Brooklyn Father And Son Launch Homemade Spacecraft 243

Adair writes "A father and son team from Brooklyn successfully launched a homemade spacecraft nearly 19 miles (around 100,000 feet) above the Earth's surface. The craft was a 19-inch helium-filled weather balloon attached to a Styrofoam capsule that housed an HD video camera and an iPhone. The camera recorded video of its ascent into the stratosphere, its apogee where the balloon reached its breaking point, and its descent back to earth. They rigged a parachute to the capsule to aid in its return to Earth, and the iPhone broadcast its GPS coordinates so they could track it down. The craft landed a mere 30 miles from its launch point in Newburgh, NY, due to a quick ascent and two differing wind patterns. The pair spent eight months researching and test-flying the craft before launching it in August. Columbia University Professor of Astronomy Marcel Aguera said, 'They were very good but also very lucky.'"

    19 miles is still in the stratosphere.

    • When the atmosphere gets thin enough it's "space"; 19 miles is stretching the definition a bit, but people of good faith can disagree on where that is. The WPIX article saying they sent into "into orbit" is of course dead wrong. It wasn't even a suborbital ballistic flight (like Alan Shepard's first).

        It's entirely possible to go to space without reaching escape velocity. You will get there as long as you're moving up and your thrust is greater or equal to the force of gravity. Escape velocity only concerns something moving up without any thrust at all. Of course, we can't build anything that will maintain thrust equal to the force of gravity for long enough, but if we could, we could go to space... at a snail's pace!

      To be fair, atmospheric pressure at 19 miles is just a little under 1% of what is at sea level and about equivalent to the atmosphere of Mars.

        What is so sad is that joke of a "spacecraft" this gets a strong mention in the press (and on Slashdot) while a real spacecraft... using a helium balloons as a 1st stage to get altitude is being used in a genuinely innovative fashion for something new with rocketry. See:

        http://www.arcaspace.com/en/home.htm [arcaspace.com]

        ARCA was successful with their last launch attempt.... which was launched yesterday. No video links yet, but the official page says that the launch attempt was successful. Yeah, attaching rockets to a balloon is something being considered.

        FYI, ARCA (Aeronautics and Cosmonautics Romanian Association) is using this flight as a part of the testing regime in order to get TO THE MOON! They are a Google Lunar X-Prize team who is making some real progress and sending stuff up. They are also doing it on a budget of a mostly volunteer team in Eastern Europe. The main reason for using the balloons is not really the altitude issue, but that does simplify the rocket nozzle designs as it can be tuned to a near vacuum rather than having to deal with atmospheric flight (it makes a difference). Also, if something goes "boom", that explosion happens high up in the sky and over the Black Sea instead of over a populated area, making the issues of a launch pad much less of a problem.

          These guys are doing some thing almost as cool though sticking to purely amateur ideals. Luckily for science loving people they've gotten a lot of press coverage. Unfortunately their latest launch failed on the pad, due to an issue with power, and they wont be able to attempt another test for six months odd. Still it is great to see people attempting to move past the generic rocket club stuff people have been doing pre-fab for 40 years.

          They definitely, along with some other examples, inspired me to push my friends to start doing serious engineering projects for fun. So far our list of things to attempt comes from any thing cool on TV that come with the stupid warning 'don't try this at home!'.
        • I have to disagree with your statement that ARCA is doing something 'genuinely innovative' by using a balloon for the first stage. The concept is called a 'Rockoon' and was pioneered in the US in 1949 and has been used extensivly by JP Areospace, (among others), a small US company that has been working with balloons and rockets for over 30 years.

      that 19 inch helium ballon doesn't have much of a payload, so you can't stick a big model rocket in there.

      You *could* possibly stick a small model rocket, and have the iPhone fire it when they reach high enough an altitude. A small rocket with 5 seconds of thrust maybe.

      You could even modify the shape of the exhaust nozzle for optimum vacuum performance since there's almost air there .

      while that would be cool, it's still nowhere near enough to actually get it in space....

    1. It is a balloon. Not even the people who fly these for a living call them spacecraft. Says WikiP: "A spacecraft is a craft or machine designed for spaceflight." This thing popped when it rose above too much atmosphere. It was not designed for space. It was still in the stratosphere when it failed according to design.

    2. The Karman line is the generally accepted edge of space at 100 km (62.5 mi). This is where an aircraft would have to fly so fast to get lift from the thin air that it would achieve orbital velocity in the attempt and so wings would be superfluous. The US has awarded astronaut wings to pilots flying above 50 miles. This doesn't change the objective criteria of the Karman line.

    3. The CSXT GoFast achieved space altitude (72 miles) on May 17 2004 and is the only unmanned civilian craft to do so to date. It was designed for a flight profile carrying it into space and so was a spacecraft. As was SpaceShip One, the only civilian manned spacecraft to date.

    4. Reaction Research Society hit 50 miles in 1996. Hunstville L5 passed this 19 mile mark, but was ballooned launched and so not entirely spacecraft.

    5. No amateur spacecraft made from off the shelf or home made components has achieved even a 50K ft altitude according to Tripoli records. With Tripoli and the National Association of Rocketry's recent facing down ATFE over the definition of 'explosives', the FAA et al. is redefining amateur rocketry to include power up to 200,000 lb-ft sec and a concominant (and easily achieved with this power) 93 mile altitude. Most motors in this range are "experimental" ie. home made, but there are a few commercially available motors that can be staged and/or clustered for this power, the 152mm dia + 96" Loki Research P motor at 80kN-sec each being the largest you can currently put on your credit card. 11 of these will put you just under the FAA's proposed limit. 12, and you have to apply to NASA's office of space transportation for a permit. Expect an amateur spacecraft to make the flight, because now it's a matter of qualifying for the license and buying the parts.

        Wrong Wikipedia on the Karman Line [wikipedia.org] Theodore von Kármán, (1881–1963) a Hungarian-American engineer and physicist, calculated what approx altitude would force you to achieve Orbital Velocity (27,000 kph) to stay there, and came up with about 100km. It's not exactly 100km, and it varies slightly, but it is indeed a nice round number, so they decided to keep it.

    When its tumbling around up high and the camera goes upside down you can see the curvature of the earth inverted. Pretty weird looking.
    In fact, on its way down where you can still make out trees and stuff, there seems to be a curvature.
