Dragon and Liberty

This morning, after many delays, SpaceX's Falcon 9 lifted off for a rendezvous with the International Space Station. As this blog reported back in February '009, SpaceX Aims High, this docking was originally planned for May-November 2010. The 18-24 month delay is partially due to NASA and Russia's stringent requirements for docking with ISS. SpaceX claims that they can turn Falcon 9/Dragon into a human-rated system in 3 years. We wish them Godspeed and a successful flight, but rocket science is full of delays. Meanwhile, with less of a media spotlight, ATK is forging ahead with their Liberty booster. Outwardly similar to the cancelled Ares I, Liberty has for a first stage the 5-segment solid rocket booster developed for Ares I and the more recent Space Launch System. The crew capsule will be built from modern composite materials, based on an all-composite design built and rejected for Orion. Unlike SpaceX, ATK is building a complete system without any more government funding. They are using an unfunded Space Act agreement, and funds already spent by NASA for Ares I. ATK claims that this system could be flying crew into orbit by 2015, potentially beating SpaceX. We also wish them and the other competitors every success.

The only reason ATK is doing this is that they have big influence in congress. They failed to build Ares 1, and if they want to spend their own money doing something more power to them, but obviously that's not the case as congress is subsidizing them with the SLS boondoggle.

I am still a student so i live a very stressful life. I am often busy doing homework or working on some school stuff. I often ask for help though. For example, the pile of write-ups and reports that I needed to accomplish was like impossible to finish on my own so I delegated some of the tasks to my two big sisters, my friends and some, to paid professionals. Most of the writing assignments I had was done by the www.proessaywriting.com the internet has to offer. Of course, amidst all the help that I got, I was still able to work on things on my own for the most part. And with that, a road trip with friends plus some exciting activities, like trail riding, is like the total stress reliever, making me and of course my friends, free from the worries and stresses of school life.
