July 31, 2013 by Pete Harding International Space Station (ISS) program managers and engineers are working on long-term plans to support future crew and cargo vehicles, including the installation of a new docking system onto the station for use by future commercial crew vehicles, along with the relocation of some Station modules, in order to free up ports for use by future crew and cargo spacecraft. New ISS docking system:

Cool Science Experiments for Kids | Grape + Microwave = Plasma Fireworks 11,941 views 6 months ago Put a grape in the microwave and watch it become plasma fireworks. When you cut a grape ALMOST in half, and put it in the microwave, it will create plasma and make an awesome reaction. Step 1: Put a grape on a ceramic plate Step 2: Cute the grape almost in half.
The Large Hadron Collider
The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum. They are guided around the accelerator ring by a strong magnetic field maintained by superconducting electromagnets.
Exploration Flight Test 1
Overview[edit] The spacecraft will remain attached to the Delta IV's Upper Stage until reentry begins and will rely on internal batteries for power rather than photovoltaic arrays, which will not be installed.[3] The flight is intended to test various Orion systems, including avionics, heat shielding and parachutes prior to its debut launch aboard the Space Launch System, currently scheduled for late 2017.[4] EFT-1 Orion is being built by Lockheed Martin.[5] On June 22, 2012, the final welds of the EFT-1 Orion were completed at the Michoud Assembly Facility in New Orleans, Louisiana.[5] It was then transported to Kennedy Space Center's Operations and Checkout Building, which is where the remainder of the spacecraft will be completed.[6] Data gathered from the test flight will be analyzed by the Critical Design Review (CDR) in April, 2015.[7] After splashdown in the Pacific Ocean, crews will recover the EFT-1 Orion crew vehicle and outfit the capsule for an ascent abort test.[8]

World Magnetic Model Calculator
Use the tool below to compute values for the geomagnetic field and secular variation for a given set of coordinates and date. This calculator uses the World Magnetic Model as released in Dec 2019. Choose the geodetic latitude and longitude either by entering the coordinates into the form below (decimal degrees may be entered into the 'degrees' field, and degrees S or W should be entered with a negative sign), or by simply clicking the location on the map.
Astronomie - MESSENGER arrive aux abords de Mercure - AstroSurf
Envoyé 03-01-2008 19:42 j'ai relevé ces precisions sur le site, où il s'avère que c'est bien pour diminuer la vitesse de la sonde afin qu'elle soit capturée par Mercure...Mais ça ne répond pas tout à fait à la question : pourquoi peut-on envoyer directement une sonde en orbite de Mars et pas de Mercure ? Rôle joué par le Soleil, faible masse de Mercure ?? "5. Why take such a long and complex route to Mercury?

Pulsar Sounds (Jodrell Bank Observatory)
A pulsar is a highly magnetised neutron star, with a radius of 10-15 km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km. Radiation is beamed out along the magnetic poles and pulses of radiation are received as the beam crosses the Earth, in the same manner as the beam from a lighthouse causes flashes. Being enormous cosmic flywheels with a tick attached, they make some of the best clocks known to mankind. The sounds on this web page directly correspond to the radio-waves emitted by the brightest pulsars in the sky as received by some of the largest radio telescopes in the world. To listen to the pulses of a radio pulsar, click on the sound icons below.

Have you ever asked “what is beyond the edge of the universe?” And have you ever been told that an infinite universe that has no edge? You were told wrong. In a sense. We can define a boundary to an infinite universe, at least mathematically. And it turns out that boundary may be as real or even more real than the universe it contains.
