SkyCube Camera Demonstration

SkyCube Camera

A successful demonstration of SkyCube’s 4D Systems JPEG UART camera talking to its computer processor board.

The processor controls the camera and converts its raw image data to ASCII (text). It then sends the ASCII out one of its serial ports. The ASCII image is captured with a logic analyzer and displayed on a PC laptop screen.

The camera is operating at its lowest possible resolution (80×60) for the purpose of the test. This is obviously not how it’ll be used it in space, but it does show that all the pieces are working, and that they can talk to each other. For more details on the project, go to http://www.skycube.org/

Live TV broadcast for launch of HTV-3 CubeSats

FSpace, the team of young engineers and students at the FPT University who developed the amateur radio F-1 CubeSat, report on the final launch preparations for the HTV-3 cargo vessel that will carry five CubeSats to the International Space Station (ISS).

FSpace say final inspection was performed on July 9, and from July 13-15, a rehearsal was conducted simulating the launch operation. Late access cargo loading will continue until July 19 then the hatch will be closed and the H-IIB launch vehicle with the HTV-3 will be moved to the launch pad. The launch is planned for July 21 at 02:18 UT.

PongSats – 1000 Student Projects to the Edge of Space

A PongSat

On September 22 it’s planned to send 1000 student projects built into PongSats (ping pong balls) to the edge of space.

These experiments and projects are made by those in kindergarten, university professors, high school science classes and home schools kids.

Projects range from plant seeds to filling a PongSat with a marshmallow. At 100,000 feet (30 km) the marshmallow puffs up completely filling the ball. Then it freeze dries. The student gets to hold in her hand the direct results of traveling the top of the atmosphere.

The launch of the PongSats will take place from the Black Rock desert in Nevada. The vehicles that carry them are called High Rack. They are made of foam and carbon fiber. There are four separate telemetry links to the High Rack tracking it during the flight. At the end of the flight the balloon is released and the High Rack descends by parachute.

It will take four High Racks, each with its own balloon to carry the thousand ping pong balls.

SkyCube: a social space mission

skycube.

Southern Stars Group LLC, the company responsible for the popular SkySafari apps for iOS, Android and Mac OS X, is thinking a little bigger with its next project. The publicly funded SkyCube is a miniature CubeSat satellite that will orbit the planet, transmitting low-resolution images of the Earth while broadcasting short messages from sponsors in the form of data pings. In short, it’s the world’s first social space mission.

The hardware involved in the project isn’t anything we haven’t seen before. The satellite itself is a 10x10x10 cm (3.9 cubic-inch) “1U” CubeSat, which is the current leading picosatellite standard with nearly 100 of the devices built and launched to date. The SkyCube will be the second payload on a SpaceX Falcon 9 rocket, set to launch sometime in 2013.

Once deployed, it will orbit more than 300 miles (483 km) up, taking low-resolution pictures and broadcasting short, simple messages from the project’s sponsors as it crosses over most of the world’s inhabited regions. At the end of the mission, the SkyCube will deploy its 10 ft (3 m) diameter balloon, making it visible from the Earth, with a brightness akin to that of the Hubble Space Telescope. If everything goes to plan, the miniature satellite will eventually return to Earth, brought down by atmospheric drag.

So if you want to broadcast your own short message from space, the Southern Stars Group has got your back, with pledges starting at just US$1. This base option gives you a ten-second time slot on the mission, in which you can broadcast a single 120-character message. The sponsorship options go all the way up to $10k, for which the company will fly two people out to Cape Canaveral from anywhere in the continental US. From there, sponsors can watch the satellite lift off and once it’s successfully in orbit, they can control the SkyCube for an entire day to take pictures, send messages, or just sit back and contemplate the balance of their bank accounts.

The company is also making use of its app-making skills, creating applications for both iOS and Android. These will allow users to track the satellite, send messages and request images.

The SkyCube marks the next step in a series of initiatives and projects that are making space programs far more accessible to the general public. Rocket and spacecraft construction company Interorbital Systems recently announced its project to make space available to all. For $8,000, customers receive both a TubeSat Personal Satellite Kit and launch to low Earth orbit. That’s significantly cheaper than the SkyCube’s CubeSat miniature satellite, which costs around $100k to put in orbit.

So, have something important to say? Well, in 2013 you’ll be able to say it from space. The SkyCube has 57 days to go on Kickstarter, meaning that you’ve got until Wednesday September 12 to secure your chance to “tweet from space.”

PIE1 – Raspberry Pi Sends Live Images from Near Space

A Raspberry Pi

Dave Akerman M6RPI has used a Raspberry Pi computer board as the flight computer on a High Altitude Balloon (HAB) and sent back live images from near space at an altitude of almost 40 km.

The balloon, appropriately called PIE1, was launched from Brightwalton, in Berkshire on July 14, 2012. The images were transmitted on 434.650 MHz (300 bps, 600 Hz shift) in the amateur radio 70cm band using the Slow Scan Digital Video (SSDV) standard.

PIE1 reached an altitude of 39,994 metres and images were received as far away as Northern Ireland (that’s over 500 km, not bad for just 10 mW on 434.650 MHz!).

See the images sent by PIE1 http://sanslogic.co.uk/ssdv/live

SkyCube uses Kickstarter for Funding

PC World magazine reports that a fundraising campaign for the satellite, SkyCube, launched on Kickstarter last weekend (July 14) with the goal of raising US$82,500. Kickstarter is an online service popular with entrepreneurs and startups for raising money.

SkyCube-SatelliteThe article says the SkyCube team is led by Tim DeBenedictis, a self-described “space nut” and the man behind the popular Sky Safari smartphone app that provides a guide to the stars.

It will take pictures of Earth with three VGA cameras and deliver 120-character messages to smartphones running a SkyCube app. The messages will be collected on Earth and transmitted to the satellite about once a day, where they will be stored in memory and broadcast every 10 seconds. In addition to the app, anyone with a fairly modest amateur radio-type receiver might also be able to pick up the broadcasts directly.

The PC World article incorrectly says that Chris Phoenix is the projects radio expert, he isn’t, Chris is doing the firmware not RF.

SkyCube will be the first 1U CubeSat to carry an inflatable balloon. When the 3-meter reflective balloon is deployed 90 days after launch it should be visible to observers on the ground. A few weeks after deploying the balloon SkyCube will burn up in the Earth’s atmosphere.

It is understood they are planning to use 915 MHz and hope to launch on a SpaceX Falcon 9 rocket in the first half of 2013. http://www.southernstars.com/skycube/
