Announcing Our Crowdfunding Campaign

Next month, we will launch a crowdfunding campaign for NOVA, our crowd-flyable CubeSat.

The primary goal of this campaign will be to fund the supporting infrastructure for the mission. This will include a satellite assembly lab and ground station, plus the remaining assets typically required for any mission of this kind.

We also have something to offer for backers that are interested in developing their own missions.

The highest-tier reward of the crowdfunding campaign will be microNOVA, a CubeSat development kit packed into a 3D printed 1U (10 x 10 x 10 cm) frame. This hardware product can be utilised for fast prototyping of CubeSat-specific applications, algorithms, or mission scenarios. Plus, software created through this development kit will be compatible with our future orbital mission, NOVA, that we aim to launch in Q4 2021!

History of Cubesats: The Next Ten Years (2003-2012)

For the next ten years, cubesats missions continued to be launched at a rate of few per year. Many of the cubesats were continuing to be built by university teams, but some came from government space agencies and emerging New Space industry players. There were no special purpose launch vehicles for this type of satellites, so users had to rely on rideshare opportunities and use low-cost providers that relied on refurbished ICBMs as launch vehicles. 

But this kind of rockets don’t have the best reliability record. Sometimes it caused substantial setbacks, such as one that happened in July 2006 when Dnepr space rocket crashed soon after launch, bringing down 22 cubesats with it. While it was obviously disappointing for mission designers, many of those cubesats had flight spares available and were relaunched in the later years. Typically, a small budget cubesat of this period had an imaging camera and one other additional science experiment, such as radio communications device or particle detector but sometimes more unusual mission. In this chapter we’ll try to describe a few of more interesting examples. 

The first the mission on our list was called CUTE 1.7+APD.  It was a 2U cubesat built by a Japanese team from Tokyo Institute of Technology. It had an interesting distinction of using a Windows CE PDA from Hitachi as a primary onboard computer. An was launched in February 2006 and operated successfully for about a month. However, the consumer PDA is clearly not the best possible option for a space mission on-board computer. The satellite stopped responding in March of the same year, most likely due to radiation-triggered hardware fault.

Other interesting missions during these years were various tests of tethers – wires used to connect structures in space. One such research program was MEPSI, and it included a number of nanosatellites designed by DARPA. While not implemented in any standard form-factor, they were pretty close in dimensions and mass to regular cubesats. There were deployed in pairs from Space Shuttle Endeavour in November 2002 and again from Space Shuttle Discovery in December 2006. The purpose of these missions was to test radar detection of two satellites connected by tether. This program was terminated before the conclusive results were obtained but the second pair operated in space for a few days at least.

MAST was another experiment with tethers, this time built by Tethers Unlimited and launched in 2007. It was composed of a mother and daughter satellites connected by 1 km long tether that was supposed to deploy after launch. The daughter satellite would climb along this tether back and forth to prove feasibility of this architecture. But unfortunately, this mission ended in failure as well. The satellites were operational, but the tether didn’t deploy. Here is the illustration of how it would look in deployed state:

As a rule, mechanical failures are quite common in space environment. Cold welding or outgassing can interfere with moving parts and connections or stick them together. Dynamics of mechanical structures in microgravity and vacuum conditions are very different from the ones on the ground. Testing these aspects requires specialized facilities. There is a tower in Bremen, Germany that allows to drop various experiments for a few seconds of microgravity. And one of  our teammates has actually used this facility for his own research project, namely Drop Your Thesis. But this will be a story for another time.

Astrobiology (biological experiments in space) was another emerging research area that cubesats were used for.. The first mission of this kind was GENESAT, a 3U cubesat launched in December 2006, that was also the first cubesat from NASA. Its mission was to measure levels of protein activity in cultured bacteria. It was using a number of small cells filled with bacterial cultures that were brought to life in space using the sugar solution. Then special LED triggered the protein to emit some level of light and that was the essence of this biological experiment.

The next important area tried via cubesat technology was solar sail technology. This type of propulsion holds a lot of promise for space exploration, both now near and in the future. It also helps that this tech can be tested on a smaller scale before building full-scale solutions. The first solar sail mission was NanoSail-D. It gained a bit of infamy as it was attempted to be launched on SpaceX Falcon 1 in 2008. But unfortunately, it was launched on the 3rd flight of Falcon 1 which wasn’t a successful one. This also highlights the importance of having a flight spare – because it was launched as NanoSail-D2 in 2010, and this time it was a successful mission. Notably, the launcher used (Minotaur IV) was a converted ICBM, but an American one. That cubesat was deployed in a slightly unusual manner, from inside another satellite called FASTSAT. There was a bit of drama in this story! The satellite didn’t deploy immediately and was stuck to a mother satellite for a while. But somehow is able to detach itself a few weeks later and it became operational. It had no solar panels, so it was operating on batteries only and didn’t live for long. But nevertheless, it was a successful mission and had the honour of the first successful cubesat mission, equipped with solar sail.

To conclude the story, it should be mentioned that between in years 2003 to 2012 the rate of cubesats launches was relatively low. A few per year usually, with up to 25 in year 2012, excluding the unsuccessful launches. The big breakthrough in launch numbers came next year. But this will be the topic for the next part of our cubesat history series.

Nurturing The Minds of Tomorrow – A Perspective From Space

A guest post from one of our team mates

Children are both the makers and the markers of healthy, sustainable societies. According to UNICEF, children represent one third of the world’s population, in today’s numbers, that would be approximately, 2.2 billion children and they represent a significant factor for the future development of the society on a planetary scale.

Sustainability is the ability to exist constantly. Sustainability has a lot of definitions, but, regarding humanity, it all comes to one thing, the ability to thrive and advance as a race, species. We as humans are a race that leans towards technology. We see the technology as an answer and a solution to sustainability. Therefore, we should motivate and educate our legacy to follow that path. There are many possibilities and ways to use technology to achieve and maintain a sustainable society, but we will consider only one of them.

Space exploration is one possible tool that might allow humanity to achieve and maintain a sustainable society. We are very much dependent on resources that might and eventually will be drained, exhausted on our beloved planet. The only other place to find resources is the vast space. We need engineers in order to explore and promote space exploration, we should encourage our legacy to follow that path. Motivation and encouragement is not always easy when it comes to young minds. Children learn and explore through play. Their curiosity is limitless, pure and naïve.

There are many tools that will help us, adults, to guide the young engineers, explorers and innovators. Most of them are simple, free and at hand. Read to them, talk to them and tell them about the planets, moons, stars. Make paper rockets, tell them a story about Titan, Saturn’s moon, guide them on a journey that will feed their imagination.

Hands-on learning is another way. Children love to create and use their hands. Young and gifted makers and engineers could play with different building block and create spaceships and orbital stations. 

Only by building they can build the confidence to continue exploring. As adults, we need to give an example, we need to teach them to never give up, learn every day and keep looking into the future. So, to summarize, how do we get more young space explorers? By letting them explore the universe using their imagination.
