In space sciences coming up are new manned Moon missions followed hopefully by some Mars missions. Also LISA is a huge interferometer that is planned to be deployed in orbit by ESA around 2035. Different size interferometers can measure different wavelengths of gravitational waves. LIGO (the interferometer observatory already in action measuring black hole collisions) has arms 4km long and can measure wavelengths in the range of 7Khz-30hz. LISA will have arms 2.5 million km long in orbit around the sun and is expected to be able to measure much much smaller waves.
