Moving House – the Essential Workshop

Building a New Workshop in Limited Space.

Warning – mess in progress!

It seems simple – move house, but setting up my home office and rebuilding my aerospace workshop has been a demanding exercise, but we are on the last legs of the work. The workshop requires a lot of connectivity and power. It is a last ditch line of defense against loss of power and connectivity. So what does it have:

  • 240 volt mains power
  • 2 banks of 48v batteries
  • 2 x 12v feeds (from the 48v batteries via 2 down inverters)
  • 240 volt AC inverter
  • Provision for solar power DC (coming)
  • A wired data link to one of our Internet Service Providers (ISPs) – we have 2 x ADSL and one via cable
  • A dedicated PC
  • Off air TV and links to my NAT and media server
  • Links to my 2 digital TV records and receivers
  • HF, VHF and UHF antennas
  • HF 100w HAM transceiver
  • APRS Kenwood D710 UHF and VHF transceiver
  • Test equipment.
  • Video surveillance (and its recording media and interface to the Internet is not necessarily in the garage).
  • Oh yes, tools of course and a small bar refrigerator for summer
  • Also soon we will have an air compressor and a power generator.

In fact we have less space than at our old house, but we will have much better facilities. This means it is currently hard to place the tools anywhere until we are finished, but you will get the idea of what it will look like. Jason and I will have opposite sides of a workbench. At the moment a smaller bench top is in place to make it easy during construction.

In the picture below you can see the smaller workbench covered with tools and construction gear. Also you can see the two racks for power and radio equipment. Beside them you can see the sets of small draws for small objects. Behind the workbench are some of the test equipment and lab power supplies, speakers and some of the outlets that will go on the strip of word below the shelf. The bench top will be twice as wide as the one shown here. Under the all in one PC in the left side of the shelving, you can see Jason’s HF radio and antenna tuner.

It takes a while to set this all up. Please excuse the mess for one more week until finished.

Workshop being built

Below you will see the wooden strip that will house a variety of inputs and outputs. I am holding one unit with 3 stereo inputs or outputs, an “N” connector and 2 earth points. As I will be drilling out the wood, I will not need the mounting blocks so the panels will be flush with the wooden surface. Other units have a variety of RF connectors, RJ45 data connectors, switched 12 v outlets, switched 50V outlets, Speaker connectors, USB connectors, mains connectors and much more. I was drilling the holes in the wood for the panels when I took this photo – you can see the sawdust below the panel on the next shelf down.

DSCF2108

Below I have secured power boards, audio amplifiers and a data switch under the shelf to save space. Below the data switch and to the right you can see one of the units to go on the wooden panel. It has the RJ45 and the switched 12 supply – these are connected via circuit breaker of course. You can see the LED to indicate that power is present.

Workshop being built

Below: Of course what every aerospace workshop needs – a good supply of helium gas.

Workshop being built helium bottles

I will revisit the workshop when finished and you will see the final outcome. This is a work in progress and although there is a lot of stuff on the workbench, this will disappear as we become more organised. Soon we will have peg board to hang the large tools and better organisation of the stuff currently stored in boxes.

Robert Brand – Speaker

Robert Brand Speaking at Spacefest VI 2014

Need a Speaker for that Special Dinner?

Want a passionate and entertaining speaker for your event? Someone that motivates, tells a story with enthusiasm and clarity, someone that has done it all!

Robert spoke at Spacefest in Pasadena, Ca in May 2014 and received comments such as “that presentation alone was worth the cost of registration”.

Twitter messages continued for weeks after the event. This one from @cybernova: Reminiscing on how incredible the 3D images of Mars and the lunar landing looked. Huge thanks to @robertbrand for putting that together! – 29 May 2014

So why the excitement? Robert is a skilled presenter who speaks about topics ranging from Space to Inspiring kids to think big.

Robert presenting in CroatiaYes Space! Robert is one of Australia’s leading space entrepreneurs and building space services and some a space craft. At the age of 17 he even worked on the Apollo 11 switching centre in Sydney that brought the world the feed of Neil Armstrong’s first steps on the moon. Since then he has worked in supported most of NASA’s Apollo missions, Skylab, Voyager and was stationed at the Parkes Telescope for ESA’s Giotto probe to Halleys Comet.

