Venus has almost become a “forgotten planet”, with only one space mission carried out there in the last 30 years. But the recent resurgence of interest in Earth’s closest neighbor led NASA and ESA to commit to three new missions to Venus, all set to launch in the early 2030s. ESA’s EnVision Venus mission is scheduled to take high-resolution optical, spectral and radar images of the planet’s surface. But to do so, the van-sized spacecraft would need to perform a special maneuver called aerobraking to gradually slow down and lower its orbit through the planet’s hot, thick atmosphere. Aerobraking uses atmospheric drag to slow the spacecraft and EnVision will make thousands of passes through Venus’ atmosphere over about two years. Aerobraking maneuvers are a necessity for the mission. Remove All Ads in Universe Today Join our Patreon for only $3!

Bindi Irwin has cut her famous long blonde hair. The Wildlife Warrior made its dramatic new debut celebrating its 24th birthday on Sunday with a glamorous photo shoot on the Sunshine Coast. The image shows Bindi in a shoulder-length bob posing outdoors in the bush with her husband Chandler Powell, 25, and their daughter Grace, one. Bindi Irwin has cut her famous long blonde hair.

How many storages have high grating – 90 percent or more – varying wind and solar requirements to ensure there is enough supply to meet demand? This is a hot topic inside and outside the energy circle. One common theory – often pushed by the nuclear and fossil fuel lobbies, and the former Coalition government – ​​is that you should match each kW of wind and solar capacity to an equivalent amount of storage. The CSIRO says the idea is wrong, and Australia will only need to install a fraction of the storage for every kW of renewable energy – between one-fifth and one-third – to meet demand. “Such a conclusion would substantially overestimate the need for storage capacity,” said CSIRO in an updated version of the GenCost report, a landmark annual document that tracks the costs of comparable energy technologies, and in the case of wind and solar, their storage and transmission. needs too. The reason for this, says CSIRO, is that although the generation mix is ​​changed, and significantly

Notice the Earth on the far right. Image via NASA/Wikimedia Commons. Earthly life requires water. So scientists contemplating life outside our solar system have traditionally thought of watery exoplanets, similar to our own aquatic world. An exoplanet that is similar to Earth – in terms of atmosphere, distance to stars, mass, etc. – suggests a possible habitable world. But scientists said in late June 2022 that long-term liquid water would not have occurs under conditions similar to Earth. Exoplanets can be a little bigger and may not even be located near a star! The new study comes from researchers at the University of Bern, the University of Zürich and PlanetS’s National Center for Competence in Research (NCCR). This suggests that several different exoplanets from Earth may be able to retain liquid
