My Sun Chaser Blog – Team Meeting 20

The Education Team had a few resources to finish for the outreach lesson and some new equipment to test. They quickly organised the rest of the group to help prepare flash cards and test the refraction glasses (rainbow light from every light source!). The solar powered toys are great fun and were easy to put together (The little solar-powered fan can turn at a surprising rate!).

One of the team’s engineers soldered the replacement GPS module to the flight computer and took it out for a test. We all waited in anticipation and after a few tense minutes he returned triumphant with a steady stream of telemetry being collected by the mobile ground station. I love the effect these triumphs have on the team and it’s a great feeling to be a part of it.

I got quite an education as two experienced members of the Flight Team spent the meeting teaching the rest of us how to use the smartphone tracking system to locate the probe when it lands. I’m really looking forward to the next stage of flight training now as we’ll be learning how to attach and fill a balloon in preparation for a probe flight!

While one of the engineers tested the Flight Computer, the rest of the Engineering Team continued working on the probe I’ll be flying in. They finished a separate compartment for my friend ‘Tweedy’ (St Mary’s the Mount Primary School’s mascot) as there won’t be space for him in the main probe. They’ve also made anchor points in both Tweedy’s compartment and the top of the main probe so that the two can be attached (although they will be separated by several metres of line so we’ll have to shout to each other if we want to talk – maybe the team will fit walkie talkies if I ask them). Next week they’re going to start cutting out the antenna and camera ports.

My Sun Chaser Blog – Horizon’s First Outreach Lesson

In previous years the Horizon team have shared advice, code, designs, research and suppliers’ details with many other schools and pupils. They’ve even travelled to Cambridge (and on to Essex) to help the Science Department at Attleborough Academy Norfolk track their first probe, ‘Monarch 1’.

I was really excited to find out that this year they’re taking this support a step further and running their first outreach programme. The team are working with the fabulous Year 6 pupils at St Mary’s the Mount Primary School and are very grateful to the school for volunteering to work with them in developing their programme.

Their Education Team (Two of Horizon’s Physicists) have planned a programme of three lessons: ‘The Solar System’, ‘The Sun’ and ‘Our Atmosphere’. On Wednesday they ran the first ever Horizon outreach lesson. The lesson explored our Solar System, looking at the true distances between the planets, the position of the Asteroid Belt, the Oort Cloud (named after the Astronomer, Jan Oort) and Comets.

Before we arrived the class had held a vote and decided to name their mascot (who will be flying aboard the first Sun Chaser probe with me!). Let me be the first to introduce you all to my new friend ‘Tweedy’:

The team led the pupils in making posters about each of the planets, the asteroid belt and comets (using a class set of ipads and several good books). There were some fantastic posters, some great colour drawings of planets and plenty of interesting discussions and questions about Space.

Outreach 1 - Making postersOutreach 1 - Research

With posters ready, the pupils headed out onto the playground in teams to make a scale model of the Solar System with inflatable planets (toilet roll helped to measure the distances). Once the solar system was made, the long and short period ‘comets’ began to orbit the sun.

There was a lot of excitement and we had a great time discussing the Solar System, advances being made by ‘New Space’ companies and developments that the pupils might see in their lifetimes. The Education Team did a fantastic job and their passion for Physics really shone through. I’m very excited about next week’s lesson about ‘the Sun’.

My Sun Chaser Blog – Launch postponed…

The team were preparing to launch the first probe (and me!!!) on Saturday 18th April but the weather turned on us and with the wind blowing across the UK from North East to South West the probe was headed for a watery landing in the Irish Sea on any of the planned launch days. April is always a challenging month for a launch and the team seem pretty resilient about scrubbing the launch and searching for another date.

Launch cancelled - Out to sea Sat 18th AprLaunch cancelled - Out to sea Sun 19th Apr

My Sun Chaser Blog – March

March started with great excitement as I joined the Education Team on a visit to St Mary’s on the Mount Catholic Primary School. We got to meet the teacher of the class that the team will be working with and the team got a tour of the school as well as a chance to sit down and ask all of the questions they’ve been saving up. It was a great visit and St Mary’s is a beautiful school.

St Mary's Classroom

Following their meeting at St Mary’s on the Mount, the Education Team set about splitting the class list up into groups, writing instructions for each activity and filling our the final details for each of the lessons.

