As Deputy Director of NASA Pam Melroy was getting ready for the space shuttle When she was launched as an astronaut in the early 2000s, she told relatives to plan a week-long vacation trip to Florida.
member of The Artemis I mission team gave the same advice to their families. That’s because many factors need to work properly for a successful space launch.
The launch team decided to postpone Artemis I’s takeoff on Monday due to weather delays and mechanical issues during the countdown.
A second launch, scheduled for Saturday afternoon, was also canceled.
A nasty liquid hydrogen leak is responsible for Artemis I’s second scrub.
Liquid hydrogen is one of the propellants used in the large core stages of rockets. The leak prevented the launch team from filling the liquid hydrogen tank despite repeated attempts to troubleshoot.
NASA plans to share an update on Saturday at 4pm.
NASA administrator Bill Nelson said mission managers will meet to discuss next steps and decide if a launch is possible on Monday or Tuesday, or if the rocket stack should be returned to the vehicle assembly building. If it winds up on the building, it may not be able to launch until mid-October.
Archaeologists have used ancient DNA to unlock medieval mysteries.
The bodies of six adults and 11 children found by builders at the bottom of an 800-year-old well in Norwich, England, have been identified as victims of anti-Semitic violence.
The researchers said the findings shed light on the “genuine horror” experienced by the persecuted Jewish community.
Encounters with our planet’s deep past can happen anywhere.
A property owner in Portugal came across fossilized dinosaur fragments when a towering sauropod sternum was found during construction work.
Paleontologists believe the dinosaur was about 39 feet (12 meters) tall and 82 feet (25 meters) long.
Unlike Earth, Mars has no oxygen-producing forests. But NASA and Massachusetts Institute of Technology engineers have tested a machine tree that has the potential to make Mars more welcoming to astronauts.
The toaster-sized tech demo has produced oxygen in seven experiments in varying atmospheric conditions since April 2021.
MOXIE hit its target of producing 6 grams of oxygen per hour every time it was run. This is comparable to the speed of moderate trees on Earth. Researchers hope that a scaled-up version will produce enough oxygen to sustain humans on Mars and fuel rockets for astronauts to return to Earth.
The Great Pyramids of Giza were the tallest buildings in the world for about 4,000 years.
How this monumental feat of ancient engineering was put together is still a mystery, but new research suggests that pyramid builders used a lost tributary of the Nile River to move building materials. It supports a long-standing theory.
However, by the time Alexander the Great conquered Egypt in 332 BC, environmental factors had reduced Khufu’s tributaries to tiny channels, research has found.
