SpaceX invited a few reporters into its Hawthorne, California, headquarters on Monday for a close-up look at a new spaceship and spacesuit for NASA astronauts.

The aerospace company, founded by tech mogul Elon Musk, built its Crew Dragon hardware as part of the agency's Commercial Crew Program. Boeing also designed a new space capsule for NASA called the CST-100 Starliner.

NASA launched program in 2010 to replace its (now retired) space-shuttle fleet with privately developed American spacecraft — and stop paying Russia more and more money to fly astronauts to the International Space Station.

Crewed test launches of each spaceship are set to begin in 2019. But SpaceX is poised to send the commercial astronauts into space first, given that Boeing must fix leaky fuel valves on the CST-100 Starliner.

Some who climbed aboard SpaceX's mockups shared photos and videos of the event on Twitter and Instagram.

Here's a sample of some of the best footage and pictures, and what reporters said it was like inside:
