Each of the six Apollo missions that landed on the Moon carried an array of science experiments designed to tell us about our satellite and its environment. The Moon rocks the astronauts brought back to Earth deservedly received the most attention, but the other experiments proved their worth as well.

SpaceX’s Dragon cargo capsule has made its way back from the International Space Station, completing the private launcher’s seventeenth resupply mission for the orbital research facility. Commercial Resupply Services mission 17 (aka CRS-17 if you’re down to acronym) launched on May 4, its first backup window after an initial mission scrub. The Dragon’s cargo for this one included 5,500 lbs of both supplies for the astronauts, as well as materials used for ongoing experiments and research aboard the station. https://techcrunch.com/2019/06/03/spacex-dragon-capsule-returns-from-space-station-resupply-mission/

SpaceX launched the first 60 satellites for an internet constellation that could ultimately number 12,000 on a Falcon 9 rocket Thursday night. The 60 satellites mark the beginning of SpaceX’s deployment of a global internet megaconstellation intended to generate more revenue to fuel the company’s interplanetary ambitions.

At the center of a galaxy more than 55 million light-years away, there's a supermassive black hole with the mass of several billion suns. And now, for the first time ever, we can see it. Astrophysicist Sheperd Doeleman, head of the Event Horizon Telescope collaboration, speaks with TED's Chris Anderson about the iconic, first-ever image of a black hole -- and the epic, worldwide effort involved in capturing it.

Astronomers may have spotted a neutron star being swallowed by a black hole for the first time, marked by a belch of gravitational waves rippling across the cosmos.

This morning, astronauts on the International Space Station successfully grappled Northrop Grumman Corp.'s Cygnus spacecraft with the station's robotic arm, snagging 7,600 lbs (3,447 kilograms) of cargo, just in time for Easter.

The world’s largest airplane took flight for the first time ever on Saturday morning. Built by rocket launch company Stratolaunch, the 500,000-pound plane with a 385-foot wingspan lifted off shortly after 10AM ET from Mojave Air and Space Port in Mojave, California. It was a critical first test flight for the aircraft, designed to launch rockets into orbit from the air. The inaugural flight lasted for 150 minutes, according to the company, after which the plane safely landed.

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy. It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster". The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. Details have been published today in Astrophysical Journal Letters.

In the past three decades, almost 4,000 planet-like objects have been discovered orbiting isolated stars outside the solar system (exoplanets). Beginning in 2011, it was possible to use NASA's Kepler Space Telescope to observe the first exoplanets in orbit around young binary systems of two live stars with hydrogen still burning in their core.

On March 29, NASA will have the first all-female spacewalk in the agency's history. Conducting the spacewalk will be astronauts Anne McClain and Christina Koch. On the ground, they will be supported by an all-female crew at Houston's Johnson Space Center.

SpaceX's first Crew Dragon spacecraft cast off from the International Space Station for the return to Earth Friday (March 8th) as it wrapped up a historic test flight for NASA. The Crew Dragon undocked from the space station at 2:32 a.m. EST (0732 GMT) as both spacecraft sailed 253 miles (407 kilometers) above Africa near Sudan. Its departure ended five days linked at the station following an arrival on Sunday (March 3) during a high-profile Demo-1 demonstration mission. The spacecraft is scheduled to splash down in the Atlantic Ocean, near Florida's eastern coast, at 8:45 a.m. EST (1345 GMT).

Just a day after launching to orbit, SpaceX’s new Crew Dragon capsule automatically docked to a port on the International Space Station this morning — a critical part of its current test flight. This docking maneuver is something the capsule will have to do routinely in the future, when it starts transporting astronauts to and from the ISS.

The most detailed images of Ultima Thule -- obtained just minutes before the spacecraft's closest approach at 12:33 a.m. EST on Jan. 1 -- have a resolution of about 110 feet (33 meters) per pixel. Their combination of higher spatial resolution and a favorable viewing geometry offer an unprecedented opportunity to investigate the surface of Ultima Thule, believed to be the most primitive object ever encountered by a spacecraft.

Late Tuesday night, scientists at NASA's Jet Propulsion Laboratory sent their final data uplink to the Opportunity rover on Mars. Over this connection, via the Deep Space Network, the American jazz singer Billie Holiday crooned "I'll Be Seeing You". But in the end, no response came. Opportunity would finally be declared dead on Sol 5352, as in five thousand, three hundred, and fifty-two days on Mars.

The appearance of a single green leaf hinted at a future in which astronauts would grow their own food in space, potentially setting up residence at outposts on the moon or other planets. Now, barely after it had sprouted, the cotton plant onboard China’s lunar rover has died. The plant relied on sunlight at the moon’s surface, but as night arrived at the lunar far side and temperatures plunged as low as -170C, its short life came to an end.

Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada. The precise nature and origin of the blasts of radio waves is unknown. Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away.

Three new planets and six supernovae outside our solar system have been observed by Nasa’s planet-hunting Tess mission in its first three months. Since it started surveying the sky in July, the MIT-led Transiting Exoplanet Survey Satellite project has identified Pi Mensae b, a “super-Earth” that travels around its star every six days, and LHS 3844b, a rocky world with an orbit of only 11 hours.

Humanity just planted its flag on the far side of the moon. China's robotic Chang'e 4 mission touched down on the floor of the 115-mile-wide (186 kilometers) Von Kármán Crater Wednesday night (Jan. 2), pulling off the first-ever soft landing on the mysterious lunar far side.

A Chinese spacecraft could become the first ever to land on the “far side” of the moon tomorrow, in a milestone for human space exploration. The China National Space Administration (CNSA) is aiming to land the craft in the unexplored South Pole-Aitken basin, the largest, oldest, deepest, crater on the moon’s surface. The robotic probe, Chang’e 4, entered an elliptical path around the moon last weekend, drawing as close as 15km (9 miles) from the surface. China’s mission control has not confirmed a time for the touchdown attempt but reports in state-run media suggested it would be early Thursday morning UK time.