Robert worked in Communications for these space events, but at the age of 59 migrated quickly into the Space sector, making an instant hit world wide. He has appeared many times on ABC Radio on such shows as Linda Mottram’s Morning Show in Sydney (702), Richard Glover’s Drive (702) The Science Show, Radio Australia’s Breakfast Club and many stations around Australia.

ABC Radio’s Linda Mottram: Robert Brand’s expansive vision for Australia in aerospace is inspiring and exciting. He has the kind of energy and vision that could easily make Australia a leader. How starkly it contrasts with the mundane pronouncements from political leaders that leave so many of our best brains running for the door.

Internationally he has appeared on Radio in the UK, The Space Show in the US and This Week in Science (US). He has also had many TV appearances in Australia commenting on current space matters.

Robert speaks regularly at Spacefest in the US where he competes for a speaking spot with space experts from all over the world. He has spoken for the last 3 consecutive years on the same program as Apollo astronauts, mission controllers, planetary scientists and the key note speakers like Prof. Brian Cox (UK) and Dr Carolyn Porco. He has also spoken at ISDC and space conferences throughout Australia as well as Engineers Australia. The video below shows Robert and his son Jason (12) in Croatia launching balloons and being interviewed on Croatian TV. Robert is not just someone that did something great in the past, he is pushing forward into new and amazing frontiers.

Robert’s subjects although they appear mainly science and space oriented; include:

  • Motivating youth to achieve their goals
  • 3D slide presentations
  • Using Social Media to accelerate career change
  • Thinking outside of the box to stimulate new ideas and create change when budgets diminish
  • Wild Sports. Diving with sharks, cave diving, flying ultralights, gliding, climbing, abseiling, etc
  • Stratospheric balloons – 19 successful flights and recoveries – breaking records.

His presentation slides are mainly original material from many of his exploits, balloon and space work, but he does not repeat any text from the screen. His presentations are all about natural speech and because “he knows his stuff” he talks effortlessly to engage the audience.

Robert and Jason presenting in CroatiaHe sometimes speaks with his 12 year old son Jason. Jason is an accomplished speaker and demonstrates how a young mind can grow when not limited by normal constraints. Jason will be attempting to break the sound barrier with a Radio Controlled aircraft in the next 12 months. He will fly it as if he is in the cockpit using a video radio link and home built equipment all of his design.

Jason has spoken at Engineers Australia with his father and in front of 100 scientists in Croatia.

Robert Brand’s speaking fees are $3,000 for a dinner, lunch or breakfast engagement in Sydney. Other cities or engagements will need to be subject to a quotation.

As an introductory offer, for 2014, his standard fee, if booked direct, will be 50% off.

$1,500

Robert’s style is passionate and energetic and he moves and gesture a lot. Boring is not in his vocabulary. He sometimes challenges the audience so there is usually a bit of interaction. He also uses the occasional prop. A cordless microphone is preferred. A projector and laser pointer are essential and he must use my own PC if doing a 3D presentation.

Balon Stellar - Stratosfera 30km and RoverRobert is also the head of the Communications, Tracking and Data for Stellar – a space company sending a rover to the moon in the next three years. Jason is the Australian Student Representative. Together they travel internationally to talk about Space and to launch Stratospheric Balloons with student payloads to help stimulate space science in those countries. They have just returned from Croatia.

Robert will speak at “no cost” or a cost recovery basis on occasional Radio and TV interviews as well as presentations for small associations, not for profit groups and student focused groups. Simply ask.

13th Australian Space Science Conference Pt1

13th ASSC Uni NSWSpace Education

by Robert Brand

I was fortunate to present at the 13th Australian Space Science Conference at Sydney University a little over a week ago. The only unfortunate thing was a mix-up by yours truly and I ended up there on the wrong day. I was meant to be delivering a talk on “Triple Play in the Space Sector” and poor Alice Gorman, who was hosting the panel, was asking if I had turned up. My biggest apologies ever Alice!

