WASHINGTON — SpaceX launched its fourth Starship prototype in less than four months March 30, only to have the vehicle apparently crash once again.
The Starship SN11 vehicle lifted off at approximately 9 a.m. Eastern from the company’s Boca Chica, Texas, test site, despite heavy fog that made it all but impossible to see the vehicle ascend.

WASHINGTON — Virgin Galactic revealed its latest suborbital spaceplane March 30, a vehicle that looks similar to its existing SpaceShipTwo but incorporates significant structural improvements.
The company unveiled the first of what it calls the “Spaceship III” line of vehicles, called VSS Imagine.
Photosynthesis could be as old as life itself
Monday, 29 March 2021 11:23 Write a comment
Researchers find that the earliest bacteria had the tools to perform a crucial step in photosynthesis, changing how we think life evolved on Earth.
The finding also challenges expectations for how life might have evolved on other planets. The evolution of photosynthesis that produces oxygen is thought to be the key factor in the eventual emergence of complex life. This was thought to take Direct observations confirm that humans are throwing Earth's energy budget off balance

Earth is on a budget - an energy budget. Our planet is constantly trying to balance the flow of energy in and out of Earth's system. But human activities are throwing that off balance, causing our planet to warm in response.
Radiative energy enters Earth's system from the sunlight that shines on our planet. Some of this energy reflects off of Earth's surface or atmosphere back into space. Astronomy and Landscape in the city of Caral, the oldest city in the Americas

Following the selection of the first Scout satellite mission last December, ESA has also given the greenlight to start negotiations with Surrey Satellite Technology Ltd in the UK to lead the development of the second Scout mission – HydroGNSS.
SpaceX postpones Starship test flight
Monday, 29 March 2021 04:58 Write a comment
SpaceX postponed a test flight Monday for the company's Starship moon and Mars rocket in Boca Chica, Texas.
Company CEO Elon Musk posted on Twitter that the flight was called off because a federal inspector couldn't reach the remote site in time. Musk calls it Starbase, and it is about 23 miles east of Brownsville.
"Postponed to no earlier than tomorrow [Tuesday]" Musk wrote. SwRI scientists discover a new auroral feature on Jupiter

The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA's Juno spacecraft has detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. SwRI scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions.

A paper by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Director Ooguri Hirosi and Project Researcher Matthew Dodelson on the string theoretical effects outside the black hole photon sphere has been selected for the "Editors' Suggestion" of the journal Physical Review D. Their paper was published on March 24, 2021.

A new black hole breaks the record - not for being the smallest or the biggest - but for being right in the middle.
The recently discovered 'Goldilocks' black hole is part of a missing link between two populations of black holes: small black holes made from stars and supermassive giants in the nucleus of most galaxies.

Scientists reported new research results today suggesting that artificial objects in orbit around the Earth are brightening night skies on our planet significantly more than previously understood.
The research, accepted for publication in Monthly Notices of the Royal Astronomical Society: Letters, finds that the number of objects orbiting Earth could elevate the overall brightness of the n
