ARISS contact planned with technical college in Poland

On Saturday February 4, 2012 at approximately 12.41 UTC, which is 13.41 CEWT, an educational ARISS contact is planned with the Polytechnic school in Walbrzych, Poland. Amateur radio station W6SRJ, located in California, will operate the contact.

The Polytechnic school in Walbrzych has been established in 1946.
These days it is well known as Secondary Complex School “Energetyk”, with a population of over 900 students. They study electricity, electro-mechanics, electronics, technical graphics, telecommunications, IT and ITC techniques, advertising. The school is equipped for students with disabilities, education is on a very high-level and graduate students can easily find employment. It is the best technical school in Walbrzych.

Apart from teaching, the school offers many other activities.
The Shooting section exists since sixty years and takes leading positions in “The Silver Muskets” contest. Since three years, students take part in the Robotic Group, acquiring knowledge and having a lot of fun, building robots from scratch, according to their own ideas and knowledge. They were several times among the winners in prestigious competitions on an International level. There is also the school band “Underland”. The band is well-known in Walbrzych for they perform many concerts, in the city and around. In school is also active in “Energol TV” and they produce a newspaper “Alcatraz 2”.

The amateur radio club SP6PBA is located in the school. Besides HF communications with HAM operators all over the World, the club also transmits HAM TV in the 1.2 GHz band.

The ARISS contact will be conducted in English. It will be broadcast on EchoLink AMSAT (node 101 377) and JK1ZRW (node 277 208) Conference servers, as well as on IRLP Discovery Reflector 9010.

Students will ask as many of the following questions as time allows.
1. Lukasz (18): What is the difference between an astronaut and a cosmonaut?
2. Kacper (16): How does it feel to be weightless?
3. Karol (20): How long does it take to get accustomed to gravity after returning to Earth from the ISS?

UK Space Agency to send up first satellite

Artist impression of UKube-1

The UK Space Agency has announced plans to launch its first satellite – if it can find the right spaceship to catch a lift from.

The tiny UKube-1 will carry a variety of scientific experiments when it eventually gets off the ground later this year.

 

The project will see the agency take a leap into launching cubesats – a type of relatively cheap, mini-satellite for space research which has a volume of little more than one litre, a mass of around 1.3kg.

It also marks a significant departure for UKSA, formed less than a year ago from the British National Space Centre, which had focused on supplying European Space Agency with parts and expertise for a variety of missions. 

Head of communications Matt Goodman said: ‘We’re still in discussions with potential launch providers for UKube-1, and are working hard to find a launch option for the satellite.

‘Since cubesats tend to “piggy-back” on larger payloads during a launch, finding an opportunity with the right orbital configuration is not straightforward.’

Despite its relatively small budget, UKSA hopes to become a much bigger player in the industry, launching several more satellites in the years to come.

Agency head David Williams said: ‘The idea of cubesat is that we see it as a series with a launch every year or maybe two years allowing the sort of people that wouldn’t normally get access to space to run experiments in it.

‘We’d like to see this being an ongoing programme because it gives university groups, and even school groups and amateur groups, the opportunity to test fly equipment. It also gives industry the opportunity to test fly and to develop ideas on bits and pieces of electronics.’

UKSA is also involved in another ambitious project named Skylon, which is an ‘unpiloted, reusable spaceplane intended to provide inexpensive and reliable access to space’, according to the British firm Reaction Engines, which is hoping to build the new craft. 

The project got the green light from the European Space Agency in May last year. Although technologically possible, the project’s major stumbling block appears to be cost.

Mr Williams said: ‘We’re trying to work with [the team] to work out how they can raise the necessary finance and whether government should have any involvement in it in the future.

‘It’s going to be an expensive programme, several billion pounds over quite a long period, and the question is which industries wish to be involved, how UK should it be, how European should it be, should it be an international project?’ he added. ‘The idea of a true single-stage-to-orbit plane is very novel.’

Vega Satellite Launch Vehicle

The Vega (Vettore Europeo di Generazione Avanzata) is a new-generation launch vehicle being developed jointly by the Italian Space Agency (ASI) and the European Space Agency (ESA) for Arianespace.

