Watch crews blow up huge boulder on Hwy. 120 near Yosemite to clear rocky road
The sound of springtime on Highway 120 near Yosemite National Park is boulders being blown to smithereens. 'Every spring in @caltransd9, our maintenance crews encounter large boulders on State Route 120 West near Yosemite that slid onto the road during winter,' Caltrans wrote in an Instagram post on Thursday. The video above shows road crews executing the detonations of RV-sized rocks from the roadway. 'This year we captured part of the extensive blasting process in what is just one of the many required steps to opening the roadway,' a caption with the video says. 'These state employees work tirelessly to ensure the roadway and entire canyon are clear of all unauthorized personnel and are a safe distance away before any detonation.' Tioga Road (Highway 120) reopened for the summer on May 26, according to and sierra mountain The route — which primarily connects the Sierra Nevada and Mono County to San Joaquin Valley and is known as a direct route to Yosemite National Park from the San Francisco Bay Area — was closed for the winter on Nov. 25.

Cops detonate old artillery shell found in Perak
Perak Tengah police chief Hafezul Helmi Hamzah said the bomb was found by a 55-year-old local man while carrying out routine work in the area at 8pm. (Facebook pic) PETALING JAYA : A 155mm artillery shell was found in an open area in Sungai Tumbuh, Bandar Universiti, Seri Iskandar, Perak, yesterday. Perak Tengah police chief Hafezul Helmi Hamzah said the old bomb, weighing 35kg, was found by a 55-year-old local man who was carrying out routine work there at about 8pm. 'The bomb disposal unit of the Perak police headquarters was dispatched to the location for further investigation,' Bernama reported him as saying. Hafezul said the unit then detonated the bomb at the site at 9am today. 'Further examination of the area where the bomb was discovered found the place to be safe,' he said.

Venus Aerospace debuts potentially revolutionary rocket engine with landmark 1st flight (video)

Houston-based startup Venus Aerospace has completed the first-ever test flight of a rotating detonation rocket engine (RDRE) in the United States. The launch took place on Wednesday (May 14) from Spaceport America in New Mexico. A small rocket equipped with Venus' RDRE lifted off at 9:37 a.m. EDT (1337 GMT; 7:37 a.m. local time in New Mexico). The milestone marked the first successful test of such an engine from U.S. soil and took Venus a "step closer to making high-speed flight accessible, affordable and sustainable," the company said in a statement. "This is the moment we've been working toward for five years," Venus CEO Sassie Duggleby said in the statement. The test serves as a proof of design for Venus's RDRE and keeps the company on track for runway-based high-speed flight, she added: "We've proven that this technology works — not just in simulations or the lab, but in the air." The Venus RDRE uses a compact, high-efficiency design the company hopes can eventually power aircraft up to Mach 6 — six times the speed of sound — starting from conventional runways. Compared to traditional rocket engines, RDREs offer greater thrust in smaller packages, but up until now the technology has been mostly theoretical. Normally, rocket engines burn fuel in a combustion chamber in a steady, controlled process. RDREs use a continuous detonation wave that travels in a circle within a ring-shaped chamber, which produces higher pressure and efficiency and results in increased thrust with less fuel.

"We've built an engine that not only runs, but runs reliably and efficiently — and that's what makes it scalable." The RDRE is designed to work in tandem with Venus's VDR2 air-breathing detonation ramjet — a combination the company says will enable sustained hypersonic flight without the need for a booster. (Hypersonic flight is generally defined as Mach 5 and above.) "This is the foundation we need that, combined with a ramjet, completes the system from takeoff to sustained hypersonic flight," Andrew Duggleby said. With the successful test in the books, Venus is planning full-scale propulsion test of their integrated system as it moves to qualify the design of its future Stargazer M4, a reusable passenger aircraft capable of reaching Mach 4.
