Zacks Investment Ideas feature highlights: SpaceX's and Tesla

For Immediate Release Chicago, IL – September 17, 2026 – Today, Zacks Investment Ideas features SpaceX's SPCX and Tesla TSLA Starship Test: SpaceX's Quest for the Holy Grail of Rocketry Starship: The Most Ambitious Spacecraft Ever Built SpaceX's Starship is by far the most ambitious spacecraft ever conceived. Starship is the tallest, heaviest, and most powerful rocket built in history. For context, Starship's thrust is more than double the 7.6 million pounds of thrust produced by NASA's now-retired Saturn V. The latest Starship iterations allow a payload capacity of 200 metric tons (Saturn V had a payload capacity of 240 metric tons). However, Starship is unique beyond its size and power.
