Heat transfer experiment arrives at International Space Station
Friday, 13 August 2021 09:52
People who design spacecraft must prioritize two factors: reducing weight and managing extreme temperatures.
A new experiment designed by Purdue University engineers addresses both problems. The Flow Boiling and Condensation Experiment (FBCE), which arrived at the International Space Station on Thursday (Aug.
Boeing Starliner launch faces further delays
Friday, 13 August 2021 07:52
Boeing's troubled Starliner spaceship could be set for further delays after the company said Thursday it was working to solve problems with the propulsion system.
The spaceship's latest launch date on August 4 was cancelled over propulsion issues, and it remains unclear when the next test flight will be scheduled.

Friday, 13 August 2021 07:52
A plan to use a Russian spacecraft to deorbit the International Space Station as early as 2028 remains in question because the United States does not know Russia's intentions for using the orbiting laboratory, NASA and other parties involved in the decision say.
A NASA safety panel approved a plan in 2019 that relies on Russia to modify and launch a Progress spacecraft to guide the stru Size of supermassive black hole divulged by eating pattern
Friday, 13 August 2021 07:52
Astronomers have finally linked the size of a supermassive black hole to the spectral patterns generated by its eating habits.
Most nearby supermassive black holes are dormant. These long-sated, sleeping giants ate up their supply of gas and dust many millions of years ago, leaving them dark and quiet.
To identify dormant black holes, scientists must measure their gravitational i Army successfully tests high-energy laser weapon
Friday, 13 August 2021 07:52
The U.S. Army says it's developed a combat-capable prototype of a high-energy laser weapon.
The laser, which has been 24 months in the making, can be mounted on a Stryker military vehicle and used to defend troops against drones as well as rockets, artillery and mortars, according to an Army press release this week.
Over the summer, the new weapon was successfully tested in Fort Exponential growth of cubesats may be tapering off

During close pass, Solar Orbiter captures Venus' glare
Thursday, 12 August 2021 19:12
On Aug. 9, 2021, ESA/NASA's Solar Orbiter spacecraft passed within 4,967 miles (7,995 kilometers) of the surface of planet Venus. In the days leading up to the approach, the Solar Orbiter Heliospheric Imager, or SoloHI, telescope captured this gleaming view of the planet.
The images show Venus approaching from the left while the Sun is off camera to the upper right. The planet's nightside, the part hidden from the Sun, appears as a dark semicircle surrounded by a bright crescent of light – glare from Venus' incredibly bright sunlit side.
"Ideally, we would have been able to resolve some features on the nightside of the planet, but there was just too much signal from the dayside." said Phillip Hess, astrophysicist at the Naval Research Laboratory in Washington, D.C. "Only a sliver of the dayside appears in the images, but it reflects enough sunlight to cause the bright crescent and the diffracted rays that seem to come from the surface."
Two bright stars are also visible in the background early in the sequence, before being eclipsed by the planet.

New project will simulate life on Mars, pave way for NASA's 'next giant leap'
Thursday, 12 August 2021 14:23
As NASA prepares for its "next giant leap"—meaning astronauts on Mars—technology developed by Austin-based 3D printing construction company Icon is helping pave the way.
Icon has landed a subcontract with the National Aeronautics and Space Administration, and is teaming with Bjarke Ingels Group, to construct and design a habitation unit that will help the space agency better understand how people may be able to live on Mars in the future.
The company is building a 3D printed structure at NASA's Johnson Space Center in Houston for a series of missions designed to simulate what life could look like for astronauts living on Mars. Once completed, crews will stay in the structure at the Houston space center for one-year stints designed to mimic living conditions on the red planet.
Icon, which printed its first home using 3D technology in 2018, was co-founded by Jason Ballard with the goal of reimagining construction and housebuilding by using novel building techniques to make homes more affordable, resilient and sustainable. The startup has built a number of projects on Earth and has been working to take its technology to new heights by aiming to construct some of the first habitable structures in space.
