Astronauts Could Dust off Themselves and Equipment on the Moon With an Electron Beam

In the coming years, NASA will be sending astronauts to the Moon for the first time since the Apollo Era. This time, and as part of the Artemis Program, NASA also plans to build the necessary infrastructure to establish a sustained human presence on the Moon and eventually missions to Mars – including the Artemis Base Camp and the orbiting Lunar Gateway.

They’ll be getting some new equipment, such as the exploration Extravehicular Mobility Unity (xEMU) spacesuit and a fancy new lunar lander. Of course, as the Artemis astronauts will also have to deal with the same hazards as their predecessors – not the least of which is lunar dust (or regolith). Luckily, NASA is investigating a possible solution in the form of a handheld electron/ultraviolet (UV) device that could mitigate this hazard.

On March 19^th, 2021, the Biden Administration announced that they had nominated a successor for the role of NASA Administrator. Their nominee was Sen. Clarence William Nelson II (aka. Bill Nelson), a Democratic Senator from Florida, an attorney, and a former payload specialist at NASA. On Monday, May 3rd, he assumed the role of 14^th NASA Administrator during a ceremony where he was given the oath of office.

NASA Picks SpaceX to Land Astronauts on the Moon!

As part of the Artemis program, NASA is gearing up to send the “first woman and next man” to the Moon by 2024. Central to this is the development of the Space Launch System (SLS), the most powerful rocket since the Saturn V that took the Apollo astronauts to the Moon, and the Orion spacecraft. But after these elements transport astronauts to Lunar orbit, they will need a lander to take them to and from the surface.

For this reason, NASA contracted a number of commercial partners to develop a Human Landing System (HLS). After much consideration, NASA announced on Friday, April 16th, that they had selected SpaceX to continue developing their concept for a lunar lander. When American astronauts return to the Moon for the first time in fifty-two years, it will be a modified version of the Starship that will bring them there.

This Time NASA’s SLS Hotfire Goes the Full 8 Minutes

The core stage for the first flight of NASA’s Space Launch System rocket is seen in the B-2 Test Stand during a second hot fire test, Thursday, March 18, 2021, at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The four RS-25 engines fired for the full-duration of 8 minutes during the test and generated 1.6 million pounds of thrust. The hot fire test is the final stage of the Green Run test series, a comprehensive assessment of the Space Launch System’s core stage prior to launching the Artemis I mission to the Moon.

When NASA’s Space Launch System (SLS) is fully integrated, assembled, and finished with testing, it will be the most powerful rocket since the Saturn V that carried the Apollo astronauts to the Moon. To get it there, NASA has been conducting a testing campaign known as the Green Run, an 8-step assessment that culminates in a test-firing of all four of the Core’s RS-25 engines (aka. a “Hot Fire” test).

On January 16^th, NASA made its first attempt at a Green Run Hot Fire test at the Stennis Space Center’s B-2 Test Stand in Mississippi, which only lasted for about one minute. Another attempt was made on Thursday, March 18^th, where all four engines fired for 8 minutes and 19 seconds. This successful fire test is a crucial milestone for the SLS and brings it one step closer to sending astronauts back to the Moon.

A 1-Stage, Fully Reusable Lunar Lander Makes the Most Sense for Returning Humans to the Moon

When astronauts return to the Moon for the first time since the Apollo Era, they will be relying on a number of mission elements to get them there and back safely. This includes the Space Launch System (SLS) and Orion spacecraft that will launch a crew of four and carry them to the Moon. But until recently, the question of how they will get to and from the surface remained unresolved, as there were a few options.

To determine which would be best in terms of performance and cost, researchers from Skolkovo Institute of Science and Technology (Skoltech) in Moscow and the Massachusetts Institute of Technology (MIT) reviewed several dozen proposals. In the end, they determined that a one-stage reusable lunar lander that could transport astronauts to and from the orbiting Lunar Gateway was the best option.

Exploring the Moon’s Shadowed Regions Using Beamed Energy

In less than three years, astronauts will return to the Moon for the first time since the Apollo Era. As part of the Artemis Program, the purpose is not only to send crewed missions back to the lunar surface to explore and collect samples. This time around, there’s also the goal of establishing vital infrastructure (like the Lunar Gateway and a Base Camp) that will allow for “sustained lunar exploration.”

A key requirement for this ambitious plan is the provision of power, which can be difficult in regions like the South Pole-Aitken Basin – a cratered region that is permanently-shadowed. To address this, a researcher from the NASA Langley Research Center named Charles Taylor has proposed a novel concept known as “Light Bender.” Using telescope optics, this system would to capture and distribute sunlight on the Moon.

A Canadian Astronaut Will be on Artemis 2, Making it the Second Nation to Send Humans Into Deep Space (but not Walk on the Moon)

NASA and the Canadian Space Agency (CSA) recently announced that a Canadian astronaut will fly as part of the crew of Artemis II. This mission, scheduled for May of 2024, will see an Orion space capsule conduct a circumlunar flight where it flies around the Moon without landing. This will be the first of two crew opportunities that NASA will provide for Canadian astronauts on Artemis missions (as per the agreement).

Here are NASA’s Science Priorities for the Artemis Missions

In October of 2024, NASA will send astronauts to the Moon for the first time since the Apollo Era. After establishing orbit with their Orion spacecraft, a team of two astronauts (“the first woman and the next man”) will land in the Moon’s southern polar region. Over the course of a week, these astronauts will explore and investigate one of the region’s many permanently-shadowed craters.

As the first crewed lunar mission in over fifty years, this mission and those that follow will have a robust series of science objectives. These objectives were laid out in the Artemis III Science Definition Team Report, which was released to the public earlier this month. This report is a summary of the science plan prepared at the behest of NASA’s Science Mission Directorate (SMD) for the Artemis III mission.

NASA and Seven Countries Sign the Artemis Accords for the Exploration of the Moon. Russia Declined to Participate

It looks like Russia is thumbing its nose at international cooperation on the Moon. They’ve refused to sign the Artemis Accords, which are a set of rules governing Lunar exploration. NASA and seven other countries have signed on already, with more to come.
