A record-breaking four different rockets will all launch today, but each rocket is being launched by a different company, reports Bloomberg.
Meanwhile, Blue Origin is now targeting a Friday launch for its resuable New Shepard rocket and space capsule.
There was not enough time left in the window to fix the problem, so launch was delayed to 9:07 a.m. EST Wednesday. It was initially delayed because of "upper level winds", according to the Space X Twitter account, before eventually being cancelled for the day because of an "out of family reading on first stage sensors". Weather forced a cancelation of what would be the company's tenth New Shephard mission, which "is dedicated to bringing nine NASA-sponsored research and technology payloads into space through NASA's Flight Opportunities program".
"Still working through ground infrastructure issues and monitoring incoming weather in West Texas", Blue Origin representatives wrote on Twitter.
"I attended my first launch here at Kennedy Space Center 15 years ago and the most important thing is that we got that rocket up safely and securely and it achieves its mission", Pence said.More news: Saturn's Rings Are Disappearing According to NASA

The company said that due to mission requirements, they will not attempt to land Falcon 9's rocket after launch. The long-awaited flight already had slipped to almost the end of the available launch window because of high upper level winds when the issue cropped up.
The satellite, nicknamed "Vespucci", is the first in a series of 10 third generation satellites ordered by the Air Force with three times better accuracy, eight times improved anti-jamming capabilities, 25 percent longer spacecraft lifespan and the capability to broadcast signals compatible with other worldwide global navigation systems, including Europe's Galileo.
The launch is scheduled to happen from Space Launch Complex 40 at the Cape Canaveral Air Force Station in Florida.
