Record boost for ATV to raise ISS orbit

23.06.2008
For the second time since April, ESA's Jules Verne ATV was used to raise the orbit of the International Space Station yesterday. A record boost from the 20 minute burn of the Automated Transfer Vehicle's main engines successfully lifted the altitude of the 300-tonne Station by around 7 km to an altitude of around 345 km above the Earth's surface.

The Automated Transfer Vehicle (ATV) was prepared for reboost operations by ATV Control Centre (ATV-CC) in Toulouse, France. The manoeuvre started at 08:42 CEST (06:42 GMT) yesterday morning and provided a 4.05 m/s thrust lasting 20 minutes using two of the ATV's four main engines with an outstanding precision of 1%. While the automatic order was initiated by Moscow Control Centre, two dozen controllers from ESA, CNES and Astrium at ATV-CC closely monitored ATV's subsystems throughout the crucial manoeuvre.

"Today, Jules Verne ATV has again successfully demonstrated that it is able to perform this vital function on regular basis. Only Progress and ATV can provide this powerful reboost. We should have at least one more reboost in July and two in August," said Hervé Côme, ESA's ATV Mission Director at the ATV Control Centre in Toulouse, France.

Regular reboosts are needed to overcome the effects of residual atmospheric drag which makes the Station lose about 100 m in altitude per day.

This second main reboost manoeuvre comes after the first one performed on 25 April, which was less powerful with 2.6 m/s of thrust. Today’s reboost has consumed about 400 kg of propellant on board Jules Verne. During the reboost the three ISS crewmembers were busy with their daily activities and could not feel the very gentle acceleration given by the ATV.

Jules Verne ATV is scheduled to remain docked to the International Space Station until September. At the end of its mission, Jules Verne, loaded with up to 6.5 tonnes of material no longer required by the ISS, will undock and then burn up completely during a guided and controlled re-entry high over the Pacific Ocean.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
