NASA Chooses SpaceX To Land Next Astronauts On The Moon
NASA has selected SpaceX to build a spacecraft to land the first astronauts on the Moon since 1972, choosing Elon Musk’s space company over competing proposals from Jeff Bezos’s Blue Origin and the aerospace firm Dynetics, officials announced Friday.
A derivative of SpaceX’s next-generation Starship vehicle will carry the astronauts to the lunar surface and launch the crew members back off the Moon. Under NASA’s plans, the astronauts will blast off from Earth on the agency’s heavy-lift Space Launch System rocket and fly an Orion capsule to the vicinity of the Moon, then transfer into the Starship for the final leg of the journey to the surface.

False Alarm: No Space Junk Threat After All To SpaceX Crew
SpaceX’s four astronauts had barely settled into orbit last Friday when they were ordered back into their spacesuits because of a potential collision with orbiting junk.
It turns out there was no object and no threat, the U.S. Space Command acknowledged Monday. The false alarm is under review.
Lt. Col. Erin Dick, a spokeswoman for Space Command, said it was believed at the time that an object was going to come close to the newly launched SpaceX capsule carrying a crew to the International Space Station.

M-42 Will Measure Radiation On The Moon
A long-term stay on the Moon would subject the human body to a high level of radiation, as radiation in space is generally many times stronger than it is on Earth. Before humans return to the Moon, the German Aerospace Center will send a small measuring device, the M-42 radiation detector, to Lacus Mortis to record radiation levels on the surface. It will travel there on board the commercial Peregrine Mission 1, which is scheduled to launch in late 2021.
M-42 weighs just 250 grams and is around 20 centimetres long. It will transmit radiation readings to Earth during its flight to the Moon and from the lunar surface.

Astronauts Need A Fridge. Engineers Are Building One That Works In Zero Gravity – And Upside Down.
For astronauts to go on long missions to the moon or Mars, they need a refrigerator. But today’s fridges aren’t designed to work in zero gravity – or upside down if oriented that way when a spacecraft lands on another planet.
A team of engineers from Purdue University, Air Squared Inc., and Whirlpool Corporation is working on building a fridge for zero gravity that operates in different orientations and just as well as the one in your kitchen, giving astronauts access to longer-lasting and more nutritious food.

NASA’s Perseverance Mars Rover Extracts First Oxygen from Red Planet
The growing list of “firsts” for Perseverance, NASA’s newest six-wheeled robot on the Martian surface, includes converting some of the Red Planet’s thin, carbon dioxide-rich atmosphere into oxygen. A toaster-size, experimental instrument aboard Perseverance called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) accomplished the task. The test took place April 20, the 60th Martian day, or sol, since the mission landed Feb. 18.
While the technology demonstration is just getting started, it could pave the way for science fiction to become science fact – isolating and storing oxygen on Mars to help power rockets that could lift astronauts off the planet’s surface. Such devices also might one day provide breathable air for astronauts themselves.

Who Controls Space
It is well known that the Straits of Gibraltar provide access to the Mediterranean Sea. In terms of strategic importance, this geographic phenomenon provides a control point for all seagoing traffic between the Atlantic Ocean and the Mediterranean Sea. Is there an analogous strategic structure for access to space?
For low-Earth orbit (LEO) traffic there is such a geographic phenomenon. Thanks to the physics of orbital mechanics, the equatorial plane offers the potential to act as an access-control point. The underlying reason is that all LEO traffic must cross the equator within every 50-minute time interval.

NASA’s Bold Bet On Starship For The Moon May Change Spaceflight Forever
When NASA astronauts return to the Moon in a few years, they will do so inside a lander that dwarfs that of the Apollo era. SpaceX’s Starship vehicle measures 50 meters from its nose cone to landing legs. By contrast, the cramped Lunar Module that carried Neil Armstrong and Buzz Aldrin down to the Moon in 1969 stood just 7 meters tall.
This is but one of many genuinely shocking aspects of NASA’s decision a week ago to award SpaceX—and only SpaceX—a contract to develop, test, and fly two missions to the lunar surface. The second flight, which will carry astronauts to the Moon, could launch as early as 2024.
