SpaceX set to launch Wednesday morning

Paz satellite will be used for military and civilian purposes.

SpaceX had initially planned for the launch to take place last Saturday, before delaying it due to the need for more inspections.

In a tweet on Tuesday, SpaceX said the rocket is vertical and the weather is 90 percent favorable for launch.

Zipping along at 43,177 miles per hour, Elon Musk's cherry-red Tesla Roadster has exceeded its 36,000-mile warranty - 720 times, in fact. It has landed these boosters on both land and at sea. Musk has also built a huge drone ship with metal arms to catch and reuse the rocket fairings.

SpaceX often tries to reuse key rocket parts as a means of cutting costs.

SpaceX has previously recovered a nose cone previous year during a launch but it will now attempt to capture the fairing using the net boat called Mr. Steven. SpaceX didn't publicly speak about the Starlink prototypes, although it revealed their presence on the Falcon 9 rockets in Federal Communications Commission filings.

SpaceX successfully launched the first Falcon Heavy, touted as "the world's most powerful rocket", into space on February 6.

SpaceX plans to launch another Falcon 9 rocket (pictured) from Vandenberg Air Force Base in Southern California on Wednesday.

Launching things into space is cost-prohibitive, to say the least.

How do we know all this?

For example, the total cost of a Falcon 9 launch is estimated to be about $61 million. The launch's primary mission is to deliver an observational satellite, called PAZ, for the Spanish government. Both of the side boosters landed successfully (and almost simultaneously) at nearby Cape Canaveral Air Force Station less than 10 minutes after blasting off from KSC.

The payload fairings are clam shell-like nose cone halves that protect the craft's payload.

The next SpaceX Falcon 9 launch is scheduled for February 21, barring any setbacks (it was originally scheduled for February 18).

FCC Chairman Ajit Pai proposed the approval of an application by SpaceX to provide broadband services using satellites in the United States and worldwide. The rocket will send first batch of two Starlink broadband satellites to test out the technology needed to beam down internet from the space.
