That is what I learned from reading a wonderful article on the physics of bowling balls – written by Brendan Koerner and published on

TAMPA, Fla. — OneWeb’s broadband constellation is set to pass the 200th mark after Arianespace successfully launched its latest batch of satellites May 28. Arianespace launched 36 satellites on a Soyuz-2.1b rocket 1:38 p.m. Eastern from the Vostochny Cosmodrome, in Russia, which will enlarge OneWeb’s fleet to 218 satellites. The mission was initially scheduled for

The Space Force accounts for about 2.5% of the Defense Department’s $715 billion budget proposal. WASHINGTON — President Biden’s $715 billion defense budget proposal for 2022 includes $17.4 billion for the U.S. Space Force, about $2.2 billion more than what Congress enacted in 2021. The proposed $715 billion defense budget is $11.3 billion more than

This standing wave detonation was created in a prototype engine and the researchers say that such a system could

WASHINGTON — The Japanese and Canadian space agencies announced plans May 26 to send small rovers to the moon in the next several years, as Lockheed Martin unveiled a partnership with automaker General Motors to propose a rover for NASA’s Artemis program. The Japanese space agency JAXA said it is working with several Japanese companies

SEOUL, South Korea — South Korea signed the Artemis Accords May 27, becoming the 10th signatory to the pact that governs norms of behavior for those who want to participate in the NASA-led Artemis lunar exploration program. On the same day, South Korea and the United States signed an agreement on “civil global navigation satellite

WASHINGTON — A delay of up to two years in the next New Frontiers planetary science mission competition won’t change the potential destinations for that mission. NASA announced May 12 it was delaying the release of a draft announcement of opportunity for the fifth New Frontiers mission from this October to as late as October

On July 4, 2026, the United States will celebrate the 250th anniversary of its independence. America should commemorate this historical milestone in 2026 by landing humans on the moon for the first time since 1972. Sending humanity back to the moon in 2026 is not only technically feasible, but it also fits squarely in the

SAN FRANCISCO – At the direction of the Biden Administration, the National Oceanic and Atmospheric Administration’s National Environmental Satellite, Data and Information Service (NESDIS) is adopting a portfolio approach. “For us that means not just launching one satellite at a time and building that satellite really well, but seeing how all the systems work together,”

Kendall: If confirmed ‘I’ll evaluate the plans and directions currently being implemented’ WASHINGTON — President Biden’s nominee to be secretary of the Air Force Frank Kendall  told lawmakers May 25 he will ensure the Space Force gets the necessary resources to continue to stand up units and acquire new systems. During a Senate Armed Services

Rep. Jim Cooper worries that Space Force acquisitions are headed down a similar path as past Air Force programs WASHINGTON — The U.S. Space Force has plans to acquire billions of dollars worth of new satellites over the coming years and needs to make sure it avoids the missteps that plagued previous acquisitions, said the

TAMPA, Fla. — A OneWeb-led group has secured government funding to launch a beam-hopping satellite in 2022, demonstrating how a spacecraft could switch its coverage area in real-time to respond to surges in demand. OneWeb, which has launched a third of its initial 650-strong constellation to low Earth orbit (LEO), said the so-called Joey-Sat spacecraft
