US space agency postpones launch of fastest object ever made on journey to Earth’s nearest star
US space agency postpones launch of fastest object ever made on journey to Earth’s nearest star
The United States voiced deep suspicion on Tuesday over Russia’s pursuit of new space weapons, including a mobile laser system to destroy satellites in space, and the launch of a new inspector satellite which was acting in an “abnormal” way.
What the heck is a Space Force? We finally (sort of) know.
The coronal mass ejection was as massive as scientists expected, but less energetic
The Earth has been through a lot of changes in its 4.5 billion year history, including a shift to start incorporating and retaining volatile compounds from the atmosphere in the mantle before spewing them out again through volcanic eruptions.
Before NASA’s newest planet-hunter TESS started science operations on July 25, the spacecraft sent back a series of images showing the motion of C/2018 N1, a comet recently discovered by the agency’s NEOWISE satellite.
A meteor hit the earth and exploded with 2.1 kilotons of force last month, but the US Air Force has made no mention of the event.
On Mars, the atmospheric pressure is around 0.6% of Earth’s. Any liquid water on the surface would very quickly evaporate or freeze. One of the challenges of terraforming the Red Planet is to increase its atmospheric pressure. The Martian polar caps, minerals, and soil could all provide sources of carbon dioxide and water to thicken the atmosphere. But a new study in the journal Nature Astronomy finds that processing all sources available on the planet would only increase the pressure to about 7% that of Earth, far short of what is needed.
The water body, if confirmed, could potentially harbor microbes
Future missions to Mars and beyond will require innovative options to shelter explorers. NASA’s 3D-Printed Habitat Challenge, a Centennial Challenges competition, seeks ways to create or develop the technologies needed to create such habitats on-site, and challenges citizen inventors to lead the way. Now a panel of experts from NASA, academia and industry has selected the top five teams to share a $100,000 prize in the Phase 3: Level 1 of the competition.
