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!

Australians pay about 20 cents per liter more for diesel than they should, consumer advocates say. And they said there seemed to be no good reason for that. Federal Treasurer Jim Chalmers said Australians were “really dirty” about higher fuel prices. While prices have declined, experts say diesel prices have not fallen enough. But retailers say there is always a lag between the drop in oil prices seen at the pump. Even if you don’t own a diesel vehicle, you may be affected by the price of diesel. That’s because it’s the fuel of choice for industry — transportation, agriculture, shipping, and mining — which means there are after-effects for the economy. Why is diesel so much more expensive than gasoline? Oil prices soared earlier this year after Russia was sanctioned for its invasion of Ukraine. Diesel prices rose more than gasoline due to various factors including higher demand due to the COVID-19 economic recovery and less supply from Russia. Russia is on...

The jet was in the final stages of a nearly six-hour flight across Brisbane (BNE) when Perth air traffic controllers put the plane into an extended hold period. But with fuel running low, the pilot made the unusual call of a fuel mayday. Extended containment beyond Perth pushed aircraft closer to the minimum required fuel reserves The incident involved flight QF933 operated by VH-VZO, an 11-year-old Boeing 737-800. The narrow-bodied aircraft are the workhorses of Qantas’ domestic network, crossing Australia and rarely causing problems. The Australian Civil Aviation Safety Authority (CASA) requires flights to take off with fuel reserves at least 30 m...

A regional airline has temporarily cut some Tasmanian services as a result of rising fuel costs. Key points: Sharp Airlines has temporarily suspended Saturday services to King Island and Flinders, as well as Wednesday services from Essendon to King Island Airlines say facing rising fuel costs, the only other alternative is to increase ticket prices Flights are scheduled to restart in September Sharp Airlines said the price of aviation turbine fuel had increased by more than $1 per liter in 12 months, 40 cents of which came in the past two months. Managing Director Malcolm Sharp said the airline had chosen to reduce flights rather than charge travelers. “For our customers, we try to find ways to make it at least less painful,” he said. “The easiest thing to do is raise prices, but we think that will have a bad impact on demand. “This is a difficult time.” The war in Ukraine has pushed up oil prices around the world.

Australia will soon produce synthetic gasoline and LPG, thanks to a new facility under construction in northwestern Tasmania. 0 See 3 pictures Tasmania will soon be home to Australia’s first synthetic fuel plant. Global synthetic fuel company HIF – which has received financial support from Porsche – has announced the establishment of HIF Tasmania, with the island nation to produce up to 100 million liters of carbon-neutral synthetic fuel per year. Synthetic fuels (or eFuels) are produced by harvesting CO2 from the environment, and then using renewable electricity to make hydrogen and combining it with the captured CO2 to produce different products used in cars and airplanes. The idea is that vehicles will only emit CO2 that has been captured and removed from the environment, rather than releasing new CO2 into the atmosphere by burning hydrocarbons derived from oil. HIF Tasmania said it would produce ‘eGasoline’ as a substitute for unleaded gasoline for use in cars, as ...

Australian drivers have been suffering from bowser pain this year, with petrol prices topping $2 per liter. That’s despite the federal government’s move earlier in March to half of the fuel excise tax in a bid to ease financial pressure on drivers. But the cuts are not forever and the reduced rates are coming to an end. So what does it mean for drivers when they are again saddled with full excise duty in about three months? What is a fuel tax? Every time Australians buy gasoline, they contribute to a pool of funds that the federal government uses for roads and infrastructure. Simply put, you usually pay 44.2 cents in tax for every liter of fuel you buy — included in the price at Bowser. Excise duty was halved on March 30 to 22.1 cents per liter. Why did the Morrison government cut fuel taxes? The move is aimed at battling a spike in gasoline prices to ease cost-of-living pressures. The government estimates cutting fuel excise taxes will save midsize car owners about $13 when...
