NASA Space Technology NASA Hubble Mission TeamGoddard Space Flight CenterSep 18, 2024This NASA/ESA Hubble Space Telescope image features the spiral galaxy IC 4709 located around 240 million light-years away in the southern constellation Telescopium. Hubble beautifully captures its faint halo and swirling disk filled with stars and dust bands. The compact region at its core might be the most remarkable sight. It holds an active galactic nucleus (AGN).If IC 4709’s core just held stars, it wouldn’t be nearly as bright. Instead, it hosts a gargantuan black hole, 65 million times more massive than our Sun. A disk of gas spirals around and eventually into this black hole, crashing together and heating up as it spins. It reaches such high temperatures that it emits vast quantities of electromagnetic radiation, from infrared to visible to ultraviolet light...

NASA Space Technology The radiation dose for the 2.5 year round trip between Earth and Mars should give approximately a 1% lifetime increase of a fatal cancer. SpaceX Starship will totally change the situation on payload and travel times. The Starship will be refueled in Earth Orbit. All NASA missions to Mars have launched with multiple stages get to orbit and then to go to Mars. This means the final stage that goes to Mars has to go smaller and slower. They are about 20 times smaller than the launch rocket and they go about 2-3 times slower than a fully fueled in orbit Starship.Starship could travel to Mars one-way in 70-90 days without extra exceptional effort beyond refueling in orbit. This is better than the 180-270 days of other vehicles. Reduced travel time would...

NASA Space Technology Boeing has been silent ever since the National Aeronautics and Space Administration (NASA) decided to bring Starliner back to Earth without its crew members.The absence of Boeing officials during the news conference held after Starliner's landing on Earth on September 7 fueled speculation about a rift between NASA and Boeing.The US space agency and the aerospace company joined hands to carry out Starliner's first crewed flight to space. NASA astronauts Sunita Williams and Butch Wilmore became the first persons to fly on Boeing's Starliner spacecraft.Sunita Williams and Butch Wilmore had launched aboard Starliner's Calypso spacecraft on June 5. They reached the International Space Station on June 6.The duo was supposed to return to Earth on Starliner within days. However, their return was delayed after Starliner was detected with technical issues involving helium...
