SpaceX said the craft was undergoing a "series of engine tests" at a facility in Cape Canaveral, and something went wrong during the final stretch. SpaceX will work with NASA to determine what caused the issue. "Ensuring that our systems meet rigorous safety standards and detecting [issues] like this prior to flight are the main reasons why we test," SpaceX …

Oceans are hotter than they've ever been in recorded history. Ice Sheets are melting at unprecedented rates. Sea-level rise threatens countless species, coastal cities, and local economies. As researchers' warnings about the consequences of climate change are getting worse, some scientists and politicians are suggesting we do more than just curb our greenhouse gas emissions – they want to hack …

There is no meteor shower to light up the sky since early January, and this one will be visible around the globe. The moon was full Friday, so it will still be pretty bright in the early morning hours over the weekend and during the peak. Late evening hours based on your location, between 9 pm and midnight local time, …

This new technique uses CRISPR-Cas3, while most of the work we've seen so far has been made with CRISPR-Cas9. The tool uses a complex of riboprotein, known as Cascade, to seek its purpose, and an enzyme called Cas3 to tear the DNA. As a result, it can move along the DNA of dozens of kilobases long and break the genetic …

And it's not just the shorter spans of sunlight during the winter months that are a problem; even a light dusting of snow can render solar panels ineffective. As a result of global warming, the winters are only going to get more severe, but there …

Just minutes before SpaceX began fueling Falcon Heavy for its commercial launch debut, NASA announced that the company had won a contract for its Double Asteroid Redirection Test (DART) mission to be launched by Falcon 9 for the low cost of $ 69M . Designed to cost less than $ 250M total, the DART mission will aim to be as …

Falcon Heavy Ranks as the most powerful rocket in the world, with 27 engines creating 5.1 million pounds of thrust – the equivalent of about 18 Boeing 747 aircraft combined. For all the racket's gusto, however, the question of whether Falcon Heavy would succeed in both winning contracts and launching valuable payloads remained. Falcon Heavy was unveiled in 2011 and, …

The majority of changes that occurred in Kelly's body, compared to his identical brother, Mark, on Earth, returned to normal once he came back from the space station. The study suggests that human health can be "mostly sustained" for a year in space, researchers said. Coincidentally, the results are being released just in time for the 58th anniversary of the …

Early Wednesday morning, and a huge collaboration of scientists are expected to release the first images of the event horizon of a black hole, built from data gathered by observatories all over the globe. Combined, the telescopes created a virtual telescope as big as Earth itself that is powerful enough to capture enough data from the supermassive black hole in …

Enlarge / SpaceX's Crew Dragon approaches the International Space Station in March, 2019. NASA ago, NASA faced a difficult decision. The agency had spent about $ 1.5 billion to help Boeing, SpaceX, and Sierra Nevada Corporation design a spacecraft that could carry US astronauts to the International Space Station. NASA had a total of $ 7 billion to be distributed …
