This NASA visualization shows a rapid decline in Arctic Sea ice over the last 35 years, based on satellite observations. The situation is really bad: in the 1st week of January 1988, over 1.2 million sq. miles (3.1 million km2) were covered by sea ice 4 years of age or older, compared with just over […]
Earth’s atmosphere is leaking: around 90 tonnes of material escapes and streams out into space from our planet’s upper atmosphere every single day. To understand this escape, NASA launches rockets into space. The space agency also sends scientists to a tiny Arctic town named Ny-Ålesund (English: New Alesund) on the island of Spitsbergen in Svalbard, […]
An amazing video by NASA titled “Curiosity at Martian Scenic Overlook”. Curiosity Project Scientist Ashwin Vasavada gives a descriptive tour of the Mars rover’s view in Gale Crater which is 154 kilometers (96 miles) in diameter and estimated to be about 3.5-3.8 billion years old. It is created by an impactor. The crater is also […]
A short but amazing video showing both an aurora and sunrise from the International Space Station (ISS), published by the NASA Johnson channel.
From an all-female spacewalk to the first image of a black hole, a lot has changed in the last twenty years of space exploration.
NASA has published a beautiful photo of Apollo 12 at the launch pad 39A at the Kennedy Space Center Launch Complex 39. This historic image, taken on October 28, 1969 (50 years ago) frames the Apollo 12 spacecraft atop the mighty Saturn V rocket and its destination, the Moon, in a single photo.
On October 24, 2019, NASA has published a new selfie of the Curiosity Mars Rover, which was taken on October 11, the 2,553rd Martian day, or sol, of the rover’s mission. The space agency has also announced that Curiosity’s successor, the Mars 2020 Rover now stands on its own six wheels.
On October 18, 2019, NASA held an AMA (Ask Me Anything) on Reddit. Scientists from the space agency answered questions about Van Allen Probes, two robotic spacecraft that were used to study the Van Allen radiation belts that surround planet Earth.
A good rule of thumb: if you see a headline saying something “breaks the laws of physics” (i.e. the “Impossible Engine”) the headline is flat-out wrong.
NASA astronauts and ISS Expedition 61 Flight Engineers Christina Koch and Jessica Meir have completed the first-ever all-female spacewalk in the history of space exploration. The spacewalk was broadcast live on NASA TV (see the video below).
