An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation from orbit, similar to spy satellites but intended for non-military uses such as environmental monitoring, map making etc. The first occurrence of satellite remote sensing can be dated to the launch of the first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957. Sputnik 1 sent back radio signals. NASA launched the first American satellite, Explorer 1, in January 31, 1958; the information sent back from its radiation detector led to the discovery of the Earth's Van Allen radiation belts. The TIROS-1 spacecraft, launched on April 1, 1960 as part of NASA's TIROS Program, sent back the first television footage of weather patterns to be taken from space; as of 2008, more than 150 Earth observation satellites were in orbit, recording data with both passive and active sensors and acquiring more than 10 terabits of data daily. Most Earth observation satellites carry instruments that should be operated at a low altitude.
Altitudes below 500-600 kilometers are in general avoided, because of the significant air-drag at such low altitudes making frequent orbit reboost maneuvres necessary. The Earth observation satellites ERS-1, ERS-2 and Envisat of European Space Agency as well as the MetOp spacecraft of EUMETSAT are all operated at altitudes of about 800 km; the Proba-1, Proba-2 and SMOS spacecraft of European Space Agency are observing the Earth from an altitude of about 700 km. The Earth observation satellites of UAE, DubaiSat-1 & DubaiSat-2 are placed in Low Earth Orbits orbits and providing satellite imagery of various parts of the Earth. To get global coverage with a low orbit it must be a polar orbit or nearly so. A low orbit will have an orbital period of 100 minutes and the Earth will rotate around its polar axis with about 25 deg between successive orbits, with the result that the ground track is shifted towards west with these 25 deg in longitude. Most are in Sun-synchronous orbits. Spacecraft carrying instruments for which an altitude of 36000 km is suitable sometimes use a geostationary orbit.
Such an orbit allows uninterrupted coverage of more than 1/3 of the Earth. Three geostationary spacecraft at longitudes separated with 120 deg can cover the whole Earth except the extreme polar regions; this type of orbit is used for meteorological satellites. Herman Potočnik explored the idea of using orbiting spacecraft for detailed peaceful and military observation of the ground in his 1928 book, The Problem of Space Travel, he described. The book described geostationary satellites and discussed communication between them and the ground using radio, but fell short of the idea of using satellites for mass broadcasting and as telecommunications relays. A weather satellite is a type of satellite, used to monitor the weather and climate of the Earth; these meteorological satellites, see more than clouds and cloud systems. City lights, effects of pollution, auroras and dust storms, snow cover, ice mapping, boundaries of ocean currents, energy flows, etc. are other types of environmental information collected using weather satellites.
Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have been monitored. Other environmental satellites can assist environmental monitoring by detecting changes in the Earth's vegetation, atmospheric trace gas content, sea state, ocean color, ice fields. By monitoring vegetation changes over time, droughts can be monitored by comparing the current vegetation state to its long term average. For example, the 2002 oil spill off the northwest coast of Spain was watched by the European ENVISAT, though not a weather satellite, flies an instrument which can see changes in the sea surface. Anthropogenic emissions can be monitored by evaluating data of tropospheric NO2 and SO2; these types of satellites are always in Sun synchronous and "frozen" orbits. The Sun synchronous orbit is in general sufficiently close to polar to get the desired global coverage while the constant geometry to the Sun is an advantage for the instruments.
The "frozen" orbit is selected as this is the closest to a circular orbit, possible in the gravitational field of the Earth. Terrain can be mapped from space with the use of satellites, such as Radarsat-1 and TerraSAR-X.

In 1990, Tyson Foods launched a line of Tyson Looney Tunes Meals. They were based on cartoon characters licensed from Warner Brothers and marketed aggressively toward children; the meals were taken off the market in late 1993, because of declining sales due to the Early 1990s recession. The packages featured Looney Tunes characters on the front, contained trading cards and stickers, they came in a divided tray with a main course, a side dish, a dessert. The dinners were to be heated in the microwave oven for two minutes, heated for another one or two minutes allowed to stand for an additional two to three minutes, for a total prep time of five to seven minutes. Similar products introduced by other companies about the same time for children aged 2 to 10 included Hormel "Kid's Kitchen," ConAgra Banquet brand "Kid Cuisine," and "My Own Meals."The meals were introduced with a fifteen million dollar advertising campaign, but there were concerns about the nutritional value of the meals and they were criticized for excess fat and salt.
During the economic recession, sales began to decline and, in 1993, the meals were taken off the market.

Haywood Highsmith is an American basketball player for the Delaware Blue Coats of the NBA G League. He played college basketball for Wheeling Jesuit University. Highsmith played four seasons for the Wheeling Jesuit Cardinals and became a starter for the team towards the end of his freshman season, he averaged 14.5 points and 9.4 rebounds as a sophomore, his full year as a starter, was named first team All-Mountain East Conference. In his junior season, Highsmith averaged 15.3 points and 10.8 rebounds and was named second team All-MEC. As a senior, High smith averaged 22 points and 12.6 rebounds per game and was named first team All-MEC, MEC Player of the Year, the MVP of the MEC Conference Tournament. Nationally, he was named first team Division II All-America by the National Association of Basketball Coaches and the National Player of the Year by the Division II Conference Commissioner’s Association. After going undrafted in the 2018 NBA draft, Highsmith signed with the Delaware Blue Coats of the NBA G League through a local try-out.
He averaged 13.7 points per game in 21 appearances. Highsmith was signed to a two-way contract by the Philadelphia 76ers on January 8, 2019. Under the terms of the deal, he will split time between the Blue Coats. Highsmith made his NBA debut the same day, scoring three points in five minutes of play in a 132-115 win over the Washington Wizards, after playing in a game for the Blue Coats against Raptors 905 earlier in the day. Highsmith finished his first professional season averaging 1.8 points and one rebound over five NBA games and 12.2 points, 6.8 rebounds, 2.5 assists, 1.2 steals over 46 G League games. On June 24, 2019, the 76ers waived Highsmith. After having his Exhibit 10 deal with the Phoenix Suns fall through, Highsmith returned to the 76ers to sign an Exhibit 10 contract, he re-joined the Blue Coats for the 2019–20 season.