The last lesson will be about the Earth’s Atmosphere and will feature Horizon and some of it technology (hopefully including a little helium filled weather balloon so that pupils can float things around the classroom).

tm15mattcwk

Though the formulae are finished they still had to be incorporated into the Sunrise Calculator. With so many changes needed and a few bugs already present, the Modelling Team decided to completely rewrite the code. It was very time consuming but by the end of the month they had a beta version which was stable and tested well.

The Publicity Team split their time between tracking down potential sponsors and researching possible contacts for local and county news organisations. They also prepared a press release for the first launch to go out in April. Their efforts were successful as the team was joined by two new sponsors, one of which is a local Aerospace Consultant.

With the launch approaching the Engineering Team was under a lot of pressure. They finished the build for the Flight Computer but testing revealed a problem with the GPS which they didn’t have time to resolve before the Easter Holiday.

tm16emanuelbeacon

Testing of the beacon (which will help the team locate the probe when it lands) proved it was loud and made the engineer in charge of it a little unpopular with the rest of the group. The design evolved when they noticed that the Arduino couldn’t output the power needed for the LED arrays and it was decided that they would use the Arduino to control the circuit via a transistor.

The engineers also took delivery of two 16MP cameras (a Canon A810 and a Canon IXUS 140). They were quick to customise the firmware and install intervalometer scripts which would automate the cameras. The tricky part was battery life testing. Although the GoPro Hero 2 has an extra battery giving it over 3 hrs runtime and the Canon A810 runs off Energiser Lithium Batteries, the Canon IXUS 140 only has a Lithium Ion battery which wouldn’t even come close to lasting the flight. The team had to build a custom power circuit to ensure the camera could shoot photos throughout the entire flight.

The extra work meant that the team were late to start building the probe though they did make some progress. This means that the first week back after the Easter Holidays is going to be very busy.

tm15lizteachtm17liamteaching

With the first launch coming up soon a few of the team took time out from their regular roles to train each other for the forthcoming launch. They ran lessons on Probe Flight Planning, attaching the parachute to the payload and filling the balloon. They had a lot of fun trying to master some of the knots involved. One highlight was a team member who managed to zip tie their glove to the balloon – you don’t want to launch yourself!

William with banner

The team asked a GCSE pupil who studies Art to design a pop-up banner for their stand. The banner design they came up with was really impressive and was used at both the Open Evening and the Think Tank.

My favourite part of the month was the ‘Meet the Experts’ session at the Think Tank and Planetarium in Birmingham. Volunteers from the team set up a stand in the centre of the Think Tank and talked to members of the public about their roles and the upcoming mission. They projected footage from previous missions onto a big screen which stopped many visitors in their tracks. The best part of the whole stand was a colouring area where children who visited the stand could let their imaginations run riot as they made pictures of whatever inspired them.

Everyone is excited and nervous as April is the time of the first launch and the start of the outreach programme. I’ll be flying aboard the probe and if the team gets the timing right the view will be spectacular.

My Sun Chaser Blog – February

Having been around for a few months now I’m beginning to feel like one of the team. I got some great selfies with some of the sub-teams during of the meetings this month. I’ve also got lots to report on.

The Publicity Team split their time this month between continuing their work on the promotional posters for a display at the Chasewater Innovation Centre and identifying new potential sponsors for the Sun Chaser mission. They also put the finishing touches to an infographic detailing some of Project Horizon’s achievements since it began – it’s impressive work!

Horizon Achievements

The Modelling Team have done some amazing work and have added a number of new features and refinements to the Sunrise Calculator. One of the key questions was how to deal with refraction of sunlight in the Earth’s atmosphere. When their research reached a dead end they reached out to Dr Helen Mason of the Department for Applied Mathematics and Theoretical Physics at Cambridge University. Dr Mason was heading out on an expedition but passed their enquiry to Dr David Pike (of Cambridge University’s SunTrek Team). Dr Pike was able to put the team in touch with Dr Andrew T. Young at San Diego University who was able to recommend a really helpful journal article on the subject. After a lot of reading the team adjusted their model using the calculations in the article.

tm13model3

Never content with just achieving the basic goals the team also added the ability to predict the times of Civil Dawn (when the Sun is 6 degrees below the horizon) and Nautical Dawn (when the Sun is 12 degrees below the horizon) to the model.

All of these new features mean that the code will need to be mostly rewritten which will be quite a challenge.

The Education Team drafted and re-drafted their first two lesson plans.

tm13edu and pubHaving added a little detail both plans were sent to their partner school, St Mary’s on the Mount Catholic School. They also put together a shopping list of resources to support their lessons.

Next month they’ll be heading over to St Mary’s School to discuss the lessons, resources and indoor/outdoor spaces.