I did however get a chance to present in the education stream and I am including this presentation here. My son Jason came along to help me as it was school holidays. Luckily every talk was about some of the work that he does with me, so it was pretty interesting most of the time.

Below is the PDF version of my PowerPoint presentation. It is interesting to note that we are doing so much that I can easily put together a complete presentation during a few other people’s talks. As you can see I gave my WotzUp website a plug!

NASA Canberra has a great celebration last April 13th 2013. Jason and I went down to help in the celebrations and it was a great opportunity to get up close and personal with some of the big dishes. We also got to meet a lot of great people and some of the NASA DSN’s top managers from the US.

We also meet with long time Facebook friend and now a full space friend Peter Aylward seen in the picture above right. It was a great weekend full of space fun and a special visit to the site that brought us Armstrong’s first steps on the moon – Honeysuckle Creek.

There is a great piece of moon rock in the visitors centre as well as lots of real objects from the early space missions. A real “must visit” for those interested in space and NASA.

AT&T’s Jamesburg Dish Visit – by Robert Brand

Jamesburg Visit

In early June 2012 I visited the Jamesburg site with the intention of surveying the site and turning it into a data centre. The site was abandoned by AT&T in 2002 following the attacks on the NY World Trade Center buildings. It was thought by AT&T that Jamesburg was too vulnerable to aircraft attack of a similar nature. I recently set up a company that is now looking to buy the site. The 2 day Jamesburg visit was like a trip back in time as many of the site’s offices and systems were still fully intact.

The picture above shows that the dish is still able to move as it was taken out of stow for a movie being made on site at the time of my visit. The large vertical appendage on the left of the structure is a covered stairway giving access to the upper rooms. Although the tracking system is still installed, the owner was using a manual controller. The tracking system is shown below (Note you can click on the images to enlarge them):

The halls are still filled with pictures of the Intelsat family that was worked by Jamesburg and the battery room still filled with batteries:

The power switchboard is also 100% active and capable of switching half a megawatt.

Below is the current owner (Jeff Bullis – r) with his nephew (Scotty – l) in the lunchroom as it was when it was vacated – fully operational and well appointed. I am in the picture on the right with the rather interesting map with 2 Australias. One showing the pacific Intelsat coverage and the other showing the Indian Ocean Intelsat coverage.

The site had a room filled with filling cabinets with every bit of AT&T correspondence. A Jamesburg fax cover sheet is seen below (left). The waveguide below the dish is able to swivel and transition from the vertical to the horizontal in the photo to the right.

I certainly remember working with Jamesburg regularly on day shift as the morning US TV news feed was sent to Paddington from Moree. It is amazing to think that this site was so completely abandoned 10 years ago. It is like using a time machine to go back to when it was operational. An amazing experience   More on Jamesburg in a future post.

World Moon Bounce – Part 1 (Archives)

World Moon Bounce 2009 & 2010 – Part 1

*** Retrieved from Archives ***

Robert BrandJust before the 40th Anniversary of Apollo 11 in 2009, I got contacted by a gentleman wanting to do a commemorative HAM radio event between the Jamesburg Earth Station and the Parkes Radio telescope. His name was Pat Barthelow. Moon Bounce is basically bouncing signals off the moon and back to earth and using big dishes to do the work. In the week before the Apollo 11 40th Anniversary (July 2009) dishes from all over the world took part in World Moon Bounce Day (WMBD) and it was a great success. Notably Jamesburg and Parkes never took part!

We had support locally from the Wireless Institute of Australia (WIA) and financial support from the OTVA to make this happen. Kids from all over the world took part in WMBD. We broke records with a 3mW transmission from the old NASA Orroral Valley dish (now in Tasmania with UTAS) and a dish in the Netherlands – both 30m dishes. The data was successfully decoded and a new record set. The gain in these dishes is massive – about 60dB each for the technical. It is great to think that the gains of dirt on the surface of the moon where shaking ever so slightly and reflecting back the voices of children for a global hookup.

