China Aerospace Science and Industry Corp, a major defense contractor, plans to produce a reusable aerospace plane and put it into commercial flight by 2030.
The plane will take off from and land on a conventional runway like a jetliner and will be capable of flying in near space or even into outer space. The low-cost aircraft will have high-quality safety features and will be used to fulf Icy clouds could have kept early Mars warm enough for rivers and lakes, study finds

One of the great mysteries of modern space science is neatly summed up by the view from NASA's Perseverance, which just landed on Mars: Today it's a desert planet, and yet the rover is sitting right next to an ancient river delta.
The apparent contradiction has puzzled scientists for decades, especially because at the same time that Mars had flowing rivers, it was getting less than a third Star light, star bright as explained by math

Not all stars shine brightly all the time. Some have a brightness that changes rhythmically due to cyclical phenomena like passing planets or the tug of other stars. Others show a slow change in this periodicity over time that can be difficult to discern or capture mathematically. KAUST's Soumya Das and Marc Genton have now developed a method to bring this evolving periodicity within the framewo Probing deep space with Interstellar

When the four-decades-old Voyager 1 and Voyager 2 spacecraft entered interstellar space in 2012 and 2018, respectively, scientists celebrated. These plucky spacecraft had already traveled 120 times the distance from the Earth to the sun to reach the boundary of the heliosphere, the bubble encompassing our solar system that's affected by the solar wind. The Voyagers discovered the edge of the bubble but left scientists with many questions about how our Sun interacts with the local interstellar medium. The twin Voyagers' instruments provide limited data, leaving critical gaps in our understanding of this region.
Blue Origin protests NASA Human Landing System award

TAMPA, Fla. — U.S.-based startup Swarm Technologies and 28-year old Orbcomm, both pursuing the fast-growing market for connecting Internet of Things (IoT) sensors to satellites, are locked in a regulatory tussle over plans to expand overseas.
Orbcomm is challenging a letter the Federal Communications Commission (FCC) sent March 10, which aimed to clarify how it and Swarm would share spectrum in Very High Frequency (VHF) bands worldwide.

The astronauts flying SpaceX back to Earth this week urged boaters to stay safe by staying away from their capsule's splashdown in the Gulf of Mexico.
NASA and SpaceX are promising more Coast Guard patrols and fewer pleasure boaters for Wednesday afternoon's planned splashdown off the Florida panhandle coast near Tallahassee—the company's second return of a crew.

A timelapse from various angles of the launch of SpaceX Falcon 9 with Crew Dragon Endeavour leaving Earth from Kennedy Space Center in Florida, USA.
The rocket lifted off at 10:49 BST (11:49 CEST, 05:49 local time) on 23 April 2021 from Launchpad 39A in Cape Canaveral with ESA astronaut Thomas Pesquet, NASA astronauts Megan McArthur and Shane Kimbrough, and JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide.
On 24 April at 11:08 CEST the Crew-2 caught up with the International Space Station and docked with its Harmony module, marking the start of Thomas’ Alpha mission.

NOAA's GOES-T completes solar array deployment test
Monday, 26 April 2021 10:54 Write a comment
On March 3, 2021, engineers completed a successful test deployment of the GOES-T solar array as part of a series of tests to prepare the satellite for a planned December 2021 launch.
This critical test verified that the satellite's large, five-panel solar array—which is folded up when the satellite is launched—will properly deploy when GOES-T reaches geostationary orbit. During this test, engineers unfurled the five panels on rails that simulated the zero-gravity environment of space. Each solar panel is approximately 13 feet tall by 4.5 feet wide and weighs approximately 45 pounds.
Once GOES-T reaches orbit, the deployed solar panels will form a single solar array wing that will rotate once per day to continuously point its photovoltaic (solar) cells toward the sun. These cells will convert solar energy into electricity to power the entire satellite, including the instruments, computers, data processors, sensors, and telecommunications equipment. The solar array will generate more than 5,000 watts of power for the satellite.
