What is your idea of an asteroid? Many people think of them as potato-shaped, inert and perhaps rather dull, pock-marked objects—far away in deep space. But over the last ten years, two Japanese space missions – Hayabusa and now Hayabusa 2 – have dispatched that view to the history books. Asteroids are interesting bodies that may be able to explain how life on Earth came about.
The Japanese Space Agency, JAXA, is about to bring back samples to Earth from the 1km-wide asteroid Ryugu – with touchdown expected on December 6 at a military test site in South Australia. The first Hayabusa craft returned samples from asteroid Itokawa in 2010, which like Ryugu orbit the Sun near Earth. I'm one of the scientists who analyzed the grains, and am now looking forward to investigating Ryugu.
HELSINKI — China’s Chang’e-5 spacecraft are preparing for a first-ever robotic rendezvous and docking in lunar orbit, a major hurdle to delivering lunar samples to Earth.
WASHINGTON — When Virgin Galactic’s SpaceShipTwo takes to the skies above New Mexico later this month, it will do so without the crowds and publicity once expected for the historic flight.
Virgin Galactic announced Dec.
Outer space activities are more important to the United States now than at almost any time in our history. Space technology and services provide critical national security capabilities, scientific knowledge, economic opportunities, and the tools to understand and respond to a changing climate.
If intelligent aliens visit the Earth, it would be one of the most profound events in human history.
Surveys show that nearly half of Americans believe that aliens have visited the Earth, either in the ancient past or recently. That percentage has been increasing. Belief in alien visitation is greater than belief that Bigfoot is a real creature, but less than belief that places can be haunted by spirits.
Scientists dismiss these beliefs as not representing real physical phenomena. They don't deny the existence of intelligent aliens. But they set a high bar for proof that we've been visited by creatures from another star system. As Carl Sagan said, "Extraordinary claims require extraordinary evidence."
Unidentified flying objects
UFO means unidentified flying object. Nothing more, nothing less.
There's a long history of UFO sightings. Air Force studies of UFOs have been going on since the 1940s.
In a new paper published in the journal Nature Communications Earth and Environment, researchers at the University of Rochester were able to use magnetism to determine, for the first time, when carbonaceous chondrite asteroids—asteroids that are rich in water and amino acids—first arrived in the inner solar system.
It goes without saying that the federal government has a reputation for presenting startups with some formidable barriers to entry when it comes to securing government contracts.
We know those barriers exist for a reason – they increase compliance, reduce risk and ensure taxpayer dollars are spent responsibly.
WASHINGTON — Blue Origin has achieved a new milestone in the development of the engine that will power the lunar lander it seeks to provide for NASA’s Artemis program.
The company announced Dec. 4 that it started a fourth series of hotfire tests of the thrust chamber for the BE-7 engine.
A new space tourism company plans its first uncrewed test flight of a capsule suspended from a hydrogen balloon in late March from Florida. Arizona-based Space Perspective has announced plans to launch the balloon from Kennedy Space Center's former space shuttle landing strip, sending it on an hour's long ascent to the edge of space, about 20 miles high. The company's ambitions a
Lockheed Martin has announced the U.S. Space Force has determined the fifth Space Based Infrared System Geosynchronous Earth Orbit satellite (SBIRS GEO-5) is complete and ready for launch in 2021. Built in a record time and at no additional cost to the government for the upgrade, SBIRS GEO-5 is the first military space satellite built on the company's modernized, modular LM 2100 combat bus
The Earth observation satellite FalconEye was successfully launched last night from the European Spaceport (CSG) in Kourou, French Guiana by an Arianespace Soyuz rocket. Owned and operated by the United Arab Emirates, FalconEye was developed by Airbus Defence and Space and Thales Alenia Space as co-prime contractors. The FalconEye system will support the needs of the UAE's Armed Forc
Northrop Grumman Corporation has successfully completed multiple rounds of tests on its Solid Fuel Ramjet (SFRJ) tactical engine configuration - a technology to enable long range precision fires, one of the U.S. Army's key priorities. Conducted as part of phase one of the U.S. Army's XM1155 Extended-Range Artillery Projectile (ERAP) program, the SFRJ tests validated gun-launched survivabil
Long ago, all the continents were crammed together into one large land mass called Pangea. Pangea broke apart about 200 million years ago, its pieces drifting away on the tectonic plates - but not permanently. The continents will reunite again in the deep future. And a new study, presented during an online poster session at the meeting of the American Geophysical Union, suggests that the future
