T he last time I talked to Butch Wilmore and Suni Williams—the two astronauts now stranded aboard the International Space Station (ISS)—was on May 1, 2024. At the time, they were in pre-flight ...
Recently released photos of two NASA astronauts stranded aboard the International Space Station (ISS) have caused health concerns to rise. Although Sunita Williams and Barry Wilmore were ...
The European Space Agency last week released four stunning high-res images that show the sun in all its fiery glory. Newly-released photos capture the sun in highest resolution ever, space agency says
For a spacecraft the main environmental interactions are the energy coming from the Sun and the heat radiated to deep space. Other parameters also influence the thermal control system design such as the spacecraft's altitude, orbit, attitude stabilization, and spacecraft shape. Different types of orbit, such as low Earth orbit and geostationary ...
In interplanetary space, however, it is believed that thin aluminium shielding would give a net increase in radiation exposure; thicker shielding would be needed to block the secondary radiation. [35] [36] Studies of space radiation shielding should include tissue- or water-equivalent shielding along with the shielding material under study.
The James Webb Space Telescope is a space telescope operated by NASA and designed primarily to conduct infrared astronomy. Launched in December 2021, the spacecraft has been in a halo orbit around the second Sun–Earth Lagrange point (L 2 ), about 1.5 million kilometers (900,000 mi) from Earth, since January 2022.
Scientists on Tuesday unveiled the first pictures taken by the European space telescope Euclid, a shimmering and stunning collection of galaxies too numerous to count. The photos were revealed by ...
The magnitude of the energy of cosmic ray flux in interstellar space is very comparable to that of other deep space energies: cosmic ray energy density averages about one electron-volt per cubic centimetre of interstellar space, or ≈1 eV/cm 3, which is comparable to the energy density of visible starlight at 0.3 eV/cm 3, the galactic magnetic ...
