Nanosat fleet proposed for voyage to 300 asteroids

Nanosat fleet proposed for voyage to 300 asteroids

A fleet of tiny spacecraft could visit over 300 asteroids in just over three years, according to a mission study led by the Finnish Meteorological Institute. The Asteroid Touring Nanosat Fleet concept comprises 50 spacecraft propelled by innovative electric solar wind sails (E-sails) and equipped with instruments to take images and collect spectroscopic data on the composition of the asteroids. Each nanosat would visit six or seven asteroids before returning to Earth to deliver the data. The concept will be presented by Dr Pekka Janhunen at the European Planetary Science Congress (EPSC) 2017 in Riga on Tuesday 19th September.

“Asteroids are very diverse and, to date, we’ve only seen a small number at close range. To understand them better, we need to study a large number in situ. The only way to do this affordably is by using small spacecraft,” says Janhunen.

In the mission scenario, the nanosats flyby their target asteroids at a range of around 1000 kilometres. Each nanosat carries a 4-centimetre telescope capable of imaging the surface of asteroids with a resolution of 100 metres or better. An infrared spectrometer analyses spectral signatures in light reflected or emitted by the asteroid to determine its mineralogy. The instruments can be pointed at the target using two internal reaction wheels inside the nanosats.

“The nanosats could gather a great deal of information about the asteroids they encounter during their tour, including the overall size and shape, whether there are craters on the surface or dust, whether there are any moons, and whether the asteroids are primitive bodies or a rubble pile. They would also gather data on the chemical composition of surface features, such as whether the spectral signature of water is present,” says Janhunen.

E-sails make use of the solar wind – a stream of electrically charged particles emitted from the Sun – to generate efficient propulsion without need for propellant. Thrust is generated by the slow rotation of a tether, attached at one end to a main spacecraft carrying an electron emitter and a high-voltage source and at the other to a small remote unit. The spinning tether completes a rotation in about 50 minutes, tracing out a broad, shallow cone around a centre of mass close to the main spacecraft. By altering its orientation in relation to the solar wind, the nanosat can change thrust and direction.

The thrust generated by E-sails is small; a 5 kilogramme spacecraft with a 20-kilometre tether would give an acceleration of 1 millimetre per second at the distance of the Earth from the Sun. However, calculations show that, on top of the initial boost from launch, this is enough for the spacecraft to complete a tour through the asteroid belt and back to Earth in 3.2 years. Nanosatellites do not have the capacity for a large antenna, so the concept includes a final flyby of Earth to download the data. The overall mission would cost around 60 million Euros, including launch, giving a cost of about 200,000 Euros for each asteroid visited.

“The cost of a conventional, state-of-the-art mission to visit this number of asteroids could run into billions. This mission architecture, using a fleet of nanosats and innovative propulsion, would reduce the cost to just a few hundred thousand Euros per asteroid. Yet the value of the science gathered would be immense,” says Janhunen.

Hypersonic flight: Threat or opportunity?

If there's one word that keeps military planners from sleeping at night, it's "hypersonic." The ability to fly at more than five times the speed of sound holds the promise of getting to the antipodes in less time than it takes to drive across town. However, it also makes possible deadly weapons that can penetrate any defenses currently available while delivering the destructive force of a tactical nuclear weapon. So what is hypersonic flight and is its development an opportunity or a threat? Continue reading... http://newatlas.com/hypersonic-flight/50801/

Irkut Corporation starts the second stage of MC-21 flight tests

On September 13, the second stage of MC-21-300 in-plant development tests program has begun. The modified airplane systems worked without complaint during the flight. The flight lasted about 2 hours.

In the course of preparations for the second stage of MC-21-300 tests strain gauges have been mounted on the aircraft. They allow to accurately measure loads on the structure. Also by the results of the first flight test stage the software has been corrected.

The main goal of this stage of testing is to extend the range of flights by mass, centering, speed and altitude.


Airbus encourages Northern Ireland’s SMEs to look to Space for new business opportunities

Guildford, 18 September 2017 – Airbus Defence and Space in partnership with Digital Catapult NI, Invest Northern Ireland and the Northern Ireland Space Office launches a new space challenge to encourage Northern Ireland small and medium-sized enterprises and research institutions to generate new business opportunities using satellite imagery. The development of these new applications can range e.g. from fishing and farming to urban planning and traffic management, and should contribute to a sustainable society. The winner will be allowed to secure satellite imagery worth €20,000 from Airbus-owned or operated Earth observation satellite systems.

This initiative aligns to the Northern Ireland Space Sector Strategy, launched in October 2016 which set a vision to develop Northern Ireland as a globally recognised region for space sector innovation and creativity. Thus it perfectly fits with the Airbus’ strategy to extend its digital ecosystem through programs like the “Global Earth Observation Challenge” launched in May 2017.

“As leading Space Company, we have an essential role to play in the promotion of satellite benefits to non-space communities to highlight how we can provide support to current societal challenges and uncover viable business opportunities for SMEs” said François Lombard, Head of the Intelligence Business Cluster at Airbus Defence and Space.

Welcoming the initiative, Bill Montgomery, Invest NI’s Director of Advanced Manufacturing & Engineering said: “Airbus’ space challenge offers many different types of business the opportunity to scope out growth areas for their business using data from satellites. The UK Space Agency projects the global space related market to be worth €440bn by 2030 and Invest NI is working to help ensure Northern Ireland companies, academia and those with related interests in the Space Sector share in the growth opportunities.”

Transport Canada proposes UAV regulatory overhaul - key amendments and expected impact: are you ready?

Many drones are more accessible than ever; they are relatively inexpensive, require little or no assembly, and are relatively easy to fly. This makes drones an attractive option for many businesses and industries. However, the dramatic increase in users who lack familiarity with the rules and regulations surrounding the safe operation of and permitted use of drones has led to numerous drone-related incidents. This has caught the attention of Transport Canada. Continue reading https://www.lexology.com/library/detail.aspx?g=4a544ea5-4bcd-40e3-b404-a8aae5c601b7


Canada, Kongsberg to develop drone emergency management system


“Securing and managing the airspace around disaster scenes or at big public events is becoming a real concern for all levels of government,” said Paige Cutland, IRIS program director for Kongsberg Geospatial. “Even if a drone operator isn’t acting with malicious intent, they have the potential to cause considerable harm if, for example, they fly into the path of an air ambulance. We need effective tools to help prevent this while also allowing legitimate UAV operations to be safely integrated into the emergency airspace. ”