Vega is named after the second brightest star in the northern hemisphere.

The Vega is a small launcher which can place small to medium-sized satellites into the polar and low-earth orbits. The launch vehicle complements the heavy Ariane 5 and medium Soyuz rockets launched from French Guiana.

Vega development programme history

“The Vega is a small launcher which can place small to medium-sized satellites into the polar and low-earth orbits.”

The development of the Vega launcher commenced under the Vega programme in 1998. The programme is being funded by Italy (65%), France (12.43%), Spain (5%), Belgium (5.63%), the Netherlands (3.5%), Switzerland (1.34%) and Sweden (0.8%).

Vega’s main engine P80 rocket motor was successfully tested in December 2007. The test campaign of the Vega launch vehicle commenced in November 2010.

The test phase validated the operational readiness of the launch vehicle and ground station components. The assembly of the new Vega launcher was completed in February 2011.

The first launch is scheduled for February 2012 from Europe’s Spaceport in French Guiana. ESA plans to launch its IXV (intermediate eXperimental vehicle) aboard Vega in 2014.

The marketing activities will commence after the first launch. Arianespace plans to increase the launch frequency from two to four each year.

Contractors

ASI and Avio have established a new 30-70 partnership called Elv for the programme. ESA and Elv signed the Vega development contract in February 2003.

Elv, as the prime contractor, is responsible for the management of the Vega programme. The company also coordinates the activities of the subcontractors involved. Arianespace provides support services for the qualification and combined test campaign of the rocket.

In December 2011, ESA and the Arianespace signed a contract to study the launch of Vega under the Verta (Vega Research and Technology Accompaniment) programme. The programme will test and qualify new vital technologies for future re-entry vehicles.

Vega design

The Vega launch vehicle is designed to support various missions and payload configurations in order to meet different market requirements. It offers payload configurations from a single satellite to one primary satellite plus six micro-satellites.

“ASI and Avio have established a new 30-70 partnership called Elv for the programme. ESA and Elv signed the Vega development contract in February 2003.”

Vega can place multiple payloads into orbit which is uncommon with most small launchers. It can carry payloads of 300kg to 2,500kg based on the type and altitude of the orbit required by the customers.

The vehicle has a length of 29.9m, a diameter of 3.025m and a typical lift-off mass of 137t.

The in-orbit launch capacity of the vehicle is 1,500kg into the polar orbit at an altitude of 700km. The single body launcher is incorporated with three solid propulsion stages and an AVUM (attitude vernier upper module).

The solid propellant motors, supplied by Avio, are covered by composite casing. The motors feature carbon epoxy filament wound casing and nozzle.

The first stage is powered by the P80 solid rocket motor. The second and third stages are powered by Zefiro 23 and Zefiro 9 motors respectively. The fourth stage AVUM consists of a UDMH / NTO bipropellant main engine with re-ignition capability and cold gas attitude control system.

Vega launch facilities

The Vega will be launched from ZLV launch complex at Kourou, French Guiana. Based on the ELA-1 (Ensemble de Lancement Ariane No. 1) launch complex, the site was originally used for the Ariane 1 and Ariane 3 vehicles.

The existing facilities, such as the launch pad, mobile gantry and infrastructure, were upgraded for the launch of the Vega.

The original flame ducts of the launch pad were retained. They will transfer exhaust gases during ignition and lift-off of the Vega.

The power and environmental control connections to the launcher and its payloads are provided by a new fixed umbilical mast. Four tall towers erected around the launch table will provide protection against lightning strikes.

The renovated mobile gantry provides provides ideal working conditions to the personnel during the launch vehicle assembly and payload integration.

The operational control centre for the Vega will be within the Spaceport’s Control Centre no. 3 (CDL 3) facility, which is used for Ariane 5 missions. The centre incorporates independent operational control and monitoring systems. The Vega facility will share resources with the ongoing Ariane 5 mission as it is co-located in the CDL-3 building.
