Physicists looking for signs of primordial gravitational waves by sifting through the earliest light in the cosmos - the cosmic microwave background (CMB) - have reported their findings: still nothing. But far from being a dud, the latest results from the BICEP3 experiment at the South Pole have tightened the bounds on models of cosmic inflation, a process that in theory explains several p

NASA Administrator Bill Nelson is announcing new leadership roles, as well as the merging of two offices into the Office of Technology, Policy, and Strategy (OTPS), in support of Biden-Harris Administration priorities and the focus on space strategy. OTPS is being established to provide data- and evidence-driven technology, policy, and strategy advice to NASA leadership. The office is a me

The first four Artemis missions will use NASA's 16 upgraded RS-25 engines that previously powered space shuttle flights. For future flights on the Space Launch System (SLS), NASA and prime contractor Aerojet Rocketdyne are changing the way they build major parts for the RS-25. Engineers and technicians are fabricating some of these parts using advanced manufacturing techniques that increase reli

NASA is continuing to investigate why the instruments in the Hubble Space Telescope recently went into safe mode configuration, suspending science operations. The instruments are healthy and will remain in safe mode while the mission team continues its investigation. Hubble's science instruments issued error codes at 1:46 a.m. EDT Oct. 23, indicating the loss of a specific synchronization

The first set of satellites Amazon plans to send to space along with Verizon will be launched next fall, according to an experimental launch license filed Monday. The company plans to send up to 3,236 satellites as part of Project Kuiper, a satellite-internet service that will serve rural communities that lack terrestrial infrastructure. Two satellites - called KuiperSat-1 and K

NASA has selected the CubeSat Imaging X-Ray Solar Spectrometer (CubIXSS), led by Southwest Research Institute, to measure the elemental composition of hot, multimillion-degree plasmas in the Sun's corona - its outermost atmosphere. The nanosatellite is expected to be launched in 2024 as a secondary payload on another satellite launch. CubIXSS will determine the origins of hot plasma - highly ion

Planets and their stars form from the same reservoir of nebular material and their chemical compositions should therefore be correlated but the observed compositions of planets do not match completely those of their central stars. In our Solar system, for example, all the rocky planets and planetesimals contain near-solar proportions of refractory elements (elements like aluminum that cond

NASA and SpaceX on Monday delayed for the second time a mission to send four astronauts to the International Space Station due to a "minor medical issue" with a crew member. "The issue is not a medical emergency and not related to COVID-19," NASA said in a statement, without giving further details. The members of "Crew-3" - US astronauts Raja Chari, Kayla Barron and Tom Marshburn, as we
