Air Force's 'Neighborhood Watch' Program Will Spy On Other Countries
2014-02-24 13:38:00

Lee Rannals for redOrbit.com - Your Universe Online General William Shelton said at the Air Force Association meeting in Orlando on Friday that the US will be launching satellites to spy on other countries. The head of Air Force Space Command said at the event that the “neighborhood watch program” will provide spying capabilities, as well as added eyes in the sky to keep track of space debris while orbiting 22,300 miles above the Earth. Shelton said the satellites will be used to...

Sentinel-1 Unfolds Its Wings
2014-02-21 12:12:50

ESA [ Watch The Video: Solar Wing Test ] When Sentinel-1 is placed in orbit around Earth in a few weeks, it has to perform a complicated dance routine to unfold its large solar wings and radar antenna. Engineers have recently been making sure the moves are well rehearsed. Sentinel-1 is the first in a family of satellites built specifically to provide a stream of timely data for Europe’s ambitious Copernicus environmental monitoring programme. It carries an advanced radar...

How Do You Catch A Satellite?
2014-02-21 10:50:46

ESA Standard space dockings are difficult enough, but a future ESA mission plans to capture derelict satellites adrift in orbit. Part of an effort to control space debris, the shopping list of new technologies this ambitious mission requires is set for discussion with industry experts. ESA’s Clean Space initiative is studying the e.DeOrbit mission for removing debris, aiming to reduce the environmental impact of the space industry on Earth and space alike. Earth's debris halo...

Neosat Boosting Europe’s Telecommunications By Satellite
2014-02-21 10:39:01

ESA ESA is forging ahead with the Neosat next-generation satcom platform, planning the first flights within five years. The goal is for European satellite builders to capture at least half of the world’s satcom market in 2018–30 through innovation and efficiency, generating €25 billion in sales. The contract for Phase-B of Neosat was signed today by Magali Vaissiere, ESA’s Director of Telecommunications and Integrated Applications, and Eric Béranger and Bertrand Maureau for...

Space Debris Threat From Envisat Explored By University Of Leicester Students
2014-02-20 07:32:18

redOrbit Staff & Wire Reports - Your Universe Online A recently-published paper from physics students at the University of Leicester explores the possibility that a massive observational satellite that lost contact with Earth in 2012 could be the catalyst that sets off a chain of events much like those depicted in the Academy Award-nominated film Gravity. Writing in the Journal of Physics Special Topics, a peer-reviewed student journal run by the University’s Department of Physics...

Proba-V Working Around The Clock
2014-02-18 08:49:27

ESA More than 5000 images, 65 daily global maps and six 10-day global syntheses, plus a quick peek at the Olympics: in its first two months of work, the vegetation-monitoring Proba-V minisatellite has yielded a valuable harvest for around a hundred scientific teams around the globe. Measuring less than a cubic metre, Proba-V tracks vegetation growth across the world on a near-daily basis – 93% of the globe is covered in one day, 100% in two days – using its main wide-viewing...

New Project Aims To Offer Free Global WiFi Service From Outer Space
2014-02-17 13:22:20

[ Watch the Video: Outernet Would Provide Wi-Fi From Space ] Lee Rannals for redOrbit.com - Your Universe Online A project being incubated by the Media Development Investment Fund (MDIF) has ambitious plans to beam WiFi to everyone on the planet for free. The organizations says that it is planning a project called “Outernet,” which will utilize a satellite constellation to make Internet universally-accessible and for no cost. Outernet says on its site that there are more...

Soviet-era Spy Satellite Burns Up Harmlessly In Earth's Atmosphere
2014-02-17 05:57:42

Lawrence LeBlond for redOrbit.com - Your Universe Online Fragments of a Soviet-era spy satellite, which was expected to crash back to Earth, had instead burned up on reentry into the atmosphere on Sunday. Colonel Dmitry Zenin, a spokesman for the Russian Defense Ministry, told Itar-Tass news agency that Kosmos-1220, a military signal intelligence satellite, reentered Earth’s atmosphere and burned up at about 5:58 p.m. local time (8:58 a.m. EST). The satellite, which had been in...

NASA Currently Testing New Technologies For Robotic Refueling
2014-02-13 10:28:50

Dewayne Washington/Adrienne Alessandro - NASA [ Watch The Video: Another Step Toward Servicing Satellites in Space ] It's corrosive, it's hazardous, and it can cause an explosion powerful enough to thrust a satellite forward in space. Multiple NASA centers are currently conducting a remotely controlled test of new technologies that would empower future space robots to transfer this dangerous fluid -- satellite oxidizer -- into the propellant tanks of spacecraft in space today....

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

Orbit -- An orbit is the path that an object makes around another object under the influence of some force. The classical example is that of the solar system, where the Earth, other planets, asteroids, comets, and smaller pieces of rubble are in orbit around the Sun; and moons are in orbit around planets. These days, many artificial satellites are in orbit around the Earth. Understanding orbits There are a few common ways of understanding orbits. -- As the object moves, it...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