The story of World Moon Bounce Day and the 2010 World Moon Bounce event is below and taken from the Echoes of Apollo Website. The 2010 event turned more into a week long event as my partner in crime in the US – Pat Barthelow – managed to secure the Aricebo Dish for a week or so! This was written before the 2010 event:

World Moon Bounce Events:

World Moon Bounce Day Logo 2010

EOA April 17th 2010

This major event will add a new word to most people’s vocabulary – Moon Bounce. Moon Bounce has been happening for almost as long as the oldest of us can remember. From the early days when it was thought to be a  means of communications that the military could exploit right through to today’s more peaceful use by amateur radio hobbyists. So what is moon bounce? Also known technically as Earth-Moon-Earth transmissions (EME), it is simply bouncing radio waves off the moon’s surface and back to earth. Every day hundreds of people enjoy doing just that and they do it as everyday people using mainly homemade dishes and antennas and  a mix of “do it yourself” systems, electronics and “off the shelf” equipment.

So why hold World Moon Bounce Day? At Echoes of Apollo we are both interested in space (especially the moon) and amateur radio. We created an event to highlight both of these amazing areas of interest. We are also looking to the commercial world to take part soon and make this an event for the whole world to enjoy

On Saturday, April 17th, many of the world’s large parabolic antennas (sometimes called dishes) along with hundreds of amateur radio operators and their gear will stop their normal work and swing around to track the moon when it rises. Volunteers will then use the EME or Moon Bounce transmissions to link up with other dishes and antennas worldwide via the moon. Signals are literally being bounced off the moon’s surface and back to other stations on earth where they are received some 2.5 seconds later. Yes, at an atomic level we are actually shaking each atom on the moon’s surface every so slightly and they then radiate the signal back into space and to earth where we again use our high gain antennas and dishes to receive them

moon_bounce

The sites will be run by volunteers from the amateur radio community and they will be helping local youth talk to other youth from around the world in a “Jamboree of the Air” style event. This type of activity has happened before but never on this scale. One  fantastic demonstration was a small Moon Bounce occurred in 2007  to celebrate the UK’s Jodrell Bank Telescope’s 50th anniversary generated press and TV coverage. Children read and listened to their poetry being bounced of the moon. Jodrell Bank held another event in 2009, but it was a small event with a local transmitter.

The first World Moon Bounce Day held in June 2009 was huge by comparison with much high voice quality in comparison given the sizes of the big dishes at both ends that were involved. The bigger they are, the more effective power they will radiate and also the more power they gather and concentrate for reception.

Web video of World Moon Bounce Day on June 27th will be available on this website with feeds from multiple sites, so you can see all the action taking place. We have invited some of the world’s biggest dishes an a wealth of important people. We already have several large antennas taking part and we will provide a list shortly.

Why April 17th 2010?

At Echoes of Apollo we celebrate the amazing achievements of the Apollo astronauts and their vast numbers of support staff, whether part of the rocket design team, mission control or NASA‘s global communications network. We simply have the most incredible team ever assembled with a single goal that was beyond anyones expertise at the time of its announcement 10 years earlier. We celebrated the 40th anniversary of Apollo 11 with out first annual World Moon Bounce Day and this year we will be honoring Apollo 13′s return to earth 40 years earlier. Echoes of Apollo still believe that this mission was one of the most amazing and riveting stories of the space age. It is the only Hollywood movie made of any of he Apollo missions.

Arecibo Puerto Rico

This year, April 16,17,18, Echoes of Apollo Moon Bounce, a fun, educational, science outreach activity, will conduct 2 way Voice communications by bouncing radio signals off the Moon.  One day of the event, Saturday, the 17th, has been assigned the Moniker, “World Moon Bounce Day”.  Commonly known among the specialist amateur radio operators (hams) that do this,  as EME, for Earth-Moon- Earth,  this time, the Echoes of Apollo Moon Bounce event is quite special, and opens a big door of opportunity for Science outreach.The Arecibo Observatory amateur radio club has built an amateur radio EME station at the Arecibo 1000 ft dish.  Angel Vazquez, club president, is working with his team of radio amateurs and have produced a 500 watt station that will operate in the 70cm band, on 432.045 mhz.  The 500 watts at the feed of 58 dbi gain dish will produce a very loud signal that will be bounced from the moon, and can be heard, using very modest antennas.

