Four astronauts from the International Space Station (ISS) came back to Earth on Sunday in what was the first nighttime splashdown by a U.S. crew since the Apollo moonshot in 1968.

China aims to construct a national-level space laboratory by 2022, as the country successfully launched its Long March-5B rocket carrying the core module of China’s space station Tianhe on Thursday, indicating that China is on track for its space ambitions.
China Media Group (CMG) talked on Friday with Zhong Hongen, deputy chief engineer of space application system at China’s Manned Space Flight Project, to find out the exact scientific experiments and available facilities there in the outer space, as well as the related effects on our daily lives.
NASA’s long-delayed Space Launch System (SLS) is finally beginning to take shape. Following a number of impressive engine tests, the various components of the first full spacecraft have all arrived at NASA’s Kennedy Space Center, including the newly arrived core stage. That part of the mega-rocked floated up to the spaceport on a 310-foot barge earlier this week.
The Space Launch System was envisioned as a replacement for the aging Space Shuttle, and one that could help humanity move beyond low-Earth orbit once again. Since the end of the Apollo program, we’ve been limited to hovering over our little blue marble, but the SLS has enough power to send crewed spacecraft back to the moon. That’s why it’s at the heart of the Artemis program. In the coming years, Artemis will deliver the first human explorers to the moon’s surface in half a century, and among them will be the first woman and person of color to walk on the lunar surface.
Before arriving at KSC on the agency’s Pegasus barge, the 212-foot core stage was at the Stennis Space Center in Mississippi. That’s where NASA ran the recent Green Run tests. The first static fire test in January ended early, after approximately one minute. NASA later confirmed this was the result of a failsafe system being triggered. In the subsequent March test, the rocket’s RS-25 engines ran for more than eight minutes, matching what they’ll have to do when the rocket launches for real.
“For those of you enrolled in our frequent flyer program, you’ve earned 68 million miles on this voyage,” SpaceX’s Mission Control radioed.
CAPE CANAVERAL, Fla. — SpaceX safely returned four astronauts from the International Space Station on Sunday, making the first U.S. crew splashdown in darkness since the Apollo 8 moonshot.
The Dragon capsule parachuted into the Gulf of Mexico off the coast of Panama City, Florida, just before 3 a.m., ending the second astronaut flight for Elon Musk’s company.

Sorry, we’re having trouble playing this video.
Are the space junk and carbon footprint issues of extra-terrestrial endeavours solvable?
SpaceX and NASA are targeting Saturday, May 1 at 8:35 p.m. EDT, or 00:35 UTC on May 2, for Dragon to autonomously undock from the International Space Station (ISS) and splashdown off the coast of Florida on Sunday, May 2 at approximately 2:57 a.m. EDT, 6:57 UTC, completing its first six-month operational mission to the Station.
A series of departure burns will move Dragon away from the orbiting laboratory, followed by the vehicle jettisoning the trunk to reduce weight and mass to help save propellant for the deorbit burn. Once complete, Dragon will re-enter Earth’s atmosphere and deploy its two drogue and four main parachutes in preparation for a soft water landing.
Crew-1, which launched to the space station in November, will head home in the capsule called Resilience.
Voyager 2 joined Voyager 1 outside the heliosphere one year ago. Now, five new papers reveal what it has found out there.
Only two of humanity’s spacecraft have left the Solar System: NASA’s Voyager 1 and Voyager 2. Voyager 1 left the heliosphere behind in 2012, while Voyager 2 did the same on Nov. 5th, 2018. Now Voyager 2 has been in interstellar space for one year, and five new papers are presenting the scientific results from that one year.
The heliosphere is a bubble-shaped region of space with our Sun in the center. Think of it as an inflated cavity full of plasma that comes from the Sun. The edge of the bubble is where the plasma from our Sun gives way to the interstellar medium (ISM.) Voyager 2 left the heliosphere behind and entered interstellar space at about 18 billion km (11 billion miles) from Earth.

No word on price yet.
Jeff Bezos’ Blue Origin is about to start selling seats on its New Shepard spacecraft, which is designed to people on brief trips to suborbital space.
The HI-SEAS mock extraterrestrial base is part of an intensifying effort to get humans ready for living on other worlds, which could well be soon. NASA recently selected SpaceX as the company to build its Artemis lunar lander. At some point, our visits will have to become stays if human space exploration is to go beyond its 20th-century heyday.
