Double Star |
| Double Star is the first mission launched by China to explore the Earth's magnetosphere - the magnetic bubble that surrounds our planet. The mission involves two satellites - TC-1 and TC-2 - each designed, developed, launched, and operated by the Chinese National Space Administration (CNSA). It is planned to synchronise the two Double Star orbits with those of ESA's four Cluster satellites so that all six spacecraft are studying the same region of near-Earth space at the same time. This orbital configuration will enable scientists to obtain simultaneous data on the changing magnetic field and population of electrified particles in different regions of the magnetosphere. |

GRACE |
| GRACE 1 and GRACE 2 are a pair of American-German (NASA-DLR) identical satellites launched on March 17, 2002. The acronym stands for Gravity Recovery And Climate Experiment. The satellites were developed to provide detailed measurements of Earth's gravity field that help scientists better understand the effects gravity has on Earth's global climate change. GRACE monitors the mass and location of water as it moves around on the surface of the Earth, cycling between the land, oceans, and polar ice caps. |

Mars Odyssey |
| The $300 million Mars Odyssey should become the first spacecraft to visit
Mars since two disastrous failures in 1999. The orbiter was launched on
April 7, 2001 and should reach Mars on October 24, the same year. Odyssey
will collect images that will be used to identify the minerals present in the soils
and rocks on the surface. NASA is hoping that the information collected will
give clues to the planet's climate history and help determine whether life
has ever existed on the Martian surface. The craft carries a suite of
scientific instruments designed to analyse, from orbit, the composition of
the Martian surface, and provide vital information about potential
radiation hazards for future human explorers. During and after its science
mission, the Odyssey orbiter will also support other missions in the Mars
Exploration program. It will provide the communications relay for U.S. and
international landers, including the next mission in NASA\'s Mars Program,
the Mars Exploration Rovers to be launched in 2003. Scientists and
engineers will also use Odyssey data to identify potential landing sites
for future Mars missions.

METEOSAT |
| The series of meteorological satellites METEOSAT became the first European application program in the space. Since the launch of METEOSAT-1 on November 23, 1977 seven satellites were inserted into a geostationary orbit. Being on this orbit a satellite is located always above the same point of the earth surface, because the satellite's orbital period is equal to 24 hours there, and the orbit's inclination to the geoequator is zero. Three satellites METEOSAT are at present operational: |
| |
|
|
GOES |
| There are normally two US meteorological satellites, GOES-EAST and GOES-WEST, in geostationary orbit over the equator. The former monitors North and South America and most of the Atlantic Ocean, and the latter surveys North America and the Pacific Ocean basin. This program operates for 25 years already, and today it is one of the leading world services for the weather forecasting. The two satellites observe about 60 percent of the Earth's surface at each moment and send images of the upcoming hurricanes, thunderstorms, snowfalls, and just clouds to meteorologists at NOAA (the National Oceanic and Atmospheric Administration). The satellites are occasionally exchanged with new ones on expiry of their life-time or failures. Look at this pair. |

Cassini |
| Now it's good time to download to RedShift the interplanetary orbit of Cassini spacecraft, a joint project of NASA, European Space Agency and Italian Space Agency. This probe was launched about two years ago to study the ringed planet Saturn and its mysterious satellite Titan, but in summer 1999 it came back! On August 18, 1999 the spacecraft passed just 1,2 thousands kilometers from the Earth's surface to perform a so-called "swing-by" maneuver, where the gravity field of our planet, like a giant sling, accelerated Cassini on its long way to the far planet. Earlier, two Venus swing-by were executed and another - Jupiter Swing-by– is scheduled at the end of 2000. This is an excellent scheme of interplanetary flight which saves much fuel ("delta V") and thus allows charging the spacecraft with more scientific payload. Place yourself on the spacecraft which approaches either Venus or Earth, or, at last, Saturn, then lock the target planet as the , and enjoy the fantastic view of a swing-by! Here the Cassini's orbit at different parts of its flight is (ref: JPL data): |

