A NASA robotic rover is nearing completion ahead of a journey next year to search for evidence of past life on Mars and lay the groundwork for the space agency’s mission to send humans into deep space.
The US space agency on Friday showed off its Mars 2020 rover, whose official name is to be chosen early next year.
NASA would in February ship the rover to Florida’s John F. Kennedy Space Center, where its three sections are to be fully assembled. A July launch would send the rover to a dry lake bed on Mars that is bigger than the island of Manhattan.

The six-wheeled, car-sized rover is to scour the base of Mars’ Jezero Crater, a 250m-deep crater thought to have been a lake the size of Lake Tahoe, once the craft lands in February 2021. The crater is believed to have an abundance of pristine sediments about 3.5 billion years old that scientists hope will hold fossils of Martian life.
“The trick, though, is that we’re looking for trace levels of chemicals from billions of years ago on Mars,” deputy project manager Matt Wallace told reporters.
The rover is to collect up to 30 soil samples to be picked up and returned to Earth by a future spacecraft planned by NASA.
“Once we have a sufficient set, we’ll put them down on the ground and another mission, which we hope to launch in 2026, will come, land on the surface, collect those samples and put them into a rocket, basically,” Wallace said.
Humans have never before returned sediment samples from Mars.
The findings of the rover’s research would be crucial to future human missions to the red planet, including the ability to make oxygen on the surface of Mars, Wallace said.
The rover is to carry equipment that can turn carbon dioxide, which is pervasive on Mars, into oxygen for breathing and as a propellant.
If successful, Mars 2020 would mark NASA’s fifth Martian rover to carry out a soft landing, having learned crucial lessons from the most recent rover, Curiosity, that landed on the planet’s surface in 2012 and continues to traverse a Martian plain southeast of the Jezero Crater.
Airlines in Australia, Hong Kong, India, Malaysia and Singapore yesterday canceled flights to and from the Indonesian island of Bali, after a nearby volcano catapulted an ash tower into the sky. Australia’s Jetstar, Qantas and Virgin Australia all grounded flights after Mount Lewotobi Laki-Laki on Flores island spewed a 9km tower a day earlier. Malaysia Airlines, AirAsia, India’s IndiGo and Singapore’s Scoot also listed flights as canceled. “Volcanic ash poses a significant threat to safe operations of the aircraft in the vicinity of volcanic clouds,” AirAsia said as it announced several cancelations.

Farmer Liu Bingyong used to make a tidy profit selling milk but is now leaking cash — hit by a dairy sector crisis that embodies several of China’s economic woes. Milk is not a traditional mainstay of Chinese diets, but the Chinese government has long pushed people to drink more, citing its health benefits. The country has expanded its dairy production capacity and imported vast numbers of cattle in recent years as Beijing pursues food self-sufficiency. However, chronically low consumption has left the market sloshing with unwanted milk — driving down prices and pushing farmers to the brink — while
China has built a land-based prototype nuclear reactor for a large surface warship, in the clearest sign yet Beijing is advancing toward producing the nation’s first nuclear-powered aircraft carrier, according to a new analysis of satellite imagery and Chinese government documents provided to The Associated Press. There have long been rumors that China is planning to build a nuclear-powered aircraft carrier, but the research by the Middlebury Institute of International Studies in California is the first to confirm it is working on a nuclear-powered propulsion system for a carrier-sized surface warship. Why is China’s pursuit of nuclear-powered carriers significant? China’s navy is already
‘SIGNS OF ESCALATION’: Russian forces have been aiming to capture Ukraine’s eastern Donbas province and have been capturing new villages as they move toward Pokrovsk Ukrainian Commander-in-Chief Oleksandr Syrskyi on Saturday said that Ukraine faced increasing difficulties in its fight against Moscow’s invasion as Russian forces advance and North Korean troops prepare to join the Kremlin’s campaign. Syrskyi, relating comments he made to a top US general, said outnumbered Ukrainian forces faced Russian attacks in key sectors of the more than two-and-a-half-year-old war with Russia. Ukrainian President Volodymyr Zelenskiy in a nightly address said that Ukraine’s military command was focused on defending around the town of Kurakhove — a target of Russia’s advances along with Pokrovsk, a logistical hub to the north. He decried strikes
