And wherever humans go, they’ll be taking satellite constellations with them to moon and Mars.

NASA may have sidelined the Lunar Gateway for a return mission to the Moon, but it is not stopping the momentum. NASA has awarded several contracts for the Lunar Gateway including the most recent one to SpaceX. This demonstrates the growing capabilities of New Space companies to capture contracts and complete missions.
“This contract award is another critical piece of our plan to return to the Moon sustainably. The Gateway is the cornerstone of the long-term Artemis architecture and this deep space commercial cargo capability integrates yet another American industry partner into our plans for human exploration at the Moon in preparation for a future mission to Mars.”
NASA Administrator Jim Bridenstine in a press release statement about the award to SpaceX.
The United Launch Alliance Atlas 5 rocket was launched from Cape Canaveral, Florida.
The launch was delayed by an hour due to a ground hydraulics issue.
The public viewing area was closed to the public due to the coronavirus pandemic.
But as we prepare for longer journeys that will return humans to the Moon and possibly send them to Mars within the near future, scientists are working hard to measure the effects of spaceflight on the human body in order to help mitigate them for those longer missions.
To see distant stars and planets, astronomers must first calibrate their equipment to compensate for Earth’s blurry atmosphere — and that’s a whole lot easier said than done. In fact, to pull it off, they have to actually create artificial stars, dubbed ‘guide stars’, using really, really big lasers.
Now, researchers from the European Southern Observatory’s (ESO) Paranal Observatory in Chile have created the most powerful one to date — a system they call the Four Laser Guide Star Facility (4LGSF).
The new system, which has been tested since last September, works by shooting four 29.9-centimetre (11.8-inch), 22-watt beams into the atmosphere to basically mark the sky.

Parachutes are plaguing space programs. SpaceX doesn’t like Parachutes. They are difficult to design, hard to package, and easy to damage. The larger the mass of the spacecraft, the more effort to slow down. Larger, more efficient, complex parachute systems are needed. Several failures have hit the industry over the last few years, including SpaceX Crew Dragon, ESA ExoMars, Boeing CST-100, and the NASA Orion to name a few.
How do parachutes work and why are they hard?
The bubble concept could explain one of the strangest mysteries plaguing astrophysics: Why can’t we tell how fast the universe is expanding?
