Space X Launches Inmarsat-5

The launch of the Inmarsat-5 from Kennedy Space Center Launch Complex 39A (LC-39A). LC-39A saw many of the Apollo missions and eventually Apollo 11. After Apollo LC-39A was used for the Shuttle program and now the site is being used by Space X and after much modification Space X can support launches of both commercial and crew missions on SpaceX’s Falcon 9 and Falcon Heavy launch vehicles.

This is the fourth of the Inmarsat-5 spacecraft in the Global Xpress (GX) constellation. Inmarsat, the only operator of a global Ka-band network, created the GX platform to enable communities across the world to benefit from the emerging digital society.

Because of mission requirements there was no attempt to land the Falcon 9 rocket. is about 9-minutes into the video.

Space X Launch

Yesterday there was a issue with a first-state temperature sensor and the mission was put on hold with just 52 seconds left on the launch clock.

Today (01 May) Space X is launching a satellite from Pad 39-A at Kennedy Space Center. Coverage starts at 11:00 UTC/0700 ET.

The landing of the first stage should be covered in this webcast — good luck Space X!

Hosted Space X Launch Replay

Here is the SES-10 Hosted Webcast from of the historic flight by Space X. Being “out of town” most of the week, I barely got to see the launch. The hosted webcasts usually provide a good bit of information and this one is no exception:

The post yesterday never published. I had it in a queue but I made a mess of it and, well, nothing happened – my apologies.

The Dragon Departs

Here is a replay of the Space X Dragon cargo ship departing the International Space Station. The cargo ship was released at about 05:11 EDT / 09:11 UTC (if my time conversion is correct).

The Dragon will NOT burn up in the atmosphere as some ships do. The returning 5,400 + Lb / 2,450 + kg payload includes samples from a variety of scientific experiments.

The thrusters on Dragon will fire at around 10:00 EDT / 14:00 UTC commencing a deorbit burn which will send the ship into the Pacific Ocean 54 minutes later where it will be retrieved and returned by recovery teams.

As far as I know there will be no live coverage of the splashdown and recovery, however there could be video after the fact.

A Ride Around the Moon

Two round trip tickets.   The seats were filled according to Elon Musk.

So if Space X is going to do this in 2018, even late in 2018,  I would only guess they would be sending an unmanned vehicle and an “in-house” crew first.  I can’t really imagine that not being the case.

Here’s the Space X press announcement.

And a video about the announcment, this particular one from Bloomberg News:

SpaceX Launch Tomorrow

A Space X resupply mission, CRS-10 is scheduled for launch tomorrow.

Mission: CRS -10

 Description: science research, crew supplies and hardware to the orbiting laboratory in support of the Expedition 50 and 51 crew members

Rocket: Space X Falcon 9

Launch time:  14:39 UTC / 09:39 EST
Launch Site: Kennedy Space Center – Pad 39A

Space X will attempt to land the Falcon 9’s first stage on land for the first time. I would think that would be much easier than a floating barge!



SpaceX Launch/Landing Replay

Here is the SpaceX launch of the Iridium satellite replay. This is the entire Hosted Webcast; launch is 20 minutes into the video if you want to skip ahead.

Iridium Communications is reporting all 10 satellites were successfully deployed and will be in a testing phase for a few weeks.

On a sad note, this marks the end of Iridium flares, the beginning of the end anyway.  If you’ve never seen an Iridium flare you still can, but better probably to do so sooner rather than later.

Try either (or both) of the following links to get viewing information for Iridium flares or other visible satellites (like the ISS or Hubble):

The SpaceX Explosion

WHAT THE HECK WAS THAT??  I was out of town and following things along on my phone and this happens – it was just a static fire.

From this video it looks like the initial anomaly occurred at the upper stage near the vent.  I am waiting to hear what actually happened.  The video below from the BBC is excellent, but watch quick because there isn’t any lag to the incident.

So what could happen to cause this?  I can’t wait to find out.  I wouldn’t rule out the possibility the vented gases were ignited someplace external to the rocket and therefore not point to a issue with the rocket itself.  Sherlock Holmes I am not, but when I hear the news I did not expect the incident to start from the upper part of the rocket. WOW!

UPDATE SpaceX confirms the location of the initiating event (upper stages) and the incident occurred during fueling.

Cargo Ship Leaves The ISS – Replay

The SpaceX Dragon CRS-9 commercial cargo ship left the International Space Station a couple days ago on 26 August. The cargo ship was released from the Canadarm2 (really good views of the arm too) off Australia at 10:11 UTC.

The Dragon successfully splashed down in the Pacific around 482 km / 300 miles from the Baja of California with science and research cargo, and has been recovered.
