DENVER, July 11, 2018 /PRNewswire/ — Lockheed Martin (NYSE: LMT) has embraced a 3D printed titanium dome for satellite fuel tanks so big you can’t even put your arms around it. The 46-inch- (1.16-meter-) diameter vessel completed final rounds of quality testing this month, ending a multi-year development program to create giant, high-pressure tanks that carry fuel on board satellites.
The titanium tank consists of three parts welded together: two 3D printed domes that serve as caps, plus a variable-length, traditionally-manufactured titanium cylinder that forms the body.

July 12 (UPI) — By combining the observations of the two most powerful space telescopes in orbit, scientists have achieved the most precise measurement of the Hubble constant, the universe’s expansion rate.
The new measurement confirms the tension between explosion rate in the early and late universe, researchers report.
Astronomers can measure the expansion of the universe by measuring a galaxy’s redshift, a change in the wavelength of the light due to a change in the velocity of the object. By measuring the redshift of galaxies using the Hubble Telescope, scientists have established the Hubble constant.
