SpaceX reveals new launch date for 5th attempt at Falcon Heavy mission

SpaceX has revealed a new target launch date for a mission that will see its triple-booster Falcon Heavy rocket carry an experimental space plane to orbit for the U.S. Space Force.

The private spaceflight company has announced that it’s now targeting the launch for no earlier than Thursday, December 28.

Last week, SpaceX stood down from launching the rocket four times, on consecutive days. Reasons included poor weather conditions at the launch site at the Kennedy Space Center in Florida, and an unspecified “side issue” on the ground. At no point has there been any suggestion of a problem affecting the rocket itself, which will be launching for only the ninth time in its five-year history when the mission finally gets underway.

With the Falcon Heavy packing 5.5 million pounds of thrust at launch, the liftoff promises to be a real spectacle for anyone viewing it in person or watching the live stream.

But while the Falcon Heavy is three times more powerful than SpaceX’s workhorse Falcon 9 rocket, it’s considerably less powerful than the company’s next-generation Starship vehicle (comprising the first-stage Super Heavy rocket and second-stage Starship spacecraft), which failed to reach orbit on its first two test flights, the most recent of which took place last month.

The Falcon Heavy will deploy the Space Force’s X-37B space plane on what will be its seventh mission since its first one in 2010. The uncrewed space shuttle-like vehicle will conduct various tests while in orbit, including flying in “new orbital regimes, experimenting with future space domain awareness technologies, and investigating the radiation effects on materials provided by NASA,” according to the Space Force.

Digital Trends has an article featuring everything you need to know to watch the mission, which will include not only the launch, but also the return to Earth of the Falcon Heavy’s two side boosters, which will be used again.

SpaceX’s delayed Polaris Dawn mission to launch tonight

The historic SpaceX Polaris Dawn mission, which includes the first-ever commercial spacewalk, will launch tonight from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Four private astronauts, three of whom have never been to space before, will travel to the highest altitude yet reached by a SpaceX Crew Dragon and perform experiments into human health in space.

The mission has been repeatedly delayed because of a confluence of issues including weather and the FAA temporarily grounding the Falcon 9 rocket following the failure of a booster during landing. But now the go-ahead has been given, and the company is readying for a launch in a few hours' time. Launch is scheduled for 3:38 a.m. ET on September 10. If necessary, there are also two other possible launch times at 5:23 a.m. ET and 7:09 a.m. ET., and more opportunities on Wednesday.

SpaceX’s Polaris Dawn mission faces further delay after FAA grounds Falcon 9

SpaceX’s workhorse Falcon 9 rocket has been grounded by the Federal Aviation Administration (FAA) after one of the boosters toppled over and exploded shortly after landing at the end of a mission on Wednesday.

The FAA said it will carry out an inquiry into the incident, adding that the Falcon 9 shouldn’t fly again until it’s complete.

SpaceX calls off today’s launch of Polaris Dawn

SpaceX has called off the launch of the highly anticipated Polaris Dawn mission for the second day in a row, but this time it has not set a new schedule.

In a message posted on social media on Tuesday evening about five hours before a Falcon 9 rocket carrying four passengers was due to lift off from the Kennedy Space Center in Florida, the spaceflight company said it had made the decision due to a weather forecast that suggested there will be unfavourable conditions off the coast of Florida in five days’ time, when the Crew Dragon spacecraft was due to splash down. It added that it will continue to assess the weather situation before deciding on a new launch schedule.
