For the second time in a week, NASA scrubbed the launch of the Space Launch System designed to return Americans to the moon. First conceived in 2010, and initially scheduled to have its first test flight in 2017, the rocket is now scheduled to take off no earlier than late September, and possibly much later. NASA, for its part, is hoping Americans will overlook a decade of expensive failure and pray for the best.
They shouldn't. The SLS's path to the launch pad should never have happened. Conceived as a means to maintain US aerospace employment, and based in part on older rocket designs and parts, the project has siphoned funds and energy.
Some proponents argue that the SLS launch marks the beginning of a 'renaissance' for the US space program. It's the first mission of NASA's Artemis Moon Mission, designed to land Americans on the moon mid-decade and eventually lead to a permanent lunar base. All of that will require a working and successful SLS, and this mission - Artemis I - would stress test its capabilities and send Orion, a vehicle that will eventually hold astronauts, on a trip around the moon. It sounds groundbreaking, but the reality is that private-sector space companies have been pushing boundaries for more than a decade while the SLS lingered through delays and blown budgets.
The last humans to visit the moon's surface arrived via the Apollo 17 mission in 1972. Congress canceled an additional three missions due to cost, safety and waning public and policy-maker interest. Instead, NASA pursued the space shuttle, the International Space Station and a rich robotic exploration program of the Earth and beyond.
Then, in the 2000s the George W. Bush administration chose to invest in Constellation, a hugely
