In September, the European Space Agency will begin the formal competition for its second "large" satellite mission, L2. The space-based gravitational-wave observatory eLISA (evolved Laser Interferometer Satellite Antenna) will be one of the contendors. There is a web site where members of the public can register their support for eLISA. This takes just a minute, and is an easy way for you to support future efforts to detect and study gravitational waves and gravitational-wave sources!