On March 19, and 22, Arecibo conducted a test of their station on the air, establishing 2 way Moon Bounce contact with many ham radio operators all over the world.  The test, established that the very strong return signals from the moon, can be picked up, using radio communications receivers capable receiving 432.045 MHz  SSB and/or CW signals, and equipped with small, yagi antennas.

As a science/Education  outreach activity,  EOA  co founder, Pat Barthelow, has arranged for amateur radio mentors, and teachers, to supervise the construction of very simple, cheap yagi antennas that can be used to hear the moon bounced signals, returned to earth.  The yagi antennas are easy and cheap to build, according to published designs, and made from wooden  1 x 2 sticks, about 3-6 feet long, and welding rod,copper or aluminum wire.

The Massachusetts Institute of Technology Dishes at their Haystack facility. MIT based  Radio Amateurs are anticipated to be active with MIT station setup and operating.

The world wide event,  will have different stations around the world communicating whenever the moon is visible between them, and in the case of Arecibo, there will be two hour windows of operations, each of the three scheduled days. Arecibo only has limited time viewing the moon due the limited “steering” of about 20 degrees

On this weekend, this translates to operating times from Arecibo of:

Apr 16 1645 – 1930 UTC

Apr 17 1740 – 2020 UTC

Apr 18 1840 – 2125 UTC

Greetings from Switzerland via the moon

Kids talking via the moon for World Moon Bounce Day.

“First of all many Thanks to all who helped us talking to our non Radio Amateurs, Visitors and Children of course. Special Thanks to Dough VK3UM how had to answer many questions about his “Crocodile” in his shack :-)

More than 300 Visitors, many Families, Swiss Television, News Journalists, joined our outstanding Party.

We also had ON4BCB, Walter on board and many Swiss Radio Amateurs and youngest YL too. 45 Children took this chance to send a short Message to the Moon. And a few did a great job and learned very quickly how we communicate. Who knows maybe one of them will become Hamsone day  too… Swiss Television will report from EoA HB9MOON on Monday evening during Prime-time! It was an unforgettable event for us!

Christoph, HB9HAL / HB9MOON

The following is Swiss TV coverage of the Echoes of apollo event on World Moon Bounce Day 2009:

Our June 2009 event featured Apollo astronaut Bill Anders who reportedly had a great time talking to the world via the moon. We are hoping to have an even bigger lineup of guests and they will be featured in interviews with the Echoes team after the event. You will be able to listen to the broadcast via the moon on the Internet. We have some large dishes taking part and that announcement will be coming soon so please stand by for more information. Echoes of Apollo salutes all the amateur radio operators that make this event possible.

Is There any Science Being Done?

Yes, plenty. Even setting this gear up is a major challenge to get it right. Not only do many of the scientist that take part find the effort rewarding, they all find that they learn a lot from working with amateur radio operators. The staff at the Mt Pleasant dish (above) also broke world records during our 2009 event sending data to the moon and having received as viable data in the Netherlands and their transmitter was only 3 milliwatts – about 1/1000th the power of a bright incandescent flashlight. The gain and accuracy of big dishes can achieve some amazing results.

What Frequencies will be used?

Any frequency that operators can legally utilise. Most amateur radio operators will be using frequencies of about 1.3GHz which is almost half that used in microwave ovens and Wireless computer networks. This frequency is the best for bouncing signals off the Moon’s surface. Some possible commercial operator may use frequencies as high as 12GHz.

World Moon Bounce Day 2009

Below is some of the article on the Echoes of Apollo World Moon Bounce Day. Much of the article was written by the University of Tasmania (UTAS) staff members Rex Moncur VK7MO and Justin Giles-Clark VK7TW for the Wireless Institute of Australia (WIA):

27 June 2009 was designated World Moon Bounce Day as an amateur radio contribution to the celebrations of the 40th anniversary of man’s first landing on the moon. The event was organized by Echoes of Apollo – a joint project between Pat Bathelow (US) and Robert Brand (Australia). Key to the success of the event was the contribution of the Overseas Telecommunications Veterans Association. (OTVA) A key objective was to involve and interest school children in science and amateur radio by allowing children to hear voices from the moon. The event was supplemented by amateur Earth Moon Earth (EME) stations all around the world and particularly those with SSB capability on 23 cm.