The month did not start well for the Engineering Team as a small misreading of a circuit diagram led to the sudden and explosive death of the Arduino Pro Mini in their test kit (a replacement was promptly put on order). Despite this early setback the team quickly recovered and got started on the task of building the probe’s systems. This began with the more experienced members from last year’s mission teaching the others how to solder.

Unboxing rapid 2

The highlight of the month was the arrival of two large boxes of equipment from the team’s Sponsors; Rapid Electronics and Proto-pic.co.uk. The engineers wasted no time cutting into the boxes and unpacking all of the new equipment. The boxes contained all of the electronics the team needs (except for a few antenna connectors which are out of stock, but should arrive soon). They also contained some torches as the team will be preparing for launch between 2 and 4am in pitch black so good lighting will be essential.

Following the arrival of the new equipment the Engineering Team went back over the flight computer circuit, adding in the last few connections and taking turns to check it against the original design. The new tracking firmware was quickly uploaded and was ready for testing by the end of the month.

tm13engineers1

The other half of the team worked on two projects; camera modifications and the design for a beacon to make the probe (and me) easier to find when it lands. They quickly figured out how to customise the camera firmware of last year’s camera. The beacon is taking a little more work. They have set up an Arduino to control eight LEDs and a pair of speakers on the outside of the probe. The lights and sound will pulse to make it easy to find the probe (and me) when it lands.

The team were humbled to receive the support of four new sponsors for their Sun Chaser mission. It was heartening to see that many of the sponsors had supported the Beat Felix mission last year.

The second highlight of the month was a plug for the Sun Chaser Mission on Twitter by BBC Click’s Kate Russell (I wish she could have seen the excitement that flashed around the room when the team found out!).

My Sun Chaser Blog – January

The team came back well rested and fizzing with excitement. December has quickly faded into the past as I found myself swept up by the busy new atmosphere.

This was the month for videos as the team put the finishing touches to the Beat Felix Movie and released it. This was quickly followed by a brand new trailer for the project:

Once the team had a few videos online they set up a YouTube Channel to host them all.

They’ve even started to collect together videos from around the web on their channel to highlight the big developments taking place in the Space Industry as humanity enters a new Space Race.

tm10edu2 tm9edu1

The Education Team started working on three lessons (one for each of the themes). They also brought in some ‘lesson resources’ which they tested extensively. During the lessons they’re planning to screen some footage from one of Horizon’s launches, experiment with Solar Cells, build a model Solar System to scale in the playground and possibly inflate a weather balloon with helium, amongst other things.

Equipment lay everywhere as the Engineering Team looked over the old probes for inspiration. There were several discussions began about how big the probe would need to be to carry all of the mission critical equipment as well as myself and the partner primary school’s mascot. The team also received new radio modules and a new GPS board so they’re starting work on the Flight Computer. First they have to build a testing platform to check the modules all work. There was a little soldering work to do and one team member from the Beat Felix Mission took it upon themselves to teach the other engineers.

Through a division of labour the Engineers have also started learning to flash and edit firmware for the Canon camera.

The Modelling Team brought in a little outside help from another pupil in the sixth form. They needed help finishing the program for the Sunrise Calculator as the learning curve for the language has been steep. The calculator was quickly finished but testing revealed a couple of inaccuracies and it was back to the drawing board. Fortunately the problems were easy to fix but it meant that the Sunrise Calculator Code will need to be rewritten. The team are not happy with the accuracy yet and they plan to contact Dr Helen Mason at Cambridge University for some help accounting for the refraction of light in the atmosphere.

Samosa Sale 2015 (1)

The Publicity Team have been tremendously busy and have split their time between working on new posters about previous Horizon missions and planning the Samosa Sale. The sale was a tremendous success and an incredible 550 samosas were sold in under fifteen minutes. I was impressed at how quickly they got set up, sold out and cleaned up after themselves. It was like a military operation!

The best news of the month was that two new companies would be joining the project as sponsors for the Sun Chaser Mission.

My Sun Chaser Blog – December

It was a quiet month with only two meetings and a lot of the team tied up with the Panto, Concerts, etc. Progress slowed and everyone shifted into a ‘Holiday Gear’. One piece of fantastic news is that the team has been invited to the Think Tank Planetarium in Birmigham.

They will be the experts at a ‘Meet the Experts’ day and will be chatting to the general public, talking about their roles, showing off some of the technology and screening past launches along with footage from the Stratosphere.

Everyone was very proud and they’re looking forward to having a good look around while they are there.
