A great piece from Halma plc, parent company of Labsphere.
Looking for signs of extra-terrestrial life has long been a plot for many blockbuster movies. But despite dozens of missions to Mars there has been no proof that life, past or present, exists beyond Earth. Recent research, however, has concluded that ancient Mars used to be significantly wetter and warmer than we first thought and could even now be a home for microbial life. One of our Halma companies – Labsphere – has played a vital role in enabling the latest search for life on Mars.
