replaced with floorboards．We fixed a foldable，multifunctional table that can be used for dining and experiments．The light is softer and can be adjusted．Each astronaut has a bed lamp．We also equipped the astronauts with Bluetooth headsets and Bluetooth speakers．"Zhu added．
The TiangongⅡconsists of two cabins（艙）with separate functions-the experiment cabin is sealed and acts as the astronauts'living quarters，while the resource cabin contains solar panels（太陽電池板），storage batteries，engines，etc．
The lab has about 15 square meters for astronauts to live and work，including a separate sleep section and waste storage area．The equipment in the spacecraft ensures its inner sound under 50 decibels（分貝）．The temperature within the experiment cabin is kept between 22℃and 24℃and the humidity（濕度）between 45 and 55 percent．
In addition，TiangongⅡhas an air detector（空氣探測器），and it can be used to check and deal with more than 20 dangerous gases．Also，designers placed exercise equipment in the space lab to help astronauts keep healthy and its communication systems also allow astronauts to receive and reply to emails and make calls to family and friends．
