2007 In Spaceflight
The year 2007 contained several significant events in spaceflight, including a Chinese ASAT test, the launches of the US Phoenix and Dawn missions to study Mars and Asteroid belt respectively, Japan's Kaguya Lunar orbiter, and the first Chinese Lunar probe, Chang'e 1. The internationally accepted definition of a spaceflight is any flight which crosses the Kármán line, 100 kilometres above sea level. The first recorded spaceflight launch of the year occurred on 10 January, when a PSLV, launched from the Satish Dhawan Space Centre, placed four spacecraft into low Earth orbit. One of these spacecraft was SRE-1, which returned to Earth twelve days later, in the first Indian attempt to recover a satellite after re-entry. Several carrier rockets made their maiden flights in 2007; the PSLV-CA, Long March 3B/E, Shavit-2, Zenit-2M, Proton-M Enhanced. These were all modernised or upgraded versions of existing systems. The RS-24 missile also conducted its first launch, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SRE-1
The Space Capsule Recovery Experiment (SCRE or more commonly SRE or SRE-1) is an Indian experimental spacecraft which was launched at 03:53 UTC on January 10, 2007, from Sriharikota by the Indian Space Research Organisation (ISRO). The launch was conducted using the C7 launch of the PSLV rocket, along with three other satellites. It remained in orbit for 12 days before re-entering the Earth's atmosphere and splashing down into the Bay of Bengal at 04:16 UTC on January 22. Overview SRE-1 was designed to demonstrate the capability to recover an orbiting space capsule, and the technology of an orbiting platform for performing experiments in microgravity conditions. It was also intended to test reusable Thermal Protection System, navigation, guidance and control, hypersonic aero-thermodynamics, management of communication blackout, deceleration and flotation system and recovery operations.

Exploration Of The Moon
The physical exploration of the Moon began when '' Luna 2'', a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it. NASA's Apollo program was the only program to successfully land humans on the Moon, which it did six times. The first landing took place in 1969, when Apollo 11 astronauts Buzz Aldrin and Neil Armstrong placed scientific instruments and returned lunar samples to Earth. The first unmanned landing on the far side of the Moon was made by the Chinese spacecraft Chang'e 4 in early 2019, which s ...

Libertad 1
Libertad 1 ( en, Freedom 1) is a single CubeSat built by the Space Program of the Sergio Arboleda University in Colombia. It is the first Colombian satellite sent to orbit. It was launched aboard a Dnepr rocket on April 17, 2007 from the Baikonur Cosmodrome, Kazakhstan and became the first Colombian satellite to orbit the Earth. It used a telemetric payload to keep it in communication with the University. It was expected to have a 50-day lifespan, however news reports two years after it was launched stated the satellite was still working and sending information, passing over Colombia twice a day.

Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

RS-24
The RS-24 Yars (РС-24 Ярс– ракета стратегическая (strategic missile)) - modification 24) also known as RT-24 Yars or Topol'-MR (russian: PC-24 «Ярс», NATO reporting name: SS-29 or SS-27 Mod 2) is a Russian MIRV-equipped, thermonuclear armed intercontinental ballistic missile first tested on May 29, 2007, after a secret military R&D project. It is essentially the same missile as the Topol-M except the payload “bus” has been modified to carry multiple independently targetable warheads (MIRV). Each missile is thought to be able to carry up to 4 warheads, although there is uncertainty about what the maximum capacity is. RS-24 is a missile that is heavier than the current RT-2PM2 Topol-M, and which some reports say can carry up to 10 independently targetable warheads. The 2007 tests were publicized as a response to the missile shield that the United States were planning to deploy in Europe. The RS-24 has been deployed operationally since 2010, w ...

Atmospheric Re-entry
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic speeds be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
