NASA has given the green light for Elon Musk’s SpaceX to launch the first unmanned test of its seven-seat Crew Dragon capsule on March 2 after passing a full day of reviews, bringing the space agency one step closer to replacing the retired Space Shuttle program after years of delays and ending its dependency on contracted Russian Soyuz rockets.

The test flight was originally scheduled for January, but was later delayed to complete hardware testing and other reviews. Per Space.com, NASA and SpaceX officials have now completed an in-depth review of the Crew Dragon’s capabilities called a flight readiness review, with NASA Commercial Crew Program manager Kathy Leuders telling reporters they needed to verify the craft “can safely go rendezvous and dock with the space station, and undock safely, and not pose a hazard to the International Space Station.”

Bezos: “I don’t think we’ll live on planets…I think we’ll live in giant O’Neal-style space colonies.”


  • Jeff Bezos, the founder of Amazon, gave a talk to a members-only event at the Yale Club in New York on Tuesday.
  • During the 30-minute lecture, Bezos said his private aerospace company, Blue Origin, would launch its first people into space aboard a New Shepard rocket in 2019.
  • Bezos also questioned the capabilities of a space tourism competitor, Virgin Galactic, and criticized the goal of Elon Musk and SpaceX to settle Mars with humans.
  • Ultimately, Bezos said he wants Blue Origin to enable a space-faring civilization where “a Mark Zuckerberg of space” and “1,000 Mozarts and 1,000 Einsteins” can flourish.
  • Bezos advised the crowd to hold a powerful, personal long-term vision, but to devote “the vast majority of your energy and attention” on shorter-term activities and those ranging up to 2- or 3-year timeframes.

Jeff Bezos may be the richest human on Earth, as the founder of Amazon, but his ultimate dreams reside within a relatively obscure company called Blue Origin.

In fact, as Bezos told the CEO of Business Insider’s parent company in April 2018, he liquidates $1 billion of stock a year to fund his private aerospace outfit.

“We’re likely to find hydrogen pretty much anywhere we go in the Solar System,” he said.

A spacecraft using conventional chemical rockets would take eight months to get to Mars during opposition. However, the VASIMR engine would make the journey in as little as 39 days.

Chang Diaz explained: “Remember, you are accelerating the first half of the journey – the other half you’re slowing, so you will reach Mars but not pass it. The top speed with respect to the Sun would be about 32 miles per second [or 51.5 km/s]. But that requires a nuclear power source to heat the plasma to the proper temperature.”