Planet-B |
| Japanese Planet-B ("Nozomi") mission to Mars began on July 4, 1998. It is designed to study the Martian upper atmosphere and magnetic field of the Red planet. The spacecraft was initially scheduled to reach Mars in 10 months after the launch, but during the trajectory correction maneuver (TCM) on December 20, 1998 a technical problem did not allow to execute the maneuver properly. As a result, it became impossible to perform the initial navigational plan, and it has been changed to minimize the further consumption of fuel rest aboard the spacecraft. The new mission profile developed "in real time" by flight dynamics engineers from ISAS (Sagamaihara, Japan) includes two close approaches of Planet-B to Earth (swing-by) and use of the planet's gravity for "free" accelerating the spacecraft. However, such a reduced fare leads to delay of the spacecraft arrival at Mars till the beginning of 2004. Here the new flight scheme of Planet-B is (ref: ISAS solution): |

Stardust |
| Stardust spacecraft launched on February 7, 1999 is the first mission to bring back some material from beyond the Moon. The main goal of the mission is to encounter with comet Wild 2 at a low velocity (6.1 km/s), collect samples of the comet medium and deliver them to the Earth. The flight trajectory is unusual to ensure low cost of the mission. The spacecraft circles the Sun two times before reaching the comet on January 2, 2004 and returns to us at the end of the third loop, on January 15, 2006. Check this fantastic flight yourselves and enjoy the RedShift views of encounter with Wild 2 and approach to the Earth! (Ref: NAV JPL solution at NAIF JPL). |

Mars Climate Orbiter |
| About every two years there is a launch opportunity for missions to Mars. During the December 1998-January 1999 two spacecraft were launched to investigate the Red Planet and its environment. The main goal of the first mission, Mars Climate Orbiter (MCO), was careful studying Martian atmosphere for about one Mars year (687 days). MCO should also provide relay support for the second spacecraft, Mars Polar Lander (MPL) and, likely, for future Mars missions. However, the spacecraft crashed on Mars just after arrival to that planet because of a control error… Mars Climate Orbiter was launched on December 11, 1998. Its interplanetary orbit was of so-called 2nd type, i.e., the spacecraft will take more than 180 degrees around the Sun. Several Trajectory Correction Maneuvers (TCM) will be applied to the MCO to get it to Mars. Download and check its orbit at different parts of its 9 1/2 months' (not "weeks"...) cruise from Earth to Mars (ref: NAV JPL solution at NAIF JPL). |

Mars Polar Lander |
| Mars Polar Lander was launched on January 3, 1999. It had to reach the Red planet in early December 1999, descend on the Martian surface not far from the planet's South pole (between 75 and 78S), and work there for 90 days, at least. However, like MCO the new probe was lost upon its arrival at Mars. What happens…? The cruise trajectory of MPL is as follows: |

NEAR |
| At the very beginning of 1999 the spacecraft NEAR (Near Earth Asteroid Rendezvous) had to reach the main goal of the mission - asteroid 433 Eros. For the first time in the history of deep space exploration a spacecraft would follow a minor planet over more than one year and study it at extremely close distance (up to few dozens km from the asteroid surface). Unfortunately, on December 20, 1998, just 21 days before the scheduled rendezvous with asteroid Eros, NEAR failed to complete a crucial engine burn and ... NEAR and Eros are now traveling in nearly identical orbits around the Sun but not together. During its cruise the spacecraft flew by another asteroid 253 Mathilde on June 27, 1997 and by the Earth on January 23, 1998. Upload and check the orbit of the spacecraft for its about four years' voyage towards Eros (ref: APL JHU solution of 12/08/1998, JPL solution # 51). |

Telstar 18 (APStar 5) |
Telstar 18 (APStar 5) is an American communications spacecraft that was launched by a Zenit 3SL rocket from the Odyssey platform floating on the equatorial Pacific Ocean on 29 June 2004. It was intended to be a geostationary satellite, but due to the premature stoppage of the boost from the final DM-SL stage, it ended far below the geostationary orbit - an apogee of only 21000 km instead of 36000 km. First analysis showed, that the spacecraft can be put into a geostationary orbit by its thrusters, possibly even without reduced lifetime. Telstar 18 will replace the aging APStar 1 satellite. It will provide voice, video and data services to China, Hawaii, and East Asia. The new satellite will also be used to provide space-based Internet backbone services for the main cities of Asia to and from the U.S. through Hawaii.
