Asteroid discovery suggests ingredients for life on Earth came from space

March 21 (Reuters) — Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago.

Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Space Agency’s Hayabusa2 spacecraft from two sites on Ryugu in 2019. Uracil is one of the chemical building blocks for RNA, a molecule carrying directions for building and operating living organisms. Niacin, also called Vitamin B3 or nicotinic acid, is vital for their metabolism.

The Ryugu samples, which looked like dark-gray rubble, were transported 155 million miles (250 million km) back to Earth and returned to our planet’s surface in a sealed capsule that landed in 2020 in Australia’s remote outback for analysis in Japan.

Radical NASA Propulsion Concept Could Reach Interstellar Space in Under 5 Years

A newly proposed propulsion system could theoretically beam a heavy spacecraft to outside the confines of our Solar System in less than 5 years – a feat that took the historic Voyager 1 probe 35 years to achieve.

The concept, known as ’pellet-beam’ propulsion, was awarded an early-stage US$175,000 NASA grant for further development earlier this year.

To be clear, the concept currently doesn’t exist much beyond calculations on paper, so we can’t get too excited just yet.

Hubble telescope unravels the weather secrets of Jupiter and Uranus

The Hubble Space Telescope’s remarkable observations shed light on the seasonal shifts and atmospheric conditions of Jupiter and Uranus.

The Hubble Space Telescope has been fundamental in unraveling the mysteries of our solar system. The telescope is a celestial weather observer that studies the changing atmosphere of giant gaseous planets. By observing climatic variations, scientists are unlocking new understanding about the dynamic weather systems of these gas giants, paving the way for a deeper understanding of our solar system.

Recently, it disclosed exquisite details about the changing weather patterns and seasonal shifts on Jupiter and Uranus.

Relativity’s first 3D-printed rocket launches successfully but fails to reach orbit

Relativity Space, a 3D-printing specialist, launched the inaugural flight of its Terran 1 rocket late on Wednesday night, which successfully met some mission objectives before failing to reach orbit.

Terran 1 lifted off from LC-16, a launchpad at the U.S. Space Force’s facility in Cape Canaveral, Florida, and flew for about three minutes. While the rocket cleared a key objective — passing the point of maximum atmospheric pressure during an orbital launch, known as Max Q — its engine sputtered and shut down early, shortly after the second stage separated from the first stage, which is the larger, lower portion of the rocket known as the booster.

Relativity launch director Clay Walker confirmed that there was an “anomaly” with the upper stage. The company said it will give “updates over the coming days” after analyzing flight data.

RNA component found in asteroid sample

Interesting results from the Japanese Hayabusa2 spacecraft — molecules needed for life were found in samples from the asteroid Ryugu.

The mission will now continue until at least 2031.

The RNA building block uracil has been found on asteroid 162,173, along with niacin, both important in the development of life.

The Webb Telescope Is So Powerful, It Spotted a Dust Storm on a Planet in a Different Star System

For the first time ever, a dust storm has been observed outside of our Solar System — and naturally, it was the powerful James Webb Space Telescope that made the discovery.

A press release on the Space Telescope Science Institute’s Webb-site details the JWST-detected storm, which took place on exoplanet VHS 1,256 b, a “massive brown dwarf” planet located about 40 lightyears from Earth.

“Ever had hot sand whip across your face?” the press release quips. “That’s a soothing experience compared to the volatile conditions discovered high in the atmosphere of planet VHS 1,256 b.”

The Six Million Dollar Man is an American science fiction and action television series about a former astronaut, Colonel Steve Austin, portrayed by American actor Lee Majors. Austin has superhuman strength due to bionic implants and is employed as a secret agent by a fictional U.S. government office named OSI The series was based on the Martin Caidin novel Cyborg, which. was the working title of the series during pre-production.

Following three television pilot movies, which all aired in 1973, the The Six Million Dollar Man aired on the ABC network as a regular episodic series for five seasons from 1974 to 1978. Steve Austin became a pop culture icon of the 1970s. A spin-off television series, The Bionic Woman, featuring the lead female character Jaime Sommers, ran from 1976 to 1978 (and was the subject of a remake in 2007). Three television movies featuring both bionic characters were also produced from 1987 to 1994.

When NASA astronaut Steve Austin is severely injured in the crash of an experimental lifting body aircraft, he is “rebuilt” in an operation that costs six million dollars. His right arm, both legs and the left eye are replaced with “bionic” implants that enhance his strength, speed and vision far above human norms: he can run at speeds of 60 mph (97 km/h), and his eye has a 20:1 zoom lens and infrared capabilities, while his bionic limbs all have the equivalent power of a bulldozer. He uses his enhanced abilities to work for the OSI (Office of Scientific Intelligence) as a secret agent.
