Stingray-inspired spacecraft could eventually probe the atmosphere of Venus




 

NASA's next Venus probe could be an atmosphere-skimming robotic stingray designed by the University of Buffalo. UB's CRASH Lab, which is the institution's Crashworthinesss for Aerospace Structures and Hybrids laboratory, has been selected by NASA to get early-stage funding as part of a program the agency devised to come up with new and innovative concept designs.

The stringray-style spacecraft design would have "wings" that can flap in the high winds of the upper atmosphere of Venus, according to UB, which would allow controlled flight that's possible with high efficiency. Using this design, the BREEZE design (as it's called) would be able to make its way all the way around Venus every four to six days, powering itself back up every two to three days while spending time on the sun-illuminated side of the planet.

Each "day" on Venus is longer than a year on Earth, because of the way it orbits the Sun. That means that typical spacecraft design wouldn't necessarily be able to stay aloft and powered in the planet's atmosphere using existing strategies for propulsion and mobility.

BREEZE is still a long way from actually dipping in and out of Venusian clouds, but this acknowledgment and award from NASA means it's one step closer along the path to development.

SpaceX launched a 3-ton shipment to the International Space Station on Thursday, including "mighty mice" for a muscle study, a robot sensitive to astronauts' emotions and a miniature version of a brewery's malt house. The Dragon capsule also is delivering holiday goodies for the six station residents. SpaceX recovered the new booster on a barge just off the coast in the Atlantic several minutes following liftoff so it could be reused.

Aerojet Rocketdyne signs on the bottom line to build hardware for moon missions

REDMOND, Wash. - Representatives of Aerojet Rocketdyne and Lockheed Martin put their signatures on a contract for up to $170 million worth of rocket hardware that'll be installed on Orion spacecraft heading to the moon - with dozens of employees who'll actually build that hardware watching the proceedings. "These are the things you're going to be talking to your grandchildren about," Cheryl Rehm, Aerojet Rocketdyne's senior director of Redmond programs, told company employees here at today's signing ceremony. The ceremony highlighted Redmond's role in NASA's Artemis moon landings. "For the more than 400 employees sitting here in Redmond, there's more… Read More

NASA's sun-skimming spacecraft, the Parker Solar Probe, is surprising scientists with its unprecedented close views of our star. NASA's Nicola Fox compared this unexpected switchback phenomenon to the cracking of a whip. "They're striking and it's hard to not think that they're somehow important in the whole problem," said Stuart Bale of the University of California, Berkeley, who was part of the team.

Boeing has delayed its first test flight of its Starliner crew capsule to the International Space Station. NASA said Tuesday that the two-day postponement was caused by problems with ground equipment at the Cape Canaveral pad. Both the Starliner and United Launch Alliance's Atlas V rocket are healthy, officials said.

Indian engineer 'interested in space' helps Nasa locate debris of Delhi's crashed Moon rover

Nasa has credited a 33-year old Indian engineer and computer programmer with helping it pinpoint the debris of India's unmanned exploratory lunar spaceship that crashed on the moon in September.   The Vikram moon lander was scheduled to make a 'soft landing' on the moon's South Pole on 7 September but the vehicle crash landed some 370 miles from its designated location due to a technical error. Some weeks later Nasa announced the discovery of the lander and its "associated debris field" but was unable to precisely locate it.     The US space agency ascribed its success in detecting debris of the Vikram moon lander to Shanmuga Subramanian, a technical architect at Lennor India...
