"Understanding that our understanding might be wrong is essential, and trying to figure out the ways we may be mistaken is the only way that science can help us find our way to the truth."

"One bit of advice: it is important to view knowledge as sort of a semantic tree -- make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to."

ESA’s Rosetta mission has soft-landed its Philae probe on a comet, the first time in history that such an extraordinary feat has been achieved.

Update: One Survivor, One Fatality in Virgin Galactic’s SpaceShipTwo Flight Accident

Officials from Virgin Galactic and Scaled Composites have confirmed one of the pilots was killed and another was injured in a major anomaly during a test flight of SpaceShipTwo today (Friday, October 31). The names of the pilots have not yet been released. During a hastily-called press conference, officials said launch of the WhiteKnightTwo plane carrying SpaceShipTwo occurred at 9:20 am PDT this morning and at 10:10 am, SpaceShipTwo was released for its test flight to the edge of the atmosphere and space. Two minutes into its flight, SpaceShipTwo encountered an anomaly. Officials had no immediate cause but the rocket engine is the first point of concern.

Yes, the jet engine has definitely shrunk the physical distance between people in different geographical locations. However, the internet can bring people and their ideas together almost instantly. Both of these capabilities have greatly changed the way we interact with the world we live in.

As annoying as the noise coming from the pending internet connection of a dialup modern might be to some, it is something I don't mind listening to once in a while. It's number 38 on the list.

Does the science community usually open up their data to the public? If not, I think this is a step in the right direction.

Via reddit
Anyone can access collision data from the Large Hadron Collider through the new CERN Open Data Portal.

Update from +Virgin Galactic
 
Thank you for your messages of support; they are much appreciated at this difficult time. There is much speculation about what exactly caused today’s accident, but we will not have all the facts for some time yet. In the meantime, we wanted to confirm a few key details.
 
First, the Virgin Galactic team is cooperating with our partners at Scaled Composites and with the US National Transportation Safety Board (NTSB), Federal Aviation Administration, and local authorities on the investigation.  The NTSB is scheduled to arrive in Mojave tomorrow morning to commence their investigation. 
 
Second, local authorities have confirmed that one of the two Scaled Composites pilots onboard SpaceShipTwo died during the accident. The other pilot parachuted to the ground, and is now being treated at a local hospital.  All of us are deeply saddened by today’s events, and our thoughts and prayers are with the families of all those affected by this tragic accident.
 
At a press conference earlier today, our CEO, George  said: “Our primary thoughts at this moment are with the crew and family, and we’re doing everything we can for them now.  I’d like to recognize the work of the first responders who we work with in the Antelope Valley for their efforts on behalf of the team.  We’re also thinking of the team members that we have at the companies that have been working on this program. Space is hard and today was a tough day.  We are going to be supporting the investigation as we figure out what happened today.  We’re going to get through it.  The future rests in many ways on hard days like this, but we believe we owe it to the team, that has been working so hard on this endeavor, to understand this and to move forward.  And that is what we’ll do.”
 
Lastly, Richard Branson is on his way to Mojave as we speak to visit with our team.

We’ll post more information when we are able.

"Our first concern is the status of the pilots, which is unknown at this time."

Sad news. From what I can gather so far, there might be fatalities in this accident.

#SpaceShipII
 
Virgin Galactic's partner Scaled Composites conducted a powered test flight of SpaceShipTwo earlier today.  During the test, the vehicle suffered a serious anomaly resulting in the loss of the vehicle.  The WhiteKnightTwo carrier aircraft landed safely. Our first concern is the status of the pilots, which is unknown at this time.  We will work closely with relevant authorities to determine the cause of this accident  and provide updates as soon as we are able to do so.
