On Tuesday, SpaceX halted the planned launch minutes before liftoff due to a technical issue, though it said afterward the rocket and payload "remain healthy".
Meanwhile, Blue Origin is now targeting a Friday launch for its resuable New Shepard rocket and space capsule.
Separately, SpaceX's launch of a much-delayed navigation satellite for the USA military was halted on Tuesday, postponing for at least a day the space transportation company's first designated national security mission for the United States. SpaceX said its rocket threw an abort alert due to a sensor issue, while Blue Origin explained that a "ground infrastructure issue" was to blame for its own delay.
SpaceX will be launching the spacecraft, also known as Satellite Vehicle 01, from a new Falcon 9 rocket.
Lastly, United Launch Alliance has scheduled its Delta Heavy rocket to lift off from Vandenberg Air Force Base on California's central coast at 8:57 pm EST.

He also said Arab and Western delegations had begun visiting Syria to prepare for the reopening of diplomatic missions. Syria's long-running war has killed hundreds of thousands of people and forced millions from their homes.
"This marks the first competitive bid launch in over 10 years", said Col. Robert Bongiovi, director of the Launch Enterprise Systems Directorate at the Air Force's Space and Missile Systems Center in Los Angeles.
Tuesday was set to be a day which had rocket enthusiasts glued to their screens, with four commercial space missions planned for launches in the United States - but three have been postponed until tomorrow because of strong winds.
"Standing down from today's launch attempt of GPS III SV01 to further evaluate out of family reading on first stage sensors; will confirm a new launch date once complete", they said in a Twitter update. The capsule will be uncrewed and will be taking a NASA-sponsored payload into space. All the technical issues were all overcome, and then rockets were launched. 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.
But a third rocket Arianespace's Soyuz was still slated to send up a military satellite for France.
After those two high-profile launches, two other missions will take off later on Tuesday.
