A new rocket design under production by NASA won't be ready for a scheduled June 2020 launch, the agency's administrator told Congress on Wednesday. Jim Bridenstine told the Senate Commerce, Science and Transportation Committee that a mission to send an unmanned capsule around the moon next year, a three-week test flight for a manned mission planned for 2023, may need to be delayed unless the agency decides to go with privately owned rockets for the launch.

The SpaceX commercial astronaut capsule has splashed down successfully in the Atlantic Ocean, marking a significant step in Nasa’s quest to resume manned space flight from the US. Footage of the landing shows the capsule hitting the water gently under four billowing red and white parachutes. A boat, the GO Searcher, was waiting to recover the capsule, which splashed down about 280 miles (450 km) from Cape Canaveral in Florida.

A sleek new American-built capsule with just a test dummy aboard docked smoothly with the International Space Station on Sunday in a big step toward putting the U.S. back in the business of launching astronauts. The white, bullet-shaped Dragon capsule, developed by Elon Musk's SpaceX company under contract to NASA, closed in on the orbiting station nearly 260 miles above the Pacific Ocean and, flying autonomously, linked up on its own, without the help of the robotic arm normally used to guide spacecraft into position.

NASA has some good news, the world is a greener place today than it was 20 years ago. What prompted the change? Well, it appears China and India can take the majority of the credit. In contrast to the perception of China and India's willingness to overexploit land, water and resources for economic gain, the countries are responsible for the largest greening of the planet in the past two decades. The two most populous countries have implemented ambitious tree planting programs and scaled up their implementation and technology around agriculture.

WHEN it comes to illustrating humanity’s achievements in space, NASA’s back catalogue is as good as it gets. The images here are all part of a book tracing the agency’s 60 years of existence using more than 400 photographs. The big launches, moon landings, starscapes and Martian panoramas all make the cut, alongside plenty of striking views from behind the scenes, images that give a human scale to NASA’s vast technological endeavours.

Greenland’s ice sheet is the second largest body of ice in the world, so scientists are naturally interested in how it’s changing with the climate and what’s under there. Recent studies of the ice sheet with radar revealed something unexpected: an impact crater. What’s more unexpected than an impact crater? A second impact crater. NASA says it just spotted a second crater just over a hundred miles from the first one, and the team believes they formed at different times.

NASA is finally saying goodbye to its Opportunity rover on Mars after spending nearly a year trying to reestablish communication with the silent robot. A team of engineers at NASA’s Jet Propulsion Laboratory (JPL) sent one final radio command to the rover last night but did not receive a response. Now, NASA will stop trying to communicate with Opportunity, effectively bringing the rover’s 15-year mission on Mars to an end.

Not every child will be an astronaut, but all children have dreams that can benefit from hard work and parental support. Lamp says she tried to encourage her daughter to follow her passions and treat setbacks as opportunities for growth. Children should explore, she says, and take risks and try new things and fail and try again. "I don't like to see kids over-structured," she says. "They need to be creative."

On Jan. 19, 2019, just 161 days after its launch from Cape Canaveral Air Force Station in Florida, NASA’s Parker Solar Probe completed its first orbit of the Sun, reaching the point in its orbit farthest from our star, called aphelion. The spacecraft has now begun the second of 24 planned orbits, on track for its second perihelion, or closest approach to the Sun, on April 4, 2019.

Hacking NASA’s Curiosity rover let it measure Martian gravity, even though it has no scientific instruments designed to do so. The measurements revealed a surprise at Gale crater. We can use gravity to probe the interior structure of a planet because the gravitational pull of a particular area depends on the type and density of the rocks there.
