2. Lagrangian Points
... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

6. ASP: Star Science in the Autumn Sky
... In summer 1994, the biggest news in astronomy was the collision of comet Shoemaker-Levy 9 with Jupiter. During this school year, Jupiter will charge back into the limelight with the arrival of the Galileo spacecraft (see figure 8 ). On Dec. 7, following a tortuous six-year ramble through the solar system, Galileo will begin its two-year mission studying Jupiter and its gaggle of moons. ... Besides the camera, Galileo will carry instruments capable of identifying minerals on Jupiter's moons. ...

10. http://zebu.uoregon.edu/51peg.html
... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

13. A Graphical Planning and Scheduling Toolkit for Astronomical Spacecraft
... A small yet powerful planning and scheduling toolkit has been built for the Submillimeter Wave Astronomy Satellite ( SWAS ) Small Explorer spacecraft. ... The simple design, minimal resource requirements and easy extensibility of the SWAS planning and scheduling toolkit should make it useful for other space astronomy missions. ... The relatively severe time and manpower constraints for the development of the SWAS Planning and Scheduling toolkit have forced it to remain small and simple. ...

14. http://www.eso.org/public/news/eso1529/kids/
... Jupiter is our Solar System?s very own superhero. The giant planet is two and a half times more massive than all the rest of the planets in our Solar System combined. And with great mass, comes great gravity. With the power of super-strong gravity, Jupiter plays a heroic role in our Solar System, protecting life on Earth. ... Unfortunately, we have found lots of solar systems with massive planets that lie close to their star, but not so many that lie far away, like Jupiter. ...

16. http://www.mso.anu.edu.au/pfrancis/roleplay/MysteryPlanet/Orbits.doc
... The force F of gravity between two objects of mass m and M, whose centres are a distance r apart, is given by Newton's famous equation: [pic], where G = 6.67(10-11 N m2 kg-2, and F is measured in Newtons. So, the force in orbit Fo is weaker than the force on the Earth's surface F0 by the ratio: [pic] where the radius of the Earth is 6,400 km, and the orbit is 1000 km above the Earth's surface. ... Energy Considerations Another way to see all this is to consider the energy of an object in orbit. ...

18. System of zero gravity state on the spacecraft 'Photon M4'
... In spite of the fact that the orbit assumes a zero gravity (the scientists count on it by growing super-clean crystals and other materials impossible on the earth), in fact, none spacecraft provides such conditions. ... This question is answered by the device developed by SSAU scientists - Micro-acceleration Compensation Space System (MCSS). ...
