Sentinel is a space-based infrared (IR) survey mission to discover and catalog 90 percent of the asteroids larger than 140 meters in Earth’s region of the solar system. The mission should also discover a significant number of smaller asteroids down to a diameter of 30 meters. Sentinel will be launched into a Venus-like orbit around the sun, which significantly improves the efficiency of asteroid discovery during its 5.5 year mission.

The non-profit B612 Foundation aims to build, launch, and operate the first privately funded deep space mission—a space telescope in orbit around the Sun that will map the inner Solar System in search of asteroids that could impact Earth.

Asteroids are a scientific and economic opportunity in that they contain the original building blocks of the Solar System. They are targets for future human exploration, and may contain valuable raw materials for mining. These asteroids are also a threat in that they can pose great risk to humanity here on Earth. Taking advantage of these opportunities and dealing with these threats require not only knowing where each of these individual asteroids is now, but also projecting where they will be in the future.

Have you ever wondered why some telescopes are launched into space while others are built on remote mountain tops? What is actually the best for astronomy? Here we provide a ringside view of the fight for the elusive photons from deep space - is it a battle of the telescope giants?

Benefits of space surround us. Exploration fuels innovation. Groundbreaking technologies we develop to explore space keep us close and safe right here at home.

An idea born in unsettled times becomes a feat of engineering excellence. The most complex machine ever built to bring humans to and from space and eventuall...

NASA's Space shuttle last mission lift off. Shuttle Endeavour went to space for the last time on May 16th, 2011 at 8:56 AM EDT. By Wednesday May 18th they will have reached the space station and their return back after a 16 day mission is expected by early June, 2011

Swiss Space Center at EPFL just launched the "CleanSpace One" project. The aim is to design and build a satellite that will chase, grab and destroy a space debris - namely one of the first Swiss satellites, Swisscube-1 or TIsat-1.

The first American woman in Space talks about her historic flight on NASA's 50th anniversary. She flew aboard Space Shuttle Challenger in June 1983 on the STS-7 mission.

NASA's Mars Exploration Rover Mission (MER) is an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the sending of the two rovers—MER-A Spirit and MER-B Opportunity—to explore the Martian surface and geology.
