Science and technology, explained simply
Astronauts have problems with their finger nails during spacewalks. Space is not the most comfortable environment for humans. If there are no normal earthly conditions, including the usual gravity, then a person begins to experience health problems. First of all, it concerns the loss of bone and muscle density. Studies show that another disadvantage of […]
NASA has announced that two scientific spacecraft will travel to Mars in August 2024 aboard a Blue Origin rocket owned by Jeff Bezos. This decision apparently came about after Elon Musk’s SpaceX encountered difficulties in its attempts to deliver Falcon Heavy rockets to Mars orbit. Initially, SpaceX planned to deliver NASA’s spacecraft to Mars in […]
Researchers from the American Space Agency have achieved impressive success in optical communication, transmitting messages from the Psyche spacecraft to Earth from a distance of 16 million kilometers. The Deep Space Optical Communications (DSOC) system used a near-infrared laser encoded with test data to transmit a message from Psyche to a distance 40 times the […]
NASA and the Japan Aerospace Exploration Agency (JAXA) are planning to launch the world’s first wooden satellite into space to make spaceflight more sustainable. According to space agencies, LignoSat, a coffee-cup-sized satellite made of magnolia wood, is scheduled to be launched into Earth orbit by the summer of 2024. Wood doesn’t burn or rot in […]
NASA has tested the most powerful electric rocket engine in history. It is intended for the Lunar Gateway orbital station. Until recently, the most powerful electric rocket engine was a 4.5 kW propulsion system. Aerojet Rocketdyne’s solution was chosen for Lunar Gateway. The new electric rocket engine has a power of 12 kW. It was […]
The world’s inhabitants can see the new temporary “satellite” of the Earth with their own eyes. This is a bag of tools that was lost by NASA astronauts. In November, NASA astronauts Jasmin Moghbeli and Loral O’Hara launched a bag of instruments into space. The incident occurred during scheduled repairs on the outside of the […]
An unexpected object has been added to the list of man-made satellites. On November 2, 2023, during a spacewalk from the International Space Station (ISS), NASA astronauts Jasmine Mogbeli and Loral O’Hara dropped a bag of instruments that now orbits our planet with a visual magnitude of about 6. This means that it is slightly […]
NASA scientists have presented an amazing image of the protostellar jet HH212, located in the constellation Orion. This photo, taken with the James Webb Space Telescope, shows the Sun’s unusually violent birth and growth. The image shows powerful gas emissions and jets of energy, which is a characteristic phenomenon during the birth of stars. The […]
The SWOT spacecraft has completed the first complete study of the planet’s water surface. NASA scientists used SWOT data to create a map of water on Earth, which shows the different surface levels of the planet’s oceans, freshwater lakes and rivers. These data were collected during the spacecraft’s first full 21-day scientific mission from July […]
NASA has announced a new streaming service called NASA+, which will be available on most major platforms next week. It will be a completely free service, with no subscription fees, and you won’t have to watch ads. NASA+ will be available from November 8. The space agency announced the release of its upcoming streaming service […]