Within Australia the University of Tasmania agreed to take part using their 26 metre dish which was originally used by NASA in the Orroral Valley near Canberra between 1964-1985 after which it was gifted to the University and transported to Mt Pleasant, near Richmond in southern Tasmania. Our involvement was to provide amateur EME equipment, help set up and test the system and operate the station on the day. As it eventuated the availability of large dishes provided the opportunity to explore QRP EME at as low a level as possible and we are pleased to report completion of a JT65 EME contact between the University of Tasmania’s 26 metre dish and a Dutch 25 metre dish, PI9CAM, with the Tasmanian end running only three milliwatts.

Setting up the University of Tasmania dish

While Dr Jim Lovell of the University of Tasmania willingly offered their dish and the support of the site technician Eric Baynes (VK7BB) it was first necessary to consider what was practical. At our first meeting it became clear that transmitting any sort of high power as required for SSB would be out of the question as the dish is fitted with five extremely sensitive liquid helium cooled receivers working from 4 to 22 GHz. There is no protection for RF and we could not risk damage to these receivers which are involved in ongoing international research programs. Accordingly, the Echoes of Apollo team where advised that we would contribute to the event but as a receive station only.

The feeds and receivers for the 26 metre dish are mounted in a small feed cabin (a cube approximately two metres per side) behind a Teflon window approximately one metre in diameter. Within the cabin there is a remotely controlled three axis focus frame that allows the feeds and receivers to be moved into the correct focal position depending on which feed is in use. There is space for a two GHz non-cooled feed and receiver which fortunately was not required around the time of the Echoes of Apollo event and the University agreed that this could be removed and replaced with a 23 cm antenna. Because of space limitations it was decided to use a small three turn helical. There is over 100 metres of LDF-4-50 coax between the dish and the control building where we could operate and for this reason we decided to down-convert at the feed and receive on 144 MHz. Eric constructed a down-converter and the VK7MO EME station provided pre-amplifiers, 144 MHz receiver, GPS frequency reference, computer running WSJT and bandpass filters at 1296 MHz and 144 MHz to limit interference from microwave systems at the nearby Hobart airport.

A few weeks prior to the event tests were conducted with Dave VK2JDS, with JT65c signal levels much worse than expected at -9 dB and no prospect of copying SSB. A sun noise test gave around 18 dB compared to 27 to 28 dB determined with the VK3UM EME calculator. The time for testing was limited as this is an operational radio astronomy research facility but the system was gradually refined with additional pre-amps and filters and through adjusting levels at all stages – as well as resolving the occasional “Murphy” problem. Finally we decided that the helical feed must be the remaining limitation and did some estimates to see if a Septum feed and choke ring could be physically mounted. Initially it fouled other equipment but after a redesign of the mount is was successfully installed. In the end we achieved a sun noise of 25 dB which was within a few dB of what could be expected. Every time the system needed adjustment Eric had to don a safety harness and go up in a cherry picker .

The story above is part of the article in the Amateur Radio magazine, a publication of the Wireless Institute of Australia.

Much of the credit for the 2009 World Moon Bounce Day success can be directly attributed to the efforts of the OTVA and other exOTC staff. This has been a fantastic experience and we are looking to grow the 2010 World Moon Bounce Day to even great success. Yes, a world first for OTC staff involvement and a world record! Plenty of Australian amateur radio people got involved and were active bouncing their signals off the moon. I am Now organising the 2010 World Moon Bounce Day for early April. If you wish to help, feel free to raise your hand.

Jamesburg in a Movie (Archived)

Battleship (2012) uses Jamesburg Earth Station (graphically).

*** Retrieved from Archives ***Posted on by

My company is currently looking to buy Jamesburg Earth Station with a view of using it as part of a deep space network. Sure Jamesburg Earth Station is not the only dish with this design, there are two others. One still in use in South America and another somewhere in the US – possibly Alaska from memory. The identical AT&T sister dish on the east coast was demolished many years ago. Jamesburg, however is the most well photographed and documented of the remaining dishes and thus attracts attention.

