Boeing would conduct the first orbital test of its CST-100 Starliner spacecraft in June 2018 in the latest Commercial Crew Program schedule unveiled by NASA this week.

The automated flight test to the International Space Station (ISS) would be followed by a crewed flight test to ISS in August 2018. If all goes well, CST-100 Starliner would be certified by NASA to carry crews to the orbiting outpost in October 2018.

Before it can begin flights, Boeing has a number of key tests. The most spectacular one will be an on-pad abort test scheduled for February 2018.

NASA officials said this week that Boeing’s schedule is aggressive, meaning that additional delays are possible in a schedule that repeatedly moved to the right.

The current schedule is below.
