Protecting Earth From Asteroids Using Stardust
2013-11-18 17:41:17

Lee Rannals for redOrbit.com – Your Universe Online A new research program is bringing experts together to help protect our planet from asteroids that could become catastrophes. The Stardust program is the first research-based training network of its kind, bringing together some of the world’s best experts on asteroids and space debris. An open training school is being held at the University of Strathclyde this week in the first step to train the next generation of scientists,...

No Damages Reported As GOCE Satellite Falls Back To Earth
2013-11-11 07:39:22

[ Watch the Video: GOCE Safely Burns Up In The Atmosphere ] redOrbit Staff & Wire Reports - Your Universe Online A defunct satellite that had been mapping the Earth’s gravitational field fell back to Earth at approximately 7pm ET Sunday (01:00 CET Monday), the European Space Agency (ESA) has confirmed. The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) probe re-entered the planet’s atmosphere during a descending orbital pass extending across Siberia, the...

GOCE Mission Comes To An End
2013-10-22 13:11:50

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced on Monday its Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission has come to an end. ESA said that after mapping the Earth's gravity for four years the satellite has finally run out of fuel, effectively ending the mission. GOCE's gradiometer instrument was the first of its kind in space and it helped to map variations in Earth's gravity with unrivaled precision. GOCE...

Threat Of Space Debris On Human Spacecraft
2013-09-28 08:25:22

NASA More than 500,000 pieces of debris, or “space junk,” are tracked as they orbit the Earth. They all travel at speeds up to 17,500 mph, fast enough for a relatively small piece of orbital debris to damage a satellite or a spacecraft. The rising population of space debris increases the potential danger to all space vehicles, but especially to the International Space Station, space shuttles and other spacecraft with humans aboard. NASA takes the threat of collisions with space...

Gravity Satellite Mission To End This Fall
2013-09-14 03:50:00

April Flowers for redOrbit.com - Your Universe Online After four years of working to map out Earth's gravity, the European Space Agency's (ESA) Gravity field and steady-state Ocean Circulation Explorer (GOCE) mission is nearing its end. The satellite, which has been orbiting Earth since 2009 at the lowest altitude of any research satellite, will reenter our atmosphere soon. GOCE has been called the "Ferrari of space" because of its sleek, aerodynamic design. This designer spacecraft has...

Protecting Spacecraft From Space Junk
2013-06-27 16:16:45

Lee Rannals for redOrbit.com - Your Universe Online Researchers developed a numerical algorithm that simulates the shock of orbital debris striking materials that make up a space vehicle's outer defense. Scientists commonly use supercomputers to investigate physical phenomenon that cannot be duplicated in a laboratory environment. By running simulations on these such computers, University of Texas researchers have assisted NASA in the development of ballistic limit curves that predict...

Astronomers Catch Bright Explosion On The Moon
2013-05-17 13:55:31

[ Watch the Video: Bright Explosion on the Moon ] Lawrence LeBlond for redOrbit.com - Your Universe Online If you take a good look at the Moon it isn´t too difficult to paint a pretty clear picture of the lunar surface´s violent past. Our neighboring natural satellite is pock-marked with thousands upon thousands of craters from meteors and asteroids that have been pelting its surface for more than a billion years. Over the past eight years, NASA astronomers have been...

European Conference Attendees Agree Action Needed On Space Debris
2013-04-25 15:36:38

Lee Rannals for redOrbit.com — Your Universe Online The findings from the 6th European Conference on Space Debris were released during a press briefing at the ESA's European Space Operations Center (ESOC) in Darmstadt, Germany. The conference included over 350 worldwide participants representing all the major national space agencies, industry, governments, academia and research institutes. “There is a wide and strong expert consensus on the pressing need to act now to...

Experts To Meet In Europe To Discuss Space Debris Issue
2013-04-18 14:14:48

Lee Rannals for redOrbit.com — Your Universe Online Hundreds of experts from all over the world will be meeting at Europe's largest-ever space debris forum next week to discuss the latest findings on the growing problem of space junk. Space debris not only poses problems to other satellites and spacecraft in orbit but it is also hazardous to astronauts aboard the International Space Station (ISS). Scientists believe there could be around 29,000 objects larger than 4 inches,...

How To Remove Orbital Debris With Less Risk
2013-03-22 20:53:40

Lee Rannals for redOrbit.com — Your Universe Online An article coming out in the Journal of Spacecraft and Rockets pitches ideas to attempt to remove orbital debris with less risk. The article, authored by Kerry Nock and Dr. Kim Aaron, of Global Aerospace Corporation (GAC), and Dr. Darren McKnight, of Integrity Applications Incorporated, Chantilly, VA, compared in-orbit debris removal options regarding their potential risk of creating new orbital debris or disabling working...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
