SpaceX is considering sabotage as cause of Falcon 9 explosion


Dear readers and followers,

As SpaceX’s investigation of a Falcon 9 rocket explosion on September 1st drags into its second month, rumors are flying that this may have been more than a random technical failure. According to a Washington Postreport, SpaceX is considering the possibility of sabotage.





In a Holmesian twist to the investigation of the sudden fireball that eviscerated a Falcon 9 rocket, a $95 million internet satellite, and a chunk of Cape Canaveral’s launch pad 40, a SpaceX employee recently requested rooftop access to a building owned by competing rocket consortium United Launch Alliance. As industry officials who spoke on condition of anonymity told the Washington Post, SpaceX was following up on “something suspicious” it had seen while reviewing video footage of the rocket explosion—a weird shadow and a white spot on the roof of the ULA building, which sits about a mile from the launch pad.

According to the Washington Post’s unnamed experts, SpaceX was denied access to the rooftop, which was instead investigated by Air Force officials who found no evidence of a connection to the September 1st explosion. 

SpaceX’s official line—that it’s simply trying to leave no stone unturned—may well be true. But that hasn’t stopped the internet from offering up its own conspiracy theories, including that maybe a guy with a rifle shot the rocket from a mile away. (After all, Musk did say his company is trying to figure out the source of a “quieter bang sound” a few seconds before the fireball!)



Then again, as Elon Musk noted during his Martian colonization speechlast week, SpaceX has already investigated all obvious possibilities. “What remains are the less probable answers,” he said.

A ULA spokesperson responded to Gizmodo’s request for comment in an email, stating that “ULA cooperated with the Air Force’s 45th Space Wing, and nothing associated with the SpaceX accident was found.”

Live streaming of Orion space launch

Dear readers and followers,

Earlier this morning, the United Launch Alliance tower used to prepare the Orion spacecraft for liftoff was moved away. You can watch the rollback below: 



Mobile Service Tower rollback from NASA Orion Spacecraft on Vimeo.


The United Launch Alliance Delta IV Heavy rocket with NASA’s Orion spacecraft mounted atop is seen here at Cape Canaveral Air Force Station's Space Launch Complex 37, Florida. 

Update in pictures there:








The second stage issue and boat in the range. Delay possible, but 2 hours launch window gives flexibility. This delay is not due to technical or weather problems for launch. It's on a hold due to a boat in range of launch







- New launch time set for 7:17 a.m EST, but it has been delayed again because of wind, as shown in the picture below which show the 1-minute peak wind speed measured at 230-ft above pad 41.

7: 46 am ESTNew T-0 of 7:55 am EST has been decided




7: 43 am EST: Hold hold hold again ... launch delayed

- 8: 16 am EST: New T-0 8:26 am EST, the launch will be for today


- 8: 24 am EST: HOLD AGAIN . Launch team reports the rocket's fill and drain valve did not close.


- 8:39 am EST: The technical problem seems to come from the valves. Fill-&-drain valves on 3 core boosters will be cycled open and closed to see if that solves the problem.

- 9:44 am EST: Launch of the Orion mission scrubbed for today,if the valve issue can be fixed today, NASA will try again tomorrow.


Live launch coverage of Orion begins on NASA TV at 4:30 a.m. EST with the link below:

[Update] Successful space launch of GPS Satellite with Delta 4 rocket from Cape Canaveral

Dear readers,


yesterday night, the United launch Alliance performed with success its space launch of GPS satellite (GPS IIF-5) for the US AirForce. The payload has been orbited by the Delta 4 rocket developed by the private company. The launch took place from the Space Launch Complex-37 in Cape Canaveral, Florida at 8:59 pm EST on Thursday February 20th.

GPS IIF-5 is the fifth in a series of the next-generation of GPS satellites and will join the navigation system utilizing 24 spacecrafts in 6 different planes in orbit around 17700 km of altitude. This ultimate generation of satellite provides an improved accuracy and enhanced performed for GPS users, for civil and military applications.

ISS switches from Windows to Linux to improve reliability

Dear follower,


the United Space Alliance, which handles the computers boarded on the International Space Station in association with +NASA , has announced that the Windows XP computers aboard the ISS have been switched to +Linux . “We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable.”
Credit: 
This changing, it's not a surprise. +Linux  is the scientific community’s operating system of choice. The +CERN Large Hadron Collider is controlled by Linux. +NASA and +SpaceX ground stations use Linux. Actually, for critical applications that require absolute stability, which most scientific experiments are, Linux is the obvious choice. The fact that the entire OS is open source and can be easily customized for each experiment is obviously a very big draw, too.
