SpaceX Plans 100% Reusable Spacecraft With Retrorocket Re-entry [VIDEO]

Private aerospace company SpaceX plans to develop reusable spacecraft that gently land on Earth or other planets using retrorockets, according to SpaceX CEO Elon Musk.

The idea is for both the space capsule and its rocket booster to be capable of propulsive landing, where after their reentry into the atmosphere using heat shields, the spacecraft would be lowered gently to a planets surface using rocket thrusters.

For Musks 100% reusable spacecraft idea to become reality, theres much rigorous testing to be done. So far, SpaceX has done design work to figure out if its possible.

According to Discovery, Musk said the following at the National Press Club in New York Thursday: Now, we could fail Im not saying we are certain of success here but we are going to try to do it. And we have a design that on paper doing the calculations, doing the simulations it does work.

Is this really practical? It seems like such propulsive landings on Earth would require inordinate amounts of fuel compared to the traditional fiery reentry with a parachute finish. But the Russians have been using a hybrid re-entry approach for years, using parachutes to slow down a spacecraft, and then a rocket burst just before landing to ensure the spacecraft is lowered gently to Earth.

A developmental advantage SpaceX might have is the fact that its already developing a launch escape system, which is already in the early stages of testing. And as Musk says, that systems escape thrusters are bolted in the side of the spacecraft, so we can also use it for propulsive landings. He adds that such a system could also come in handy for a voyage and soft landing on Mars.

The first version of that Dragon spacecraft is almost ready, and its designed to take astronauts from Earth to the space station and back, and has yet to be equipped with such retrorockets. Tell us in the comments, readers, do you think SpaceX should stick with the traditional re-entry methods to save money, or try to develop this precision-powered landing approach?

12 startup founders discuss working on Christmas Day

Image
Well, it would seem a trifle rude to not begin proceedings with a warm Merry Christmas. But I must askwhat the hell are you doing reading this when you should be playing your new Nintendo 3DS, or guzzling that tenth mince pie of the day? But then, you will probably ask what the hell am I doing here writing this piece on the holiest of holy-days. My excuse? I love what I do, so its not like Im really working per seplus, I actually prepped much of it yesterday. And your excuse is likely along the lines of I love all things tech, why would I switch off just because my calendar says December 25? Fair point. Confucius once said: Choose a job you love, and you will never have to work a day in your life. Nice sentiments for sure, but theres still the issue of a healthy work/life balance to contend with even for startup founders. So I asked a handful of founders and CEOs whether they would be working on Christmas Day this year, or whether theyd treat themselves to a day off. I mean, it is a...

Flipboard needs to branch its content out from US/UK, heres why

Image
Earlier this month, an eagerly anticipated iPhone app was finally launched as Flipboard took its highly acclaimed iPad app to the phone. The app has been out for a few weeks and, with the deafening chorus of cheers fading, Ive found myself shunning its beautiful and innovative design for the simple fact that its content isnt relevant enough for me. Compared to Zite , which may not be as aesthetically pleasing, Flipboard comes up wanting on content. Zite is, among others , an app which aggregates content from my social web Twitter, Google Reader and others giving it to me in a magazine style layout. Though it lacks the page flipping ingenuity of Flipboard, the reading is more varied, which is ultimately what Im looking for from a social magazine. There is credit to be given to Flipboard however, as it is addressing the issue by building an editorial team, as its founder told Robert Scoble recently . The company has also started curating content publicly too, with @flipboardtech cura...

Digitimes: Apples iPhone 5 to include smaller screen and metal chassis

Contray to previous reports that suggested Apples next-generation iPhone would include a 4.2-inch touch screen panel, Asian technology publication Digitimes reports that the device will feature a smaller 4-inch panel, adapting the rear of the device to ship with a metal chassis instead of reinforced glass. Digitimes points out that the many of the rumoured specifications expected to be featured in the iPhone 5 are the markets expectations, with sources indicating that the device will possibly adopt a significantly smaller screen than first imagined: The sources pointed out that the upcoming iPhone will not have many differences compared to iPhone 4 in terms of components and the panel will still be less than 4-inch. The iPhone 5 will adopt a 3.5- to 3.7-inch panel with a design to allow the bezel of the panel to become thinner and make the screen look larger. The inclusion of a metal back will divide opinion, given suggestions that Apple had intentionally utilised glass designs to boo...
