SpaceX has competition in the form of space startup Rocket Lab, as the firm plans an ambitious Venus mission, develops a rocket that can send humans into space and also launch mega-constellation satellites into orbit. This move comes off the back of a $4.1 billion listing on the Nasdaq exchange that has allowed the California firm to move away from small-scale satellite launches. Founder, CEO and CTO of Rocket Lab, Peter Beck, told MailOnline the goal is to bring down the cost of getting small satellites into space, and make it cheaper for universities to send experiments to the moon, Mars and Venus.
