SpaceX to attempt launch of Bangabandhu satellite again

SpaceX will try again on Friday, May 11 (Saturday, May 12) to launch it’s first-ever "Block 5" Falcon 9 rocket to take the Bangabandhu satellite-1 in to its orbit in the space.

 

The Block 5 — the latest and final version of the workhorse Falcon 9 — was scheduled to launch the Bangabandhu Satellite-1 on Thursday, May 10 (Friday, May 11 in Bangladesh) from NASA's Kennedy Space Center (KSC) in Florida.

 

But an as-yet-undisclosed issue triggered an automatic abort just 58 seconds from liftoff, pushing the attempt back a day.

 

Launch is now targeted for 4:14 pm EDT (2014 GMT) on Friday (Early Saturday in Bangladesh) from KSC's historic Pad 39A, which once hosted liftoffs for NASA's space shuttle and Apollo programs.

 

The SpaceX also set a backup launch window opens on Saturday, May 12 at 4:15 pm EDT or 20:15 UTC.

 

Bangabandhu Satellite-1 will be deployed into a geostationary transfer orbit (GTO) approximately 33 minutes after launch.

 

You can watch it live at Space.com, courtesy of SpaceX, or directly via SpaceX's website, beginning about 20 minutes before liftoff. The action will include a landing attempt by the two-stage rocket's first stage on a ship at sea.

The Block 5 was upgraded to meet NASA's crew-carrying requirements; SpaceX will use the rocket to launch agency astronauts toward the International Space Station (ISS). SpaceX holds a multibillion-dollar deal with NASA to perform such taxi services, as does aerospace giant Boeing.

 

The Block 5 also features a series of improvements that should significantly boost its reusability. Whereas the first stages of previous Falcon 9 iterations have launched a maximum of two times, the Block 5 first stage will be capable of 10 orbital flights with just inspections between liftoff and landing, and perhaps 100 or more with some refurbishment involved, SpaceX founder and CEO Elon Musk said during a teleconference with reporters yesterday.

 

Musk said that the Block 5 is designed to be the most reliable rocket ever built, and that he's confident in the vehicle's long-term prospects. But the vehicle's maiden flight is causing him some anxiety, he added.

 

"You know, it could be a thousand things that go right on this rocket, and one that goes wrong, and a passing grade for rockets — the reason that it's so hard to make an orbital rocket work — is that your passing grade is 100 percent," Musk said during yesterday's telecon. "And you can't fully and properly test an orbital rocket until it launches, because you can't recreate those exact conditions on Earth. Everything's sort of a proxy for traveling hypersonically through a vacuum. Yeah. Man. Anyway, I'm stressed."

 

He added this last bit with a chuckle, then told the reporters that "any good wishes would be appreciated."

 

Bangabandhu-1 will be Bangladesh's first satellite. The spacecraft was built by French company Thales Alenia Space, and the government of Bangladesh will use it to provide a variety of communications services to its citizens.