Jamesburg in a Movie

I was watching a movie set in current times in Hawaii (Battleship) on the weekend and was surprised to see this very early dish design from 50 years ago being used to contact aliens from a distant star system. It was hard to concentrate on the movie each time the dish came into view on the screen. In fact there were three of these dishes on the island mountain top and all equipped with a very modern system to beam signals somehow to a relay satellite. Yes, the movie was technically unbelievable anyway, but this made it worse. It was also heart wrenching to see the three dishes explode at the end of the movie. Of course the dishes were graphically reproduced as were the explosions.

So how close was the reproduction. Well, extremely close. They added a box to the top of the subreflector quadropod and the base was a bit slimmer, but that was it. The staining was also identical, but emphasised in the movie. I doubt that we will ever see Ceduna, Moree or Carnarvon dishes in this way, but if one relic from the past can manage a resurrection, then who knows?

While I was visiting the Jamesburg site, a film crew was actually filming the dish for an iPad interactive game to be called “200 seconds” so we can expect to see it emerge again from the archives!

Here is a comparison and some shots from the movie:

Note that the structure on the right of the movie dish is on the original also, but obscured due to the angles

Queensland Spaceport on Brisbane Radio

Spenser_Howson on ABC RadioRobert on Radio 2 re: Queensland Spaceport

The last couple of days have been spent talking to people about the possibility of a Queensland Spaceport. This has come from some someone outside my company and it is about space recreational activities. The media seems hopeful to discuss the possibility of a Queensland Spaceport. Previously Queensland was discussed as a possible launch site for more traditional rockets. I was contacted by Spencer Howson of Australia’s ABC radio network to talk about this. I try to keep my distance from the recreational side of space and concentrate on the benefits of having a spaceport in this country. Spencer broadcasts the breakfast show on Brisbane local Radio.

There is plenty of discussion about Team Stellar and what Australia is doing to land a private mission on the Moon.

P.S. I forgot to mention Team Stellar’s name! Please mentally insert into the broadcast.

This has come from some someone outside my company and it is about space recreational activities. The media seems hopeful to discuss the possibility of a Queensland Spaceport. Previously Queensland was discussed as a possible launch site for more traditional rockets. I was contacted by Rebecca McLaren Australia’s ABC radio network to talk about this. I try to keep my distance from the recreational side of space and concentrate on the benefits of having a spaceport in this country. Rebecca broadcasts over regional Queensland.

There is plenty of discussion about Team Stellar and what Australia is doing to land a private mission on the Moon.

Fuzzy Logic Science Show

Jason and Robert Brand on Canberra Radio

In April 2013, Jason and Robert Brand joined with Rod Taylor, the host of Canberra’s science show, Fuzzy Logic, for an hour of chat about space and what we are doing here in Australia. Jason got to talk about his involvement with high altitude balloon flights. He even got to back announce one the musical interludes. He had just turned 11 a few days earlier.

I discussed everything from my early days supporting space missions like Apollo 11 and right through to my work with Team Stellar.

How to Use this Site

Robert brand 2013What is WotzUp all about?

The simplest answer is “hands on” space! The author, Robert Brand has been working on science and space projects for some time and is letting everyone ride along with the projects he is working on. Some are high altitude balloon missions like the UpLift series. Others are space missions like Team Stellar’s bid to get to the moon. Whatever the project, it will have a Project name.

My son Jason was 9 years old in 2011 when this site was formed and Jason is involved in many aspects of space. He take part in most balloon flights and recoveries. He is also Team Stellar’s Australian Student Representative. He obtained his Foundation HAM radio license at age 9 to help with balloon flights and recoveries.

We also use the term/category General for a variety of reasons such as housekeeping or articles of general interest or even articles not associated with a mission or project. Occasionally we will also have Featured articles. These are articles of some significance to any project. Simply I might want to draw your attention to a key event. These featured articles will appear on the front page when you first open the site.
